Hi john,
I think I've seen this myself. I would redo the power calibration with the K3 utility and a good dummy load. I'm interested in hearing people's responses to your question.

My K3 s/n 4487 has exhibited similar behaviour since I built it in 2010.
Despite calls to Elecraft Support no solution was found despite Gary talking
me through various items until a month or so ago when the spike was causing
problems with my amp on 24 Mhz.  It was mentioned that the K3 must see 13
volts whenever it is transmitting and to check this on the front panel by
tapping the Display button. Mine showed 13.6 volts on receive and 12.6 volts
on Tx. Turned out my old power supply regulation was faulty. Anyway after a
power supply rebuild and further check it now shows 13.6 volts on receive
and 13.3 volts on Tx at 100 watts output. A further TX calibration completed
the process and so far no power spikes! So check your power supply is
supplying sufficient voltage on key down.

I've noticed that the first time I TX with my KPA500 it will fault. Seems to settle down after that. May also spoke after band change.

Hello,

Have you always wanted an Elecraft? A KX1, K1, K2, K3, whatever? 
Does your K2 need a tuneup?
I build and service them all!

See what my clients have said about my construction and service work at 
http://www.eham.net/reviews/detail/6768

Photos of the popular "Twins" -- the KPA100 and KAT100 in EC2 enclosure --  are at

Hi John,
My power dances all over the place (my serial number is 00069).  Just had a quick QSO with the KPA500 indicating 560 watts at the beginning and then going down to 480 at the end.  That is typical.  My 12 volt supply drops to 12.2 on transmit, 13.3 on receive.  I have a long 12 volt  cable from the supply so  ?I" squared losses are understandable in the cable. Driving power from the K3 is variable per band but typically set to 25 watts or so.  The QSO described above was on 17 Meters and the drive is 25 watts there for ~500 watts out or just below after stabilization. 

I remember the power fluctuation issue being discussed years ago on this reflector and it was explained that the power control uses a sampling and feedback loop that takes ?time? to stabilize.  That said, I believe we are both experiencing some power fluctuation over 10% in a short period of time.  Depending on the amplifiers we are using this could cause real downstream issues, like distorted signals, spurs or alarm faulting of smart amplifiers. 

Could we have some aging component that is aggravating this issue?  Our K3?s are among the oldest on the air.

Thanks David for posting this.  I noticed this from time to time with my 
old K3 and now also with the new K3S.  I keep the KPA500 output set to 
around 400-450 watts most of the time and notice spikes to 550 or so on 
the first or second dit when sending CW at times.  I just built the kit 
and have done the TX calibrations properly and they all passed via the 
Utility program.

I'm using the factory supplied #12 gauge power cable and the power 
supply is a pretty well regulated MFJ 4245MV switcher (RFI quiet here).  
This supply is adjustable and evidently the meter isn't totally accurate 
or there is a larger voltage drop in the cable than I thought there 
should be.  I checked the K3S' meter display after receiving this email 
and it read 13.2 volts.  Keyed to 13.8 volts on the meter, but at 20 
watts out, driving the amplifier, it dropped to 12.6 volts while keyed.

In line with your findings, I set the MFJ supply to read 13.8 volts on 
the K3S display and it now only drops to 13.3 volts under the 20 watt 
load.  The occasional power spikes seem to have disappeared, so it's 
something everyone should take a look at if they do experience the power 
spike problem.

Again, thanks for posting this David.

Well you sure do beautiful work, my compliments. I had such a good time
building my first K2 and my K3, I'm sorely tempted to build another K2 for
the fun of it. And I'd imagine Elecraft is eventually going to start having
problems sourcing parts for it, so I should probably get on with it sooner
rather than later....

Not to worry, my K3S does it too :-(

Bill,

Is there any way that you can increase the power supply voltage to 13.0 
volts or more during transmit?  If so, that should help.
Most of my experience with power control is with the K2 which starts out 
at lower than the requested power after a band change or a change in 
power level, but quickly builds up to the requested power.  The result 
is a lack of power spikes.
I figured that the K3 power control is similar, and if so, I would not 
expect power spikes at all.  Perhaps the power control loop should be 
investigated for critical damping.  If power spikes occur, that is an 
indication that the control loop is underdamped.

If the control loop damping is the problem, it is possible that this is 
not a problem for all K3s - the loop gain will may vary depending on the 
gain of the transmit RF stages, and while one K3 may have this problem, 
another may not (that is the case with the K2).  The RF Gain also varies 
from band to band, so there may be a difference in that behavior 
depending on what band is used.

73,
Don W3FPR

to run, and run well, off of batteries. These power spikes makes it 
sound like that is not the case? Or am I missing something?

Batteries start out at 12.6v and go down from there. The K3/K3s needs 
to run well down to something like 10.5 to 11v. But if they need at 
least 13v to prevent power spikes . . . .

Power supply stability. Built cheep, get worse with time, insufficient heat
dissipation due to endless complaints about fan noise, cut corners on
components, too small wire to rig, yada, yada, ad nauseum. Power supply
issues can cause rig overheating, spikes, slow power build up, unstable
power output, audio distortion, hum, frequency drift, broad signals, even
key clicks, various issues with following amplifiers, just to get started
on a long list.

Plus the still-valid old timers' warning: ALWAYS do the work to RULE
OUT external issues -- connectors, cabling, coax, antennas, programs, power
supplies, misunderstanding or ignorance of the manual, power spike
scrambling memory, braine pharte, BEFORE tearing apart or sending rig back
to factory, or deprecating the manufacturer on public media.

Sticking to that rule over a lifetime will save 90 per cent of angst and
trouble relating to station apparent rig malfunctions.

For what it's worth, I've found over the years that battery power is less
innocent than you'd think when powering electronics. Especially on a tired
or cheap battery with a high internal resistance - those can drop a
surprising amount of voltage under load with unexpected timing, etc. even
when fully charged and not heavily loaded. This can really wreak havoc with
things that need well-regulated steady power... 

So I'd agree that this should probably be trouble-shot on a good power
supply. The spiking behavior may not be something fully within Elecraft's
control...

Most of the dealers are showing the 7300 as either in stock or soon to 
be in stock at $1499.  Unique, in that it is a direct sampling receiver, 
has a live scope, and depends upon a touch screen for control. Not

also wonder if it will be as flexible in operation as a KX3. Ah

If a power supply sags when lots of power is being drawn, it will affect whatever is trying to draw the power. For a transmitter / amplifier, that means the output power is most likely going to sag as well. The extent of the sag is directly related to how much the power supply sags, which, of course, depends on how well it is regulated. 

For the K3, we recommend well regulated power supplies with short supply leads. If the supply is rock solid and well regulated, you should see little voltage drop. Likewise, if you are using short, large wires from the supply to the K3, you will lose little power in that link. Remember that there is power loss in cable, and long skinny conductors will heat up and lose more power due to IIR losses than short fat wires. The K3 will try to correct power output variations, but if the supply / cabling problems won?t allow that, then it cannot. At the same time, it is quite possible the original poster needs to rework his power calibration (again). He had a major change in the components in his transceiver, and over time and use they will age and cause changes. For him, I suggest talking to customer support.

The second area is the KPA500. The HV supply is not heavily regulated, by design. It has a pair of very large capacitors on the supply, but when high power is being drawn, the output voltage will sag. This is quite normal. Thus at the start of a transmission the voltage will be high, as will transmitted output power, then will quickly sag to the nominal output value. This can also be affected by power cabling. Some operators may see more sag than they should due to long power cables. We usually see this with amplifiers plugged into 120V outlets. Make sure your 120V cable is large and as short as possible, AND make sure the 120V wall cabling is likewise large. I believe the NEC specifies 12 gauge wire for outlets, my experience with that size is very good. If you can use a 240V supply for the KPA, then it is much better. As pointed out above, power losses in wire is I*I*R. Since current will be dropped in half when using 240V over 120, the cable power losses will be one-quarter with 240 when compared to 120V.

Perhaps it might be time for some of us to perform their annual system check and maintenance, starting with the shack power supply? I?ll start this round with my own station today!

Since the 7300 uses direct sampling, it will have the same blocking dynamic range (BDR) problem as other radios in this class, especially multi-signal situations such as contesting. I also doubt it will beat the KX3 in close-spaced dynamic range, unless they used a very exotic, very expensive A-to-D converter. (Note that the only way the Flex 6700 series can achieve good close-in dynamic range is by turning on the preamp. This overcomes the very poor preamp-off MDS, but at an even greater cost in BDR.)

Beyond that, the KX3:

 - is about 1/5th the size
 - is about 1/5th the weight
 - consumes probably 1/10th as much RX-mode current
 - has an internal battery 
 - has an attached keyer paddle
 - has built-in stereo audio and CW/RTTY/PSK31 text decode with a PC
 - works with integrated peripherals (PX3 and KXPA100) that can be left at 
   your fixed station when traveling 

So if you're operating portable, it's an apples/oranges comparison.

Typo. I meant "without" a PC. (But it will also work with one :)

FWIW, I power my barefoot K3 with batteries and a solar charger. 
After our club county expedition for the California QSO Party 
(CQP) last year, I had a new appreciation for the way low power 
supply voltage could make a clean transmitter dirty.

To address this problem at home, I got a N8XJK Boost Regulator 
from TGE. This device boosts the battery voltage to the radio. 
Mine shows 13.9 volts, receive and 13.4 volts key down at 100W 
on 160M. I normally have it set up to only boost voltage when is 
senses RF output from the transmitter. (I need to talk on SSB 
before it cuts in.)

I have not noticed any RF noise on receive when I put it into 
"always on" mode. For a single radio setup, any RF noise it 
might make will be completely masked during transmit. We'll see 
how it works in multi-transmitter setups when I take to next 
year's CQP.

YES!  In addition to being a great mobile and fixed station rig, it's a 
backpacker's dream! Last summer, I loaned my KX3/KXPA100 with a 20Ah 
LiFePO4 battery to AF6RT and W6JTI, who dragged it up a 2 mile trail 
with a 1,000 ft gain in elevation to light up a rare 6M grid. They were 
also dragging an antenna, coax, a computer, water, and lunch. At the end 
of the day, they still had power left in that battery.

Hi Bill,

This is quite interesting to me. I run SO2R, so I would be concerned 
about noise in the second radio while transmitting on the first. Do you 
have a way to check this?  A second radio that can listen on other 
bands/antennas for weak signals while your tranmitting?

Thanks and 73, Jim K9YC

If one is not a backpacker or wants 100W output - perhaps for mobile
work - the "traditional knob" interface, built in tuner, support for
the AH-3/AH-4 tuners at the antenna, 100W, etc. make the IC-7300 quite
interesting.  IIRC, the 7300 will do PSK31/RTTY with an internal
decoder and attached keyboard.  Icom's claimed RMDDR and phase noise
specifications will, if accurate, put the 7300 in the top echelon of
Sherwood's test results.  The 7300 has what appears to be relatively
"tight" preselectors which should minimize the "composite signal level"
ADC overload (much more than the Flex-6300 with no preselectors) and
those with limited antennas (e.g. mobile, compromise wires, etc.) are
even less likely to see the strong signal composite overload than
someone with big antennas high in the air.

