Hi Fred,

Horses, especially my mare (16.2), have huge heads and tiny brains. I am 
always confounded by what she chooses to define as scary.  It is the 
gelding, however, that appears to be in charge of play time. They are 
often a riot to watch when they seem to get a "grass high" on the sweet, 
rich meadow grass.

I have so much wire that a set of radials AND a large loop are very 
possible.  It's just a matter of what time I feel like spending on 
them.  Just finding out how aluminum works as radiator in a wire antenna 
will be interesting.

I don't have any idea what the pH is like in the loamy, old forest floor 
of the meadow.  Never been touched by fertilizer of any kind. So we'll 
have to see whether the aluminum turns to powder or not.

As others have noted, N6LF's website is a goldmine for understanding 
radials, the performance of verticals, and other antenna issues. The 
ON4UN book is also worthwhile.

You might also want to study some of the antenna planning presentations 
on my website. k9yc.com/publish.htm  In addition to the obvious ones on 
vertical antenna height and a comparison of vertical and horizontal 
antennas at various heights, and with various ground quality, there's 
also one about getting on 160M from a relatively small lot, which is 
mostly about radial and counterpoise systems.

From experience, I can tell you that it is likely that the toroid was ruined by
the heat.  Once you heat it, the value changes, permanently, even if you replace
the wire.  I cooked a few in antenna tuners back in the 80s, before I learned
the cause.

I'd recommend you order a replacement (probably not expensive) and replace it at
your earliest convenience.  Also check with Elecraft about what other parts you
should check.  Be sure to tell them what happened, so they can accurately
estimate what issues you could have caused.

Here is a bit more info on the issue...

If my friend moves his frequency just out of the radio passband, as
shown on the P3, the problem go away...  The base noise level drops back
down to normal...  Only when his signal is within the passband as shown
on the P3 does the base noise level rise...  I also narrowed the filter
down to eliminate his signal, and as soon as his signal movers out of
the pass band, the problem ends...

Is it just that the K3 is not dealing with his signal levels?  This
happens when he is running 5 Watts, and he is 1/2 mile from me...

Hi Phil,
The Piglet creates a wireless network out of the box.  It is possible to
reconfigure the Piglet to join a home wireless network or a hotspot network
created by a mobile device.  When using it with iOS it's also possible to
reconfigure the Piglet to create an ad-hoc wireless network allowing for
simultaneous Wi-Fi and 3G/4G connectivity for rig control and callsign
lookups.  This reconfiguration can be done with a null modem adapter or
cable.

73,

Hello

how can I change the CW Sidetone Pitch via the remote interface?
I want to set it to a absolute value e.g. 550Hz.
Unfortunately the CW command is only for reading.

If you were talking K2, then I was going to say it may be possible with SW command, but not really recommended since you may have to realign your filters. Then again, if you store the alignment values for different pitches in advance...

But since you talk about KX3, then it seems you are indeed out of luck. I can understand why you might want to set the pitch programmatically if, for example, you are trying to fully automate the extended calibration/temperature compensation procedures.

I just checked that. It wasn't that. It's set to half span. It is almost like fix track and fix tune were active at the same time but only around that frequency. If I went a ~50KHz lower/higher the P3/K3 was fine.

It's not doing it now though.

Message-ID: <8D163308C05F0FC-2674-2F870@webmail-va053.sysops.aol.com>

I wish to report in after our radio club Field Day with glowing results using the KX3 and KXPA-100 combo
on CW operating as W1PBR from Thomaston, Maine.  We were able to work over 700 QSOs using an OCF Dipole while another 100 watt radio was up in the phone band on 40 and 20 during our operation.  The club had two OCF antennas up 40 ft end to end to minimize coupling.  There was some desensing but not enough to prevent dual band operation to continue.  I used N1MM with the SUCCI-R USB module to connect e the laptop to the KX3 and operated in both PTT or QSK with perfect connectivity. In addition to the regular laptop keyboard, I also used a separate function key pad programed to send the N1MM exchanges.  This was a learning curve for to get it all working in a month before the event with N1MM which I'd never used before.  Thanks to those who offered some steerage too.

Thanks for your reply,
Yes you are correct I would like to automate the sideband suppression
procedure and there it is stated to set the CW sidetone pitch to 550Hz which
I have no idea how to do this remotely.
I did not find any way to do in the programmers guide.

MacLoggerDX and MacLoggerDX HD (for the iPad) are the best loggers i've found for my Macs.
Very visual and VERY easy to setup/use.
They don't do rig control besides the normal QSYs when clicking on spots. But they do work with a bunch of rotators.
And support from the developer is awesome.

It looks like both RumLog and HamLog work with the Pignology Piglet to network between the computer and rig.  Reading the Piglet manual shows a way to use a Piglet generated network to talk to the rig.  Can this setup also connect simultaneously to my home WiFi for other internet based functions?  Is there any other issue that I should be concerned about with this setup?

Yes you are correct I would like to automate the sideband suppression
procedure and there it is stated to set the CW sidetone pitch to 550Hz which
I have no idea how to do this remotely.
I did not find any way to do in the programmers guide.

That indicates to me that your soundcard ADC is being overdriven, or 
that you have a bad soundcard.

The sound card could also be overdriven if another unrelated program has
changed the settings.

I've looked at logging with an iPad and haven't found it satisfactory yet
-- but I haven't tried a Piglet.  Just what control does the Piglet allow
with an iPad?

(1)  Can it fetch the frequency in use from the rig (K2 or KX3)?  (I think
yes.)
(2)  Can it enter a frequency from the iPad?
(3)  Can it send CW or PSK31 from the iPad?  (I think no.)
(4)  Do different logging apps have different capabilities?  For example,
using iSDR with a KX3, can you tap on a signal and move the transmitting
frequency to that?

My impression is that the only way to send from an iPad is through the USB
port, with something like an iMic in between, or playing audio into the
rig's mic.  Pretty kludgy.

Hi,

We are starting to focus on the Signalink soundcard itself...  I can't
imagine it is the Elecraft K3 failing, as a dead carrier does not cause
the spray, only when audio is being supplied to the transmitter, and
only when from the Signalink, does the problem happen...

But why will not the K3 filters take care of any too wide signals
coming from the SignalLink?

I am running JT65, the bandpass is on the order of 1 to 2 KHz, the
signalink is spraying across at least 1 KHz. with wideband noise.

While I hate to point fingers in this situation, the symptoms are
that of an unstable (noisy) sound card.  Given the documentation
of insufficient filtering, regulation and bypassing in that
particular device, a noisy USB power line (remember the computer
power supplies are switchers with the potential for broadband
hash) would directly modulate the codec (DAC), and the op-amp
audio stages feeding the transmitter.

I am considering using my K3 with an Ameritron AL-811H linear amplifier. Yeah, I know, the KPA-500 runs circles around it? but budget is tight here. Are there any interface problems that I should be aware of? If so, are there any fixes for them? Please let me know. Thanks.

Hi Joe,
The fellow is aware it is something on his end... I have been trying to
pin it to something on my end, and just can't...  We have known each
other for years and are on good enough terms that we can talk about it
with zero issues...  He is pretty sure it is the sound card as well...
We are just trying to devise tests to eliminate that.  He as a second
Signalink to test with, so that is the next step.  He will get a powered
USB hub shortly...  More as I get it...

Very straight forward to use a tube based amplifier. I ran an AL80A for 
a year with the K3 before I took the expensive leap. RF out of the K3 
into the amp - out of the amp into a tuner - out of the tuner into the 
antenna. A PTT line from the K3 to the amp. That is all you need.

Be sure to turn off the K3's internal tuner, if so equipped. Be careful 
about over driving the 811A tubes. That last statement means _READ THE 
INSTRUCTIONS_.

500 Watts is 500 Watts, regardless if it comes from some old inexpensive 
tubes or from a very expensive solid state amp. Don't fall into the 700 
Watts trap. The difference of an additional 200 Watts will never be 
noticed at the receiving end.

I use an AL-811H and the K3.  Just use a RCA to RCA plug to key the amp from 
the K3.  I have my K3 setup to 50W.

No issues.

Hi



I have an issue with my K3. I keep the antennas physically disconnected here and the radio had not been turned on for a week or so. Turned it on last night and it initially worked fine. Made a few Qs on 6m.



I then noticed that I could not switch the VFOs back and forth using the A/B button. Most of the buttons on the right hand side of the radio are "dead". I cannot change band, but can change mode. Some buttons appear to be "remapped". ie: the RX button turns the NB function on and off. The ANT button does the same thing for the NR function.



The archives suggest this can be fixed by using the restore feature (Holding Low Cut/Nom knob and cycling the power). I tried that 9saving the config first), but no luck. The Norm button also does not seem to be functioning correctly (pushing the knob has no effect, but I can change the cut).



Any ideas? Is there another to try a full restore?

Another thing to try is load the FPF firmware again. The FPF must match the
MCU, that is, when a set of firmware files is released, don't just load one
file from the set.

I have to agree with Sal, I've tried several Mac logging programs. HamLog is pretty darned good on the iPad and iPhone for quick logging when I'm not doing a lot and don't want to bother with a computer. But I use MacLoggerDX on my Mac and really like it a lot. It isn't a "real" contest logger, but worked quite nicely on Field Day when I managed 377 CW QSOs with just me and my K3 running 1E, not terribly seriously. I only had the USB/Serial cable connected for frequency/power/mode information for logging and an audio cable from the K3's line out to an iMic's input so I could run FLDIGI and run the CW decoder there as a backup to my ears...

MacLoggerDX and MacLoggerDX HD (for the iPad) are the best loggers i've found for my Macs.
Very visual and VERY easy to setup/use.
They don't do rig control besides the normal QSYs when clicking on spots. But they do work with a bunch of rotators.
And support from the developer is awesome.

I would look CQRLOG. It is fully supported, does HAMLIB and FLDIGI. I have not seen anything better for a true Linux logging software!

What recommendations for Linux logging/operating would fellow hams recommend and why?  This would be for use with a K2/KPA100 of recent vintage.

Subject: [Elecraft] K3 speaker amp chip bites the dust again
Message-ID: <B795B02D75C044CDAEA1D5E95AFC2102@Toshiba>

I guess I've blown the speaker amp IC in my K3 again.  This is 
the third time this has happened, twice in one radio and once in 
another.

In this case, the radio had both the AF Output Mod Kit (pair of 
470 ohm resistors) and the E85056 Audio Protection Assembly 
Circuit Board installed.

I was operating on Field Day, with headphones, as I usually do, 
when some onlookers wanted to hear what was going on.  I flipped 
SPKRS+PHONES=YES, then along came a strong signal, and poof! no 
speaker audio.

AGC SLP was zero, and AGC THR was 020.  Front panel AGC was FAST.

This failure is really getting old, especially at $120 a pop to 
get it fixed.

Um - what were you looking to learn from a 2M manual?

The conversion is a credit card sized pc board with two "very" tiny 
connectors to couple LO and ANT.  Screw in the sma connector, connect 
LO & ANT to pcb, two 4-40 machine screws hold it in place on top of 
the ATU, add a metal shield.  Final step screw thru the TO-220 PA 
transistor tab to the cabinet - less than an hour procedure.  All 
covered in the installation manual.

To use it with the KX3, go to page-21 of the KX3 Owner's Manual under 
"Transverter Bands" and follow the instructions for the KX3-2M.  I suggest:
XVn = XV1
XV1 RF = 144
XV1 IF = 50
XV1 PWR = 3.0
XV1 ADR = Trn 0

Use KX3 Frequency Memory Editor to add 2m channels.

That's it!

With SLP=0 and THR=20 you have essentially *no* AGC action.  That
means nothing is protecting the audio amplifier from strong inputs.

I leave it to Wayne or Lyle to calculate the overall gain from noise
floor to maximum DSP output but if one has set the audio for comfort
on a S4-S6 signal the audio amp is running along at roughly 1.5W
into the speaker.  When that S9+10 dB signal comes along and you have
no AGC even if the audio amplifier is expected to produce only 20 dB
more power, the 3.1W amplifier is going to die when asked to produce
more than 150 W of peak power.

Ramon:

If you do any CW, you might want to experiment with the TX DLY 
settings. I have seen where many suggest changing the setting from 
008 to somewhere around 020. You will have to
find which setting works best for you. Other than that you should 
have no problems using your amp.

It works fine, but if you're a cw op, don't expect QSK operation without
some extra hardware. With my AL-811H, I also used the Ameritron QSK-5
(with appropriate mod to AL-811H) to achieve QSK. It worked very well --
but not *quite* as very well as the KPA500 which I'm using now  ;-)

In a properly engineered design, the amp may clip like crazy, but it 
should be able to survive such abuse indefinitely....

My posting this morning about blowing the speaker amp chip was in 
error.  Further investigation reveals that I actually blew out 
the K3's internal speaker.  Ohmmeter measurement at the speaker 
terminals shows that the coil is wide open.  This is really good 
news, because the speaker is easily replaceable in the field.

It's also good news because it points out the efficacy of the 
E85056 protection mod.

My apologies for making a wrong assumption.  The symptoms were 
exactly the same as the two previous failures of the speaker amp.

One issue that someone obliquely mentioned in the various
replies that I feel requires greater emphasis, is that the
SignaLink USB box is, first and foremost, a sound "card"
and as such requires a great deal more current than a typical
USB device and should be plugged into a *powered* USB
hub. Granted, the power supplies for various powered USB
hubs are likely to be noisy (from the perspective of us hams,
anyway), and may need further treatment (chokes, bypass
capacitors, etc.). But if your SignaLink USB is plugged directly
into your laptop or desktop, know that it's drawing more current
than the USB (<3.0) spec allows, and that may be a significant
contributor?to the noise problems being reported in this thread.

Bought a Lighting to USB Camera adapter (Apple Brand) at Best Buy

Bought a Griffin iMic on Amazon because I couldn't find it at Best Buy or

Plugged in to iPad 4. After a few second get a message stating "This

Tried a flash drive with the USB adapter and got same message. Don't have
any other "Apple" accessories.

Tested the iMic on a Windows computer and it is functional.
Is this combo working for anybody reading this list? Are there other
components that will work?

Is there a way to search the archives?

I have the KX3, iMic, USB lightning adaptor, and iPad Air.  They all work 
together fine.  I have used the iMic and adaptors starting with the original 
iPad, iPad2, iPad3, and now Air, it has worked on all of them.  I have been 
using them for a few years now, including with the old 30-pin adaptors.  I 
used them this last weekend during some software testing.

Maybe your lightning USB adaptor or iMic is bad?  Do you have someone 
locally to test with?

We've also been working with Digital Confections to allow tuning the KX3 via 
the iPad with the Piglet/Pigtail devices.

Check to see if you have corroded pins on the front panel.

Elecraft has a mod for older K3's that switch them to all gold pins to 
prevent this.

You can always take the front panel off, and reseat them.

Subject: [Elecraft] K3 Front Panel Problem


Hi



I have an issue with my K3. I keep the antennas physically disconnected here 
and the radio had not been turned on for a week or so. Turned it on last 
night and it initially worked fine. Made a few Qs on 6m.



I then noticed that I could not switch the VFOs back and forth using the A/B 
button. Most of the buttons on the right hand side of the radio are "dead". 
I cannot change band, but can change mode. Some buttons appear to be 
"remapped". ie: the RX button turns the NB function on and off. The ANT 
button does the same thing for the NR function.



The archives suggest this can be fixed by using the restore feature (Holding 
Low Cut/Nom knob and cycling the power). I tried that 9saving the config 
first), but no luck. The Norm button also does not seem to be functioning 
correctly (pushing the knob has no effect, but I can change the cut).



Any ideas? Is there another to try a full restore?

I get the same message on my iPad 2 but it will still work - I just ignore
the message.  I get the same sort of thing with an eBay power adapter on my
iPhone5, I just ignore it and the phone charges normally.  In my experience
it's just Apple whinging about not buying their bit of kit!  YMMV of
course...

Phil,

You have a few options when it comes to logging software for Mac:

1. RUMlog - the one I use and really like. Cost is _free_. Excellent 
support for the K3. Has a K3 interface window; uses the K3 keyer; 
interfaces great with cocoaModem; has a DXCluster function; gray-line 
map; and that's just the stuff I have on the screen right now.
2. Aether - I bought this program and stopped receiving support. I 
absolutely do *not* recommend this program. Cost _$45_. It supposedly 
interfaces with Fldigi via script, but I could never get that to work.
3. MacLoggerDX - Has a shareware version you can try. I forget the 
limitations. Cost is _~$100_. I have not used the program. People love 
it or hate it.

The author of RUMlog also writes RUMped for contests. I have used it and 
it works well too.

I tried using an iPad to log. I didn't like it. It does not have true 
multi-tasking. Sure, it will do stuff in the background, but I don't 
like how it does that for amateur radio. To me, the iPad is an easy way 
to read email and/or browse the web, get RSS feeds, read electronic 
magazines, and get SOTA notifications ;). Not much else. Although the 
keyboard is larger than an iPhone, it still doesn't compare to a real 
keyboard when entering calls and other information.

I have tried both the Piglet and its predecessor. They both work very 
well. However, after experimenting with them a while, I wound up selling 
them and now have neither. It will allow you to set up an ad-hoc network 
and allow you to talk to both your WAN and the iPad simultaneously for 
call look ups.

If you truly want to go small with the computer, if it were me, I'd 
probably go with either a Macbook Pro *or* the Macbook Air. It depends 
on what else you want to do with the computer (i.e. video / photo 
editing, games, etc). I use an iMac and my wife has a MBP. To me, the 
13" screen on the MBP is a little small to have everything on the screen 
I like to see. On the other hand, the iMac's screen is so large I have 
to crane my neck to see the top of the screen with bifocals.

Good luck with your decision.

73,
Joel - W4JBB

HI Gang:

I also use RUMLog, and it does an excellent job of logging.  I'm not a  
constester, so I haven't tried RUMPed, but I'd wager it does the job  
as well.  I also use CocoaModem.

However, there's another option, which I used during Field Day, and  
that is the hardware device, Ham Central Terminal.  The HCT is  
designed to connect to Elecraft's K3 or KX3 (which is what I use) via  
the RS-232 port on the rigs.  The HCT is a good option for field use,  
since it is a stand-alone device, and can run many hours on an  
internal 9V battery... or external power source.. 12V is just fine.

The HCT "expands" the character display from the Elecraft rigs, so  
that you can see up to 80 decoded characters.  The decoding is done by  
the rig, so you need to use it with a K3 or KX3.  But, CW, PSK31 and  
RTTY work nicely.

The unit also has a logging function, and all you need do is input the  
other station's callsign, and the exchange.. which can be signal  
report, section, etc.. any text characters.  It will also generate an  
auto-incrementing serial number, if that's needed for a contest or  
event, and the number can be embedded into a macro string.  There's an  
internal clock which time-stamps the logged QSO, and the log file  
includes your frequency of operation and mode.  The HCT is also  
capable of transferring the log file into a computer via RS-232.  ADIF  
format, IIRC.


The HCT is not a laptop, and won't offer the features of a laptop.   
But then, while I would not want to drop my HCT off a cliff... I  
=sure= would not want my laptop to suffer that fate.  The HCT is -far-  
less expensive.  It's good in the outdoors, too, since it uses a  
transflective display making it readable in bright sun.

Hi Dave,

I'm glad you found a solution and it's good to know that the mods work. You
might want to take this opportunity to reevaluate your AGC settings. I use
headphones and anything above 010 is painful. I used to set it to 012 to
help my brain work weak signals but the occasional strong signal felt like
Q-tips piecing my ear drums. Ramping the AGC THR up to 020 is unthinkable
for me.

Message-ID: <AD457947-F88B-4048-A28E-818B9D1930AB@gmail.com>

Hi
I bought a K2 kit way way back; started to build it but then got distracted: divorce, moving, re-marrying - you get the picture:-) I?ve finally got back to it and have just started on Alignment 2.

All is well until I check the VCO frequency at P1. It is out of spec and doesn?t change when I spin the dial. The display does, but not the VCO frequency. 

The VCO does change when I change band.

I?ve checked through and the PLL is working, there is data in to the PLL and the VCXO works OK.

It all looks OK, so I?m not sure where to look next. The varactor diodes maybe?

I'm going to chine in here and give a vote for RUMLog.  The only thing I've
noticed is that for some reason RUMLog doesn't auto pull the details of the
call sign (Name, QTH, Grid square, Etc) I think it's something with the way
that I've got my software set up.

Subject: [Elecraft] K2 VCO frequency out of range and not changing

Gareth,

You did not supply much information with frequencies and voltage 
measurements, so I have to guess a bit about what your problem may be.

Usually when the VCO frequency at TP1 does not change, you will also 
find that the VCO voltage measured at the left end of R30 is at one of 
its extreme voltages - either about 8 volts or about zero volts.

The solution is to either adjust L30 or adjust the turns on T5 (or both) 
to get the frequency of the VCO into a range where the PLL can adjust it.

The easiest way I can tell you which way to move the frequency at TP1 is 
to tell you to look at the VCO table on the Schematic Key page (the 
first page of the schematics near the back of the manual.
Set the frequency on the VFO dial to the low end of a band (80 meters - 
3500 kHz is good).
Then measure the frequency at TP1 and compare it with the VFO frequency 
shown in the chart (for 80 meters it is 8415 kHz.
If the frequency at TP1 is too high or too low, adjust the turns of T5 
or adjust L30 to bring it onto frequency.  For gross adjustment, adjust 
the T5 turns spacing, and for fine adjustment use L30.
Note - if the frequency at TP1 is WAAAAY off, you may have a problem 
with the capacitors or relays in the VFO Range Select area.  See the RF 
Board schematic sheet 1.  The Schematic Key VFO chart tells you the 
capacitors used for each band - check the value and soldering and check 
the soldering of relays K13, K14, and K15.

Once you have the right frequency when tuned to 3500 kHz, tune to 4000 
kHz and measure the voltage at the left end of R30.  It should be able 
to be adjusted to something near 6 volts, and can then proceed to check 
the other bands as normal in the manual instructions.

73,
Don W3FPR

Another Mac user chiming -

My wife and I dumped our Dell / Windows computers about seven years ago and couldn't be happier. She now is using a MacBook Pro w/Retina display and I have two Mac's: a 27" iMac and an original version of the MacBook Air (MBA). When we got rid of the Dell's, I chose MacLoggerDX (MLDX). Another very good choice, IMHO. I started out running MLDX on the MBA, but because that poor old laptop is not capable of running the newest version of the Mac OS, I decided to move my MLDX over to the iMac. Still use the MBA for portable use; I log my QSO's on it and then export 'em and import 'em over on the iMac when we get home.

I'm quite happy with MLDX and the support that is provided by the author - Don Agro / VE3VRW. The software has NEVER failed in all the time I've been using it. I'd recommend it to anyone who is looking to move from PC to Mac. I believe there is a trial version available. Whether it works well for you may depend on what kind of operating you do. I an not a big contest operator. I had been on a quest for 5BWAS the past three years and spend some time operating in the ARRL SS, ARRL 160m, ARRL 10m contests, looking for needed states. I occasionally chase DX and have been known to waste an hour or so of my life trying to bust a pileup now and then! About 90 percent of my operating is CW, and the past couple months I've been using WSJT-X to operate my K3 on the JT65 and JT9 modes. I use MLDX for occasional rig control, but that's about it. For me, it is primarily a logging program and something that allows me to keep track of my 9BWAS and DXCC totals.

FWIW - I have a K3 and a KX3 and MLDX plays very well with both of these rigs.

In the "QSO" Menu do you have "Auto QRZ Lookup"  and "Add data to Log

My posting this morning about blowing the speaker amp chip was in 
error.? Further investigation reveals that I actually blew out 
the K3's internal speaker.? Ohmmeter measurement at the speaker 
terminals shows that the coil is wide open.? This is really good 
news, because the speaker is easily replaceable in the field.

It's also good news because it points out the efficacy of the 
E85056 protection mod.

My apologies for making a wrong assumption.? The symptoms were 
exactly the same as the two previous failures of the speaker amp.

I'm not sure where it is accessed but there is an audio limiter to prevent this from happening. Helps when AGC is OFF.

Message-ID: <CFD9DD7C.48F0%edauer@law.du.edu>


Is anyone using a Mac (Apple) monitor and/or computer with the P3 SVGA option?  Here's my image of the perfect world:  Running a logging program on a Macbook Air and being able to toggle quickly from the keyboard between that program and the P3 output, on the Macbook screen.  A near-perfect world would be an outboard monitor capable of the same quick toggle, from P3's SVGA display to logging program resident on the Mac.  Possible?

Mac Logger DX is great, but I use RUMlog and RUMped. These have most if 
not all of the functionality of MLDX, but for free. I've got no problem 
with MLDX, but when I can get the same functionality for free, I'm going 
to choose the free program every time. Well, not exactly free. I liked 
RUMlog and RUMped so much, I donated some money to the author, DL2RUM.

So, you probably can't go wrong with either RUMlog or MLDX, but you'll 
have to pay for one, but not the other.

Nobody ever mentions HamLog for Mac.  :)

To answer some questions directed at me about the Piglet with HamLog on
iOS...

(1)  Can it fetch the frequency in use from the rig (K2 or KX3)?
Yes.
(2)  Can it enter a frequency from the iPad?
Yes.  For K3 and KX3 it actually puts the whole face of the radio to iPad.
(3)  Can it send CW or PSK31 from the iPad?
Yes, it's via keyboard though and only what the radio decodes, no waterfall
or decode via audio (yet).

Subject: [Elecraft] KAT500 Following K3 not always working
Message-ID: <000001cf964e$adb6fd60$0924f820$@net>

I have a brand new KAT500 connected with my K3 and KPA500.  I've set the K3
CONFIG:KAT3 setting to KAT500Y but the KAT doesn't seem to always follow the
K3 when I change bands.  I make sure that when I power up, I power the KAT
first then the K3 and finally the KPA.

 

Is there something I'm missing?

Subject: [Elecraft] Elecraft Customer Care Bravo!
Message-ID: <00b601cf964e$edf84500$c9e8cf00$@net>

I can't say enough great things about Elecraft customer care.  Another
example popped up today when I needed a K3 DVK card shipped on an overnight
shipment so I could install it over the holiday weekend.  Of course, I
didn't submit my order on the web until 2:30 PM California time and shipping
had stopped for the day.  I called Elecraft to see if there was any chance
they could slide this small shipment out the door today via overnight
delivery and sure enough, they were able to make it happen.  I don't want to
set the expectation that something special like that could happen every time
but Elecraft (I forgot the young lady's name, Loretta maybe?)  made it
happen this time and really saved me some major stress.  I need to take this
particular K3 to the WRTC2014 next week in Boston since one of the
competitors needed a backup K3 in case their K3 went down and I volunteered
it but it didn't have a DVK (which will be needed in the competition).  Now
it will have a DVK and I owe it all to Elecraft's fantastic customer care
philosophy.
 
Awesome!
 
Thanks again,
 
Bob K5WA

Hey, Nick:

Darn, I forgot that HamLog is also a Mac app.  I also use HamLog  
(usually on my iPhone) when operating.  My level of activity is such  
that I don't need a super-duper logging app.  HamLog does fine.  I  
didn't realize that it also was a Mac app!!!

Thank you for the replies and encouragement Terry, Bill and Stephen.

I had plugged in the iMic while away from the radio and got the not
supported messages while not plugged into the radio.

Tonight, I did a full power off of the iPad with the iMic unplugged,
powered it on, plugged in the iMic with the radio connected and then
started the iSDR app.

Lo and behold it worked! Not even a not supported message!

Thanks again!

Hi,I am sending this message here in the hopes that I can get some help from Elecraft concerning emails not being answered.
Over the last couple of months I have sent several emails to various people and support at Elecraft and have never had a reply. This has also happened in the past when I was working with tech support on an issue with my KPA500. I have called to try and have this resolved but it did not get resolved.
One email I send a few weeks ago, was answered a number of days later with an apology that my message was in the persons spam folder. However a follow up was not replied to even though it was resent several times.
I am sure that this is an error somewhere in the Elecraft email server. I own the complete K line as well as the complete KX3 line. I am a developer of software targeting to the Elecraft products and at least 5 people have bought a K3 or KX3 as a result of my software, so it is important for me to have some feedback at times. I also have provided comments as to bugs that I have found.
Could someone please resolved this for me? Thanks for your understanding.

Hello,I am attempting to program the threshold values in the Text decode seeings.
Using the K3 utility command tester, I issue the following commands:
SWH40; //select text decode - works as expected
DS; returns the expected VFO A text. For example if the threshold is at 11 I get?DSTKR@@11@\xA0\x80;


I then issue an UP; of a DN; and the value never changes. Based on all of the menu items which work this way, I would expect the threshold value to change but nothing happens.


Is this a bug, or an omission, or am I doing something incorrectly?
Thanks for your help.

Glenn,

You are correct, it is not currently listed.  I have a suspicion it is 
because the blue trimmer capacitors used on the 4 band board are no 
longer available.
I recently assembled a KXB3080 option for a KX1 which used to use the 
same capacitors and noticed that the trimmers had been changed to a new 
type, so I suspect the old ones are "unobtainium".
This may be a temporary removal until all the manufacturing paperwork 
has been updated.  Perhaps someone closer to the supply situation at 
Elecraft than I will respond with a positive answer.

Don W3FPR

Message-ID: <14B7DE3C16254048BC1511CCE5CEF370@LarsEdwards>

I?m hoping for some advice on where to start troubleshooting a problem that started this afternoon.

Before I start digging into the K2 perhaps someone on the list has had a similar problem and can help save some time in troubleshooting and repair.

Here is what I?m experiencing.

While listening to cw on my K2 (s/n 2711, 15 W) the unit suddenly started keying dots.  I shut the unit down and removed the key but when I powered the unit on the problem remained the same.
I shut the K2 off, removed the microphone so there was no microphone or key attached, turned the unit back on and the problem is still there.

Thanks in advance for any ideas on where to start.

Sounds like C1 may be short circuit, jack J1 may have failed, or there could be a short somewhere between jack J1, the trace that runs along the RF board from J1 to J8 pin 18, or where the corresponding track on the control board runs to the MCU pin 30. There's not much to go wrong, so I'd suggest first check carefully for shorts/solder bridges, then try removing C1, and if it still fails then replace jack J1.

Lars,

First, turn the power all the way down and attach a dummy load to 
protect your K2.
It will have to be a process of elimination to determine where the 
problem source may be.

You are looking for a short on the dot line.  Keep the K2 in CW mode.

First, remove the KSB2 board (no jumpers required for this test, you 
will still hear sidetone), then see if the problem continues.  If it 
stops, the problem is on the KSB2 board - check resistance to ground at 
P1 pin 4 - if close to zero, remove the KSB2 firmware.  If the 
resistance increases, replace the firmware chip.

If the problem continues with the KSB2 removed, power off, then check 
the resistance to ground at both ends of R1 (you may want to remove the 
left side panel for easier access to R1).
Is there a lower resistance on the side toward the key jack?  If so, 
replace the key jack.
If the resistance is lower on the side of R1 away from the key jack, try 
removing the control board and see if the resistance goes up. If it 
does, you may have a shorted MCU pin - remove the MCU and put the 
Control board back in.  If the resistance stays high, replace the MCU 
firmware IC.

Now if  the resistance stayed low with the Control Panel removed, you 
have one more step to do - remove the Front Panel and check the 
resistance again.  If it is now high (greater than 1k), you have a 
problem on the Front Panel.  Check for solder bridges or other things 
that may have bridged a connection - look especially at the microphone 
configuration header and the mic jack (the PTT line is the same as the 
DOT line).

Don W3FPR

I was playing with Bluetooth serial links for another project and, just
on a whim, cobbled up a MAX232A with an HC-06 Bluetooth module.
Very nice to run ACLog's rig interface, or HRDeluxe, wirelessly from the
Lazy Boy.
It worked so nicely I laid out out a little PCB that would plug right
onto the DB9 on the back of the K2, stealing its few MA from the KIO2
connector.

But then... reality check... surely I'm re-inventing the wheel. A modest
web search didn't turn up much that is recent.
Anybody done this, or know of such a gadget?

Subject: [Elecraft] What hardware mods would be best?
Message-ID: <1404429714485-7590842.post@n2.nabble.com>

Hi everybody,

It has been a long time (2 or 3 years) since I have posted or looked at this
mailing list since I haven't been very busy with the hobby due to various
reasons such a work and family. 
After not being used for almost a year, I finally got to use my K3 again
this holiday in Denmark (call OV2T). 

Recently I have heard from a friend, who also has a K3, that there have been
a couple of hardware modification for the K3. My K3 (serial number 1849)
hasn't had any hardware updates at all and I was wondering which, if any,
would be useful for me.
Options:
- K3/100
- KDVR3
- KFL3A 400 Hz, 1.8 KHz, 2.1 KHz, 2.7KHz filters
- KAT3 

My K3 is mainly used in for Phone, occasionally for digital modes and CW. I
like contesting and doing Field day events, hence my choice for the K3.
I mostly use it with my headset (Heil Pro Set Plus) but I plan on using it
with a desk microphone and a pair of speakers in my new shack. The reason
for that is that with my headset on I won't be able to hear my wife. Now,
that's not necessarily a bad thing but I don't want her to get mad at me for
not listening at all. 

Any comments on what hardware modification could be useful for me would be
greatly appreciated.

Best 73,

Maarten PD2T/OV2T

Considering that a particular K3 might be sold and resold, the kindest
thing is to do all the mods. The next owner might not have your particular
collection of interest and usage.

What noise blanker settings are best for the removal of lightning 
static? There must be some - maybe?

My TS480 does a far better job of cleaning up the static than does the 
K3. Already reduced the RF Gain and use the ATT. Then I tried all kinds 
of setting - no go.
Anyone have a magic pill on this?

NB is good at taking care of pulse noise such as ignition or static noise. NR is good at taking care of continuous noise, but not for pulse noise.
My location is in noise rich environment caused by power line nearby. So, nature of the strong noise is continuous noise, which I use NR as well as adjusting RF gain and AGC level.
NB/NR setting depends on noise strength and nature of the noise. I often adjust NB/NR settings to have better receive performance.

I'm not sure what you're asking, but here's what I do. I assign two menu 
functions to the soft keys -- the Fixed Track on/ff toggle, and the 
Peak/Average toggle. I use the remaining buttons for the range of span 
settings that I most often use - 2 kHz, 10 kHz, 20 kHz, 50 kHz, 100 kHz, 
and 200 kHz.

I use averaging nearly all the time, with long averaging times. I use a 
scale of 24 dB for day to day operating, 42 dB for contesting, and as 
low as 18 dB for weak signal operation on VHF. I carefully set the base 
of the display so that it's just above the noise level.This makes empty 
space black or near black, so that weak signals are most visible in the 
waterfall.

There are separate averaging settings for the spectrum display and for 
the waterfall. I use the longest settings for all of them.

Hi Guy,

Thank you for your reply. I understand what you are saying. The thought of
selling the K3 has crossed my mind several times. However, having played
with almost all the rigs of the competitors (TS 990, FTdx 9000, FTdx 5000,
IC 7700/7800), I'm always glad to return to my K3. I certainly have no
intention to sell my K3 nor can I afford to replace my K3 with a comparable
transceiver (assuming there is a TRX that comes close to the K3).
Furthermore, doing all the mods for the K3 will cost me over $200,- +
shipping + tax. And then they need to be installed as well which
unfortunately I myself am not comfortable doing.

So it may be the kindest thing to do, it's not the economical thing to do.
With no intention of selling my K3 I would rather be kind to my bank account

There's a couple of ways to use Bluetooth with the K2 on my list of mods
(internal/external), and there are more on the mailing list. Some of them
are some years old, so maybe some better ways are possible today?

Emne: [Elecraft] Emails to Elecraft are not answered
  

Hi,I am sending this message here in the hopes that I can get some help from Elecraft concerning emails not being answered.
Over the last couple of months I have sent several emails to various people and support at Elecraft and have never had a reply. This has also happened in the past when I was working with tech support on an issue with my KPA500. I have called to try and have this resolved but it did not get resolved.
One email I send a few weeks ago, was answered a number of days later with an apology that my message was in the persons spam folder. However a follow up was not replied to even though it was resent several times.
I am sure that this is an error somewhere in the Elecraft email server. I own the complete K line as well as the complete KX3 line. I am a developer of software targeting to the Elecraft products and at least 5 people have bought a K3 or KX3 as a result of my software, so it is important for me to have some feedback at times. I also have provided comments as to bugs that I have found.
Could someone please resolved this for me? Thanks for your understanding.

Subject: [Elecraft] K3 - noise reduction query
Message-ID: <53B6A964.10600@nycap.rr.com>

It is lightning season and I have been floundering around the menus on 
the K3's DSP NR system. I have found no setting that really do much of 
clean-up on lightning static. I also have tried using the ATT and RF 
Gain settings also.

The sad part is that My cheap little Kenwood TS480 does a much better 
job of cleaning up this noise.

Of course, lightning static is very random and difficult to reduce. My 
use of HF is 40 and 75, so directional antennas are not an option - as 
some suggested.

Please do not answer with direct emails - the group needs to share in 
this knowledge.

Thanks,

You are trolling for complaints on the Elecraft noise reduction - not
looking for a "solution".  The Elecraft noise reduction is designed for
"smooth" noise - not impulse noise which is a noise blanker function.

A smooth noise reduction system (LMS)  operates by forming bandpass
filters around what it determines to be "signal" components and passing
just the "signal".  You will have better results with lightning by
working with the noise blanker - probably on a "long" setting - as
it is designed to work with fast rise time signals.

I am trolling for nothing other than suggestions and possibly successful 
settings used by other K3 users. The purpose of this reflector is to aid 
owners/users of Elecraft equipment.

Bill,

I suggest you use your TS-480 rather than the K3 if that's what works for you. Personally, mine has been gathering dust since I got my K3.

Hi Bill,

Are you using; NR, IF NB, or dsp NB?

Actually - all of the above. I have spent a lot of time playing with all 
the NB and NR settings (there are many combinations) and have 
incorporated the ATT and reduced RF Gain into the mix. My understanding 
is bringing in the RF at a lower level allows the various DSP devices to 
get a running start at cleaning up the noise. So far I have had very 
little success.

I am hoping someone out there has come up with a magic bullet setting 
(or even a workable setting) that can be shared. This has been a summer 
with loads of lightning static.

Thanks,

The K3 is far more capable than the 480 and has the entire line running 
from it. I should not have to be content with the 480 - that is why I 
have the K-Line.

That said, I am sure there is a setting out there that will work - I 
have not found it - hence, the reason I ask.

Probably K3 NB is not effective filtering your particular noise. Impulsive
noise is very hard of characterize because are infinite patterns possible.
I have filtered majority of arching noise but eventually not was possible.
You are tested NB analog and NB digital and combined both?
I remember a 11m radio (3-5825A) with a NB more effective than TS-440S,
with only a particular noise.
Recently I discovered a static noise effectively filtered by IC-736 but a
IC-781 wasn't capable
We must accepts not cheap equipment wasn't capable filter a type of noise
is frustrating.

Just now i'm suffering a impulsive noise not filtered by IC-7700,
IC-756proIII, IC-781, however K3 is capable filter this noise with a beside
artifacts, audio become distorted because only is filtered with aggressive
adjustments.

Bill,

With the NB, it will often help to *increase* the RF gain or turn on the 
preamp.  The noise impulse must be above a threshold before it will 
trigger the blanking function.  Keep in mind that setting the NB so the 
blanking pulse is wider may result in distorted signals. It does just 
what the name suggests, it puts a blank *hole* in the received signal.

The NB is better for fast rise time impulse noise such as lightning and 
automotive ignition noise.  NR will do nothing to help that type noise.

I do not believe there is any one magic bullet.  What works for one 
noise may not work for the next one.

I would suspect that was caused by some frustrated individual who could not
figure out the concept of unsubscribing from the list and instead began
marking list emails as spam in attempt to make them stop.

Bug users,

and sending is smoother and more regular. Before Jim's post I did not know

All electronic keyers should come with a Lake Erie Swing mode. Makes 
more sense than having two iambic modes.

As long as the Iambic mode you replace isn't *my* Iambic mode. :-)  Why 
is it called "Lake Erie Swing?"  For that matter, why are there two 
Iambic modes in the first place?

Here's a couple of recordings of W0BMU and the Lake Erie swing that Buzz 
mentions. Listen online or d/l them. The bands used to be full of 
interesting and quirky fists and styles like this. Not unlike speech 
patterns some were quite beautiful, some were in-your-face obnoxious. 
That was before non-meat code readers and (gakk!) keyboards.

I always thought the Lake Erie swing was easy to copy in the speed range 
of most ham QSOs. It has an informal chatty feel to it.

Anyway, for those who want to remember and for those who never knew:

Who knows?  I always heard it called a "banana boat swing" but then
my CW mentors were from around Lake Erie <G>.

> For that matter, why are there two Iambic modes in the first place?

The original "Curtis" Iambic mode completed the element (dot or dash)
being sent when [both] paddles were released at the same time.  The
iambic mode in the AccuKeyer had a logic error - the element memories
were set as soon as the previous element completed - that completed the
element being sent and then sent the *opposite* element if both paddles
were released at the same time.  This became known as Iambic B to
distinguish it from the original Curtis iambic (Iambic A) mode.

Those who learned on an AccuKeyer generally have problems with Curtis
and vice versa.  For an Iambic B (Accukeyer) user, trying to use an
Iambic A keyer generally results in problems with incomplete letters
(C, K, R, etc.) while for an Iambic A user trying to use an Iambic B
keyer, the problems are generally more severe with extra elements
added to the end of nearly any character which ends in alternating
elements.

Wayne,

OK, I was not saying a manual would not be useful or appreciated, 
only that basic info to start using the KX3-2M is already 
available.  I am using mine on SSB and local FM channels.  I even 
added the local NOAA wx channel at 162.475 MHz without any more 
information than what is in the KX3 manual (easier to do using the 
memory editor sw).

Certainly, safe handling of the credit-card sized module is important 
so careful reading of the installation is advised.  Even as a field 
tester, I made a simple mistake that resulted in 0.3w vs 3.0w RF 
output.  Fortunately no permanent harm came from that.  I'm getting 
great on-air reports using the KX3-2M.  Next is adding a 30w 
amplifier (RFC-2-23).

I'll be interested in seeing the new 2m manual.

73, Ed - KL7UW

Does anyone know the structure of the AUXBUS protocol? I want to make a decoder for a KX3 to decode more than 3 VHF bands that the KRC2 supports.

Thanks!!!

Hi Terry,

The AuxBus isn't yet supported by the KX3. It's on my list. But it will behave exactly the same as a K3 in this regard.

The KRC2 can decode up to 7 bands, I believe, but we haven't tried one with the KX3 yet (since the AuxBus isn't yet supported).

Hi Ed,

Glad to hear the module is working well for you. Yes, the basics are covered pretty well even in the KX3 owner's manual (latest release, plus errata). the KX3-2M/-4M manual goes into great details on installation, setup, specs, etc.

tnx

Eric -- 

Thanks for sharing the recordings.  I've heard fists somewhat like that
but none quite so distinctive.  I tried to figure out what makes the swing
sound the way it does.  I don't have a scope or any other device to
visualize or capture it, so this is just by ear - it seems that his dahs
are much more than three times as long as his dits, and that the leading
dah in a character that begins with a dah is longer than the following
dahs.  Maybe someone with the right equipment (and the time to spend on
it) could do a better analysis.  I would be interesting to know.

Both the K3 and the KX3 allow for some personalization (as do many other
rigs), by changing the weight ratios -- i.e. the ratios of dit length to
dah length and of the element length to the inter-element spacing.  There
may be other variables in the F/W as well that I haven't looked at.  I
have never played with it, being an old stick-in-the-mud 3:1 curmudgeon;
but I've wondered whether an idiosyncratic weighting would help make a
signal stand out in a pile-up or make for better copy in the QRM . . .
Anyone know?

Ted, KN1CBR

I was able to leave most of the cables between my computer and the KX3 disconnected. I did use the KX3 to USB interface so the N3FJP software could log my frequency for each contact. I found by using FAST-PLAY on the KX3 that I did not have to touch the mouse as N3FJP just kept doing what I wanted and the KX3 was handy beside the computer. A touch of 2 buttons completed most contacts. The built in paddle was used about twice during the entire contest. Once again thanks Wayne as I considered this a wonderful improvement to the firmware.

I wouldn't intentionally develop an idiosyncratic fist to make me stand 
out, but in the 60's I could identify all of my regular on the air ham 
friends by their individual fists without every hearing a call.

The main characteristic of the Lake Erie swing was dots send at about 40 
wpm and dashes at whatever the op chose. It was easy to send very fast 
dots with a bug (being automatic!), but dashes were much slower for most 
operators. I think the rationale was the 40 wpm dots brought the overall 
speed up, even though the op was still sending dashes at a lower capability.

Eventually, though, I think the LE swing just became a dialect that 
propagated through a particular set of operators (Erie Canal for LE 
swing and marine ops for banana boat swing?), and spread from there. It 
may not even have been any more efficient--it was just the way you sent 
in a particular group to identify yourself and be accepted. The same way 
that non-Southerners start using y'all all over the place an hour after 
they land at a Southern airport.

I don't have a K3, so I don't know if it can be set up to replicate an 
LE swing. It could if you can independently vary the speed of dots and 
dashes. You wouldn't have the sometimes difficult corruption of random 
extra dots and weird variations in dash length, but you could have the 
best of LE swing which was the lilt and charm of the faster dots. If I 
were to try it, I'd probably set dash length to 20 wpm equivalent and 
dot to 40 wpm. It would be fun to try, but not everyone likes to hear a 
Lake Erie swing--or Southern accents for that matter.

Not true - first the question was asked and answered if nothing
else by the lack of responses.  Second - the question was asking
for information to make the noise reduction do something that it
is not designed to do (reduce impulse noise) and comparing it to
a different product in an unfavorable light.

Asking a loaded question - one that has been answered previously -
in a manner to provoke a negative response is the very essence of
trolling.

What antenna lengths are you using on 160M with your KX3 or  KXPA100
internal tuner? What is best for 160-6 meters? I like making my own
antennas with wire.

I usually have to give up one band or another cause it just would not tune
 up on a certain band.

I have tried to stay with in these guide lines.

Jim,

Having one antenna to cover 160 meters through 6 meters is asking a *lot*.
But I would suggest starting with a halfwave on the lowest frequency band.
If that is a half wave on 160, then the pattern will begin to break into 
multiple lobes beginning at 20 meters and up.  Whether those lobes will 
be in a favorable direction for you is a different question.

Of course, you would feed such an antenna with open wire line or ladder 
line because those are relatively low loss and losses will increase as 
the SWR increases.  The feedline will have a high SWR on some bands.

The length of the feedline makes a big difference in the ability of any 
given tuner to resolve the impedance at the shack end.  A few sessions 
with the TLW (Transmission Line for Windows) may be helpful in 
determining the best feedline length compromise that ends up with a 
usable impedance at the shack end for all bands considered.  Of course 
it will be necessary to know the antenna feedpoint for each band to know 
how to find the impedance transformation that will be present at the 
shack end.  Antenna modeling can answer that antenna feedpoint impedance 
question.

If the feedpoint impedance at the shack end is out of range of the tuner 
being used, some additional capacitance or inductance placed either 
across the feedline or in series with it may be necessary to bring the 
impedance into a range that the tuner can handle.

Thirdly, you need a good current mode choke (balun) to keep RF out of 
the shack and to provide a balanced to unbalanced transformation.  Its 
impedance must be at least 10 times (more is better) the highest line 
impedance seen at the place that current mode choke is placed.

All the above must be taken into consideration for any antenna.

Yes, there is much more to your question than just the lengths of the 
radiator.  Any answers that do not also include the type and length of 
the feedline may not be able to be duplicated given your particular 
physical situation.  Antennas and feedlines are just like that.  Of 
course an antenna whose feedpoint impedance is matched to the 
transmission line characteristic impedance can use any length of that 
feedline, but that is not the usual case for multiband antennas.

You will likely have better luck with 2 antennas - one for the low HF 
bands and another for the upper HF bands - those are normally easier to 
deal with.  The ideal is a resonant antenna for each band, or fan 
antennas covering multiple bands (I restrict those to 3 bands because 
the interaction makes tuning frustrating).

Good luck on finding that "magic" length - many have tried over the 
years and all are compromises.

I have tried a 6:1 balun at the feed point of the inverted L. How ever it
presents a significant loss while QRP with 5 W. Just does not have enough
isolation from ground. yet it presents a good match.  Go figure.

The helpful spirit of this reflector was not shown today by you and my

Jim,

A lossy balun will provide a good match - just the same as a dummy load 
resistor provides a good match (that is a near 100% loss if you are 
considering the radiation capability).

Everything that loads does not make a good radiator.

Why not consider a fan dipole. 160, 40, and 17 ?????? Model it on an antenna program. You're still going to  need a tunner .

If you are talking about SSB on 80 and 40 - I was playing with trying to 
copy
the K2M on 40 M SSB last nite thru all the qrn - something to play with
is the SSB bandwidth and shifting the band- it makes a lot of difference
depending on how the guy has his audio tailored or how his voice is.

You also have a lot of AGC handles to play with - last night reducing
slope and playing with threshold made  significant differences at times.

I don't think there is any magic bullet  - conditions change and what works
one time or at one location  will be different another time.  What works for
one person . one location is very unlikely to be the solution at another
place.

I used TenTec Orions  for about 10 years - they had an incredible NB for
clean line noise spikes  BUT BUT if there were any strong signals anywhere
near (25 -50 khz or more) where you were listening  , the blanker
was useless -but absolutely  great on a quiet band.

I have never found a K3 line noise NB setting as good as the ORION  BUT BUT
I can get decent blanking in crowded band conditions -- I will take that any 
day over
unusable incredible . Years ago Collins used to drive their blanker with a 
separate
noise RX at about 40 mhz - often wished the Orion did that .

NR is a whole different story - I have already been thru  ten years of NR 
discussions,
in my case for me NR F1-1  is as good as anything I have used on either CW 
or SSB
but that is for me - a top flight contester friend across town with Orion 
and K3
to A/B and who lives in a 10 dB quieter location has entirely different 
opinions.
What works for him is entirely different for me.

NO MAGIC BULLET.

My two cents worth .

A dummy load presents a good match.  It just doesn't get out well.

Trying to have one antenna do 160-6 meters is just too much if you care about
getting out.  One antenna can do a fair job on two bands, sometimes, three if
done right.  But if you expect to have more than a dummy load on multiple bands,
you need to plan on having multiple antennas.

OK, thanks for the recordings Eric.  It isn't unique to hams, or to Erie 
Canal RO's.  I worked Coastal Marine from So California in 56-57 while I 
was a senior in high school.  That "swing" was fairly common, as were a 
large number of fists I can only categorize as "truly sloppy," like an 
air traffic controller giving a clearance with a mouthful of marbles.

His signal was clean however, and very easy to copy.  Transmitters 
afloat were usually powered by M-G sets which often modulated the 
carrier with a whine.  MCW from an audio oscillator was common on 500 Kc 
[emergency receivers afloat were usually unpowered crystal sets with no 
BFO], and key down dragged the M-G down.  The result was a carrier that 
chirped, sometimes through the passband of my receiver, a steady whine 
that chirped, and the MCW audio that chirped, each in it's own key and 
tempo.

I sort of assumed the name came from the RO's on the freighters in the 
Great Lakes, but never really knew.

Why do you need a tuner with a well designed fan dipole.  The lengths of 
each set of wires can be trimmed to allow coax feed.

I have 2 fan dipoles here, one for 20, 15, and 10 and another for 30, 
17, and 12 meters.  Each fed with a single coax.
Restricting them to 3 bands simplifies the tuning difficulties 
associated with interaction.  Keeping the wires about 1 foot apart 
reduces that interaction.

I do not mix bands that are 3rd harmonic related on the same coax, it 
just complicates things - in other words, I do not mix radiators for 80 
and 30 on the same coax, the same for radiators for 40 and 15 meters.

The KISS principle applies.

I knew there was a history to this.  Related question:  About the end of 
1956, I and a couple of my teen friends built "electronic keyers" from 
some magazine article which is long gone from my memory.  I remember 
they had 8 or so dual triodes [12AT7's/12AU7's ??], had self-completing 
dots and dashes, and nothing else.  With the power supply, mine weighed 
about a small brick and was similar in size. Used a relay for the 
then-ubiquitous cathode keying.  We modified our bugs to key them.

I'm fairly certain the design pre-dated the TO-Keyer, I think the TO 
came about 10 years later, and as I recall used fewer tubes.  If any 
OT's remember the 50's well enough to identify my keyer, I'd appreciate 
hearing from you.  I had an opportunity to operate as HS1FJ for a few 
weeks in the mid-60's, Dad sent me my keyer and Lionel J-36, and when we 
went back to war, I never saw either of them again.

Oops,

Jim  
I use two antennas here at my place. 
For 80 and 160 I use a 170 foot long wire running from just over my feed line entry to a point 40 ft below a branch on a 75 ft pine, up to to the branch and over to another tree ( kinda like a "Z"). This is fed to an "L Match" made from a section of coil and a variable capacitor for 80 and I add an additional fixed cap for 160. 

For higher bands I have a 40-20-10 meter "fan" dipole that my K-Line (& my KX3-Line") will tune on 40-20-17-15-12-10-6 meters. Many will say "it can't work" but please don't tell my radios!  The Elecraft tuners can tune anything!  
I once worked a friend who'd just moved and was using a "GutterTron" ant in the CQWW. Yeah, the gutter and downspout fed against a ground-rod. 

Another friend loaded up the liner in his chimney, called a GutterTron. 

Have fun. Try anything. It just might work. You can make a lot of antennas from a $45.00 spool of THHN and plastic "cutting" board from Walmart. About 2/3rds the price of a G5RV.

Jim,

Try 102 feet (or so) for each leg of a dipole fed with twinlead or open-wire line. This is not a close multiple of a half-wave on any band from 160-6 meters, so it stands a chance of providing a reasonable match on all bands. 

If the internal tuners can't find a match on one or two bands, adjust the length of one or both sides by a couple of feet experimentally. It'll be slightly imbalanced if it ends up off-center-fed, but this won't have much practical impact.

At my QTH I use a 4:1 balun (Elecraft BL2) right at the radio to feed this antenna. The BL2 also has a 4:1/1:1 switch. I use the 4:1 setting for all but one band, where the 1:1 setting makes it easier on the ATU. Note that if you don't get to a low SWR when you first tap ATU TUNE, tap again within 5 seconds and the tuner will try more LC combinations. This will nearly always provide a 2:1 or better match unless the antenna presents a very high impedance. 

The KXAT3 will match a wider range than the KXAT100. For safety reasons, our QRO ATUs put limits on the SWR they will try to match.

Use a good ground at the station. If in your installation you experience any RFI at higher power, drop back to a lower level.

Back in the day I used relatively fast dots so I could vary my speed
without readjusting the weights on the vibrating arm. Dunno whether they
were 40 wpm dots or, more likely, somewhat slower than that. And I didn't
know that was called a "Lake Erie Swing."

I worked all over the country on 10 and 15 meters recently using a large metal window frame (5' x 8' picture window) as the antenna. I used alligator clips directly from the KX3 to two spots on the frame, experimenting with spacing. This is not described in the literature, but it worked. The ATU tuned up the window frame to ~1.0:1 on 20-6 meters.

OK; thanks for that; I stand corrected---to a large degree---turns out that their meanings actually overlap depending on the context in which each word is used (although I was brought up by a newspaper editor dad who explained things like this to me at an early age).
 
While foundering at sea means filling with water and sinking floundering can mean almost the same thing; to flail about helplessly or be lost in a manner of speaking---as you so rightly point out.  Down here on the Gulf Coast I happen to enjoy eating a lot of grilled flounder, too---but sometimes I have to eat crow as it were...
 
I suspect because the words are so often confused that their meanings have shifted together over the years an thank you for correcting me (and my apologies to the OP for my error/minor rant).  QRT on the OT subject, too

A few years ago I took a cue from a usenet posting by Walt, W2DU, that
stated that the 102 foot doublet of the G5RV is a good antenna on 80m
when fed with twin/window lead and a tuner as it is 3/8 of a wavelength
on that band.  I carried it further and have a 204 foot doublet fed with
450 ohm window lead and a Palstar AT1500DT tuner and the apex around 40
feet above ground level and the ends around 20 feet..  It may or may not
work with the K3's internal tuner as I've not tried feeding it with
coax.  It works very well for me on 160m, 80m, and 40m.  At the moment I
am also feeding it on the higher bands until I get dedicated wires up
for those bands.

As I understand it, the 3/8 wavelength on the lowest band avoids
feeding it at the voltage loop so matching is easier.  Having a 3/4
wavelength 80m and 1.5 wavelengths on 40m also matches easily in my
experience.

RFI at higher power, drop back to a lower level.

102 feet.

There is nothing magic about 102 feet if you feed it with open-wire line.
Having a decent match at the feed point doesn't mean squat because
feed-point impedance is transformed by the feed line and what you get at
the transmitter end won't be the same as at the feed point unless feed-line
length is an even multiple of a half wavelength.

What IS important is the total length of one half of your dipole plus your
open-wire feed.

For whatever frequency/frequencies you want an easy match on, make half of
your dipole plus feed length as close to an odd multiple of a quarter
wavelength as you can.

This can be problematic if you want to operate on multiple bands. Don't
despair--it's not that hard. You can adjust flat-top length or feed-line
length or both to get something you can match on all your bands of
interest.

Bottom line. Your ability to match is affected by both dipole length and
(open-wire) feed-line length.

I found a way to trick the P3 into setting the frequency to the left edge
for USB, Data, RTTY and CW or right for lower sideband.  It is a combination
of K3 and P3 commands which are mode dependent.  I wanted to be able to look
at a signal with a narrowed span with the carrier at the edge.  I use DXLabs
Commander to execute the macro commands.   It ends up tickling the P3 to do
what you want.  I included examples for USB and LSB.  I have versions for
CW, Data and RTTY as well. I know it looks silly from a command standpoint
but it works pretty repeatably.  I use a series of ifmode statements in
Commander to pick the correct macro commands based on mode {not shown}.  The
result when the commands execute is the Carrier goes to the edge and then
the span is set 4.5Khz so you can look at the signal your listening to
across the full display.  

Try this for USB:  [The wait is a delay that is specific to Commander's
macro language]
'dn4;
'#CTF+00000000000;
'#spn000020;
'#fxt0;
<wait>
<wait>
'up5;
'#fxt1;
<wait>
<wait>
'#spn000045;
'dn5;
'up4;

LSB I use this:

'up4;
'#CTF+00000000000;
'#spn000020;
'#fxt0;
<wait>
<wait>
'dn5;
'#fxt1;
<wait>
<wait>
'#spn000045;

Hope this helps.  I use it all the time with commander.

Hi All,

When in Key West I have little space for antennas. I built a simple Off
Center Fed 40M Windom [ 67/33 or about 44' & 22' ]. The long element is a
15' off of the ground while the short element that is not much higher goes
up to the peak of my QTH and back down to the other side of my deck.

 

My K2/100 - KAT100 generally runs 75W & I've had great success with this
antenna on every band 40-10. For 80M and 160M I alligator clip an 8' piece
of wire from the end of the short element to my gutter system with provides
another 80' of metal to the antenna. Do I burn up 160 & 80, not big time no
but, I make contacts on both bands.

 

In addition, if you ask me what I do for a ground: It's a 40' piece of #14
wire connected to a 2' piece of copper ground rod. Key West is a rock and
it's tough to get down any further. 

 

Is my 40M Windom Gutter/Rube Goldberg Contraption a dummy load, no! I have
the K2ZR/4 contest wallpaper and logs full of contacts to prove it. 

It 'taint perfect but you do what ya gotta do. And, if the bands are in
lousey shape I ride my bike 5 minutes to my shady spot at Fort Zachory
Taylor Beach and play some tunes on my Taylor Big Baby guitar. Life is good!