My disappointment is that after claiming the 7300 would be an "entry
level" rig, the price is well above that of Icom's other entry level
rigs (the IC-718 or IC-7100).  At the announced price, the 7300 should
have included a RX ANT Out/RX ANT In "loop," support for a second
antenna, and a video output to feed a larger display.

At its size and power level the 7300 is not the "backpacker's special"
nor was it intended to be.  To make that comparison is patently unfair.

I guess you get what you pay for. To my knowledge, only Elecraft is capable
of producing receivers that top the charts over at Sherwood engineering but
still cost only what their competitors' "entry level" rigs do. 

I don't think the Icom leopard is necessarily going to change its spots with
the 7300, it never has in the past.  Either the price is going to be really
high or the performance mediocre (or maybe both). I personally have always
been dismayed at how poor Icom's RX's have been even at the higher price
ranges; even my K2 runs circles around my 706MKIIG in terms of RX
performance.  

I think the highest bang/buck ratio is still held by Elecraft and I don't
see that changing for quite a while...

That's a very unfair comparison -- the 706, like the Yaesu FT100D, 
FT847, and FT897, in all their incarnations combine a lousy receiver 
with el cheapo noise generators that have no business being used on the 
air.

My experience with direct sampling radios (ANAN-100D & Flex 6500 in the
shack alongside my K3s/P3) is that their front ends are plenty robust
enough for contesting and low band dx'ing.  N5AC made some interesting

Since the 7300 uses direct sampling, it will have the same blocking dynamic
range (BDR) problem as other radios in this class, especially multi-signal
situations such as contesting. I also doubt it will beat the KX3 in
close-spaced dynamic range, unless they used a very exotic, very expensive
A-to-D converter. (Note that the only way the Flex 6700 series can achieve
good close-in dynamic range is by turning on the preamp. This overcomes the
very poor preamp-off MDS, but at an even greater cost in BDR.)

I submit that an 'entry level' rig is often a handed down or used rig.  
The 7300 is an 'economy' model direct conversion (which is not 
unattractive to some)... however...

The IC-7300 should have had VGA/HDMI output for a larger display option 
(ideally a Bluetooth link to extend the entire touch screen and a few 
knobs to an interactive tablet app, then store the rig elsewhere like 
under the back seat, trunk etc.).  When a rig has a video display (not 
just LED readouts) it is simply ignorant to ignore video output as a 
standard feature (or as an available option), even on an entry level 
rig.  Not everyone wants a tiny touch display that may quickly get 
covered in finger goo (mobile/portable environment is not nearly as 
clean as the average shack) and having a larger display makes it easier 
to actually see the scope etc. in a more comfortable operating position, 
no hunching down to see it on the table.

However, I will be watching it as a potential RV rig (where I don't 
expect stellar performance); my other choices (in order) are a basic 
K3/100 with tuner (less 'stuff' when compared to the home rig, secured 
during travel), the KW TS-480HX (already have one in the truck) and the 
KX3 with an amp and the '7300 (huge cost differences).  Even the 7300 
minimal scope is better than no P(X)3 so it's a matter of how much to 
spend to make a basic RV station. All can be managed by an external 
computer, mentioned only to dismiss it entirely in discussion.  In the 
RV world, size (storage space or station space) and weight (load limits, 
fuel use) are HUGE factors.  A case of oranges and grapefruit perhaps (a 
potential lemon tossed in)?

Further, the KW line and Elecraft menu/command structure is so simple, 
logical and similar, I don't have to 'switch gears' to use either; the 
Icom, is um, different.  Always has been, I've never 'liked' it, I just 
learned to adapt when I used one (Field day typically).

Well, that would be my point, of course :). With Elecraft rigs, "you get what
you pay for" means a completely different thing than it does with Elecraft's
competitors. IMHO, of course.

And honestly, now that I've put the new synth in my K3 and just bought a
K3S, I don't think there's a better performing pair of rigs I could buy at
any cost, really. And they even work well /P with a battery and my
buddipole, which is all the operating I'm able to do these days. So I kind
of don't really even have a choice in the matter, even if they weren't
already the best RX's you could buy....

I have had similar experiences.  After a complete power down and later
power up, the KX3 does not know the KXPA100 amp is ready even after both
are powered on, which then requires entering the menu and returning the
right PA setting.  Reminiscent of the pre-fix days when turning on a K3
before applying power to the KAT500 would freeze the K3.

Does anyone know if there is a preferred power-up or power-down sequence
for the KX3 / KPA100 / that would avoid having to do that reset?  I think
this came up on the reflector once before but I don?t recall . . .

On the other question, about the KX3 and the PX3, there is an option in
the PX3 that would bypass its power switch and have it come on as soon as
power is supplied, and a second option that does the same but leaves the
power switch operable so long as the power isn?t removed.  Requires moving
a jumper -  p.22 of the Manual.

Ted,

I am not sure what you mean about a "complete power down".  If that 
involves turning off the power supply, then I cannot comment because my 
power supply is turned on 24/7.  I have never seen that situation.  My 
KX3 turns on the KXPA100, no intervention required.

Based on my experience, I would think that turning on the power supply 
first, then powering the KXPA100 and lastly the KX3 might prevent the 
problem.  In other words, if the KXPA100 is not powered on first, the 
KX3 will not recognize it when powered on, and may turn the PA Mode 
parameter to OFF.

As I said, I never touch the KXPA100, it turns on/off with the power to 
the KX3.

I have no answer on your PX3 question.

Don W3FPR

I will keep my KX3 then.  I like the idea it is 1/5th the size!  All the other good features are bonus cream on top.

But, since Icom America Headquarters is just a few blocks from my house (probably 15 minutes walking time) I will wait for a bit and then wander down to see if they have the 7300 alive and hooked up in their ham-shack.  They have a nice Stepper up about 75 feet for an antenna so it will be a nice test.  Usually though, it takes a while for them to get new equipment in their shack.  It took six months for the first 7800 to show up there after the first availability from retailers.

Hello JOe,
Checking from websites in JA, street price in Akihabara, Tokyo is far cheaper for IC7300.

If one is not a backpacker or wants 100W output - perhaps for mobile
work - the "traditional knob" interface, built in tuner, support for
the AH-3/AH-4 tuners at the antenna, 100W, etc. make the IC-7300 quite
interesting.? IIRC, the 7300 will do PSK31/RTTY with an internal
decoder and attached keyboard.? Icom's claimed RMDDR and phase noise
specifications will, if accurate, put the 7300 in the top echelon of
Sherwood's test results.? The 7300 has what appears to be relatively
"tight" preselectors which should minimize the "composite signal level"
ADC overload (much more than the Flex-6300 with no preselectors) and
those with limited antennas (e.g. mobile, compromise wires, etc.) are
even less likely to see the strong signal composite overload than
someone with big antennas high in the air.

My disappointment is that after claiming the 7300 would be an "entry
level" rig, the price is well above that of Icom's other entry level
rigs (the IC-718 or IC-7100).? At the announced price, the 7300 should
have included a RX ANT Out/RX ANT In "loop," support for a second
antenna, and a video output to feed a larger display.

At its size and power level the 7300 is not the "backpacker's special"
nor was it intended to be.? To make that comparison is patently unfair.

Subject: [Elecraft] KXPA100 and KX3 - strange behavior.\
Message-ID: <021701d1741d$37e96010$a7bc2030$@comcast.net>

I just returned from running my KX3, PX3, and KXPA100 portable.  I setup the
three units at my home QTH anticipating a sked to Rarotonga, at 02Z and find
that my KPXA has the swr indictor blinking, and when I try to tune, it stays
at 1.6-1 and does not release the transmit, the red led remains on.  I am
not sure it is tuning at all.  I made the mistake of trying to tune with the
antenna connection not connected to my KX3.  It gave an SWR of 24-1 and
tried to tune, then I discovered my problem and turned things off.  I have
mistakenly tried to tune with an antenna unplugged with no problems.  Both
antennas were attached to the KXPA when I tried the initial tune.  When I
connected the RF IN to my KX3, then I had this problem.

 

Any clues to what is going on?  The SWR indicator continues to flash with no
RF to the AMP.

 

Thanks,

 

Terry

Wayne,
     If you remember Dayton, you saw some of what we do with the K line. 
If you really want to know how strong the KX3 and K3 address ham radio 
requirements, you really need  to see our little group contest in the 
low and high power categories and then switch to operate Field Day 3A 
QRP.

     The majority of our group belong to the Potomac Valley Radio Club. 
What that means is there are at least a few of us who are serious; I 
can't be called serious as I never learned to touch type. My point is 
there is no other radio that I am aware of that can compete with the K 
line when you look at what beginning through advanced hams need/want.

     Let me change theme. I found it interesting that Icom said that they 
were using direct sampling for the 7300. That statement contradicts what 
they appear to really be doing. It appears to me that they are 
digitizing a 36 KHz IF vice digitizing the spectrum as the Flex does. 
Flex runs a 200 MHz 16 bit A/D that they use to produce the data on 
which they operate. What I don't know from Icom is are they using a 16 
or 24 bit A/D as you guys do; I prefer the 24 bit architecture. And, I 
particularly prefer the KX3 architecture as you allowed me access the 
I&Q data so I could play off the radio, something my friends with K3s 
would have liked to have.

Vy 73,
Barry
K3NDM

I too am a little confused as to "Complete power down".  If you do not shut
the KX3/KXPA100 down using the power off buttons ( band /autotune) but shut
down the external power source, the KX3 senses that and switches to internal
bat if installed.  This switches the power out to below 10W which sets PA
off.  When the KX3 is finally shut down it remembers it's last state and
comes up as PA off.  I have both KX3 and KXPA100 on same supply.  I turn on
supply then then KX3 which after boot sequence turns on KXPA100.  Not sure
if this will help, but I have seen what you are experiencing when the power
is accidentally shut down before shutting of KX3.

N5AC is "talking his book" and totally out of touch with reality.
While he claims the issue of ADC overload is blown out of proportion
and cites mathematical models to support his claim, it doesn't always
work that way in the real world.  Put another way, the real world is
not always "neat" with a bunch of similar level signals across a wide
spectrum.  Try copying a -130 dBm signal among multiple -30 to -50 dBm
(S9+20 to S9+40 dB) amateur signals on 160 with a dozen AM signals also
present at -30 dBm to 0 dBm at the receiver input.  See the spectrum
analyzer plot from K8AQC showing fifteen AM signals stronger than -40
dBm and *five* stronger than -10 dBm: 
<http://cliftonlaboratories.com/z10020_am_medium_wave_band_reject_filter.htm>. 
  I doubt N5AC can show
that a Flex 6300, 6500, or even a 6700 (without the optional second
SCU) can *simultaneously* provide -130 dBm sensitivity and +100 dB
2 KHz IMDDR3 on 160 meters while running a second slice receiver
(panadapter) on 80 or 40 meters under those conditions in tests
certified by independent experts - yet those are the very conditions
he claims mathematically can't happen.

NC0B (in personal e-mail) has reported significant symptoms of ADC
overload with a non-Flex direct sampling SDR with a 250 MHz ADC on 160
meters at his *rural* Colorado location.  ARRL Labs shows the same
trade off between sensitivity and IMDDR3 with the both the Flex 6300
and Flex 6700 in the April 2015 QST review 
<http://www.arrl.org/files/file/protected/Group/Members/ProductReview/PROD_REV_0415.pdf>. 
  The
review shows a substantial reduction in sensitivity with the preamp
turned off and a substantial fall-off in dynamic range with the preamp
turned on.  ARRL does not even publish dynamic range at 2 KHz with the
highest gain preamp even though their measurements are made with only
two signals - not a dozen or more close in signals at the same high
level.

Sherwood shows the tradeoff between sensitivity and dynamic range in
his "Receiver Test Data" table <http://www.sherweng.com/table.html>.
It is most clear in the 100 KHz Blocking values where the Flex 6700
shows "A/D Limit varies with Preamp Gain" ... in other words, when the
preamp is on (as required for the -135 dBm sensitivity), the Blocking
values fall apart (vs. > 150 dB 100 KHz blocking range for the K3S).

The issue of ADC overload can't be simply dismissed by hand waving as
N5AC and others would like.  The current technology is not robust
enough to simultaneously provide -145 dB MDS, 100 dB+ 2 KHz IMDDR3
and 130 dB+ Blocking Dynamic range as the case for the K3S, K3 and
KX3.

ADC technology - instantaneous peak voltage handling - needs to improve
another 10 to 20 dB before direct sampling can be said to be completely
reliable in all conditions.  It may "work fine" in many locations where
antenna selectivity, external bandpass filters and even propagation
protect the ADC from overload.  However, direct sampling does not work
well in the presence of multiple, very strong, close in signals as
shown by both ARRL and NC0B testing - no matter how much the proponents
of direct sampling would like to make you believe.

Problem solved, and I don't know why.  I posted a few minutes ago saying the
blinking indicator was the PWR not SWR.  I looked at all my connections,
they were fine.  Pushed in all the connectors and all were tight.  I ran the
utility program for KXPA100 and no faults were found.  I then checked all
connections again, and everything now works.  I am puzzled, but I wanted to
get back to the group so no one else tried to help me now that the problem
is solved.  If someone has had a similar experience, I would like to know
what might have been going on.

See page 28 of PX3 manual there is an internal jumper that can be set to

Hi,

I've been operating with an OpenHPSDR Hermes driving a KXPA100 for quite

power operation. My plan is to drive the KPA500 from the KXPA100. I know 
that others have done this, but I haven't seen many details.

Since I have an early KXPA100 (Serial #302), it doesn't have the extra 
PTT protection, but I believe that is not a problem with the KPA500, 
since it uses a 5V keying circuit. So I plan to "Y" the PTT connection 
from the Hermes (actually there's some custom mods to provide a little 
more protection for the Hermes on the PTT line, and was also a required 
change to properly key the KXPA100) that currently goes to the KXPA100 
and connect that also to the KAT500. Then I will connect the PTT out 
from the KAT500 to the PTT in on the KPA500. I'll operate the built-in 
KXAT100 in bypass mode when operating with the KPA500.  Are there any 
potential issues I should be looking for? Any timing adjustments that 
can be made?

I know I'll have to do some calibration with the HPSDR software to make 
sure that I don't drive the KXPA100 beyond 30-40 watts when it is 
driving the KPA500. I don't have any way of doing anything with the ALC 
output from the KPA500, so I just need to make sure I don't get it to 
that point.

Eventually I plan to do some better software integration to take better 
advantage of the band switching support, but I've meant to do that for 
some time with the KXPA100 and haven't gotten around to it (so much 
software to write, so little time!). So meanwhile I'll be operating with 
a fairly basic connection setup.

Some questions:

1) Since I don't have a K3, I currently have no need for the AUX 
connector that would normally go between the K3 and the KAT500. Is there 
any advantage/reason to connect an AUX cable between the KAT500 and the 
KPA500? If the KAT500 is basically just looking at the signals from the 
K3 without ever driving anything for the connection to the KPA500, then 
this wouldn't make sense. But if there is any active info being passed, 
perhaps it would make sense? For example, while the KAT500 is tuning it 
can drop PTT to the KPA500, in which case the KPA500 is probably not 
determining the transmit frequency, whereas the KAT500 is looking at 
that. It could tell the KPA500 the correct band rather than having the 
KPA500 determine that by itself. Probably not that important, but 
perhaps I'm missing something.

2) Is there any indication in the KPA500 LCD screen when the ALC is 
triggered? How about the KPA500 utility? I haven't seen anything in the 
documentation, but perhaps I missed that.

3) I ordered both the 120V power cord/fuses and the 240V power 
cord/fuses.  I'm going to start with 120V operation, but I can wire the 
study (my "shack") with a 240V outlet if necessary.
I'm not even sure I can currently dedicate a 120V circuit to the amp, so 
I might have to move to 240V fairly quickly (If I'm going to wire a new 
circuit, might as well be a 240V circuit). For
those running their KPA500's on 120V how well has that worked for you?

4) Anything else that I might have missed? I'm especially interested in 
any operating procedure tips from those who are running with a KXPA100 
driving their KPA500.

5) I read about some earlier issues with the KAT500/KPA500 when tuning, 
i.e. the KPA500 would fault during the tune in some cases. I believe 
that has been fixed in firmware, i.e. I haven't seen any recent reports 
related to this. Can I assume this issue is no longer present?

Local telecommunication authority is considering 60m operation for the hams in VR2. For output power of 15W PEP, using a dipole for NVIS, what would be the likely usual communication range 7/24 round the clock? ?100km radius?
Any advice will be appreciated and thanks for the band width here.

Dear Elecrafters

I am the fortunate owner of a K3 100 with subreceiver and 13kHz, 2.8kHz,
1.8kHz, 400Hz and 200Hz roofing filters.

My wish is to use Skimmer to monitor as much as possible from 3.500 to
3.525kHz for CW signals. But I am not ready for the economic and practical
challenges of using P3 or a SDR radio. 

My plan was to use my 13kHz FM filter to receive CW but that seems not to be
"allowed". That is what K3 Util tells me when I try to enable the 13kHz for
CW reception. 

Any suggestions?

Or is it just plain impossible?

IC-7300 may be a radio between IC-7100 or IC-7410. Its price probably will
fall to $1000 like of 7100. Ultimately direct SDR is less expensive
technology.

Regarding strong-signal handling, sometimes I set SDR-IQ (14 bit) as skimmer
in 160m contests. Despite zillions of strong signals, SDR-IQ finds DX buried
in noise that P3 barely can see. 

 $150 SDR-Play (0.1-2000MHz, 12 bit) shows capabilities and complexities of
SDR. It consist of wide bandpass filters followed by a conversion unit
followed by SDR machinery. One can choose zero or nonzero IFs.  On HF large
differences in strong-signal handling between the two. 2m reception better
than IC-7000. 

A competition keeps progress alive.

Ignacy, NO9E

Hard to compare other modern Icom transceivers to the 706 which had 
about the worse rx of any of their rigs in the past 30 years.  It was, 
after all, a mobile rig designed several decades ago.  The IC-7300 does 
represent an interesting step forward in technology.

Large, touch-enabled, menu driven color screens are the future.  It 
eliminates a lot of physical controls that add considerably to the final 
cost.  The actual specifications aren't always the final measure of 
cost/benefit.  Usability and accessibility are very important factors as 
well.

If I'm going to engage in serious contesting, the K3 is the obvious 
choice.  For everyday casual operating, I can have many enjoyable 
contacts with one of my ancient Swan Cygnet 270B's.  It's not always A 
VS: B.  Considering the features of the IC-7300 within it's price range 
- it's got a lot to offer.

A K3s/100 and a P3 (to match the features of the IC-7300) is vastly more 
expensive.  So there is no fair comparison between the two.

A K3s with the same set of features as the IC-7300 will cost $4,269.75, 
whereas the IC-7300 announced price (DXEngineering) is $1,499.00.  So 
that high-performance receiver essentially costs $2,770.75.

If you have spent serious time with an IC-7600, IC-7700, or IC-7800, you 
would absolutely NOT say their performance is mediocre.

Excellent points, Doug. Still, the bang/buck ratio belongs to Elecraft,
especially at the high end, in my view. For example, if you took that $4,269
on the K line, added approx $2000 more to it and put it into an IC 7700,
say, you come out far behind performance-wise and 2 grand poorer too. So I
don't see how one really comes out ahead in that case.

I don't doubt at all that Icom's high end rigs are good rigs with good
performance, but the K3 and K3S at the core of the Elecraft investment still
far outperform them for less money. For me anyway, Icoms offer nothing
comparable to the K line at the upper end of the $ range, not even close.

As for the 7300, though, I think you make an excellent point. It does offer
a definite draw for the market you describe...

If you look at test data from both Sherwood and ARRL, I don't believe
you can consider any of the Icom rigs (ProIII, 7600, 7700, 7800) to
be "high performance" (I'm holding judgement until I see test data
on the 7851).  In all cases, phase noise and 2 KHz IMDDR3 are barely
adequate with 2 KHz IMDDR3 between 70 and 80 dB and phase noise in
the 125 - 130 dBc/Hz range 10 KHz from carrier.

Those numbers put Icom's top of the line rigs behind well known "High
performance" rigs like the Flex-1500 and Yaesu FTdx3000!

In the mid to later 60's while "vacationing" in SE Asia, most of our 
in-country net frequencies were in the 5 MHz range.  Generally, it was 
100W [KWM2A] to a low dipole [GRA-4].  From Vietnam, we had no problem 
with stations in the Philippines, Thailand or anywhere in-country. 
That's about 8 dB more than your 15W, a tad over 1 S-unit.

Having CW and Data [<2.8 KHz BW] as well as USB is probably more 
important than power.  5 MHz sometimes went long after sunset but still 
worked.

oh, I totally agree - even my K2 nips at the heels of a 7700 and probably
even a 7800, especially in a pileup. I just didn't want to bury Doug's
point, which I think is a good one. A rig purchase is often a compromise,
where it's often ok to sacrifice one feature set for another to suit one's
budget or intended use of the rig. Something like the 7300 can fill a niche,
as Doug describes so I think he's totally right on that point.

OTOH, it's hard not to be biased once you get your first Elecraft rig, or
two... your opinions very quickly converge away from El's competitors once
you start putting them on the air, etc. and those rigs become three... and
then 4..... :).

The observation I would make on this is that the poor performing Icoms 
were good enough to capture all 3 of the top positions in the recent 
WRTC. IIRC there was one Elecraft and 5 Icoms used by the top 3 teams.

I don't want to read too much into that, op skills play heavily in the 
results. And luck plays a role as well. But nonetheless, even though 
the 'numbers' of the Icoms are not all that good, they appear to be 
'good enough'.

They do have too much TX noise. But then nearly all rigs have too much 
TX noise.

My view is that the top-of-the-line rigs are serious overkill for 
nearly all hams.

Even the lowly FT-857, which is no ones idea of a 'contest rig', did 
surprisingly well in the hands of two very good ops. This was back in 
the WRTC in 2010. Their pair of K3's were wiped out by lightning. They 
lost an hour of op time while swapping rigs but still finished about 
35th out of 50. At the end of that lost hour they were dead last, but 
then climbed back up the list. So I think the evidence indicates that 
even under the demanding condx of a contest a lot of rigs are good 
enough to be competitive. Guys should spend less on rigs and more on 
antennas. Or maybe spend that extra $$$ on beer and women . . .