Oops,

 

Jim

I use two antennas here at my place. 

For 80 and 160 I use a 170 foot long wire running from just over my feed
line entry to a point 40 ft below a branch on a 75 ft pine, up to to the
branch and over to another tree ( kinda like a "Z"). This is fed to an "L
Match" made from a section of coil and a variable capacitor for 80 and I add
an additional fixed cap for 160. 

 

For higher bands I have a 40-20-10 meter "fan" dipole that my K-Line (& my
KX3-Line") will tune on 40-20-17-15-12-10-6 meters. Many will say "it can't
work" but please don't tell my radios!  The Elecraft tuners can tune
anything!  

I once worked a friend who'd just moved and was using a "GutterTron" ant in
the CQWW. Yeah, the gutter and downspout fed against a ground-rod. 

 

Another friend loaded up the liner in his chimney, called a GutterTron. 

 

Have fun. Try anything. It just might work. You can make a lot of antennas
from a $45.00 spool of THHN and plastic "cutting" board from Walmart. About
2/3rds the price of a G5RV.

  Been there, done that one too.  Hamfest in Concordia, KS back in the 
early 80's just after I retired from the Army.  Used an old Ten-Tec 
Argonaut and loaded the entire gutter system at the motel the hamfest 
was held at.  There was so much corrosion in the joints that even the 5 
watt Argonaut wiped out TV reception throughout the whole motel.  Worked 
a whole bunch of stations on 20 meters too.  Good thing they never 
figured out where the problem was coming from - LOL!

There is an incredible range of characteristics to unwanted "signals" 
that we loosely call noise.

The K3 has an array of tools to fight noise, and sometimes they work 
well in concert and sometimes better alone.

There is an IF blanker with adjustable threshold and pulse width - but 
some impulse noise ay wider than the widest available setting and this 
is likely to include lightning-based pulses.

There is also a DSP-based "IF" noise blanker.

There is a noise reduction, or denoiser function available with a wide 
range of settings.

AGC settings can also affect the operation, and apparent effectiveness, 
of the DSP-based noise reduction and to some degree the noise blanker.  
There is a pulse function in the AGC system that you can enable or disable,

These settings may all interact to some degree.

As the station operator, you have a complete communications system to 
manage: antenna, feedline, QTH, desired path, time of day and so forth.  
The radio is one component of the system.  The K3 offers a range of 
tools for you to use, but in the end there is unlikely to be a "magic" 
setting that works for everything. If there were, we would have set that 
at the factory for you (and probably removed the settable "knobs" for 
you to adjust)!

I suggest that if you are having a severe noise problem, you experiment 
with the various settings - including AGC threshold and slope and PRE 
and ATT settings as part of the tool set - and note which work best for 
you in your system and under which types of noise and mode(s) of operation.

You won't hurt anything, and you may learn a lot.

And, yes, some radios may work better than others with some types of 
noise under some circumstances.

I find the noise reduction NR in KX3 is much easier to use and gives a better effect than NR in K3.? I just wonder whether other elecrafters feel the same.

Regrettably, none of the 4 x 8 =32 settings in the NR of K3 gives the performance in par with the NR in KX3.

My observations only relate to SSB operation.? I always try to find a way to effectively use the NR in K3 but failed.

Perhaps, experts here could guide me to the right way to use the NR in K3.

This may be the result of the DSP used in the KX3, which was designed 
several years after the K3. Moore's Law, and so on.

My neighbor, W6GJB, feels that the KX3 decoders for RTTY and PSK work 
better than the K3 decoders. I don't have enough experience to offer a 
judgement call.

KX3'NR is simple to use and gives immediatly good results. K3's NR is more
difficult to use but, with low settings like 1-1 or 5-1/5-2/5-3, I find it
excellent and it compares favourably (equivalent) with the KX3 and other
brands or rigs using mid-range settings. The more agressive settings are
very special to use...  

I tested a lot of NR with various brands. Overall, none is better than the
others but for some particular situation, one brand may give better results.
This may explain this particular result with the static noises.

You might consider an off-centre-fed dipole with appropriate balun and 
choke.  A dual core balun that gives good cancellation of common mode 
currents at the feed point is essential and some folks add another choke on 
the ground with ground spike on the house side to drain off residual cmc. 
If you are particularly prone to local noise pickup on your long runs of 
coax, then another choke at the entry to your house is a good move.

Coverage of 160 to 6 is possible but the baluns and chokes need attention to 
cover that range, especially if suspended and running power unless sturdily 
supported.  Inverted V is easiest.  You might not get all the coverage you 
want in one wire but you can join another ocfd onto the original to get more 
coverage on difficult bands.

The ocfd gives your matching unit an easier time, ie reduced losses. 
Running your radio without a linear means you can have a lightweight aerial 
with small balun on fibreglass pole.

These gents have done a huge amount of work: http://hamwaves.com/cl-ocfd/

Is there any documentation? All I could find was the firmware, and since
I am anxiously awaiting the delivery of my KX3 it would give me
something to do to pass the time.

Not if you're going to run power. An off center fed antenna generates 
high common mode voltage, which will fry even the best choke when 
running power. I wouldn't consider such an antenna at greater than 100W.

MCU 2.11 / DSP 1.30, 6-26-2014

* FAST MESSAGE PLAY: A long-hold of MSG (~3 sec) puts the KX3 into FAST PLAY mode. In this mode, the BAND+, BAND-, and FREQ_ENT switches can be used to play/repeat messages 1, 2, and 3 immediately, without the need to first tap MSG. To turn off fast play, hold MSG for ~3 seconds again, or turn the KX3 off and back on. Notes: (1) In voice modes (using the built-in DVR), only messages 1 and 2 are available, corresponding to BAND+ and BAND- in fast-play. (2) At present, message chaining is only available in CW modes (with both normal and fast-play).

Wayne,

As suggested in my recent post it would be very useful if the KX3 user himself could decide which of the 3 switches he would donate for fast play!?

For a year or more now I have been using a simple near but not resonant 40m
vertical delta loop with the peak at about 33feet and fed with a random
length of ladder line to a remote auto tuner contained in a water resistant
box. Tuner is a MFJ 993b I think.
Tunes well 6m through 160m. Not very great performance on 80 and 160m but
have made some contacts. I really only use 80m for the QRP fox hunts with
some success.  Easy to use except the tuner likes 15-20watts for fast
tuning. Hunts a little using 5w on some bands.

You can see my setup on my qrz page.

I tried a 40M OCFD for a while. I gave up on it and went back to a centre 
fed dipole instead.

Even on 40M it didn't seem very good and I was plagued with RF getting into 
PCs and them shutting down or periferals stopping working.  Plus, despite 
the hype, it didn't really seem to work well on other bands.  The Antenna 
analyser was very dismissive, showing resonances outside of the Amateur 
bands and, on some that it was supposed to work on, no sign of any resonance 
at all.

Lots of guys have good results with OCF dipoles all over the world.

I run a weekly nationwide net for a Brand X radio model using a 40-6 
meter OCF dipole.   I am the loud signal and I hear all and they all 
hear me.  Of course it helps I am in the Midwest, but still, I run 700 
watts into it and NO CMC or other problems.  I can run more power, but 
don't because that is enough to get the job done.   Power is not an 
issue on my OCF dipole.

Best advice I ever received on OCF Dipoles comes from a guy who tested 
several OCF dipoles for common mode noise, and then found the right type 
of balun/choke to use.   IT DOES make a difference how you build and 
deploy it.   If you run the feed line closer to one side than the other, 
you get CMC.   If you use the wrong balun, you get CMC.

See here:  http://www.dj0ip.de/cmc-test/

Using a proper DUAL Core balun - where the transformer is wound on a 
separate toroid from the choke wound on another toriod - it works fine 
and you have no CMC noise issue.

Stop by my shack and have a listen.  CMC "can" be a problem if you allow 
it to be, but not if you pay attention to what you are doing.  Again, 
don't believe me... stop by the shack or join my net some Wed evening 
and see.   (We don't care what brand rig you own - its is ham radio and 
it is all good)

Just MY take.  This antenna works better than the AlphaDelta and home 
brew fan dipoles I used to use... (although I cannot explain why the 
others did not work as well, they should have...but who knows what they 
were coupling with in my crowded little lot.)

Happy days.

I have always found the the OCF antennas require a sufficient amount of feedline to mask the weird impedances it has.? I have successfully used 135 foot 33% offset fed 4:1 balun with W1JR choke and >100 feet of coax necessary.? I tried to use 22 feet and it was a total loss.? All with <100 watts of course like Jim suggests.? The added length does not add enough loss to account for the change.?

I was using QRP, 3 Watts from the KX3, and I tend to use less than 5W CW on most bands.

Even on receive it performed poorly, which is why I wnt back to a dipole.

  Off center fed dipoles, Windoms and end fed half waves are primarily low power if not QRP antennas where you can do poorly with any antenna.  They are prone to arcing, heating and RF where you don't want it.  You are better off with conventional low radiation resistance antennas if you plan to use 100 watts or higher.  The search for an antenna that will make QRP sound like a kilowatt is futile.  The only way to do that is to have excellent conditions and infinite patience which will make anything sort of work.

Jim, 
What you say can be correct. However, this need not happen all the time. When common mode issues arise one of the problems is that the wrong type of balun was chosen. Voltage baluns suffer when the VSWR gets too high. What you really need to use on these types of antennas is a current type balun. They have less of a problem than do the voltage type. 

I use a Carolina Windom here. That means I use a voltage type balun at the feed point, deliberately causing radiation from the shield of the vertical section of feed coax. 18 feet bellow the antenna feed point I place a 1:1 current balun, an RF choke, to prevent common mode problems. I have not had problems with common mode currents with this arrangement, and it will work at higher powers than the 100 Watts I normally use so long as the baluns and coax are rated for the power level you plan to run. 

73, 
Barry 
K3NDM

Not if you're going to run power. An off center fed antenna generates 
high common mode voltage, which will fry even the best choke when 
running power. I wouldn't consider such an antenna at greater than 100W.

In QRP contesting, I do a lot of band switching. If I understand FAST PLAY
correctly, having it on the band switch buttons is a big waste of time. It
would take a good 10-15 seconds to de-activate FP, switch bands, re-activate
FP. On the other hand, I virtually NEVER use the PRE/NR(1), ATTN/NB(2), and
APF/NTCH(3) buttons in contesting or otherwise. Personally I would much
sooner see these three buttons used for FP. I also like the idea of Heinz
HB9BCB about allowing the user to choose the buttons. What do other
contesters think?

An end-fed half wave inverted L (EFHWL) done properly works very well. It
needs to be tuned at the base of the wire against ground.

An EFHWL for 80m is an excellent antenna that has no nulls and has
vertically polarized low angle radiation equal to a decent 1/4 wave
vertical. The horizontal wire fills in the general pattern to a hemisphere
with a broad and mild null in the direction of the horizontal pull. It is
an ideal all-distance contest antenna, because there are no holes in
coverage in any direction or elevation.

I have used this antenna at 1.5 kW off and on across 50 years with
excellent results. The current max is at the bend, with a high resistance
feed at the ground, making the effective series resistance of the grounding
system of no consequence. Even a completely pathetic 100 ohm ground at the
base does little damage against a 1000-2000-3000 ohm feedpoint for the
wire.

It IS uncommon and requires tuning at the base of the antenna, and that
network requires components usually found in the output tuning networks of
tube based QRO amplifiers.  You can't feed the base of the antenna directly
from coax without a tuner, and you can't buy the tuner off the shelf
anywhere.

With some DPST relays, coil stock and a single well-chosen fixed value QRO
transmit capacitor, the antenna + tuning mechanism can cover the entire
3.5-4 ham band with less than 1.5:1 SWR anywhere.

With some further work in the tuning mechanism, and attention to a proper
160m counterpoise, the wire will work well on 160-80-40-30 with distance
from any tower(s).

In my experience with that over the years, the EFHWL always beat an 80
dipole or inverted vee for DX and was as good as or beat dipole and vee for
local and mid range. A 4-square would beat the EFHWL for DX.

For a year or more now I have been using a simple, near to 40m vertical
delta loop with the peak at about 33 feet and fed with a random length of
ladder lineby a remote auto tuner and BL2 4:1 Balun contained in a water
resistant box below the mast. Tuner is a MFJ 993b I think. Tunes well 6m
through 160m. Not very great performance on 80 and 160m but have made some
contacts. I really only use 80m for the QRP fox hunts with some success.
Easy to use except the tuner likes 20watts for fast tuning. SSometimes I
have to tune twice. Once to allow the KAT2 to lower the swr and allow full
output. Then the remote tunes. Then I retune or bypass the K2 tuner.  Hunts
a little a little while using 5w on some bands. Many evenings I will set
the K2 on a table under the K2 using its internal tuner and BL2 to directly
feed the ladder line and loop which is fed to a lower corner. K2  tunes
10-80m easily.

You can see my setup on my qrz page.

Hi Guy

same thing here I was going to use it on 160 but really like 75
makes a good DX antenna and when the band is open I have
no problems breaking pileups,,, up 40 Ft and out ? Horz
works OK on all other harmonic related bands ,,, did run some tests with 
a station 30 miles from me. I used to use a tuner at the base but I find
the
HB antenna tuner in the shack works well ,,,So what the heck ,,, Use a
series of ferrites on the
coax feed and run the feed about 50 Ft through the basement to the shack
not a QRP antenna ? use a Heath amp drive it wit a K3
bottom line
put up some wire and get on the air

Wayne,

That is awesome! Another reason I went with the KX3, upgradable
firmware. While most rigs can upgrade their firmware no one is going
outside the norm.

Now just time to decide if I should sell the TS-2000 LE to get the
KXPA100 :)

Thanks for the description. I look forward to getting it loaded up.

Good Evening,
    It has been almost a week since it last rained.  I have seen the sun 
for at least a few hours each day.  Maybe, just maybe, the dry season 
has arrived.  I won't hold my breath though.  There are some mosquitoes 
now but they are in no way as large as those I once met in Arkadelphia.  
They could syphon your blood in seconds flat.  These would require many 
hours to do the same.

    The sun is quite spotted and due for some flare activity. Hopefully 
conditions will be better than they were last weekend. While I gathered 
the information of over 500 stations I was only able to get 120 of them 
to reply.  Oh well, it was fun.  Now is the season to pull down last 
year's antennas and build new ones. Hook up the guy lines to the F-250, 
put it into 4WD low and try not to get a branch through the cab.  After 
only a month the lines heal into the bark of the tree necessitating the 
aforementioned procedure.

Please join us tomorrow.

This e-mail may reach you via several routes and/or mailing lists. I
apologize
if you receive multiple copies as I try to reach everyone.

Some of you are aware that a few weeks ago a small cancer was discovered
on the interior wall of my uterus.  Although all the women in my family
going
back several generations have suffered from breast cancer, I though that at
age 75 I'd "made it" OK.

The matter was addressed quickly and I had a complete hysterectomy within
just a few days.  The good news is that my oncologists tell me the small
cancer
had not "escaped" from within the uterus and that I'm "cancer free".

I've had CT scans, X-rays and other tests and the oncologists tell me they
find
no sign of any remaining cancer.  However, they suggest that I have a
series
of chemotherapy treatments as a "preventative" matter.

Rather than receive the treatments on the usual three-week or monthly basis
I've elected to go for treatment once a week.  This means that I receive
smaller
infusions of the drugs each time with less impact on my body.  It's still
debilitating,
however. I've now had four treatments and they will continue for a total of
18.

My treatment is being done at a relatively new cancer center at Community
Hospital in Missoula, about 110 miles from here.  I couldn't ask for better
care.
A treatment takes 3 - 4 hours while in a large recliner chair.  No-cost
snacks
and drinks are provided, and there are free cancer-coping items like wigs
... I'm
starting to lose my hair ... hats, scarves, etc. available, courtesy of the
American
Cancer Society.

All this has severely impacted my sewing on case and cover orders, of
course.
It's looking like I'll be able to sew a couple of days a week, and I'll be
turning out
your orders as quickly as I can.  Your understanding has been heart-warming.
Thank you!

It's been my practice to acknowledge your order(s) and place them in my
queue
and then notify you when I'm about to start your order so you can make
payment.
There -are- several who have went ahead and made payment.  If you want to
confirm that all is well with your order, don't hesitate to inquire.  Ken
will be helping
with the order tracking and correspondence.

If you don't wish to wait for me to fill your order, feel free to
cancel.  FWIW, I -don't-
plan to quit my little business, but if you want to cancel your order, I
will certainly
understand.

The problem, according to my own experience, is that the ground in
intermittent. Each paddle arm is the ground that makes contact with each
standoff. Without a good grounding, the contact action between the set screw
and the standoff is sometimes hit or miss. The reason the ground is
occasionally weak is because the contact with ground by each keying paddle
is designed to be via the pivot pins of each paddle arm. They are
independent and sometimes intermittent grounding occurs. This results is
missed dots or dashes (dits/dahs) being keyed. There are some solutions
outlined on the web whereby one does a little soldering of two small wires
to ground and then screw down the opposite ends of said wire under the heads
of each countersunk screw head on each respective paddle arm. (These screw
heads are the spring retainer screws.)

I developed another reliable solution whereby no soldering is required. (I
am good at soldering but the miniaturization of the solder pads here are
very delicate. I feel sure warranty issues come to mind as well. ) A great
alternative is to provide backup grounding. 

To do so, 

1. Disassemble as if changing springs.

2. The spring is coated for durability and anti-corrosion. So, on each end,
place the spring opening (each end alternatively) on a micro file (or very
fine emory board) and remove just the coating on the ends that contact the
arms.

3. Delicately, use a small screwdriver or tool to remove the paint where the
spring contacts each arm. Take your time. The paint is durable. Just remove
an amount about the size of a lock washer. This will, in effect connect each
paddle arm together.

4. When disassembling the key, you removed three allen screws. The heads of
these screws fit into a recessed hole. At the bottom of that recess, you
will need to remove the paint there as well. You need only do one but I did
all three to be sure. 

5. Reassemble the keyer.

This mod resulted in 100% keying. The original reliability was dependent on
the pivot arms of each paddle independently. This mod increases the
reliability by transferring a good ground (via the spring) over to the arm
that may be intermittently ungrounded. This method is still statistically
less than 100% over time, but whereas I was getting keying errors regularly,
they have completely disappeared. 

Happy keying.

Hello Bill,

> standoff.

Well I recognized this problem too and ended up putting an soldering 
eyelet under each spring retainer screw. I soldered small bus wire to 
the eyelets and soldered the other ends directly to the GND pad of the 
4-pin connector.

This seems to work very good whereas clearing the ATU memories prevents 
the keyer from interrupting your transmission when the ATU is recalling 
old memory settings and you have used another antenna before.

Anyway...I did a lot of QSOs with this modification and still have 
problems here and there. It seems like the key doesn't like me! :) Some 
days I need to correct every few words and other days the key is working 
fine.

I have no such problems when using my old Ten Tec model 604 key with 
built-in keyer. So it should not be my keying itself...

Anyhow...I am living with that issue at the moment. Maybe I will upgrade 
to a Begali Adventure but at the moment the modified stock key is not 
bothering me too much to pay another $350 for a new key.

Anyhow, the KXPD3 is still great bang for the buck and fits nicely to 
the rig.

Subject: [Elecraft] Serial Port Question...
Message-ID: <1404681349.6248.43.camel@nostromo.NK7Z>

I have a question about serial ports and the K3...  first let me set the
stage for the failures...

Setup:
I have a K3, (two RX), and a P3, (SVGA), connected to my Windows
machine, which is running a fully updated and patched version of XP,
using a RS-232 serial cable, and the built in serial card, at 38K.  It
is a Dell machine.

Test Bed:
If I use HRD, latest free version, to move the K3 main tuning dial
around, using the mouse wheel to increment the 100 Hz digit, I have zero
issues, the movement is snappy, and quick, there is no lag between my
end of motion in moving the mouse wheel and the K3 arriving at its end
of motion in changing frequency.  I.e. When I stop moving the mouse
wheel, the K3 is on frequency.  Exactly as it was on my Pro III.  Both
under HRD, AND MixW

Now, if I switch to MixW, again latest version etc., same com port, same
comport speed, in fact same settings as far as I can see for everything,
I get a very discernible lag in the move event concluding.  It acts like
the K3 frequency is rate limited in how fast it can slew in frequency,
only when using MixW, and not when using HRD.  Exact same setup, and no
issues on the Pro III I used to have.

I also have a very minor programming issue where by the the K3 fails to
fully program every channel using the K3 frequency management
software...  I get the failed timeout error now and then...

All of this points directly to a serial port issue...  However...

I have run this computer on many other pieces of hardware, (including a
Pro III, and Pro II), and had zero issues along this line.  I have run
the same hardware, and the same software, configured exactly the same on
the Pro III, and a Pro II, with zero issues.  I.e. I do not have the lag
issue on the Pro III, or Pro II. but do on the K3...  Same hardware,
same configuration, and same software, same cables, etc...

No other issues with serial ports of any kind with the computer...  All
running under stock windows XP fully updated.  

Question:
Why does the K3 feel like the speed with which it changes frequency is
rate limited only under MixW, and not under HRD.

I am at a loss, and looking for suggestions here...

I've observed metering fluctuations as well.

Equipment:  K-line.
ALC off
Operating mode:  Amplifier output direct to dummy load or antenna -- same
observed behavior with either load.
Constant power, e.g. CW
All cable verified as good.

1.  KPA500 LED Power Indication -- In standby or operate, the last power LED
flickers.  In Standby, at any drive power, the last power LED flickers.  In
Operate, at any drive power, the last power LED always flickers.  
2.  KPA500 SWR metering -- always stable
3.  KPA LCD Analog power metering -- In standby, the meter is stable; i.e.,
with 100 watts drive -- indicates 100 watts.  In operate, at any power
level, the analog meter fluctuates.  The amount of the fluctuation is
difficult to discern since it varies rapidly.
4.  Peak Hold -- when in Peak Hold mode, the last power LED's are stable,
but occasionally in Operate, the next to last LED flickers.

K3 metering stable.

When monitoring the K3 or KPA power output on Elecraft W2, the power
indication is stable.

Question:  Is this a KPA500 metering anomaly?  Or is this an indication of a
power supply noise problem, e.g., power supply hum?  No one has complained
of hum.  I did get one and only one comment from a discerning individual
that there was audio break-up at peak modulation.

I've not yet rigged up a scope on the PS, pending comment from others.

What is the command rate of MixW?  Each program has it's own polling or
command rate and they can differ by a substantial amount.

Addendum:

KPA500 LCD voltage metering also fluctuates rapidly when in Operate mode and
under load.  Nominal voltage 60 volts at 500 watts output.  Fluctuation
amplitude cannot be discerned since variations are rapid.

Hi
One way to tell what is going on is to use a serial port monitor. Eltima has on that has a free trial.?
You install it, start it and then select the comport you wish to monitor. Select terminal mode.?
Then start the software you wish to monitor. ?Look at the commands before and after the software issues an FA00014200000 for example (that is a command to tune to 14.2 mhz. Also see if you see some kind of delay. Some of the other modes in the serial port monitor, can give timestamps too which might be useful.?
Send an excerpt if you can do this and may be we can see something

No, that's *not* what I was asking.

How many times per second do the particular programs send an "up
100 Hz" command to the radio?  How quickly can they send commands?

Some programs store the "move up" or "move down" commands and pace
them out one every 100 ms or one every 250 ms or one every 500 ms.
The slower the program parcels out the commands, the greater the
lag.

73,

Hi Joe,
OK I understand now, thanks for clearing that up... I will see if I can
locate that info in either program.  I do have a serial capture from
both programs, and they do look vastly different...  I am a bit reticent
to put them up here, due to size...

Message-ID: <CAN75_nhQgKsyXRzP9rQKdK2pvkFQtgnqNckVw4gO3foxTE9pNg@mail.gmail.com>

I ran a quick test on my KX3/KXPA100 output using the output power
calibration and the results don't really make sense to me.  This was on 40m
into a dummy load:

Using the KXPA100's cal number (ALC A2.5), the max output was 90 watts with
the KX3 set to 110W output.  The 90W measurement was from the KXPA Utility
software.

Next, I ran the power output calibration and the cal factor changed pretty
considerably to (ALC T4.4) but when I set the KX3 to 110W and hit Tune, it
again put out 90W.  Based on the difference between the two calibration
factors, I assumed the output power would increase when using the KX3's cal
factor but it was identical so the output power cal did not appear to have
any effect.

This was on an Astron RS-35M set to 14.0V output and both units are using
the latest beta firmware.  The KXPA100 doesn't have a tuner and is set to
AUTO/OUT attenuation.

(And anybody quoting me an answer about fractions of an S-unit will get
ignored.  That's not the nature of the question).

Have a new K3 here in the shack; my first Elecraft and the  finest HF rig 
I've ever used!  Have been learning it for several weeks,  and just have one 
small issue which I hope someone can help me straighten  out: when I try to 
save the rigs configuration using the K3 Utility  program, the program gets 
through about 80% of the save and won't go  any further.  The program stops 
operating at that point, and I have to  close it with Task Manager because 
*Cancel* has no effect.
 
Wondering if anyone has had this problem and could offer a  solution.

US news tonight said "cell phones," but who knows, news anchors and the 
guys on the street often can't tell the difference between a phone and 
an HT.

We're traveling a bit this month, I'm not taking any of my Elecraft 
radios.  Real reason is that I won't have time to use any, but I already 
get severely hassled by TSA with the leg braces I use and the scrap 
metal I carry, and I really don't want to be explaining amateur radio to 
some trainee.  And, I always get the trainee. :-)))

I was curious tonight, why would being able to turn your phone on 
[probably already is on], indicate that there wasn't a bomb inside?  To 
this point, I've never had a TSA question about any radio gear ... 
usually K2 or KX1, and an HT.  The HT went through the x-ray twice, the 
K2 was blocking it the first time.

Subject: [Elecraft] K3 and KRC2 for controlling 12VDC
Message-ID: <53BA1820.6020104@comcast.net>

I have pretty much done an thorough search on this topic and have 
concluded it cannot be done, but I thought I would throw it out here anyway.

I believe that the outputs on the KRC2 on strictly controlled by band 
information which it receives.  I was wondering if there was a way to 
send RX antenna status to the KRC2 which would close an output to send 
12VDC to my active RX antenna and another to activate 12VDC to the 
preamp for the RX ant when I chose.

My thought was along the lines of the DVK messages which can be 
activated via the keyboard when using Writelog or other contest 
programs.  I was hoping to send a command via the keyboard to activate 
the RX ant on the K3 and at the same time send the required 12vdc to the 
RX antenna via an output on the KRC2 and the same for the preamp if I 
want it on/off.

I hope this is clearer than mud.

Rich,

If the RX antenna is the only thing you want to control with the KRC2, 
the answer is easy - just use the KRC2 configurator application to 
select the outputs for the bands you desire.
The High level outputs can provide the source of 12 volts (up to the 
current limit of the drivers).

I am not sure what that has to do with the DVK messages - I do not see 
how those can be related.

73,
Don W3FPR

Dave sent me a log of the serial port activity from MixW, showing the steady state and the situation when he is tuning using the software and  the K3.

The steady state polling form MixW to the K3 consists of the commands:
IF; and FB;
So basically it is polling the radio for the transceiver information (IF) which includes info such as the VFO A frequency and other items and for the frequency of VFO B (FB;).
It continues to do this indefinitely.

However, when the frequency is changed in the software, then the programs issues the following command each time the frequency is changed:

FR0; FT0; FA00021014700

and then it continues to send these commands for as long as the frequency is requested to change.

In the example I was sent, dave changed the frequency from 21014700 until 21009100.  During this time, 150 commands were issued to the K3 over a period of 5 seconds. When this was complete, it took an additional three seconds before a response  was returned to a subsequent IF; command.

So, what does this indicate:  First of all during the time that the frequency was being changed, no commands occurred to read the current frequency of the radio.  That in itself may not necessarily be bad IF the program updates the VFO display in the program each time.  Of course at the end of the update, if the radio did not keep up, the final frequency will change as soon as the new IF; command arrives.  

Now, since it took a full 3 seconds after the sequence of frequency changes, it is pretty clear that the command rate of 100ms is too short.  The program had to wait for all 150 commands to complete before it could get it?s updated frequency.

So, first thing is to increase the command rate in MixW to something higher.  experimentation might be required.  Ultimately though, if the display is not updated with the frequency during the changes, it might seem that the software can not keep up.

Second, I would look in the setup of MixW and see  if there is an option to enable the AI1 command (AUTOINF).  If not, the software may actually respond to it, but it should be documented.  You can try to set CONFIG:AUTOINF = AUTO 1 in the tech mode entries but this can have consequences for software than does not support this.

The bottom line is you are polling too quick, but if the software does not update the display during the frequency updates you are out of luck.
No need to look at HRD, it ?works?.
Hope this helps.

I've decided to sell my new and almost unused K3 (S/N 7850) and P3 w/SVGA
package (both factory assembled 11/2013). K3 re-inspected under warranty
1/2014, and full calibration and alignment. Less than 50 hrs use. 

Both have been in the single box factory packaging since January. Physical
and electrical condition as received new. Smoke free environment and no
portable or mobile ops. Fully filtered dual receivers, no internal tuner,
standard TCXO, most options. 

Somebody who loves the K3/P3 needs to give them a good shack to operate in.
Have $5500 invested. Sale documentation, warranty report, and pictures on
request. Good in QRZ. 

Will only sell as package. No Trades or other offers please.

73, Gary NL7Y

Tom,

Thank you for looking that over, it would have taken me a day or more as
I have not looked at serial output for a decade or more... :)

I will investigate MixW and see what I can find...  If I find a fix, I
will post it here.

	100% green power
Message-ID: <00601EBE-6A2A-4E68-81DF-F0C1620A814C@elecraft.com>

Hi all,

I wanted to acknowledge what is, to the best of my knowledge, a unique feat by Don Bush, WA2TPU. He has achieved DXCC (over 100 countries worked) on every ham band from 160-6 meters, excluding 60 meters, running 5 watts or less for all QSOs. He used a mix of modes, and 100% natural power (off the grid, in other words). He used a variety of transceivers. 

Don was issued the only 10-band QRP DXCC certificate in the history of QRP ARCI on April 4th, 2014. (In fact he was also issued the only 8- and 9-band QRP DXCC certificates a couple of months earlier. I'm not sure if 11 bands is even possible, but I'm sure he'd go for it :)

It takes a lot of persistence to pull this off. Don did it over about 30 years, using various hand-built log-periodics, Yagis, quads, delta loops, Sterba curtains, phased verticals, rhombics, etc. I'm hoping to see his station someday.

Thanks, Don, for giving a lot of us something to aspire to!

That is MUCH, MUCH easier from W2 than from W6. I have 131 countries 
confirmed on 160M with legal limit in 8 years and great antennas. Even 
with a 550 ft Beverage pointed that way, I haven't even HEARD EU on 160M 
for nearly 3 years.

Don,
Apologies for the slow response: I'm doing a lot of business travel right now.
Yes, you're right, I didn't provide much information. Sorry about that.

I managed to squeeze an hour in yesterday, and measured the voltages in the affected area. RF Board U4 is OK, except that CLK and DIN are both inverted. I hadn't noticed this when tracing with a scope. CLK (pin 7) is at 5.03V, whereas DIN (pin 5) is at 0V. They should be at the opposite ends.

Going to the Control Board confirms these readings on U7, but that's when I ran out of time. I did a visual inspection of U7 and it looks OK. I may get an hour this evening, so I'll check U6 and U8.

One of the problems with the paddle is that the arms can move up and down to much.  Sometimes my contacts don't touch correctly unless I force the dit arm down.  A better job of drilling and machineing of the holes that the arms pivit in would fix the problem.  My dit arm has over 150 thousense of an inch of up and down movement.

He used a mix of modes, and 100% natural power (off the grid, in other words). He used a variety of transceivers.

Yes the IC element is preferred for the KX3 as it has capability of providing the bias for the electret element.  Check the manual for setup instructions for microphones.

Hi Jay,

The most common explanation for this problem is incorrect antenna assignment
on that band. The K3 remembers your selection per band so it is possible
that one band might have the wrong assignment.

In a like manner other parameters are remembered per band such as filters,
NR, NB, ATT or PRE, etc..

73,
Mike K2MK

I think the ends of the pins are different. Make sure both are pointed in same direction.

Chris,
     You will need the IC version. It uses the same element type that 
the KX3 wants to see. I use the IC version here for contesting. I did do 
an adjustment to the equalizer and compressor settings and got very good 
audio reports for the efforts.

Also make sure your (contest-logging?) software is not causing the problem.
I had a spell, when for reasons I don't completely understand, SUB wasn't
working on forty meters. By chance I disconnected N1MM, which was in SO2V
configuration, and the problem went away. The problem had something to do
with conflict between N1MM and a homebrew external switching scheme.

Theoretically, the K3 could convey RX ANT status to the KRC2 over
AUXBUS, and the KRC2 could drive some outputs based on that, but
(AFAIK) that is not implemented in either firmware.

Rich;

Since you are talking about the K3, I believe your conclusion to be correct, but I would not (yet) rule it out. I don?t believe that the K3 outputs the RxAnt status on the Auxbus. Interestingly, the K2 _does_ output the Rxant status, and the KRC2 can respond to that inout, although it may require a bit of extra work on my part.

I will do some additional research on the code (it has been quite a while?) and let you know if what you want is doable with the K3.

The Kenwood MC60 is an excellent choice. Go look at this previous thread 
for a little further info: 
http://elecraft.365791.n2.nabble.com/K3-Mic-Experimentation-with-Kenwood-MC-60-td6093541.html

A side point - the MC60 is a nice looking mic without being overkill for 
size or price.

Subject: [Elecraft] K3 strange power surging behavior
Message-ID: <1404785366970-7590991.post@n2.nabble.com>

My K3 SN 1502 with MCU 4.83 is exhibiting a strange surge in transmit power
level.   When the rig is keyed in CW with the power set all the way up power
output surges from a high of around 140 (!) watts down to 60 watts and back
in a rapid fashion.  It is at it's worst on 30 meters shows at least a high
power spike on all bands except 160 and 80 before it settles down to around
100 watts.  If I turn the power down the cycling is much less severe but
there is still a leading spike of around 140 watts.  I have tried reloading
the firmware with no luck.  I have checked all my jumpers and connections
and they are fine and the rig does this even straight into a dummy load.  My
power supply is an Astron RS-35M in great shape.

I should mention that we suffered a lightning strike last Labor Day weekend
that took out my Ten Tec tuner, W2 wattmeter and a few other things but the
K3 was not affected at all and I hope this problem is not some delayed thing
from that strike!

An ideas?  The rig is almost six years old - maybe I need to open it up and
make sure screws are all tight?

Bill,

I cannot assure you that this is not some delayed effect of the 
lightning strike,
However, try doing the TX Gain Calibration before anything else. You may 
want to run it 2 or 3 times if it does not help initially.

If that does not correct it, you will have to contact support for 
further assistance.

I've been thinking about getting the K3, P3 and the amp but with all these problems I keep seeing I hesitate to purchase. I talked to a few owner that love the k3 so perhaps this is only a small group that has problems or do a lot of owners have these problems? I ned to know more before I shell out a lot of hard to dollars.? Any suggestion fellows?

Bill,

I cannot assure you that this is not some delayed effect of the

However, try doing the TX Gain Calibration before anything else. You may 
want to run it 2 or 3 times if it does not help initially.

If that does not correct it, you will have to contact support for 
further assistance.

Ray -

One of the great things about this list is that when a person does have a
problem with an Elecraft product, there are a large number of users willing
to help resolve such issues.  Also, please remember, that for "most" of us,
if our rig is working as we want it to, we are not likely to say anything.

I believe that problems which may show up here, represent a small
percentage of users... and, in many cases it appears to me that the problem
is not with the rig itself, but perhaps a faulty cable, or a parameter that
needs to be adjusted.

I am by no means an expert, but I have had my K3 for a little over three
years now with NO problems at all, and I know a number of other folks whose
experience is more like mine, than like those with problems.  I do have one
friend with a K3 that frustrated him at first because it worked one day,
and not the next.  It turned out that there was NOTHING at all that was
wrong with the rig, but as he was getting used to it, he often pushed
buttons without paying attention to what he was doing, and without
following the manual.  He is 92 years old, and does sometimes get in a
hurry.  In each such case, I was able to put the parameters back where they
needed to be, or tell him on the phone how to do that.  It has now been
several months since he experienced any such problems, and the rig performs
perfectly.

I think if you "pull the trigger" on the K-Line you will be very well
served.  My K3, P3 and KPA500 are, by far, the best I have owned in 57
years.  I know there are a number of fine radios out there.  I was able to
borrow a K3 from a friend, and that clinched it for me.  I have not wished
for anything else since I put the K3 on the air.

I don't weigh in on this list very often, because I am usually just working
DX and chewing the rag with great satisfaction.

What ever you decide, I wish you the best.

There are more than 8,000 K3s out there. What percentage do you think 
are exhibiting problems? The great thing about owning a K3 is this 
forum. If you have a problem, there is a community of owners, including 
numerous representatives from the company that makes the rig, there to 
help you. I'm still looking for the Yaesu or Icom forum in which company 
representatives are there to help you and solicit recommendations for 
new features. If you've heard of such a forum, let me know.

There is a reason that significant numbers of world class contesters and 
DXers own K3s, and I assure you it's not because of reliability issues. 
My suggestion would be for you to understand that in a forum like this, 
people talk about issues they are having. That's kind of the point. The 
difference in owning a K3 or something else is that, because of this 
forum, if you have an issue, you might very well find yourself asking 
the person who designed your rig if there's a way to fix it. I can't 
think of a better reason to spend your hard earned dollars with Elecraft.

Scott, N9AA

Not only that, but the two OWNERS of the company read this list every 
day, and chime in with advice when needed. I've seen one of them, N6KR, 
who's the principal design engineer, work one on one with DX trips to 
solve issues, and I've had more than a few one on one engineering 
conversations with him at hamfests and online. Heck -- we can't even 
correspond with low level flunkies at the JA companies (or Ten Tec), let 
alone the guys who own the place! And both owners are active hams, I've 
worked both of them on the air.

How about this for support?  There will be a bunch of K3s in the 
international WRTC competition in New England next weekend, and Elecraft 
is sending at least one of their best engineers (who was a competitor at 
WRTC in Russia 4 years ago) to support those radios. I know because he's 
my neighbor, K6XX.

I've been an Elecraft owner since 2004, and bought two K3s in 2008. I'm 
very pleased with their support. EVERY radio has issues -- with 
Elecraft, there are much fewer of them, and you can get them fixed!

Thx Eric,

My main question is if the iC mic element is required for the KX3?  Can you use the non-powered Dynamic element in their normal ProSet without any difference in audio quality?

How many K3s are there in a 'bunch', Jim?  The implication would appear 
to suggest that there are likely to be problems requiring a best 
Elecraft engineer to fix them.

And then there's the factory support.  I've worked for small specialist 
UK based broadcast electronics company and also was a project manager 
for a large Japanese company. At both companies we were dealing direct 
with the end user.  The support from the factory is second to none.  
Many UK retailers could look to Elecraft to see how to do it...

Hi Ray
I could conclude that in USA are killing universities judging by the
news I see on TV, but reality is different, there are hundreds of
millions of people living normal healthy lives and peace. This mailing
list accumulates questions and issues, then probably you inbox will be
flooded of questions and issues of less than 0.1% of happy users of
great K3.

I'm another user with K3/P3 working perfectly since 2010 !

The MC-60 does have some known RFI issues.  Evne though I've tamed mine
considerably (see http://highfields-arc.co.uk/repairs/mc60.htm ) it
still will exihibit RFI every now and then on 75m.  So long as I don't
hold the mic in both hands (while leaning back in the chair) everything
seems fine.

I should add that after my OP I got the ERROR TXG which indicates a problem
with bandpass filters.  I have emailed support about this.  I will try the
TX calibration tonight after work.

For the poster expressing concern about the reliability of the K3 - I built
my K3 in August 2008 and it has seen heavy use since.  This is the first
significant problem I have had in nearly six years.

I'll check that out sometime.  I only took it partially apart so that I could understand it.  I only have trouble with dits once in a while, and I am not using C.W. a lot.  I do really appreciate the paddle and the thought that has gone into it.  Mine has been very forgiving and durible.  I like that there are no wires involved to use it.

Ray,

Count the number of problems you see posted here (or in the archives) in 
a month or even a year.  Try not to count those that are requests for 
"how do I do ..." assistance.  I think you should also discount the "my 
shack was hit with a lightning surge" reports as well, but that is up to 
you.

Then consider how many K3s are out there - over 8000 K3s, about 4000 
KX3s, I don't know how many P3s and KPA500s and KAT500s.

I think you will find the percentage of actual failures is quite a small 
percentage.

For many Elecraft owners, this reflector is the first resource when 
'something strange' is encountered.  There are a large number of owners 
who are willing to assist others with their 'problems'.
The second resource is Elecraft support, where quick responsiveness is 
the norm - many have mentioned the high level of support available from 
Elecraft.

Chris,

The answer is YES.  Turn off the mic bias, and you may have to increase 
the mic gain, but the KX3 can handle most microphones with a proper adapter.

Hi,
 I think when reading about "all" the problems, you need to keep in mind that the vast majority of Elecraft owners do NOT experience problems.  Those of us that are not having a problem do not get on the list to mention we are not having problems.

If memory servers me correctly, this "problem" was caused by a nearby lightning strike, so no matter what equipment a person might be running, there would be problems!

I own a couple of K3's, P3, KAT500 tuner, KPA500 amp and am extremely pleased in their performance, using them on an almost daily basis.

I have no vested interest in Elecraft, but truly believe there is no better product on the market.

There are nearly 8,000 K3's out there. And yes, issues come up. But they are not systemic. The K3 is a very flexible radio and can be configured to work to suit the owner/operator. I believe you will be very pleased with it if you choose to buy one. 

All current HF rigs work quite well and each has it's strengths and weaknesses. But I feel the K3 shines above the others in many ways. 

First it is modular. The basic radio is really quite nice and you can do most HF operations with only the basic 10 or 100 watts plus the ATU. This combo is priced near the high end of basic level radios but is a lot of performance for the money. Many users stop here and never need more. 

But you can add just about any feature others have as you need/want them.  You can add everything and still be under the price of some of the other brands deluxe offerings. 

And your radio need never be out of date. The very first K3 can be updated to the latest firmware/hardware at any time (usually by the owner). And as features are added or bugs arise, they are quick to make updates available and easy to install. 

And the company support is second to none. 

And there is this reflector with many users who have been "there" before. It's almost impossible to ask a question that someone hasn't asked before or a problem that hasn't already been solved. 

A K3 isn't just a radio, it's an "experience". 

I have the full "monte" and love it!

Gordon,

Most any unamplified Kenwood microphones will work fine, or Heil 
microphones with the Kenwood adapter.
The Kenwood MC-60 is often mentioned.  The amplified Kenwood 60A version 
will work as long as the amplifier is bypassed.

The difference between the Elecraft mic pinout and Kenwood is that 
Elecraft puts +8 volts on pin 6 and Kenwood puts it on pin 5.

I have to agree. Remember, we generally only hear about the failures - 
not the multitude of successes.

For the most part the questions asked on the reflector are good and the 
replies could be of value to the reflector users if:

1. the replies are on topic
2. the replies are not too lengthy (containing too much theory)
3. the replies are made on the reflector and not sent via email
4. the replies are not made in a hateful manner

My friend and I had similar power surge issue with our brand new K3. Having thoroughly made trouble shooting, we found the cause mostly coming from outside K3 or some glitch on constructing K3. I would recommend to carefully check your entire system including coaxial cable to your antenna system as well as inside K3 especially KPA3 to antenna connector.

Howdy Gang:

I needed a HI Z mike for my TR7 and decided on the MC50....just rewired the plug to be compatible with the TR7 and it works FB.

I also got an MC60A mike for my K3...got an 8 to 4 pin mike adaptor, which I had to re-wire,  and  set bias to OFF on the FP)...the K3 likes it and I get good audio reports.

OK...so why not go one further...I got an MC50 for my Drake T4XC and it works great.

No RFI or any other issues with any of the rigs...maybe I'm just lucky.

The MC50 andMC60A can be switch from LO to HI Z which makes them extremely versatile in terms of old and new rigs they will work with.

 I do really like the ability to remove the mike from its holder and use it like a hand mike.

Funny, I'm 100% CW and QRP except for one weekly sked on SSB with a retired buddy....plus I love to keep the older classic rigs on the air...perhaps since I grew up with them (grin).

My favorite rig hands down is the KX3...simply the ultimate in small, portable QRP gear.

When operating cw, I noticed that when I lock the kx3 in transmit with 
the XMIT switch, there is a carrier bleed-through between keystrokes. 
I've done the TXCRNUL adjustment with a spec-an, and it's way down 
there, but it's noticed and is still strong enough to be annoying 
locally. However, if I use the vox feature to initiate a transmission, 
there is no carrier bleed-through. Is this something that could be

I have used the Heil HM5 desk mic since buying it for my FT-847 in 
1998 (I no longer have that radio).  When I bought the K3 all I 
needed was the Kenwood mic cable to connect the Heil mic to the K3 
(plug n play)!

I know many consider Heil overpriced, but I never have had a signal 
bad report using it.  Doubly so when connected to the K3!  I bought 
the mic with the natural-sounding full frequency response element, 
since I am not a contester.

The K3 mic compressor and tx audio equalization make tailoring any 
mic to work with the K3.

Jim & Scott,

Well said and I concurred without reservation. I bought my K3 in August 
of 2011 s/n 5674 from K6XX
at the Rocky Mountain Division Convention in Taos, NM.
Elecraft is without equal in customer service and support.

Yes, if you study the text of this link, you will note that it comes 
with a Pin One Problem -- the cable shields are not connected to the 
chassis, but instead go to "audio ground" and "PTT ground". This is a 
classic Pin One Problem, and almost guaranteed to cause RFI. Early K3s 
were also built this way, but I believe that's been fixed.

The FT1000MPs I owned (and sold to buy K3s) also had a Pin One Problem 
at the mic connector that caused RF feedback on 75M and 15M.

The ONLY proper connection of a cable shield is the CHASSIS.

Geez -- some guys will read something negative into the most positive of

I have great success with a 30 buck Behringer MX8500 using the Heil Kenwood mic cable and homemade hand or footswitch. I?ve tried MC-60?s in the past but have had RF issues. No RF problems with the Behringer combo. You can get a desk stand for a few bucks at Radio Shack or buy a nice boom off eBay for around $ 60 as I recall.

That's the implication because we as a society have an amazing ability 
to spin something like this in the worst possible way.

I can think of a few dozen other reasons that aren't as dire.

It's one of the reasons that most amateur radio companies don't have a 
forum like this, and the owners and employees don't speak publicly.  If 
you don't say something, no one can take it and spin it out of control.

Hello Gordon,

I've been using the Heil HM-12 with my K3 (along with the Kenwood cable)
for a couple of years, and it works great. It does not come with a base,
although as I recall, it came with a foam windscreen as well as the
appropriate mic holder that would screw onto the stem from a Heil base.
Have never encountered any rf issues, and routinely receive unsolicited
"great audio" comments.

I don't know how many K3s will be there. At one time it represented something like 50% of the total. At 9 pounds, it's pretty easy to take a K3 anywhere.

K6XX is going because he's one of the world's top DXers. He just happens to work for Elecraft.

Unless you have a burning desire for a desk mic, the Elecraft hand-mic 
can be modified into a very decent mic. It already sounds very good - 
but, the switch is a complete piece of junk. Mine made terrible 
mechanical sounds each time it was pushed.

The fix was quite easy: I had an extra Heil square PTT button (they 
operate without any mechanical sound) and installed it into the hand-mic 
case. First open the mic case and remove all the mechanical switch 
parts. A Dremel Tool will help with the plastic molded stuff. Next, you 
get creative with a little Bondo (auto body filler) and reconstruct the 
case to support the new PTT switch. DO NOT GLUE THE NEW SWITCH IN 
PLACE!!! The new switch is designed to push and lock into place - make 
your modification to accommodate this (you may need to replace the 
switch at some time in the future). Pop the switch into place and solder 
the PTT lines. Reassemble the mic case.

I have been using mine for well over a year and it has worked perfect - 
no mechanical noises when the PTT is pressed. Before the mod I was 
getting bad reports from the PTT switch's mechanical noise. Now it is as 
quiet as VOX.

And, don't get discouraged with an MC60. I have one and NEVER had any 
problems with it - on the K3 or other rigs it has been on.

I use a 50 year?old Shure 444D, I did make an adapter from the K3 to the 1/4 phono plug on the Shure. Works FB not to mention it matches the K3 pretty well.

Subject: [Elecraft] KX3 Power on issue
Message-ID: <1404842441901-7591024.post@n2.nabble.com>

All,

I just joined the list and have a factory assembled KX3 for about the last 8
months.  KX3 has had little use as I worked on putting together the power
supply and antenna.  I have discovered a new issue and I am not sure what
caused it. 

I updated the firmware to the latest version last week of the release
firmware.

I believe I turned it on after the firmware change, but not sure now.

I updated the heatsink to the one from ProAudioEng.

I added internal batteries 2500mAH to make use of the internal battery
charger and RTC.

Symptoms on power up:

TX light stays solid red.  triangle f (delta f) is solid orange.  OFS and B
square (square around B) are solid green.  The KX3 would not power off, so I
removed one of the internal batteries which allowed the unit to power down.

Thought issue was releated to internal batteries not being powered from a
higher current source, so I put battery in and added external power.  Same
as before and had to remove battery to power off.

Went to just external power, issue remained but I was able to power off. 
Sometimes the KX3 power ups if I hold the buttons to turn it long enough.

Only change I did on the firmware beyond updating it was to have a startup
message with my call.

I would appreciate any thoughts on where to start trying to figure out the
issue.

Thanks,
Stan Frady, N1BBS

Few ideas
Unplug everything on left side of radio, but pwr.  Try again
If still a problem, Check /re-seat the flex cable between the two main
boards.  Might have been pinched or moved when you added batteries.

Yes, this is one of the great communications mics. When it was 
developed, many years ago, there were some serious hams at Shure.

As Don noted, virtually any dynamic mic, balanced or unbalanced, and any 
unbalanced electret mic will work just fine with the K3 or KX3. All it 
takes is the right connector with the right wiring, and the K3 and KX3 
connector pinout is shown in the manual.

I had an email from support at about 9:30 Central.  Asked me to tighten the
screws on the bottom panel that go to the LPA.    Then perform the TX gain
calibration.  The rig worked perfectly after I tightened the screws but did
the calibration to be safe and passed with flying colors.

Great service and support as always!

Elecraft support might be better than "great". Perhaps "unequaled" or "awesome". 

I've been part of a medium-audience product and given really good support to customers large and small (from IBM and HP to small universities at a 50% discount). We had something upwards of 10K customers over a 10+ year product lifetime, not that different from Elecraft. I think Elecraft gives better support than we did, and we still have customers that fondly remember the good old days when their search was Ultraseek.

I've only had one interaction with Elecraft support, and it was prompt, clear, and helpful. That is a LOT harder than it sounds. They care.

Hardly.  That's got to be one of the silliest extrapolations I've seen 
in a very long time.  The much more plausible implication, especially 
considering the history of the several thousand K3's that have seen 
pretty hard service around the globe, is that Elecraft wants to gain 
bonus points with the most visible of their customer base by having an 
engineer on standby to support their product.

Thanks for the calibration, though.

Hi,
I may have stumbled in the same issue on my recently acquired second hand K3 and I'd like see whether a similar component is present in my stock before cleaning up the desk and opening the transceiver.

On the schematic it's listed as "100" so I think we're talking of a somewhat generic rf-blocking non-critical 100uH value.

Can anybody please confirm?

Thank you
Stefano IZ0MJE

Subject: [Elecraft] K3 Ant 1 and Ant 2 Isolation?
Message-ID: <53BD4467.7010305@comcast.net>

During FD we were discussing portable antenna options for next year.   
We were considering a 33' fiberglass pole with a veritical and a G5RV on 
the same pole.  A 31' piece on wire running vertically down the pole and 
also a G5RV supported by that same pole.  Then just connect them to the 
K3 Ant 1 and 2 jacks and away we go, however should we expect to flood 
the Ant jack which is not in use with RF due to the antennas being so 
close?

Any thoughts?

Rich,

It all depends on how you have configured the AUX ANT input for the subRX.
If you have configured the Sub AUX ANT to use the non-transmit ANT1/2 
jacks, then you may have a problem with overload and COR activation on 
the non-transmit antenna.  In that case, the use of some external 
protection device may be prudent.

If you do not have the subRX, it should be no problem or if you have 
that subRX AUX ANT connected to the BNC jack, there should not be a 
problem as long as the BNC jack is left open or grounded.

The selection between ANT1 and ANT2 uses a relay, so except for the 
situation posed in paragraph 1, there should not be a problem.

Don W3FPR

Probably not a good idea.

The interaction between the vertical and the feed to the G5RV will be 
severe. You will have large quantities of RF forced onto the G5RV feeder.

I ran a quick EZNEC model of 2 verticals 2.4" apart. It indicates that 
at 100w you would induce 45w onto the feeder. Even QRP levels would 
not appear to be safe. I'd think you are pretty assured of blowing 
something up.

It would be an interesting experiment though, if you wanted to try it 
and report back on what burned up . . .

After trying several microphones I decided to take the plunge and bought
the Heil PR-40. What a difference does it make after proper equalization
with the built in K3 equalizer!.  Some people answer my CQ's just to ask
what my audio setup is. They like the "broadcast quality" of the audio. I
know many hams prefer the "standard" SSB audio sound and many even say that
the narrow filter bandwidth severely limits the usability of the PR-40. But
I still remember the rationale for the 20-20000 response of the high
fidelity equipment even though most people cannot hear beyond the usual 10
Khz frequencies. The explanation was that there is a special feeling when
you hear quality sound that is not experimented when listening to
"telephone quality" sound. I know what they meant. Remember the difference
between vinyl records and CDs? You might too. Just borrow one and do the
testing. Adjust your equalizer in a wide "V" from 50 hertz to 3200 Hz. You
will never go back to the telephone sound!

Message-ID: <CAMFZV824_qF+mK_FgYVR4ebP66HgOH48VqEcYb8mHX0FSDtSTA@mail.gmail.com>

I had a similar issue with my K3, it only happened on 15M.  It got even
worse with my KPA500 in operate mode.  I removed everything but a dummy
load and then started adding things back-RX antenna, KPA500, P3, etc...  In
my case, it turned out to be the mic cable pigtail. I put about a pound of
ferrite on it and the erratic power output has gone away.

As a side note, I even sent it to Elecraft to see if they could find the
source and as they correctly suggested, it turned out to be a local issue
with my shack.  The odd thing was that nothing about my shack had
changed-operating position, antenna location, etc.  It just started one day.

Good luck,

Caveat:  I admit to being 90 percent and better CW only and it has probably
been a year or more since I have had anything like a ragchew on SSB and even
longer in ( > 3 years?? ) since I have called CQ on SSB.

But, I find that the simple hand mic, the Elecraft HM2, works very nicely.  And,
I have been given good reports on audio.

I know it is not a desk mic but I am thankful to have gotten rid of the desk mic
I had (the Icom SM20, I think that is the model number) when I sold my Icom
equipment.  The desk mic took up too much room on the desk and it was awkward
to squirt it out of the way when I did not need it which was most of the time.  In
contrast, the hand mic is easy to move out of the way.

But, I am still puzzled by the interest in high-quality broadcast type audio.  To me,
as long as the audio is clear, no RF on the signal, not overdriven, and so on, I am
fine with it.  Even if the other guy is a little off frequency I am OK as long as I can
understand them and they can understand me.

OK, again, I admit, I am mostly CW so my comments may not pile up much, even
a hill of beans (black beans preferred) -- but I just had to ask this rhetorical question
as to why broadcast style audio is important in a SSB signal.

I have to agree with Phil on this.  I am by no means a crackerjack CW  
operator.  But, I find with my KX3, that most of the time I operate CW.
It just gives me more "bang for the buck" when running 5 watts with my  
KX3.  I have the MH3 mic, and have used it now and then.  In the past  
(QRO days) I did more voice operating.

But, for me, the goal here is to have intelligible audio, and there is  
little value in transmitting any frequencies lower than 200 Hz.   
You're better off generating RF that excludes those "low"  
frequencies.  Still, it is handy to have an on-board equalizer, so  
that you can make some tweaks to the audio response -for your  
individual voice-.

I used to work in broadcasting, both radio and television, so I  
understand that it's desirable for broadcast media to have a "full  
bandwidth" audio sound.  But, the fact is, that even with  
broadcasting, we would make individual adjustments -for each person-  
who was using a mic, so as to "make them sound good".. which was and  
still is a personal decision made by the audio operator.  The good  
audio operators, know how to adjust their audio mixing consoles to  
optimize the sound, and how it "sits" in the mix.  It's more an art,  
than a science.  And, one of the concerns when adjusting things was  
"how would this audio sound on a TV or radio with a small speaker".   
Those types of operators are referred to as having "golden ears",  
since they made the audio sound good on tiny speakers, as well as high  
quality audiophile speakers.

So, I also prefer broadcast audio for broadcasting, and communications  
audio for communicating.

Like you, I'm retired from pro audio, and I did a lot of live music 
mixing.  I also did a lot of sound reinforcement for difficult acoustic 
spaces.  One thing I had to learn is that human speech contains nothing 
useful below about 200 Hz, and nothing below 400 Hz contributes to 
speech intelligibility.  Those lower frequencies simply provide "body" 
to the voice, but also burn significant audio power (and TX power).  One 
technique that good live sound mixers use a lot is to roll off the low 
end of all the vocal mics (and most instrument mics) to minimize stray 
sound pickup of bass and drums. So while a live sound mix will have a 
lot of low end, it is NOT coming from vocals!

Likewise, there is little content in speech above 4 kHz, and 3 kHz is 
pretty much the standard limit for speech communications. That's partly 
because the higher frequencies also waste TX power, but mostly because 
they also cause QRM to adjacent QSOs on a crowded band.

> So, I also prefer broadcast audio for broadcasting, and communications

Yep.  I've still got a closet full of very nice broadcast and recording 
mics, but my ham rigs are optimized for 400 Hz - 3 kHz.

BTW -- it's also a good move with the KX3 to roll off the low end with 
RXEQ to improve headroom in the audio output stage.

Most interactions between feeders and antennas and other antennas and other
antennas' feeders can be managed with physical layout design and effective
attention to common mode current blocking.

To be aware of these interactions, one must cultivate vision of these
circumstances as a soup of *all* conductors.  Just presume every conductor
induces every other conductor, far and away a more accurate assumption than
just considering antenna wires and assuming feedlines are invisible.

Once comfortable with that inconvenient truth about ham sites, one sees
that some combinations of wire and ferrite just aren't worth the trouble.
Too much to figure out, too much to "clean up," particularly for field day
with its time constraints.

Issues between wires are modulated by the wire/rope/support opportunities
at a given site. In my case this last FD, optimally located trees in a far
corner of the property where an RV could be parked, allowed an interesting
specially designed sloped antenna I would never have tried in more crowded
circumstances for considerable cause (long story). This particular long
sloper turned out to be a killer on 40m CW (1119 Q's at 100w). It was
removed from interaction only by the 75 yards back to the nearest station
in our 3A entry.

With the all-conductors-in-play principle firmly in mind for a carefully
planned layout of antennas and conductors, no station ever heard the other.
With a trio of K3's in operation, even with frequent SSB and CW on the same
band, we heard no crud, no crosstalk, no intermod, no transmitted phase
noise, which is a much harder to satisfy requirement than not burning out
front ends. Some considerable portion of the credit for this result goes to
the K3's front-end immunity and clean transmitted signal. BOTH the K3
immunity/clean TX signal AND the interaction-scrubbed antenna layout design
were required to achieve this result.