ICOM provided rigs at no cost to those who couldn't or didn't want to 
bring their own rig to WRTC. Elecraft rigs were owned by the 
participants, and were about 2/3 of the rigs in use. Also, many 
participants don't care (or don't know) if their rig is dirty on CW, and 
those ICOM rigs are (although not as nasty as the Yaesu rigs).

Can the K3 be controlled using RS-232 via the RJ-45 while simultaneously 
using the USB connection for it's sound card functions?  I didn't find a 
difinitive answer in the books.  If it can do this, I won't have to 
re-configure all my software and it would save me a bunch of time - LOL.

Message-ID: <D7DDDC6C-C60D-44AB-914D-19AA074B015F@me.com>

I recently built and have installed a T1 tuner in combination with an OmniaSDR QRPp radio. The radio fully supports the T1, inasmuch as it sends band change and tune data to the T1 via the ?remote? connection on the T1. So far mine has been working very well, although my antenna is fairly close to being resonant.

The T1 owner?s manual notes that band information is stored in EEPROM. My question is how many memory positions are there? Only one per band, or multiples, like in the other Elecraft auto-tuners? Haven?t found that documented in the manual?.

Tnx, Jim / W6JHB

Yes.  Set the RS232 menu item to the speed you want.  If it is not in 
USB in that menu, then it is using the regular RS232 port.

To use the USB audio for Tx, be sure no cable is plugged into the analog 
LINE IN jack.

Spend the $20 for a generic SDR, do the direct sampling mod on it, then run
HDSDR in windows.
Connect the antenna jack to the IF output on your K3 if you have the option
for that. 
Receive center freq on the SDR 8.215MHz, 
You'll see everything the IF on the RIG is seeing. 

To configure filter use the K3 Utility to set which modes in which it's
permitted to be used.

Dear Elecrafters

I am the fortunate owner of a K3 100 with subreceiver and 13kHz, 2.8kHz,
1.8kHz, 400Hz and 200Hz roofing filters.

My wish is to use Skimmer to monitor as much as possible from 3.500 to
3.525kHz for CW signals. But I am not ready for the economic and practical
challenges of using P3 or a SDR radio. 

My plan was to use my 13kHz FM filter to receive CW but that seems not to be
"allowed". That is what K3 Util tells me when I try to enable the 13kHz for
CW reception. 

Any suggestions?

Or is it just plain impossible?

Thanks Lyle,
I thought that was the way it should work, but I couldn't find it in the 
books (not sure if I overlooked it or might be something that needs to 
be added).  Anyway that saves me a whole lot of shack re-wiring and I'll 
be able to run two instances of MMTTY for SPLIT copy of the 2nd RX.

Also gets the HUGE HAL ST-8000A off the desk and frees up a bunch of 
room on the monitor shelf.

If I understand what you mean to ask the answer is yes.
You can do CAT control AND audio in/out via K3S USB at the same time. 
Don't connect anything to the DB connector. It is NOT a standard serial
connection

Yes, and a Flex 6700's ADC evidently didn't crumble in the big signal
jungle on topband and garnered #1 USA (assisted/unlimited) in the recent CQ
WW 160M CW contest.

I haven't used the band but I would expect it would have characteristics 
similar to the 80m and 40m band. Those bands are generally short range 
during local daylight hours and can be around the world after sunset.

Please read carefully. I am wanting to get a Yamaha CM500 and add a PTT
switch. Do not recommend a foot switch I am wheelchair bound and have no
way of using my feet. I am looking for a button PTT switch and not a
trigger switch. When I searched the internet the one I saw was "no longer
in production for new orders" due to health issues. I may consider building
my own. The Yamaha CM500 and PTT switch will be used with my K3S. I can not
use VOX due to the noise level in my shack (kids, grandchild, wife and
dog). If you would like email me the link directly. Thanks in advance.

I sometimes use my straight key as a PTT switch.

I use the Elecraft MH2 microphone as a hand operated push to 
talk switch with my Yamaha CM500. The CM500 is plugged into the 
back microphone socket and the MH2 is plugged into the front 
socket. The MIC SEL menu option is set to rP.L bIAS. Works like 
a charm.

Steven, I've used the W2ENY adaptors. He also sells a handheld PTT switch/cable to plug into the PTT connector on the adaptor. I use it with my CM500 on a non-Electaft radio. Other switch types could be plugged into the connector.

Another option would be to fabricate a small ?dongle? that has 3-conductor mini jacks (3.5mm) on the ends, using a very small project box or even a mini Altoids tin.  Mount on the side of the box  any of the literally hundreds of momentary push button switches on the market (allelectronics.com currently lists 45 of various size, shapes and colors).  Wire the mike leads straight through from one jack to the other, and route the switch lead through the PTT switch. Plug the Yamana headset into one side of the dongle; use a "stereo extension? cable to connect the other side of the dongle to your rig. Put a strip of ?hook? Velcro on the bottom of the dongle and a strip of ?loop? Velcro on a convenient spot on the arm or table of your wheelchair. With this setup, you could move your wheelchair quite a distance from the rig, if desired.  Simply remove the dongle from your wheel chair when not operating. If you don?t want to attach Velcro to your wheelchair, you might glue a small magnet to the project box. Or mount the ?dongle? on the desk surface of your station. 

Hmmm, I like this idea enough to try it myself, even though I?m not in a wheel chair. I have everything I need in the junk box.

Steven,

The hard part is finding a handheld switch that you are comfortable 
with.  As someone mentioned, if you have another microphone with a PTT 
switch, plug that into the front panel and plug the CM500 into the 
rear.  When the rear panel microphone is selected, the PTT button on the 
microphone will work (but the mic will not).

The other alternative is to find a cable mounted switch that you are 
comfortable with and solder an RCA Plug to the end of the cable - plug 
it into the rear panel PTT jack.

73,
Don W3FPR

find an old desk mic and remove the mic.

I am in the process of deigning and building a simple PTT switch that is basically the base of a desk mic without the mic.  When I get it finished, I will post it here for comment.  It will be a  3D printed box and some switches and a 1/8 plug for a cable.    I made one from thin plywood using a couple of relay contacts back in 2008 and my club and I have used it ever since fopr thousands of contacts both indoors and out.

I haven't used the band but I would expect it would have characteristics 
similar to the 80m and 40m band. Those bands are generally short range 
during local daylight hours and can be around the world after sunset.

The justification here in the USA for access to 60 meters was that emergency nets (particularly hurricane nets in the American southeast) found their range too short on 75 meters during the day and the typical 40 meter short-skip range was too long for communications in the 50 to 100 mile range.

Daytime range on 75 is limited by ionization of the lower atmosphere by the sun's radiation, which absorbs RF. 60 meters has significantly less ionization loss and, as you know 40 meters has even less, which allows stable communications in the 100 to 500 mile skip zone in the daytime. Overnight, that skip steadily increases as lower atmospheric ionization fades without the sun's radiation on 40. However, that ionization helps maintain a short skip range throughout most of the night on 60 meters.

Of course it all varies according to solar activity.

Dear Elecrafters,
Local telecommunication authority is considering 60m operation for the hams in VR2. For output power of 15W PEP, using a dipole for NVIS, what would be the likely usual communication range 7/24 round the clock?  100km radius?
Any advice will be appreciated and thanks for the band width here.

Joe seems to concede that the Icoms are "poor performing", but that somehow 
they took the top 3 positions in the WRTC.  So what does that mean?  It 
seems to suggest that the dirtier your signal is the better you will do!!! 
I would agree that a dirty signal does tend to get your attention!!!  At the 
same time, the fact that there was only one Elecraft radio in use certainly 
assured the fact that Icoms would finish high.   I can also see why the 
Elecraft may not have finished in the top 3, since it really is not 
designed, with all the glitz and 500 knobs, to be a contest radio.  Rather, 
it is designed to be a modest sized, but highly competent radio!  That may 
not dovetail with what contesters are looking for.  However, when it comes 
to "nailing down" a difficult contact, one at a time, I'll put the K3 up 
against just about any radio.

The obsession with contests is a concern to me.  During those events I 
constantly hear signals that are obviously the result of over driving, etc. 
Some folks seem to be willing to sacrifice anything in order to just be 
"heard" better than the next guy.  They will absolutely squeeze the very 
last watt possible out of their equipment even though they know (and have 
been warned) that running equipment that close to maximum increases the 
probability that signal quality will deteriorate, and very probably outside 
required specifications.  It just seems to me that this is a subversive way 
of cheating!

Admittedly, not all of this is the fault of the operator.  Equipment 
manufacturers have increasingly ignored the importance of signal purity. 
Still, if you take a piece of equipment that is known to be deficient, and 
then run it at levels that accentuate the problem, I think you lose your 
innocence.

Even the K3 had a potential problem.  At one time you could run a stock K3 
at more than 100 watts, thus increasing significantly the odds of 
transmitting a dirty signal.  Elecraft dialed that capability back through 
firmware.  I may be kidding myself, but my rule of thumb is to never run 
anything at more than 90% of it's rated capability.  Maybe that's not 
dialing back enough, but it is bound to be better than what I could be 
doing.

I use 60m occasionally and I don't think it is "reliable" 24/7. 
especially for only a 100km radius.   60 tends to go long in the 
evenings.  It works well as one tool in a toolbox with several tools. 
But I think it shines for longer distances than 100km.   As others have 
said, it's better than 80 during the daytime and better than 40 in the 
evenings for short distance.  But don't be surprised if 400 miles (600 
km) is the closest you can work some evenings.

I would also suggest higher power to help with poor propagation and/or 
summer QRN.

I don't think you understand what the WRTC is. Do some research and 
you will find that the kind of dirty TX you are talking about would 
not be tolerated in this event.

In a general contest this may be a valid point. Yaesu was known for 
years for having loud key clicks on the FT-1000. And they did win a 
lot of contests. But that is not applicable to the WRTC, which is a 
tightly regulated and monitored event.

Me too. In find that the "NEW QSK" is the same as the "OLD QSK" with a slight delay. It's better to turn down the RF gain if you get too much "popping" sound in your audio.

Subject: [Elecraft] K3S USB port
Message-ID: <em1b36a967-be22-43cc-9851-ec91bd3fba95@jimsdesktop-pc>

First off, this is NOT a complaint, merely an observation. and in my 
opinion, worthy of note for the programmers to check out.  I didn't 
think this was supposed to work but it seems to work quite well, at 
least in my case.

I am using serial RS-232 with the following cabling - Desktop COM-1 to 
P3, P3 to K3S using the DE-9 to RJ-45 adapter (not the two headed cable 
between the P3 and K3S) from my desktop computer.  I am also running the 
USB port cable to a Raspberry Pi model 2, single board Linux computer 
with the K3S configured as the USB Audio Codecs AND serial comms using 
/devttyUSB0 for rig control with VOX for PTT, in FLDIGI on the Raspberry 
Pi.  All serial speeds are set to 38.4K baud.

The P3 still indicates the K3S frequency as I tune (slight delay), 
FLDIGI on the Pi 2 indicates the K3S frequency as I tune.  TX/RX audio 
from and to FLDIGI on the Pi 2 work properly, and I am able to make 
contacts with no problem as well.  I can also tune the K3S using 
FLDIGI's frequency control.  I am using N3FJP's AC Log program on the 
big desktop computer for logging and it also displays the proper 
band/mode from the K3S.  It also follows frequency changes made by the 
FLDIGI program on the Pi 2.  I did not attempt to configure DTR or RTS 
for push to talk as VOX works so well.

It was my original understanding that you couldn't do this (RS-232 using 
the RJ-45 jack AND the USB port simultaneously).  I DO have the K3S 
RS-232 configured to USB in the menu.  The difference may be due to the 
fact that I'm using two separate computers here with both 
talking/listening to the K3S.

I'm running FW version UC 5.46, DSP 1 and 2  version 2.86, FL version 
1.25 on the K3S and MCU 1.57, SVGA 1.31 and the FPGA's 1.04 in the P3.

DISCLAIMER: If anyone else tries this, make sure to SAVE YOUR 
CONFIGURATION prior to making any changes so you won't forget what they 
were before and if something messes up you can re-load the previous 
version.

Nope. It's a switch-mode power supply, the sort of thing that powers 
almost anything we buy nowadays -- it's in the wall warts for all sorts 
equipment, battery chargers, computers, even built into home electronics.

Further notes on the subject:
I just thought of the possibility that FLDIGI on the Raspberry Pi 2 is 
echoing the K3S data on /devttyUSB0 and that's possibly how the P3 is 
getting the frequency changes.

Yup, I just closed FLDIGI on the Pi 2 and now the P3 no longer gets the 
frequency data from the K3S as I have it configured.  Turns out 
everything was working as it should and the anomaly was caused by the 
running program on the 2nd computer.  Might prove useful in some cases 
but I can see it may not be reliable.

Subject: [Elecraft] K3s using RS232 v USB?
Message-ID: <56D88CEB.7060601@4email.net>


Am in the process of setting up K3s and would like advice on the pro/con
of using RS232 via interface (mKII) to computer or simply USB port to
computer. One pro is obvious to me, such as eliminating the Hydra cable
between my microHam MKII and rig. BTW, the mKII is great piece of "kit"
which I have had for over 8 years, first on Orion II then K3 #250. Never
an issue, always worked perfectly...kinda like an autopilot, one never
thinks about what it does, until it fails.

As a heavy equipment operator, B777/787 (instructor pilot) the A/P is
engaged after take off and the jet flies itself (via computer inputs) to
touchdown in LU land 9 hours later; a total A/P failure has never
happened in those aircraft, what with redundancy, but if it did, it
would be like 9 hours of operating a dxpedition with paper log and bug.

As CX7TT/CW7T, made over 30k Qs in 10 years on all modes but mostly cw
and RTTY. Even did 1st moon bounce with W7GJ from MT to CX. So now you
have an idea of what and how I operate...throw in a little PSK and WSJT.

Now, I have looked for info on Nabble so as to not invent the wheel, the
K3s manual and Fred, KE7X, excellent K3s/P3 manual, Ch 10 KIO3B which
shows the many variations to configure and setup. I am not an EE or
electronics technician, simply an appliance operator, so I need you guys
to keep it simple!

I would like to know exactly what would be sacrificed by the convenience
of using the USB to computer vs an external interface. So what are the
con(s)?

Thanks for reading.

Hi Jim,
It's my understanding that the RS232 port is live for serial data out from the K3 (RXD) but not for serial data in (TXD).
Have you tried to use the K3 Utility with your set up? That would require bidirectional serial data and in theory shouldn't work.
Cheers,
Fred KE7X

The P3 still indicates the K3S frequency as I tune (slight delay),
FLDIGI on the Pi 2 indicates the K3S frequency as I tune.  TX/RX audio
from and to FLDIGI on the Pi 2 work properly, and I am able to make
contacts with no problem as well.  I can also tune the K3S using
FLDIGI's frequency control.  I am using N3FJP's AC Log program on the
big desktop computer for logging and it also displays the proper
band/mode from the K3S.  It also follows frequency changes made by the
FLDIGI program on the Pi 2.  I did not attempt to configure DTR or RTS
for push to talk as VOX works so well.

It was my original understanding that you couldn't do this (RS-232 using
the RJ-45 jack AND the USB port simultaneously).  I DO have the K3S
RS-232 configured to USB in the menu.  The difference may be due to the
fact that I'm using two separate computers here with both
talking/listening to the K3S.

I'm running FW version UC 5.46, DSP 1 and 2  version 2.86, FL version
1.25 on the K3S and MCU 1.57, SVGA 1.31 and the FPGA's 1.04 in the P3.

DISCLAIMER: If anyone else tries this, make sure to SAVE YOUR
CONFIGURATION prior to making any changes so you won't forget what they
were before and if something messes up you can re-load the previous
version.

On the K3, the serial port is perfect - for use with either a real 
serial port or a USB adapter.  I prefer going direct to a real serial 
port, without any adapter.

Is the USB in the K3S merely a built-in adapter? That would eliminate a 
problem some ops have had with external adapters (Prolific??).

The only con, really, is being tied to an RF-hash producing, frantic,
freezing, crashing computer if you want to operate your radio. I'm a SW
developer and I have to fight those things all day, every day so that's the
indelible image in my mind when trying to mix my Mac with Ham Radio - so I
tend to try to avoid having to use a computer for my radio ops if I can help
it. Just give me a Vibroplex and a notebook&pen and I'm happy.

Otherwise, there are no negatives to using the USB support over the RS232
that I can see. I believe both Windows and MacOS already have driver support
for the internals inside the K3S, so the basics like using the K3 utility
and using its audio devices within applications with sound support is pretty
much plug-and-play. 

I believe the K3 utility worked out-of-the-box on my Mac with my K3S when I
checked it over a few weeks ago.

I too have this all over the place on the lower bands (80 and 40 mostly) at
home. I've always thought it was noise from the Faraday cage my indoor
antennas have to be inside of causing it. When I'm /P in the hills outside
of of town I never hear this...

QRN, not QRM.  I can't see what the span is on your panadapter, but it 
has all the characteristics of an SMPS ... they're all over the place, 
you're probably seeing more than one.

When we were in CA on 5 acres in a rural area, I hosted the neighborhood 
wireless on my tower in return for free I'net at the backhaul speed [~90 
Mbps].  No problems except a few weak narrowband discrete birdies 
[clocks and LO's], and I learned where they were.

They replaced their equipment with new stuff and a new router powered by 
a Chinese RPOJ** SMPS in our equipment shed with a 24 VDC line up to the 
top of the tower resembling an 80 m Inv-L.  Looked just like your 
picture with a wide span on the P3, only MUCH stronger ... in the -70 
dBm range on 80, a bit weaker on 40 and 20.  Drifted slowly back and forth.

Since they had a number of neighbors as paying customers and really 
coveted the space at the top of the tower, I told them I'd wind chokes 
according to the "K9YC Recipe," and watch them install them.  Otherwise 
they could put in a "real" linear power supply.  The chokes did the 
trick.  If you can find the offending supply(s) which may be nothing 
more than wall warts, you might be able to choke the noise out.

Tom,

The only 'cons' that I can think of is the computer OS support for the 
device in the K3S (which really is an internal USB to RS-232 adapter).
It will work just as well and likely better than an external USB to 
serial adapter.
Support for USB to serial adapters was a bit 'flaky' back in 2008 when 
the K3 was announced, but as time has gone by, I have found USB devices 
are fully supported by most computers.

Of course, if the computer has real RS-232 ports, those are usually 
independent of OS support issues - all OS variations I know about 
support the RS-232 port directly - even if the computer does not have an 
RS-232 port connection.

Hi Fred,
Not the K3 utility, but I did have the P3 utility running simultaneously 
for a time and it seemed to work just fine.  It connected and pulled in 
the FW versions I was looking for.

I did find what was giving the P3 it's information and the reason it had 
a slight update delay.  Turns out that FLDIGI on the Raspberry Pi 2 was 
echoing the serial information via /devttyUSB0 from the Pi and that was 
getting sent back to the P3 over the K3S's RS-232 on the RJ-45 
connection.  After I shut down FLDIGI on the Pi, the updates stopped and 
the P3 no longer changed the displayed frequency as the K3S was tuned.  
As soon as I restarted FLDIGI on the Pi 2, it went back to updating as 
the K3S changed frequency (with a slight delay) and almost instantly if 
the point and click controls in FLDIGI were used to change frequency.

I understand what's happening now and it seems to be only with the Pi 2 
and FLDIGI that it works this way.  Could prove to be useful, but I 
don't plan to rely on it - LOL.

Jim

Well, consulting the source [ACP131]:

QRN? "Are you troubled by static?"
QRN "I am troubled by static"

QRM? "Are you being interfered with?"
QRM "I am being interfered with"

I suppose "static" could be "interfering with you" as well as another 
station, and much of 75 m in the evening probably classes as "static" 
regardless of its source. :-)  It's seemed to me that the Q-signals 
class QRM as caused by another station and interference from everything 
else as QRN, but I'm a retired engineer not a lawyer.  Additions to the 
ICAO/ITU standards can be found at www.zerobeat.net/drakelist/missingq.html

Message-ID: <emd68d5bbb-8da2-48b0-9d8c-b1f6ffe233cc@jimsdesktop-pc>

I have for sale a Tigertronics SignaLink USB that's about a year and a 
half old.  It comes with the "Plug-N-Play" pre-wired jumper headers for 
both the Elecraft K3 and KX3 radios and also the proper interconnect 
cables for both radios.  The manual can be downloaded from the 
Tigertronics website and the drivers also if necessary.  (The Linux 
version of FLDIGI recognizes it without any hassles).  Cables for other 
radios (would require either purchase of the proper header or wiring one 
yourself to match the radio - see Tigertronics' website for further 
info.

This is a USB external sound card designed to run most if not all of the 
current digital modes almost seamlessly - provides TX/RX audio AND PTT.  
Powered through the USB cable so no external power supply is needed.  
TX/RX audio levels and PTT delay are adjustable via controls on the 
front of the unit.

I'm asking $95 shipped anywhere in the U.S. via priority mail.

Pictures available via email on request.  It's in excellent condition 
and I made a couple PSK-31 contacts with it yesterday hooked to my K3S 
to check it out.

Please contact me off list if interested and the first "I'll take it" 
gets right of first refusal - first in will be determined by date/time 
on the email.

Is there any way to easily determine if a wall wart is a SMPS?  Most probably are but are there any that are not?

I've had far fewer issues with rig control via serial than via USB. If 
there is stray RF in the shack (easy at QRO), the USB devices can 'go 
wonky' (more than a driver issue, requiring a complete shut down to 
power off, then rebooting to clear the actual USB hardware on the mobo) 
but serial chugs along.

Thanks, everyone, for weighing in. I?m armed with $95 of ferrite snap ons and chokes and two MFJ heavy duty AC filters! Saturday I plan to carefully re-design all of the AC wiring in my office/shack which is, admittedly, a hodgepodge of extension cords and power strips with at least 5 wall warts. I suspect the offending switching PS runs the brand new LG display used with the K3S SVGA. It?s a small, light little thing. Runs very hot. Most likely will be replacing it with a linear wall wart or something cleaner.
 
I found this article that explains the differences between linear and switching power supplies:  http://www.clever4hire.com/special-articles/home/ac-dc-power-supplies---using-wall-warts

Will report back.