The question as to whether paying attention to such niceties is a handicap
to a high score will be answered firmly enough by looking for N4C in the 3A
listing in November's FD score reporting -- PVRC NC at Grey Goose Farm. And
yes, the owner did name the farm after the vodka. You should see his man
cave :>)

Making interaction go away with a simple one-size-fits-all rule just does
not happen in less than very large spaces.  But understanding the
electronic physics of interactions and seeing all the conductors in the
solution, one can dance with the physics and the physical layout
possibilities to create some imaginative and excellent site-specific
solutions in the field.

EZNEC and an *all-conductor* model preliminary design is a very good start.

Beyond convenience, headsets have two valuable attributes:

1)  Headsets position the mic element in a consistent position relative 
to the mouth.  This provides consistent audio input - speech volume rem 
remains constant even when the operator turns his head, looks up or sits 
back in his chair, etc.   I believe much of what is blamed on 
atmospheric "selective fading" (or the like) is really the other guy 
moving about in his chair and getting inconsistent microphone input.

2)  Headsets are close-talking microphones.  Because you are loud, 
compared to ambient noise in the shack, they tend to get you, while 
"rejecting" the ambient noise - a matter of stronger signal relative to 
noise.  A desk mounted microphone mounted farther from you tends to hear 
you and the noise up more evenly.

My only pet peeve with headsets is the number of operators who place the 
mic element in front of the mouth, where one can breath into it, and 
where it tends to pick up "plosives" - i.e., popping of Ps and Bs and 
puffing into it.   The mic element should be placed off to the corner of 
the mouth, away from all that.  A local guy on the repeater system does 
this all the time... we like him, but he drives us all nuts when he's on 
the air.

Just MY take anyway.

Hi to Rich and the group

During field day I ran my KX3 with the tuner from the KXPA100 at 5 watts. I had my 44 ft doublet fed with 22 ft of window line on my 24 ft painters pole in the center with a 10 ft PVC support on each end of the doublet. I had a 33 ft MFJ fiberglass mast with 29 ft of wire fastened to it as a vertical about 2 ft away from the support for the doublet. The doublet through a W2DU balun was on antenna 1 and the vertical fed against the frame of my fiberglass camper was on antenna 2. Both antennas were pre tuned by the tuner on each band before field day started. I could chose either antenna instantly. Most of the field day the doublet was about the same as the vertical and I used it. I found the vertical to be the better antenna in the late evening and night on 40 meters so I used that. There was one weak point to my station and that was me as an operator but the KX3 and the 2 antennas worked great. I made 118 CW 5 watt battery search and pounce contacts and could have made many more if I was just a better operator. I hope my experience can be of some help. I have pictures on qrz.com not of field day but of the different parts of my station I put together for field day.

Then just connect them to the K3 Ant 1 and 2 jacks and away we go, however should we expect to flood the Ant jack which is not in use with RF due to the antennas being so close?

 Anyone from Elecraft, will the K3/P3/SVGA ever have the ability to decode on the P3/SVGA attached big screen while NOT sending the decoded output to the K3 VFO B area? I know it will decode to the large screen and at the same time send that decoded text to the K3, but it sure would be nice to NOT send the the decode text to the K3 VFO B area. I certainly have NO idea what's involved, but it seems it might be a firmware change.

 I have been debating an SVGA add-on, since I have my K3/P3 and KPA500 pretty much loaded for my needs, but don't see any real benefit to the SVGA card without the above stated ability.

 Seems a few others have also thought this a good idea some time back, but I thought to ask again. Is it on an Elecraft 'to do' list?

BTW, my K3/P3/KPA500 is the best ham gear I have ever owned and operated in 50+ years of being a ham! Nothing else comes close. And, I have had a LOT of gear!

The P3 SVGA doesn't do CW, RTTY, or PSK31 decoding.  The K3 does the decoding and presents it in the VFO B area.  A copy is available through the K3 serial port programmers command set, and P3 SVGA uses that TB command. The K3 Utility uses the same K3 decode mechanism for its Terminal page. The heavy lifting for TTY, PSK, and CW decoding is done in K3 firmware.

I would like to echo Jim's request.  I have the SVGA in my P3, and it's
really nice, but I don't like losing the VFO B readout when I'm decoding
RTTY.  It makes no sense to have a few characters being decoded on the K3
when hundreds of characters can be on the SVGA monitor.

I understand that the K3 is doing the decoding, but does that mean that it
must be presented in the VFO B area?

Thanks Dick! Not the answer I was hoping to hear, but it makes sense now 
that I think about it. So, the K3 utility terminal screen is the same as 
what as seen on a P3/SVGA. I've should have thought that out, but sometimes 
getting older doesn't always make it easy.

You answered my question, but probably no P3/SVGA card/LCD in my future. 
It's pretty, but with my limited RTTY/PSK usage, not necessary to me. The P3 
does what I need it to do, and 'fits' on my desk.

73 ... and Thanks!

I totally agree with N7US. It sure would be nice to just preserve VFO B, and 
let the decode flow to the other devices.

Also when thinking about getting a P3 and SVGA card what you see on the P3 is
not what you see on the SVGA monitor if you turn on the NB.  The weak
signals are covered up by the noise on the SVGA screen.
The NB works great but is not carried over to the SVGA screen.

That is because the P3 is fed from the output of the first mixer -
*before* the narrow filter, IF noise blanker gate and before the DSP
noise blanker.  Of course, one can upgrade to the most recent beta
firmware an enable the *separate* DSP noise blanking in the P3 SVGA.

I tried out the CW decode functionality on the KX3 for several evenings 
and I'm struggling to get very positive results. Basically, unless the 
received CW signal is peaking close to s9 and the noise is s1 or less 
then decoding seems unreliable.  If the signal drops towards the noise 
then everything just falls apart. I've tried various settings of 
threshold, pre amp On/Off, RX bandwidth etc., but I'm struggling to get 
successful results.  Can anyone tell me what to expect in terms of 
performance, and what might be the ideal settings for best reception?

The reason I've been trying this is because I've paired my KX3 with KX3 
Companion, a Samsung Tab 3 8.0, an OGT cable, plus the data cable that 
came with the KX3.  I've been able to remotely control many features of 
the radio, send CW and use up to 20 canned message macros, as well as 
direct input from the keyboard.  KX3 Companion also has a logging 
capability and polls required information from the rig (freq, time, 
mode).  While the KX3 Companion is not 100% perfect yet, with a little 
more development it could be a very powerful add-on to the radio.  If 
you're interested in this sort of thing I would definitely give it a 
try.  Please note the KX Companion required USB Hosting on the mobile 
device - the Samsung Tab 3 7.0 does not support this.  The Tab 3 8.0 and 
10.1 do.

Having the K3 NOT display the decoded text in the VFO B area is really a
point for Wayne.  I'll forward that request to him.  When the P3/SVGA is
showing decoded text, it's doing nothing more than periodically sending "TB"
commands to the K3. 

Regarding the noise blanker.  If you're talking about the NB feature in the
P3, the plan is to add that feature to the SVGA firmware as well.  Otherwise
the IF output from the K3 is coming from the 1st mixer as Joe pointed out.

Using the latest beta firmware for the P3 the NB "does not" apply to the SVGA
screen.  It only works on the built in P3 display.

Subject: [Elecraft] K3 P3 SVGA - ?future firmware updates for K3/P3/SVGA?
Message-ID: <53BEE6AF.9010303@gmail.com>

first let me say to Wayne, this is not a spur of the moment, 'should 
have waited over night to cool off' email. I have been biting my 
tongue/fingers over this for a very long time.

After reading the recent   [Elecraft] K3/P3/SVGA   thread,
I felt it is as good a time as any to ask a few questions of the folks 
at Elecraft.

first a rhetorical question or two to set the tone, hi hi

1st
Is there any guesstimate when/if Elecraft's firmware engineers
will stop tweaking *ONLY* the new Elecraft hardware products?

2nd
...and be allowed to refocus on firmware promises made over the previous 
many months/year(s) for the K3/P3/SVGA

what promises you may ask? ...
check out the 'many' requests Wayne says he has on his 'to do' list. I 
haven't kept track of all of them, (I'm sure the ones I want may differ 
from others wishes) but Wayne often says he has a list of 'good ideas' 
that will be (or at least considered for) implementation in the future, 
maybe he will share with us what is actually on that list?


My fear is that Elecraft may have reached critical mass, like many other 
excellent small companies, that were great when they started, only to 
grow and become so well known, that they were unable to keep up with the 
expansions of their products and their reputations started to suffer.

Why do I say such blasphemous things about the company whose products 
and services I am truly in awe of? Because this dangerous downhill trend 
I'm speaking of, first becomes evident as shown by the companies 
inability/failure to keep promises made in their earlier years when they 
were building their reputations.

will I switch companies, never!
am I a kool aid drinker, always and forever!

However, am I kinda tired of waiting for promises made, as I watch all 
the 'new stuff' getting all the attention, you betcha!

Yes I understand new stuff will have bugs and will need special 
attention and the new owners of those products also deserve all the 
attention we K3/P3/SVGA owners used to enjoy.

Do I bad mouth you products to others asking about buying Elecraft, no I 
still speak well of their performance. But I have noticed my enthusiasm 
when recommending your products has taken a notable shift. I use to have 
the highest of praise for *every aspect* of Elecraft, the Hardware, the 
Service and the Firmware. Lately I have dropped off mentioning how 
awesome your quick firmware updates are and have to catch myself to be 
sure not to go off on a rant about the problems we are having these days 
with shelved requests and delayed promises.

all I'm saying is maybe it's time to reinvest some of that 'new product 
monies' that is taking so much of your current time and energies, back 
into the company and hire some more software engineers if the burden of 
support for your mature products is suffering as badly as it is now.

That is if you want to turn around the declining trend we see now, and 
not be perceived as changing modes to 'riding on your former reputation' 
like many other past companies did, that cost them their reputations. 
The 'we'll get around to it' responce, is getting extremely old!

my apologize for adding to your burden Wayne and the rest of the crew, 
but perhaps you need to hear how some of us among your loyal followers 
are feeling out here, if that's what it takes to get you to change back 
to the company you use to be.

signed NOT A TROLL!

Message-ID: <CAD+2GyvW=V5Z9g4RKMjg_8QV_vv8EUAsCkOT_j5bN5W-8+BZUQ@mail.gmail.com>

Thank you for all the input.

Antennas are a fun thing to talk about and something every one seams to
enjoy and building their own, like I do.  I had many wires antennas in the
last 46 years.  I am still learning.  One thing I have not done is get a
computer program for my Apple Computer and an antenna analyzer with
software for it. So I do every thing trial and error.

So far I found that the KX3 and KXPA100 internal tuner seams to be as good
or better than the MFJ 989B that I had for many years. there were 2 tuners
that were as good or better than this back in the day. Tuners have not
changed much since then except for the introduction of auto tuners.  I have
a MFJ 998RT that I blew up on 160M with 500 watts MFJ replaced it for free.
 They shipped me a new one and I have not even opened the box.

With that said, I have been searching for that antenna that will tune 160-6
meters and found out on this forum it does not exist.  I never attempted to
do this type of search. I now know why Wayne had stated that in Digest 123
Issue 6 about 3rd harmonics on the same coax. Jim Borwn comments are words
of wisdom to stand by.

I try to stay away from baluns as much as possible. Hairpin matches seams
to be the best route, and I had proved that with tests on and spots on RBN.



I have to go to work now and will be gone for a couple of days and I know I
can add more to this. Took me a while to go through all the comments, and I
had forgotten some of them. so my apologies for not mentioning them.

Thank you for all your help.

Hi Martin,


are you using the latest version? Free or Full version? Which version of Android are you running? Are you using the external PA?

About sending... are you using the SEND or XMIT mode?

In any case... later today I'll release an updated version dedicated to Field Day with improvements on the logging side. More about it later.

Message-ID: <CFE44C7A.4B44%edauer@law.du.edu>

A week or two ago I posted this question:  Would it be possible to have
the P3's SVGA output displayed on the screen of a MacAir computer, and
have a logging program resident on the same computer, and be able to
toggle between the two with a simple computer keyboard stroke?  Neat trick
for contesting if there's no room for dual monitors, eh?

The simple answer (but see below) turns out to be no - with some dongling
older Macs could operate as "dumb" monitors but newer ones (like my
MacAir) cannot, a fact I had confirmed by a tech at the local Apple store.
 I was told that only the 27" monitor (too big for my space) might be able
to do that, and maybe it couldn't either.

I was referred by a member of this reflector (thank you) to a
computer-consultant friend of his, from whom I learned that there was no
direct way to do it but that it could be done if the P3's SVGA output
could be made into the electronic equivalent of an Internet web site.
Moreover, he said, that should be possible using something called
"Raspberry Pi."

Right.  For an EE or computer expert, maybe; but not for a Liberal Arts
sort of guy.  Even my Internet research about "Raspberry Pi" was
entertaining but incomprehensible.  But that aside, does anyone know of a
way to feed the P3 output into a server sort of thing and have it come out
as something that will fool the MacAir into thinking it's a web site,
hence toggleable vis-a-vis the resident logging program?

If it turns out to be patentable I'm willing to share the royalties . . .

I have worked at a technology company for many years and there is always
a tension between coming out with the new and nifty product and
improving the old product.  You have to balance keeping your current
customers satisfied with breaking into new markets and acquiring new
customers.  Yes, us K3 owners can always want more.  But, looking at the
initial K3 and what it has today, the ability to keep getting
replacement parts, and the personal support we get on such an "old"
product, I have to give Elecraft congratulations on how well they do. 
If I had bought a competitor's product when the K3 came out, more than
likely, I would have whatever was delivered.  With the K3, not only were
improvements made over the years, I could upgrade and/or install those
improvements as they came out.  Someday, the K4 will come out and I know
I will have some envy.  But I am still very thrilled with the value that
has been delivered today and I continue to expect some incremental
improvements in the future however slow they are delivered.

I don't know what a MacAir is, I've pretty much managed to avoid the 
iWorld.  I can tell you about the Raspberry Pi [and others] however.

Raspberry Pi [and Beagle Bone, and several others] are tiny little 
processor boards with weird names that run some flavor of LINUX, and 
thus will run LINUX-based applications, a great number of which speak 
Internet/Web.  You can do a great deal with them because of that.

I built a 40-station irrigation controller for my wife using the 
Hamstack components [hamstack.com] based on a Microchip PIC.  Aside from 
using their and Microchip C libraries, I had to write all the functional 
code in the PIC myself.

The Hamstack guys [who I know quite well] have now added Beagle Bone and 
maybe Raspberry Pi to their line, which allows you to capitalize on 
already created applications and modules.

Hope this helps.  I wouldn't be holding my breath for royalties, 
however. :-))

Well, I would call that maybe harsh, and for sure commercially unrealistic.

We do not pay for firmware changes, while Wayne's employees have to be paid
every week, the rent paid every month, etc. ad nauseum. So, even though
there was a lot of improvement needed from version zero of the K3, we are
far on the other side of having the K3 quite good enough to sell as is. A
K3 firmware change entirely for the K3 only has become pretty rare. Most
are integration work for the entire K-Line.

We have gotten as much as we have because we supplied the hard testing and
allowed a gradual implementation. Wayne has followed a change regimen that
provided an amazing collection of improvements. He certainly leveraged all
that into the KX3

Myself, I can't honestly think that Wayne owes me anything at all. If he
does throw out some stuff, that's really neat. But at this point anything
else he does for the K3 is far beyond the call of duty. No other ham
manufacturer is even in the same order of magnitude as Elecraft
responsiveness.

I can wish and make polite, respectful requests. But IMHO to insinuate that
Wayne has some remaining unfulfilled duty to the K3 that he *must* supply
is unrealistic at best.

When I was in college, I had a few friends who were involved in the 
local AM and FM broadcasting scene.
I didn't need anyone to tell me that I didn't have a good "radio voice," 
so I got involved in the engineering side of the house.
So, getting the optimal mic, and making the optimal equalization 
settings, would be of limited value in my case.

It's sort of like my photography efforts - expensive camera and lenses 
with a poor photographer behind the camera.
If I shoot a good photo, it's purely by accident.

Besides, I've loved CW since day one (note callsign).

The "Mac Air" is a laptop. properly known as a MacBook Air.  It's the
'netbook' variant of the laptops.

As Far as I know, there is no way to use the internal display of a MacBook
to display anything other than the OS or an application. That applies to
anything with a display in it that Apple makes.

Why not just look at the P3 display?  Don't you need that to have the P3 SVGA?  I don't have a P3.
What about using a Softrock Lite IF to a USB sound card on the Macbook Air?  The Softrock Lite is about $22 but you have to build it.  You could also get a LP-Pan2, but you already have the P3 so you may not want to do that. 
A quick google search turned up this:http://www.epiphan.com/products/frame-grabbers/vga2usb/
It is $299 list price, but there should be other less expensive vga-to-usb devices that can be used on a Mac.
Hope that gives you a place to start.  Although I may not be understanding what you are asking al.  I do have a Softrock light IF to a sound card on my Windows PC.  I have not tried it to my Macbook Pro, but that is a company machine.

for clarification, perhaps I should point out that the only "must 
supply(s)" that was even intimated in my comments...

were based on the fact that Wayne has *SAID* he/they planned to 
*attempt* to implement these further firmware enhancements for their 
already awesome hardware.

If, as you say, that has been determined to be "commercially unrealistic"

Then to that I would reply, if they can't, don't intend to, or have 
changed their minds about it's feasibility, great, no problem, so be it, 
just inform us, don't continue to string us along after command 
decisions to the contrary have been decided.

However I do *NOT* think that is what Wayne and Eric have decided, nor 
do I think that is what they are doing.

(imo) I have the idea, they have just bitten off more than they can 
chew, with the staff they now employ, so why not consider contracting 
out some of these promised or unfinished coding changes so they can 
catch up.

I thought about this problem for a few minutes a few months ago.  Decided it was not worth the
hassle.  Therefore, if I want a larger screen for the P3 then I would use an SVGA monitor that
could be bought for $50 to $150 depending on lots of variables.

But, if you want full rig control (logging at least) on a Mac then the there are a handful of products
that do that but they do not include panadapter features (as far as I know).

As someone has suggested, you could possible use a frame grabber which would take the SVGA
output of the P3/SVGA and then display the results with a suitable app on your mac but that seems
to be going way overboard and I am betting with less than excellent results.  Fast real-time response
on the P3 screen may be difficult with a frame grabber approach.

I think there could be a great "market" (although likely free software) for a good Mac interface to
a K3 or KX3 that is akin to something like the Flex Radio PC software.  This would require something
different then a P3, the LP-Pan type solution instead of a P3, but the KX3 could interface directly with
its I/Q output.

Although Raspberry Pi is indeed a Linux system, the cpu is not Intel so any of the software that is available for
Linux must be built from sources on the Raspberry Pi system (unless it is provided by rPI's distro).

Not every ham radio operator is equipped to build large complicated applications from sources.  Even though 
various Linux distros make this easy, it does not mean that everything is easy.  So, to get a package buildable
on Raspberry Pi Linux may require a bit more programming and Linux/Unix/GNU knowledge than typically held
by the everyday ham.  This includes fooling around with the configure script or at worse making source changes
to the software.

Plus, there are some available Linux packages that may require language compilers that are not available on
the Raspberry Pi distro.

<sigh> This is not a difficult problem to solve. First off, the MacBook Air is _not_ a netbook. Netbooks are defined by their low-power processors (typically Intel Atoms). The MacBook Air has a full multi-core Intel I5 processor, which means it can do real work.

The best way to approach this is to look for a USB video input device, such as those from El Gato, which can input video to the Mac. From there, just use the El Gato application to display the video, or save it to disk.
I don?t know if El Gato has a VGA-capable converter, but I do know they have devices that can input other video formats such as those common to current TVs and DVRs. I believe their URL is www.elgato.com or something similar. You may have to search for a suitable device that does VGA, and I suspect it won?t be inexpensive. Still, worth the effort.

I would expect the conversion task to take a notable amount of processor horsepower since much of the conversion occurs inside the Mac. This means that that extra horsepower you get because the MacBook Air is _not_ a netbook will be very useful.

You might also want to look at an alternate solution - an external monitor that the P3 and the MacBook Air can feed. While this solution means that you can only see one or the other video sources at a time, it might actually be less expensive.

Hi all,

Our firmware task lists are sorted by priority. Determination of Priority is democratic to some degree (Squeaky Wheel and other industry standard methodologies). But in practice it involves crystal-ball-gazing, head-counting, arm-wrestling-over-a-beer, and a healthy dose of what-we-have-time-for.

It is not practical for us to publish the lists. They change daily and contain a lot of firmware-speak. We'd rather spend time actually making changes than on sanitizing lists for public consumption. 

This is also the reason that we can't make announcements of the form "We will not ever get to feature X." (Imagine trying to do that with your personal Home Repair task list. Would your spouse let you unilaterally decide to remove some of them?) We'd rather be optimistic about it, since you never know when one of our overworked engineers is going to get some unexpected free time.

The most useful guidance I can give you is this. If only one or two users are affected by a particular change, it is less likely to be implemented in the near future. If nearly all users are affected, it darn well better be fixed instantly. Everything else is in a sort of gray zone (see "Determination of Priority," above).

I take responsibility for any muttered oaths against Elecraft pertaining to implementation delays. If it's any comfort: I read all the mail and lose sleep over things we can't get to. All I can say is that we try to make the best decisions we can, given engineering time available.

73,
Wayne

I greatly appreciate the work Wayne and others do to enhance existing 
products while developing new products.

As for the squeaky wheel method of prioritization, I often refrain from 
sending "me too" e-mails when I see a feature or product request that 
interests me (such as the one from this thread).  What's the best way to 
communicate that without flooding e-mails to the list?

Not sure what make you have, but I have a cheap little Radio Shack model 
that I take from virtually sea level (600ft) to Breckenridge, CO 
(9600ft) every winter and use quite a bit while I'm there. I've never 
had any trouble with it, other than running out of butane. I bought a 
new tip for mine not long ago and it seems to have more trouble 
lightning than the original one. Other than that, though, it's been a 
workhorse for me at all elevations.

Subject: [Elecraft] (K3) loose front panel microphone jack
Message-ID: <53BF63E3.8060503@wi.rr.com>

Hello all,

I noticed right before FD that my K3 front microphone jack is loose.  
I'm aware of the "washer" problem but think that was in earlier K3s.  My 
K3 is ~ S/N 5400.

So, two questions:

1)  How difficult is it to get to the mounting nut to tighten?  Is this 
a 1/2 hour job or are we talking about setting aside a couple of hours?  
Any helpful hints?

2)  Any hints on how to prevent this from happening in the future? 
Lock-tite??  Is there a recommended torque spec the factory uses?

I rarely operate phone and when I do I usually use the rear jacks. But 
I'd still like to get this fixed.

Hi all,

Our firmware task lists are sorted by priority. Determination of Priority is
democratic to some degree (Squeaky Wheel and other industry standard
methodologies). But in practice it involves crystal-ball-gazing,
head-counting, arm-wrestling-over-a-beer, and a healthy dose of
what-we-have-time-for.

It is not practical for us to publish the lists. They change daily and
contain a lot of firmware-speak. We'd rather spend time actually making
changes than on sanitizing lists for public consumption.

This is also the reason that we can't make announcements of the form "We
will not ever get to feature X." (Imagine trying to do that with your
personal Home Repair task list. Would your spouse let you unilaterally
decide to remove some of them?) We'd rather be optimistic about it, since
you never know when one of our overworked engineers is going to get some
unexpected free time.

The most useful guidance I can give you is this. If only one or two users
are affected by a particular change, it is less likely to be implemented in
the near future. If nearly all users are affected, it darn well better be
fixed instantly. Everything else is in a sort of gray zone (see
"Determination of Priority," above).

I take responsibility for any muttered oaths against Elecraft pertaining to
implementation delays. If it's any comfort: I read all the mail and lose
sleep over things we can't get to. All I can say is that we try to make the
best decisions we can, given engineering time available.

This was exactly my experience on FD at a slightly higher altitude. I 
had a Bernz-o-matic unit that worked fine at home before and after, so I 
attributed it to the altitude.

Gary,

The shell of the microphone jack will normally rotate slightly, this is 
not a problem.
If you notice carefully, you will find that the pins are not loose, it 
is only the shell that moves.  It is due to the way the jack is made.  
Since Elecraft solders the mic jack pins to the board, but does not 
mechanically fasten the shell to the front panel metalwork, this 
condition becomes apparent.

Should you want to "fix" it, you can remove the left side panel, scrape 
away a bit of the solder masking right at the base of the mic jack shell 
and solder the shell to the exposed copper ground plane. It takes quite 
a bit of heat because both the mic jack shell and the ground plane will 
suck heat from the iron, so use a large tip on the soldering iron for 
best results.

The mic jack shell is already grounded with a wire wrapped around it, so 
the soldering I mentioned above is only to keep the shell of the mic 
jack from rotating - in other words, it is entirely unnecessary.

The "loose washer" problem that you refer to is on the headphone jack.

Don W3FPR

On most of those irons there is a control to adjust how much air gets into the mixture.  On all that I have used you can change this to compinsate for altitude.

Basically, unless the received CW signal is peaking close to s9 and the noise is s1 or less then decoding seems unreliable.  If the signal drops towards the noise then everything just falls apart. I've tried various settings of threshold, pre amp On/Off, RX bandwidth etc., but I'm struggling to get successful results.  Can anyone tell me what to expect in terms of performance, and what might be the ideal settings for best reception?

I've been able to remotely control many features of the radio, send CW and use up to 20 canned message macros, as well as direct input from the keyboard.  KX3 Companion also has a logging capability and polls required information from the rig (freq, time, mode).  While the KX3 Companion is not 100% perfect yet, with a little more development it could be a very powerful add-on to the radio.  If you're interested in this sort of thing I would definitely give it a try.  Please note the KX Companion required USB Hosting on the mobile device - the Samsung Tab 3 7.0 does not support this.  The Tab 3 8.0 and 10.1 do.

That has nothing to do with flame from the stove.  Water boils at a lower
temp at altitude, so you have to cook things longer in boiling water.  At
7400 ft ASL, the boiling point of water is 198.5 F.

Thanks to all who offered suggestions on the P3/SVGA-to-Mac question; I
have replied off-list to each and will follow up their leads.  This note
is just to say how great I think this Reflector is . . . and how Eric and
Wayne's following it (per discussion in the same e-mailing in which the P3
SVGA issue appeared) reflects so well on the company that is Elecraft.
Thanks, all.

but not so it's annoying.

I tried RTTY and PSK31 modes on the bench this morning transmitting into

Predistorsion properties are impressive. The following presentation

http://users.burlingtontelecom.net/~n1jez at burlingtontelecom.net/images/Eastern_VHF_UHF_Conf_2014.pdf

gives some information what is possible. In LDMOS amp with bias almost
reduced to 0, IMD3/5 change from -22/-28db to -55/-63db. Also a crappy 13.8V
CB amp with IMD3/5 of -18/-28 becomes -47/-53 after predistortion.

Class AB amps have an efficiency of around 50%. B class amps (also in
drivers) perhaps can raise it to 70%. 40% less input current and 55% less
dissipation, all at excellent IMD. All for nothing, oops, for lots of
programming if DSP is powerful enough.

Perhaps in 10 years nearly all new rigs will have predistortion implemented. 

Probably K3/KX3 do not have powerful enough DSP to do it. For example, the
biggest limit in KX3 on SSB is speech processor that is currently just a
treble boost.  6db lost. The fact that it is not done means that it cannot
be done easily.

I skimmed the presentation. There are no surprises. Several thoughts.

First, this is pretty complex -- that feedback (sense) loop from the 
amplifier output is critical. Why not simply buy a cleaner rig and amp, 
and run them under conditions that make it cleaner?  Study the 
presentation that K6XX and I did for NCCC last fall.  The measures that 
Bob talks about are very easy to implement.

http://audiosystemsgroup.com/K6XXAmpTalk.pdf

A decent tube amp, carefully tuned, is about as clean as the results of 
predistortion, and is a lot simpler.

Also, it seems to ignore phase noise, which is produced by the rig. It 
also ignores sidebands produced by distortion that results from 
overdriving audio stages.

FWIW, I see no reason for Elecraft to support it other than possibly for 
their own power amps. I suspect Wayne has looked at it.

While I have a 5 Amp-hr Lithium Ion battery and 
use it, and also high-capacity Eneloops inside my 
KX3 (with the battery charger option) my preferred 
approach is to use ten external Eneloops in a 
battery holder made to hold ten AA cells, this 
sort of thing:

http://www.amazon.com/gp/product/B00AZTUI7Q/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1

That way I have no power limitations, it's easy to 
recharge the batteries (I have two Maha chargers, 
one 4 cell and one 8 cell, so I always have the 
ten needed spares available). Works good with a 
number of rigs (K1, KX1, etc.)

While the capacity is only 2 A-h or so (vs. 5 or 
higher with some of the newer, more exotic 
batteries out there) this works for me -- and the 
cells can be used for other things like a camera 
flash gun. And easy to change out the cells to 
fresh ones.

Right! The flexibility is good, and I have quite a 
few Eneloops on hand.

Yes, $10 is a bit pricy, David. Those are not 
exactly what I bought; I just searched Amazon for 
a link with an image; bought mine in a local 
store.  The 8-cell version is more common, but ten 
is a better choice for our rigs!

* * *

MCU 2.12 / DSP 1.30, 7-11-2014

? FAST MESSAGE PLAY: A long-hold of MSG (~3 sec) puts the KX3 into FAST PLAY mode. In this mode, the BAND+, BAND-, and FREQ_ENT switches can be tapped/held to play/repeat messages 1, 2, and 3 immediately, without the need to first tap MSG. To turn off fast play, hold MSG for ~3 seconds again, or turn the KX3 off and back on. NOTES: (1) In voice modes (using the built-in DVR), only messages 1 and 2 are available, corresponding to BAND+ and BAND- in fast-play. (2) At present, message chaining is only available in CW modes (with both normal and fast-play).

? MORE ACCUTATE KXPA100 ?TUNE? POWER OUTPUT (PA ALC FEATURE): More accurate control of the KXPA100?s power output during TUNE from the KX3. This applies to settings from 11 to 70 W (60 W on 6 meters). Above this point, KXPA100 drive is still estimated based on the 75-W factory calibration. This prevents accidental overdrive in conditions sometimes found during full-power portable or mobile operation, such as high SWR, high current, etc. NOTES: (1) PA ALC is enabled by default. To disable PA ALC, locate MENU:PA MODE, then tap ?1? (PRE) until you see ?PA ALC-?. (2) PA ALC only applies during TUNE, not during normal transmit. Also, if you change bands or adjust PWR, and want to fine-tune the KXPA100?s power output again, you?ll need to do another TUNE. (3) PA ALC does not apply if TUN PWR is in effect, since the TUN PWR limit is 10 W, bypassing the amp.

? KXPA100 TRANSIENT FAULT DISPLAY: Common KXPA100 faults requiring operator notification, such as high SWR, are always reported on the KX3?s display. Transient faults such as serial port errors are normally not displayed, since they rarely impact operation. For diagnostic purposes, such faults can now be displayed as ?FAULT nnn? where nnn is a 3-digit number originating from the KXPA100. To enable this mode, go into the KX3?s PA MODE menu entry and tap ?6? (DLY) until you see ?XFAULT+?.

? FULL SUPPORT FOR PX3 PANADAPTER.

? 40-METER TRANSMIT BUG FIX: The 40-m band-pass filter was being bypassed in transmit mode, due to a change in rev. 1.94 that allowed MARS operation from 8.5-9 MHz. This resulted in an increase in the amplitude of some narrowband 40-meter transmit images, most notably in FSK-D mode. (The low-pass filter setting was correct, though, which made this error hard to detect. Wideband spurious suppression specs were met.)

Right! The flexibility is good, and I have quite a few Eneloops on hand.

Yes, $10 is a bit pricy, David. Those are not exactly what I bought; I just
searched Amazon for a link with an image; bought mine in a local store.  The
8-cell version is more common, but ten is a better choice for our rigs!

I looked there. it appears to hold 8 cells, not 
ten. Plus ships from Hong Kong, so a bit of a wait 
:-)

The 10-cell holders seem a bit hard to find. In 
fact, I'd looked and not found one -- so I was 
quite surprised to see one in my local store and 
grabbed it.  My old standby is a 10 AA holder 
which came with an old Icom 02-AT!

You can find the 10-cell on ebay.  It does come from China and takes a 
few weeks.  But they're cheap.

Message-ID: <53C1253D.17616.11A54F8@furlan.gmx.net>

hi all, 

we made 2 tone measurements of my KX3 and compared it with my FT-817. 
There was one unexpected result with the KX3, and I would like to ask the group if this is 
already known or looks like a problem with my KX3. 

The IM3 peak is lower than the IM5 peak and it is asymmetric.

The first picture shows the KX3 alone with no PA:
http//oe9fwv.dyndns.org/oe9fwv/KX3/kx3_alone.gif

The second picture shows the KX3 connected to the Hardrock50 PA: 
http://oe9fwv.dyndns.org/oe9fwv/KX3/kx3_HR50.gif

any comments on this phenomenon would be appreciated.

You may be referring to the AGC PLS (AGC pulse) setting, which prevents 
a short pulse from activating AGC. It is on by default.

It is intended to prevent the situation, common on some receivers, that 
a single strong pulse deafens the receiver for a long period. I don't 
think this would be helpful with lightning static, though, which is 
repetitive longish pulses.

See the AGC PULS entry under the CONFIG Menu - Tech Mode section of your 
K3 Owner's Manual.  I think your friend meant that he newly discovered 
the feature, it has been in the radio for a very long time.

The problem I have found with AA cell holders of the 10 cell variety is
that there was unacceptable voltage drop under load. I tried this with the
KX1 and was not satisfied. I think it will take a pretty high quality cell
holder to get around that problem, which resides around the contacts and
interconnects.

Good Luck!

This is also very useful as part of the combination of settings that will
nullify key clicks to a surprising degree.  Sharpest possible skirts will
convert the typical form of a key click to a very sharp pulse. The normal
AGC PLS setting will "freeze" AGC for a very short period, but sufficient
to prevent the pulse from pushing down the instaneous RF gain.  With IF NB
off, DSP NB t1-7. t2-7, and t3-7 will take care of the key click audio per
se, making it possible to operate with some pretty bad clicks nearby. The
DSP NB does not have the artifacts that IF NB has to have in crowded
contest conditions.

73, Guy.

The "Think Tank Strobe Stuff" is a perfect case for the KX3.  However when
you put it in a backpack with other items, there is a risk your KX3 will
accidentally be switched on by external pressure on the respective switches.
I'm trying to prevent this by carefully packing my backpack.

Recently, when taking the KX3 out of its case on a summit two hours after
leaving home, everything seemed normal. The KX3 was off. When I switched it
on I was suprised about the low battery voltage reading because the 8
internal AA eneloop NiMH cells were fully charged in an external charger
just a few days earlier and took about 2.2Ah each. The big surprise however
came when I wanted to tune my antenna: The display went dead and the KX3
switched itself off. Back at home I confirmed that the NiMH cells were
completely discharged and that the KX3 is drawing around 60uA when switched
off, which is OK.

I prefer not to imagine in detail what might have happened inside my
backpack during my two-hour hike, but definitely the 2.2Ah were converted
into heat! Fortunately my KX3 seems to have suffered no damage.

Has anyone out there found an easy solution to protect the KX3 from being
switched on when carried around in a soft case?

Using 8 internal eneloop cells, I measured battery voltage versus current (as
shown on the KX3 display) during RX and different TX pwr levels, created an
Excel scatter chart and fitted a linear trend line. The result: 1.15 Ohms,
R^2 = 0.95.

A single eneloop cell has around 0.035 Ohms of internal resistance (measured
with a 4-connector battery DC resistance meter forcing current pulses thru
the cell under test).

My conclusion: 25% of the 1.15 Ohms are due to the 8 cells, 75% originate in
the battery holder and additional wiring.

Hello, List.

The pass band tuning knob on my KX3 has stopped responding to rotation for
no apparent reason, and performing a hard reset hasn't fixed the problem.
There isn't any evidence of physical damage, and the unit hasn't suffered
any trauma of which I am aware.  Does anyone have a suggestion as to what

defect?  Thank you in advance for any assistance that you are able to give.

When I was at Dayton last spring, I bought a plastic cover that fitted
snuggely on the KXE (snapped into place). Along with the cover came two
sides both right and left side. The label on the plastic cover was "Side
KX". These people had a booth opposite the Elecraft booth and they also
assisted Elecraft is talking about KX3. I also bought the heatsink add on
that really keeps the transmit transistors cool even at 12 watts SSB with a
continuous tone. The heat sink makes the KX3 like a very small Alpha
thinking "brick on a key" situation

Hi Werner,

> we made 2 tone measurements of my KX3... one unexpected result with the KX3...The IM3 peak is lower than the IM5 peak and it is asymmetric.


This is not unusual with MOSFET power amplifiers. We've seen such effects with 10- to 100-watt amplifiers made by various manufacturers. It's likely due to multiple IMD sources, including the PA stages themselves, class-AB bias, supply voltage dynamics, exciter drive level, low-pass filter matching, and impedance match between the exciter and amp. 

Depending on phase and amplitude of the contributors, IMD products from two stages may add together or cancel each other. The amplitude of resulting products is more important than any resulting asymmetry.

As outside observer, it seems the K3 is more of a process than a 
product.  I doubt it will ever be a finished product, with a static list 
of features and capabilities.

Instead, one buys into an ongoing, organic, developing process.  It has 
never been "finished" and likely never will.   You either accept the 
process or maybe you don't because they spend more time developing 
features you are not interested in, whilst the one's you desire remains 
on the wish list.

 From initial release to the present, the K3 has undergone continual 
development, subject to updates, upgrades, and re-design.  My friend 
ordered his before there were any actually built and available for sale. 
  The rig today is very different from what he expected at the time he 
placed his order.

As an ongoing process, it is subject to a myriad of vagaries and 
uncertainties, and (inevitably) disappointments that your feature did 
not get updated or improved or even off the drawing board.

So, you either like it or you don't.  You should buy it for what it can 
do on the date of purchase, not for what it might be able to do on some 
uncertain, unspecified later date.  Whatever it becomes should be seen 
as "gravy" or as a bonus.

As an outside observer, I believe the Elecraft management have 
intentionally bitten off more than they can chew so as to do as much as 
is possible, considering all ideas and suggestions, and implementing 
those within reach.  They could have opted to close the book and rake in 
the profits on a static set of specifications.

A unique characteristic of this process is that it is quite transparent, 
open, and shared with the consumer.  The company could have played its 
cards much closer to the vest, and there would be no disappointment 
because no one would have any clue what might come next, if anything, 
until it does.

Instead, they elected to take the far more dangerous, open course, and 
cut the customer in on the process.  THAT is unique, but does open the 
door to some disappointment as one's pet improvement remains delayed 
whilst others' desires are fulfilled.

I consider any future enhancement, upgrade, or improvement as falling 
into two categories:

1) mandatory updates to maintain or effectuate stated specifications 
(i.e., warranty updates)  and

2) optional updates implementing wish list items for additional or 
different features or capabilities.

The first type are required to comply with warranty obligations, the 
second type is optional and bonus to the buyer.  As I believe the 
Elecraft management is sincere, it will do its best to implement all the 
category 2 option features it can, within the constraints of time, 
resources, and profitability.

As such, while your pet update may languish on the drawing board, you 
did not buy the rig with that in mind, as it was not a stated feature 
when you purchased it, and you bought into a process which is subject to 
uncertainty.  But you have bought into a process where management does 
mean what it says and is doing its best.  I cannot see how one could ask 
for more.

No one else is as keen on selling a process, ... just the rig as it is 
on date of sale.

Just My take, anyway.

This would be a good slogan for Elecraft to use as a selling point.

In all fairness, though, this applies to pretty much any SDR-based radio.

Interesting observations.  As one example of "wish list" items that is 
particularly close for me is my requests for the keying algorithms be 
expanded to include Ultimatic keying.   I have been asking for that 
since the early days of the K2, but so far has not been forthcoming.  I 
guess there are not enough other 'squeaky wheels' out there to make it 
to the list of priority changes.
I really don't mind because I have resigned myself to the use of single 
lever paddles.  It would be nice to be able to do dot/dash insertions 
that are possible with Ultimatic keying, but I simply cannot do Iambic 
keying with dual lever paddles.

Maybe someday Wayne will have time to add it, but I am not holding my 
breath, and I don't think my K2, K3 and KX3 are poorer transceivers 
because my request has not been implemented - there are other more 
important things "on the list".

I am also a single lever paddle user.  There must be others who also prefer a
single lever paddle over dual lever paddles.

It would be nice if a single lever paddle version of the KXPD3 was
available.  I don't own a KX3, at least yet :), but this might be enough to
push me off the fence.

Sorry for the threadjack.

And I am in the same boat...the 'not enough squeaky wheels' boat! 

Even though promised by Wayne, fixing or improvement of high speed full QSK
without losing other needed functions, in my opinion, just never will
happen. It's called 'close but no cigar'!!

Interesting observations.  As one example of "wish list" items that is
particularly close for me is my requests for the keying algorithms be 
expanded to include Ultimatic keying.   I have been asking for that 
since the early days of the K2, but so far has not been forthcoming.  I
guess there are not enough other 'squeaky wheels' out there to make it to
the list of priority changes.
I really don't mind because I have resigned myself to the use of single
lever paddles.  It would be nice to be able to do dot/dash insertions that
are possible with Ultimatic keying, but I simply cannot do Iambic keying
with dual lever paddles.

Maybe someday Wayne will have time to add it, but I am not holding my
breath, and I don't think my K2, K3 and KX3 are poorer transceivers because
my request has not been implemented - there are other more important things
"on the list".

There are two ways to look at this:

1) Elecraft, as a company that exists solely to make a profit, is 
something of a failure -- unlike their competitors, they fail to 
monetize new features and improvements to existing rigs.

2) Elecraft exists first and foremost to do really great stuff. 
Engineering runs the shop, and as long as there is enough profit to 
cover the costs and keep everybody reasonably happy (including Wayne and 
Eric), then they're perhaps the most successful Amateur Radio 
Transceiver company since, well, forever.

I think it's #2, and I think it's brilliant.

Wayne said something about "Beer" being part of the decision process on 
new firmware features.  Am I the only one thinking about a Kickstarter 
campaign for the Elecraft Beer fund?

Those are exactly the kind that have the most loss. Those springs for 
each cell are apparently made from resistance wire.

There are some low loss ones available. More $$$. Mouser used to have 
them. IIRC, they have a different type of spring.

Art sees the same thing I do.  Take those 10 springs, uncoil them and fasten end to end.  That surprisingly long, hight loss length of wire is what all the current has to pass through.  Far from ideal for keeping the voltage and efficiency up.

I have seen better designs incorporated into equipment but never in the secondary market.

Message-ID: <emef4ff65c-37ef-43df-a6ab-30d67ed2c179@hamradio-pc>

Bug users on the list - I've confirmed a design that works on the old 
Japanese Skillman & the newer Hi Mound "coffin" style bugs with the flat 
pendulum & plastic top cover.

I now make them to fit just about any bug out there as long as I can get 
the diameter of the round pendulum, thickness of the flat pendulum and 
at least a picture of the vibrating dot contact so I can determine the 
shape of the pre-tensioner hook.

There has been a slight price change for ones made from brass.

Aluminum ones are still $20 post paid domestic and $35 post paid to 
Canada and other international countries that accept U.S. International 
First Class postage.  Customs charges (if any) are the responsibility of 
the international customer.

Anyone interested, please email me off list and please don't comment on 
the list to keep off topic clutter to a minimum out of respect for the 
Elecraft users here.

The 700 Hz 8-pole INRAD K3 filters are back in stock.  However, this batch
is much smaller than usual, so it will probably sell out fairly soon; my
guess is before the end of August.

We made this batch so small because we are already planning ahead for the
arrival of a subsequent batch around November 15th; just in time for the
(winter solstice) holiday shopping season.

Hello Wayne,

I have tested this great feature on the weekend and it works really nice!

Just a hint: When the CW decoder is enabled and fast play is switched 
on, the hint text on the VFO B display becomes mixed up with the currect 
CW decoder text. It would be nice if decoder text is suppressed until 
the hint text display is over.

I'm in a hotel in Westborough, MA. 

I brought an EARC Hawaii end fed matchbox with its 30 feet of wire and fed the wire out my first floor hotel window sill edge and spread it out over the bushes in front of the hotel.  It was maybe 30" above ground and 30" away from the hotel building proper.  KX3 at 12 watts with a Powerwerx SS-30DV supply. I was trying to find WRTC stations, but 40 and 80 weren't active until after sunset.

Countries in my log over an hour (22z) or so on 20 meters: Germany, Slovenia, Poland, Belgium, Belarus, England, Czech Republic, Switzerland, Hungary, Slovak Republic, Spain, Russia, Bulgaria, and the US.

Then I shifted to 40 and 80 meters and looked for WRTC stations. Worked WR1TC in a nearby hotel, NU1AW, the IARU HQ station, W100AW, the ARRL HQ station, and 39 contacts with WRTC competitor stations in the local area.  I didn't stay up late.

Nice little radio!  I'm not ready to move to the East Coast quite yet, but it certainly is great visiting during an event like this. 

K1LZ was kind enough to open his station to visiting contesters who wanted to get in on the action. I operated a bit at NU1AW on 10 and 15 meters. Rates weren't spectacular,  but being the only IARU HQ mult drew callers. We could sit on one freq and they came to us.

Dennis, W1UE, asked if I'd operated much from YCCC territory; I admitted I had not.  He said there are 3 rules:

1. Run Europe,
2. Run Europe, and
3. Run Europe.

Now we wait until tomorrow evening for the results and the closing ceremony and then off toward Hartford.

Good deal, Dick. I have the KX3 and that antenna 
(which I have yet to deploy).

Only problem is that operating on the East Coast 
will spoil you for trying to work Europe with 
similar equipment from the West Coast. It's about 
the same as working Mass on 20 m from California!

In 1997 I was driving on the Trans-Canada Highway 
in BC and Alberta. I was amazed how easy it was to 
work European stations on 20 m with my mobile set 
up and a Hamstick vs. doing the same from California.

Enjoy your stay there, Dick!

I'll cite another example of a great company owned and managed by an 
engineer -- Dolby Labs. That fact made them extend development projects 
"for as long as it took," often for many years, far beyond the time most 
Harvard Business School types would have cancelled them. One of those 
projects was Dolby surround for cinema and home systems.

About ten years ago, I heard Ray Dolby give an invited lecture to the 
AES, and his talk was about the history of the management of that 
company. It is a manifesto for technical companies being managed by 
people who understand the technologies involved, and the market for 
them. Eric and Wayne epitomize that philosophy! They probably won't die 
as rich as Ray Dolby did, but I'm sure they'll die equally happy!

And fight like hell against any change in the scoring rules for DX

Use a better AA battery (3.7V 4.9AH Li-ion):
http://www.ebay.com/itm/181411959514

and battery holder:

Using 8 internal eneloop cells, I measured battery voltage versus current 
(as
shown on the KX3 display) during RX and different TX pwr levels, created an
Excel scatter chart and fitted a linear trend line. The result: 1.15 Ohms,
R^2 = 0.95.

A single eneloop cell has around 0.035 Ohms of internal resistance (measured
with a 4-connector battery DC resistance meter forcing current pulses thru
the cell under test).

My conclusion: 25% of the 1.15 Ohms are due to the 8 cells, 75% originate in
the battery holder and additional wiring.

The 3.7V rating is its voltage at about 50% state of charge. That type of
Li-ion cell has a fully charged voltage of 4.2V.  Four of them would be too
much for a KX3.

The 4.2V is the maximum open circuit voltage.  If you are that worried about 
it only use 3  Li-ion batteries.

Adding a couple of 5A diodes in series is a viable option as well, plus it 
adds the reverse voltage protection.

Message-ID: <1405301787274-7591154.post@n2.nabble.com>

A while back we tried Remoterig with a Kenwood radio and the CW generated was
poor on the other end.  This was presumably from dropped packets and or
latency issues (Comcast on one end and a terrestrial microwave connection on
the other end).  Some dits/dahs were lost and others were prolonged, due to
the lost stop signal.  My understanding of the remoterig protocol for CW is
it's not very robust, with no error correction or ACKing.

We got around the CW problem by using a VNC and the CW is generated at the
host end within the VNC window, using N1MM, directly keying the radio.

If we were to use a K3 and K3/remote for the radio, would there be potential
radio control issues due to the flaky internet connection, or is there
redundancy and/or error correction built into the Elecraft remote protocol?

Run pingtest.net and make sure you have a grade A rating. You don't need much bandwidth as 1mbs in each direction is lots if you are the only user. However, latency issues will cause problems. 

As I understand it, the K3/remote uses a remoterig interface. 

The problem may not be your ISP, but the routers you are using at both ends can contribute to your issues just as simply. 

Btw, I have been running a remote base with a ts480 for about 8 years. I do run CW by hosting n1mm at the far end and using a winkeyer.

I have discovered an issue with my K3, (ser 5820).

When using my Tigertronics Signalink USB device, the unit keys the rig fine,
but when the interface unkeys, transmission ceases, but red XMIT light stays
on and reception is muted.  Like an indeterminate state.

I did the following:

Updated firmware ? no difference.

Unplugged Signalink rig cable to r/o a short ? no difference.

Ran a different digital program on laptop ? no difference.

The rig is configured to accept audio input from the line in jack on the
rear when placed in DATA-A mode.  In SSB mode it accepts input from either
the front panel or the rear MIC jack depeng on whether I am using a headset
or the boom mic.  PTT is asserted through a foot switch via the front panel
MIC jack.  This keys and UNKEYS normally.

The Signalink assertes PTT through the PTT jack on the rear panel of the K3.
It has an internal relay acting like VOX.

When I use the signalink to key up in data mode, it works OK for a few
cycles, then reverts to the indeterminate state.  Rig will not receive until
I tap one of the keys mentioned below.

To rule out RF feedback issues, I keyed the signalink in SSB mode, so
line-in not selected,  Rig keys up but no power made, (signalink audio not
selected).  Problem persists.

Normal CW and SSB using foot switch PTT and either full or semi break in CW
has no issues, even when driving an amp and lots of RF.

CW through FLDIGI uses CAT keyup and release.  No issues there.  PSK uses
PTT asserted through rear panel.  Issue seems with rear panel PTT only.

Now here?s the really strange thing:  When in this indeterminate muted
state, if I tap band up or down, mode up or down, AFX, XIT, or RIT keys, the
unit goes back to normal receive.  That initial tap DOES NOT perform the
key?s design function.  This is like a computer keyboard when a screensaver
is running ? the first keypress is ?swallowed? to wake up the screen, then
subsequent keypresses work normally.  Any ideas here?

Thanks,

Dan Sherwood W6DAS

Wow, I'm glad I found this post.  I just completed building the control board
for my K2, and found the resistance on U6 pins 29 and 30 to be 96.4K.  I
didn't really think it was an issue, but it is always nice to have someone
else confirm it.  All other resistance checks were within specs. 

Thanks.

Dan,

That sounds more like a Signalink problem than a K3 problem.
Please monitor the voltage on the PTT input from the Signalink to the K3.

If the voltage when transmission is to stop is in the range of 3 volts, 
that is the problem - that voltage is in the indeterminate range for the 
typical logic levels.
OTOH, if the PTT voltage from the Signalink goes reliably to 5 volts, 
then you have a K3 problem.

Sorry Don, I'm new to the the Reflector, and didn't mean to create a problem.
I figured since I was replying to a particular thread, it would all make
sense.  I guess I was wrong. So hopefully, here is  some reference material. 
If I screw it up this time, just ignore everything, and I'll go away
entirely. 

Dave






Paul,

Yes, those are OK.  They are the DOT and DASH lines to the 
microprocessor and have nothing else but U6 on the Control Board to 
bring the resistance down.

In general, a 10% deviation from the values listed in the manual are 
close enough.

Don,

If I'm not mistaking, all the signalink does is use a relay to ground out
the PTT line voltage, much as a foot switch would do.  A logic high on the
PTT center pin would indicate a key up condition and should cause the rig to
return to receive state.

I could see where a flaky pull-up resistor could float the pin and cause
erratic behavior.

I yanked the PTT line, but the problem persisted.  I would think it would go
unconditionally to receive.  If it went high, it did not cause the rig to go
to receive.

The good news is I'm beginning to see the possible cause of the problem, and
it appears to be in the CAT rig control.  When I finally get CAT disable,
requiring a restart of FLDIGI, the problem seems to have mitigated.

Funny how you can run a configuration for 2 years and never have a problem,
until one day "poof"!  Perhaps the issue is software related after all.

73,
Dan

Yes, very nice. The only downside is that it makes the KX3 slightly 
larger (thicker) and heavier. But certainly less than any protective box 
that you could pack it in for travel.

Barry,

The RemoteRig system generates its own CW using an internal protocol, 
which solves latency issues. You use your key at the control end and the 
radio side RRC generates a clean CW without hiccups. It has error 
control and is (I believe) very robust. I know of someone doing 40 wpm 
full BK with no problem, but your mileage will vary, depending upon the 
internet connection.

As for the internet connection; there is a lot of discussion on the 
RemoteRig forum at their web site www.remoterig.com, so you can search 
there. In general, here are some tips:

The sum of bandwidth required:
- COM0 serial port bps
- COM1 and/or COM2 bps if used (i.e. for CAT or rotor control)
- which CODEC you are using, refer to appendix A in the Manual or 
http://www.remoterig.com/wp/?page_id=388
   I use CODEC 0 for almost all of my stations, which has proven to be 
more than adequate for SSB and CW.
- If you are running single or dual-channel audio (this doubles the 
codec rate requirement)
- There is some overhead in the 20-50 bps range

Remember also that this is doubled, up and down! Most DSL lines are 
asynchronous and have a lot less bandwidth going up than down, but the 
internet provider usually only advertises the down speed. You need 
therefore to take into account that the bandwidth used by RemoteRig  is 
the same in both directions.

Take into account the serial ports sent over the RRC, including CAT. It 
is not always necessary to run them at 38,400 bps! I recommend setting 
the K3 to 9600 bps to reduce your bandwidth that way.

I also need to point out that I believe that the latency is far more 
important than the bandwidth, especially once you are over about 250k 
bps. Often 3G lines have severe latency problems making them unusable, 
and satellite is not advisable at all.

Feel free to contact me directly if you have any further questions.

David,

Welcome to the world of Elecraft.

Do stay around - no harm done.  If you are using Nabble to respond, know 
that those of us on the official Elecraft reflector see only what you 
wrote and none of what you are referring to - unless you copy a bit of 
it in your post.  Nabble is not maintained by Elecraft - it is a 
secondary service.

The Elecraft list is not threaded, and it comes in as sequential 
emails.  My email client can show the posts as threaded if I want, but 
then I don't keep all emails on my computer, and I prefer not to use the 
threaded view.  With a bit of reminder text, most posts make sense for 
me - but with no reminders, they often have little meaning.

It does sound like you got through the resistance checks OK.  Enjoy the 
rest of the K2 build.

73,
Don W3FPR

Dan,

Yes, if you have both the CAT PTT turned on and are using the SL PTT 
line, that may cause "strange happenings".  Good to hear that you now 
have a handle on it.

Let me throw in a suggestion since you say it has been working before - 
look carefully at your serial port or USB to serial adapter (or the CAT 
output of the SL).  It may have developed a hardware fault on the DTR or 
RTS signals.

Message-ID: <53C3CCFC.80200@storm.ca>

You may have fallen afoul of what seems to be a "race condition" in the 
K3's firmware. When software (CAT) PTT and hardware PTT (from any of the 
hardware inputs, be it the AUX jack, the PTT IN jack or RTS or DTR on 
the RS232 port) are both configured from the same software, and both 
methods trigger at the same time, sometimes the K3 fails to switch back 
to receive. It doesn't necessarily happen every time; there may be minor 
timing differences in the software that affect whether it happens or not 
on any particular cycle. This problem has been around for years, 
probably since day 1. I have seen this from the beginning with my 
2008-vintage K3, and I am told that there are other transceiver models 
besides the K3 that have similar problems.

The solution is never to have two methods of PTT configured in parallel. 
This is a case where "belt and suspenders" is less reliable than either 
the belt or the suspenders alone. If you have Fldigi configured to use 
CAT for PTT, then do not connect or configure any of the K3's PTT 
inputs. If you want to use hardware PTT, e.g. from the SignaLink, then 
disable PTT via CAT in your software.

Incidentally, the hung up state is not an "indeterminate" state as you 
suggested in your first post. The K3 is in transmit; the reason nothing 
is being transmitted is simply that the software is not sending any 
audio to the radio, exactly as if you were in SSB with the rig in 
transmit but no sound coming from the microphone.

Interestingly enough I have something like that happen now and then as
well...

I am driving the K3 directly with a serial port from my computer, and in
DATA A mode, so far only when in DATA A.  I operate 90% in DATA A so
take that last one with a grain of salt...  Although it has never
happened in CW mode.

Once the problem has been triggered, if I tap the XMIT button and it
drops out of transmit.  Next time, I'll try a different button...  

I am using no interface...

One must remember, James, that Elecraft is a business, and a very
successful business it is too. Although the help and customer support is
beyond compare, the company is in business to make a profit.

It is understandable that concentration is given by providing support
and development for the latest product, earlier products taking a back
seat.

There are several features available on the KX3 which the K3 does not
have. One such feature is DTMF tone support for internet linking which
was introduced on the KX3 with MCU 1.73 last November but is not
available on the K3 despite the K3 being the stalwart desktop rig. My
guess is that the K3 is unlikely to ever have that feature.  I have come
to terms with that and have ordered the 2m transverter for the KX3. My
only hope is that the KX3-2M option will be available for my vacation in
September. I am encouraged by the statement that "New Orders to start
shipping by end of September" which suggests that back orders will be
shipped before then. Fingers crossed.

There are IMD graphs of KX3 at different power and voltage levels in FILES on
KX3 group at yahoo. IMD3 levels sharply increase with higher power and lower
voltage.

The IMD is are important only IMHO if KX3 is used at very high power level
on a crowded band. It is irrelevant for QRP operation.

Also, when the KX3 is used to drive a KXPA100, the rig is typically operating at well below maximum power, reducing IMD levels.

Jan, I had fun also, with my K3, operated about 7 hours total, 74 yrs young
is too many to stay up all nite, Made 314 cw qsos, and worked 54 of the 59
stations, a total of 98 times on 3 bands, 20, 40 & 80.  Missed 5 for a
clean sweep of all 59. Those ops were unbelievable, pulling one call out of
the pileups and very few times having to ask for a repeat. I guess that is
why they are the cream of the crop, of the contestors from around the
world. Just curious, I know the last one in 2010 in Russia, I heard that
40+ K3s were on the operator tables. Wonder if someone from Elecraft will
share with us how many were used this time.

73,

I have been using this without any trouble on WIN 8.1 Pro then,
I installed a new hard drive, and I can not re install the program.
When I go to install  I have a pop up that states. "requires .net framework

When I go to install this I get a message that reads "The .NET Framework

And then this becomes a circle. I am sure some knows that answer to this. I
would really appreciate some help with this.
My first thought was to uninstall the current version and install and older
version.
As I googled and found a lot of information and warnings
about uninstalling .net framework.
So I need some input on this before I attempt anything and possibly mess up
a fresh Windoze install.
Thank you for your help.
For now, headed out to the park this morning with the KX3 and Alexloop.
Everyone have a great day.

I would class the K3 as a "Middle Aged Product", a great deal of the 
originally planned capabilities and adjunct gizmos [KPA500, P3, KAT500, 
transverters] now exist, most have for some time, and the FW updates are 
tending more and more to small tweaks, occasional fixes, and responses 
to feedback, mainly on this list.  Even middle aged people can learn a 
new trick or two, but the K3 is a pretty stable product.