Yes -- switch-mode supplies are a lot lighter for the same power rating. 
Another way -- tune a portable AM radio to the high end of the AM band 
and listen for noise as you hold the ferrite loopstick antenna next to 
the unit. Linear supplies will be dead quiet, SMPS units will be noisy. 
I use a Kenwood TH-F6A, which uses a ferrite loopstick in the base below 
10 MHz, and I tune it to about 2 MHz.

I have no way of verifying this, and I only date back to the 1950s as 
both ham and commercial operator. But always understood that the N (as 
in QRN) meant the interference was from 'Natural' sources and the M (as 
in QRM) meant that the interference was from 'Man-made' sources.
Guess only those who formulated the original Q-codes could tell 
us.....and they will all be SK by now!

Weigh it.  Most small wall warts are also very light.  I've got a couple 
of heavy larger ones in the junk box and the difference is hard to miss. 
  The cable from it is the radiator of course, a BC band radio tuned to 
a clear spot [preferably at the high end] will usually show a distinct 
increase in noise as you move it up the cable.

I was choking a 4 A feed to the wireless equipment and used a couple of 
3 1/2" OD [or so] toroids that N6XI gave me.  Consulting the K9YC 
recipe, I wound 12 turns of Radio Shack red-black pair on one, and as 
many turns as I could get in one layer on the other, wired them in 
series and then stacked them using zip ties.  My theory was that the one 
with lots of turns would get the 160-80 m stuff and the 12 turns would 
get 40-30-20.  They went right at the Chinese RPOJ power supply in the 
24 VDC cable.  I don't know the mix but I think probably 34 or 43, I 
think they were part of a group buy by the contest club.

My experience with the small clamp-ons has been poor, unless you get 
several turns of the cable through it, and even then I don't think 
there's enough permeability in the magnetic circuit to do much.  It's 
pretty hard to find linear wall warts these days.

I've had really good experiences with the N3FJP programs, both for contests and general logging (ACLog). They are not free--$15 for general logging, $60 for all contests and future programs), but the developer is an active ham who will answer your emails and has an active Yahoo group.  I find them much more intuitive and straightforward  than the DXLab suite. 

I would also suggest perusing the Ham Software reviews on eHam.net to get an idea of how people like the various programs out there. 

For sophisticated contest work, N1MM+ is king, but the N3FJP programs do 90% of what MM does with a much easier interface.

Subject: [Elecraft] [KX3] How to use manual notch in SSB mode
Message-ID: <1457069634297-7614894.post@n2.nabble.com>

Greetings.

You *can* use manual notch on SSB on the KX3.

Turns out that if you turn on the manual notch while in CW mode that it will
stay on if you switch to SSB without cycling thru a mode that cancels it -
such as FM or data modes.  

Here's an example of how I did it.
Starting with LSB mode:

A->B 
MODE -> CW
FC -> +0.92
BW=2.8KHz
RIT=-700Hz	This removes (my) pitch offset and opens the bandwidth to receive
LSB voice.

Now you can turn on the notch filter and adjust to remove CW RFI.
Press A/B and turn off RIT to have SSB with manual notch enabled - and CW
removed!  A/B allows me to go from CW to SSB w/o cycling thru FM, although I
could also disable FM mode.

For USB, you would need to use CWR and RIT=+700Hz.

Why this is desirable:
The auto-notch feature is great for intermittent tuneups or other (multiple)
CW signals in the SSB passband, but it is applied after the AGC, so if the
CW signal is much stronger than the voice signal, the voice signal is
suppressed even though the tone is removed - like when trying to copy an S3
voice with a S9+20 CW sitting on it.

For strong "persistent" CW QRM, using the manual notch removes the CW signal
*before* the AGC, allowing AGC to operate on the desired signal.  This notch
is at least 80dB!  The S9+20dB CW goes away, and S3 is perfectly readable!
Very cool! Especially useful if the CW signal is in the 500-1500Hz range -
making it difficult to remove with low or high pass BW adjustment and still
copy voice - you can, but it takes effort.

I tried creating a macro for this - it kinda works.

MD3;SWH20;MD1;

Works, but the macro name covers up the notch frequency display in the VFOB
area.  You *can* adjust the notch frequency even though you already in SSB
mode (if you turn the knob within the 2 sec window), but it's a blind
adjustment.  And then the macro name sticks until you do something to update
the VFOB display (like adjust BW). If you just send the commands using the
KX3 utility program, it works great, but you need a pc :\.  Perhaps there is
a macro work-around?

If I might inject a suggestion/observation:

If you are looking for 0 to 100km 100% reliable propagation it is to 
be found on 600 meters!
I ran tests all summer long in 2012 on 495-KHz CW running 100w into 
an inverted-L and was copied at 30-35 dB SNR any time we tried over a 
70mi path.  That is 6 s-units over noise!  Ran weekly sked at local 
noon all summer long (when we have 19-hours daylight).

BTW my ERP < 1w due to inefficiency of the small antenna at that 
frequency (less than 1/10 wavelength vertical).  I am using a 
modified NDB 100w transmitter which drives with 0.1mw in place of the xtal LO.

But do not expect that SSB or wide-band digital modes will be 
permitted once a ham band is established at 472-479 KHz (630m 
band).  Only narrow band modes like CW will be permitted in such a 
narrow band (7-KHz wide).  1-Hz frequency accuracy/stability will 
also be required (easily done with the K3EXREF).

My antenna is a 43-foot high by 122-foot long inverted-L with HB 
loading coil at ground end.  Receiving station had KAY loop 
antennas.  My noise floor is S3 to S5 at 600m using the Invert-L.

Now the pertinence to Elecraft:  The K3s and K3 with new synth board 
can operate at these frequencies (also requires the new general 
coverage filter).  Output is 1mw but this is quite capable for 
driving amps with addition of a couple buffer stages.  In general 
100w => ERP 5w and 20w => ERP 1w with short verticals.

During the winter longer paths have worked (K6 to VK).  Summer 
conditions at temperate latitudes are subject to a lot of lightning 
noise.  Similar to 160m except more reliable for short range.

I use 60m occasionally and I don't think it is "reliable" 24/7.
especially for only a 100km radius.   60 tends to go long in the
evenings.  It works well as one tool in a toolbox with several tools.
But I think it shines for longer distances than 100km.   As others have
said, it's better than 80 during the daytime and better than 40 in the
evenings for short distance.  But don't be surprised if 400 miles (600
km) is the closest you can work some evenings.

I would also suggest higher power to help with poor propagation and/or
summer QRN.

Thanks for that workaround Steve, I must give it a try here. 

I can't understand why Elecraft don't give us the option of manual notch on SSB on the KX3, as I find the auto notch doesn't always lock onto weak but annoying heterodynes but could be easily notched out manually.

For the record, ALL zip cord, including the red/black stuff and the 
glorified zip cord sold as super exotic speaker wire, is TERRIBLE for 
RFI. Twisted pair is FAR superior, and should always be used in any 
situation where there is RFI. This has been well known for at least a 
century -- in the early days of telephony when the only noise source was 
50/60 Hz power and telephone wiring often ran on the same poles as power 
wiring, the only crosstalk prevention was a crossover of the telephone 
pair at every other pole.

Max possible turns is about right for 160M on #31, 8 turns is about 
right for 40-30-20. This is for a 2.4-in o.d. toroid.

All our group buys have been #31.

Right. A choke without enough wound turns is a waste of time and money. 
BUT inductance is proportional to the length of the cable path through 
the ferrite, and the clamp-ons are much longer than the toroid, so fewer 
turns are "right" with clamp-ons as compared to toroids. Roughly half 
the number of turns is a good rule of thumb. 5 turns is a  good starting 
point for a #31 clamp that's about 1-inch long for 40M - 10M.  2 turns 
is about right for 6M, with several of these 2-turn cores in series 
along the coax.

I'm currently working on a step-by-step tutorial on chasing noise, and 
with some detail about different noise sources. First publication will 
be in the next issue of NCJ.

Subject: [Elecraft] Tnx RFI filter recommendation
Message-ID: <56D9C4C9.1090309@comcast.net>

Somebody recommended a line filter Schaffner FN2010-20-07 for a noisy 
appliance.  Thank you.

We moved to a new QTH with relatively new appliances.  Fortunately the, 
HVAC, dryer and washing machine are RF quiet despite variable speed DC 
motors.

The high end Kitchenaid dishwasher was another story. (High price = high 
RFI ?) It generated noise 30 db above ambient.  Looking at the 
schematic, it's clear why.  Lots of triacs and motors with speed 
controllers.  No line filtering except for one ferrite bead (one turn) 
wound around the hot side of the AC line.

We first tried ferrites on most leads.  This helped about 10 db.  Not 
enough.

Then we went to the Schaffner filter with the ferrites.  It dropped the 
noise to 1-2 db above ambient and occasional spikes a few dB higher. 
Nice.  Now to go back and try and recover some of the ferrites.

I don't know what the incremental cost of such a filter/filter design 
would be.  For a $1K+ diswasher, it should have been included.

Message-ID: <47EC5622-0D1C-4E3A-8D7B-DDE066511EEB@sy-edm.com>

Fellow Hams,
	I have found time to update the P3 Controls - it is now fully GUI - and you can have any type of split (not negative !!) with a p3 bandwidth of up to 10Khz, with the carrier at any offset you want from (0-5khz)

	The code is in my github page at https://github.com/timseed/Elecraft-K3-Pan-Pile-Up-Settings <https://github.com/timseed/Elecraft-K3-Pan-Pile-Up-Settings>

	It now however requires QT5 (which can be troublesome on certain days of the week to install) - but once installed - a few more packages (numpy, pyserial, guidata) and you are done.

	If anyone requires any assistance with this - please PM me off-list.	

	Regards

		Tim	- A45WG

Subject: [Elecraft] OT: W8FGU Enclosure & Shipping Changes
Message-ID: <em5bf30faf-31d1-4c99-8afe-21fd7350abf8@dvw-t100>

As I posted last week, the price increases for my enclosure line will go 
into effect tomorrow, March 5th. I've resisted the increase for as long 
as I could and have not raised my prices in over 3 years. But alas, I 
cannot ignore my supplier price increases any longer.

I've also implemented weight and zone based shipping now. As well as an 
option for Standard Domestic (First Class Package Service) for single 
enclosure orders (16 oz or less) for a $5.65 flat fee for any domestic 
USPS zone.

For international customers, I've created (painstakingly) PayPal tables 
for both USPS Priority Mail International and First Class International 
pricing, for any country that the USPS provides shipping services.

All customers should now see two shipping options when checking out of 
the shopping cart. If you use the shipping estimator in the cart, it 
will most likely give you the cheapest price, but you will still have 
the option to select your preference before concluding your purchase (I 
don't have any control over this).

Please see my site for more details: http://w8fgu.com

Thanks again for the bandwidth and if you have any questions or concerns 
please contact me at dave at w8fgu dot com.

73,
Dave W8FGU

How do I get the Big Knob off the radio so I can put the ring on?

Hi Fred,
No need to remove the knob.?
Just remove the existing rubber ring (use a small toothpick or something that won't scratch the knob)to make space between the knob and rubber until you can grip the rubber) and replace it with the new one. ?That's how I did it.
Good luck,

No set screw Fred. It sits up against a shoulder at the rear of the 
metal knob. Just loosen it up from that shoulder and it will slip right 
off.