Contrast that with the K2 which is a definitely mature product serving a 
specific set of objectives.  Most of the K2 traffic on the list involves 
construction issues, appropriate accessories [e.g. headphones, mics], 
alignment questions, and lightning.  I'd be really really surprised if 
some new Elecraft gizmo came out that I could attach to my K2 to do 
something totally new that it doesn't do now.

Looks to me like the KX3 has graduated high school, resembles a 
20-something, and is still growing, very much as the K3 was 5 years ago 
or so.

Hi
I noticed that the dual PB function only works if the mode is cw and dual PB is set to APF in the tech mode menus.?
Is there a downside to always leaving this to APF as opposed to NOR? I mean you can turn APF on or off if set to APF, ?but not if set to NOR. Does the NOR enable another function??
Thanks, ?Tom

Hi all, I work on K3's all day and would like to advise/remind folks 
that lightning comes in through ANY path it pleases, not just the antenna.
Time and time again folks say they unhooked their antenna but the 
lightning took out the DSL modem, computer and K3 via the RS232 port!
Anything connected is a potential path...

Tom,

See page 35 of the K3 manual.

If APF is on, the SHIFT control set the audio frequency that you wish to 
hear.  NORM restores that audio frequency to your set sidetone pitch - 
no other function is enabled.

The APF filter is quite narrow.  While there is no downside to leaving 
it enabled, your tuning filters will be very narrow - good for digging 
signals 'out of the mud', but not good (IMHO) for tuning around to see 
what other signals may be present on the band.

I would suggest APF off for general tuning, and turn it on when you have 
to dig for a signal that otherwise might be buried in the noise or QRM.

I've found that the APF is very sensitive to the multitude of AGC 
settings available.  I haven't actually broken the code yet, but there 
are times an inaudible signal without APF rises to "copyable enough to 
get a Q" with APF.  Other times, not so much.

Just one more way to learn how to use my K3. :-)

Hello everyone,
     I had agreed to pick up the board production for the K2 MAB project.
Others took up the cause before I could get organized.  I now have one board
that I am going to assemble for one gentleman that decided the surface mount
parts were too small for him.  Does anyone else need help in getting the
parts on the board?  I can do the assembly work if you like.  I routinely
work with smaller surface mount parts in my day job.  I have the tools and
experience to get them put together properly.
    If you have decided the assembly is a bit more than you want to tackle,
let me do it for you.  I am about to order parts so I can add on extras
easily at this time.  Or if you already have the parts, I can put them on
the board for you.  Please let me know if I can help.

Message-ID: <1405397915625-7591188.post@n2.nabble.com>

Although I doubt if it is related, I just updated the K3 FW to 4.86 from
4.83. I used the KPA500 for first time after K3 FW update this evening and
when I switch KPA500 from STBY to OPER I get only the K3 25 or so watts out.
K3 shows asterisk to right of power on display so it is working okay (knows
to switch to lower power to drive amp). Set up is full Kline
K3/P3/KAT500/KPA500 all with most current FW. Never happened before.
Antenna(s) always hooked up to amp via KAT500 and pretty much resonant even
without the exteral tuner. Power loss is for all bands 10-80. Where do I
look? Help appreciated...mike  AI6II

I wanted to note the KPA500 is on a 220v AC line.

I did try backing off the K3 to FW 4.83 and also reloaded 1.38 in the KPA500
with no change in results. In running though the KPA500 menu, I noticed that
the INHIB IN was set to ENABLE, which according to the manual means ...

"ENABLE allows the amplifier operation to be inhibited (won?t amplify) when
a logic low is
applied to pin 11 of the AUX Connector (see pg 26). When amplification is
inhibited, an
underscore instead of the asterisk appears on the left end of the LCD
display." 

But this is not what I experienced (unless I don't understand what is being
said.) The asterisk was always there (not an underline) whether or not it
was set to ENABLE or DISABLE. In fact, going back and restoring from earlier
saved configurations I found the setting had been ENABLED since January of
this year. So apparently that doesn't work when using the K3 and Elecraft
AUX cable. Interesting....

I do now have it set to DISABLE, but as I said not no avail.  ..mike  AI^II

No problem overhere. Migh be your plug is not "activating" the "disable" contact in the socket. What happens if you plug in your headphones into the front socket? Does that disable the internal speaker correctly?

Hurray for LOW TECH! I 'wiggled the wires' and everything is working again. I
pushed on the chain of AUX cables connections to make sure they were all
seated in their sockets, and low and behold the amp is back to working
normally. I still don't understand how the INHIB IN setting works, but
apparently I don't need to. 

Glad I was able to work this one through.  ..mike  AI6II

This sounds like good advice.  However, every connector socket on my K3 
is populated, ditto the computer, ditto the KPA500, ditto the KAT500.

Pulling all wires when there is a potential storm threat is totally 
impractical.  Even if I did, I'm sure some of the connectors would 
simply not last.

I suspect others have similar situations.

The question is "how long are they?"? - Ethernet cables are typically 6-20 feet long.? A jumper between the rig and amplifier, much shorter.

Length determines how well it acts as an antenna.? The cables I worked with were perhaps 20-50 feet long, and made good antennas.? Some of the ethernet cables in my apartment are 50 feet long to feed from one extreme to the other. (I do video editing and need at least gigabit end to end...)

Telephone cables will be LONG.? Unplug anything connected to dsl or phone lines in general.

Luckily, the apartment I'm in has underground utilities.. However, that nice shot of a tower on the ground getting a direct strike was interesting.

It shows that having a few high trees around that are much higher than the antenna are NOT a reason to not disconnect. 


Lightning looks for an interesting way to ground.? Don't encourage it by leaving lots of paths in the shack available.?

Do TV Stations and Radio Stations and Cellphone towers disconnect all 
their equipment everytime there is a storm in the area?

Obviously the answer is NO they don't disconnect and they don't even turn 
their equipment off. Yet is survives direct lightening hits on their towers and 
equipment.

In other words there are ways that you also can protect your equipment 
without disconnecting it. You need a well designed ground system. This 
means a single ground system for everything that is in your home or a part 
of your antenna system. During a direct strike on the tower 90% of the hit 
should be bled off directly to ground through the ground system made up of 
many ground rods all connected together by proper copper connection. This 
leaves around 10% of the hit left for all the "Devices" that are connected to 
all the metal anythings that come and go from your home. Includes incoming 
power lines Telco lines Cable TV lines as well as all your rotor control lines 
relay lines and coax cables from the antennas. Anything that is metal that 
comes and goes from the house needs a protection device on it. 

I have three towers the tallest has antennas up to 175 feet above ground. 
The tallest trees here are around 70 feet high. So the towers get hit many 
times. They have been up since 1988. During the summer of 1989 I had a 
major hit on the tall tower that destroyed nearly everything in the house. TV 
sets microwaves all radios all computers many coax cables and other wires. 
But I learned the hard way to protect my system. I was placed on High Risk 
Homeowners insurance and the company that was assigned my insurance 
said I had 30 days to either get a proper ground system installed of get 
those towers all on the ground. We installed 100 ground rods all connected 
together by 1200 feet of 3/8" ID copper tubing. We installed a single point 
ground window where all the cables coming and going to the towers enter 
the house. Every wire has some sort of protection device on it. The main 
power line coming to the house has a protector device on it. The towers and 
antennas have since then withstood many strikes by lightening. Many 
surges from hits down the road that come in on the power lines. All with 
ZERO DAMAGE to anything in the house or on the towers. I did get lots of 
help from the techs at Polyphaser regarding how to build the system and 
how to install it. Total cost of this grounding system in 1989 was around 
$3,000 for all of it. Zero Labor as I and a couple other local hams installed all 
of it. Today we operate the station remotely during part of the winter so no 
way to unhook and rehook any of it. 

So you too can be safe and not worry about blowing up your equipment.

The alternative to disconnecting everything is to design your ham 
station to tolerate lightning events.
There was a very good 3 part series in QST for June, July and August of 
2002 that dealt with the design of a station for lightning protection.  
Those articles are available at 
http://www.arrl.org/lightning-protection.  I highly recommend it.

Some of the "ground rules" given in the article:
All towers and masts grounded with buried radial wires and ground rods 
to spread the impact of a strike over a large area of the earth.
Perimeter ground wires around any building with a driven ground rod at 
each place the wire changes direction. (lightning likes to travel in a 
straight line).
Bring all services into the ham shack through a common grounded copper 
panel fitted with suppression devices - that includes feedlines, power, 
CAT5 cables, phone cables, and everything else.
Keep any equipment or devices that are not powered/connected through the 
above panel out of reach of the operating position.

There is no guarantee that the above steps will eliminate failures due 
to lightning, but it will go a long way toward achieving that goal.  The 
real goal is to keep *everything* in the shack at the same potential 
during a lightning event.

I have attempted to use those guidelines in the construction of my shack 
and antenna field.  All my feedlines are automatically grounded when the 
station is turned off, and I do not attempt to operate when there is 
lightning nearby - and I get stay out of the shack during storms.
We had a lightning event here last year that took out the Ethernet 
router, several switches, 3 computers and 2 network attached printers.  
None of the ham gear was damaged.

Message-ID: <COL126-W343807801AA6D014D5129FCEF60@phx.gbl>

My K3 suffered a sudden loss of sensitivity this morning.  Yes, there was lightning last night.  The antenna input was grounded in an antenna switch but the receive antenna port was connected to a Beverage. 

It appears to be normal in every other way.  Transmitter ok.  Receiver functions work, like preamp, attenuator.  But the level is down >60 db.
It is the same on both the antenna jack and the receive antenna port on the KXV3.

I have some lab equipment (HP sig gen, spectrum analyzer) and made some quick checks but I need a sanity check:
With -40 dbm into the receive antenna port the S meter is S7.  
With -30 dbm input, The spectrum analyzer connected to the IF output shows -80 dbm.  I'm assuming this is WAY off, and should approximate the level of the input signal.

So I think I can safely assume the problem is not in the IF or downstream, but a likely culprit would maybe be a switching diode in the receive path?  Any ideas?

No.  I supported myself in college working at KSBY-TV in San Luis Obispo 
at the end 59 and early 60's  Our studio and TX were located on Cuesta 
Ridge overlooking the city, directly adjacent to the base of the 400' 
tower.  In the building, the multitude of cables [mainly 75 ohm coax] 
ran in trenches in the concrete floor, which were covered with 1/4" 
removable steel plates.

Lightning strikes [common in storms] only put us off the air once that I 
remember, but caused a totally deafening "clang" from all those trench 
covers. :-)  The one time we went down was just a popped breaker on the 
mains to the 10 KW visual PA, the aural PA stayed up.  We never lost any 
equipment to lightning.

Unplugging all the cables behind my K-Line, an area that gives new 
meaning to the term "wireless", would happen exactly once.  I'd never 
manage to get all of them reconnected.

I've had this happen a number of times after I've unplugged the serial

what you did, remove one of the batteries.

I volunteer for KBBF-FM, the local bilingual community broadcast station 
here in northern California.  The antenna is on top of Mount Saint 
Helena, north of Santa Rosa.  Compared to some areas of the country, 
lightning is not common here.

However, about three years ago the electrical pole that feeds the 
transmitter shack was hit by lightning.  The pole exploded and ended up 
in pieces on the ground:

http://kbbf-fm.org/images/DamagedPoleM.jpg

The electrical service entrance meter was blown off the wall.  We found 
it lying in the grass about 30 feet (10 meters) away from the building. 
  The main transmitter was fried and had to be removed for repair.  The 
950 MHz STL (Studio to Transmitter Link) antenna was also damaged beyond 
repair but, surprisingly, the STL receiver itself survived.

After repairing the electrical wiring inside the building we were able 
to get back on the air using the backup transmitter, the backup STL 
system and the emergency generator.

I think the moral is that it is pretty much impossible to absolutely 
protect against a direct lightning strike.  If I lived in an area where 
thunderstorms were common I would make my station as lightning-hardened 
as possible and ALSO disconnect everything when a storm is imminent.

Now that the unofficial results are in for WRTC 2014, and K1A (Craig, N6MJ 
and Chris, KL9A) seem to have the #1 spot to themselves, it would seem 
that congratulations are in order.

1. First to two fine contest operators who have been climbing in the
rankings!

2. Secondly to youth!  Both are in their low thirties . . . maybe they can
stay
    awake and alert better than the older guys :)

3. But thirdly, it seems that congratulations to Elecraft are in order!  We
do 
    know they used K3s in Moscow last time (WRTC 2010), and earned the top 
    US team score; #1 in QSOs and #3 overall.  And while I am not certain 
    about this, according to the video clip below they planned on taking two
    K3's with them this time (and a Mk 5 as a handicap :)

See the following video interview clip from DX Engineering:

http://youtu.be/OppRRdLfB6o

Intended equipment is mentioned around 5 minutes 30 seconds into the 
interview.

While I worked several of the WRTC contest stations on different bands,
I did not work K1A, so it is obvious they won on strategy :)  Don't waste
time with US causal operators :)

I agree with Brian, its not very easy to pull off all wires and cables if you have a complex setup with multiple antennas and radios with many cables attached. In the K1HTV Ham shack I use my K3 and a few other radios on multiple modes on the HF, VHF & UHF bands.  Rather than removing all cables each time a storm is in the area, it is much more important to focus on installing a excellent ground system. 

Here at the K1HTV QTH, I've installed a perimeter ground around the house with 8 ft ground rods every 16-20 feet. The 77 ft tall tower with HF, VHF an HF antennas on it. An array of 8 ft long ground rods fan out from the tower and are connected to it and to the perimeter ground wire where it passes the tower. All coax cables from the tower to the shack are at or below ground level and enter the shack via 'UHF', 'F' or 'N' Female-to-Female barrel connectors attached to a steel box. This box is also connected to the perimeter ground, using 4 gauge wire. Rotator and control cables from the tower enter the box and each wire is protected with gas gaps to ground. The shack ground and the AC power panel are both tied to the perimeter ground system so both are at the same potential. If this isn't done, a large difference of potential can be developed in a lightning strike. The shack has a single point ground which connects to the steel cable entry box. Where the coax cable leaves the multi-port HF antenna switch to be connected to the K3, there is a gap device to ground via a UHF Tee connector.

Using good grounding techniques, in my 56 years of Hamming I've never lost a piece of Ham equipment to lightning. That's not to say that there won't ever be a direct lightning hit that will cause damage. For now, I plan to continue to leave all equipment connected. Its just too impractical to disconnect everything.

Just make sure that your household insurance is paid for and that it covers lightning damage.

Rich - K1HTV

This sounds like good advice.  However, every connector socket on my K3 
is populated, ditto the computer, ditto the KPA500, ditto the KAT500.

Pulling all wires when there is a potential storm threat is totally 
impractical.  Even if I did, I'm sure some of the connectors would 
simply not last.

I suspect others have similar situations.

Hey Folks,

Elecraft was everywhere, and not just with many of the 59 WRTC teams...

We had a blast at the HQ Hotel while the teams were out in the field...  We
ended up having FIVE remote stations in the demo room at WRTC, along with
the WR1TC local station:

PR1T in Brazil, SK9HQ in Sweden, the RemoteHamRadio Blueberry Hill, NY QTH
as W2PV, Mt call running at K2LE/1 Vermont, and N3AD running single-op to
his home QTH.  Tree, N6TR, showed up to operate his Oregon remote, but we
ran out of table space -- so he operated from the IT office (for a total of
six K3 remotes).

All these remotes were all K3/0 minis running with Microbit RRC boxes on
the remote end.

Check out this video from the remote operating position at PR1T (It was
Eric, K3NA, at the WRTC HQ End...)

A great time was had by all!

Have checked the ribbon cable, even swapped one over from another KX3. If the KX3 is switched off for a couple of hours it will power up again. When I managed to power it up that seemed a good opportunity to reload the firmware which I did.

I found John, K9UWA's reply very interesting.  Seems a how-to manual 
is needed for folks exposed to lightning and wanting protection technology.

I am fortunate to live in a nearly lightning-free area.  We hear 
thunder maybe one time every 3-4 years and I have only experienced 
actual lightning activity during an hour long freak storm about 2 
years ago.  This experience is over 35-years living 
here.  High-winds, earthquakes, tsunami's, volcanoes - 
yes!  Lightning -no.  ...oh and winter!

The only time I hear lightning crash static is when propagation 
favors hearing from areas that have lightning.  Most of the time 
80/160/600m is static-crash silent.  600m is quiet all year long.

So it would be my guess that the important wire connections to 
disconnect are the ones that go outside the station:  all ac electric 
connections, all antennas, all telco/internet connections.  Interface 
wiring between pieces of equipment in one room should not be an issue 
as long as the "outside" world is disconnected. That should lessen 
the number of cables to disconnect.

My station would be a nightmare to disconnect with 17 coax lines and 
probably 2 dozen ac cords to disconnect.  Then there are the multiple 
rotator and control lines, some of which run directly to tower tops 
(four towers and a dish) with no break.  That's what you  get running 
on 14 separate bands from 600m to 23cm!

As a side issue - one of the stations down in tampa ended up off the air for a week.? A lightning strike melted their heliax and antenna system was destroyed.? The antenna was on the top of a bank building (about 70 stories up.)-- using the building frame as ground, and then in the ground under the bank building.

The transmitter, luckily, was not destroyed. (significant damage of course)? However depending on where you are, and the strength of the strike... all bets are off.? One station I helped put on the air (which had -2- layers of copper plates in the trench between the transmitter shack and the studio with the trench under ground had the entire rectifier stack in a Collins FM transmitter melted, assorted other stuff there... the lightning then hopped into the trench (on the ground) - and destroyed all the monitoring gear in the rack where it terminated.


.Of course, that is Florida, where lightning tends to be 2-5 times stronger than other spots in the country.

The alternative to disconnecting everything is to design your ham 
station to tolerate lightning events.
There was a very good 3 part series in QST for June, July and August of 
2002 that dealt with the design of a station for lightning protection.? 
Those articles are available at 
http://www.arrl.org/lightning-protection.  I highly recommend it.

Some of the "ground rules" given in the article:
All towers and masts grounded with buried radial wires and ground rods 
to spread the impact of a strike over a large area of the earth.
Perimeter ground wires around any building with a driven ground rod at 
each place the wire changes direction. (lightning likes to travel in a 
straight line).
Bring all services into the ham shack through a common grounded copper 
panel fitted with suppression devices - that includes feedlines, power, 
CAT5 cables, phone cables, and everything else.
Keep any equipment or devices that are not powered/connected through the 
above panel out of reach of the operating position.

There is no guarantee that the above steps will eliminate failures due 
to lightning, but it will go a long way toward achieving that goal.? The 
real goal is to keep *everything* in the shack at the same potential 
during a lightning event.

I have attempted to use those guidelines in the construction of my shack 
and antenna field.? All my feedlines are automatically grounded when the 
station is turned off, and I do not attempt to operate when there is 
lightning nearby - and I get stay out of the shack during storms.
We had a lightning event here last year that took out the Ethernet 
router, several switches, 3 computers and 2 network attached printers.? 
None of the ham gear was damaged.

Don W3FPR

As the  CE of a TV station in South Florida we had to contend with lightning 
during about 4 to 6 months a year (spring & fall thunderstorm seasons) in 
the highest lightning strike area of North America.
We did not ever shut down but did go to generator power during lightning 
within 25 miles; as seen on the radar display with lightning strikes 
superimposed.

We had a 1,049' main tower, 2-500' microwave receive towers and a 185' tower 
at the studio not to mention 2 bureaus with antennas on the 3rd floors.
The towers had massive ring ground systems. The rings varied from 20' 
diameter to 30' diameter. each ring had 10' & 20' alternating 100% copper 
rods cad welded to a 4-0 bare copper wire. The ring was attached to the 
tower leg's 20' ground rod with 2 or 3 radials per leg. The tower ground rod 
was set in the foundation to be next to the leg and connected to the leg 
with the least angle. (remember a right angle from the leg is a 1/4 turn 
inductor!). The guyed towers also had a ring ground system around the 
anchor.

All RF, video, audio & data signals going to the tower at the site were 
protected with commercial protectors except the studio tower which was 
replaced with fiber to carry those signals.

We probably took between 6 and 10 direct hits on a good year and many many 
more on a bad year.

The new studio & one of the bureaus had a ground system constructed to 
reduce lightning damage. The building had a perimeter ground system with a 
single point power & phone and the exit panel for RF, video, audio, data and 
dc control. The ground systems was 4-0 copper with ground rods about 10' 
apart.

We did find that our damage was reduced but not eliminated. We never went 
off the air; but we did have periods where we were using redundant (back-up) 
equipment for a while until the main equipment could be repaired.

Our largest reduction in damage occurred once we deployed dissipation 
arrays! These reduce the space charge in the immediate area in hopes the 
lightning choses another location (competitor's tower). My experience with 
towers, satellite antennas & ENG microwave antennas on 50' masts on trucks 
is that the dissipation array is #1 then a ground system followed with surge 
protectors. I would not chose one but all three.

We had a saying at work about lightning protection after repairing extensive 
damage after a bad hit - Lightning protection is akin to elephant 
repellant - just because you don't see an elephant does not indicate the 
repellent actually works. I spent over 30 years in South Florida and would 
never come close to guaranteeing that we had finally done everything to 
eliminate the risk!

Not sure at what point you should stop spending money on lightning 
protection for a hobby should go. For me at my new QTH it will probably be a 
few surge protectors, grounding each mast & tiny tower and a simple ground 
improvement to the house.

Ed,

I disagree.  While the bonding and grounding recommended as standard sound 
good, there are times when even that is inadequate.

I had a lightning discharge over my home in NJ - no direct hit, just huge 
induced currents in all cables, wires, etc., in the house.  The hair rose on 
my arm before the discharge.

I lost serial interfaces on a laser printer (no outside connection), Daisy 
wheel printer (same), computer motherboard (same save for AC power, but the 
power supply was unaffected.)

I am a firm believer in disconnecting all cables and wires, including ground 
wires.  I have never had lightning damage when I do so.

We now live in Florida, lightning capital of North America.  The only 
lightning damage I've had is to a cable modem, and a K3 disconnected from 
aerials and power but not my computer.

Monty K2DLJ

So it would be my guess that the important wire connections to
disconnect are the ones that go outside the station:  all ac electric
connections, all antennas, all telco/internet connections.  Interface
wiring between pieces of equipment in one room should not be an issue
as long as the "outside" world is disconnected. That should lessen
the number of cables to disconnect.

If you include a lightning protection system in your home and radio station
construction, be sure to perform regular follow-up inspections of the
system.  As lightning protection systems age and corrode, or new
construction or changes are implemented, the system needs to be tested and
evaluated to be sure it can perform when required.

A ham friend does inspection of lightning protection systems
professionally. I got some first hand education when a NWS forecast office
had lightning damage. They discovered after the fact that the building and
tower protection system had corroded and needed upgrading. It was a costly
experience.

My mother lost several items worth thousands of dollars to lightning damage
just a few weeks ago in Oklahoma.  The lack of lightning protection was as
much a factor as the lighting.  Many of the items were connected via UPS
boxes. UPS's cannot substitute for a lightning protection system.  As has
been noted by others, she cannot disconnect everything in the house.
Sadly, she had just settled an ins claim for hail storm damage.  I don't
think her insurance company is very happy with her.

That indicates you either have a faulty 3,5 mm socket on the KIO3 or 
maybe not the right plug (US vs. mm diameter, there was a discussion 
about that a while back). The latter might well be the case as you 
certainly had to use an adapter as the front panel socket is 6,3 mm. I 
would try a different 3,5 mm plug first to rule that out. Good luck!

I have had several instances of nearby impulse damage and surge voltage 
on the AC line.  It could have been very expensive but for insurance.

I would put in a plug for either the ARRL or Ham Radio Insurance 
Associates equipment insurance.  HRIA will cover up to $5000 in losses 
for $136/yr including Mechanical Breakdown.  The two policies are very 
different so review them to decide which is best for you.

If you love your K Line as much as I do, you'll get it insured.

There is some protection to AC surges, look here:

http://www.deltasurgeprotectors.com/products.cfm?sortit=1&Category=Lightning%20Arrestors

I have one on my service entrance.  Does it work?  I can't prove that, but 
anecdotal evidence seems to indicate it does.  Some years ago a direct hit on a 
house in the next block caused a fire.  I know of a TV and a control board in a 
dish washer that were fried, one next store and another across the street.  
There may have been more that I'm unaware of. I'd like to think it worked here 
though.

It boils down to risk assessment too.  That is a personal decision. I've got 50 
years of motorcycling and know others that would never get on one because they 
are so dangerous.

Those look exactly like what we had 3 of in the circuit breaker cabinet in the house and condo in St Pete. ?A really "direct" hit will blow them up, but hopefully after they have sunk most of the energy. ?One big snap, and they are done.

Then again, there are more joules in a lightning strike there than they can handle. Lets face it.. the Lightning "lab" that was set up north of Daytona had 6-10 foot long glass sculptures under the tower they put up there... Anything that can turn that much sand molten is more energy than a MOV can manage to make go away easily... Rather stunning forms in various colors in the 'brown' areas of the spectrum... You can see how the lightning bolt spread after getting into the sand.

Hi Bill,

         No issue with that.   In my mind though there is a big difference 
between  "surge" and "strike".  These may have protected some guys stations 
here, and mine, but a direct hit on my house and for sure all bets are off.

         I learned of these from an electrician that swore buy them from his 
experiences on oil rigs off the coast of Louisiana.  They get hit with real 
"strikes" all the time  But they do have a pretty good ground and that must help 
a lot too.

         The real world verses the ideal world. Should I spend $3K on a ground 
system to possibly protect a $7.5K ham radio station?  I have second thoughts on 
that aspect too.   I do think that one of these is a better investment than a 
couple of $20 outlet strips that some rely on.

         All I have lost here was a telephone modem card years ago.

         My best hope is that those on this list who have not seen these or 
other brands may look at them and think that they are not a bad idea.

73,
Bob

Well, I know there is an AA size Li-ion battery, as I have them in my You 
Kits FG-01 Antenna Analyzer.  It lists the 18650, but I see that's a 19 x 
67mm battery.

14500 is 14 x 50mm, so it is the AA sized one.

I know I have used the 18650's as well, as they have lots of current

Unfortunately, those are NOT AA size cells.  18650 cells are much larger.

Barry - I've been playing around with a RemoteRig at K4VV, where Mike W0YR
had set up remote operating using VNC and Mumble/Skype for audio. The
performance of the Internet connection there (which is wireless) is pretty
bad - audio dropouts making CW essentially impossible for any real contest. 

On the pingtesting, the latency sometimes is in the 45 ms range, sometimes
in the 150 ms and occasionally even longer. It usually looks fine if you do
a single pingtest, but do a ping test of 100 pings and you start to see the
problem.

So, I tried RemoteRig and with highly variable latency (high jitter) of the
connection, the RemoteRig audio is no better than what we were getting on
Mumble. The rig control works much nicer than the VNC approach, but the
Internet connection just won't support usable remote audio for CW in a
contest. For RTTY and SSB, good enough - but not for CW.

The parameters you can change in RemoteRig include a lot of buffers and
packet size changes. You can change them independently for the TX audio and
the RX audio. I ran a test on the air with Shin JA1NUT, since he is a CW
"purist" - he said my CW was odd, as he called it "every now and then you
have a 'brainstorm'" - the variable latency would cause some CW sending
buffering apparently. I could improve that on the TX side, but could never
get the RX audio usable over that connection.

So, now Rick AI1V is working with the wireless ISP to see if we can improve
the Internet performance. As the folks from Microbit put it "RemoteRig can't
replace lost packets."

By the way, there is a beta version of the K1EL WinKey Remote software that
gives you sidetone at the local WinKey - we've been using that to get around
having to always do keyboard CW with the remote N1MM via VNC.

For control of the K3-line I don't think jitter and latency of the IP connection generally is a big problem.
The Elecraft software for remote control of the KPA500 and KAT500  is very user-friendly.
The difficult part for a CW operator is in producing nice CW and in obtaining a  good quality CW audio.
I have used RC for many years and think I have quite some experience for CW but very little for SSB.

I have been using K1EL Winkey Remote for a while and it's my impression that it is performing very well (basically similar to using a keyboard). It connects two winkeyers over IP and is described on K1EL website.
Whereas I have heard quite many RemoteRig CW signals that sounded "odd" with occasionally dashes being way too long, I think I can truly say that a solution based on two linked Winkeyers will not have that problem (but it might have other problems).

If someone has made a thorough comparison I would be very interested.

There is a fundamental difference in the way the two solutions operate. The Winkey Remote is locally decoding and sending the character across the IP as a decoded character which is converted to a CW character in the Winkeyer connected to the rig.
It will therefore only transmit a valid CW character (character set defined by K1EL). If you send an illegal character (by mistake or by sending some national special non-recognizable characters), the Winkeyer will output nothing but just writes an asterix in the decoded window. The keying will be indistinguishable from "keyboard CW", which may sound boring for some. If you keep ahead in the buffer, you can only insert space between characters (one space element) and between words (three space elements). If you want to insert a bit more space e.g. between sentences,  you will have to let the buffer go empty. With some training you can make it sound fairly nice. And it gives you a good feeling of using a paddle for CW and of course the flexibility having eyes and one hand free while sending CW.

I use an USB- Winkeyer in the shack (connected to a notebook) and a Winkey-compatible keyer from G3ZLP (half price). The solution is true low cost - unlike the RemoteRig. I have operated from OX-land with a ping time around 120 msec and from various places in OZ mostly with ping times about 20-30 msec. There is no big difference. The biggest contribution for the delay in CW comes from the decoding in the local Winkeyer - it is close to half a second and a bit annoying if you encounter a very eager/impatient  CW operator. It is not for true QSK operation (even if you with the K3 can listen through your own sending). Maybe RemoteRig is superior in that respect.

For the audio I use IP-Sound (which connects over a VPN) and can operate from 8 kbit (GSM or PCM coding) using about 16 kbit/s with a fine audio quality for CW. Much better than Skype.
My friend Steph F5NZY says he has good results with using the VoIP in Teamviewer. I use Teamviewer for access (rig control) to the shack, but I do not get acceptable audio from Teamviewer VoIP.

If the internet connection is such that you have drop-outs of the audio in Skype, I think you better forget about using any remote solution.
I would be pleased to be proven wrong.

I have no financial or other interest in any of the products mentioned above.

Emne: Re: [Elecraft] How reliable an internet connection is needed for A K3 remote to work well?

Barry - I've been playing around with a RemoteRig at K4VV, where Mike W0YR had set up remote operating using VNC and Mumble/Skype for audio. The performance of the Internet connection there (which is wireless) is pretty bad - audio dropouts making CW essentially impossible for any real contest. 

On the pingtesting, the latency sometimes is in the 45 ms range, sometimes in the 150 ms and occasionally even longer. It usually looks fine if you do a single pingtest, but do a ping test of 100 pings and you start to see the problem.

So, I tried RemoteRig and with highly variable latency (high jitter) of the connection, the RemoteRig audio is no better than what we were getting on Mumble. The rig control works much nicer than the VNC approach, but the Internet connection just won't support usable remote audio for CW in a contest. For RTTY and SSB, good enough - but not for CW.

The parameters you can change in RemoteRig include a lot of buffers and packet size changes. You can change them independently for the TX audio and the RX audio. I ran a test on the air with Shin JA1NUT, since he is a CW "purist" - he said my CW was odd, as he called it "every now and then you have a 'brainstorm'" - the variable latency would cause some CW sending buffering apparently. I could improve that on the TX side, but could never get the RX audio usable over that connection.

So, now Rick AI1V is working with the wireless ISP to see if we can improve the Internet performance. As the folks from Microbit put it "RemoteRig can't replace lost packets."

By the way, there is a beta version of the K1EL WinKey Remote software that gives you sidetone at the local WinKey - we've been using that to get around having to always do keyboard CW with the remote N1MM via VNC.

Here's some real-world experience from the three of the six remotes we
operated this past weekend from WRTC:

Our Network at WRTC HQ: Either 100/9 Mbps WRTC-only or 20/20 Mbps shared
with the hotel network.

PR1T: ~384 Kbps using multiple technologies

Typical ping time:  170-190 mS   Number of routing hops to PR1T:  >30 (!)
Typical jitter: less than 20mS

How it worked:   We obviously had some  router issues between us.  When it
worked, it worked very well.
However, we would have dropouts where we would loose communications
completely between the sites for 5-30 seconds.
We kept a ping window up all the time so we could test.

The RRC boxes allow you to adjust CW sending so that it sounds normal on
the other end.
In the PR1T case, we used the K3/0 mini for all the audio and rig control,
but we used TeamViewer to operate N1MM remotely.
We used N1MM to send automated CQs and exchanges... this worked well, as we
were sending keystrokes only.

SK9HQ at SK3W: ~284 kbps asymmetric DSL

Typical ping time:  170-195 mS:  Number of routing hops to SK3W: ~15
Typical jitter: lless than 10mS

How it worked:  Very well.   We could send CW from the RRC locally, and it
sounded good.  I adjusted the RRC to take the
transit times into account.  We also used TeamViwer to control WinTest
locally at SK3W (easy, and it also gave us all the
local station control interfaces at SK3W)

W1VE at K2LE/1:  1.5/.7 Mbps  asymmetric DSL

Typical ping time: 50-55 mS; Number of routing hops to K2LE/1: ~10
Typical jitter: less than 10 mS

How it worked:  Flawlessly.  We networked N1MM over a VPN; Andy was at his
staiton in Vermont, and the second
operating position was at WRTC HQ.   All CW was sent from the remote.

Note that in all cases, we were able to run very high rates (>200/hr on
both CW and SSB); being remote did not affect the
ability to make fast QSOs.

>From prior experience, I can tell you that attempting to run RemoteRig and
a K3 over Multipoint-to-Point Wireless ISPs is very, very difficult.
In this case, you are on a TDM half-duplex connection, and there is HUGE
opportunity for dropouts and very high jitter. (which is going to be
a killer).

If you are trying to remote to a mountain top, find someone (like another
ham) who has high-speed (Fiber or Coax), and run a point-to-point
link on 5 GHz...  This can work very well, and there is a lot of cheap gear
out there to let you get the job done inexpensively.

For portable operation, 4G LTE cellular hotspots/modems work very well --
as long as location is fixed.  I've tried it mobile ( from New England)
and it is so-so, though we have a lot of mountains in New Hampshire.

Bottom line:  RemoteRig and K3s run very well over pretty low speed
connections.   Just make sure jitter is low and fairly consistent.  Latency
can
be fairly high, but you must adjust settings to compensate on CW.

Subject: [Elecraft] K3: Question about data modes...
Message-ID: <1405519402.16537.104.camel@nostromo.NK7Z>

Hi all,

What EXACTLY is the difference between "AFSK A", and "DATA A".  

Here is why I ask:

In AFSK A Mode:
While using MixW, and looking at the MixW screen, and in USB on the K3,
as I tune using the knob, the MixW screen shows the signal stuck to a
frequency on the top calibration marks on MixW.  The signal never moves
from the frequency indicated on the MixW software in the waterfall.

In DATA A Mode:
All settings the same with the exception of switching from AFSK A to
DATA A.  The signal moves relative to the frequency marks on MixW.  i.e.
if the signal started at 14.0000, as I tune the knob, MixW tracks the
frequency, moving the scale above the waterfall, while the signal
appears to move independently of the waterfall calibration marks...  

I have tried REV sideband on the K3, and the same thing still
happens...  

Is there a resource I can read telling me EXACTLY what each data mode
does?  I have KE7X's book, and that does not explain why I am seeing
what I am seeing...  At least not to me...  I am putting my macros
together, and need to get my head around EXACTLY what the two modes do,
as they set up the radio.

Gerry - How does one measure jitter?

All - We have the CW issues worked out, using a VNC window and having the
transmitter connected directly to N1mm, rather than trying to send CW iover
the network.

My remaining question is - in the presence of a somewhat flaky Internet
connection, for whatever reason - latency, jitter, etc. - is there any
problem with the K30 control of the K3?  For example, when turning the AF
gain or tuning knob, will they follow well, or will there be dropouts of
radio commands, hinder reliable operation?

TU,
Barry W2UP

In simple terms:

AFSK A is LSB, AFSK TX filter (MENU: AFSK TX) is available and
controlled by PITCH (Mark), audio input uses data selection.
TX and RX EQ are disabled.  Receive dual tone (dual peak) filter
is available.  Frequency (VFO) display reflects *MARK*

DATA A is USB, AFSK TX filter is not available, default center
frequency is set by FC (shift), audio input uses data selection,
TX and RX EQ are disabled.  Receive dual tone filter (dual peak)
filter is not available. Frequency (VFO) display reflects *carrier*.

David,

AFSK A is optimized for use with RTTY.  It defaults to LSB and the 
frequency displayed is the frequency of the Mark tone.  The latter 
feature does not make too much sense to me when using a waterfall 
display, but it makes a lot of sense when using narrow filters and 
tuning to a RTTY station with the VFO.  If one arranges  sked with an 
RTTY station, the sked frequency will normally be given as the mark 
frequency.

Data A is the best to use for those soundcard data modes where a 
waterfall display is used.  It defaults to the usual USB used for many 
data modes.  The K3 frequency display is the frequency of the suppressed 
carrier.

73,
Don W3FPR

Joe,
Is there something else that might explain the actions of the signal in
the waterfall of MixW?  

I have tried DATA A in REV sideband, (I thought that would fix the
issue), and the signal does not stay pinned to the same frequency under
the MixW calibration marks...  As I tune up, MixW moves the calibration
marks, but the signal moves in the opposite direction...  This happens
no matter if in REV or not, In DATA A, it never tracks correctly.  If I
reach over and switch to AFSK A, it tracks as expected...  Stays pinned
to the frequency marker, which is moved as I tune.

I would expect that only changing to REV would correct this, but it does
not.  Hence why I question my understanding...

Subject: [Elecraft] K3 receiver troubleshooting
Message-ID: <COL126-W230141FA980942CFD527F2CEF70@phx.gbl>

Yesterday I posted about extremely low receiver sensitivity on my K3, at both the main antenna input and the receive input on the KXV3 module.
A buddy helped me this morning and we found the problem.

In doing the circuit diagnosis, and we are both somewhat experienced in technical matters, we became very frustrated with the Elecraft schematics.  We found it very hard to signal trace through all the plugs and jacks.  Signal points seem to end with a label, with no indication of where that label reappears.  And although we found the problem it wasn't because we had the info we needed.  For example, we never did find a schematic of the KXV3 module.  It isn't in with the installation docs for the module, and if it is in among the K3 schematics it must be disguised somewhere.

We found it was effective to take a probe from the signal generator and inject it at various points, looking at the IF output on a spectrum analyzer.  But we had to do some guessing.  Like is there really an amplifier on the IF output in the KXV3 like the block diagram shows?  I don't think so.

Thanks to all who offered helpful suggestions.  They were all via email - you notice there were no helpful postings on the reflector.  Anyway, it's working again and I'm a happy camper.

Barry,

Do a long series of pings (ping address -n 500 will let it run 500 times)

Jitter is the difference between ping times  (100ms ping and 120ms ping is
20mS jitter)

"My remaining question is - in the presence of a somewhat flaky Internet
connection, for whatever reason - latency, jitter, etc. - is there any
problem with the K30 control of the K3?  For example, when turning the AF
gain or tuning knob, will they follow well, or will there be dropouts of
radio commands, hinder reliable operation?
?"

Yes, everything will go to hell if internet connection is bad... knobs
don't react fast, display does not update fast, etc.
However, don't panic.  Unless the problem persists, it will go away quickly.

Hint: Don't turn knobs like audio or power fast.  Each pulse from the knob
is sent as a UDP packet... If you turn too fast based on the connection
speed, the vlue won't change much.  Turn slowly and it will update
regularly.

I found that with our PR1T connection, screen updates and knob turning
would recover, unless the connection went down for a long time, and I get
that DANG LOUD
SIT tone in the remote.   If I get that, I just cycle the power on the
front panel of the K3/0 mini, and it ususally comes right back.

? Since we are talking about the data modes. W1AW/4 was on 15m PSK31 this morning. Nice signal here in MN. I had good copy and was on his freq using 31 bps PSK D and I called and called. Much of the time no other callers. I called maybe 20min and gave up. I came back maybe 35min later called a couple times .. no answer. SO I went to USB, loaded Multi PSK .... bang one call QSO. 


? I see when I am in Data PSK mode the K3 shows USB ... if I go to ALT it shows LSB and REV, so looks good to me. 


? Any experience out there that might have some guesses as to what was going on? Just seemed odd.

George,

If you operate mostly on battery, use the 2ma. option, otherwise I would 
use the 6 ma. for its extra brightness - but best is to install it 
initially for 2 ma, and then look at it to see if you think it is bright 
enough.

I don't think there is room for a switch.

73,
Don W3FPR

I'm late to join this thread, but was curious so read a couple before
deleting.  What I bring up below may have been discussed before.

I'm not much of a network person, but I believe UDP packets are tossed
out with no error correction at all (like unproto X25 packet).  Having
lived in a packet loss environment for a long time (years) and running
IRLP, I can tell you that when a packet it lost, it is lost.  The
command, audio, whatever, will be lost and have to be repeated in order
to get it through.  As I said, this may have been discussed before and
I'm sorry for any repetition it brings.  It also causes pretty bad holes
in the audio if it is sent UDP.

The flip-side is that use of a "reliable" protocol, such as TCP, which
detects and retransmits dropped packets, causes increasing latency
over time (the more packets get retransmitted, the further behind
"real time" you get). For something like a "real time" audio stream,
it generally better to just accept the packet-loss. The problem of
increasing latency can affect UDP too - some types of unreliable links
cause a sequence of packets to get queued, then all transmitted in a
burst. This causes a gap in the stream, followed by that increased
latency as all of the packets received in the burst, and any
thereafter, need to get played sequentially. Buffering can help to
smooth this out, but the more you buffer, the greater your baseline
latency, which is a big deal for remote operation - e.g. tuning around
the band, looking for CW signals with a narrow filter engaged - if
there's any significant latency, you've already tuned past the signal
before you hear it. It's a tricky problem area. My personal software
solution uses UDP and a moderately-sized buffer, and when the buffer
builds up to a point where the latency is more than I like, I click a
button to dump the contents of the buffer, and return me to
low-latency.

Hi Joe,
I was thinking that as well, but MixW is using USB.  As a test I
reversed the sideband by pressing the mode until I saw REV pop up.  I
would have expected that to correct the issue if the software were on
the wrong sideband, but it just makes it fail the opposite
direction...  

My belief tells me that I should be able to reverse sideband on the
radio, and reverse sideband on the software and it should still work...
Is that a correct understanding?  What drives me nuts is that I have it
working for CW and RTTY, both use LSB...  I use DATA A for and USB on
the radio for JT65 and that works.  My only issue is with PSK...  Maybe
because PSK works in USB or LSB the software, (MixW), defaults to LSB,
no matter how it is set.

I note you did not post what the actual solution was. You are the only
source for that information.

Just a reminder that the Elecraft reflector is not an Elecraft
technical support email address. While Elecraft employees may post
here from time to time to answer email on the reflector, there is no
guarantee that Elecraft employees or Elecraft owners will answer a
particular question. For Elecraft help from Elecraft employees one
should use support at elecraft.com or k3support at elecraft.com with issues.
These emails are answered during normal business days and hours.

Reflector readers are not under contract to Elecraft to answer posts,
nor is there a requirement that someone who does answer a reflector
post must do so on the reflector.

Personally, I rarely offer help across this or any other reflector any
more, because it is too hard to keep track of helping email threads. I
set up a new folder with an intelligent name for a corresponder with
filters to put new mail from him/her in that folder. Not putting that
help conversation on the reflector also avoids trash talk (both on and
off reflector) from a certain kind of reflector user which otherwise
is a real and ugly disincentive. I will sometimes convert to telephone
conversations if the writing becomes too complex. All that goes on
without a clue on a reflector I was there.

I would say that it's up to the person who asked for help to post the
eventual solution on the reflector. This makes the answer compact and
only relates the answer that actually worked. And it cuts down on
noise when someone is later searching archives for a solution.

Clearly those who answered you off-reflector saw the post on the
reflector and so it would seem to me that the Elecraft reflector
worked well. But email correspondence is no match for a technical
buddy with test equipment working right there with you on the physical
equipment. :>)

As to the schematics, using the current Adobe Reader to display the
schematic PDF's, the search function will find all the occurrences of
a wire label very quickly. I have found Elecraft schematics **very
easy** to navigate and use with Adobe Reader. I decidedly prefer
Elecraft schems to the microscopic lines in the paper schematic of my
FT1000MP, and having to pencil trace a wire as it snakes around the
page.

To find the KXV3, bring up the June, 2010 version of the K3 schematic
PDF with a current Adobe Reader. Hit CTRL-F. This will bring up a blue
"find" window at the upper right. Type in kxv3 and hit <enter>. You
can repeat the search to see every instance of the characters kxv3
(case insensitive) anywhere in the PDF.

Huge help in chasing stuff in PDF schematics.

73, and glad you found the trouble.

Message-ID: <C36E361BF7D74DDF8004993DA9FA8315@James>

Barry and others,

 

I have been following the discussion and want to add the description of a
problem and its solution that I encountered with my remote operation.

 

My set-up:

 

Control site:  Manhattan, New York; k3/0 mini to RemoteRig with wireless to
WiFi router to Cable ISP (ping 10ms; 15Mbps forward; 1Mbps return); more
than 25 strong WiFi networks in range

 

Radio site:  Town of Clinton, NY (rural); K3/100 to RemoteRig with wireless
to WiFi router to cable ISP (ping 16ms; 55Mbps forward; 25Mbps return); only
my own WiFi Network in range

 

Parameter settings: All settings of the RemoteRig and Elecraft equipment at
both ends were without any exception at the values recommended by Microbit
and Elecraft in the manuals

 

Problem: Dropped packets resulting 0.1 - 1 sec audio drop outs both ways and
messed up CW; worse during business busy hour (5 - 6 pm) and at night from 8
- 11pm

 

Solution: The problem is clearly not caused by line speed or ping time. At
first I though the problem might be congestion at the cable node in the City
(400+ business and residential users on the fiber fed node), but the cable
company convinced me with tests that I witnessed that this was not the
issue. Then I talked to some folks about WiFi issues. What I learned is that
most WiFi equipment as-delivered is set for channel 6 as default and most
users leave it there. I checked my router in the City and found it was on
channel 6.  I changed my router to channel 8 and the dropped packet problem
completely disappeared and CW is just fine. So the problem appears to have
been something we hams are all familiar with - QRM.  My suggestion is, if
you are having a dropped packet problem and are using WiFi in a dense WiFi
environment as part of your remote system, try changing your router WiFi
channel as a first very easy step to solving the problem.

 

73,

A while back we tried Remoterig with a Kenwood radio and the CW generated
was poor on the other end.  This was presumably from dropped packets and or
latency issues (Comcast on one end and a terrestrial microwave connection on
the other end).  Some dits/dahs were lost and others were prolonged, due to
the lost stop signal.  My understanding of the remoterig protocol for CW is
it's not very robust, with no error correction or ACKing.

 

We got around the CW problem by using a VNC and the CW is generated at the
host end within the VNC window, using N1MM, directly keying the radio.

 

If we were to use a K3 and K3/remote for the radio, would there be potential
radio control issues due to the flaky internet connection, or is there
redundancy and/or error correction built into the Elecraft remote protocol?

I am a network person.  When you use UDP, it is up to the protocol layer 
above to handle dropped packets.

For example, a volume knob should send a value, not just +1 or -1, and 
in a remote environment, it'd be good to send a full set of "settings" 
periodically.

... or each UDP command could require an ACK via UDP.

Or a few dozen other answers.

For voice, where latency is more important than dropped sound, you 
usually don't try to replace the lost packets.

Keep in mind too that WiFi channels overlap quite a bit.  If the problem 
is WiFi activity on channel 6, you'd have to go to 3 or 9 to be 
completely clear.

I assume the setup will be about the same as for other Pactor modems,
like the PTC-IIIusb.

My problem is to get out enough power. With MIC gain turned fully up,
I only get out a few watt. Any ideas?

There are only actually 3 wifi channels at 2.4ghz for 20mhz spacing, and
they are 1, 6 and 11.

By using any of the other numbers you are overlapping the adjacent channel.
 Whey they let you pick 2,3,4,5, etc., is beyond me.

By using 8, you will be getting interference from both channels 6 and 11,
so I would recommend that you use 1 or 11, or, better yet, move to 802.11AN
and use the 5Ghz band and then you can also take advantage of 40Mhz
bandwidth, full 3x3 Mimo and much better speeds of over 300Mhz.

I would also make sure you lock down your current router to 802.11G or
802.11N if you can.  If anything else joins your network and it is B, it
drops down to the old B speeds.  In fact, all your router has to do is hear
other traffic (your neighbour) and a B device connected and it will drop
down that speed.  Surprised that your neighbours can actually impact your
bandwidth by not being connected?

The 802.11 spec is designed to play nice with your neighbours and not QRM
them.  :)

I think you mean channels 1, 6 or 11 to avoid overlap on the 802.11 2.4 GHz
band.  Other WiFi bands may differ.

Fortunately, this is one group I DON'T have to explain to about
overlapping frequencies.  See the picture--it will make it clear as day.
 There are fundamentally (in the US) only 3 frequencies that correspond
to channels 1,6, and 11.  In Europe, you also get a 4th frequency on
channel 14.

Channels 12-14 are only legal outside the USA.

Another solution if your hardware and router support it is to move to 5ghz. Much less chance of interference but wireless range is less.?

Message-ID: <53C71FF1.6060206@storm.ca>

It's been quite a few years since I used MixW, but here goes:

1. Last time I tried it, MixW did not understand the K3's digital 
sub-modes. Basically it acted as if they were all the same (either FSK D 
or AFSK A), i.e. on LSB. Even when I put the rig in DATA A, MixW still 
acted as though the radio was in LSB.

2. If the waterfall is in Auto mode, MixW recognizes when the rig is in 
REV, and automatically adjusts its sideband to accommodate the switch. 
In other words, if it was on the wrong sideband without REV, after 
entering REV MixW automatically changes its sideband so it will still be 
on the wrong sideband. The solution to this is to take MixW out of Auto 
mode and force the waterfall to be in USB regardless of whether the 
radio is in REV or not.

3. One other problem is the frequency offset: in FSK D and AFSK A , the 
K3's dial displays the Mark frequency, whereas in DATA A it displays the 
suppressed carrier frequency. Therefore you may need to supply a 
frequency offset to get MixW to display the correct frequency.

My recollection was that I was able to configure MixW either to work 
correctly in AFSK A/FSK D, or in DATA A, but not in both, at least not 
without making configuration changes when I changed data sub-modes. I 
have no idea whether the current version is any different, but your 
experience suggests that it may still have this problem.

Subject: [Elecraft] How reliable an internet connection is needed for A
 K3 remote to work well?
Message-ID: <CALcvumPEhWOFVMU+CPx_vus4UqsyMShM6_uo=n=rmZB1fWBBrw@mail.gmail.com>

RemoteRig/RRC uses UDP (Realtime Data Protocol) for Audio, and I'm sure a
lot of other stuff.  This is the best mode for most of what we are doing
with remote ham radio.
Signaling is modified Session Initiation Protocol (SIP), also UDP.

All that you need to know is that it will do fairly well over pretty rotten
internet connections.  Speed itself, as well as bandwidth, are important,
but latency and jitter are what
is going to play havoc with a quality connection.  If you are doing remote
in-country in the US, you are not going to see many issues (unless you are
on a wireless Multipoint-to-point
network or any other network using TDM/time slicing techniques.).

I'm amazed at how fast the Microbit gear recovers after a network loss.
 They have done a good job.

The K3 - RRC combo is awesome for remote!

Guy, thanks for the tip.  I will give it a try.
A relay in the kxv3 rev 2 failed, an Omron part.  It is now obsolete.
Elecraft sells a new rev 3 version of the kxv3 for $88 as an upgrade.  You trade in your defective module. 

The failure occurred during the night that we had electrical storms so I assumed some solid state part in the rx path had probably gotten zapped.
But we could inject a weak signal after the kxv3 and hear it, but not before it.  Of course that sounds like a simple diagnosis, and it is when you are reading the final outcome, but not when your rig is spread out on the bench.

I found the problem.
Increased the settings of PSK/FSK Level in RMS Express TNC Setup to 600.
Now I've got full power out from the K3.
Guess I'll have to investigate proper MIC setting in order to avoid
flat-topping etc.

All this talk about the K1 backlight led me to look back at the K1 order
page. There is no option for a 4-band version, nor for the KFL1-4 4-band
filter module itself. Is this an oversight, or has the 4-band board been
discontinued? If so, when and why? Also if so, then the K1 description page
should be edited to remove reference to the "new" 4 band board... or at
least explain that it is no longer available.

P-T,

If you follow the instructions frequently given on this reflector, you 
will have proper power control and no flat-topping.
For soundcard Data modes, monitor the audio input level on the ALC 
meter.  You should have 4 bars illuminated with the 5th bar flickering.
The first bars of the ALC meter do not actually indicate ALC - the onset 
of ALC is at the 5th bar, so the lower bars are used like a "VU-meter" 
to aid in adjusting the audio drive level.\

The closed loop method of power control used by the K3 requires that you 
fully drive the audio and use the power knob to set the desired power 
output.  Attempting to control the power with the audio drive will 
result in "power hunting".

Hello Gentleman,

In fact, I was annoyed by SCS modem.? I sent Martin of SCS modem emails and asked?him about the connection between their modem and K3 or KX3.? SCS modem's answer was a simply 'no', no information available.? It was a very frustrated experience.? Perhaps, SCS modem is more interested in marine radio sector.

My original ideas?was that KX3+ Pactor 3 or 4 modem will be a good combination for many communication purposes.

Not sure this will help but I have used SCS PTC-II with my K3.
The modem has both hardware and software adjustments for the mic gain, 
suspect this new modem would too?

Hi Don,

Thanks for your helpful comments.

I've tried to do this adjustment while attempting to initialize a WL2K
connection via RMS Express. However, I find it difficult to adjust the ALC,
since the meter flickers way too fast.

Hi Johnny,

Martin of SCS has been quite friendly towards me. He tried to help me even
if he was on vacation. What more can one ask?

However, I'm a bit disappointed over the documentation for the P4. So far
there is only an installation manual. The full manual with command
description etc. is missing. I had to download the manual for another modem
in order to get info on the command set. And I've not so far found any
information of the misc info that can be displayed on the P4 screen.

But I have a lot of patience, and will wait and see. ;-)

P-T

I use Yamaha CM500 with K3. It is wearing out so I started looking at
alternatives. Yesterday I connected Bose OE ($100).  The sound quality
changed from OK or a bit harsh to very smooth, like from Chevy to Cadillac.  
A pleasure to listen to.

I thought that headphones are headphones and their main differences are
frequencies characteristics, sensitivity + fit. However, with OE the sound
quality is greatly improved. Any idea why?

Seems choosing $40 headsets with $3k radio is not be the best idea. 

If only they had a headset....

Just curious.  What does anyone recommend for a signal generator to use
for this kind of diagnostic process.  I am looking for something fairly
low cost as I hope I won't be doing this very often.

Of curse they are - they're in bed with certain ARRL board members to
take over the CW/RTTY bands for that commercial use (RM-11708).

It may be - but get the KX3 type accepted for maritime service and
use it outside the amateur radio spectrum if you are going to use it
for non-amateur purposes (including maritime e-mail).

Yes, Bruce, it looks like this:


      /T//he K1...A compact, high-performance CW
      rig that _you_ can build./

//

/HF operation is more fun than ever these 
days--five watts is all you need to work worldwide 
DX. That's why we've packed up to four bands into 
our affordable, easy-to-build K1-4 transceiver. 
You can order the K1 as either a four-band radio 
*(K1-4)* or a two-band radio *(K1-2)*.  The new 
four-band K1-4 covers 40, 30, 20, and either 17 or 
15 meters. (All band parts are supplied with the 
kit and 17 or 15M are chosen as the last band at 
build time.) You can also upgrade the K1-2 to a 
K1-4 by purchasing the four-band KFL1-4  module 
and replacing the KFL1-2 in your original K1-2. 
The KFL1-2 two band module covers your choice of 
two bands (80, 40, 30 20, 17 and 15 meters 
available). Combining a K1-4 with an extra KFL1-2 
band module on 80 + (15 or 17M) gives you all six 
bands on your K1! Both module types simply plug in 
to the K1's main board, internally, and you can 
swap either type in at any time./


needs an edit -- unless lack of a 4-band module is 
a temporary situation. Perhaps Elecraft will 
clarify when their day begins soon.

Really? Thought I saw one.  Hmm ... I just took a 
look and it looks like you are right; maybe now 
you have to change out two band modules. If so my 
4-band K1 is now golden.

Perhaps Elecraft is phasing out the K1? Or maybe 
some part no longer available. It's been around a 
while: I built S/N #18 during my K2 "process".

Adding the backlight mod this weekend if it 
arrives in time. And I'm going for the bright 
option: 0.006 Amps vs. 0.010 Amps? 4 mA won't 
shorten my operating time on batteries much!

If you are OK with open back headphones, the Grado SR-60 ($80) has been the best deal in audio for a long time.  You can turn headphones into a headset with the ModMic add-on boom mic ($50).

I presume this is a question about the Grado SR-60. The SR-60e model was just introduced and is out of stock in many places. The list price is $79. I have the original SR-60 model, which was $60 about 15 years ago. I?m on my third set of foam ear pads.

If you are going to spend that much, you might as well get the Proset
K2.  Great listening, comfortable, and constantly great audio reports
from others.

This is sad news indeed. I have built a few K1s, and repaired a few for
others. The 4 band board made for a very capable rig, without the swapping
that the 2 band version requires. A redesign/reintroduction would be nice,
but I imagine it's primarily a business decision, rather than strictly an
engineering one.

Bummer -- and Lisa's exact words from that link 
were more definite and final:

/The 4-band board was discontinued due to a part 
availability issue that was crucial to the 
functionality of the KF1-4. So no, it will not be 
coming back sorry to say./

The 4-band K1 is a really nice, small QRP radio -- 
with 5 Watts. Definitely a better CW receiver than 
the KX1 (4-pole filter, plenty of audio, etc.) and 
a more capable transmitter. Of course, not the 
freq coverage of the KX1 and not as tiny or trail 
friendly, but a very nice rig.

If I had to sell my KX1 or my K1 it would be the 
KX1. My K1 would make a capable 40-30-20-15 qrp CW 
based station, particularly after adding one of my 
audio filters.  KX3 is, of course, a far better 
option and I have one; but it is larger and much 
more expensive -- plus it's not a melt solder and 
wind toroid kit.

And, here I was planning to get a 4-band K1 this fall.  Yes, real Bummer.

So, I figure that I could do one of the following:

     (1)    Buy THREE 2-band K1 radios (saves on interchanging other bands).

     (2)    Buy the Two band option board and get along with 4 bands.

     (3)    Stick with just a 2-band K1.

I am going with the obvious, option (1).  OK, just kidding.  Option (2)  But at first I am starting just with Option (1).  I wonder if there is a science behind the logic in which two bands to choose to go together.

Good for you, Gareth. Building my K2/100 #380 over 
about a four year period as elements became 
available may have been the most fun I've had in 
60 years of ham radio. I'm still updating it 
(pretty much done with that, now) and adding 
things (like the MAB) for more functionality.

Have fun!

Message-ID: <53C812EA.5070205@gmail.com>

I just added a different set of stereo amplified speakers to my K3 #4123.

Yesterday all was ok, if I switched from AFX active to OFF,
my volume levels remained the same, just the sound changed.

Today I was listening with the AFX BIN active (my normal setting)
and then I switched the AFX OFF, and my volume level dropped way down.

If I listen through my headphones, the volume level stays the same.

Have I killed my audio out?

Why would volume still be ok on both speakers and headphones when the 
AFX is active if it the dreaded 'killed my speaker amp IC chip' problem?

Bad news...for those who don't have one.

The K1-4 was my introduction to both Elecraft and purpose-built QRP 
rigs. It's easily in the top 3 favorite radios I have owned in half a 
century. I think Gil called it a cute mini K2 in the link below, and 
that's a pretty good description. It's big enough to operate like a 
"real" radio in the shack. It's small enough to take anywhere. It tunes 
smoothly and sounds exceptionally good. It has everything you need for 
CW and nothing you don't.

The KX1 isn't a good substitute for the K1, in my opinion. It's a very 
specialized rig with lots of compromises for those who need minimum size 
and weight. After the initial fun of a new rig, my KX1 has been sitting 
on a shelf with very little use. Whenever I grab it to go camping, I 
pack the K1 as well "just in case". Then I end up using the K1 the 
entire trip. If I was a backpacker, the roles would probably be 
reversed, though.

Anyway, re: K1-4. I got mine, and I'm KEEPING it. (hi)

The part that has become unavailable is the blue trimmer capacitors that 
are used for tuning the bandpass filters.  That does *not* spell demise 
of the K1, but only the 4 band board.

Yes, sorry that it is gone, but the K1 with a 2 band board and an extra 
2 band board will give you 4 band capability - and you can mix and match 
the 4 bands in any combination of 2 bands that you want. In other words, 
the choices are more flexible than with the 4 band board.

Hi Bruce,

The 4-band module requires extremely low-temperature-coefficient trimmer capacitors because of its narrow-band pre-mix and RF band-pass filters. The last source for these exotic trimmers dried up recently. A redesign using higher-TC trimmers might be possible, but the filters would end up being triple-tuned, which would force the use of SMD components throughout, and tuning the filters would then be very difficult without a spectrum analyzer. 

Sales volume for the K1 has decreased in recent years due to the KX1 (which is smaller and has a DDS VFO), and the KX3 (which covers all bands, all modes, with up to 12 W output and has a much more capable auto tuner, nicer user interface, etc.). So the cost of a redesign wouldn't be recovered.

That said, for the time being we're continuing to offer the two-band version and the other options (KAT1 ATU, KBT1 battery pack, etc.). The K1 is one of our "full" kits, and has a bit of a fan club of its own.

We'll update the website to reflect the change in option availability.

73,
Wayne

Bad news...for those who don't have one.

The K1-4 was my introduction to both Elecraft and purpose-built QRP 
rigs. It's easily in the top 3 favorite radios I have owned in half a 
century. I think Gil called it a cute mini K2 in the link below, and 
that's a pretty good description. It's big enough to operate like a 
"real" radio in the shack. It's small enough to take anywhere. It tunes 
smoothly and sounds exceptionally good. It has everything you need for 
CW and nothing you don't.

The KX1 isn't a good substitute for the K1, in my opinion. It's a very 
specialized rig with lots of compromises for those who need minimum size 
and weight. After the initial fun of a new rig, my KX1 has been sitting 
on a shelf with very little use. Whenever I grab it to go camping, I 
pack the K1 as well "just in case". Then I end up using the K1 the 
entire trip. If I was a backpacker, the roles would probably be 
reversed, though.

Anyway, re: K1-4. I got mine, and I'm KEEPING it. (hi)

The K1 can remember the frequency offset settings for 6 bands, so having 
3 2-band boards is quite practical.  You get to choose which 2 bands go 
together on one board for most of your operating pleasure.

Sam,

Try re-positioning your speakers a bit.  I suspect what you may be 
hearing is acoustical cancellation of the output from the speakers. You 
may not hear that the same in the headphones.

Thanks for taking the time to reply with the details, Wayne. It's a shame. I
(and many others) feel the K1 has some advantages over the KX1, such as the
analog VFO, higher output power, and 4-pole filtering. It's internal antenna
matching unit also offers more tuning range than the KX1. I have also built
a 160m/80m 2 band board for mine. 

I have built and own all the Elecraft rigs, and each has provided great
enjoyment, each has it's strong points.

Time marches own, it would be wonderful if a 4-band redesign solution could
be found, using modern components. Perhaps a pre-built, pre-tuned SMD based
board. But, I imagine the potential sales volume would not justify the
costs. Too bad.

Hi Bruce,

The 4-band module requires extremely low-temperature-coefficient trimmer
capacitors because of its narrow-band pre-mix and RF band-pass filters. The
last source for these exotic trimmers dried up recently. A redesign using
higher-TC trimmers might be possible, but the filters would end up being
triple-tuned, which would force the use of SMD components throughout, and
tuning the filters would then be very difficult without a spectrum analyzer.


Sales volume for the K1 has decreased in recent years due to the KX1 (which
is smaller and has a DDS VFO), and the KX3 (which covers all bands, all
modes, with up to 12 W output and has a much more capable auto tuner, nicer
user interface, etc.). So the cost of a redesign wouldn't be recovered.

That said, for the time being we're continuing to offer the two-band version
and the other options (KAT1 ATU, KBT1 battery pack, etc.). The K1 is one of
our "full" kits, and has a bit of a fan club of its own.

We'll update the website to reflect the change in option availability.

If all the other parts of the KFL1-4 were still stocked, perhaps those
original white ceramic trimmer capacitors could be used again.  I used
my KFL1-4 for two years with those because I did not want to pull and
rebuild the KFL1-4 I built in 2001 after the blue trimmers were made
available.  Yes, I did need to re-align my KFL1-4 about every six months
when the original white capacitors were still in place.

This would be an unfortunate compromise, but I'd rather have even the
original KFL1-4 with those problematic trimmers than use two KFL1-2
filters to get four bands.  I used two KFL1-2 boards (40/20m and 30/15m)
prior to the availability of the KFL1-4.

> Sales volume for the K1 has decreased in recent years due to the KX1
> (which is smaller and has a DDS VFO)...

I greatly prefer the performance and physical form of the K1 over that
of the KX1.  I never bought the BS that some KX1 owners slung around
after KX1 introduction that the KX1 "replaced" the K1.  Did it??  Try
using that KX1 on 15 or 17 meters.  Even for backpacking, the K1 is a
far better radio to cart along if ham CW band RF performance is valued.
The K1 is also less quirky to build than a 80/40/30/20m full-house KX1.

> ...and the KX3...

I believe that there are a number of advantages of the K1 over the KX3
when the extreme sophistication of the KX3 is not required.  The K1 is
much lighter, less bulky, much lower power consumption, and is incredibly
easier to fully master than the KX3 is at even the neophyte level.

I purchased the K1 after seeing its introduction at Dayton 2000, and then
waited the six months for delivery of #175 in November 2000.  After almost
14 years it remains my favorite and most utilized HF ham rig owned in 46
years as a ham.  It is a very very good radio, and I greatly admire Wayne's
design for this classic QRP rig.  Thanks, Wayne.

> So the cost of a redesign wouldn't be recovered.

I've always thought that the K1-line would be the first to be discontinued.
I am pleasantly surprised that the *start* of that is happening *only* now.
It was a very good run for a great QRP radio...those 14 years!  If you don't
have one, get one with a KFL1-2 is still available.

I have had my KX1 for close to ten years now, and it has been a great traveling companion with lots of fun QSO?s.  Two nights ago, I got the rig all hooked up and discovered that no audio was emanating from the headphones. The AF gain control, filter pot, and RF gain control made no difference.  I hooked up the paddle and found that the TX is working fine, and I could hear the side tone through the headphones.

To see if a loud signal had any effect on the KX1 receiver, I put a dummy load on my K3 and sent some test tones, none of which were being received at close proximity.  This problem occurs across all 3 bands.  The antenna tuner is working, and my SWR meter show a perfect match.

Any suggestions as to where I should start troubleshooting?  Tnx.  Len, K6LEN

Several possibilities.

How old are you? How much hearing sensitivity have you lost due to 
exposure to loud radios, loud music, noise at work, use of firearms? The 
audio output stages in Elecraft radios are not designed to produce the 
very high levels needed to overcome a lot of hearing loss, and may run 
into distortion when asked to do so. Wayne designs them this way to 
minimize current drain -- all of his radios are designed to be good 
back-packing radios too.

I worked in pro audio for a lot of years, so I have hearing loss both 
from that and from my years in ham radio. The output stages in my 
Elecraft radios are good enough for my hearing loss, and my expectations 
of what a ham rig should do, but they may not be good enough for everyone.

All headphones are not created equal, even good ones. Their load 
impedance and voltage sensitivity can vary over a wide range. The Bose 
headphones may have greater voltage sensitivity, so the Elecraft output 
stage doesn't have to work as hard.

One thing that all of us can easily do is use RXEQ to get rid of low end 
noise that is of no use for communications, but burns some audio 
headroom. I have RXEQ in my KX3 set to max cut on the three lowest 
bands. Cutting the two or three lowest bands on a K3 would probably help 
headroom by about 2 dB.

      Here's another thought that perhaps one of us could put together: 
give up the internal battery space for a considerably larger filter board 
that could be used to allow room for additional "2 band" style filters 
that don't share components (and, thus, don't need high-tolerance parts). 
No new parts would be needed; the existing 2-band parts kits, and the 
controller from the 4-band board would serve.
      This would also open the door for selecting a completely arbitrary 
set of four bands (eg 15/20/40/80) as the filters would, again, be 
completely independent of each other.
      I'll have to give mine a close look for mechanical feasibility when I 
get home.  -kb7psg

Problem solved!

it seems a brand new 4' long 3.5 male to 3.5 male cable was the culprit, 
when I removed it from the mix, the problem went away. Some how Murphy 
managed to mess with the cable, and my feeble mind. It went from out of 
the box working one day, to weird failures the next day, all in only 8 
hours, sigh.

With the recent 'I blew up my audio chip' thread fresh in my mind, 
paranoia took over, and I feared the worse, due to the loud pop I hear 
when I turn on/off the new amplified M-Audio AV40 speakers, so figured I 
had killed something.

It's still very weird that it would change/fail only with the AFX on/off 
setting?

I will be purchasing/installing the K3AUDPROTMDKT in the near future!

<quote>
Even though the K3?s audio output I.C. has internal protection, a small 
number have failed under extreme conditions such as a dead short across 
the speaker output. This modification adds a 1-ohm resistance to each 
speaker output that tests show prevents failure even under these 
conditions. Some soldering of leaded parts is required to make this 
modification.

Included with all new K3s shipped after mid May 2013.

$9.95 seems like a very cheap price to pay for the piece of mind that a 
bit more insurance against a potential Audio IC failure. My K3 is of 
2009 vintage, so it doesn't have it installed as of yet.

The K1 remembers the frequency display calibration settings (OFS)
for all *nine* HF bands between 160m and 10m (60m is excluded),
and automatically uses the one previously stored for a particular
band when that band gets assigned to a filter board's b1 or b2.

It is worth noting that a small problem will arise if multiple
KFL1-2 boards are built that duplicate one of the bands...such
as a board for 40/20 and a board for 40/15, both for the same K1.
The K1 MCU can remember only *one* frequency display calibration
setting per band.  In the example I use above, one of those two
boards will have some calibration error on 40m unless the 40m
heterodyne crystal frequencies of both filter boards are very
nearly the same frequency.  They'll likely be close enough.

Len,

If you can hear sidetone, the audio amplifier is working, that means you 
can start with the Product detector and/or the muting transistors.
Check the voltage on the gate of Q2 and Q3 - if it is zero (or very 
low), then check U1 pin 6  (the /MUTE signal) - If that pin is also low, 
you may have a bad output from the firmware IC - best check is to 
substitute another firmware IC.

If the /MUTE line is OK, then try tapping on pin 1 of U5 - do you hear 
any clicks in the headphone?  If so, the product detector is working.  
If you have something to measure RF voltage, measure the RF voltage at 
U5 pin 6 - you should have at least 200 mV peak to peak or 40 mV rms (as 
read by an RF Probe).

The next place to check is U6 pin 4 - the output of the Rcv Mixer. If 
you have nothing there, the only components between there and the 
product detector input is Q8 and the Xtal IF filter.

All OK so far, tap on U6 pin 1 (input to the RX Mixer).  If you have 
noise there, all but the front end if the RX is OK.  You can check the 
RF voltage level at pin 6 - like U5 pin 6, you should have at least 40 
mV rms or 200 mV peak to peak.

Still all well to that point - there is a possibility that Q7 is either 
shorted or conducting during receive.  Check the DC voltage on the base 
- it should be zero volts.
If you suspect Q7, it can be removed for receive (but not transmit).  If 
taking it out of the circuit restores receive, replace it.

Good luck,

Howdy Fellow Elecrafters:

OK...it's so obvious even I figured it out.

Notice that we have a KX1 and a KX3??

What happened to the KX2??  Well, read on.

I predict the next new transceiver from Elecraft will render obsolete the K1-4 and KX1 obsolete...it will be called, obviously,  the KX2.

It will be a CW only all band 160M-6M DDS VFO controlled Direct Conversion SDR ala the KX3 but much smaller.

Perfect for field use it will become the new rage of the SOTA and IOTA crowd as well as the QRP community in general that likes to take their rigs out for portable OPS.

OK Wayne....sorry I let the cat out of the bag but at times I am just so darn prescient it surprises me.

So, when can we expect the new KX2 to be available for order??

OK...OK...All of the above said with tongue firmly placed inside of cheek.....but it is just too nice to think about.

I really wonder why the KX2 nomenclature has been skipped???

Am I on to something???  (large grin).

Hi Joe,

Nice try, but...not :)  The KX3 *is* our SOTA/IOTA/FD rig, and we're all busy getting the new options out the door (PX3, KX3-2M/4M) and associated new firmware.

Besides,

I would really be surprised if Elecraft to get a price point for the so-called KX2 to justify it.  I am thinking that it would be priced too close to the KX3.  I already have a KX1 for those times when my KX3 is not my travel choice.  And, I don't need all those bands because my portable operations favor shorter wavelengths.

I would really like to see a 2-meter solid-state amp come out of Elecraft.

Hi Clint,

Nearly all of the KX3's hardware is already stainless steel. We knew the rig would get a lot of outdoor use in places with salt air and Mai-Tai's, both equally corrosive.

The thumbscrews are the only exception; they're steel-zinc, but plated, and we used them on earlier products with good results. Even these would go to stainless steel if it ever became an issue.

Hi Mike,

I appreciate your thoughts on the K1. You're right -- it has a much simpler user interface than the KX3, and lower receive-mode current drain.

But, regarding size and weight:  The KX3 weighs only slightly more than the K1 (1.5 vs. 1.4 lbs), and the KX3 is roughly 30% smaller than the K1 (1.7 x 3.4 x 7.4" vs. 2.2 x 5.2 x 5.6"). New technology and all that....

It is standard to use UDP (RTP) over VoIP for the reasons given by Iain. 
  Over a corporate network, VoIP traffic should have a QoS tagging on 
the IP packets which causes routers to prioritise it. VoIP over the 
internet has always been done for cost, not quality reasons, as the 
whole concept behind IP networks is at conflict with constant rate 
traffic; the telephone industry devised ATM as a packet network for that 
application (although they are now moving to IP, because voice is no 
longer the dominant bandwidth user - but I am sure they will prioritise 
their voice traffic).

RTP has a marker bit which indicates a safe place to dump a latency 
buffer's contents.  Conceivably setting this during tuning would be a 
good idea.  If the remote operation protocol doesn't user RTP, someone 
has been re-inventing the wheel.

As someone mentioned WiFi.  It is generally accepted, in the VoIP world, 
that WiFi and VoIP don't mix because WiFi introduces additional latency. 
  I believe it also does link level retransmission which, means latency 
can be particularly bad if you don't have ideal conditions.

Is it possible to use a keyboard in a standalone configuration to send PSK and CW with a KX3? I am considering getting a KX3 and would really like to use it portable without bringing a PC or needing any other external devices. In looking at the manual (page 28) it seems as if you can only use a keyboard if you have the rig hooked up to a PC.

I am thinking about getting a KX3 and am wondering how good the CW decode is considered to be? Currently I use an SDR rig with CW Skimmer and it works very well but I would like to have a portable rig for car camping and it would be also be handy to have one just in case of a zombie apocalypse or attack by Gojira . 

If anyone reading this uses a NUE-PSK with another rig how does that compare with the KX3 CW decode? 

Last of all how good is the KX3 CW decode in marginal conditions? 

Yeah, I am aware that I really should only do CW by ear but my ears are not so good and I really like using software to decode CW. Currently I have 177 countries confirmed in LOTW with CW Skimmer and my SDR.

There is no provision for connecting a keyboard directly to the KX3. An
external device, i.e. netbook, NUE-PSK modem, etc would be needed to do what
you are asking.

Zack,

The KX3 cannot natively connect a keyboard, but you might want to look 
at the K1EL K42 for CW (not PSK).
The AMQRP NUE-PSK Digital Modem will do the same for PSK or CW.

There may be other products that perform a similar function, but these 
are 2 that I am aware of.
Of course, a PC will do that task easily as well.

And there is also the Ham Central Terminal.  It communicates with the  
KX3 via the ACC1 (RS-232) port on the rig and mirrors the received  
data (CW, PSK31 or RTTY) that is decoded by the KX3.  Internally, the  
HCT will save the most recent 80 characters decoded, and permit you to  
scroll backward to pick up something you may have missed.  It also has  
internal logging capability, as well as additional message memories  
and macros.

The NUE-PSK modem will permit you to save a raw "snapshot" of all  
decoded data on a USB thumb drive as a text file.  But it does not do  
logging.  It does have message memories.

I have both devices, and each works quite well.  They both use a  
standard PS2 keyboard, which is available in compact versions,  
suitable for portable/field operation.  And each device is very low  
power, and can operate over a range of voltages, via external  
sources.  The HCT will also run via an internal standard 9 V battery.

Just a further tip from my side:  the RemoteRig RRC allows ToS tagging. 
It is entered in the advanced settings under "IP Type-of-Service (dec)". 
The manual refers to RFC791 that use this in QoS networks and support 
this function. Entries must be made in decimal.

Unfortunately, I have found no "home" routers so far (at least here in 
DL) that support QoS tags. However, this will for sure help those that 
do have routers supporting QoS.

Hearing loss is an issue but as you write, RX EQ in K3 comes in handy. Many
times especially that many signals are very bassy. 

The Heil EO advantage seemed smoothness, not higher treble. It was like
sitting in a room full of signals, not wearing headphones. A pleasure as
opposed to OK.

Is Heil Proset an advantage over CM500 and close to Bose? In old times, a
microphone made a big difference. With TX EQ, less so.

Hello

The QRPWorks  Ham Central Terminal  and Key Log Go devices support a
keyboard for CW, PSK, and RTTY.  Plus the 80 character LCD shows the
decoded text in all three modes.  These devices also include a logging
capability with ADIF export.  They run on an internal 9 volt battery or
external DC.  There are also stored messages and KX3 Macros to quickly
reconfigure the rig.

I know some folks who really LOVE their Heil ProSet... but I sold mine
after a few months and got the CM500.  For me the Heil was not
comfortable.  It sounded fine, but I think the CM500 sounds just as good,
and is FAR more comfortable on my big ears.

It is pretty reliable and has an amazing number of features. Including CW and
SSB memories + excellent CW decode. 

I traveled with it to many places in the US and outside. Including PA, ES,
OH, SP, 4X,... If anything is to be improved: 

1. Better speech processor (and equalizer). The current one is less
efficient than in K2 and 5 db below K3.  See  COMP_K3_KX3.pdf at
https://groups.yahoo.com/neo/groups/KX3/files. Unless signals are very
strong, I give up on SSB with KX3 when portable. 

2. Have an option for AT to turn off segment tuning. You tune on 14.010, QSY
to 14.030, and AT turns off. Segment tuning is very good for stationary
installations but not with portable antennas.  

Ignacy, NO9E

Both K3 and KX3 come with the TX and RX EQ, I find these radios are very accommodating for many low cost headsets.? I experimented a number of computer boom headsets and currently am using a Panasonic light weight?boom headset costing me only US$20.? In fact, by all means, when you come across some low cost computer headsets, give them a try and you will be amazed to find they are really not bad at all.

I gave up Heil for long time because they are too pricy for me.? I used CM500 which was good but too heavy to be worn for long time.? Therefore, I now settle on some low cost computer headsets.

Do experiment with the settings in TX and RX EQ and you can find a sweet spot.? I can still hear above 12KHz.? My good hearing sometimes does trouble me because I am very sensitive to the artifacts from the DSP audio.

Agreed ... After Bob Heil refused to provide repair parts (mic shell
and element) or repair my original Proset for less than the cost of
a *NEW* replacement from one of the on-line retailers, I replaced it
with *two* CM-500s for less than the cost of a replacement Proset (one
CM-500 is still on the shelf as a spare).

The CM-500 is far more comfortable, its receive audio quality is as
good or better than the Proset, and provides transmit audio every bit
as good as the Proset HC5 or HC6.

I use receive EQ *in addition to* careful, mode appropriate RX DSP
filtering, to roll off both low frequency rumble and high frequency
hiss but I also did that the Proset.

Hi Zack,

Skimmer uses a very sophisticated, PC-based CW demodulation and tracking algorithm, and it works really well, taking advantage of the PC's serious MCU horsepower.

The KX3's implementation uses about 1/1000th as much code space, consistent with the available MCU resources. It can't keep up with Skimmer on really weak signals. So if you were dependent on CW decode to complete QSOs, I would suggest sticking with Skimmer or similar PC applications. You should be able to use these apps with the KX3 via its RX I/Q port (interfaced to a sound card).

Wayne, do you anticipate being able to decode/encode any other modes with

Wayne, do you anticipate being able to decode/encode any other modes with
the PX3/keyboard combination?  JT65 seems to be getting very popular (with
myself included).  Any hope for the future?

This is unlikely as a KX3 built-in mode, but when I get a chance I'll read up on the JT65 demodulation process.

Message-ID: <3FE7B81A-68F8-44D6-AAEB-D8B973FFEE50@elecraft.com>

Hi all,

Since we don't have 4-meter band privileges in the U.S., we sent a KX3 4-meter module to Peter Waters in the U.K. for test purposes. Peter arranged a test QSO on 70.190 MHz (SSB) with another station, as documented in this video:

   http://www.youtube.com/watch?v=t4wziXpaQ5I

Both stations were using a dual-band (6 m/4 m) antenna from InnovAntenna, though I haven't been able to figure out what the model number is yet. Peter describes it as "single-feed, very compact."

For information on the KX3-2M/4M option, see the FAQ:

I normally keep quiet but I have to say my CM500 must be different than
others because if feels cheap, flops, doesn't fit, and it is only a backup
to my original Heil headset with the "4" element.  My Heil feels good, fits,
is comfortable, sounds great, and is what I use all the time on my K3 and
receive many unsolicited "great audio, what are you using" reports.  I was
going to use the CM500 on the back mic connector so I could monitor and
assist new hams get going on the air when visiting my station.  

I do not like the CM500 but it does serve as an alternate when I have to use
it.

I have a MicroTik inexpensive router that supports QOS, and it helps.

However, all bets are off when using far-flung networks.

BTW, I've been exclusively VoIP with my landlines for over 10 years.
 Quality is very good (using the correct provider), and, yes, cost is very
low.  All the major telecoms in the US use VoIP for backhaul from cellular
sites -- it is far less expensive than TDM. I was happy to see RemoteRig
using SIP..  It works well.

I, for one, disagree with this! My CM500 replaced all of my Heil, Sony, and
RadioSport headsets. They are light and comfortable and sound excellent for
CW use. I can wear them for many hours without the 'burned ears' syndrome
that I always get from Heil's. They are inexpensive, but if something breaks
or goes wrong, buying another set is not bank breaking like having to deal
with the other vendors, especially Heil. I'll just keep mine, thank you!

If you want to use QOS tagging, you need to make sure that you 'somehow'
get all the packets tagged in your network.  It is harder to do than it
sounds.  DD-WRT routers seem to do it 'ok' but I have yet to solve it
perfectly.  In my situation, my remote base is at a cottage and it works
perfectly unless there is a gaggle of family each with at least 3 wireless
devices connected.  I has given me lots of real world practice in trying to
tune a network in such a way that my RemoteRig is not impacted.

There is another issue that routers today  have a problem dealing with, and
that is buffer bloat.  In a real time application like VoIP, you do NOT
want large buffers in your routers as that will actually cause you more
problems.  Last I check, and it has been some time now, there were no
routers that handled buffer bloat correctly.

I do believe Meru Wireless (an expensive corporate solution) and Astaro
routers manage buffer bloat reasonably well.

The moral of the story is to stay wired unless you have to go wireless.  A
single box of 1000ft of Cat 5 isn't very expensive and provides a much
better connection in such a solution.

Again, this is from real world experience.

I've actually used powerline adapters when wiring was inconvenient (too 
hard to fish cable through walls, floors, etc.) very successfully.

The ones I have came from D-Link. 
<http://www.dlink.com/us/en/home-solutions/connect/powerline>

They were quite reliable.  I used them in a fairly critical application too.

The problem is its a personal choice. So I find this thread non productive.
Hi-Fi, Pro Audio (my home) & Ham radio. Everyone has their own view...
Its a bit like food.  How do you like your steak?  If its right for you, 
then great.
Yes I have one of the headsets mentioned and I like them.  The XYL 
doesn't. But there again she thinks ham radio is boring.......

Can we give up on Heil versus Panasonic versus Yamaha please.

Subject: [Elecraft] K1-4 4 band version gone?
Message-ID: <20140718201939.ETACT.31541.root@cdptpa-web07>

I am sad about the recent turn of events but not surprised. I bought the K1-2 band right after it was available with an extra 2 band board. When the 4 band board was introduced, I jumped on that purchase. I will probably buy a few of the 2 band boards before they are gone. I don't want any portable style radio as that's not the way I operate.

I have used the K1-4 for several years and really love everything about it. I have earned DXCC on 40 meters with this radio so it does work well. I use an outboard SCAP filter that really makes a huge difference on receive.

I recently retired and did some updating/repair on my K1. I plan to operate this radio a lot more in the future.

When I got my K3 in Oct 2008, my station headset was configured for my TS-870, 
so falling for the hype, I traipsed down to the local ham emporium (since 
closed) and picked up a Heil.

After trying it ever so briefly I couldn't return it fast enough. I discovered 
the CM500 and found it to be outstanding.  As far as I know, I was the first to 
bring the CM500 to the attention of the Elecraft reflector.  Mine has been used 
so much that the cushions are starting to shed a little, so I was thinking of 
buy another one.  Unfortunately, the price in "print 'em by the trillions" O 
dollars has almost doubled since 2008, so I might hold off for a couple of years.

Hello group,

I am very close to pulling the trigger on a KX3 and possibly the 
KXPA100/KXAT100 combo. If I can swing the KXPA100/KXAT100 I think I 
would not option the KX3 with the KXAT3 at this time. But I have some 
questions.

The manual mentions that with the amp enabled but the power set to below 
10W that the amplifier passes the RF through without amplification. If 
this is the case has anyone measured the current draw of the KXPA100 in 
this mode with just the tuner working?

Also, has anyone measured power consumption at less than full power, say 
25W, 50W? Not sure how bad the efficiency gets as the power out goes down.

Message-ID: <53C9A688.2000708@verizon.net>

I am thinking about replacing my ORION II with a K3 as it is smaller 
(much smaller).
My OII will do RTTY (or JT65) at 100 Watts (with the fan option).
What will the K3 do? (I know it has fans, too)
I hear lots of comments about digital power out for the KX3 and heatsinks...
I guess the question also goes for the 500 Watt amp, what will it do key 
down?

btw, 0.5w JT65 is great fun with my KX3...  but I also like to contest 
at 100w.

73, Steve WB3LGC (hope to see you on the RTTY NAQP tomorrow)

Clearly, you've missed the "topic drift."  I don't see "Bose" mentioned at all

Any on ear headphone including the Bose OE is not suitable for long
term wear - particularly when wearing eyeglasses as the pressure on
the ears becomes doubly uncomfortable.

The Bose OE is another "twice the price of the CM-500" and without
a boom mic.

I very rarely use a headset - no reason for it. I have a set of 
powered/amplified Behringer station speakers that are far more 
comfortable to use than headsets. Perhaps some ops have very noisy 
locations for their shacks - dogs, kids, mother-in-law??? RX conditions 
have to be really bad before I will resort to a headset. In my 
experience, if I cannot hear it with the speakers, I am unlikely to 
improve the situation with the headset. Before you drill me into the 
ground for the way I do things, remember - it is the way I do things. I 
am not saying anyone else should follow suit.

Thanks,  You didn't use a brick?
I expected the K3 to handle 100W as there were no comments that I remember.
With your comments it doesn't matter how the 500W amp would work as I 
doubt if I would want to run more than 100W, either.

I also have a IC-706 "100W" rig but it will only handle ~40W RTTY.
No, I wouldn't run 100W on JT65.  The most I ever used with any rig has 
been 20W on the ic-706.

Less then a few hrs. of use. I prefer my Heil BM10's but had to buy them 
when I was down in Florida for the winter and forgot the BM10's at home.

Like new condition, worked great but not my cup of tea .... $35 shipped

It takes 80W drive to get my amp to full output. I've run my K3 
continuously for hours at a time at that level on JT65. No issues at all 
and never even noticed it getting hot.

Mauri AG1LE has been doing some very interesting work with CW decoding in FLdigi using Baysean techniques like what they use in CW Skimmer. You can read about it in his blog:
http://ag1le.blogspot.com.au/

It is still experimental, but looks very promising.

So if you were dependent on CW decode to complete QSOs, I would suggest sticking with Skimmer or similar PC applications. You should be able to use these apps with the KX3 via its RX I/Q port (interfaced to a sound card).

I'm thinking homebrew 4 element cubical quad.? Can feed either on the side for vertical polarization, or bottom for horizontal...? Cheap to build, light weight.? Will work on almost any small rotor, no problems with wind load, and small enough to hide...

The only science I can think of has to do with propagation.  It seems to 
me that 20m/40m would give the best overall opportunity for use hour by 
hour over the course of a full sunspot cycle. Everything else pretty 
much just boils down to personal preference or available space for antennas.

Great first contact!  I love the contact op's sense of humor - wondering 
what the prize for being first might be ... maybe he could receive one 
of those highly coveted, and extremely rare, free E-Brand hats everyone 
is clamoring to get, as a prize for being the first contact on it!    ;-)

Even if you do not like headphones... you MIGHT like a head-worn 
microphone which keeps the mic element in exactly the same position, 
regardless of whether you sit back in your chair, look sideways, stand 
up, or move about your desk area in the shack.  A lot of what is thought 
selective or atmospheric fading is, in reality, unfortunate microphone 
technique, where operators look away from, or sit back from, the 
microphone while speaking.  A head worn mic does not have to have 
speakers attached to be very useful in managing consistent microphone 
input.

Just a suggestion.

Hi Steve,

The K3/100 has two fans. The KX3 has no fans. Apples and oranges.

I ran my K3 on 30 meters RTTY at 100 watts for 2 hours non-stop as an ARRL
centennial station and had no problem. The fan just ramps up to a higher
speed.

I've also run JT65-HF on 6 meters at 100 watts with no visible problem but
of course it's one minute on, one minute off.

73,
Mike K2MK

Hi David,

Page 21 of the K3 manual. Right column under "Programmable Functions". 

You must have accidentally set the M1 button. Been there, done that.

Subject: [Elecraft] Headphones and extension cable - leave plugged in?
Message-ID: <1405784368311-7591390.post@n2.nabble.com>

With my K3, I use the 3.5mm headphone jack on the back and toggle speaker on
/off with a macro programmed into PF1.

As my headphones have a relatively short cable, I use a 6 ft extension
cable.  Recently, the connection between the extension cable and the
headphones become intermittent, so I replaced the cable.

My question - is it better to unplug the headphones from the extension cable
when not in use, as maybe the spring tension inside the female end of the
cable is weakening.  Or, would repeatedly plugging/unplugging it cause more
fatigue in the connection over time?

Hmm .. makes me wonder if a failed fan would 
result in an error message and/or graceful power 
roll off to protect the K3?

I have so much ringing in my deaf ear I never hear

One trick you can try is to cut one fuzzy end off a regular paper "Q-Tip" 
stem and apply a couple drops (or squirt) of DeOxit.  Then poke it into the 
1/8" socket and wiggle it around a bit.  Also, wipe the plug with a similar 
squirt on the fuzzy end.   It may well be that your cable isn't 
intermittent, but just very slightly oxidized.

IMHO, the trouble of removing the plug and plugging it back in is not 
worth the cost of a replacement cable.  I suspect it has worked fine for 
several years.  If not, look for a better quality cable.

In case the problem is caused by contact oxidation, removing the plug 
and re-inserting it several times should wipe the contact area and 
restore it to normal operation.

Hi John,

The two receiver architectures are quite different, and we've had more time to optimize the K3's implementation. But any decoder implemented with a small microcontroller running at slow clock speeds will be a compromise between code space and algorithmic complexity.

---------------------------------------------------


	The plugs/jacks are meant to be connected
	all the time, so it is better to just leave
	them connected.  I believe the usual culprit
	is a break in the little wires inside the
	cable, and not usually the spring clips that
	comprise the jack.  They usually break close to
	where the strain relieve ends.  One can usually
	repair them by cutting the jack off the cable
	(NO pun intended... I assure you) ;-)
	and installing an inexpensive replacement for
	around $1.  The same goes for the plugs on the
	headphones, although the little cables on the
	headphones are typically much smaller gauge than
	that of the extension cable inner conductors, so
	they are much harder to fix than extension cables.

	I have no argument with the suggested de-oxit
	treatment, but in my experience, the jack is
	not the usual suspect (although sometimes the
	jack contacts do break occasionally) and the
	usual problem is a break down the line just
	after beyond the strain relief, so close to
	the jack we suspect it, instead of the cable.

	Shoot, these little extension cables cost
	about  $2 or less at www.allelectronics.com
	so it behooves one  to have several extras
	on hand and just toss them when they go flaky.
	I cannibalize them for the good ends and use
	them for other things when building projects.

	I took extra cables, an extra headset, and
	some odd connectors to my first time at the
	big contest station along with my radio and
	favorite headset - just in case I encountered
	any problems with my gear... and that enabled
	me to provide instant replacement of a
	flaky cable and headset on the most important
	40 meter station, saving them from having to
	effect time-consuming repairs.  I felt pretty
	stud because I was prepared and was able to
	solve the problem in a flash.

	So, buy extra cables and just swap them out
	whenever they go bad, tossing the good ends
	into your "wish box" for use in future building
	projects.
		 			
Just MY take, anyway.

Rather then plug and unplug headphones, I simply wired up a box to take the
output from the K2 speaker jack, and feed it into a switch that in one
position drives the headphones and the other drives the speaker.   This
eliminates wear and tear on both the headphone cord and the headphone jack
in the rig.

I know I'm probably stupid and missing something obvious, but when I turn  
on the sub receiver it is much louder in my right ear than the main is in my 
 left with the AF gain set the same on both receivers and both VFO's tuned 
to the  same frequency. RF gain is set the same on both receivers.  I  have 
one antenna connected to ANT 1 (which then goes to KPA500 then  KAT500).  
The settings are as came from the factory and diversity is not  on.  I've 
looked through the K3 manual and Fred KE7X's book and don't find  anything. Is 
this the 3 db attenuation when signal split to both  receivers?  I would 
think the attenuation would be equal. Firmware is the  latest. Sorry for the 
bandwidth, it's probably something obvious.   Thanks.

Okay here is the solution.
I downloaded this file NetFx20SP2_x64.exe from the MS site and it worked.

Thanks for the help.   Dan



I have been using this without any trouble on WIN 8.1 Pro then,
I installed a new hard drive, and I can not re install the program.
When I go to install  I have a pop up that states. "requires .net framework
2.050727
When I go to install this I get a message that reads "The .NET Framework
4.5 and this update are already installed on your computer."
And then this becomes a circle. I am sure some knows that answer to this. I
would really appreciate some help with this.
My first thought was to uninstall the current version and install and older
version.
As I googled and found a lot of information and warnings
about uninstalling .net framework.
So I need some input on this before I attempt anything and possibly mess up
a fresh Windoze install.
Thank you for your help.
For now, headed out to the park this morning with the KX3 and Alexloop.
Everyone have a great day.

I don't use that mode and generally run no more 
than 40 watts on PSK31 with the K3.

But this statement below "The K3/100 has two fans.

I thought it was "weak signal" mode, not "low power" mode.

I don't think the XYL would permit an array large enough to work 6m EME 
with 10W... everyone has a dream!

The AF Gain dial can also be used like a balance control.  When you say 
they are both set the same, what is probably happening is you have the 
balance control over to the one side.   Look in the Tech Menu for a 
setting called SUB AF. The choices are nor and balance.

If you are in balance mode and you want them to be the same you have to 
set the Sub AF Gain knob to the middle.

SUB AF is set to nor.  I think I figured it out: the Noise Reduction  was 
set differently for each receiver.  When NR is off for both the problem  is 
gone.  I KNEW it was something stupid.  Thanks.   Sorry.

[Apologies if this appears twice ? my first transmission seems to have
gone awry.]


 
When condx are noisy I like to crank the AF gain way up and back the RF
gain way down, and use the RF gain for volume control.  Doing so isn?t
useful for weak-signal work, and it has one drawback (it makes internal
noise more audible, e.g. the TR switching); but it makes CW rag-chewing
much more pleasant when the QRN is high.
 

The KX3 uses a push on the AF/RF encoder to toggle between AF gain and RF
gain.  But here?s the weird thing that happens ? with the control set at
RF gain, the system sets itself back to AF gain when the internal ATU is
cycled.  It?s mildly annoying ? whenever a QSY is large enough to call for
an ATU tune, the radio requires that I manually toggle back to RF gain.
That is, it reverts to AF gain simply by having the ATU cycled.
 

I tried other functions to see if anything else causes this perverse
refusal to keep my preference intact.  The reversion to AF also occurs
when XMIT/TUNE is pushed, when Band+ or Band- is pushed (even after
returning to the original band), and when Mode is changed (even after it?s
changed back to CW.)  It does not happen when the transmitter is keyed (so
it?s probably not stray RF doing this spooky thing), nor when any of the
other controls are switched pressed or twisted
 

I wonder if anyone else with a KX3 has seen this happen ? choose RF gain,
cycle the ATU, and see if the system returns the RF/AF control to AF gain.
 It would be nice to know if mine is unusually cranky or if it?s in the
radio?s genes.  Anyone have an idea why it?s happening?  Or how to keep it
from happening?

You are misinformed. JT65 is NOT a LOW POWER mode, it is a WEAK SIGNAL 
mode. BIG difference. Caps added for emphasis. On VHF/UHF, it is quite 
common to run as much power as you can to work moonbounce, or double hop 
E-skip when the band is only marginal, or tropo. Right now, KH8/W7GJ is 
on a rare island in the Pacific working moonbounce, and both he and the 
stations working him are running big antennas and big power. I run my 
KPA500 on 6M for all modes, including JT65.

Subject: [Elecraft] SWR difference between 2 different K3's
Message-ID: <53CB0911.8070807@rthorne.net>

I have a strange swr issue I'm trying to resolve.

I have two K3's for an SO2R setup, lets call them K3-A and K3-B.  On 40 
meters the swr that the K3 displays on K3-A indicates what is to be 
expected 1.5:1 at 7.001 and 2.0:1 at 7.105, however on K3-B  the K3 
displays 1.0:1 at 7.001 and 2.7:1 at 7.105.

I'm using the same exact coax to connect to both rigs and I'm going 
directly to ant port 1 on both rigs.  Neither rig has the ATU in line 
(K3-B doesn't even have an internal ATU).  The antenna is a 2 element 
40m yagi.

I've used an external Daiwa swr/power meter which agrees with rig K3-A's 
swr  when connected to either radio.

So it appears that the displayed swr on rig K3-B is giving an incorrect 
reading.

Any ideas?  Is it time to calibrate the wattmeter?

Thanks

Yes I guess I was not totally informed. I took the suggestions from the
book and translated it to mean low power.
I read the user guide for jt65hf and it said in part " Running at full
output power is
seldom necessary or desirable due
to the incredible sensitivity of JT65.
Most users find 5 to 10 watts (or less) highly effective and 25 to 30 watts
is considered 'high power'.
Now 6 meter and vhf, uhf I can see high power.
I have a ZS6BKW inv vee at 40 and I work the world on 10 watts.

If I want to use the kat100 to tune it from 20-10meters do I need to alter the balun?  Ive read 10 turns on 2inch pipe or 6 turns on a 4 inch pipe and Ive also read that the turns don?t matter you have to use 21ft.

Hi Wayne, hi K1 friends,

I followed the discussion about the 4 band module and the problems.
I can imagine to design a replacement board with four or even more 
bands in a way, that the problems with the alignment and the components
will be solved. I do not know, if the dialogue to the PIC was ever published
???
Because a board needs to do that dialogue for the bands that are provided.
I would redesign that board and offer it to the "K1 family" as a kit with 
presoldered smd and possibly with ready wound coils so that the handling
for the user could be easier ?

What do you think...... worth thinking about ???

Hi Wayne, hi K1 friends,

I followed the discussion about the 4 band module and the problems.
I can imagine to design a replacement board with four or even more 
bands in a way, that the problems with the alignment and the components
will be solved. I do not know, if the dialogue to the PIC was ever published
???
Because a board needs to do that dialogue for the bands that are provided.
I would redesign that board and offer it to the "K1 family" as a kit with 
presoldered smd and possibly with ready wound coils so that the handling
for the user could be easier ?

I was reminded how capable the K1 is a couple weeks ago at a beach house at
Seabrook Island, SC...  I broke away from family activities for just a
couple hours one night and made solid K1 DX QSOs with Ukraine, Sweden, Italy
and others using just a lightweight 20 meter dipole tied to the corner of
the house and then slung over a big live oak branch.   Spanish moss hanging
on the wire overlooking about 15 square miles of salt marsh... Priceless!

Back to topic... perhaps it is time for Elecraft to start offering some "big
boy" kits that make full use of SMTs and other modern components.  Any
serious ham should have a good digital 'scope, and a hot air solder station
with a syringe of solder paste (which can be bought new for less than $100). 
With the right tools, SMTs are the way to go!

There is a lot of "real estate" available in the K1 enclosure; an updated
4-band board with some cool, new features to retrofit the K1 would be a
great first Elecraft "big boy" kit offering!  (I expect that if Elecraft
takes a pass on this opportunity, some enterprising Internet mom 'n pop shop
will step in.)

Thanks for the reply, guys.  I know the cables are cheap - I just bought
replacements on Ebay $2.39 for 2, including shipping!  Just a pain,
especially when it fails during a contest, like this one did during the IARU
last week.

P.S. Sorry for forgetting to ID in my earlier post  :-)

In the broadcast stations I worked at over the year, the audio patch panels had a lot of activity.. but there were basic ground rules to make sure something 'bad' didn't happen in the middle of a live show..

1) you plug and unplug the connection 2-3 times before leaving the cable hanging.  (Periodically they got cleaned and lubed, but the connections will oxydize over time....

2) you always test the connection with the studio so that you don't have a surprise.

With video cables, it was not as common to have issues, because there was always a plug in the connections for the 'normal' feed. (Video didn't use the contacts in the patch bay to provide the 'normal' connections.

There were some audio cables that were left in place for months in some cases.. Periodically they would get the same "reseat" action to make sure that there was no problem.  (Example: control room reconstruction.)

The sheer volume of contacts and cables in that environment makes replacement difficult to impossible (well, until the switch to HD, which meant everything had to change..)

 IMHO, the trouble of
 removing the plug and plugging it back in is not 
 worth the cost of a replacement cable.? I
 suspect it has worked fine for 
 several
 years.? If not, look for a better quality cable.
 
 In case the problem is caused by contact oxidation, removing the plug 
 and  re-inserting it several times should wipe the contact area
 and  restore it to normal operation.

The problem with this is, if everyone else is as misguided, then they are 
transmitting with ten watts too. So their signals are 10 to 20+ dB weaker than 
with higher power, hence there are fewer stations to work, ie. less DX.

Furthermore, with more power, faster modes of communicating are possible.  More 
stations can make QSOs in a given time, which can actually *lower* the total QRM 
level.

Of course, all of this is from a DXer's perspective.  If watching paint dry is 
your thing then stick with QRP.

Have you ever listened to the interviews of the Indy car drivers after a
race?  Do they say: "I wish I had a less powerful engine to make it a more
challenging race."?

I'm on the DX end a lot these days, and I always find myself stopping a
pileup to ask if there are any 10 watt or less stations calling.  The
response I get is usually three QRP stations responding (which I eventually
work after 10 minutes of additional instruction to much louder stations)
buried by 100's of QRO stations with massive antenna arrays.

Tough to win!

I will second that.

I built two Weber MTRs and in many ways it was easier than through-hole, except for the size. I used a soldering iron.
?No soldering required? kits are no fun to me. I would never say that I built my KX3 for instance, only assembled it.

Subject: [Elecraft] KPA500 fan shut down problem
Message-ID: <97681697B61A4FFDBFF43857B9A09F26@HPNetbook>

I?m wondering if anyone else has had this problem?  When I shut down the KPA500 from the front panel the cooling fan turns on and instead of shutting down it continues to run until I turn the power off on the rear panel.  When I turn the  back panel power switch on again the fan immediately comes on and never stops until the back panel switch is turned off.  I originally had this problem 3 years ago and Elecraft had me install a SMT bypass capacitor on the back of the front panel board that I thought had taken care of the problem (It did for several years).  I have reloaded firmware, done a full reset, etc. but the problem persists.  The amp work perfectly other than this glitch.  Any help is appreciated.

Thanks, Todd

Not all "serious hams" would agree with you. In my 
first SMT effort I was very careful but lost one 
part. Looked all over for it. Two days later I 
found it in my shoe.

I have paste, hot air gun, hot plate -- all the 
goodies -- but I try to avoid using them, a matter 
of mental stress -- and, to be honest, age. 
Something as complex as a K1 would be a bit much. 
I prefer the pre-mounted SMT component kits, if 
there are to be SMTs.

And, not all hams are able to have a workbench or shack to house the  
needed gear.  Sometimes, things like that intervene.  While it would  
be nice to be able to build, not everyone can, even if they have the  
desire and experience.  Doesn't mean they aren't "serious" about ham

Do not confuse the high quality cables and plugs used in studio patch 
bays with the cheap crap we find in today's consumer market. Cables are 
flimsy, connectors are flimsy and have dissimilar metal issues. The only 
audio connectors I trust are those made by Switchcraft (USA) and Neutrik 
(EU). Years ago, Switchcraft marketed high quality DIN connectors made 
by Preh. I don't know if they still do.

LOL, yes, size is definitely an issue. I use glasses, a magnifying lens and tweezers. You do not have to cut leads that end up everywhere though. It is precise work, no doubt, especially on the ICs. I know in ten or fifteen years I may not be able to see those parts anymore. I like SMT though, didn?t think I would. With good eyes and a steady hand, anyone can do it.

And here's a third.

I built one of Weber's ATS-3B kits and use it on occasion, such as during 
Field Day 2011.
<http://www.genebitsystems.com/david/HamRadio/FieldDay2011/FieldDay2011.htm>   
The demand and popularity of his kits is evident as the last run of MTRs
sold out literally hours after it was released, see  here.
<http://w2mdw.blogspot.com/2013/03/steve-webers-mountain-toper-radio-mtr.html>   
There is definitely a niche for SMD kits requiring more builder expertise
and involvement than simply assembling modules together.

I would love to see an up-to-date SMD transceiver kit with a mix of features
lying somewhere between the MTR and the KX3, perhaps even call it a KX2 as
others have alluded to.  My vision for such a rig would be an integrated
station, multiband (at least 80 through 15) with no band module swapping,
half the volume or less of a KX3, with internal antenna tuner and battery,
and a very simple user interface.  It would be CW, or possibly include
additional modes but only if the associated volume increase is minimal.  I
could go on and on but you get the idea.

The KX3 is an awesome radio and I am definitely not criticizing it.  There
just seems to be a huge void between it and the lower-tier rigs.  And a
solder-required SMD kit is appealing to many builders.

Todd;

You may need to get back to CS about this. When the KPA is powered off from the front panel,it first shuts off the 60V supply, does some other things, then one of the last things done is to turn on the fans. This is an important safety feature to discharge the big power supply capacitors. The fans will run full blast for a short time, slowing to a stop as the capacitors bleed off. Note that even though the 60V source if off, those capacitors will still be charged (and at least some part of the 60V output will remain) until this process completes. 

If your fans keep going, it sounds like something is causing the 60V power supply to stay on. Just to make sure, is this what you are saying?
Did you recently open up the KPA, move cables, or anything like this?

When I shut down the KPA500 from the front panel the cooling fan turns on and instead of shutting down it continues to run until I turn the power off on the rear panel.  When I turn the  back panel power switch on again the fan immediately comes on and never stops until the back panel switch is turned off.  I originally had this problem 3 years ago and Elecraft had me install a SMT bypass capacitor on the back of the front panel board that I thought had taken care of the problem (It did for several years).  I have reloaded firmware, done a full reset, etc. but the problem persists.  The amp work perfectly other than this glitch.  Any help is appreciated.

Some would likely take exception to that strong implication that one is
not a "big boy" (whatever that means) if one rejects significant SMT hand application.  I've been a ham almost 50 years, commercial radiotelegraph licensed until standards dropped 20 years ago, and an electrical engineer
for 40 years...is that "big boy" enough?  Perhaps not...yet I'm not hesitant to state that hand-application of SMT components is a "half-vast" :-)  misapplication of technique to devices designed solely for machine placement.  It should never be required in any step of production of a commercial
product, even for hams.  So, to any enterprise proposing to *sell* something
that requires significant SMT hand-application, I would *not* give such a
product even a moment's consideration.  OTOH, supply the PCBs with SMTs
pre-fixed by machine as designed, and I'll likely be very interested.

Well...there you go again.  I suspect most of us will just *never* qualify
as a N4OI "serious ham", for lack of meeting these canonical and doubtless
universally-recognized requirements for the title. :-)

Phil,

I suspect the cost would be significantly greater than for the assembled 
board version that we have now.
To produce a kit, the parts would have to be pulled and counted, 
capacitors hand marked for values and packaged in some reasonable manner 
- that is a lot of labor cost.  Much greater than loading a reel of SMD 
components into an automated placement process as used in a board 
manufacturing house.

It is no wonder that we only see small projects in SMD format.  The 
Steve Weber transceiver kits are an exception.

73,
Don W3FPR

On assembling versus building...

I think my hobby of woodworking has almost ripped away my soldering iron from my hot little hands.  I still have a solder-kit sitting on my desk ready to be put together (the W1 meter) and it just sits there.  All my spare time this summer is building white oak deck chairs for the back patio.

Aside from that comment, I do enjoy soldering but I am very glad that Elecraft makes the assembly kits available to we the customers.  I like this because:

     --- I personally enjoy the process of putting it together and maybe even more
          then using a soldering iron (I really liked my Erector Set as a kid).

     --- I get enjoyment out of marveling at the great engineering and design that
          goes into the kits.

     --- I learn the inner workings somewhat so that future options are not a scary thing
          to install.

In this, soldering in a kit has no advantages to me as I will never been customizing or changing the workings
of my Elecraft gear.  Even the little electronics diddling that I do at rare times is via a breadboard approach
and again not using a soldering iron.

My two-bits.

73, phil, K7PEH

Thanks for the ideas guys.

I've emailed support at Elecraft to see what their thoughts are.  I did 
some additional testing.

I connected K3-B to my KPA-500/KAT-500 combo and I'm finding that the 
K3-B sees a 1.5:1 swr while driving the KPA-500.  The SWR of the KPA and 
KAT swr meters both measure near 1.0:1.  All other bands show 1.0:1 
while driving the amp.  K3-A sees a 1.0:1 SWR on 40m while driving the 
KPA-500.

Something is up with measuring SWR on 40m with K3-B, even after 
calibrating the wattmeter.

Subject: [Elecraft] K2 tx/rx switching problem - help please ;-)
Message-ID: <mailman.0.1405880463.11565.elecraft@mailman.qth.net>

Hi All,

 

I have a K2/100 feeding a KPA100 in an EC2 case. I have a foot switch and cw
paddle connected to the key socket at the rear of the K2.

 

I have a problem with the tx/rx switching. When on cw the tx / rx switching
works just fine, but when  on SSB and I press the footswitch OR key the
paddle OR the PTT switch on the mic socket ,  the K2 switches into tx mode
OK but when I release Ptt switch (any of the three ) the rig returns to rx
but the received volume is severely attenuated. Only careful listening
confirms that it is actually receiving. 

 

I can resolve the issue by repeatedly pressing the PTT switch (any of them)
many times or (oddly) by pressing certain  buttons on the K2 eg Mode , band,
Pre amp, or even turning the power control up or down so it switches the KPA
in or out . Not all buttons clear the issue but most do.

 

I have no idea where to start looking for  the fault and I would be very
grateful for any suggestions of what this might be. I have a suspicion it
may be an Aux Bus issue.

 

I don't think it is a sticky relay as the eventual return to full receive is
not accompanied  by a relay click and anyway I think the entire tx/rx
switching is solid state.

 

Any help or suggestions please. 

 

Replies direct to me if possible , please.

 

Thanks in advance !

Good Day,
     Another extra inning game put me to sleep in my chair last night.  
Luckily this one did not go 16 innings like the first one did.  
Conditions have been poor lately with a few good openings. The sun's 
flow of ions has slowed to the point where our ionosphere is depleted.  
Hopefully there is enough latent activity that we can hold the nets.  
For the last few weeks check ins have been sparse.  On forty meters 
there has been just one check in each week.  But winter is coming and 
conditions will change; maybe better or maybe not.

Please join us this afternoon and evening.

Have you ever listened to the interviews of the Indy car drivers after a
race?  Do they say: "I wish I had a less powerful engine to make it a more
challenging race."?

I'm on the DX end a lot these days, and I always find myself stopping a
pileup to ask if there are any 10 watt or less stations calling.  The
response I get is usually three QRP stations responding (which I eventually
work after 10 minutes of additional instruction to much louder stations)
buried by 100's of QRO stations with massive antenna arrays.

Tough to win!

Wow has this topic morphed...I was only following it casually, but it 
"was" (I think) about what power level is "safe" to run on the K3 
with "key-down" modes like JT65.  RTTY is pretty hard on the 
transmitter, as well.  FM would be the hardest as  it is usually 
accompanied by marathon talk-a-thons (note most VHF-FM radios are 
equipped with time-out-timers set to a max of 3-minutes).  JT65 runs 
about 50-seconds in Tx and then rests for about 70-seconds in Rx 
(2-minute TX/RX cycle).  The K3/10 seems to be happy at 8w running 
JT65 on 6m (I have not run JT65 on HF).  Psk-31 runs well at 12w with 
my K3/10 with no apparent heating issue.  Note: I have a 300w sspa 
that runs 275w on HF with 12w drive when I need more for SSB.

I suspect all you have switched to talking about normal CW/SSB ham 
radio - they do not compare to JT65, JT9, etc.  These are superior 
"weak-signal" modes designed for when signals are too weak to copy 
using CW.  The software provides about 10-dB better SNR (making the 
10w JT65 signal equivalent to 100w CW).

On HF, SNR requirements are very much lower than the usual RF level 
used by hams.  Evidence:  look at the QRP-SSB check-in's that are 
quite satisfactory on the Sunday Elecraft Net.  I checked in this 
morning with 12w with my K3/10 "barefoot" and was heard on the first 
call by Phil.  Yes, I run an old triband beam at 50-feet which helps.

My s-meter report would be about 2-units higher if I ran 100w, but 
that was not necessary for the communications link.  Working 
contests/DX, is a different "animal" as you are dealing with QRM and 
not specifically weak signals. How many of you are using JT65 for 
contesting or Dx'ing?  You can, you know!  (probably too slow for you)

I just finished operating the Dubus Magazine 2-meter digital EME 
Contest where I ran JT65B with 1000w and four ten-element 
yagis.  Yes, it was weak-signal and I did run QRO.  I have run as 
little as 150w on 2m-eme successfully by using JT65, but it is more 
difficult to make contacts and not particularly a good idea in a 
contest.  Minimum time to complete a valid JT65 eme contact is 
5-minutes if you have a good to great signal.  Running 150w would 
probably extend the time required by a considerable amount - not 
desirable in a contest.

PS, Dr. Schmidt:  I am not picking on you, just happened to decide to 
comment at your post! ;-)
Oh and how many folks drive an indy car to the market?  Different 
needs require different means.

Note: I began 2m digital-eme in 2003 using JT44 precursor to JT65, so 
have a few years experience in its use.

Vic,

Yes, the T/R switching in the K2 is entirely electronic - no relays are 
used.  You may end up discovering an unsoldered connection or a poorly 
soldered one somewhere in the RX chain, but you can make some other 
checks before searching for an elusive problem like that.

Since you do not have the problem in CW mode, that leaves the KSB2 as 
the major suspect - but there can be a few other potential problem 
spots.  I do not believe it is the AUX BUS.

Does the problem occur if you use a SSB filter other than the OP1 
filter?  If so, the most likely problem is that the voltage at KSB2 U1 
pin 21 (the RXS signal) does not always come up to 5 or 6 volts when the 
K2 switches to receive OR a problem with the diode switching of the OP1 
filter on the KSB2 board - check the soldering of those diodes and other 
components adjacent to the filter.

No problem there?  Go on to the next paragraph.

Open the K2/KPA100 and leave the KPA100 connected (put it on a book or a 
box to the right of the K2).
First thing to check is the state of the 8R and 8T voltages during 
transmit and receive.
An easy place to monitor the voltage of 8T is at the anode of D7 and 8R 
at the anode of D6 on the RF board.
Is the 8T voltage very close to zero during receive?  Is the 8R voltage 
close to zero during transmit?
If the 8R voltage does not drop to zero during transmit, it can be due 
to an old KSB2 board which does not have D5 installed - install a 1N4148 
in the path between P1 pin 3 and the collectors of Q2 and Q3 (yes you 
will have to cut the trace).
The other reason that 8R does not drop to zero is a damaged RF board Q23.

That is the best I can offer until I have more detailed information.

Don W3FPR

Vic,

Another thing to check is your coax - a loose coax or one that has a 
failed connection to the shield will behave as you have experienced.  It 
may transmit OK, but is slow returning a good path for receive.
Admittedly, it should fault regardless of CW or SSB, but is worth a look 
in any case.  The best check is to substitute another coax.

To send it to Elecraft requires an RSA number be issued.  The first step 
to have one issued is to contact support at elecraft.com.

I purchased and built a K1 Transceiver with a two-band module for 40 and 20 meters at the end of 2012. ?I immediately fell in love with Elecraft's products, and soon after ordered a KX3. ?I don't do much portable operation, so the K1 has sat idle for about a year and a half. (The KX3 has found a permanent position on my operating desk in front of the Yaesu FT-2000!).

I have taken the K1 to the back yard a few times in the short time I've had it, and I can tell you it does a fantastic job.

Here is the rundown: ?K1 Transceiver with 2-band module, S/N 3198; the backlight kit, the KAT1 Internal ATU, and the Finger Dimple. ?I wisely ordered the pre-wound toroids for the transceiver from Mychael Morohovich, AA3WF(an Elecraft approved vendor), so all the toroids are properly wound and aligned.

I will sell the K1 and include the XIT XTHC40 medium hard photographic equipment carrying case I keep it in for $450.00.

PayPal preferred, but I will accept a check or postal money order. ?Please contact me privately via email to work out the details.

Thank you for the bandwidth.

I find an 8877 provides about 22 dB SNR over ten watts. :-)

I have to agree with Mike, especially with the assertion about SMT 
components being intended for robotic assembly.

Imagine all of the troubleshooting calls and e-mails that Elecraft would 
get if Joe Ham had to populate circuit boards with these miniature 
components.  Too much room for error.

While I'd prefer a through-hole kit where soldering was required 
(although I hate winding toroids!), like the K1 and K2, if the KX3 had 
even one SMT device, I would not have purchased one.