And if you ever do need to remove the knob, the set screw hole is under the
ring (or as some say 'tyre')

No set screw Fred. It sits up against a shoulder at the rear of the metal
knob. Just loosen it up from that shoulder and it will slip right off.

I have yet to get mine on ... no time and a technical difficulty in my 
mind ... however it's only 16 bucks.  I can spend more than that [and 
often do] with jock granddaughter [softball, volleyball] and boyfriend 
[football, basketball] at Ernie's All-American Hamburgers.

Even though I don't have it on the knob yet, I can tell that it is a LOT 
less slippery than the original under my fingers, and a bit thicker.  It 
also has a slightly raised section of larger "blocks" next to the radio. 
  I can only simulate how it will be when I get it onto the knob, but 
right now, it looks really good for me.

Message-ID: <56DAE280.9060902@comcast.net>

Guys,

I wonder if anybody else noticed this.  I'm wondering if there is an 
explanation.

Picked up a high S/N K3 which has new syntheizers installed.  It also 
has the TCXO installed.  No ref lock board.

Looked at the pitch vs time from a Rb locked signal generator at 10 MHz.

I see sawtooth variations in pitch of about 0.15 Hz peak-to-peak with 
periods of about 30-45 seconds.

Anybody else notice this?

These variations do not show up when the identical experiment is 
performed using a TS-480 with high stability oscillator.  Rather all 
variations are smooth.  They did not show up on an older K3 with the old 
synthesizer boards.

Yes the variations are small but the discontinuous nature is of some 
concern.

Hi Brian,

I believe I am seeing the same thinghere... ?I used to use a program
called Dopplergram. ?Dopplergram graphs audio vs time, and is used to
look for very, very, small changes in frequency. ?By small, I mean on
the order you are describing... ?A few tenths of hz. ?

In the past, I used it to watch Ionospheric movement changes, via
Doppler changes. ?

Using the old and the new synth, (actually using the K3 at all), makes
this now seems impossible, and I have given up on it. ?

I have mentioned it here a few times, and there seems to be no
resolution. ?I asked if the external reference wold correct this, and
the consensus was-- no it would not. ?Sorry to say, this appears to be
one case where the K3 seems to totally fail at the task. ?

The sawtooth steps as the K3 corrects for drift, (or whatever it is
doing), destroy the look of my ionospheric Doppler graphs. ?

I will probably just get a different rig, and use it for Dopplergrams,
while keeping the K3 for normal use.

If you ever do figure out a fix for this, PLEASE let me know.

Subject: [Elecraft] ERR KEY
Message-ID: <004401d176e8$eebbf280$cc33d780$@Comcast.net>

When using the K3 on SSB with a condenser mike I am occasionally getting an
ERR KEY error and the vox does not trigger.  The manual talks about
attempting to key the PTT but I do not use it on SSB.  The K3 is connected
to a micro Keyer II and it does trigger PTT on CW.  I do not use any voice
connection between the K3 and my computer or other equipment.

 

Nothing has changed with my station or setup in a long time and this is a
new problem that has appeared in ARRL SSB.

The assumption would be that because it did not behave like your TS 480, it
was defective, the TS 480 being a superior benchmark? :>)

This was reported very early on with the new synthesizers and seems to have
no effect other than an emotional response in the observer. It is involved
with collection of design issues and solutions stirred up by the decision
to support very high speed QRQ QSK and the needed exceptionally short
RX/TX/TX transition times.

It also is a better method of regulation as the settling point is not off
to one side due to being "pulled" by some moving condition in the circuit
specifics until the detection threshold is reached. It is always being
tested for higher than and lower than. There is no detection threshold
bias.

Those who are into precise measurements can measure either side of this
very faint sawtooth and average them, knowing that both the high side and
low side limits have been tested by the +/- 0.07 Hz swing and the sweet
number is in the middle, without any state detection bias.

This behavior has been discussed quite a few times on the reflector ? you night do a search on the archives.   The frequency correction scheme contributes to the excellent phase noise performance of the radio.

ERR KEY should only appear at turn on if one of the key lines is
closed.  The only other report of ERR KEY has been when certain
software combinations poll the K3 too rapidly during transmit and
overflows the processor buffer.

Are you using N1MM Logger+ *and* NaP3 with their default polling
settings at the same time?

Pete,

ERR KEY indicates that the K3 is detecting a key or paddle or PTT 
closure when it powers up.
If you have the PTT-KEY menu set to anything other than OFF-OFF, your 
computer may be causing that problem when it boots because the computer 
'exercises' the RS-232 signals at boot time.

To test whether it is a jack in the K3 or an external device that is 
causing the problem:
Remove all cables except power and a dummy load.
Then power cycle the K3 several times (enough to define your 
"occasionally").
If no problem found, connect your devices one at a time and repeat the 
power cycling until you discover which one is causing the problem.

73,
Don W3FPR

When I get time I'll have to look at this.  I have an old K3 with the original 
synthesizer and no TCXO and a new K3S with a TCXO.

I also now have a GPSDO.  After getting this, I checked the K3S and was not 
thrilled to see that the TCXO required a 20 Hz adjustment.

Ed,

Remove all coax and other cables except power from the K3, then connect 
a dummy load.
If the HI SIG message is still present, it is likely there is an 
internal K3 problem.
If the message goes away, start connecting things one at a time to 
determine which is causing the problem.

Don W3FPR

Well I disconnecter all the cables except the power cable and still no go.

don't know if the problem is on the DSP board,  if it is I sure would like
to upgrade with the new DSP board which won't be available for sale for
upgrade's     could Eric can swing some weight..???

Technically, whether the 20 Hz correction is within spec depends upon
the frequency where the measurement was taken...

At 20 MHz, the 20 Hz correction is AT the spec limit.

Above 20 MHz, the correction would be WITHIN the spec.

Anything BELOW 20 MHz, a 20 Hz correction is OUTSIDE the spec.

Have an awesome day!  Back to building...

I think the spec is relative to the TCXO frequency, which is nominally 49.380 MHz, NOT the dial frequency.  I'd happy to be corrected ...

So 20 Hz against the TCXO nominal is quite within spec.

Not to open a can-o-worms again, but just closing the loop here. A while
back, I asked for help IDing the pins used on the pigtails soldered to
the ANT1 & ANT 2 panel connectors.

Well, I finally got my hands on some new ones, AND I have ID'd the EXACT
part number should I ever need it again.  I took a break from building
my delta loop's third support tilt-base for about an hour today and
finally built up the new N-connector panel mounts with pigtails.
Now, I can put the OEM Elecraft parts away UN-molested and have them
readily available should I ever need them.

Here's a link to a pic with my newly constructed assemblies in the front
and the OEM assemblies in the back:

*http://montac.com/images/antenna/UHF_2_N.jpg* (2.15 MB file)*
*
_Notes on construction:_
N-Connector, panel mount - Pasternack Part# PE45085
Wire: 18 AWG, Mil-Spec, AG-Plated, Stranded Cu, BLACK, Teflon Jacket
Pin:  MILL-MAX 3231 PCB pin
Solder: Pb/Sn/Ag/Cu (4% silver)

Soldered using high temp, broad tip for fast heat, minimum dwell.
After fully cooling, cleaned well with 99.9% Iso. Alcohol, dried.
Resistance check done and measures below instruments resolution at zero.
Exposed areas of wire/solder covered with 2-coats of conformal coating
to prevent oxidation.

Connectors installed and radio re-assembled.  (Note: PA must be removed
and shield unfastened and moved a bit to remove KAT3A board to allow OE
connector removal.  Installation is reverse of removal.)  Silver plated
wire is stiffer than the OE wire and requires some gentle shaping to
line the pins up with the receptacles on the KAT3A board.

That's it...  Back to finishing up my over-engineered tilt-base and
telescoping, free-standing (mostly) 40' mast.  I'll post some pics of
that later if anyone is interested.

Have a good evening!

Hello,
     I am trying to understand the operation of the KAT500 utility.  Not
sure if my problem is pilot error or maybe a problem within the tuner
itself.  I have the latest firmware installed.
     I am unable to manually select the antenna using the utility. I cannot
physically check the tuner as it is in a remote location. Each time I select
an antenna other than ANT1 using the radio buttons, the selection reverts
back to ANT1. This happens whether in Bypass, Manual, or Auto modes.  I have
verified the antenna setup per band. In my case I want to use ANT2 for 80
meters, and have set this up in the antenna tab. I have even disabled ANT1
for 80 meters, but the utility still won't let me select ANT2 for 80 meters.
The KAT500 also does not automatically switch when RF is applied, even
though the utility will read the correct 3.5 MHz frequency.
     Any ides for what to check?

I think you have to have the KAT3 tuner physically installed in the 
radio to be able to select ANT 2 on the radio or in the utility.

Hello,

I'm trying to interface a KX3/KXPA with a kRC2 band decorder. Basically, I built a cable to connect the AuxBus pin on the KRC2 XCVR port t the GPIO input on the KX3-KXPA adapter cable, which is driven by KX3 ACC2 port. This doesn't seem to be working and I'm not sure the right setting is enabled for the ACC2 port to allow for AuxBus communications. Has anyone tried this? Any help is appreciated....

Good Afternoon,
     I am sorry this is so late but I have been without power since dusk 
yesterday.  The heavy storms pummeling the West Coast are bring with 
them plenty of high winds.

I will be unable to run either net for a few weeks while I replace my 
antennas and repair my K3.  If anyone else is able and willing to run 
the net please do so since I know the stalwarts are always ready for 
Sunday's activities.

I will try to listen along with the net if I can.

Robert,

The KX3 ACC2 I/O menu parameter should be set to TRN CTRL.

The output of the KX3 ACC2 IO is 3 volt logic while to KRC2 uses 5 volt 
logic.  It may be that the AUXBUS signal from the KX3 is not properly 
switching the input of the KRC2.  You may have to add a 3V to 5V 
translation circuit.
Note that I have not tried the KRC2 with the KX3.

This is not a good idea - the two are not compatible. The KX3 does not speak the auxbus protocol the KRC2 needs, plus the voltage levels are not compatible.
The best way to use the KRC2 with the KX3 is to use serial port communications. Realize the KRC2?s highest data rate is 19200 bps. Also remember that the KRC2 does not implement the full EI-232 interface, so be sure to fabricate a cable that only connects pins 2, 3 and 5 to the radio (or computer).

Hi Kevin,

Tom,

For many years, I used a Creative Labs E-MU 0204. The last time drivers were written for that interface was late 2014 and it is no longer in production. When I upgraded to OS X 10.11, I could not use the interface because of some changes in OS X. I purchased a Focusrite 2i2 and cannot be happier (unless I had purchased the Focusrite 6i6 for more I/O). I regularly decode JT65 and JT9 in the mid -20s. I have had at least one JT9 decode at -27 using the Focusrite.

The 2i2 is available from most online big-box places for right around $150. All you will need to purchase the appropriate cables. With both the K3 (I know you said K2) and KX3, I use a 3.5 mm TRS to 1/4? T and R mono from radio out and a 3.5 mm to 1/4? mono to radio input. The Focusrite USB interfaces are red anodized aluminum and you can adjust both input from the radio and output to the radio with dials on the front. It also has a separate headphone stereo monitor that can be turned on and off with volume adjustment. The adjustments right on the front of the Focusrite make operation very easy.