Message-ID: <CAMFZV807HRy7_GrRLkxDH1DaeyY4XTawTDmtu9MuzcuhhTwchw@mail.gmail.com>

Good afternoon,

I finally had some time to sit down with the Fred Cady Manual and the
Elecraft Programmer's guide.

I operate mainly PSK/JT65 and phone and having the ability to quickly
change over to phone if there is rare DX (for instance) would be nice to
have.  So I broke out the programmers guide and worked up the following:

PF1 switches the radio to Data-A, Filter 4k, Mic gain to 20, power change
15W, etc.

The PF1 string is as follows:  MG020;BW04000;AG005;MD6;DT0;PC015

PF2 switches to SSB:  MG020;BW02100;MD2;PC100

(Yes, I do own a KXPA100)

I have sucessfully assigned the macros to each PF.  The problem is that I
push and hold either PF on the KX3 and it seems to execute part of the
macro but not all.  To get it to fully complete, I have to press the same
PF key again and then all settings are correct.  So my question is, is this
a bug, feature, or user error?

Thanks and 73

I'm not a QRP fan for DX.  However, one can definitely copy a weaker 
signal with JT65.  No matter how much power you have, you can't work 
them if you can't copy them.  It seems like the magic combo is 1500 W 
and JT65 on both ends.  I think guys are resorting to this on 160M to 
try and squeeze out a new one or two.

The five minutes or so per QSO is a bummer though.

Hi,
The BW commands are incorrect.  They should be in 10Hz increments.
Thus for SSB you would want BW0210; not BW02100;
Could be the reason.

Message-ID: <e9b9.412e58f6.40fda858@aol.com>

I used my KX3/KXPA100 in the NAQP RTTY contest this weekend. The KX3 with  
added-on heat sink worked very well; however, the KXPA100 repeatedly faulted 
 with HI TEMPERATURE indicated on the KX3 at full output after prolonged  
operating (lots of CQ'ing with short pause intervals). PA.X temp indicated at 
 failure was around 60C...as it should. Shack temperature was around 70 
degrees  F
Yes, I know all about digital modes and full power stressing amplifiers,  
etc. What I want to know is how to mitigate this interruption yet run full  
output. To that end, I have a couple ideas: what if I mounted the amp 
vertically  so the heatsink fins "drew" cooler air through themselves via 
convection?  Secondly, would a couple muffin fans mounted atop the cooling fins do 
the job? 
The net of this is that I'd like to enjoy the full benefit of having a  
high-quality 100-Watt amplifier, regardless of mode or key-down time.

I have for sale a current production Vibroplex Blue Racer bug - it's 
just over a year old and was purchased at Dayton last year for almost 
$230.  It has the blue base and jeweled pivot bearings.  I'll include an 
extra weight to help slow it down below 20 wpm if desired.

It has become surplus to my needs here and I'm willing to let it go for 
$175 plus USPS medium flat rate box shipping which is currently $12.35 
anywhere in the U.S.

USPS Money Order or PayPal accepted.

High resolution pictures are available by email on request but this key 
is a 9 out of 10 with a minor scratch on the label (there when I got 
it).  Serial number is 400,020.

Anyone interested, please email me off list and first email (by 
date/time sent) gets right of first refusal.

While I understand this mindset; I for one, am grateful that there are
SMT-based kits available. I enjoy building both thru-hole and SMT based
projects. In many cases, thru hole equivalents are not available for some
components. I have built many all-SMT projects, notably those offered by
KD1JV,ad formerly NJQRP (now Midnight Design Solutions), among others. 

No, they are not for everyone. But- I am glad they are offered for those of
us who can and do enjoy building them. It is not nearly as difficult as some
seem to believe it to be. Different techniques are required, that's all. In
many cases, a much more compact package, or an otherwise impossible project
is the result.

Why not run it at 50 watts and give up the 3db.? Probably will not make a difference in number of contacts and your thermal problem should go away.? Also what is SWR
?

Support your local "maker space", they will likely have the gear and knowledge to do SMT? and probably a bunch of young guys that have never seen HAM before or know the potential.

More power to you and others who have the patience, equipment and 
eyesight/hand coordination to work with SMT devices, Bruce.
I think what many of us are saying, is that type of construction is not 
for everyone.

I have a nice Weller soldering station and a variety of tips for it, as 
well as enough 63/37 solder to last a lifetime.
Somehow it fell into my tool pouch from time to time, when I was in the 
Air Force working on air traffic control radar systems.  :-)
I'd rather spend my money on other items for the shack, than for the 
tools necessary to do SMT work.

Maybe if there hadn't been the inference that we weren't "big boys" if 
we didn't build kits with SMT devices, this thread may have passed, 
unnoticed.

I have had this problem for a long time with the 
KX3 and ultimately figured out that the solution 
is exactly what Dan had stated.  When using the 
SignalLink USB only use VOX (on the KX3), or on 
the K3 use the back panel PTT and do not use the 
CAT for PTT.  Without this the combination 
consistently creates exactly the race condition 
that puts the K3/KX3 in an indeterminate state 
requiring the XMIT panel button to clear.  I 
think the problem is that the delay in the 
SignalLink release of the PTT line.  That is the 
CAT control tries to open PTT while the 
SignalLink USB is still grounding PTT so the 
radio does not know what state it is in.

I use this system and it works fine as long as I 
do not try CAT control for PTT.

Thanks,

My first experience with SMT was building a softrock multiband
receiver kit. It is a hybrid through hole/SMT kit, with few different
types of SMT devices. I really enjoyed building it, and learned a lot
from it, and would recommend it to anyone wanting to dip their toe in
the water, so to speak.

ObElecraftContent:
Elecraft does have a kit where you have to solder an SMT device -- the
wideband noise generator. I got to practice twice with that one: once
when I first build it, and then again after I have a little accident
with a transmitter :-)  I was going to try to remove the damaged
component with a hot air rework station that I picked up recently, but
with the plastic battery holder etc. nearby, thought better of it and
just snipped off the fried component with my side cutters, with no
dramas.

Oh yes, that!  I didn't think of it as SMT because 
it has four leads.  Took me a while to figure out 
how to orient it, though. I sneezed and almost 
lost that critter.

And I have two spares -- so mine is likely to last 
forever.

I used my KX3/KXPA100 in the NAQP RTTY contest this weekend. The KX3 with
added-on heat sink worked very well; however, the KXPA100 repeatedly faulted
  with HI TEMPERATURE indicated on the KX3 at full output after prolonged
operating (lots of CQ'ing with short pause intervals). PA.X temp indicated at
  failure was around 60C...as it should. Shack temperature was around 70
degrees  F
Yes, I know all about digital modes and full power stressing amplifiers,
etc. What I want to know is how to mitigate this interruption yet run full
output. To that end, I have a couple ideas: what if I mounted the amp
vertically  so the heatsink fins "drew" cooler air through themselves via
convection?  Secondly, would a couple muffin fans mounted atop the 
cooling fins do
the job?
The net of this is that I'd like to enjoy the full benefit of having a
high-quality 100-Watt amplifier, regardless of mode or key-down time.

Bert N4CW/K1IMI
---------------------
Bert,

Using radial "muffin' fans to cool amps running digital modes is 
standard practise to save the amps from heat stress failures.  Just 
get enough to cover the surface area of the heat sink fins and you 
should find that it has solved the issue for the KXPA100.  Fin 
orientation is not important in that case.  Note the 100w amp in the 
K3 has two fans.

I run two fans on my 170w 2m linear and all my transverters have fans 
on the heat sinks.  I simply laid a 4-inch fan on top of my 150w 6m 
amp to keep it cool when running JT65.  I'm thinking of adding a fan 
on my 15w 900-MHz FM transceiver for a little insurance.

Note: I added a heat sink to my KX3.

There are excellent reasons for QRP.

As chance would have it, I spent an hour or two today at the NCDXC club 
picnic chatting with AF6RT, who spent Friday and Saturday lighting up a 
very rare grid on 6M (CM79, I think) that involves lots of hiking over 
rough terrain carrying your gear, then making additional round trips to 
get more gear. The hike is on the order of 2-3 hours one way. He's not a 
CW op, and he said he ran down his batteries calling CQ.

The objective is to pass out this very rare grid (99.99% is water) to 
those pursuing the Fred Fish Award to work all grids in the US.

One of my suggestions was to encourage him to use JT9 (24dB of noise 
rejection referenced to a 2.8 kHz bandwidth) and a strategy where he 
announces (on the Ping Jockey JT65 chat) a JT9 window where the 
deserving will call him, and he will respond only to those who he hears. 
W7GJ/KH8 is successfully using this strategy on a moon-bounce expedition 
to American Samoa. I also suggested that he try to use the KX3 barefooot 
when the indicated S/N is better than about -10 dB, and use only enough 
amp to make the Q. The objective, of course, is to minimize current 
drain, and thus maximize operating time.

The WSJT-X software has a multii-decoder, and gives a readout of the S/N 
for each signal it copies. I also encouraged him to replace his K3 with 
a KX3 and KXPA100, because of the KX3's greatly reduced current drain on 
RX (250 mA as opposed to about 1A for a K3).

I'm looking at Li-Ion battery packs that we might pitch in and buy for 
him, and that raises a few questions for Wayne. I can find nice Li-Ion 
packs with 3 cells (11.1V nominal) or 4 cells (14.8V nominal).

1) Can the KXPA100 and KX3 tolerate the higher voltages of a fully 
charged 14.8V battery pack? (In the range of 16V).

2) Do the KX3 or KX3 pull proportionally less current for the same power 
output from a 4-cell pack as compared to a 3-cell pack?

3) I'm seeing some 20Ah packs rated for a max of 10A and 14A load 
current, with active protection to limit the current to those levels. 
How would the KXPA100 react to that, if he wanted to run 40-50W?

4) Where can we access a graph of KXPA100 load current vs. 6M power out, 
not considering tolerances from one piece to another?

5) Am I correct that a KX3 does not benefit from an outboard preamp in 
this application?  That is, a very quiet QTH, he's current starved, the 
guys who want to work him have power and big antennas (but probably more 
RX noise), and he's got to fight for every dB.

Weight for a K3 as compared to a KX3 + KXPA100 is about equal, 
especially when interconnect cables are taken into account. The 
advantage is current drain, and is a big deal if 90% of your time is RX.

He's already carrying a very nice M-Squared antenna and mast to hold it, 
and LMR-400 to feed it.

Those reading the mail should appreciate this as a very practical 
engineering problem. :)

We don't need fast response on this -- thanks to work commitments, his 
next window of opportunity is Memorial Day 2015. :)

Subject: [Elecraft] [K3] UPS for K3
Message-ID: <005f01cfa4d4$7b9be4f0$72d3aed0$@net>

Is it overkill to power my Astron RS-35 power supply that runs my K3 from a
UPS?  I am looking at a CyberPower CST1300AL from Costco
(http://tinyurl.com/pajlsav) .  It produces a "modified sine wave" when the
primary power has been lost, which is true of most UPS models.

I'm usually home so the plan is to turn the K3 off with its power switch in
the event of a power failure.

Looking at
http://www.cyberpowersystems.com/support/faqs/topologysinewave.html my
conclusion is that type of UPS is adequate for an Astron supply powering the
K3, a computer, and accessories, but I'm no engineer.

In my opinion, yes- it's overkill. I personally would probably use the
Astron to float a deep cycle or SLA battery on it's output. You might also
want to investigate adding a PWRgate or similar Schottky diode matrix to the
mix. This would provide not only the protection against abrupt power failure
that you seem to seek, but also provide some additional operating time in
the event of power fail. Those UPS units are designed to run for only a
handful of minutes, while a computer system shuts down.

Here is a link to the PWRgate that I believe Bruce is referring to. This item is a compact, relatively low cost, well regarded solution that would be appropriate for use in the scheme Bruce has suggested. A yellow or blue top Optima, or other good AGM battery, along with a PWRgate, wouldn't cost too much more than the UPS being considered, but would be much more useful & versatile.

Wow -- I kind of touched a nerve with the "big boy" reference!  I recall this
term was used by Dave Benson in some of his SWL kit documentation.  It
merely referred the reader to a stripped-down section of the instructions if
one wanted to bypass the lengthy, step-by-step narrative...  My point is
that manufacturers, such as the premier innovator, Elecraft, should not be
constrained in their product designs by offering only through-hole or
solder-only kits. Why, even TenTec has leap-frogged the industry in this
area with their open-source, Rebel QRP platforms! 

I apologize for the poor use of words.  As a relative newcomer to ham radio,
it was not my intention to denigrate anyone on this reflector - especially
those who have vastly superior technical knowledge and capabilities.

I don't think it's a matter of technique, Bob. I 
have all the right equipment (the special 
tweezers, solder paste - in the fridge, a hot 
plate, a heat gun). And I will do small, simple 
boards -- which even a 4-band K1 would not be.

My problem is knowing that an ill timed sneeze can 
cause a serious problem - and it has. Plus as I 
age my hands get a bit shaky, another problem. So 
I avoid SMT whenever possible, to the point of 
paying someone else to do it as in a recent project.

Interesting!  I was thinking along the same lines about a UPS for the 
shack, but for a different reason.
Aren't today's solid-state radios susceptible to damage from transients, 
much like our computers are?

I would not turn on a computer that was not first connected to a quality 
UPS with surge protection.
So, maybe not so much for backup, as most UPS are designed to continue 
to supply power to the computer and peripherals long enough to effect an 
orderly  shutdown.
We don't suffer from protracted power outages here, but rather from sags 
in the line voltage.  This is especially true in the summer, when 
temperatures reach 100F and higher.

But, what about surge suppression for our shack equipment?  Or is this a 
silly question?  Are we more susceptible to damage from lightening than 
from dirty power?

No.  The products are not guaranteed to FAIL if you apply 16 V, but they 
are not designed to operate from 16 V, either.

The KX3 low voltage supplies are primarily switching supplies, so 
current drain at a higher input voltage will be less than the current 
drain at low supply voltage.  The PA (KX3 or KXPA100) operates directly 
off the supply power and current is proportional to power level and 
drive, but not supply voltage.

I don't think anyone mentioned this, but the inverter part of a UPS is a
switching power supply. Why add to the potential noise cloud around the
station? I have noticed lots of noise pollution from my various computer
UPSs. The solution of floating a battery across the output of the
regular 12v supply seems simpler and quieter to me.

Good question, Jim.   I believe you are correct.

You might investigate power conditioning equipment for protection from 
both surge and sag and transients, and they appear to provide add some 
degree of regulation.   Furhman is a respected power conditioning brand 
for gear that is used in recording studios and with rock bands and 
doubtless there are others.

Simple SMD kits are fine because the success rate can be high and the investment risk on the part of both the customer and the manufacturer is low. We may offer such kits in the future, though we don't have any present plans for these.

The percentage of builders who could complete a complex SMD kit, or have the skill and test gear to troubleshoot them, is small. Kitting and documentation alone would be a huge investment for us, not to mention customer support. Many such kits would never be finished, or repaired, or would have mysterious unresolved issues. Perceived quality would suffer and frustration levels would go way up. 

One thing Elecraft is known for is packing a lot of functionality into a small space. This requires the use of very fine-pitch TQFP IC packages as well as 0603 passives (even 0402 in a few cases). To make SMD kits viable at all we'd have to use much larger-pitch parts. This would force products to be larger, heavier, and more expensive.

Even though a small percentage of customers would be willing and able, this simply isn't an economically viable direction for us.

Hi all,

as I started that idea with the SMT components, I will try to moderate a
little bit.
I am over sixty and so I know the problems with needs of special glasses
to handle the
SMT components down at 603 or 402 ( 1  x 0.5mm).

So my idea is, not designing without SMT, but for those who like it,
provide kits with
premounted SMT , so that these users may build their kit without the
needToday  to handle and
solder SMT "sand".

Today in some cases the "wanted" parts are no longer available as THT.
In the future this will be
the case for more and more parts. The most evil thing is, that some very
interesting part are even
today only available as BGA SMT which needs the handling by special
tools or machine just
for the placement ?!

So let's have fun and let's not forget to prepare a way for those which
can not or are unwilling to
solder SMT

Thanks to all who made suggestions. I will be trying one or two fans atop  
the heat sink and see how that works out in the next RTTY contest foray.
While looking into possibilities, I checked out the web site where I got my 
 "add-on" KX3 heat sink (https://proaudioeng.com/products/) and found they 
had  added a new product, a power supply specifically for the KX3. Specs 
look  promising. [I don't have a vested interest in the company, just pleased 
with the  heat sink.]
Again, this reflector is a great source for ideas about great  products!

Yes, I know all about digital modes and full power stressing amplifiers,  
etc. What I want to know is how to mitigate this interruption yet run full

vertically so the heatsink fins "drew" cooler air through themselves via  
convection? Secondly, would a couple muffin fans mounted atop the cooling fins  do 
the job? 
The net of this is that I'd like to enjoy the full benefit of having a  
high-quality 100-Watt amplifier, regardless of mode or key-down time.

Make sure you put the fans the right way around, ie. sucking up the hot air and blowing it away from the heat sink :-)

When I was using my K2/100 on RTTY, I stuck a muffin fan over the hottest part of the heatsink with a little square of sticky back velcro.  Could run 100 watts just fine.  Fan blew down.

Thanks, Lyle. The additional question I was asking here is if the 
KXPA100 pull proportionally less current from a 14.8V supply to achieve 
the same output power than from an 11.1V supply?  (The difference is one 
less cell in the Li-Ion pack.) The calculation I'm getting at here is 
for a given pack weight, do 11.1V or 14.8V packs give me the most power 
out per pound?

I think some where my original question go lost.  Can the K3 operate key 
down at 100W's.
I did get an answer, yes - 120w for 24hr's...  So the answer is yes.

I complicated things by adding JT65 and that I operate at 0.5 to 2 watts 
with my KX3, but up to 20w with an IC-706.  Yes, if I am -25db at 0.5 
watts, I can/should up the power so the "guy" at the other end can hear 
me better.  Yes, it IS weak signal not low power...

The NAQP contest this past weekend was fun (I used the O2).
It has been a few years since I got the chance to operate a digital mode 
contest.
The great receiver in the O2 did fine and is why I would only think of 
replacing the O2 with a K3.

everyone have a great day!

Well, yes...  {less powerful engine} After the late 60's the rules were 
changed to require all cars to operate under the same limits. NO more 
turbine cars... (for a $6 ball bearing...)

I've been using that circuit for years, the double diode Schottky circuit, because the company I worked for at the time used that same circuit to keep the backup SLA batteries charged in their repeaters. It' a very simple circuit and you always have a charged battery when power fails. I believe this is the best way to go as you always have the DC batteries on trickle charge while the AC power supply is running the rig and supplying the trickling. So all my main radios are run from their own 100AH (sealed lead acid) batteries with a PowerGate type circuit keeping them charged. We don't have a lot of power failure where we live in AZ but during the monsoon rains we can get some power bumps. I like using this type of circuit because it isolates the radios from any of the power bumps and brownouts we sometimes get. Essentially all my radios are running off batteries. The changeover from AC to Battery is instantaneous with no hiccups no matter how many times the power bumps. I still use UPSs for my computers because their primary power source is AC.

I have used this simple circuit to power scanners and 2m radios during power outages. I used some smaller rated diodes then the ones called out because I had them. (15 and 20 amp) I had some 7AH batteries out of my UPSs and a 58 AH for my 2m radio kicking around. As long as the current draw does not exceed the rating of the diodes you're OK. I even heard of one person who was going to use diodes out of an alternator. Don't know if he did. I build my smaller circuits on a screw type terminal strip with a clip on heat sink on the diode and attach the strip right to the top of the battery with double stick tape. My scanner is run off a 12v wall wart and a 7AH SLA instead of a PS and works just fine.

Because of the drop through the diodes, you may have to turn up your voltage from the PS to compensate.

Been running several these circuits for several years with no mishaps. (always fuse power circuits)

Subject: [Elecraft] KX3 sidetone bug when recording memories
Message-ID: <53CE04B3.7040702@ladegast.info>

Hello list,

I just noted another misbehaviour on the KX3 (MCU firmware 1.94 and 2.12):

When disabling VOX in CW mode and recording a text into one of the 
memories 1-6 and using the ending phrase <IM> (..--) at the end of the 
text the CW sidetone stays on until I press another button. I usually 
tap MSG again and the sidetone stops.

Seems like the confirmation tone of the <IM> ending starts but does not 
stop until another sound is played...for example a key press.

I noticed when I set up CW memories testing the fast play mode in the 
contest and programming the memories in the field. I usually use the KX3 
utility for that but in the contest you want your transmission end as 
quick as possible (using <IM>).

This behaviour only happens while recording memories and not while playing.

Regards!

Sven, DJ2AT

There will always be disagreement on this but I vote for blow when 
external forced cooling.  The air can be directed exactly to where it is 
needed, not sucked from all over the place.

I ran my K2 overnight for days at 50W doing some Grey-line propagation 
tests.  Small external fan tilted at 45 degrees and blowing down onto 
the heat sink in the area where the transistors were bolted.  The little 
screamer on the back of the KPA100 never activated.

The situation with the K3 is different, the PA heat sink is buried in 
the box and the heat has to be sucked out otherwise all you would have 
is a fan oven.

Regards,

Mike VP8NO

So noted, Sven. Thanks.

There's no need to disable VOX when recording CW messages, by the way. In record mode, transmit is disabled. The usual reason for disabling VOX is to do code practice, and in this case I'd avoid practicing "..--" (IM).

Buddipole battery and charger for sale.  Will run a 100 watt radio for a period and a KX3 all day if not days.  The battery and charger were purchased in March 2013 and used about 3 times with the same amount of charges so virtually brand new.  I had it for my KX3 which I have just sold.  The batter a 4S2P retails for $165 and the Multi 4 charger sells for $79 and this does not include shipping.  I will sell both of these for $150 and you choose and pay shipping.  If interested contact off list.  73?s

This looks like a a relatively inexpensive solution to the temp controlled
fan idea.  They seem to have a reputation for being quiet and reliable.

Salvage a 12 volt muffin fan from a defunct computer and put a resistor 
in series with it to slow it down.  Almost whisper quiet, but it can 
substantially increase the air flow over the heatsink and keep it cool.
Cost, almost nothing.  But put a shield over it to keep fingers out of 
the blades.

Elecraft Reflector participants:
If any of y?all use the N8LP tuning relay w/ your K3 and KPA500, I appreciate your help.
My kit went together smoothly and all ohm meter checks A-OK. When I plug the relay into the SteppIR control box the green light comes on.
I have RCA phono plug cable running from the PTT connection on the relay to the PTT In connector on K3 and another from the PA Key on Amp to the LOOP plug on Relay box.
When I key PTT while SteppIR is tuning, KPA500 does not switch to standby as I believe it should.
Obviously I?m doing something wrong.  I even tried the Key Out connection on the K3 but that didn?t work either.
Any thoughts would be appreciated!

Cary,

I think it will work as you want if you use the small interrupter between
the end of the cable from the K3 where it attaches to the KPA500.

I did that on two of my radios, and built a simple clamp on bracket to 
mount them without modifying the original heat sink fins. Cost of my 
project was approx.  $7 for the fan, and $1.5 for some aluminum stock.

I was particular careful to select fans with clearly stated noise 
figures.  Not all vendors publish the noise figures, but those with less 
than 20 dBA are fairly quiet, and, as Don says, if you slow them down a 
bit, they will move a lot of air over time, and you will never hear 
them.  I can provide photos if anyone is interested in how I mounted mine.

Salvage a 12v muffin fan, and run it off of a 7 volt wall-wart.

Re: blowing air vs drawing air, the object is to increase air flow 
over the heat sink (or tube if no heat sink).  If one does not have a 
plenum directing air over the entire heat sink surface, my bet is 
with blowing.  Drawing air is effective if there is a plenum 
confining the air flow over the heat sink surface.

I you are cooling a tube with fins like some of the 3CX or 4CX types 
then you need the extra force of a blower due to the high air 
resistance (back pressure) thru the fins.  Example a 8877 
(3CX1500A).  I have both a blower and 7-inch radial exhaust fan on 
that amp.  Exhaust fan lowers back pressure that the blower works into.

All my other amps are currently configured with fans that blow down 
onto the heat sink.  I will be installing five fans on a 6m Harris TV 
amplifier (1100w with 16 transistors) that draws air.  That is needed 
as air is drawn thru several holes from the input side of the amp for 
cooling the input components by pulling air into the output side.

Mine was a brushless DC fsn from an old computer.  Quiet running on 12V.  One anomally ... on 15 (only), with beam pointed over shack & 1KW, transmitting slowed it down.  Any other direction was fine

By using the interrupter you will have to key the amplifier with the connection you now have through the N8LP relay (I have one too, but I use it to prevent my 87A, my second amplifier, from transmitting when the antenna is tuning.)

When you interrupt the amplifier key line, the amplifier doesn't visibly
switch from operate to standby. The amp doesn't provide gain unless the
amplifier is in Operate AND the key line is pulled low.

One & only price drop on the Vibroplex Blue Racer bug I listed several 
days ago - it's just over a year old and was purchased at Dayton last 
year for almost $230.  It has the blue base and jeweled pivot bearings.  
I'll include an extra weight to help slow it down below 20 wpm if 
desired.

It has become surplus to my needs here and I'm willing to let it go for 
$170 shipped anywhere in the U.S. lower 48.

USPS Money Order or PayPal accepted.

High resolution pictures are available by email on request but this key 
is a 9 out of 10 with a minor scratch on the label (there when I got 
it).  Serial number is 400,020.

Anyone interested, please email me off list and first email (by 
date/time sent) gets right of first refusal.

Hi Cary,

Be careful. Until you get this figured out you can damage your antenna by
pumping high power into it during tuning. I suggest that you switch to a
dummy load while you are experimenting.

You said you have the phono cable running from the relay to the PTT In
connector on the K3. *This is NOT correct.* You want to run the cable from
the KEY OUT connector on the K3 to the N8LP relay. 

Next you will have to use the key interruptor on the 15 pin cable as others
have advised.

Finally the KPA500 will not go into Standby. It will stay in Operate but it
will just sit there. It won't operate because there is no permissive signal.

And one last thought. Make sure you have adjusted the pot on the N8LP relay
such that the red LED lights when the SteppIR is tuning.

73,
Mike K2MK

Oh well, all good things eventually end.  Kit building in the conventional 
sense is probably a declining interest anyway. Having built both thru-hole 
and SMT radios (ATS-3B), probably enjoy building about as much as operating.

Am thankful to have built a K1-4 (40/30/20/15) several years ago, also 
two-band boards for 80/17 and 12/10.
People who like to build ought to get a K1-2, K2, or KX1 before they all 
disappear due to parts availability issues.

Have never owned a KX1, but for me the K1 is pretty much the ultimate QRP 
radio.  90% of my operation is on 20M,  remainder mostly 40M, with solar 
cycle 15M has been fun too but in another two years that will be over.  30M 
has been used maybe twice.  A 2-band radio would certainly fill my needs. 
Changing band modules is a special pain for me because installed the onboard 
tuner (which is rarely used) into my K1 .  The extra boards have spent most 
of their lives in the desk drawer.

I would think a K1-2 for 40 (or 30) and 20 would still be a very good choice 
for anyone wanting a good performing full-featured QRP radio for home and/or 
portable.

I would like to see Elecraft take either the k2 or kx3 and turn it into 
a backpack unit.

case and all .... we need more lightweight field pack style radio.

I am currently designing a case to move my kx3 to with space for a battery.

the only issue I have thus far is due to the cables and the output from 
the bard having to add in right angle plugs and find a way to secure 
them when in the field.

I am keeping the kx3 in its case this is a drop down in case. that has 
the antenna mount on it and thus forth.

also is there a generic mic that would work withthe kx3 just for keying. 
I dont need the up and down right now...
?

Curt,

All you say rings true. And this is an especially 
important point:

/Changing band modules is a special pain for me 
because installed the onboard tuner (which is 
rarely used) into my K//1/

The band module resides under the ATU board making 
such changes something not done without some 
strong motive. If I had the original two-band K1, 
vs. having the 40/30/20/15 model you have, it 
would satisfy 95% of my operating needs.

Tom/N0SS described 14 years ago a simple technique that
makes a filter board change when the KAT1 is installed
much easier.  He cut two segments from a thin rubber band
and placed them inside the spacers that separate the KAT1
and KFL1.  He threaded the screw coming out below the KAT1
PCB into each spacer with rubber strip in it.  That keeps
the otherwise loose spacers in place on the screw threads
as the screws are turned during KAT1 removal/replacement
for subsequent KFL1 swaps.

The K1 MCU remembers the frequency display calibration for
each band that was set by OFS, using a new KFL1 requires only
loosening the two KAT1 PCB screws, removing the KAT1 (the
KAT1-KFL1 spacers will now remain on the screw threads as the
KAT1 is pulled off), swapping the KFL1, replacing the KAT1,
installing the K1 top cover, and assigning b1 and b2 to the
new bands.

OK...so it's *still* a bit of a pain.  But not having to mess
with those two PCB spacers below the KAT1 is *major* improvement!

I am aware of the "rubber band trick", but I find no difficulty at all 
in plugging the KAT1 even with loose standoffs.
First place the standoffs so they are close to the holes in the board.
Next (and most important) put the long screws through the KAT1 board - 
hold them down with your fingers or thumbs.
Now eyeball the top of the standoffs with the end of the screws and 
insert the screws a bit into the standoffs.
Since the screws contact the standoffs before the connector pins come 
close to their mates, you can now align the connectors and push them home.
Wiggle the screws a little bit to get them to drop into the holes on the 
KFL1 board and tighten them - job done.

Dick, Jim, & Pete (W4WWQ):	
    Thanks for your help.  N8LP Tuning Relay now working as advertised.
The ?Interrupter? was key to getting it to work and once, with the help of Dick & Pete, I figured the phono plug on the K3 belonged on the Key Out jack and not the PTT jack, 
it works perfectly.  As Dick explained, the KPA500 will not switch from Operate to Standby but there is no power output and no LED?s are lighting 
up while the SteppIR is tuning - this is one slick little box!
     Again, thanks for your help!

It has pin 10 removed, which I think/believe is the PTT for the KPA500.  By using the interrupter you will have to key the amplifier with the connection you now have through the N8LP relay (I have one too, but I use it to prevent my 87A, my second amplifier, from transmitting when the antenna is tuning.)

Richard,

To my mind, "keying" is for CW, and a microphone is for voice modes.
So what do you want?  A microphone to produce CW with the KX3 (paddles 
are easier to implement), or a microphone with PTT?  If you want a 
microphone, look into the MH3, it is designed for the purpose.

Certainly other microphones can be made to work, but you will likely 
have to build an adapter.

Below is the actual data and link to the public source of Rick's comment
about rigs used in WRTC.  

73,  Bill  W4ZV

P.S.  In case others missed it there was a major firmware update (MCU 4.86
DSP 2.83) on June 10.  For some reason there was no announcement about it
(see http://www.elecraft.com/K3/k3_software.htm )

WRTC data:

http://mailman.qth.net/pipermail/aocc/2014-July/016712.html

Andy N2NT is still collecting data, but his preliminary release showed the  
following breakdown of radios used at WRTC2014 for 91 radios he compiled.  
I'll show the final when he releases it, maybe later this week.
 
Not surprising figures, as the K3 has a lot of features in a small  
package. Great for worldwide travel. 
 
It should be noted that at least 2 of the IC7600's were loaners from  
sponsor Icom. One pair went to the YL Team of DL1QQ/DL8DYL, who finished
well,  
21st. 
 
More  when I know more.

That's more lopsided (2/3 K3's) than the first WRTC after the K3 came
out (1/2 K3's).

It appears the official report of transceivers and software is here:
     http://www.wrtc2014.org/radios-and-software-used/

The K3 was used by more than four times as many competitors than rigs
from any other manufacturer (Elecraft: 75, Yaesu: 16, Icom: 15,
Kenwood: 8, Ten-Tec: 2).  Interestingly, 41 of the 59 teams (nearly
70%) used a K3.

What size of a generator are you going to use? Also what kind of loads are
you going to be running?
I have experience with all different types, styles, and sizes of generators
because of off grid living. Although mine are now used to only charge the
battery bank in multiple days of bad weather. I have had the big propane
ones that run the whole house.

We also have a Generac generator, and ATS.  I believe it's about 20kW, the 
largest they sell that is NOT water cooled.  I didn't want a car engine...

Our house has two 200A panels inside, and being in South Carolina (hot, 
muggy), we have three air conditioning units, including  mini-split for the 
ham shack, plus all electric kitchen (induction cooktop), and other 
high-current things.  I tried several electricians, all of whom wanted to 
install 30+kW, water-cooled generators, which I could not afford.

We finally found an electrician (as part of a kitchen remodel) that was 
smarter than the average one, and he was familiar with the Generac Nexus 
(sp) line of "Smart Switches".  These are add-ons to the ATS that manage 
generator loading by cutting back heavy loads if the generator gets bogged 
down.  They add a switch to each identified load, and the ATS controls how 
those switches get managed.

We've had the generator run a few times, and I've seen the ATS cutting back 
the load at least once.  I'm usually home during outages, so I can manually 
trip breakers to manage the load myself, but it's nice to see that the 
system works even if we aren't home.

So far, I've been really happy with this setup.

Hi John

The easy part is the size and if it produces power.  The hard part is the
RFI noise, so, somehow, you need to figure out a way to actually test this
in the field (no pun intended) so you can actually hear if there is any RFI
issues.

I would look for similar installations or reference customers from the
vendor.

Your electrician may or may not have knowledge of dealing with radio
interference.   Ask the hard questions so that you get a good answer and
make sure you also write it into the purchase agreement.  If you don't then
the vendor may walk away since RFI is very hard to measure for most other
than those on this list.

Good luck!

The house that my girlfriend and I are currently renting has a 14KW Generac
Guardian Series standby generator.  I need to go pull the battery out and
charge it, I suspect that the battery charging circuit isn't working right
because of a bad onboard control panel. Ours powers everything except the
room where the shack is, the washer, dryer and stove. As I've never had the
generator fire up while I've had an HF radio, I have no clue what kind of
hash or other RFI will become audible when it's running.

As we live in the country, we keep our generator in manual mode and if we
decide we need it, we will fire it up. We pay for our propane as we use it,
so we'll decide if we want to incur the expense.

John,
For a number of years I have had a 16KW Generac Quite Source. Compared to my
next door neighbor's 7.5KW B&S, the Generac is very quiet.
Power here in upstate NY seems to go out several times a year and sometimes
for multiple days.
Thank goodness I am on natural gas for the house.
Also, the battery is continuously trickle charged. Plus the generator runs
at half-speed for around 15 minutes once a week as a test. But the generator
doesn't switch over power during this test. 
My 12V supplies or any other household devices do not have any issues with
the waveform coming out of the generator. Neither does my Acom 2000A. I have
not tried yet my KPA500 under generator power. I have to remember to try
that. The only issue seems to be my Geochron. It loses some time on extended
generator periods. 
Once a year I use a Generac kit to replace the air filter and spark plugs.
They are cheap online. I check oil (synthetic) every couple of months.

I have detected no noise from the generator while operating.
The only thing I had to do was change the setting on my old UPS (>10 years)
units so that they were less sensitive to the waveform from the generator.
My newer UPS units did not show this problem. By the way the waveform looks
a little weird on the scope. 

At the time I bought the generator 16KW was the biggest Quite Source. If I
was buying today I would get a larger quiet source so that all I would have
is a transfer switch between the meter and the 200A main Breaker box. With
the 16KW I had to add a separate switch over breaker box. 
The only things not on the generator breaker box are the second air handler,
ovens and clothes dryer. So, not much of a compromise when on generator
power.

Thinking of adding a battery and charger setup so that when we get a power
glitch the K3's and other 12V devices stay on. Computers and their
peripheral devise are on UPS.

I am sure besides Generac there are other good choices in whole house
generators.

N2TK, Tony

We are considering the installation of a generator here for times when, for
one reason or another, commercial power is unavailable.Our electrician has
recommended a Generac generator.

I would welcome comments from this august and knowledgeable group about
these generators regarding reliability and RFI emissions or, preferably the

Jim,

As with nearly all transmitters, it is a matter of heat.  If you have 
adequate cooling on the left side of the K3, then the internal 
transverter will be capable of a very high duty cycle. If it is blocked 
and in a warm room, then the duty cycle will be significantly lower.

You might want to monitor the side panel temperature and run the unit 
into a dummy load and find out the heat profile for the duty cycle you 
expect to run in the ambient environment of your particular station.  
Vary the power output and/or cooling (a fan, for example) and see how 
that affects it.

Hi Jim,
 
I have used my K3+K144XV extensively on a 2 m Meteor Scatter expedition last year. Besides high ambient temperature during the expedition also the K144XV develops heat quite quickly. It does not take longer than 5-6 WSJT transmit cycles for it to get warm enough it starts reducing output power. The longer it runs, the worse the power reduction (my one started at 9 watts out and settled at about 5.5 watts after half an hour running FSK441). What helps a bit is a fan oriented on the left side of the radio as the K144XV uses the side panel for "cooling". Even better is not to run the transverter at full power out. So as you are just starting searching for an amp I'd suggest to look for one that just needs 5 watts input and drive the K144XV at that level. Takes away a lot of stress from the finals, too, I'd suppose. But still a fan might be useful if you'll do it for a few hours (like I did).

Other excellent U.S. companies making generators are Winco 
(www.wincogen.com) and Gillette (www.gillettegenerators.com). I'm sorry, 
I don't have direct experience wrt RFI. Maybe contact the manufacturer 
directly for info.

Only due to two accidents - the large number of European teams and that
WRTC does not include any RTTY component.  When one looks at teams from
the Americas, N1MM Logger was the more popular logger.  When one looks
at the top performers in digital mode contests the results show a much
higher percentage of N1MM logger and WriteLog users.

Win-Test has its pace if one is stuck on a user interface from the last
century and is only concerned for CW (not that either is necessarily
bad).

Thanks all for the help on this. I receive the Elecraft list in digest

operational, Cary.

It pays to check the Elecraft website frequently.

At least I do, and updated to 4.86 shortly after it was released . . . 
announcement or no announcement.

Talk about burying the lede...  I have not heard any RFI from the generator 
(it is running it's weekly test right now!) whenever I have used the rigs 
while it is running.  My worst RFI offender is actually the Electrolux 
clothes dryer.  I do a lot of listening & playing with SDRs (including K3 
and KX3), but have mostly wire antennas.

Subject: Re: [Elecraft] OT GENERAC generators

We also have a Generac generator, and ATS.  I believe it's about 20kW, the
largest they sell that is NOT water cooled.  I didn't want a car engine...

Our house has two 200A panels inside, and being in South Carolina (hot,
muggy), we have three air conditioning units, including  mini-split for the
ham shack, plus all electric kitchen (induction cooktop), and other
high-current things.  I tried several electricians, all of whom wanted to
install 30+kW, water-cooled generators, which I could not afford.

We finally found an electrician (as part of a kitchen remodel) that was
smarter than the average one, and he was familiar with the Generac Nexus
(sp) line of "Smart Switches".  These are add-ons to the ATS that manage
generator loading by cutting back heavy loads if the generator gets bogged
down.  They add a switch to each identified load, and the ATS controls how
those switches get managed.

We've had the generator run a few times, and I've seen the ATS cutting back
the load at least once.  I'm usually home during outages, so I can manually
trip breakers to manage the load myself, but it's nice to see that the
system works even if we aren't home.

So far, I've been really happy with this setup.

This is very interesting. I've been thinking of all the ways you could spin this data other than simply counting radios. For example, Icom could say, "Five out of the top six winning radios were Icoms." Yaesu could say, "When Elecraft owner?Martti Laine needed a top performer for WRTC... he reached for his Yaesu!", Kenwood could say, "Think a Kenwood can't beat an Elecraft in a tough?contesting situation? Think again." &c.
?
I think what this all really?means is that it comes down to the operator, not the radio... which is the whole?reason for WRTC in the first place.

The months ahead will likely treat us to much advertising spin.

To a point.  Supposing the WRTC could be done all over again but the
winning team were given the TS-590S radios instead of the Icoms, would
they still win?  Of course, that is impossible to answer, but I will
note that no one showed up with an HW-101!

Yeah, it all depends on how you look at it. Back in the 2010 WRTC it 
was pretty much all Elecraft and Yeasu. Icom was there but not nearly 
as strong as this year.

When I look over these results I think of the way the drivers finish 
in NASCAR races. You pretty much know who the top drivers are, but the 
exact order of finish remains to be seen. And this is strongly 
affected by luck in a lot of cases.

I think the same here. The top 20 or 25 teams are all excellent ops 
with excellent rigs. But who snags a few rare multipliers is often 
more luck than skill. Gotta be in the right spot at the right time.

I note that the Russian team that won in '10 finished 16th this time 
around. A very respectable showing, but no longer 1st.

Yes, very interesting, and I think most of the credit goes to the 
operators, rather than the radios.

However, the fact that a very large percentage of these top operators 
*choose* to use the Elecraft K3 does say a lot about the desirability of 
the K3 for contesting.  Whether that be because of the weight, or 
because of the performance and operating interface, you would probably 
have to ask each K3 operator about his choice.

Don W3FPR

I cannot comment one way or another on the Generac, though I see them 
often advertised with farming equipment, so probably they are 
sturdy.  I think my Dad had one he ran with the tractor pto.

We chose to add a generator to our home after a cheaply built foreign 
model was unable to supply even enough power for a 75w light and the 
microwave.  We decided to go for a generator that was capable of 
running the whole house and had electric start (to make life easier 
on us old folks).  We bought a 6500w Honda Generator for about 
$4,000.  I built a "doghouse" to permanently install it near our 
meter and added a manual transfer switch.

We've had absolutely no problems with the generator other than the 
battery charge slowly drops in our winter temps, so I added a ac 
timer and a 500ma 12v charger.  It charges the gen starting battery 
twice/day for 3-hours and that solved the battery discharge issue.

What I especially appreciate is the slow-run mode that extends 
running time to 14-hours between refueling (about 3 gallons).  Like 
most Honda's it runs very quiet (I cannot tell it is running 20-feet away).

The generator is capable of supplying enough power for me to run my 
8877 (about 3kW load).
It is capable of remote control in the house (we didn't opt for that) 
and gen shuts down on high temp or low oil.
We do have to be careful not to run too much in the kitchen and the 
well pump when in the slow-run mode else it will trip off.  Never a 
problem in full-speed running.

Nice to have power when the winds blow and trees take down commercial 
lines (several times a year).

How much fuel do all you guys with whole house generators keep on hand?

How much fuel does one need to, say, go for 10 days?  Does everyone have 
that on hand?

What next, if you run out of fuel...


[--Note - not an argument, a serious question.  I know lots of guys with 
generators, but I bet they have only one or two days of fuel on hand. 
What does it really take?  Does one need a submarine-size tank, like we 
see in rural areas, to go the distance? ]

Good question.

OK here are the stats on my 30 KVA Generac.? Consider a normal day winter time and the power goes out at commute time.? After the calls to PG&E (in my area), we settle down to a evening without power, UNTIL.? The word comes that the power will be off for up to 24 hours.?? The freezer is good for over night so unless wife wants to watch TV, we set it out over night.? 


In the morning, I manually fire up the diesel and check the 25 gal tank level.? 2/3 full approx 16 gal.? Switch over the manual mains and we are on full power load.

PG& E was wrong on the estimate and did not have a solid eta on restored power.?? After running the Generac until everyone has had their showers, etc.? I shut it down for the night.? In the morning I check the fuel and it is at a little over 1/3 or 8 gal. I crank it up, start the day. About 3PM the indoor NE2 lamp on the commercial side of the panel comes on and I switch off the Generac.?? I refill the diesel fuel tank.? Estimate time on the RTM is about 21 hours running on 8 gal of diesel.? Yes, it has a idle mode but keeps the voltage above 100 VAC.??

Not bad.

Mel, K6KBE

15 KW Generac with 550 gal propane tank.  Live out in the country and  have 
gone 14 days without power.  I'm good for 2-4 weeks, depending on  load.

We have what ever is in the 500 gallon propane tank. If it were generator only, I don't know long it would last. Add in the furnace and it would probably only last a few days. Getting more would be a call to the propane company if they were still operating.

On huge advantage of a gasoline powered generator over a tank fed propane 
unit is that you can always syphon a few days worth of gas out of your car, 
but if the roads are closed and your LP tnak runs dry, your screwed.

 That said, the longest we've EVER been without power hear in northern 
Virginia is 4 to 5 days from some nasty hurricanes.  Typical storm damaged 
lines around here are restored in a matter of hours.

I have almost identical symptoms - brief audio dropouts, sometimes
solitary, sometimes many and frequent, rendering the remote setup unusable.
However, I'm NOT using WiFi connectivity between the RRC and the router. My
RRC connects directly to my Cisco/Linksys EA4500 router with a short RJ45
cable. Are there other settings in the router that might provoke similar
symptoms? I should have ample bandwidth on my cable TV Internet connection
- typically 20-30 Mb down, 1-2 Mb up, 20-40 ms ping.

Any thoughts?

Thanks & 73,

Suggest you find the EAxxxx menu that allows you to optimize SIP
and/or VoIP performance.  It is here on this EA9600 somewhere.  I
think all the higher-end Linksys routers have this setting.

Most remote audio uses SIP for call setup and one of several ULPs for
voice VoIP.  RTP is one of them.  Brandon at Elecraft knows a lot
about all this, and may be able to give more detailed advice.

How much fuel do all you guys with whole house generators keep on hand?

How much fuel does one need to, say, go for 10 days?  Does everyone have
that on hand?

What next, if you run out of fuel...


[--Note - not an argument, a serious question.  I know lots of guys with
generators, but I bet they have only one or two days of fuel on hand.
What does it really take?  Does one need a submarine-size tank, like we
see in rural areas, to go the distance? ]

---------------------- K8JHR ------------------------

I keep three 5-gallon plastic gas cans with fuel.  That is for 
running the lawn tractor (mows and snowblows) and the generator (also 
very occasional use a chainsaw and brush cutter).

That is sufficient for most power outages.  Fuel consumption in the 
econo-run mode is 0.2 gal/hour so 24 hours continuous use would use 
just over 5 gallons.  But we usually shut down the generator when 
sleeping unless it is during the cold of winter and we need to be 
concerned about freezing the water lines.

Longest power outage has been about three days.  We live only two 
miles from one of the power company generator sites so not likely to 
be out long-term.

When we run thru 15 gallons of fuel (might stretch five days 
intermittent running) then we drive to a gas station and 
refuel.  Unlike the lower-48 many gas stations have their own backup 
generators in case of power loss.  Here in AK we try to keep the cars 
fueled with at least half a tank so we could drive quite a distance 
if we needed to find an open station.  In a major disaster we would 
not have enough fuel to last two weeks (unless we siphon from one of the cars).

House heats on natural gas but we opted to stay with a gasoline 
powered generator.  Less dependent on gas supply that way.

Here's a question for the rest of you:  How much emergency food and 
water to you have?  One winter an avalanche cut off truck deliveries 
for three weeks and we almost ran out of dog food (had six sled dogs, 
then).  We had power thru that period.

A small town about 100 miles from here lost their electric and phones 
for that period and also all road deliveries (only one gas station in 
town).  National Guard air-lifted them a large gen-set and relief 
food (local grocery freezers thawed and there as no resupply for a long time).

I agree completely.  The rig and logging software have very to do with the
outcome.

The #1 team probably has a sore back and sore arms, from lugging 7800s there

I recently started using the PingPlotter network monitoring software and find
it quite useful for keeping long term data in graph format of my packet loss
with Comcast. 

  http://www.pingplotter.com/ <http://www.pingplotter.com/>  

The Free version does not provide long term monitoring.  The Standard
version is reasonably priced (around $30 I think) but the 30 day trial is
fully functional.

I do not know how it would work with remote station hosts, if they behave
like a normal server or not.  But if not one could still use it to track
problems that are at the first few hops by monitoring other servers like
google etc.

You can display graphs for each hop in the path to the server.  It is much
easier to use than manual trace route and ping tests to each hop.

Almost all of my packet loss is at hop #2 which is the first node past my
router.

How much fuel do all you guys with whole house generators keep on hand?

How much fuel does one need to, say, go for 10 days?  Does everyone have
that on hand?

What next, if you run out of fuel...


[--Note - not an argument, a serious question.  I know lots of guys with
generators, but I bet they have only one or two days of fuel on hand. 
What does it really take?  Does one need a submarine-size tank, like we see
in rural areas, to go the distance? ]

My experience says to use 1800 RPM vs. the more common 3600 RPM generators. They are less noisy, have half the wear-and-tear and almost one-half the fuel consumption of the 3600 RPM models. We too live off-grid, and have for 25 years, counting on solar PV systems for our primary electrical generation.

If you're going to ping something, do a traceroute and ping a router a 
few hops into your provider's network, or ping something like your 
provider's web server.

When you choose to ping something like Google, it tells you about your 
provider's network up to the first place they can get rid of your 
packets, and every other network up to the Google server.

The reason you want to look at something close is that you can either 
control it yourself, or you can complain about it to someone you pay.  
When you ping Google, your provider's SLA will carefully explain that 
they don't control the whole internet, and aren't responsible for 
anything beyond their own network.

A little number crunching of the results (because that sort of thing appeals to me... (the XYL says, "There's something seriously wrong with you.")) tends to support the idea that the hardware is not the primary factor for this contest. The results below are somewhat suspect in that only 'Radio 1' was considered, and all of the QSO's were attributed to that radio. (A better approach might be to split the number of QSO's between Radio 1 and Radio 2. I might dedicate some brain cycles to that.)
?
Interestingly, of the teams that made use of K3's for Radio 1, six of them used another brand for Radio 2, whereas teams that used something other than a K3 for 'Radio 1' didn't (with only a single exception (W1B)) make use of a K3 for 'Radio 2'.?
?
Given the number of K3's in the contest it's not surprising that 68% of all QSO's made were made by K3's. I hope the formatting holds for the table below. If it doesn't, e-mail me and I'll send you my spreadsheet.

Hey Fred,

You caught me at the desk with my K3. So I just tried it for you and yes 
changing to gray scale changed to gray scale on my external monitor. I 
only found the option to change the Waterfall color, not sure if there 
is an option to change the spectral display.

Subject: [Elecraft] KXPD3 Paddle Intermittent - At the hinge-posts ?
Message-ID: <1406316212495-7591582.post@n2.nabble.com>

Good afternoon, Gentlemen -

I have been experiencing intermittent contact problems on my KX3 paddle for
weeks now. ( I have read all the experiences on the group, and tried those
suggestions.) Sometimes I would gain temporary relief from dis-assembly,
cleaning, reassembly, but the problem always returned.

The main symptoms are "missing dit"; with easy wrist-rolling from side to
side, I suddenly come up with no dit where one should be. I learned I could
minimize this problem by "man-handling" the levers, but this was tiring (
that is, forceful lever movements seemed to solve the problem of
intermittent contact ). This seemed strange, since I could clearly "feel"
the movable contact stop on the post, even though no electrical contact was
completed.

Well, something FORCED me to have a better look into what was happening, and
I thought I would see if any of you have been experiencing this same
problem. I have recently been operating the KX3 set up as "hand-key" and the
automatic creation of proper length dots and dashes is no longer present to
cover up the frequently intermittent contact. So today, I followed a hunch
and connected two clip leads to provide ground from the chassis to each of
the movable levers. Sure enough, this put an end to the intermittent
operation. I repeated the test several times, and each time the intermittent
would appear without the clip leads, and disappear once the clip leads were
reattached. 

I followed this up with a power-off resistance measurement from each of the
movable levers to the chassis and, sure enough, LARGE resistances were
found. Depending on the amount of pressure exerted on the lever ( to load
the swing-lever/pin joint, the resistance could be varied from 8000 ohms to
1200, 800, all the way down to 1.3 ohms ). I went further to check the
resistance to chassis from the knurled-bolt KXPD3 fasteners ( 1.0 ohm ) and
the resistance to chassis from the top-place of the KXPD3 ( 1.2 ohms ). Only
the last part of the path to each lever seems to be involved in the
high-resistance problem ( the vertical hinge that supports and grounds each
lever ).

So, AT-LAST, my problem has been located. I am wondering if this has
happened to anyone else with the KXPD3? ( It looks like most of such
discussion peaked and went away in year 2012, so I am guessing I am the only
one with the problem ).

Love my KX3, and can't wait to get this one little quibble quashed :)

Jerry AB3SX

Shucks, fellers.  All that does not add up.

WE can rationalize this any way we like, but the fact is, 5 of the 6 
best operators did not choose a K3, and I know least one other happy K3 
owner used a Brand-X radio for the competition, and in all of his 
qualifying rounds.

Logically - If you say the rig does not matter, and it all turns on 
operator skill ... then no one can brag about any particular radio used 
in the competition for any reason.   We cannot have it both ways.
We cannot say the K3 is best because 70 percent of the field used one, 
but it does not matter what the winners used, because after all, it all 
turns on operator skill.   If the rig does not matter for the winners, 
it does not matter for anyone.

So the unfortunate bottom line take-away is the top three teams used 5 5 
ICOMS and one K3.

Again, if you claim the radio does not matter, then it does not matter, 
and we cannot claim any victory for any rig used in the contest.  That 
would be inconsistent.



Personally, I think the fact 70 percent of the field used the same model 
radio is significant, although it may just prove it is easier than other 
radios to ship and travel with.  Still... it is a big number.

Just MY take.

I finished a prototype of the little Bluetooth serial data interface for
my K2.
Just plugs in the back of the K2 on the KIO2's DB9 connector, drawing its
power from there.
 
The prototype seems to work fine. Have been running for about a week.
I'm presently using it with N3FJP's ACLog, and have tried it out with an

Yes, this has been discussed in both this reflector, and the KX3 yahoo group. Here is a blog posting from one of the guys who did this mod:

Very nice! My thing is I'm using that port for the kat100 tuner. ?If it could be wired directly to kpa100 serial and left inside the k2/100 that would be perfect.?

I finished a prototype of the little Bluetooth serial data interface for
my K2.
Just plugs in the back of the K2 on the KIO2's DB9 connector, drawing its
power from there.

The prototype seems to work fine. Have been running for about a week.
I'm presently using it with N3FJP's ACLog, and have tried it out with an
older version of Ham Radio Deluxe.

Subject: [Elecraft] XV144 Advice Needed -- And Another Manual Goof Noted
Message-ID: <53D2DBD5.7050506@audiosystemsgroup.com>

I've reclaimed an XV144 that I bought used in 2005 and have never used 
from a friend to whom I loaned it. I'll be using it with a K3, that will 
be dedicated to 2M. I'm told that frequency stability is a concern, and 
that it's important to drive it at the "right" level so that fixed 
attenuation is not switched in to protect the TX input. The question is, 
what is the "right" level to minimize dissipation inside the XV144? So 
far, I haven't found that in the manual or the specs.

Another observation. The latest manual for the XV-series converters 
contains another massive goof in the wiring of the AUX cable. It shows 
only two conductors with no return, depending on the coax to carry a 
return signal. That's fine for DC, but our stations produce RF, so the 
large loop formed by the coax and the control lines is a big antenna. TILT!

Time for another manual re-writing. And to fire the guy who conceived 
the drawing.

I think that the rig is not very important. One tidbit to support this 
theory, although far from conclusive, is to compare what happened to 
the OE3DIA team in 2010 vs 2014.

In 2010 there was a nasty lightning storm the took out both of this 
teams K3's. They were knocked out about 1 hour into the contest. But 
Yaesu had some reps on site and they had a pair of FT857's which they 
loaned to the team. They lost about an hour in the switchover. So they 
ran for 23 hours while the other teams ran for 24.

If you compare their score at the end of the contest to the other 
teams after 23 hours (the hour-by-hour scores was available on the 
Russian web site for a while after the contest) they were in about the 
middle of the pack. This is using K3's for 1 hour and FT857's for 22 
hours.

In 2014 I see no notes about anyone suffering such a loss and the 
OE3DIA team finished 22nd out of 59. Again about the middle of the 
pack. I think this somewhat better than their 23 hour comparison in 
2010, but not a lot better.

This would tend to indicate that - when in the hands of very competent 
operators - a pair of lowly FT857's is nearly as good as a pair of K3's.

Now, don't get me wrong here, I'm not saying the FT857 is as good as a 
K3, it is *not*. No doubt about that. In fact, it is not as good as a 
K2. I have those two sitting here side by side and I can assure you 
that the K2 is the superior rig. What it says to me is that the K3 and 
others of its class are somewhat overkill. The lowly FT857 is 'nearly 
good enough'. Certainly not great, but 'nearly good enough'.

I think you're correct Dave.  Unlike all other contests, WRTC is 
refereed and everyone uses identical antennas and power ... about as 
level a playing field as you could ever create.  WRTC *is* structured to 
focus on operator skills vs station excellence, 100W is 100W in that 
situation, it doesn't really matter which rig generated the RF. 
Mandating a specific radio would put all the ops who don't use that 
radio in everyday contesting at a big disadvantage.

There could be some small advantages on receive, I imagine they were 
confronted with pile-ups earlier in the contest, but eventually, they 
likely worked everyone they heard, and I doubt there would be much 
difference in what one could hear on a K3 vs a 7600, FT1000, or other 
radios.  They're all either current state-of-the-art radios or close.

The one factor that using different radios does not control for is 
spurious emissions such as key clicks and phase noise.  There *is* a 
wide difference in those between the radios.  Don't know if that would 
turn out to be an issue in the WRTC environment, although I sure know it 
was when my "neighbor" Jack, KF6T, was running a Yaesu rig with serious 
phase noise problems.  Of course, if clicks and phase noise was an issue 
at WRTC, it would impact everyone else negatively.

Jim,

I am looking at the XV transverter Owner's manual Rev F1 and cannot 
understand your statement about the ACC cable.  See Figure 7 on page 
11.  It clearly shows 4 wires to the ACC connector, and one of them (pin 
1 of the XV144 DB-9 connector and pin 12 of the K3 ACC end) is the 
return path.

I am also concerned about your statement about the "right" level drive 
to the XV144.  In the XV144 there is no provision to switch in any fixed 
attenuation.

Are you certain you are looking at the XV Transverter Owner's manual and 
*not* the K144XV internal option for the K3.

As for frequency stability of the XV144, without the crystal oven, the 
XV144 is usually stable enough for CW and SSB operation.  If greater 
frequency stability is desired, the addition of the crystal oven is 
desirable.  Plug the JP-9 header to pins 4 and 5 to provide power to the 
LO and xtal oven at all times that +12 volts is supplied to the XV144 
for the greatest LO stability.

73,
Don W3FPR

Yes, I just discovered the error -- it's my printer, that didn't 
reproduce two color
conductors.

It's on the control board in the form of relay K7 and three 160 ohm 
resistors.

I'm looking at an XV144, manual dated 2013.

Yes, I'm aware of the option for an oven.  In a quick conversation while 
he was rushing to make the flight to CT, K6XX alerted me to the 
stability issue, and said to choose drive levels to avoid dissipation in 
that attenuator.  So I'm trying to get a handle on roughly where it 
switches in.  He also suggested running XV at the minimum level needed 
to drive an external amp, which also makes sense.

After studying alignment instructions, I'm seeing a K3 output level of 1 
mW, so perhaps that's it.

Thanks and 73, Jim

Jerry ?

The cause of the problem is pretty well understood - the route to ground
is through the pivot pins, and their contact with the grounded pivot-pin
socket is unreliable.  It may be that your manhandling the levers put
enough stress on the assembly to drive the pins into their sockets for a
while.  

I too tried the Deoxit route, which worked for a few months.  A couple of
weeks ago I adopted the suggestion several people have made here - wire
the spring-holder screws to the ground terminal on the chassis plug (on
the paddle) and the problem is solved.

Turns out to be pretty easy.  I soldered a wire at its mid-point to the
long lead going from the paddle?s circuit board into the plug?s ground
point, then threaded each side to the spring-holder screws, backed those
out, wrapped the wire around the screws, tightened them down, and that?s
it.  The wire was a single strand from a small-guage speaker wire.  It is
almost invisible.  I can take a photo if you like - email me off-list

Subject: [Elecraft] XV144 Advice Needed -- And Another Manual Goof Noted
In-Reply-To: <53D2F318.50809@audiosystemsgroup.com>

Hello Jim,

I was once a XV144 user.? In my previous setup, I set the XV144 for the minimum drive from K3.? The output from KXVA3 can drive the XV144 to its full power.

In terms of power and frequency stability, which are the typical issues with XV144, apart from installing the oven, the contact points among the chasis and RF connectors MUST be properly sanded with sand paper to ensure good contact.

Heat issue is another concern.? The XV144 will be very very hot to operate at FM mode even at the factory stated specification of half output at 10W.? For light duty cycle, heat issue is not that apparent.

Hope this help.

73

Johnny VR2XMC

Yes, I just discovered the error -- it's my printer, that didn't 
reproduce two color
conductors.

It's on the control board in the form of relay K7 and three 160 ohm 
resistors.

I'm looking at an XV144, manual dated 2013.

Yes, I'm aware of the option for an oven.? In a quick conversation while 
he was rushing to make the flight to CT, K6XX alerted me to the 
stability issue, and said to choose drive levels to avoid dissipation in 
that attenuator.? So I'm trying to get a handle on roughly where it 
switches in.? He also suggested running XV at the minimum level needed 
to drive an external amp, which also makes sense.

After studying alignment instructions, I'm seeing a K3 output level of 1 
mW, so perhaps that's it.

Thanks and 73, Jim

Now that I've studied the schematic a bit more, I realize it's the 
resistors switched in and out by JP3 and JP4, and the gain stage Q6, 
that can be bypassed or not, as set by JP5 and JP6.

For the K3, instructions are to bypass the resistors, activate the gain 
stage, and set the K3 for 1mW.

So I've got my answer, I think.

73, Jim

Message-ID: <B5CA21CA-D2D9-40B2-95D4-744A1C078858@yahoo.com>

If you want quiet I would stay away from Generac. We had a 5K one for backup power for our house in Colorado. First time I fired it up for a test my neighbor from 1/2 mile away came down to ask me what was wrong. We've since used the Honda quiet generators in Quartzsite for several years and you can carry on a conversation within 5 feet of one. Biggest problem is you have to have several linked together for any higher power requirements but they are very quiet. (and stolen a lot.)

A friend of ours had a propane powered generator in his cab over. Didn't like it at all because it ran off the same tank as his heater and stove. Biggest problem with it was propane has less power per volume than gas.

We use 320 watts of solar on our RV when camping out in the desert with an 3 cylinder diesel backup generator by Onan if the sun don't shine for a while. Runs off the diesel tank in the MH and seems to last forever. Fairly quiet too as it is a DC generator feeding a 8kw inverter. Only runs as fast as it needs to to supply enough DC for the inverter so you can tell by the sound of the engine when it's loafing along. I could probably figure a way to plug it into the house if we needed to in an emergency. (or just live in the motorhome for a while.)

My choice would be  to have some of everything, solar, wind and backup generator. Whether gas or diesel generator would depend on the ease of supply.
A friend of mine has solar and a wind generator and I've seen it put out 35 amps but it can be scary in a high wind.

Fred,

Not really.  It would very much effect those individual stations in the 
respective close area 'group' of the offending transmitter.  And there were 
three of four fairly large 'groups' of stations.

The other groups and the more widely spread stations would not be affected 
with the exception of perhaps on 80 Meters.

Jim,

With the XV144 jumpers set for 1 mW drive, the attenuator resistors are 
bypassed, and the Q6 gain stage is in-line.

The attenuator resistors (and the Q6 amplifier) are put into line (or 
out of line) with the plugging of  JP3, JP4, JP5 and JP6.  There is no 
dynamic switching - the XV144 is plugged for an input level ranging from 
1 mW to a maximum of 8 watts.  Once plugged for a particular input 
range, the Input Attenuator pot can be adjusted for any particular input 
level within that range.  There is no automated switching of the 
attenuators or the 28 MHz Q6 gain stage.  It is all in the way the 
jumpers are plugged.  It does not "switch in" - the user has to 
determine the drive level that is to be used and set the jumpers 
accordingly.

If you are using the K3 (or K2 with the K60XV) to drive the XV144 (and 
have the KXV3 option), set the TRNxx menu to  provide 1 mW (maximum) 
drive and set the XV144 jumpers to the 1 mW input level.

Then drive the XV144 with that 1 mW signal and adjust the Input 
Attenuator pot to produce 20 watts with the full 1 mW drive.  The K3 
(K2) power knob will then adjust the power drive to the XV144 up to 1 mW 
and will control the XV144 power output up to 20 watts.

Relay K7 has nothing to do with the setting of the power level (via the 
jumpers).  It always activates on transmit.  If the jumpers are set to 
JP3 and JP4 plugged to pins 1 and 2, the attenuator is bypassed.  
Jumpers JP5 and JP6 select whether the Q6 gain stage in in-line or 
bypassed.  For 1 mW input, you want the attenuator to be bypassed and 
the Q6 gain stage to be in-line.  That means JP3 and JP4 are plugged 
between pins 1 and 2 and JP5 and JP6 are plugged between pins 2 and 3.

Relays K6 and K7 control the path between transmit and receive so that 
both Q6 and the attenuator resistors are bypassed during receive and 
respond to the jumper settings during transmit.

73,
Don W3FPR

Hi
Is there a way to shorten the 'diddle" at the end of an fsk transmission when you are using the internal fsk decoder/encoder programmatically??
I know that in the k3 utility you can set the length of this but what if you are not using the utility and writing you own code??
Thanks, Tom?

As you can see from my last post (which crossed in the mail with this 
one), I studied the drawings and jumper settings and figured it out.

IMHO the most of those participants who had to travel long way have chosen 
the lightest out of the best radios. And K3 is unbeatable in that respect.

Unfortunately in WRTC2014,  locations were much different and very often 
that was the most important factor affecting the final standing.
"You can't work them if you don't hear them"
See these HFTA plots for comparison.

According to those  who participated both in WRTC 2010 and WRTC 2014, the 
former was much more level field in that respect.
Besides radio and operating skill one had to pull out right operating 
position. And this explains why some top notch ops like for example CT1BOH 
or ES5TV are well below the middle of the list in the final standing this 
year.

Yes. Just send "..--" (think of it as the prosign "IM", or "IMmediately stop transmitting"). This terminates both FSK-D and PSK-D transmissions within about 1 second.

I'm not at the rig at the moment, but I believe you can also send an EOT character to stop the diddle.

Jim - I fitted an internal fan in my XV144.  Look at the XV432 manual.
It means drilling a circle of holes in the PCB where the fan is fitted.
Also, make sure you have some vent holes in the top cover (Early XV144s
did not have them).

Propane, in a sealed tank under pressure, tends to have good shelf-life.

Gasoline, stored in a vented tank, tends to turn to varnish.

A tank of diesel will support bacteria growth, which clogs the filter 
(when you need it most).

If we're talking about an emergency generator that is used infrequently, 
then propane is a really good choice.

This is an issue where systems engineering comes into play. I live in 
the Santa Cruz mountains, where we lose power for a few hours or a few 
days a few times a year. Causes include storms that drop limbs onto 
power lines, disruptions because sections of the grid are shut down to 
support fire fighting, or because line. So far, (8 years) we haven't 
encountered an earthquake, but that will set up longer outages and other 
issues.

We heat and cook with propane and have no Air Conditioning -- our 
electrical loads are home appliances like refrigerators, lighting, home 
entertainment, computers, and well motors. I've moved everything but the 
well motors and big electrical loads (like a microwave) to one side of 
120V, and can run it quite nicely from a Honda 2000i running in econo 
mode. That drinks very little petrol, and we let it rest when we're 
sleeping. Internet, local WiFi, and other crucial systems are backed up 
with batteries that are float charged with wall warts and can run for 
days. In my shack, everything but computers and power amps run on big 
batteries that are charged by solar.

We have a much bigger 240V Honda that can handle the well motors and 
drinks a lot more gas. 90% of our outages are handled by the 2000i, and 
we fire up the big one only when we need more.   The well has two pumps 
-- one that pulls water up 100 ft to the tank, and another that 
pressurizes the system. Our water tanks are a few tens of feet above the 
house and hold a lot of water, so we can go for a while without running 
the pressure motors and well pumps. Not a lot of pressure, but enough 
until we need to take a shower. Laundry can almost always wait. We 
haven't used A/C since we left Chicago in 2006.

I suggest that anyone contemplating a generator do this sort of system 
engineering.

Message-ID: <CAM-vB2MU_dRbne1M5P2MdC=K+uB1voRfUXW-+wv6TBVWHxCurw@mail.gmail.com>

Was on 40 meters trying but unable to zerobeat a CW carrier with my K3, and
noticed that the gradations in tone from this signal were not continuous
but were in intervals.  QSY'd to 20 and the signals were OK, and when
coming back to 40, was able to spot tune a CW signal.
This is an intermittent issue and not a common one, but it does happen from
time to time.  Any ideas would be appreciated.  Perhaps there is some sort
of intermod mixing that creates this distortion.  Anyone else notice this
problem?  If I had to graph this problem, it would be with a step function.

If it were a musical instrument producing these non-continuous tones, I
would say the instrument is unable to play chromatic scales.  This issue
typically goes away quickly, but is puzzling.

Hi Paul.

First you have to make sure you have the lower area visible on the external
monitor. If not, turn it on in the SVGA section of the P3 menu.

Next, be sure that you can see decoded text on the K3 lower display. If not,
turn it on by holding the CWT button and rotating the VFO B dial until it
says ON. Then adjust the threshold accordingly with the VFO A dial. My
threshold is on 3.

And finally, if you are decoding RTTY make sure your DATA MD is AFSK A at 45
bps (not 75 bps).

Mike K2MK

Message-ID: <CA+8EV6pumZAfVz033J2buMu_rEtLEVBGpKnYT5hE1A6vTgymgQ@mail.gmail.com>

Hi guys:

Lesson learned!  I should not be attempting remote ops to my station on
Maryland's Eastern Shore during the summer months.  We get lightning
strikes, and I got creamed a couple weeks ago.  Everything was hooked up,
and I am now having to replace my Orion 2800 rotor, and repair or replace
my Green Heron RT-21 rotor controller, my TopTen band decoder, my Alpha DAS
band decoder and some PolyPhaser lightning protection gear at the tower.
 The PolyPhaser failed to protect the rotor, and the rotor and relay lines
from the tower run 350 ft. to my house.  I needed protection at both ends.

I will be a long time coming back from this.

Now for the Elecraft part of this long whine...

The good news:  The K3 and the KPA500 survived.

The bad news:  The KAT500 is not behaving.  It is not going through its
normal tuning cycle, and the one or two times it did, into a dummy load, it
left all the SWR lights on.  That is not normal.  if the K3 shows SWR= 1.1,
the KAT500 should show the same.

I can connect to the KAT500 from the PC using the KAT500 utility program,
and that is all normal.  I loaded in the last set of good parameters.  This
made no difference.

Anyone have any troubleshooting steps to suggest?

And, my W2 Wattmeter is completely dead, no lights at all.  Or only a brief
flash of all the top line of yellow lights, and then nothing.  I cannot
talk to the W2 using the utility program.  I have no idea if the
directional coupler survived.  Same question --- where do I begin?

I will try to send both to Elecraft for repair, but if there is something
simple I can do here, that would be great.


Thanks for any help you can provide.

73 de Brian

Message-ID: <BLU178-W373B1AEF0F936896C41A31D9FD0@phx.gbl>

I'm fooling around with custom portable Vertical array antennas for portable and DXpedition use.
I was wondering if anyone in our list Brain trust had a favorite way to cut wires to a (reasonably precise) 1/4-wave length. 
(Yes, I can measure and No I don't want to model, I want to field test and calibrate.)
What I want to do is have an elevated vertical (say base at 8'-10'), and add a temporary 1/4-wave "reference" counterpoise wire with a 20-degree downward slope.
Then, use this set-up to adjust whatever physical items I'm using for the vertical element to get a 1:1 match, calibrated to the radials length.
I want to end-up with a balanced antenna that is resonant and does not require a tuner (given that I'll have some minor adjustments to fine-tune the antenna's match at different locations).
So, theoretically, the vertical could be made of 6-inch diameter aluminum tubing (not likely in the field), insulated or non-insulated wire of any size, or whatever.
I'm also curious about and I to be able to see what the differences are in the lengths of antennas based on what materials of different types and sizes that I use.
Ideas???
Thanks.

I had a similar event.  It took out my Yaesu rotor and control box, SteppIR controler board, and my KAT500.
Like you, my K3 and KPA500 wre A-OK
I sent KAT500 to Elecraft for repair and mine acted just like yours. (you must get an authorization # before sending).  It was DOA @ Elecraft and cost of new board about equal to a new KAT500 - bummer.
Good luck, I'm installing polyphaser's on SteppIR and new Yaesu rotor control lines this week.

I have a gasoline powered unit.  Dismissed propane because of the cost 
of the tank/tank rental and the minimum yearly fee for propane --whether 
you need any or not.  These costs ended up being too high for a few days 
a year of generator use.  We're in the sticks and don't have competition 
in the propane market.

I suggest one look into the details of how propane is sold in your area 
before buying a propane fired generator. YMMV

Interesting project.   My generalist, non-expert suggestion.  There are 
many variables you must consider, not the least of which are the 
electrical properties of the components, such as the length, velocity 
factor, diameter, resistance in circular mils, inherent impedance and 
capacitance of any conductor or radiator, the effects of any dielectric 
present, capacitive and inductive coupling with other objects in the 
vicinity, and many other factors.

I am a big fan of verticals, but I usually work in the other direction: 
  I set the length of the vertical element, and adjust the length and 
angle of the radials to effect a good match, but, it sounds like you 
want a set, or multiple sets, of known radials as an ersatz control 
group, against which you will judge the effects of different vertical 
radiators.

I suggest you consider and measure / record all the factors you can, and 
build a set of control radials for your experiments, and use them for 
each individual experiment, and see what happens.  You cannot control or 
account for all factors, but unless you start someplace, you will go no 
place.  Build a set of radials and use them as a reference, and see what 
you get... assess the data... regroup... re-formulate ... and determine 
what to do next.

I suspect the guy to ask is Rudy Severns, N6LF, who is the guru of 
vertical antenna testing.

Happy days, good luck.

Hi, Thanks for all the responses. I tried them all and the results are below:
1) Send vertical bar....nope doesn't work

2) Send IM prosign: doesn't seem to work in FSK or PSK. The actual letters IM are transmitted?


3) Send EOT character: Works!


Thanks for all the suggestions. The app will be out shortly.

Hi Jim


The version of the manual I have clearly shows on page 8 the three levels in mw and watts based on jumper settings.
And Appendix C Page C-1 again gives the details and jumper settings for the tree levels, up to 0dBm, +24 dBm and + 39 dBm.


Appendix Page A-5 Schematic There's a problem?  I don't see it...

I have used a 5500 w Honda for many years the only problems with it have
been gasoline related as with all gas models. The Honda has been an
excellent choice and mine still has many years of use left, that said this
fall we will be up grading to a propane Generac. I just bought a used 1000
gal tank to tie into my 500 gal line for house and generator. This is the
cheapest and most dependable route to go for fuel and by far the safest to
handle, store, keep fresh. My first choice would be natural gas if it were
available to me.



73 & Good DX,

I have a gasoline powered unit.  Dismissed propane because of the cost of
the tank/tank rental and the minimum yearly fee for propane --whether you
need any or not.  These costs ended up being too high for a few days a year
of generator use.  We're in the sticks and don't have competition in the
propane market.

I suggest one look into the details of how propane is sold in your area
before buying a propane fired generator. YMMV

Hi,

what would you think of a six-band module ?
Would it be interresting for the elecraft K1 users ?

I am think about build one. With afined design which 
is easier to align with different trim capacitors !

Your opinion ???

I'm happy with my 4-band module. Works great. And 
added backlight yesterday: A very nice rig.

A six-band module would be good if you wanted 
80-40-30-20-15 and one other band. I've never 
operated QRP on 80, except PSK31 with the PSK-80. 
Usually too antenna challenged when portable for 
QRP on 80, and at home QRN is bad a good part of 
the time.

Before doing a six-band module, make sure the MCU 
will support six *simultaneous* bands in the K1. 
Seems like new territory, so Wayne would have to 
weigh in.

Mike,

Think of it as tuning up on top of an existing QSO.  You're using 
Google's bandwidth, but not in any way that supports Google.

If lots of people "tune up" on top of Google, they have to address the 
unwanted traffic, or throw money at the problem (buy more bandwidth).

Courtesy suggest that you can dial off a bit, and still "tune" just fine.

A traceroute from my workstation goes through Verizon DSL, through 
Alter.net (belonged to MCI last I knew) and then to Google's network -- 
11 hops through 3 networks.

Pinging Google means I'm measuring the performance of ten routers, 
Google's web server, and the wires in between.

So let's say I'm measuring loss between here and Google, and it's at 
Alter.net.  I call them and say "your network is dropping packets" and 
they say "can I have your customer number?"  If I call my provider 
(Verizon) they refer me to their SLA (Service Level Agreement).  This is 
a consumer DSL line, so the SLA says "provisioned casually" which is 
internet-speak for "we promise that it might work some of the time."

If you're trying to figure out the performance of your connection (and 
diagnose/fix problems) you want to know what happens in the first few 
hops.  You want near zero packet loss and low latency and jitter, and 
you can work with someone you pay if there is an issue.

Beyond that, you can only hope.

Speaking as someone who ran an ISP for a couple of decades, I'm most 
interested in the first router past my facility.  Looking at the 
traceroute to Google, the 1st is my local router, 4th hop answers ping, 
the 5th doesn't respond to pings at all, and the 6th belongs to someone 
other than Verizon.  I'd ping the 2nd or 4th.

Does that help?

73 -- Lynn

P.S. I'm not a big fan of Google, but the same applies to MSN/Microsoft, 
Yahoo!, or any other well-known site that is likely to be up at all times.

Clearly YMMV, and we're all trying to solve different problems.

My gasoline generators were a constant maintenance hassle because the AC 
power was so reliable that they were very rarely used, and I was 
constantly cleaning varnish out of the fuel system.  My loads were small 
enough that a portable (100 pound) propane tank was more than adequate.

If you have an outage every couple of months, then you aren't going to 
have trouble with stale gas.

Also, if you plan on siphoning fresh fuel from your car, make sure you 
can get past the anti-siphon baffle.

My favorite solution for intermittent backup is at http://priups.com.  
Enough to make me think about buying a Prius.

HelloThe latest release of Win4K3Suite (v1.63) now includes a CW - FSK-D PSK-D terminal that uses the built in decoding of the K3 and KX3 for these modes.
This new terminal offers 16 messages per file, custom layouts, QRZ support for call signs and more.
You can see a screen shot at?http://va2fsq.com/?page_id=612
This terminal can also be used in conjunction with the SVGA or as a replacement to its text mode to allow you to use only one keyboard.


Also new in this release, a reworked Spotting function that allows Auto spotting or manual spotting by right clicking on the Spot button as well as numerous other improvements.


If you haven't tried the software yet, please give it a try. It inter-operates seamlessly with almost all third party logging, control, contesting and third party panadapter programs allowing you to keep your favorite logging application but have a comprehensive control program that has no equivalent.


You can download a fully functioning 30 day trial at

Hi Craig,

What you are describing is an antenna in the dipole class, an antenna
with two poles. Similar to an inverted vee rotated by 225 degrees. The
half wavelength for the sum of the two elements will determine the
resonant frequency. The total length will be near the classic 468/MHz =
length in feet.

The easy way is to make the antenna a little longer, measure the
resonant frequency with an antenna analyzer, then scale to the desired
frequency, for example, for 14.05 MHz.

468 / 14.05 = 33.3' make each element 1/2 of 33.3' plus about a foot, or
17.5' each. Using an antenna analyzer, measure the resonant frequency,
it should be close to 13.4 MHz. Divide the measured frequency by the
desired frequency, for example 13.4 / 14.05 = 0.954. Multiply the start
lengths by the ratio, 17.5 * 0.954 = 16.7' for each of the two lengths.

The above antenna will require a current mode Balun, for example the
Elecraft BL2.

Also, when modeling the gain pattern, it has about a 3 dB front to back
gain ratio. The front being the side with the horizontal wire.

I hope this helps,
John KN5L

Those levels are the MAXIMUM drive that should be used with each 
corresponding jumper settings.
Once the jumpers are set, the Input Attenuator pot can be adjusted to 
set the desired output power.

If set for the +39 dBm input, the attenuator is inserted into the 28 MHz 
transmit path and the 28 MHz gain stage Q6 is bypassed.

The +24 dBm setting bypasses both the attenuator and the Q6 stage.

The 0 dBm setting inserts the Q6 gain stage and bypasses the attenuator.

If one is concerned about heat from the 3 watt resistors in the 
attenuator, it is only a problem when the +39 dBm input level is selected.

If one is using a K3 with the KXV3 (or KXV3A), set the jumpers for the 0 
dBm max input, set the chosen  K3 XVn PWR menu parameter to L 1.00 and 
set the XV144 JP1 to pins 1-2 and JP2 to pins 2-3 (for separate TX and 
RX coax on the 28 MHz IF).
Then transmit with the K3 power set at 1 mW and adjust the XV144 Input 
Attenuator pot for 20 watts output.  The K3 power knob will then control 
the drive to the XV144 and thus the desired output level.

Gasoline storage is easy....use fuel stabilizer...one oz to 2-1/2 
gallons of gasoline.

But you should run any gasoline engine regularly to keep it in good 
working order.  Once/month long enough at least to reach operating 
temperature.  This keeps oil in bearings and seals in good shape.

I know most just park their lawn mower over winter with gas in the 
tank.  But an expensive gen set needs a little TLC to keep running 
well...like changing the oil and filters (oil and gas).

We have enough outages that fuel is not stored longer than a few 
months (and I use stabilizer).

While this is getting to be long, I think this excerpt from a generator manufacturer sums it up best.


Generator set exercise
Generator sets on continuous standby must be able to go from a cold start to being fully operational in a matter 
of seconds. This can impose a severe burden on engine parts. However, 
regular exercising keeps engine parts lubricated, prevents oxidation of 
electrical contacts, uses up fuel before it deteriorates, and, in 
general, helps provide reliable engine starting. Exercise the generator 
set at least once a month for a minimum of 30 min. loaded to no less 
than one-third of the nameplate rating. Periods of no-load operation 
should be held to a minimum because unburned fuel tends to accumulate in the exhaust system. Whenever possible, test the system with actual 
building loads in order to exercise the automatic transfer switches and 
verify performance under real-world conditions. If connecting to the 
normal load is not convenient for test purposes, the best engine 
performance and longevity will be obtained by connecting it to a load 
bank of at least one-third the nameplate rating. Be sure to return the 
generator control to AUTO at the conclusion of any maintenance.

Mel, K6KBE

working order.? Once/month long enough at least to reach operating 
temperature.? This keeps oil in bearings and seals in good shape.

I know most just park their lawn mower over winter with gas in the 
tank.? But an expensive gen set
 needs a little TLC to keep running 
well...like changing the oil and filters (oil and gas).

We have enough outages that fuel is not stored longer than a few 
months (and I use stabilizer).

Subject: [Elecraft] Best Way to Make a 1/4-Wave Reference Wire?

Craig,

OK, so you want to have an electrical quarterwave resonator and 
electrical quarterwave radials.

I would suggest that you first cut two radials - make them a bit long 
and put them up at the height and slope that they will eventually be 
used.  Connect these two radials as you would a dipole - then measure 
the resonant frequency.  Adjust the length as needed to resonate at your 
desired frequency.
Note that these wires being close to the ground will not conform to the 
usual "cutting formula" of 486/frequency in MHz, so start plenty long.  
Trim the same amount from each end to keep both radials the same 
length.  You should now have 2 wires each an electrical quarterwave long 
in the position they are to be mounted.

Once you have those two radials tuned - disconnect the one connected to 
the coax center conductor (leave the one connected to the coax braid).  
Connect the center conductor to the vertical radiator and adjust the 
radiator length for resonance.
You will find this procedure in ON4UN's Low Band DXing book.  He does 
use a buried radial field to adjust the length of the radiator, but I 
assume you do not have one of those handy.

OK, you have the vertical and one radial tuned for certain - remove that 
radial and check that the other radial is also correctly tuned - adjust 
its length as needed.

If you plan more than 2 radials, tune each of them (one at a time) to 
resonate with the previously tuned vertical.  When all have been tuned, 
you may connect all the radials together.

If you want a simplified process that yields essentially the same 
results (for practical purposes) - put up the vertical radiator cut to 
the normal formula.  It may not be exactly a quarter wave, but it will 
be 'close enough' - yes it may produce something like a slightly 
off-center fed system, but it will not be so far off center to make much 
difference.
Now connecting each radial (again one at a time) trim the length of the 
radial to make the resonance point at the frequency you desire. 
Disconnect that first one and continue with all the other radials 
planned.  When finished with all of them, connect all the radials together.

That is my standard procedure for tuning elevated radials.  With 
elevated radials, only 2 are required to cancel the horizontally 
polarized radiation - if they are placed 180 degrees apart.

That works in K3 memories and from K3 Utility - the vertical bar is

Yes, supported by most loggers.

Hi Fred,

Question 1 is easy because you already guessed the answer. 

Question 2, not so easy.
The available display resolutions for the P3 SVGA adapter can be seen in the
SVGA manual.

On a general note, a modern LCD monitor will be able to serve double (or
triple) duty because they all seem to come with multiple inputs these days.
If your PC has 2 or more video outputs you can set up the secondary monitor
to run on its DVI or HDMI input from your PC. Then you can push a button (or
toggle a menu function) on the secondary monitor to either display the P3
SVGA input or the DVI or HDMI input from the PC. That's what many of us do.
But you would not use it for N1MM or some other critical application as you
would need that full time on your primary monitor. You might put your VE7CC
cluster program on the monitor shared with the P3.

73,
Mike K2MK

Our generator dates to the great northeast ice storm of 2008. 
That is the first and last time it was used "for real". Since 
then it has had its oil changed once a year after running it for 
1/2 hour. We run it until the gas tank is dry and have had no 
problems with starting or running.

Fuel for the generator is kept in 5 gallon gerry cans and cycled 
through our vehicles regularly.

The house was built in 1793, so can be used without electricity. 
During the ice storm we had one room just above freezing and one 
below -- walk in refrigerator and freezer.  Two wood stoves and 
5 fireplaces cover the heating and cooking needs. Candles and 
oil lamps provide light, and we can go to bed earlier than 
usual. :-)

The XYL likes indoor plumbing, which requires running the well 
pump. The oil burner also helps keep the house more livable for 
less work than the two wood stoves.

During the 5 days we were without power after the ice storm, the 
well pump and the furnace were the two loads we "had" to run. We 
also ran some lights, a coffee grinder etc. The local gas 
stations were open, making filling the gerry cans easy.

We are still trying to nail down our real needs to prepare for 
the next extended outage. In addition to ice storms, hurricanes 
happen, and tornados have taken out the power lines from a major 
generating station leaving Huntsville AL without power for 
several days. (My XYL arrived in Huntsville with an inverter and 
was very popular because she could help people charge cell phone 
batteries from autos.)

TCP/IP insures delivery, not performance. It is a mesh, not a point to point connection

Every router along the way is subject to congestion and packets can take different path if conditions warrant. There is no way to control the path once it is past gear in your control.
You could go over a top tier backbone, or you could go over Bob?s Ammo Bunker and Internet Service.

Our last major ice storm left us without electricity for 17 days and we used
$370 in gasoline for the generator being used concretively. Most gas
stations were without power for the first week.

Jorge,

If you are talking about the K3 IF output, there is nothing to activate.
Connect a known working receiver tuned to the K3 IF frequency of 8.215 
MHz and you should be able to hear the same signals as the K3 is hearing 
- you may have to tune a couple kHz in either direction to find it, but 
the signal should be present.

If you have a signal generator connected to the K3 input, the signal may 
be easier to find because it should be the only signal present.

If you have an older K3 (prior to September 2009), you will likely want 
to add the IF Output Buffer Gain Modification which increases the signal 
level at the IF output by more than 10 dB.  See 
http://www.elecraft.com/K3/mods/IF_Output_Buffer_Gain_Mod_Rev_A.pdf

The KX3 output is RX I/Q which is *not* an IF output (unless one 
considers baseband as a valid IF).
It can connect directly to a soundcard, not a receiver (SDR-IQ is a 
receiver).
Yes, it must be turned on in the menu.

Yes, his reference to IQ as in SDR-IQ made me 
wonder which rig he had in mind, since he didn't 
say and I've never dealt with an SDR-IQ.

Thanks to themany who responded tomy question about Generac generators.

It is highly likely that wewill purchase awhole house model before next 
winter; sizeto be determined after consultation with my electrician.  
The best choice here in rural Nova Scotia is propane.  Natural gas is 
not available and probably never will be.  We already have a propane 
cook stove and it is wonderful. The generator will have its own tank.

Thanks to all

Subject: [Elecraft] XV432 Demon Exorcism Operations
Message-ID: <etPan.53d44489.6b68079a.37e@K2QO-Mini.local>

Hi Gang,

I have an XV432 that is giving me fits. While my XV222 works FB with my K3/KXV3 combo, or any other IF rig for that matter, the XV432 has only worked well with my FT817 and 5W drive. While getting stuff together for the August UHF Contest, I now cannot even run the XV432 with the K3 because as soon as I select it, the radio locks up. The display is on but the buttons on the radio do nothing. The only remedy is to put the power cord from the radio and disconnect the I/O cable. Does not matter?which of the 2 transverter ends on the cable I use. Again, the XV222 is FB and 432 won?t work.

Some Googling turned up NT4RT who gave a paper at the 2012 SVHFS conference on a bunch of mods for the XV432 to make it work better. Lots of ground via connections, connector rework stuff and loads of changing signal paths by scraping solder mask and cutting traces. All very involved. I have the paper in my Evernote account and will share if you have not seen it, pending NT4RT?s approval.?I?m not sure it he wants it to be ?public?.

My unit has the errata items performed along with an input filter at the TX1 connection described by a DL ham IIRC.

So, here are my questions.

1. Is anyone using their K3 with the XV432 in original as-built condition with good?success? No self oscillation or other issues?
2. What mods did you make to tame the demons, if any?

I?m to the point where I need to decide:

A. Fix this one?which may take A LONG TIME. But that gives me a K3/XV222 and 432 for 6/222/432 in the rear position of my rover with one headphone, one key, yada yada.
B. Ditch the XV432 and use my FT100D as my 6/222/432. This is a pain?because running on 6 and 432 key 222.?I?ve run into problems doing this and it really requires that?the XV222 be turned OFF except when in use. I suppose I could build a switch that would power up the XV222 when?I?ve selected the 28MHz band on the 100D.
C: Build another XV432?and use the current one for spare parts.

Your ideas are greatly welcome.

Mark,

I cannot identify exactly with your problem statement (K3 locks up), but 
I can give you a few suggestions that may help if you are willing to 
experiment a bit.

First of all, you can try putting a low pass filter between the XV432 
and the K3 low power TX output.  The one I use is a Mini-Circuits 
BLP-30+, but any LPF with a cutoff in the 30 to 36 MHz range should work 
just as well (it would not hurt to include in the coax to the other 
transverters as well if the IF cables are daisy-chained).

The purpose is to eliminate any 432 MHz energy from getting back into 
the K3.  Normally the symptoms are only that the transverter TX output 
is 'fooled' into thinking there is 28 MHz power when actually there is 
very little - but your symptoms seem to be more severe.  It may be worth 
a try in any case.

The 2nd is the power output module in the XV432 itself.  That module was 
changed about 6 months (maybe a year, my memory for dates is short).  
The older module was an SAU82L and the new module is E600120 RA30H4047M1 
High Power Module.  The new metal shielded module prevents self 
oscillation as well as having much better linearity than the older module.

My suspicion is that 432 MHz energy is getting back into your K3 and 
causing the difficulties.
Check your XV432 output connector - it *must* be mounted with the flange 
on the outside of the rear panel.  Also check that the paint has been 
removed from all the XV432 panels where they contact the 2D connectors.  
The is important for proper shielding of the XV432.  While that is 
applicable to all the XVxxx series transverters, it is critical for the 
XV432.

Don W3FPR

Good Evening,
     Summer is back here in Oregon after a chilly, wet week.  All the 
plants look well watered and the fire danger is low again. Many of the 
different types of berries are coming into season. This is a good time 
to find a black bear.  Mountain lion sign is around now too.  When I 
walk in the woods I kick up a few grouse, some California quail, and a 
deer now and then.  Hopefully I won't disturb a mountain lion snoozing 
with her cubs.

    Propagation has been up and down but the sun has not been helping 
much.  Some sunspots have come back around after their transit of the 
"back side" of the sun.  Solar flux has been rising for the last few 
days too.  Thirty meters has been open during the afternoon and 
evening.  With the W1AW and DX stations there is a lot of activity on 
that band.

That makes sense and I actually like to run with the house load on 
the gen.  I have a manual transfer switch so I run about 5-minutes to 
allow engine to warm up before applying a load in test runs.  Tend to 
be shorter if there is an actual power outage.

Message-ID: <53D4976A.9030905@tavan.com>

How does the KAT500 decide what Mode to set when it powers up (with or without a K3 connected and running) or when it detects a band change? I ask because several times recently mine has come up in Auto mode which I never use intentionally. I would like a way to "lock it" into Manual mode. Yes, I did BTFM (B = Browse) but if it's in there I missed it.

Subject: [Elecraft] fix toroids in KX3
Message-ID: <1406455844513-7591651.post@n2.nabble.com>

Hello

I saw that on the KX3 and KXPA100 none of the toriods are fixed or glued to
the PCB.
Is there a reason why this was not done by eleraft? Because After some time
the wire will brake if the toroids vibrate especially when transporting the
KX3. Normally they should be fxed. I don't think the inductance will change
much if they will be fixed with a small dop of glue.
Has someone done this already or will elecraft do this in the future?

Hello Keith,

the default setting can be found in the manual auf the KX3. All other 
settings are adjustment-related and not so easily changeable by chance.

You can perform parts of the adjustment by yourself but TXSNUL 
adjustment for example needs a spectrum analyzer.

If the rig is working fine the settings are most likely correct. I would 
reset all values to the known default values and leave the adjustment 
alone or adjust only the parts that you are able of (RXSNUL, TX gain, 
VFO temperature compensation).

Regards!

Sven, DJ2AT

PS: Do not forget to save your new defaults using the KX3 utility!

Elecraft specifically warns that fixatives of any kind not be used on 
toroids.
I don't know if that statement appears in the KX3 or KXPA100 documents, 
but it appears in all manuals where the toroids are wound by the builder.
The toroids are adequately supported by their leads alone.
For one example, I built a K2 for an over-the-road truck driver, and I 
know he used it mobile in his truck for more than 3 years.  No fixatives 
were used on the toroids, and no failures were experienced because of 
the high vibration environment.

As another example, I repair the KX1, K1, and K2 transceivers - they are 
shipped to me by either the postal system or UPS.  In over 1000 repairs, 
I have never found any case where the toroid leads have been broken.

Fixatives are not necessary, and I believe using them in the KX3 or 
KXPA100 will void your warranty.
Many fixatives will change the inductance and Q of the toroids.

For most normal means of transportation this is not an issue.

However, I have experienced this exact failure mode in radios and a
switching-mode AA battery charger while traveling on my motorcycle, which is
certainly a high vibration environment.  I've found that glue from a hot
melt glue gun will provide the needed mechanical support and will not detune
RF circuits.

I have not transported any Elecraft equipment on the bike yet but I do not
see why it would be any different.

You do not need a current menu list to find the default settings - it is 
in the KX3 menu help text.
When in the menu, scroll to any menu item of interest and hold the MENU 
button for about 3 seconds to bring up the help display.  The default 
value (if any) will be shown in parenthesis at the start of the help text.

Thans for the replies and experiences.
I have also seen broken wires on coils (not elecraft) which were not fixed
on the PCB. I was wondering about this when I was assembling the KX3 and
KXPA100.
Most electronic manufactures tighten their coils and even some capacitors
with silicone glue.
I don't think that some glue will affect the magnetic field since most of
the field is anyway inside the toroid.
It may change a bit the capacitance and resonant frequency.
I don't kow if elecraft just skip this extra efford or if there is some good
reason not to do.
I see some of the toroid coils are quite loosy and have small wires compared
to their mass.
Would be good to know if the warranty will be void if I fix at least some of
the coils with a bit of glue.

The KX3 will be covered under the warranty if the toroid wires break - 
*unless* some fixative has been added.
I would suggest waiting until the end of your warranty period before 
doing anything like adding fixatives.

If you want to assess the quality of a generator's output, take a look at
it on the oscilloscope, The cleanest waveforms will come from generators
using a brushless alternator, or perhaps one of the sine-wave inverter
generators like the extremely quiet Honda and Yamaha units.

I know that, at least in the past, Generac used brush type alternators.
These typically had rather dirty waveforms when I scoped them, with THD
well above the 5%  that is considered good. While most appliances are fine
with this higher distortion, a waveform rich in 3rd harmonics makes motors
run hotter/less efficiently. Whether significant harmonics extend into the
RF zone, I don't know - maybe not an issue with our radios. I was able to
find a 6500 watt Porter-Cable unit on wheels with a brushless alternator
which I converted to use natural gas in addition to gasolne if necessary.
This has worked well for me, though now that I have it power failures have
become rare. Go Figure!

Funny thing: I never turn my KAT500 off. I've 
heard funny things can happen if you turn on the 
K3 first and then the KAT500.

BTW -- very good reference to buy is Fred Cady's 
"THE ELECRAFT KPA500 AMPLIFIER AND KAT500 TUNER". 
I have it in pdf form so I can search for it (and 
copy the title for this email, which is why it's 
all caps!).

I ask because several times recently mine has come up in Auto mode which I never use intentionally. I would like a way to "lock it" into Manual mode. Yes, I did BTFM (B = Browse) but if it's in there I missed it.

Yes I agree. But it would be nice if anyone from elecraft could commet why
they see no need for fixing the coils.

Remember that we're talking UDP, not TCP, so it's not actually a connection.

.... and the theory is that IP networks are a mesh, but it often doesn't 
behave like a mesh, and least in any positive way.

Good networks cost more than cheezy ones, but many of us find it hard to 
justify $200+ month.  Level(3) doesn't sell residential DSL.

I'm sure we're about to get shut down by the moderator, but I couldn't 
let this go unquestioned, so I called Generac.  They say that the THD 
spec for their stationary generators is <3%, so they must be using one 
of the better technologies. Mine is a 14KW propane unit with a 
whole-house switch.  It runs automagically every Saturday afternoon for 
about 15 minutes, though with no load.  We've hasd a couple of 
multi-hour outages since we've had it, and I've been on the air on HF, 
and never noticed any noise..

One side topic was ?how long could power be out??

At the Carleton Complex fire in Washington, power is being restored after seven days.

I grew up in Baton Rouge. After Hurricane Betsy in 1965, our phones were out for seven days and power for ten days. We lived in a suburban area in the middle of town.

Subject: [Elecraft] CW using P3, help
Message-ID: <979FC6E3-E23E-45C6-AAB1-C72139FA57E8@frontier.com>

I tried using a keyboard and the P3 in data mode to send CW but it wouldn't put the K3 in transmit. I could receive and decode CW. When I tried to transmit a memory location or via typing I could hear the CW it was trying to send. The P3 displayed TX indicating it was in TX mode. But the K3 was not in transmit.

Looking through the manual it wasn't immediately apparent what I was doing wrong.

Hi Don,

It's a slow summer day so I thought I would throw a keyboard onto my P3/SVGA
and give it a try. It works fine here as long as VOX is showing on the K3
display. QSK can be on or off but VOX must be visible on the K3 display.

And yes, if VOX is off you'll still hear the CW in the K3 monitor. I call
this the code practice mode.

Mike K2MK

Message-ID: <53D547AD.6000705@comcast.net>

Greetings Elecrafters,

On August 9th, the Radio Amateurs of Northern Vermont (RANV) will be 
operating W1AW/1. We are trying to operate from a Hamfest and our picnic 
in the Northern part of the state. We have access to a remote station in 
the southern part of the state, but are missing one important piece of 
the equation. No one here has the Remote Rig for the local side. Since 
this is an operating station, we can not change the other end. The 
remote side is all set up. So, the question is, anyone have one that we 
could use? We are willing to pay any expenses, deposits, etc. that may 
be necessary.  Please reply off list to keep the QRM low.

Gentlemen, 
     If Elecraft has so little trouble then why do it.    After all it might
make repairs more problematic.   I do understand that someone using a KX3 on
a motor bike may have a need but this is not a common application.   

      It is a good question though, so please do not take this as being
critical of it being posed.

Yes I agree. But it would be nice if anyone from elecraft could commet why
they see no need for fixing the coils.

Well after hurricane Sandy I was out for well over a week.   And I'm 50 miles 
inland in the NW corner of NJ.  A big issue was gas. Even gas stations that had 
gas had no power to pump it.

I had an old Dayton with a Briggs & Stratton engine.rated at 2.5kw. Ran fine for 
duration but killer was 25 hour oil  change interval and pull starting.  It like 
many small engines had a "splash" oiling system. Generac has generators at many 
price points.  I settled on an 8KW unit with electric start  but the more 
important feature was a full pressure oiling system with filter and 100 hour 
change intervals.  Just another consideration if looking at generators 
especially smaller ones.

Since purchase it has more testing than generating hours.   I hope it stays that 
way.

So far, the first 14 had nothing to do with anything other than this discussion, or toroids that were damaged by heat because they had power (DC) fed to the output of the radio. ?

Then there was a toroid that was wound incorrectly... in a K2 kit, purchases of cores, ?Antenna discussions of an end fed.... Running power fed to the radio through a toroid, Then a K2 with a problem with drift. And then several involving wall warts that were broadcasting. An older pa making noise (relays).. signalink distortion, and 2 messages about "over the years the toroids used have changed...."

Not a lot of trouble with toroids, I'd say.

Baton Rouge is more than 50 miles inland. Betsy was a big storm, the first billion dollar damage hurricane.

Now I live in earthquake country. Our power outage after the Loma Prieta earthquake (1989) was pretty short, not even a day. 

Interestingly, the Hurricane Watch Net was started by amateur radio volunteers during Hurricane Betsy.

FWIW.

Replenishing gasoline that's been depleted by emergency motor 
generators  may not be as easy as going down to the local Service 
Station.  Most often if you have lost power, so have they, and not 
only will their pumps not work but neither will their cash registers 
or credit card charging systems.  The same may be true at the local 
markets and hardware stores !

I spent a day waiting for a Baja Mexico gas station to be able to 
pump, when they'd lost power.  I had to spend the night, in their 
parking lot, beside my off road motorcycle, that I was touring on .

In the N. CA earthquake of, I believe '85, we were without power at 
home for 10 days.  Fortunately the power company prioritized getting 
power again first to the hospitals and their other commercial customers,

I think that most are looking for something the K3 WRTC numbers are
not telling. I rather doubt that people went out and bought them for
the WRTC.  With those kinds of numbers, the market had already made
its decision a long time ago.

I know some who borrowed K3 and/or P3 for the contest. That means
those skilled operators had other rigs but *wanted* the K3/P3.

The rest (vast majority) already owned them.  In those cases, it's the
rig they bought for themselves, or they had multiple rigs and *wanted*
the K3/P3 for the WRTC.

As a piece of market research, that list should be (and is) terrifying
to other manufacturers. Usually when a single brand/model has such a
huge penetration of top echelon operators, the competition will take
decades to change minds in the market.  The only comparable historical
dominance of this sort is Collins Radio, which eventually lost out to
Yakencom because the Collins transistor offerings were ridiculously
expensive. The Yakencom radio which pushed up market penetration among
contesters was the FT1000MP. Interestingly, among all I know who
do/did have MP's for contesting and upgraded, 90+ percent of those
went to K3's.

As to the technical advantages of the K3, most of my own K3's observed
advantages probably would not show up using the WRTC antenna package.
That is after all an intentional "little pistol" setup. The well known
clean performance of K3's in multi- and close station immunity is very
useful there, but some newer Yakencom are quite good there as well.

If you run a five element 40m wide spaced quad on a 190 foot catenary
trained on Europe, and place an MP side-by-side with a K3, the
enormous difference shows immediately. Even if Yakencom comes out with
an intermediate price unit with somewhat better performance there, The
K3 has a better version of the VHS over Betamax advantage, plus the
huge advantage of the proven, now trusted Elecraft responsiveness to
customer issues. A case can be made that the latter was the biggest K3
competitive advantage.

It should be obvious and without argument that the K3 far and away has
THE market penetration among serious contesters, regardless of how one
might explain it. That is true even without the WRTC numbers, just not
so visible and in-your-face obvious.

73, Guy K2AV

PS, I got my taste for KoolAid as a kid, long before I was interested
in any kind of radios.  The inference that all KoolAid is spiked with
Cyanide is an insult to the memory of my registered nurse mother, who
would do just about anything to keep her kids hydrated out in the hot
New Mexico desert sun, sometimes including her own variety of KoolAid
made from scratch.  Jim Jones was an idiot and ruined a perfectly good
concept.

Elecraft KoolAid (sometimes known as liquid mojo) is good stuff and
perfectly safe for human consumption  :>)

it depends where, as you say?  Here in South Florida, all gas stations are required to have backup power.  Lessons have been learned from our previous encounters with hurricanes and himacanes.

 RemoteRig TX audio?
Message-ID: <alpine.NEB.2.11.1407271545240.3484@chris.i8u.org>

I had a bit of trouble getting my mic audio working initially, but with
Brandon's help it was working. After updating my firmware it's back to
having no audio. I can change MIC SEL to FP and still run the K3
directly, but with it set to rP I don't get any audio at all.

Anyone else have this problem and have a fix? I'll have to call Brandon
tomorrow to figure out what all the steps are to get tx audio working. I
forgot to write them down.

Thanks.

Does your rear panel microphone need bias?  If so do you have the bias 
set ON?

I've tried it both ways, and as I said, I did have it working before the
firmware update. So here's the oddity:

My headset is the Heil that I bought from Elecraft for the K2. It should
NOT need bias as far as I know. I just checked the MIC SEL and when I
have it on FPL, I do have the .bIAS. However, since I thought it didn't
need it, I did change the jumper in the RRC-1258 MkIIs to turn off the
bias. Could that be the problem?

Thanks Don.

The Heil ProSet-K2 (sold by Elecraft) has an electret element, and 
*does* need bias.
Turn Bias on for the rear panel connection and it should work (or set 
the jumper in Remote Rig to provide bias if you are plugging it to the 
RRC box.

Well that was the problem! I wonder why I thought it worked before.

The reason I changed the jumper is because of the RemoteRig users
manual, that says:

 	Control-RRC only: JMP-1 is placed behind the TTL connector. With the
 	strap in place a DC voltage is feed to the microphone element. All
 	ICOM microphones should be DC-feed.
 	Dynamic microphones like the ones used by Kenwood should not be
 	DC-feed. HEIL microphones should not be DC-feed either.

Maybe they just mean the desk microphones.

No, they're incomplete.  Heil dynamic microphones (HC4, HC5,
HC5.1, HC6, "Classic", etc. elements) should not have DC.
*However*, Heil 'iC' elements *must* have DC (bias).

The Heil/Elecraft Proset K2/K3 is the same as the Heil
Proset iC (Icom) - the only difference is the use of the
AD1K (Kenwood adapter) versus the AD1I (Icom adapter).

Be careful with that statement about Heil microphones.  The ones for 
Elecraft and Icom have electret element and need bias.  There is one 
newer Heil element that is electret - I can't recall its designation.
Yes, most Heil microphones are dynamic, but there are many exceptions.
Simply saying the microphone is a "Heil" is insufficient, one must be 
explicit about the exact model and the adapter used.

Well, a certain portion of the market certainly has -- those need a high 
performance rig for use under demanding conditions, including those of a 
contest multi-op.

Egged on by a discussion on another email relector, I replotted ARRL 
test data for key clicks and TX phase noise. I'm not going to stop 
there, but the results so far tell a large part of the story.

k9yc.com/TXNoise.pdf

Consider it a work in progress. ARRL publishes its data in the form of 
graphs pretty small, and in some cases with too-wide ranging scales, so 
it takes a lot of practice to get data within +/- 1.5 dB.

Thank you for the graphs.

This is something the North Carolina PVRC group that did field day
together north of Raleigh already knew about K3's vs. the world from a
pile of experiences.  We had five or six K3's available to us, and we
went purely with the K3's on HF in the 3A class.  We had a little
horizontal physical spread to help out, but we often had both CW and
SSB on the same band at the same time due to the conditions, and one
could not hear the co-band K3.

So I knew what to expect from your curves on the K3.

There were 1-2 Yaesu radios that did not have the after-market key click mod
and were causing tremendous unnecessary QRM to other WRTC stations.  Those
radios were detected in the Friday setup period and swapped out to eliminate
the QRM.

The 65 WRTC sites (only 59 actually used) were spread out over a distance of
80 miles, from the southern NH border to the entrance to Cape Cod in
southern MA.  There were some clusters of sites where 15 or so WRTC stations
were located just a couple thousand yards from each other.  The 100 watt
power limit helped a bit, too.

The one factor that using different radios does not control for is

was when my "neighbor" Jack, KF6T, was running a Yaesu rig with serious 
phase noise problems.  Of course, if clicks and phase noise was an issue 
at WRTC, it would impact everyone else negatively.

I'm partial to the comments below.  While I prefer Win-Test for CW (and SSB)
contesting, I strongly prefer WriteLog for RTTY contesting.  N1MM Logger is
a close second for RTTY.  At the same time, I have to acknowledge that the
current SO HP World Record holder in the CQ WW RTTY Contest used Win-Test.

I believe that the best logger for you is the logger that works best for
you, not the logger that works best for someone else, or is the most popular
logger among contesters.

Only due to two accidents - the large number of European teams and that
WRTC does not include any RTTY component.  When one looks at teams from
the Americas, N1MM Logger was the more popular logger.  When one looks
at the top performers in digital mode contests the results show a much
higher percentage of N1MM logger and WriteLog users.

Win-Test has its pace if one is stuck on a user interface from the last
century and is only concerned for CW (not that either is necessarily
bad).

Thank you. Very persuading comparison.
Could you possibly add some modern SDR based rigs to the comparison?

I agree completely. And the logger that is best for you is usually the 
one that you know so intimately that everything is completely 
instinctive. That takes lots of operating time!

Because I'm happy with N1MM, and because it doesn't do CQP, I haven't 
bothered to study WinTest. I'd be interested to hear from WinTest users 
what they view as its advantages. The only things I've heard so far is 
that networking is quite solid and that the UI is very much like one of 
the popular DOS programs.

Hello Igor,

So far, I've not bothered to look at the older ones, having read this 
work, and ARRL has not reviewed anything since the Flex 3000 in 2009.  
For that one, keying looks like the middle of "middle of the pack" rigs, 
phase noise is about -120 dBC all the way out to 1 MHz.

http://sm5bsz.com/dynrange/dubus313.pdf

I've seen predictions that the newer rigs will be better.

Hi Jim - will you be adding the spectral display graphs of "transmitter 
composite noise testing"  which appear in the various product reviews to 
your summary?

If so, I will help mine the graphs from the reviews, if that will ease 
some of the work load.   I know that takes serious time.

So far I don't plan to -- they don't add much to the analysis. I showed 
the keying spectra simply because many were so radially different, and 
that it might give thoughtful designers clues as to the reason. Perhaps 
IMD with the click modulation?

Perhaps this is discussed somewhere in the thread, but I am surprised by the
lack of Flex SDRs in the mix.  I would have thought at least a few would be
there for PR, if no other reason.

All,

Noticed this when using skimmer and reporting spots to the RBN.? When I have a strong station reported I will also spot a copy of that station weaker and some 16 to 18 khz higher on the band.

Is there a solution to eliminate the false weaker image?

The West Valley Amateur Radio Association operating as K6EI and 
W6ZZZ (GotA) had a similar experience. We operated 6AB-QRP with 
CW, SSB and digital HF stations. We used K3s and KX3s 
exclusively. Our antennas were arranged in a line to minimize 
interference. We would often have CW, digital, and SSB on the 
same band. In operating the digital station, I never noticed the 
CW people. The only way I noticed the SSB people was by 
overhearing their sound waves from the tent next door. :-)

hello

With the antenna disconnected, I have noticed some very weak "birdies" 
on most of the bands, with a 15 khz separation; most of them are below 
the noise band level with a connected antenna; I made the test in a 
remote place in the deep vcountryside in souith west of france, with a 
KX3 poxered by battery ; natural or artificial noise level is very low.

but

these birdies disapear completely when the LED BRIGHTNESS COMMAND is set 
to 1, and reapear when the command is set higher than 1.

Has somebody else noticed the same bahaviour ?

best regards es 73

There is an article that addresses the earlier Flex products, which 
shows the Flex 1500 and Flex 3000 to be... well... kinda punk in the 
noise department.


http://sm5bsz.com/dynrange/dubus313.pdf


No doubt it would be swell if all radios could be included, but I 
believe this is a HUGE time consuming job mining data by sifting through 
all those old reviews and selecting the correct data, and then even more 
time to plot them in a consistent manner.

I am not sure there is data on all rigs of interest, and the newest Flex 
radios revealed at Dayton have yet to be reviewed, heck it takes 8 to 9 
months for a new rig to get reviewed in QST magazine.  It takes time to 
test, and issue content is lined up months in advance.  I had a piece 
published in the Nov 2013 QST magazine, but it has been submitted 11 
months earlier.

Chris,

My guess is that you are hearing a low level digital noise (rather than 
birdies) coming from the MCU as it illuminates the LEDs.  The fact that 
they disappear when you turn the LED brightness down leads me to that 
conclusion.

PR?  What's that?

The K3 and KX3 are both SDRs with knobs. I'm guessing that you mean SDRs 
without knobs.

My interest is primarily contesting, the subject was radios for 
contesting, and rigs like the Flex products have made little headway in 
the contesting community.  I know of only two guys contesting with Flex 
radios . One is K6TU, and the other is K6XN, who bought K6TU's older SDR 
that is new model replaced. No, I don't remember which models were 
involved.

However, several guys asked, so I've added all three SDRs that ARRL has 
tested to the plots.  I've also corrected a labeling error on one of the 
plots, added a plot of phase noise for a 500 Hz bandwidth, and added 
some text.  It's all still at k9yc.com/TXNoise.pdf  I suspect that these 
plots will make it clear why contesters aren't thrilled with these radios.

By all means, before you consider one of the Flex radios, be sure to 
study this work by Leif Asbrink, SM5BSZ.

Hello Sam in Ole Angelo,

The distortion you are noticing is very real and has bothered me to no 
end. It is discussed on a couple of websites, that I am sure the 
"experts" will jump in and tell you all about.

I did some research on the subject and a lot of experimentation. I 
eventually found the distortion can be reduced (or enhanced if you like 
being annoyed) by changing the menu values of AGC SLP. I have mine set 
at 6 and it makes the warble of the ANF (Automatic Notch Filter) - far 
less than the 12 default setting. Some of my other menu settings (for 
the arm chair copy user) can be found at: http://www.w2blc.net/K3.htm

I am sure others can expound upon the whys and wherefores of the 
software anomaly that causes this annoyance. Suffice to say, invoking 
the ANF on my other rigs does not cause distortion on received signals.

As always, your mileage may vary.

Bill W2BLC K-Line

hard to describe, it's like the audio is getting chopped up, not sure 
this would explain it, but it's kind of like the sound of someone 
gargling being overlayed over the  signal audio. A combination of that 
and the sound of NR @ 5-1.

if the band is very quiet and the signals strong it's very pronounced, 
if the band is noisy it's not as pronounced

I have found if i am trying to remove Cw i can use manual notch set to the
signal and it seems the distortion fades away.
I gave up using both auto-notch and NR on the k3

At time like this I appreciate having 
"non-critical" hearing capability (deaf in one 
ear, ringing in both). My K3 sounds great under 
all conditions -- and no fan I have makes any 
noise :-)

what you hear is a fast time constant on the auto notch.  The
faster time constant makes the notch respond faster but it also
allows it to attack "purer" tones in the audio.  The effect is
more noticeable on strong signals with flat AGC curves where
all frequencies in the audio passband are of similar levels.

The effect is a result of the design decisions made by the DSP
programmer - a tradeoff between notch effectiveness and fidelity.

Hi all,
I have a KX3 with ATU and a KXPA100 with ATU (an overkill, I know, but I didn't buy them together and they are for operating separately in the field).  I would like hook both the KXPA100 and my K3 to the KAT500 in the shack through a coaxial switch, but I can't get the new KXPA100 to play well with the KAT500.  The amp keeps changing from bypass to auto and sometimes the atu in the KX3 also kicks out of bypass.  The rig and amp/atu work fine connected directly to the antenna.

I am still learning with the new amp, but if anyone has suggestions they are welcome.

Whenever you want to use the KPA500, make sure you set the KX3 menu item PA Mode to OFF. You can assign this menu item to one of the PF function keys for convenience.

The amp keeps changing from bypass to auto and sometimes the atu in the KX3 also kicks out of bypass.  The rig and amp/atu work fine connected directly to the antenna.

Subject: [Elecraft] KX3 - selfprogramming macros - why does PF1 work ok,
	but not PF2
Message-ID: <53D7490A.3060801@arrl.net>

I have made a macro assigned to PF1 which sets the KX3 in split mode 
with subrx. The macro is followed by some commands which reprograms PF1 
to remove the split and revert to single RX by setting PF1 to macro 2 - 
this works fine and allows PF1 to both turn on and turn off split. Macro 
2 does the reverse and reassigns macro 1 to PF1 - thus PF1 works as a 
toggle between split+sub rx and no split.

For PF2 I am trying to make a similar setup to allow two macros on the 
same button, the critical commands are;

To reprogram to macro no 4 (just the reprogram steps shown): MN110; 
SWT28; SWH26; MN255;
Or said differently; enter macro x, tap 4, hold PF2, exit
To reprogram back to macro 3: MN110; SWT20; SWH26; MN255; (enter macro 
x, tap 3, hold PF2 and exit)

For some reason I am not able to make this work on PF2, the same 
sequence works fine on PF1 but I am not able to make it work on PF2. I 
have similar commands on my K3 and they works on all programmable buttons.

Can anyone spot an error in my logic or have I met a bug in the KX3 
firmware?

But are you seeing that packet loss reflected on every hop past that point? ISP routers are often configured to rate-limit or block responses to ping and traceroute requests since both require the router to actually process the packet with their CPU rather than simply forward the packets which is done via specialized hardware ASICs. If you see packet loss at one hop but you don?t see similar packet loss on every hop from that hop on, chances are you?re running into rate limiting or blocking and it?s not impacting your actual packet forwarding.

This is also a reason why Lynn?s suggestion to pick a local ISP router may work they way you?d want either.

I was a WRTC 2014 volunteer responsible for overseeing 4 different stations. 
Of the 8 radios at these stations, 6 were K3s.  Before the contest started,
we did have a significant issue with phase noise interference from one of
the K3s on 15M when that station was beaming toward the adjacent station
(also receiving on a K3).  The interference made 15M unusable at the
adjacent station.  When we tested with the non-K3 from the same location
with the same beam heading, the phase noise was not a significant problem.
If we reduced the K3 output to 30 watts, there was no problem. Fortunately,
we were able to change out the original K3 with another K3 and that
significantly reduced the problem.

I have used my K3 at a 160M multi-op station and recognzie how important it
is to properly set up the AGC parameters to allow two radios to be on the
same band.  Since we were able to resolve the problem to the competitors
satisfaction, I didn't probe any further into the setting of the K3s.

Gerry, W1GD

Hi,The first thing you will want to do is to reset the equalizer to 0 for all bands. Command:?MN008;SWT53;MN255;
Next you issue the following:
MN008; which selects the equalizer menu, then you issue the equivalent of a tap on a button for the particular equalizer band you want. So for the 50hz band in the equalizer you would normally press the "1" button which is a SWT11; then you issue as many UP; or DN; commands you need.
So to raise the 50kHz equalizer by +5 you would do the following
MN008;SWT53;MN255;
MN008;SWT11;UP;UP;UP;UP;UP;


For the other bands in the equalizer you can look up the SWT table in the programmers reference for the buttons 1,2,3,4,...etc.
Note: Issuing many UP; commands without delays, will not necessarily always work for the equalizer.

I'm not going to disagree with Bob, he's right, I've just not seen pings 
and traceroute limited on internal routers very often, mostly on routers 
at the edge of an ISPs network.

What's between Hop #1 and Hop #2?  A wire that is unique to Chuck's 
connection -- the wire from him to his ISP (and "wire" could be cable).

This is a great example of why I said don't ping something too far away: 
if that wire is a little bit flaky, it'll show a lot of packet loss.

No wire has a zero error rate, so an occasional dropped packet is no big 
deal, but if it's more than about 1% I'd be concerned.

It would cause problems because some calibration parameters individual 
to each radio would be copied. So don't try to trick it into letting you 
do it!

No, it is not possible to copy configurations from one K3 to another. In my view, bypassing the serial number check would not be straightforward (I would guess that Elecraft use checksums to protect the integrity of the files). If you somehow manage to achieve this, then yes, it will cause problems with the target radio, and the radio would need to be recalibrated.

Hi Gerry,

Thanks for the info. As the ARRL data shows, phase noise performance of 
the K3 that's working right is quite a bit better than any other modern 
rigs out to 1 MHz, but that's as far as ARRL's published data goes. If 
it was my K3, it would have gone back to Elecraft as soon as I could get 
it there after the contest, even handing to them in their booth. :)

Message-ID: <53D7CD58.1080908@ntlworld.com>

Yes I know the RF to RF board or ATU connector doesn't turn (much!) as 
the chassis hole is keyed but after about 2 years use attaching and 
disconnecting bnc there must have been some movement as on EU037 Garpen 
as SM7/M1KTA/P over the w/e I was getting odd  RF drop outs/ vswr all 
over the place etc (using #1082). Now I travel with a spare KX3 for DX 
and contest so swapped out the KX3 (spare #2334) and carried on (RSGB 
IOTA contest) after contest had a look and put it down to the RF lead... 
the repeat use of connections that apply even a slight rotation to the 
radio had fractured the lead from the centre pin of the BNC to the 
flying lead. Visibly it looked fine but the only thing that was keeping 
it in place was the little bit of black shrink wrap. At first thought 
was the BNC centre pin but it wasn't as worked fine with the other 
radio. Cut the shrink wrap back a bit and the lead had separated from 
the socket at the place where the solder started, it literally fell out 
..... culprit found.

Now back home I'll remake the RF connector. Using a piece of RG316 or 
RG174 with a little strain relief loop. Yes the space is tight!

My #1082 is about 2 years old and it has seen a lot of use/abuse I will 
admit.

Anyone else had a similar issue?

Message-ID: <7748EFF8-7042-4F78-8B11-729420308A2D@mac.com>

Greetings Elecrafters,

I?m new to the K3 (and HF in general), and I?m trying to sort out how to get useful results from the Noise Blanking (NB) features.

I?m looking for strategies, tips, techniques, etc. for selecting the settings for NB. With over 14,000 possible settings between the IF NB and the DSP NB (according to KE7X?s K3 book), I find myself getting overwhelmed and I give up on NB. Honestly, I can hear very little difference as I go through the various NB settings, so how am I suppose to choose the ?right? one?

I operate SSB almost exclusively, and I don?t use all-mode squelch  - but I need to experiment with this. I?d appreciate hearing your take on squelch.

What?s your secret recipe for picking NB settings that work?

Thanks!

The memory editor (for KX3/K3) is the best compromise.  Ops may use it
to transfer memories from one unit to another.  This program does not
change configuration, just memories.

As Matt said, transferring the entire config from one unit to another
would change the target's parametrics and might make it unusable,
requiring recalibration.  The config section of the K3 and KX3
utilities registers the serial number and a CRC (checksum), and the
config image may only be restored to the original radio.

Think it might be worth-while to have an 'exportable config' option in the
utility that just copies over Tx/Rx eq, Norm I/II configs, NB/NR settings,
macros, DVR data, saved frequences, etc?  That way you can sit down at
someones K3, upload your user-config, and have 'your' K3 with things set
how you like it.

Will be good to have a set of parameters of personal configurations that
don?t affect calibrations or something else and can be copied from one to
another K3

I think that could be done with some parameters, right?

It would cause problems because some calibration parameters individual to
each radio would be copied. So don't try to trick it into letting you do it!

As no one has responded yet, I'll throw in my most recent experience:

I assume you meant to say Noise Reduction - a mistake I made a couple of 
months ago. Although I was quickly informed of my mistake, I never did 
receive any really useful information regarding the many settings 
available on the K3.

My specific question involved thunderstorm static - for which the K3 is 
no better than any other rig. In fact, it handles the noise less well 
than a couple of my other rigs. Hence, I do not use the K3 during high 
static conditions.

Be aware that many answers will be sent to you via direct email, rather 
than on this reflector. Should one of them be informative, please post 
same - in order that we may all learn.

Hi
Win4K3Suite starting in version 1.62 has the ability to export and load most menu settings to a file as well as the current operating parameters.  It does not transfer any serial number related settings.
You can see an example at
 http://va2fsq.com/?page_id=612
about 1/2 way down the page.
The export allows you to export the current settings of the menu commands you see as well as the current state of the K3 or KX3.
Memory frequency files are separate as are macros.
Of coarse with enough demand this can be enhanced .

Please forgive this off-topic post - I?m hoping some of your can provide some info.
I?m about to take part in an International camp for Guides and Scouts in the UK, we will have 7000+ participants from all over the world. My bit is try to present emergency radio communications to groups that will visit our special event station (GB4WGS) throughout the week - by the end of 5 days, we should have been able to talk to all 7000!

I and a number of other amateurs want to get across to these youngster that mobile phones etc. aren?t always the means of communicating and to explain how valuable amateur radio is when you need it.

I?m looking for information about recent disasters attended and help my the amateur radio community.

I thought there would be a lot of facts and photos for Haiti earthquake, Boxing Day Tsunami and hurricane Katrina etc. on the Internet, but don?t seem to be able to find much. Things like the number of operators who worked after the disasters, how long for etc.

Anything you could send in the next couple of days would be of great help. Any personal stories you?re willing for me to share etc?
If it involves a K3, even better.

Please don?t clutter the reflector with lots of mail - send direct to me please. I?ll try to acknowledge everything, but if I get a lot (I hope I do), it may take a couple of weeks before I can get back to you all.

You better make sure you have a reliable ALC connection in there somewhere 
because you'll smoke the PW-1 if you hit it with a hundred watts.  They 
normally take about 35 -45 watts drive for full output.

Why not try driving the PW-1 directly with the KX3?  I did and it works 
fine.  I don't get a KW out, but it's quite respectable power out with 12 
watts drive.

Hi Arlen  -  I, too, seek just such a general guide for using the 
various noise reduction features on modern transceivers, but have yet to 
find one.  Transceiver user manuals are typically pretty lean on real 
world explanation - they enumerate the features, point out what button 
or knob makes an adjustment, but there is a paucity of explanation on 
how and when to use those features on the air.  This is a problem with 
many other features on these radios.  Moreover, the manuals rarely 
explain how an one feature relates to the another noise reducing 
features, including the NB Noise Blanker, BW Bandwidth, PBT Pass band, 
RF-Gain, and other controls, which, when used together, work pretty well.

Modern transceivers like the K3 have different tools for different 
problems.  I recommend a detailed web search for articles and comments 
that explain how these various systems work, in general, and which work 
best on what types of noise, in particular.  Eventually, you will 
assemble enough information to better understand how these features 
operate and interact.  I have yet to find a single, comprehensive 
explanation in real world terms... and I have looked!

Sometimes a combination of adjustments will get the click.  Sometimes 
nothings gets the click.  This research will pay dividends and you will 
learn about the K3 and other radios as well.

In any case, there are no free lunches, these tools alter incoming 
signals, causing, in turn, some level of distortion and impose unwanted 
digital "artifacts" - hopefully resulting in greater intelligibility, 
but with some fallout or deleterious impact in the signal.  You trade 
off one for the other, and hopefully don't go too far and make things 
worse, which is easy to do.  Used in moderation, audio quality is 
sacrificed to some degree to achieve better intelligibility.

The first thing you must determine is which type of noise is tackled by 
each noise reducing feature.  For example, and it varies from rig to 
rig, but generally (speaking in very general and not scientific terms 
lest I generalize too much) -  DSP NR attempts to reduce random noise 
like atmospheric static and general hiss which covers a weak signal. The 
NB Noise Blanker typically reduces repetitive pulse type noise like 
ignition sparking, and some NB circuits are geared more to reducing the 
heavier pulsing of radar systems, like what SW listeners call the 
Russian Woodpecker.   The AN or Auto Notch seeks out and removes one or 
more constant tones, like when someone is tuning his antenna tuner right 
over your QSO.  A manual notch does that manually, you gotta adjust it 
out, frequency and bandwidth are user selected.  The PBT or Pass band 
Tuning control allows you to shift the receiver pass band left of right 
to avoid a problem signal on one or the other side of the signal you 
want.  You get less of the desired signal, but maybe none or far less of 
the offending signal that way.   RF-Gain can often be used to lower 
signal and noise (so to speak) and you end up with less noise and less 
signal, but maybe a better signal-to-noise ratio where noise is less 
noticeable against the resulting signal volume.

You should research how each one works, on transceivers generally, and 
the K3 in particular, and EXPERIMENT with each individually and blended 
with others for best advantage, each situation may vary from another in 
some way.

There are few concise explanations, so it may take some time to assemble 
a comprehensive explanation, but the effort will pay dividends on your 
time investment.

Good luck.

Subject: [Elecraft] K3/Mini 0
Message-ID: <53D809A7.6060602@gmail.com>

Got my new K3 Mini 0 today.  Since I didn't order the cable, I made one 
to take the
DB15 to the TTL only.  I'm using existing cables that I had already made 
to connect the Remote
Rig box to a keyer, microphone, and PTT footswitch, and the Mini works 
fine with my
Remote station.

When it arrived, I checked and I thought it was on firmware 4.83, which 
means I needed
to upgrade the firmware but I'm not sure how to connect the Mini to the
computer to get the upgrade.  I tried the USB cable, and it created two 
comports, but the
K3 Utility doesn't see the Mini when I attempt to use either of the 
Comports.  I had already
hooked up an RS232 cable to the Remote Rig Control box at Com1, and N1MM 
Logger
software is happily communicating with the Mini, but again, the K3 
Utility 1.13.5.9 doesn't
see the Mini using that comport.  I know the firmware updating 
recommendation is not to do
it through another piece of equipment, but if the K3 Utility doesn't 
even see the Mini its not
an option.  So, how do I update the firmware?  Since I went through 
this, I unplugged the
TTL cable from the RR box, and now the Mini shows me the actual firmware 
that it has
installed is 4.86, so no upgrade is currently needed, but I will 
probably need to update it
sometime in the future.

I was quite disappointed in the manual, particularly in what it didn't 
cover.  I already have a
working remote station, so I don't need all the diagrams that show how 
to hook up a
remote station using the RR boxes.  I do need more information on the 
Mini itself.
On the left side there are 3.5mm connectors for Spkrs and Mic; are those 
stereo or mono
jacks?  The Mic connector- would that be selectable in the firmware as 
the RPL, and the
front 8-pin connector the FPL?

On the right side, we have the USB port and the DC in.  Both 
self-explanatory, given that
cables are supplied for those two.

On the back, we have key, paddle, and ptt jacks.  Are these stereo or 
mono jacks?  If I had
the cabling from the DB 15 to the Aux/Mic and the I/O inputs on the 
Remote Rig, could I
then connect the computer keying to key, my paddle to paddle, and a 
footswitch to the PTT,
and the connections would then be passed on to the Remote Rig box?

Is there any way to CW key the Mini by sending CW on the DTR line and 
PTT on the RTS
line, via N1MM?  I've played with this for a little while, but haven't 
found a solution yet.

Thanks for assistance with any of the above matters.

I'll try.  The short answer, in case you're not into an explanation is:
"It all depends on your circumstances, the character of your noise, the 
strength of the signal you're trying to copy, how much distortion you're 
willing to tolerate ... and sometimes the phase of the moon."  No one 
can give someone else a set of numbers that will work in every case.

The K3 has two Noise Blankers and a DSP Noise Reduction feature.

Noise blankers do exactly what their name implies ... when a sharp noise 
pulse comes along, they simply punch a hole in the signal [mute the 
receiver] for a short period.  The adjustable things are generally the 
length of the "hole" and some form of threshold setting that determines 
when it decides it's a noise pulse.

The K3 has one hardware NB at the 1st IF [8 MHz] that works essentially 
like any other NB.  It also has one in the DSP firmware that operates on 
the "number soup" from the ADC.  It too blanks the signal for variable 
times and under variable conditions ... because it's doing it with 
arithmetic and not hardware components, it can be somewhat more precise.

Noise blankers are effective against repetitive short pulse noise such 
as ignition noise from a vehicle [not nearly as common as 40 years ago] 
and precipitation static.  They are *not* very effective against power 
line hash although sometimes they'll knock it down some if it has a 
short repetitive component.  They are not effective against T-storm 
static much at all.

Obviously, punching holes in the signal distorts it and the longer the 
holes, the more distortion.  As you increase the aggressiveness of the 
NB, you'll start trading noise for distortion, so the basic rule is, use 
as little as possible.  They're not magic.

Noise Reduction on the other hand all happens in the DSP.  There are 
various approaches to it, in the K3, the DSP algorithm builds a variable 
filter on the fly to enhance the desired signal, thus appearing to lower 
the noise.  How well it works depends on it's ability to identify the 
signal components separate from the noise.  I have found it to be much 
more effective on SSB than CW with very narrow bandpass.  I rarely 
operate SSB so mine doesn't get much use.

The "aggressiveness" of the NR is adjustable in the K3.  The first half 
of the available settings operate on the signal and what you hear is the 
result.  The second half mix in some non-NR'd signal with the output. 
The general rule for NB [as little as necessary] sort of applies to NR 
too, and again, no one can tell you exactly how to use it.  That's a lot 
of words to say, "NR isn't magic either."

Subject: Re: [Elecraft] K3 - noise reduction query 

There is an incredible range of characteristics to unwanted "signals" 
that we loosely call noise.

The K3 has an array of tools to fight noise, and sometimes they work 
well in concert and sometimes better alone.

There is an IF blanker with adjustable threshold and pulse width - but 
some impulse noise ay wider than the widest available setting and this 
is likely to include lightning-based pulses.

There is also a DSP-based "IF" noise blanker.

There is a noise reduction, or denoiser function available with a wide 
range of settings.

AGC settings can also affect the operation, and apparent effectiveness, 
of the DSP-based noise reduction and to some degree the noise blanker.  
There is a pulse function in the AGC system that you can enable or disable,

These settings may all interact to some degree.

As the station operator, you have a complete communications system to 
manage: antenna, feedline, QTH, desired path, time of day and so forth.  
The radio is one component of the system.  The K3 offers a range of 
tools for you to use, but in the end there is unlikely to be a "magic" 
setting that works for everything. If there were, we would have set that 
at the factory for you (and probably removed the settable "knobs" for 
you to adjust)!

I suggest that if you are having a severe noise problem, you experiment 
with the various settings - including AGC threshold and slope and PRE 
and ATT settings as part of the tool set - and note which work best for 
you in your system and under which types of noise and mode(s) of operation.

You won't hurt anything, and you may learn a lot.

And, yes, some radios may work better than others with some types of 
noise under some circumstances.

Just to clarify... use of ALC with the PW-1 is not to adjust drive 
power. That's a bad practice. You MUST use the ALC line because the amp 
uses this as a primary means of protection. Without ALC, a fault 
condition can damage the amp.

Josh,

If one insists on using ALC for amplifier protection, set the level well 
above that which will cause ALC to reduce the driving transceiver's 
power during normal operation.

Most well designed amplifiers provide adequate self protection and 
should not rely on ALC to reduce the drive in the case of a fault. If 
the amplifier design relies soly on the use of ALC to provide fault 
protections, I would call that 'risky design'.  If it is the primary 
means of protection, that is an example of poor design IMHO.  To rely on 
an external device for such protection is to rely on a device that also 
is subject to failure - in other words, poor design IMHO.

Well, yes it is when connected to an Icom transceiver it is used precisely 
to control drive power.

I have the PW-1 connected as recommended in it's manual to an IC-7600.  My 
output control is set for about a hundred watts barefoot and 1 kW when the 
amp in enabled.   The output power when driving the PW-1 is far less than 
100 watts and the only thing controlling the drive is the ALC line.

Besides, I thought that's exactly what I said.....

The proverbial fly in the ointment is that the I don't believe the KX3 HAS 
and ALC input.

Sorry, my error. You CAN use ALC to control drive power, but it should 
not be used for that purpose. If you set the transceiver to 100W and let 
ALC reduce it during normal operation, you generate trash in your 
transmitted signal.

Prior to replacing my Icom transceiver with the K3, a neighbor 
complained that I had bad key clicks. Turning down drive power on the 
transceiver, rather than relying on ALC, substantially improved my 
signal. This was using a PW-1.

PW-1 uses ALC for protection. Unless I misunderstand, running the PW-1 
without ALC, even directly from a KX3, may not be a long term reliable 
solution.

Hi Dennis,
 
I have my K3/0 Mini for 3 months. I spent one month to successfully configure K3, K3/0 Mini, N1MM and DXLab.
 In order for you to update the firmware, disconnect the RRC cable from your K3/0-MINI. Connect your      K3/0-MINI's USB cable to your PC. Open the K3 Utility. K3 Utility should find your K3/0 Mini. My K3 Utility is the same version as yours. Paddle jack is stereo. I am not sure if key and PTT jacks are stereo or not. I am using stereo plugs for them and tip and sleeve do the job. With cabling from the DB 15 to the Aux/Mic and the I/O inputs on the Remote Rig connected, you can connect the computer keying to key, your paddle to paddle, and a footswitch to the PTT. That is exactly what I configured. I have N1MM installed in my local PC, which is connected to my local RRC-1258 via a USB cable. In this configuration, N1MM can CW key the Mini by sending CW on the DTR line. Just like a normal setup of N1MM. I do not use RTS as PTT since I use QSK. When I first got my K3/0 Mini and RRC-1258, I found your posting about the configuration at Remoterig forum. That was very much informative for me. Thank you very much. Hope it helps.

Just  thought I would pass along my recent experience on the KX3 Yahoo Group. 
Yesterday I received a heatsink from KB8UHN.  I posted on the KX3 Yahoo
Group that I received a heatsink from KB8UHN and it was a quality product
and about half the price of other heatsinks.

About an hour later I get an email from the moderator telling me I'm banned
from group for promoting products.  I replied "Sorry did not know your
rules, you would think a warning? He did not respond to my query.  

Johnny Siu VR2XMC told me he has been banned from posting on the group for
agreeing with my post about the heatsink.

So be careful on the KX3 Yahoo Group.  Somehow I will suffer through this
traumatic banning.

Fred has given you a great explanation and excellent advice. I'll add a 
bit of clarification. A Noise Blanker does NOT do much (if anything) on 
broadband random noise. Rather, it works mostly on various forms of 
man-made noise. Much of the noise I hear comes and goes, and/or is 
different on different bands.

As Fred has made clear, less is more -- when I use the NB, I often do a 
long push on the knob to enter setup mode, and reset both the DSP and 
the IF to those best compromise minimum values that reduce the noise 
without chopping too much of the audio.

It also helps to RTFM, which has some advice about what the DSP NB does 
and what the IF NB does.

When you change a NB/NR setting, don't expect a instantaneous change.
Count to five and then conclude whether a setting change helped or not.

In some past posting, this was pointed out by Elecraft.

Subject: [Elecraft] KX3 + JT9 -- any successes?
Message-ID: <53D91639.80306@aa6e.net>

Hello, all,

I've been working with my stock KX3 and HF JT65 / JT9 via the WSJT-X program.  Brief 
results:

--Mostly bad luck with JT modes until I did the "Extended VFO Temperature 
Compensation Procedure".
--After doing the procedure, I can work JT65 pretty reliably for P ~ < 3 W.
--I can decode JT9 sometimes, but I can't get anyone to decode my transmissions.  (20M)

The result of the temperature calibration was that I seemed to have +/- 1 Hz 
stability (compensation?) at 50 MHz from 22 to 55 C.  I thought that was pretty good, 
but it still does not seem to give good JT9 results.  (JT9 is extremely narrow-band 
with 9 tones spaced at 1.7 Hz across ~15 Hz of bandwidth.)

I have seen what some folks have done with larger heat spreaders and heat sinks, and 
even cooling fans.  Has anyone tried liquid cooling? (Just kidding!)

My question is whether any of these strategies have resulted in reliable operation 
for JT9 -- or should I just scratch that mode off my list? (I do have good experience 
with this software and JT9 on the Ten-Tec Orion.)

I'm not complaining.  Nobody promised the KX3 was good for EME -- or VLF datacom!  It 
is a shame that there's not better thermal isolation for the reference oscillator.  I 
think Elecraft meets its own (vague - what time scale, what environmental 
conditions?) +/-1 ppm "typical" spec, but the problem is that we need better 
stability than that over a 1-minute transmission cycle  -- .05 ppm or even .01 ppm.  
A typical TCXO like the Orion's will do that, since the oscillator is thermally well 
separated from the PA heat sink.

TIA / 73

I've successfully made a few JT9  QSOs on 6M with my K3, and get good 
copy on other JT9 signals that I know are coming from K3s. But K1JT 
advises against using JT9 on VHF (and urges caution even about 10M) 
because of its sensitivity to frequency drift. Quoting from his post 
today on the WSJT reflector,

=   =   =   =   =

"It's hardly accidental that the docs explain that JT9 was designed for
the LF, MF, and HF bands.  Even 10 m is s stretch, with some radios and
some propagation conditions.

"Like JT65, the JT9 decoder does have an AFC as part of its bag of
tricks.  It's always engaged, solving for a linear frequency drift term
before decoding is attempted.  The algorithm can perhaps be improved.
It's a tougher job with JT9 than with JT65 -- not least, because the JT9
protocol devotes only about half as much time to a synchronizing tone,
compared with JT65."

It is good that you are not complaining, but I just don't *get* it.
The specification is for +/- 1ppm over a temperature range of 0 to 50 degC.
You say the mode being tried needs .05 ppm or even .01 ppm.  Why would 
anyone attempt to use a radio for that mode for which the specification 
is worse than the needed stability by a margin of 20 to 100 times?
One might expect success with a factor of 2, or even 5, but to expect 
success with an instrument that is 20 to 100 times less frequency stable 
than required just makes me shake my head.

Compare it to trying to make a measurement in the low millivolt range 
using a voltmeter only good to 0.1 volt.

Just  thought I would pass along my recent experience on the KX3 Yahoo 
Group.
Yesterday I received a heatsink from KB8UHN.  I posted on the KX3 Yahoo
Group that I received a heatsink from KB8UHN and it was a quality product
and about half the price of other heatsinks.

About an hour later I get an email from the moderator telling me I'm banned
from group for promoting products.  I replied "Sorry did not know your
rules, you would think a warning? He did not respond to my query.

Johnny Siu VR2XMC told me he has been banned from posting on the group for
agreeing with my post about the heatsink.

So be careful on the KX3 Yahoo Group.  Somehow I will suffer through this
traumatic banning.

Is the Yahoo! Group an official Elecraft function?

I don't believe it is, which is one reason I choose to stay clear.

Nick,

None of the Yahoo groups are Elecraft owned, controlled or moderated.
Likewise for the Nabble representation of the Elecraft reflector.

The only official Elecraft reflector is the one at mailman.qth.net.
It is owned, controlled, and moderated by Eric at Elecraft.

Message-ID: <1406746857211-7591766.post@n2.nabble.com>

So I sold my K1 about 3 months ago to buy another K1 to build.
Not that I didn't like my K1 I just wanted to build.

Now I find out the K1 4 bander is not available and I really have to 
wonder if $550 for a 2 band QRP rig is a wise choice.

Of course I'm not asking you to MAKE my decision for me.  I just was
hoping to bounce it off other people who actually know and care about
this kind of stuff.   My only true ham friends (all 2 of them) think I'm
crazy even contemplating the K1.

Other choices:
 1.  Elecraft KX1
 2.  Oak Hills research OH100A
 3.  KD1JV tri-bander

Just typing this up I'm thinking the K1 is a good choice.  I plan on
building
the KX1 in the winter.... if they keep making them.

Thanks for listening

The K1-2 is $299.95.  You must be considering another $250 worth of
options.  When I built mine, the only option I ordered was the LCD

Go for the Gusto!  The K2 is a much more versatile unit, and a ton  of 
fun to build.   And, you actually get to build it, instead of just 
assembling a box full of sub-assemblies.   It also lets you repeatedly 
exercise your inner demon by building useful add-ons one at a time.

Hi all:

I am recovering from a lightning event at W3BW on Maryland's Eastern Shore.
 I have lost 3 PolyPhaser 1S-RCT.  These units have become hard to find and
incredibly more expenseive than in 1999 when my tower went up.  I have
decided to try using an Array Solutions ASD-16SP which protects 16 lines.

All of that is a lead-in to my question.  The mounting approach for the
AS-16SP is different from that for the PolyPhasers.  i need to find some
thick copper sheet that I can bend to fabricate the mounting I need.

Can anyone recommend a supplier for copper sheet --- maybe 1/8" to 3/16"
thick --- and available in sizes of about 1ft. by 4" or bigger?

Thanks.  BTW, The PolyPhasers protected all my remote relay lines --- those
relays are cheap and in the base of the tower.  I did not get the same
protection for the rotor lines --- lost my Orion rotor --- expensive and at
the top of the tower.  Oh well....

Hi all:

Can anyone recommend a supplier for copper sheet --- maybe 1/8" to 3/16"
thick --- and available in sizes of about 1ft. by 4" or bigger?

Thanks.? BTW, The PolyPhasers protected all my remote relay lines --- those
relays are cheap and in the base of the tower.? I did not get the same

Fred:

I wrote a couple of K3 macros to test the technique:

To set all Rx EQ flat:

MN008;SWT53;MN255;

To set the bottom two "bands" down 8 dB:

MN008;SWT53;SWT11;DN;DN;DN;DN;DN;DN;DN;DN;SWT12;DN;DN;DN;DN;DN;DN;DN;DN;MN25
5;

MN008 opens the "Rx EQ" menu.
SWT53 taps "clear" to set all Rx Eq to their midpoint (0).  "clear" is
SWH35; on a KX3.
SWT11 taps 1 for the first frequency "band" (for the K3).  See the SWT/SWH
table in the programmer's reference for keys 1 thru 8 on the K3 and KX3.
Eight VFO "down" commands (DN;)  reduces "band" 1 by 8 dB.
SWT12 taps 2 for the second frequency "band".
Eight VFO "down" commands reduce "band" 2 by 8 dB.

MN255; closes the menu.

I tried a few of the DNn; commands; it seems to decrement just 1 dB per DN
command.  You'll need 16 DN commands for the full range.

Not as pretty as the TE command, but the Rx EQ can be set with commands.

The worst case command length to set all 8 bands to one extreme or another
requires about 250 characters (a bit over twice the maximum command length),
but I doubt that you'd want an Rx EQ of all "bands" at either extreme.

Art WB7ENE I would tend to agree with you on the price.
When I built my first one I just bought and built it a stage
at a time.  It just makes me nervous that the other "stages" 
will be out of production in the near future.

I really used the antenna tuner but thought the noise blanker 
was weak.   I didn't put an internal power source in my last
one but figure I might as well get 'em while I can.
I loaded K1 with the extra module shipped to me is $611.35.

Thanks for the reply.
Stan

Before you mail-order ... check with a local sheet metal / air conditioning

I previously used the same approach of multiple UP or DN commands to use
different microphones before the TE command came out.  

I still use UP and DN to select the rear panel versus front panel mic jack
and to change the VOX gain.

I do those in DXLab's Commander module because I'm always using that when I
want to change microphones.

Arlen,

One thing to keep in mind regarding NB and NR is that only the NB can
actually (sometimes) reduce the noise floor to the point where you will be
able to hear weak signals that are far below the noise floor that you
would have when NB is NOT engaged. In other words, when engaged and
properly set for the offending noise, the NB --may-- actually drop the
noise floor to what it would be if the interfering noise were not there at
all.

So far, I've never heard any NR function reduce the actual noise floor.
Yes, it can make the noise a bit less annoying, but it will rarely, if
ever, enable you to copy a signal that you would otherwise be unable to
copy if NR were off.

All that said, the K3's Noise Blanker (NB) is the most effective NB that I
have ever used on any radio for the line noise racket that occasionally
threatens to infringe upon my ham radio time.

There is no 'secret recipe'.
As has been pointed out by several others, the NB settings must be 
adjusted to best deal with the noise you are encountering at any given 
time on any given band. Also, when dealing with the DSP based Noise 
Blanker, give it a little time to build the filter that will be used to 
do the job - count to 5 is a good suggestion. If you are using the 
hardware NB, you should hear the effects almost immediately.

Listen to the noise before deciding whether NB or NR is the proper tool 
to use. The NB works on high rise time, short impulse noise. It will not 
be effective at all on more constant noise sources like powerline or AC 
motor noise - those type noises will respond to the NR settings.

Noise Blanking is just what it says - it puts a blank 'hole' in the 
receiver stream, and yes the K3 allows you to adjust it to control not 
only the threshold where it begins to act, but also the width of the 
blanking. You as a listener must come to a compromise - if the blanking 
width is too wide for the transmission mode, those holes will begin to 
disrupt the communications as the width becomes wider.

With Noise Reduction, the DSP builds a filter around what it detects to 
be a coherent signal. It takes a little time for the DSP to sense that 
it has a coherent signal and build that filter. You will also find that 
the NR function will cause distortion when that filter is narrow. How 
effective NR will be depends on the relative strength of the noise and 
the signal that you want to hear.

So experiment a bit and you will become more adept at selecting between 
NB and NR as the occasion arises. It is not a "catch all" for all noise 
sources. Your selection and settings will vary from time to time and 
band to band. I suggest running most of the time with both NB and NR off 
and letting your brain do most of the filtering. When that is 
bothersome, turn the appropriate one on and find the best settings that 
attack your particular noise source.

Don W3FPR

Oh, yes, Tex is correct.? The moderator does not even have a name or callsign.? I was astonished by the moderator's stance because I simply wrote a sentence to concur with Tex's comments.

Very strange experience with KX3-yahoo group.? It is far better for me to stay in this formal elecraft mail listing.

Just? thought I would pass along my recent experience on the KX3 Yahoo Group. 
Yesterday I received a heatsink from KB8UHN.? I posted on the KX3 Yahoo
Group that I received a heatsink from KB8UHN and it was a quality product
and about half the price of other heatsinks.

About an hour later I get an email from the moderator telling me I'm banned
from group for promoting products.? I replied "Sorry did not know your
rules, you would think a warning? He did not respond to my query.? 

Johnny Siu VR2XMC told me he has been banned from posting on the group for
agreeing with my post about the heatsink.

So be careful on the KX3 Yahoo Group.? Somehow I will suffer through this
traumatic banning.

You want all the ATUs in the KX3 and KXPA100 bypassed if the KAT500 is going to match the antenna.  Do your tuning with about 10 to 20 watts out of the KXPA100.

Subject: [Elecraft] KX3 + JT9 -- any successes?
Message-ID: <53D97691.3090208@aa6e.net>

That's about right. There's no reason (after some warm-up) that the oscillator 
temperature should change by more that 0.5C (or whatever) over a 1 minute 
transmission -- unless your oscillator is sitting close to the PA heat sink like the KX3.

The KX3, like most amateur radios, has a weasely frequency stability specification.  
It says +/- 1 ppm typical over 0-50C. What's weasely about that?

1.  "typical", to begin with.  It means something like "your chances are pretty good 
it's within +/- 1 ppm if you are a normal user."  It's a weasel word, because you 
would have a hard time proving that your radio did not meet this spec.  (Problems? 
Well, you're just not typical.)  A more serious spec would be "worst case", but we 
hardly ever see a worst-case spec in the amateur world.

2.  What does 0-50C mean?  A reasonable user might think that means ambient operating 
temperature.  But it might just as well mean indicated oscillator temperature, which 
is around 38C for my idle KX3 at the moment, while my ambient is ~22C.

3.  What is the timescale?  A radio that flicks around +/- 50 Hz on 6 Meters would be 
in spec, but nasty even for SSB.  Most of us would probably assume that short-term 
stability should be better than long-term.  That would be true if we're talking about 
drift due to slow temperature changes, supply voltages, component aging, or 
whatever.  The published spec does not give much insight as to what to expect in 
practice.  The one minute on / one minute off that we have in JT modes is awkward for 
the KX3.  The oscillator "typically" sees a large temperature swing over a minute's 
transmitting -- several degrees C, depending on power setting.

For what it's worth, the Orion claims +/- 3 ppm stability (and accuracy - another 
issue) over its operating range, but its short term (1 minute) stability is much 
better than the KX3's.  I assume the K3 would be similar to the Orion, but sadly 
there is no K3 on my desk.

This sounds like splitting hairs -- a good description of JT9 decoding!  The KX3 is a 
fine radio for most applications, just not bleeding edge digimodes.

I admit to being fascinated by precise time and frequency.  I particularly like the 
new Flex 6500/6700's GPS stabilized option, 5 x 10**-12 over 24 hours, for a price.  
That might support JT9 at 20 GHz.  Even there, the devil is in the details. They 
don't give fluctuation vs timescale info.

Maybe he's holding the temperature to 0.5 deg C

Sadly, The KX3 Yahoo group has taken a very bad turn. It was originally
started, when the  KX3 was initially announced, by a very responsible group
owner who had a very lenient moderation policy. Unfortunately, he has turned
the day-to-day operation over to two other moderators that prefer to remain
anonymous. They have instituted a Draconian zero-tolerance policy of any
mention of either commercial products, or links to any other resource pages.
They claim to want all KX3 related material to be copied to the Yahoo Group,
rather than links to other sites. This is unworkable, as only those who
actually own the information can post it there. It also make maintenance of
updates unworkable. For instance, I posted a link to a website that was
still maintaining an archive copy of NaP3 software (N8LP), after development
of NaP3 ceased. For this, I was placed on moderation (unannounced and
unexplained).
 
Unfortunately, the implementation of these new policies has resulted in the
banishment of many, often without explanation. Sad to say, this once very
useful Group is now much less so.

Hi Bruce,

I appreciate you cc ing me into your post, but I really need to say that
your comments are very unfair and unfounded.

You obviously have no idea what is involved in growing and maintaining a
large group such as the KX3 group.

Yes, there are probably a few who have been banned from the group that
perhaps should not have been, but that is only a small portion compared to
the amount of spam and obscene, nasty and down right rude stuff that we are
forced to filter, and do stop.  You have ZERO CLUE!

It seems that I can not please everyone all of the time, I will live with
that.

One reason discussions about things like heat sinks have been "tempered"
was that in the recent past, they have lead to several arguments and
unproductive discussions about copyright theft etc, and even evolved into
racial slurs.

This group was not founded, grown and maintained so that a few individuals
can come in, not contribute to the greater good of the KX3 community, but
then attempt to divert/steal traffic and visitors for their own profit and
marketing efforts.

So as much as you have chosen to focus on the bad as you see it, you are
missing 99% of the good that has gone on.

I don't profess to have been perfect, but for a "hobby (my time
volunteered)" I think I, as well as others have done a decent job of
growing the KX3 group to the size it now is. I would also suggest that the
BULK of the group is very happy and are getting value out of this
particular group.

To recap, the heat sink discussion is really old. The recent posts that you
are questioning, which resulted in privileges being removed, were inciting
in nature.  There is no need to choose sides and reopen the debate. We are
simply just trying to stop those who like to stop by, toss in a grenade and
leave a mess that we then have to deal with.

But I guess if I was just sitting in my armchair and doing some Monday
Morning Quarterbacking, I would think it is all easy too.  But I am not, I
am in the trenches trying to make everyone happy and keep the group on
topic.

None the less, thanks again for your valued input.

73 Bob VE3UK.

The ?about? message for the group prohibits spamming, advertising, and commercial messages. Saying ?I bought this and I like it? is not any of those and is not a basis for banning someone.

I?ve run many large mailing lists and I know how much work it is. I rode herd on 5000 Hewlett Packard engineers in nearly 100 newsgroups.

I don?t think the heat sink topic is getting old, rather it is a popular, hot topic of interest to many KX3 owners. Over the past six months, three or four aftermarket heat sinks have come on the market. That is a big deal and people are hungry for information. Yes, it will be repetitive, right up there with setting the mic gain to 4-5 bars.

If people are misbehaving, warn them on the list, in public. That lets everyone know where the limits are. Personal attacks and slurs are obviously over the line, and need to be called out as such.

I agree that the K2 is a great kit. I enjoyed building and using it much more than the KX1. The K2 is very easy to work on, and the alignment is fairly easy, although conceptually a bit more challenging than the KX1 or your typical QRP CW tri-band kit. I learned a lot from studying and building the K2, and intend to hang on to mine too.

Hi Stan,
If it were me, and I had the time, I'd love to build the KD1JV
tri-bander.
The parts layout looks straight-forward...may be done in a week-end.
The Analog Device AD983 looks like a really fun chip to play with.
And the kit incorporates a display and filtering.
I think for the price, 3 bands is a pretty good deal if the unit
operates as expected.

What ever you decide....I hope you have fun with it :-]
And let us know how you liked it.

There are now numerous on-line metal distributors.  Most are regional so 
I would try Googling "copper metal distributor" and you'll likely find 
one in your area.

I needed some aluminum plate a few years ago and there was one in an 
industrial park nearby.  I called them and explained what I needed. They 
had some cut-offs and got me exactly what I needed.  The price was 
reasonable too and I picked it up later that day.  If I recall they had 
aluminum, steel, copper, brass as well as alloys and plastics.

Yeah, same thing happened to me. I said buy from the original and not the guy who started making COPIES of the KX3 end plates. I said I thought it was very UN-amateur to ripoff someone else's design. I was told that my comment was unacceptable so I removed myself from the group in disgust. If it is his friend and he is going to be so against telling the truth about him then he shouldn't be the moderator of the group.

Message-ID: <53D9C10C.70607@bellsouth.net>

Looking for a very small speaker that has bass, treble, & volume 
controls I came across this one at Radio Shack, but are sold else 
where.  Can run off 3 AA internal batteries or USB.  I have used the 
little speaker for 3  months and been amazed how good it sounds. 
Description says stereo, but it only has one speaker with a good size 
magnet.  The phone plug is stereo.  Sounds great on the KX3 & number of 
other rigs I use from time to time.  For those, like me, that don't hear 
all the audio frequency this helps a lot.  Also has plenty of volume.

Did you ever find a solution?  My Line in is also dead, it takes more than
15mw to get any tx power even at maximum line in gain. There is no ALC
action until I hit about 15mw audio in.

I know the audio output amps fail (mine have a few times, with stereo
plugs), but what is the most commonly failing component on the line in audio
path?

Your setup may be different from mine, but when I find that I do not 
have TX audio from the Line In, it is because I forgot to change the 
mode from USB/LSB to DATA.  But I have mine set up to use the MIC jack 
for voice modes and the Line In for data modes.

Hi:I have a K2 QRP rig with a built-in ATU. Are there any suggestions on how
I could use the K2 to estimate the input impedance of my antenna, or at
least see if it is in resonance?Sure enough, I can simply make the ATU find
its best match, but I would like to know if the antenna itself actually was
close to resonance or even estimate its input impedance, as measured at the
K2 antenna connector. Can I measure the antenna SWR and bypass the ATU while
I am doing that, to get at least an idea?73 - Kristinn, TF3KX

You?can measure the SWR by using KAT2.? The details are given on page 19 of the KAT2 manual.

Kristinn,

After doing a TUNE that hopefully ends up with a low SWR, you can look 
at the ATU menu parameters for Lxx.x, Cxx.x and NET x to determine the 
configuration of the L network that the ATU found for the match.
You can then solve the L network equations to find the impedance of the 
end of your feedline in the shack.
See page 21 in the KAT2 manual.

Don W3FPR

Thanks. Yes, I can determine the tuner settings (L/C-values, etc.) and from
the network equations derive the impedance these settings match into. It
would be neat if the K2 had enough CPU power and memory to carry these
calculations out for me and just display the R+jX. Perhaps a good project
for a small program or an app...

It took me some time to get FSK RTTY working properly with the K3/0 Mini
and the Remote Rig interface.  Getting it to work smoothly with Writelog
was especially challenging so I decided to write up my settings and
connections and pass that info along to others who might be having as much
difficulty as I did. I also use MMTTY standalone, N1MM, and the Remote Ham
Radio service, so I included those details as well. I have posted the
article in PDF format here:

I hope you find this information useful.  Let me know if you have trouble

Of course you realise that the output impedance of the ATU will be the complex conjugate of the impedance at the rig end of your feedline. However, if you want to know the impedance of your antenna, you need to realise that the feedline is acting as an impedance transformer, and you need to take into account factors such as length of feedline, frequency of operation characteristic impedance and velocity factor of the feedline, etc..

There is a program, SmithSmith http://www.ae6ty.com/Smith_Charts.html
which can also solve the impedance at the antenna. Set the ATU L and C
and the coax feed-line as constants then adjust the antenna parameters
for 1:1 SWR at the input.

The program is SimSmith (simple typo) and I agree with John that it is a 
very useful one. I have used several other implementations of Smith 
Charts and this one is by far my favorite. Fairly frequent updates, and

Hi Matt,

I wonder if this is correct

IMO, the task of the tuner is to make the tx happy, so it can look into the
load it is designed for. Thus, it will translate the impedance as seen from
the antenna connector into something as close to 50 ohm as possible. The
tuner will not change anything on the feeder. With or without the tuner,
the feeder will have the same VSWR.

Per-Tore,

Yes it is correct.  He stated that it is the impedance at the rig end of 
the feedline.
That will not likely be the feedpoint impedance of the antenna. That 
impedance can be found if you do the calculations for the impedance 
transformation of the feedline (for which the length of the feedline 
must be known).

Subject: [Elecraft] Auto Notch Revisited.
Message-ID: <1406840474745-7591810.post@n2.nabble.com>

It's been 2 years since there were complaints on this forum about the K3
auto-notch.  Apparently it was never fixed.  

The other day I was working a Ham in Tel Aviv when a carrier came on and
covered his signal.  The Auto notch worked well but the guys voice was very
distorted.  To me that's unacceptable.  

This year at the Dayton Hamvention I talked to someone from Elecraft about
the DSP problems and he agreed that the auto notch needs some improvement. 
I think he was a the product manager.

Back in the early 90's I worked with another Engineer on a project we called
"The Hamblaster". I published two articles in QEX (October 1991 and January
1992). We developed a PC based sound card that connects to the receiver's
audio and performed, among other things,  an auto-notch and noise reduction
(NR).  In our DSP software, the auto-notch was generated by summing the
inverted NR output to the input signal.  Whether it's a noise reduction or
an auto-notch we still used a software algorithm called the LMS (Least Means
Square).   

Most Ham transceiver use the same LMS algorithm and I never heard distorted
audio when the notch was engaged.  That's especially true with Yaesu, Icom
or Kenwood. I'm not sure about the other American brands but I bet they are
OK as well.

My second complaint is the K3's NR control.  Most other manufacturers have
an analog like control that simply changes the NR level.  I don't understand
the logic of having several steps from F1-1 to F4-4 and F5-1 (mixed) to F8-4
(mixed).  I would rather have two separate settings.  F0 to F9 for the level
and if you want a to fiddle with the delay, D0 to D9 in the main menu.  I
think the level control on other radios is simply a mix of the input signal
with the NR output and is similar to the K3's mF5-1 to mF8-4 

To me it sounds as if there's a dynamic range problem on the K3 whereby the
numbers in the math are over-ranging when the notch is engaged and is
causing a "flat-topping" in the audio signal.  But that's just a guess!   

I hope someone at Elecraft reads this and gets the ball rolling to fix the
problem!

I completely agree - the K3 is very lacking with their auto-notch. It 
requires fiddling with the AGC menus to force it to function without 
ruining the fidelity of a SSB signal. The NR system is very complex with 
many settings - none of which I have found to be very helpful - 
certainly no better than just using my ears.

The subject has been brought up several times since I became interested 
in the K3 and started following the various reflectors and groups. They 
are both weak points of the K3 and should be addressed.

Most other currently available rigs are easier to operate in the NR 
arena and much more pleasing to listen to in the auto-notch arena.

I have found some work-arounds and mentioned them in previous posts. 
That said, why are work-arounds needed???

Hi Don,

I still doubt that this is correct.

The L/C values given by the tuner, are the values as seen from the tx side.
It is the values that will make the tx happy. It does not say much about
the impedance at the rig end of the feeder.

In order to change the VSWR on the feeder itself, one has to put the
matching network (tuner) between the antenna and the feeder.

BTW, the tx is probably not conjugate matched by the tuner. Conjugate
matching does not apply to transmitters or power amplifiers. But I realize
there is a huge dissension in this area too. ;-)

I agree with the majority of your assessment.  I also brought up the Auto
notch issue several years ago and haven't seen much, if any improvement.
 As a result, I nearly always just use manual notch.  I also have the same
complaint with the way the NR in the K3 works.  The KX3 implementation is
far superior, IMO.  I've actually considered coupling an AF DSP speaker
product from West Mountain Radio to the K3 to overcome the K3 autonotch and
NR limitations.  I've used one of their speakers mobile for many years
coupled with my IC-7000 with a lot of success.

I think I see where the confusion has arisen. Here we are talking about a K2 with integrated KAT2  ATU. So, when I used the term "rig end of the feedline", I was referring to where the feedline connects to the KAT2 BNC connector at the back of the K2, which is the output or antenna side of the KAT2 ATU. In order to make the impedance where the antenna connects to the KAT2 output look like 50+0j ohms, the KAT2 will use an LC network to transform the impedance. The impedance of this LC network together with the 50ohms of the K2 final PA output will be equal to the complex conjugate of the impedance you will see looking into the shack end of the feedline leading to your antenna.

For example, to keep the maths simple, let's consider a case where the impedance at the end of the feedline in the shack works out to be 50+j100ohms. That is, the antenna is slightly inductive. In order to transform this impedance to 50ohms, you could connect a capacitor in series that has a reactance of 100ohms to cancel out the inductive reactance of the antenna+feedline. If we look at the impedance of our matching network plus radio, we see the capacitor in series with the 50ohm transmitter, so the impedance looking into the "ATU" plus transmitter is 50-j100 ohms. This is the complex conjugate of the impedance looking down the feedline towards the antenna, which we already see is 50+j100ohms.

In a more complicated scenario, the resistive component at the shack end of the feedline may not be 50ohms, and our matching network will be more complicated, and we will connect some reactance across the feedline and/or transmitter to achieve the required impedance transformation. If you go through the maths, you will again find the impedance looking into the ATU+transmitter is the complex conjugate of the impedance looking into the feedline+antenna.

Hi list,

Isn't an RF transmitter or PA actually more like a current generator? Its
internal resistance is kept low in order to reduce internally dissipated
power, with consequent reduction in efficiency. It is usually designed to
work efficiently into 50 ohms.

It is important to know the difference between these two statements:
(A) The transmitter has a 50 ohm output impedance.
(B) The transmitter is designed to work into a 50 ohm load

A transmitter will be able to put its rated power into a 50 ohm load, but
this says nothing about its output impedance. That is why I don't think
conjugate matching will be appropriate.

(Hope this is not getting too much OT now)

Per-Tore / LA7NO

Per-Tor,

The tuner (if properly calibrated using a 50 ohm non-reactive load) will 
show close to 1:1 SWR at the tuner *input* after a TUNE - it is close 
enough that it is practical to assume it is 50 ohms resistive.

After that TUNE, the Lx.xx Cx.xx and NET x ATU menu parameters will 
indicate the inductance, capacitance and L network configuration that 
were used in the ATU to achieve that match.

Working through the L network impedance transformation using a 50 ohm 
input will produce the impedance at the output of the ATU.  That will be 
the conjugate of the impedance presented in the shack by the feedline.

You are correct that an ATU does *not* alter the VSWR on the feedline - 
it is only capable of altering the VSWR at the *input to the tuner to 
make the transmitter PA stage "happy" with the 50 ohm ATU input impedance.

I don't think the original poster nor any of the responses made any 
inferences that the feedline impedance was being changed.

I think we have hit the posting limit for this topic, so I'll just finish with this remark: the maximum power transfer between a power amplifier and its load will occur when the source and load impedances are complex conjugates (this can be seen using the voltage divider equation and some differential calculus). In the case of a purely resistive load, this reduces down to the source and load resistances being equal.

Matt,

I believe it is even more 'simple' than that.
When the ATU wattmeter is properly calibrated, it is then set to measure 
an SWR of 1 at 50 ohms resistive load.

When a TUNE produces an SWR=1, the impedance at the input (coax inside 
the K2) has been transformed to 50 ohms, so that is a known quantity.
The ATU L and C show the values used to arrive at that transformation, 
and the NET parameter indicates whether the capacitor is on the input or 
the output side.  So the L network values and configuration are known.

It is then a task to solve the network equations for an L network having 
series L and shunt C elements to arrive at the output impedance.

Yes, the transmission line impedance (at the BNC connector) will be the 
conjugate of that impedance.
Nothing has been said about the SWR on the feedline nor the feedpoint 
impedance at the antenna.

73,
Don W3FPR

So, when I used the term "rig end of the feedline", I was referring to where the feedline connects to the KAT2 BNC connector at the back of the K2, which is the output or antenna side of the KAT2 ATU. In order to make the impedance where the antenna connects to the KAT2 output look like 50+0j ohms, the KAT2 will use an LC network to transform the impedance. The impedance of this LC network together with the 50ohms of the K2 final PA output will be equal to the complex conjugate of the impedance you will see looking into the shack end of the feedline leading to your antenna.

In order to transform this impedance to 50ohms, you could connect a capacitor in series that has a reactance of 100ohms to cancel out the inductive reactance of the antenna+feedline. If we look at the impedance of our matching network plus radio, we see the capacitor in series with the 50ohm transmitter, so the impedance looking into the "ATU" plus transmitter is 50-j100 ohms. This is the complex conjugate of the impedance looking down the feedline towards the antenna, which we already see is 50+j100ohms.

If you go through the maths, you will again find the impedance looking into the ATU+transmitter is the complex conjugate of the impedance looking into the feedline+antenna.

Would not this imply a maximum efficiency of 50% ?

Hello David,

I concur with your observation.? There are many areas that?K3 are better than ic756 pro 3 but the NR, manual notch and auto notch of K3 have much rooms for improvement.

When there is a strong undesirable carrier next to a weak DX, in 756pro3, I can use manual notch to 'kill' the carrier and eliminate the pumping effect on AGC.

Every radio has its own merit.? We have to accept their weakness while we are enjoying their strength.

Anyway, I would like the NR of K3 will be as good as the NR of KX3.? At one time, I nearly sold the K3 and just kept the KX3.? On reflection, K3 is still a good contesting machine at desktop size, hence I still keep my?K3.

P-T,

If one uses the voltage divider example, yes the maximum efficiency is 50%,
But the output of a PA stage is not a resistor, and the collector load 
"resistance" is set by the designer to produce the output power desired.

The 'resistor' assumption is a simplification that can be used when 
constructing equivalent circuits to analyze the voltages and currents in 
the network that follows the perfect generator.

The theory of large signal amplifiers is too great for detailed 
discussion on this reflector, so we usually have to settle for 
simplifications.  An equivalent circuit is not a full representation of 
the workings of an actual PA stage.  I believe that is where the 
misunderstanding comes from.

You are correct Per-Tore.  Looking into the male connector on your 
feedline, you will see *some* impedance which depends on the impedance 
at the feedpoint of your antenna, the characteristic impedance of your 
feedline, and the length of your feedline ... with one exception:

If the feedpoint impedance of your antenna is totally resistive, *and* 
is exactly equal to the characteristic impedance of your feedline, then 
length only matters when calculating loss.  This situation hardly ever 
occurs for any real hams however. :-)

The KAT2 "antenna tuner" does not "tune" the antenna, or anything else 
for that matter.  It is simply an L-C network [L-network in the KAT2] 
that transforms the complex impedance seen at the BNC connector to what 
the PA output filter wants to work into ... nominally 50+j0 ohms.  Once 
you get a match and find out the L, C, and configuration of the 
L-network in the tuner, you can use the L-network equations to determine 
the impedance transformation taking place in the "tuner" and thus the 
complex impedance looking into the feedline connector

If you know the complex impedance looking into the feedline connector, 
the characteristic impedance of the line, and it's length, you can use 
one of many programs to calculate the impedance of your antenna at the 
feedpoint.  I use N6BV's TLW which comes on the CD with the ARRL Antenna 
Book, but there are many other ways, including paper and pencil on a 
Smith Chart.

And yes, you are also correct that the presence of the tuner will not 
affect the VSWR on the feedline, nor the loss incurred by that VSWR. 
Hope this helps.

Message-ID: <q9fwvx75r4lkna5wk0ght8rp.1406848969367@email.android.com>


My K2-10 is my backup rig. It has an internal homemade transistor amp keyer that keys the AL811H when 100 watts is needed.?

I would like to add the KXPA100 to have the option to fully drive the AL811H when needed, or to run 100 watts without tuning the larger amp.

What would be the best way to key both amps at the same time? ?Any other considerations that I should know for setting up this configuration? For those that may ask, ?the reason I want to use the KXPA100 instead of the internal K2 amp is so the radio will still be available for qrp backpacking and such.?

Thanks for your help!?

Agreed, now let's hope somebody IS listening and get this long term issue
resolved.

The Manual Notch eliminates a CW carrier nicely but it too requires button
presses and adjustment that could be simplified surely?

I fully agree.

But will not a conjugate match also imply a max efficiency of 50%

I put my KPA100 and KAT100 in a separate EC2 enclosure.  This allows the 
K2/10 to be unhooked and taken portable.  It also provides the key out 
jack for driving a larger amp in the shack.

I rarely use the manual notch on CW, I've had other rigs with notch 
filters, and I rarely used them either ... it seems that the filter in 
my head is enough.

I'm not on SSB very much [compromised hearing, not mode-aversion], and 
I've occasionally used the auto-notch on SSB when in 
longer-than-a-contest-QSO mode.  It's always worked very well for me.  I 
suppose there is some accompanying distortion, that's what happens when 
you punch out a narrow part of the baseband, but honestly, it reduced 
the carrier to where I couldn't hear it.

I think, but do not know, that the performance of several of the K3 DSP 
"features" are closely related to the AGC parameters being used.  This 
makes sense, the AGC is distorting the signal possibly before the other 
"features" are getting the number stream.  All of that is above my pay 
grade.

I notice on MARS frequencies (slightly outside ham bands) that my power output starts out low and builds to full output over 10-20 seconds of transmit. The symptom is easily observed during an MT63 transmission and receiving stations comment that my signal starts out light and builds to a strong signal as the transmission progresses.
I have run the calibration routine several times into a dummy load and all seems to go well but the problem persists.
I see the same symptom in some ham bands but to a lesser extent, perhaps starting at half power and coming up to full power in a 10 seconds.

Has anyone else experienced this or have ideas about a fix?

P-T,

No, a conjugate match will assure 100% power transfer.

Look at it this way - what the conjugate match says is that if you cut a 
transmission line at any point, looking one way at that cut point, you 
will have some impedance - example is 70 + j20.  Now look the other way 
and the impedance will be the conjugate match - 70 - j20.  That is the 
condition that exists.
It also happens to be the condition for maximum power transfer.

Since that cut can be made at any and all points along the transmission 
line - think what would happen if the efficiency at each of those points 
(when connected together) were 50% - nothing would get to the antenna.  
So we know that 50% is *not* the efficiency of any and all junctions of 
any conjugate match.

Mixing the conjugate match concept with the maximum power transfer 
theorem is getting us into confusion - there are 'holes' in that 
combination.  Yes, they work together, but not seamlessly.
If a generator has an internal impedance of 50 ohms, the maximum power 
transfer will be only if the load to that generator is also 50 ohms.  
That says nothing about a conjugate match.

Now to further complicate things, the internal impedance of a generator 
has nothing to do with the efficiency of that generator - especially if 
we are discussing a PA output stage.  Bringing the conjugate match 
concept into the internal design of a PA stage is in error - it just 
does not work that way.  The conjugate match only applies to the output 
of that amplifier stage.

In other words, if we send 10 watts into a feedline (or ATU), all 10 
watts will go to the load (antenna) except for losses in the feedline.

I am not about to embark on the design and efficiency of a PA stage on 
this reflector, so take the conjugate match and maximum power transfer 
theorem only to the terminals at the PA stage and all will make sense.  
They do not apply to the internals of that stage.

Most interesting discussion ~ and my comment ~

I bought an Elecrfat K2 in 1999 but also a Kachina 505DSP (a software 
controlled transceiver)
The Kachina has a subroutine ~ when activated, it displays a Smith Chart 
of the current conditions
of the match, in a separate display window --- always thought that was 
rather a nice feature ---
Maybe some newer Elecraft transceiver might include this feature in the 
next decade?

Jack,

I would suggest that you do not have sufficient audio drive.  That is 
the normal behavior of Elecraft products in digital modes when the audio 
drive is low.

If you are following the typical 'wisdom' of using the audio level to 
control the output power, forget that - the Elecraft transceivers are 
different in the way they control power, and that method will not work.  
It will produce exactly the symptoms you state.

For the K3 and KX3, adjust the audio so the ALC meter shows 4 bars solid 
and the 5th bar solid, then adjust the power knob for the desired power 
level.
If you have a K2, set the LED display to show ALC and adjust the audio 
until you see 1 bar of ALC, then back down the audio until that bar just 
goes out.  Again, adjust the power level with the power knob.

73,
Don W3FPR

The trouble with the K3 notch is that it is outside the agc loop(audio notch)
unlike the Icom radio. It may notch out the tone but not the carrier. A huge
signal will still swamp the receiver. You will get arguments that this is
better on receiver imd performance but I think I could live with receiver
imd degradradation for the small if not brief time I would use the  inside
the agc loop notch.

I will be on a mountain top in the Cascades this Sunday for a Summits on the Air (SOTA) event.  Is there anyone who would like to fill in this week.  It?s at 1800Z on 14.3035 MHz.  It?s not difficult.  How about one of you regulars who should have the hang of it right away?  BTW, John, N6JW, won?t be available this week either.

73,
Phil, NS7P

The Icom?s manual notch is inside the AGC loop, but not the auto notch.

The early (Version 1) Orion firmware had the auto notch inside the AGC loop, and it was one of the many great features of that radio.  In AM mode, you could punch in audo-notch and it would remove the carrier to let just the sideband energy drive the AGC ? which often made uncopyable low-modulation percentage AM signals readable.  And of course, auto-notched interfering carriers would not affect AGC.  When Ten-tec completely rewrote the software (Version 2) they moved the auto notch outside the loop, and there were universal complaints (at least compared to how the notch worked in V1 firmware). It?s unfortunate that there were other factors that eventually led to the rewrite. 

Obviously there are design tradeoffs, and I don?t fully understand them all.  But it does seem that it?s feasible to put a manual (e.g. non-adaptive) notch inside the AGC loop without doing too much damage to IMD or other specs. Maybe even do it as a menu selectable option if there are performance tradeoffs.