Joel - W4JBB

Tom,
Tom,

If you want to use the soundcard for panadapter applications, then go 
with the recommendations on the LP-Pan site, but there are several users 
that have been reporting that the ASUS U7 reverts to 48k and there does 
not seem to be a solution.  The ASUS U5 does not seem to share that 
problem.  In addition to the bandwidth of the card, the noise floor and 
the lack of a zero frequency spur are important considerations.
Look at the LP-Pan Yahoo Group for a lot of comments.

If your soundcard will be used for digital modes only, then you do not 
need a 'top of the line' soundcard, most any will do.
But the LP-Pan website can still be an assist in selecting one - look at 
the noise level on the various cards to find the better ones for 
soundcard digital mode use.  The internal soundcard in your computer may 
prove to be adequate, but turn off the sounds generated by your OS if 
you use the internal card so you do not transmit those sounds.

That's strange. Never heard a single issue with the Asus u7 stuck at 48 and i know of many many people using them. The only reason that happens is that people often set the card as the default sound card which should not be done.The u7 in my experience, is the quietest and least likely to have Spurs.Cards to stay away from now a days with win10 are the emu cards. Upgrades to win10 may work but not fresh installs. Drivers are at least 4 years old and still beta.Tomva2fsq.com

I used a SignaLink for quite a few years and then I changed to a 
Tascam US-122 mkII. When I used the SignaLink on PSK, I had to 
ride the RF gain to keep the digitized audio volume within 
acceptable input levels. With the Tascam, I no longer need to do 
that. The downside of the Tascam is it requires special drivers 
which aren't available for ARM linux.

You can get by with a minimal sound card, but there is value in 
a better one.

The reviews on Amazon and NewEgg need to be taken with a grain of salt.
The vast majority of those reviews are from people who aren't 
technically inclined and you get a lot of "it sounds great" reviews. If 
you're using this for the LP-Pan take the advice of N8LP. He knows what 
works with his hardware. You might think about joining the Yahoo group 
as well.

If this is for a Windows 10 computer you may be stuck in driver "no mans 
land" until ASUS releases drivers. Welcome to the wonderful world 
Windows OS "upgrades".

What are the negatives?  Do they relate to the way you want to use a 
sound card? What do you want a sound card to do? Digital modes? Any 
competent sound card will work for that. Spectrum display? I'd go with 
N8LP's assessment on that.

Did you not read the post?  He's talking about a KAT500, not a KAT3.

Tom,

If the problem is only happening when the Asus U7 is the default 
soundcard, then how do you deal with the tendency of the Windows 
operating system to set any newly installed soundcard as the default?  
Seems like a "catch 22" to me.
Yes, the specs on the Asus U7 are very good, but for panadapter use, it 
needs the 192 kHz bandwidth.

Wondering if anyone used the above in the contest with N1MM+ and 
experienced delays after the macro .wav played out? They were long 
enough to where I only heard the very end of my call when a station came 
back to me. I used Audacity to cut the tails off. prior to this.

Also wondered if there was a way to record a wav file directly in MM+ as 
sitting I could sitting in front the K3? The Cntrl Shift F-key routine 
didn't work.

As a side note, also not able to record to the M1-M4 message keys on the 
K3s/0 in cw either as on the K3.

You're absolutely right, Wes. It's obvious my problem was pilot error.

I use a U7 with the KX3 and HDSDR. There is an issue with the
initialization of the 24 bit drivers. I have set up for 24 bits, 192 kHz
and line in using the Asus software, and 24 bits and 192 kHz in Windows
control panel. When I turn the computer on and use HDSDR for the first time
I have to do the following:

Start up HDSDR and select Start.
In HDSDR switch to 16 bit drivers.
In HDSDR switch back to 24 bit drivers.
In HDSDR select bandwidth and switch the output bandwidth to 192 kHz and
back to 12 kHz for the small waterfall. The input remains 192 kHz.
In HDSDR close the bandwidth box.
In HDSDR hit Stop and then Start

After all that it works until the computer is shut down or the computer
sleeps.

If the computer sleeps, in HDSDR hit Stop and then Start if the spectrum is
backwards (moves the wrong way when you tune) or is mirrored around the
center.

Other than the annoyance above, it works well. I just live with the "dance"
at startup.

Hope this helps

Sometime ago I installed the K3EXREF which I feed from an external 10MHz double oven Xtal oscillator. I am confident the K3EXREF is installed and configured correctly as when in use and the external oscillator is connected the front panel says REF*CAL with the * blinking. Attempting to change the local oscillator frequency gives the message "Locked" just as the manual says.
However, I am puzzled as the local oscillator frequency display slowly drifts down from 49.379.675Hz to 49.379.622Hz over a period of at least an hour from K3 switch on.  I leave the external oscillator on permanently. I was expecting the local oscillator to rapidly get to its final frequency. Can someone explain whats happening as I am puzzled??
My firmware is the latest version.

Andy - Without the K3EXREF connected, the REF CAL frequency will be
fixed and the K3 will drift, albeit very slightly, particularly when it
is first switched on.  With K3EXREF locked with your 10MHz standard the
REF CAL frequency will vary to correct any drift in the K3. If you
measure the output frequency of your K3 with an accurate frequency
meter, such as a digital counter locked to a standard, you will find
that your K3 is stable to within +/- a couple of Hertz.

All:

 

Even after considering the P3 manual (page 21) and with AGC off, I find the
following difference in S unit measurement odd.

 

 

Band  P3    K3

75m   S5    S9

10m   S0    S2

 

 

I'm trying to ascertain an accurate noise level reading at my QTH.  Does
anyone have any thoughts on the degree of difference in these readings?

Content-Type: text/plain;	charset="us-ascii"

Hello,
     I am trying to understand the operation of the KAT500 utility.  Not
sure if my problem is pilot error or maybe a problem within the tuner
itself.  I have the latest firmware installed.
     I am unable to manually select the antenna using the utility. I cannot
physically check the tuner as it is in a remote location. Each time I select
an antenna other than ANT1 using the radio buttons, the selection reverts
back to ANT1. This happens whether in Bypass, Manual, or Auto modes.  I have
verified the antenna setup per band. In my case I want to use ANT2 for 80
meters, and have set this up in the antenna tab. I have even disabled ANT1
for 80 meters, but the utility still won't let me select ANT2 for 80 meters.
The KAT500 also does not automatically switch when RF is applied, even
though the utility will read the correct 3.5 MHz frequency.
     Any ides for what to check?

I use an Asus XONAR U7 with NAP3 and CW Skimmer on a Lenovo Windows 10.x machine , attached to the K3 IF via LP-PAN2.  Almost all USB sound cards are quirky to set-up with your particular computer and your particular audio applications.   As for the "stuck" 48k sample rate:  make sure the little switch under the XONAR U7 is in the USB Audio 2.0 position, then follow the guidance for loading the correct driver - do not let Windows load the default driver.

I hope this helps.

If the problem is only happening when the Asus U7 is the default soundcard, then how do you deal with the tendency of the Windows operating system to set any newly installed soundcard as the default?  
Seems like a "catch 22" to me.
Yes, the specs on the Asus U7 are very good, but for panadapter use, it needs the 192 kHz bandwidth.

Elecrafters,
this has been discussed a long time ago, is there any news about this:

When in TEST MODE the TX led is flashing to inform you the tx can not be 
engaged.

When TX INHIBIT is ON . the TX led is flashing all the time, even when 
TX is not inhibited. Is it only me or are others puzzled too?

I -think- the way it works is that when the K3EXREF is locked with the external frequency standard on 10 MHz, this is used to measure the frequency of the TCXO. The value of that frequency measurement is then put into the K3 REFCAL setting. If the TCXO drifts slightly as they all will, then the frequency difference is detected and the value in REFCAL is changed to match, hence keeping the frequency of the K3 correct, without actually phase locking the TCXO to an external reference which could degrade the low phase noise performance of the K3's synth.

Basically the K3EXREF is doing the same thing automatically as you would manually when doing the calibration, by measuring the TCXO frequency and storing that value in REFCAL. The K3EXREF acting a frequency counter with a high stability external 10 MHz reference.

Hope I have that right.

So, it would be normal for the value in REFCAL to change as things warm up even with the external reference into the K3EXREF, because the TCXO is not locked, just measured.

To All,
I sent a support request to Elecraft regarding my issue and they replied
with the following:


======== Start E-Mail Here ===========
Hi Jim,

>From what you indicated, your Bias is turned ON for the MH2. If you are
using headsets which require Bias, this is important.

You can either use VOX or connect a footswitch to the back of the Mini
(PTT) to place the Mini in transmit. The XMIT/tune button can not be used
for PTT.

The microphone should have a mono 3.5 mm plug. That would go into the MIC
jack on the side of the Mini.

Let me know if this helps.

I wired up a PTT using the K3/0-Mini "PTT" jack on the rear; plugged my
headset/mic into the left MIC/SPKR jacks and it WORKED...

Apparently, you MUST use the hardline PTT for the K3/0-Mini to accept MIC
input from the left side jacks.  Pressing the XMIT button and using CAT
control did NOT enable the headset mic to work...

The question remains - why would the design require a dedicated PTT for
headset use?  I thought plugging the headset into the left MIC jack
"disabled" the front panel MIC (8 pin) jack...

Anyway, I did want to share with the the group.

Do you really mean that the red TX LED is flashing? 

According to the manual, it is normal for the "TX" symbol on the LCD
display to flash continuously if TX Inhibit has been selected.

But WHY? The continuous flashing serves no particular purpose - but much
worse, it hides the important warning that Test Mode may have been
activated inadvertently (and who hasn't done that?) 

Please can Elecraft remove that feature.

Message-ID: <56DDC0E4.4070009@sonic.net>

The indicated noise level depends on the receive bandwidth.  For 
example, if you use a narrower bandwidth on the K3, you'll notice that 
the S meter reads lower.

The effective bandwidth of the P3 is approximately one pixel on the 
display, which is SPAN/468.  So, for example, if the span is 47 kHz, the 
effective bandwidth is about 100 Hz.  If the K3 bandwidth is 2.7 kHz, 
then the P3 should read 10 * log (2700/100) = 14 dB lower than the K3. 
14 dB is roughly 3 S-units.

When measuring a steady carrier, the K3 and P3 should read the same, 
since all of the signal is within the bandwidth.  The P3's amplitude can 
be calibrated with the "Lvl Cal" menu selection.

Looks to me like you need to find a buddy in the States who'll get you

USPS First Class International is $13.50... Much more reasonable... and
it has free delivery confirmation.

What exactly are you trying to fix...  Class 7 has higher twist rate,
overall shielding and shielding per pair.  It is certified for use up to
600 MHz at up to 100 meter runs.  Terminated with 8P8C connectors.  CAT
7a is augmented 7 good up to 1GHz...  And there is a draft in the works
for CAT 8 (good to 1.6-2.0 GHz)  still with 8P8C connectors.

I'm not sure what the RFI issue would be that would require CAT 7... 
Tell me what you're trying to fix and I can offer more info...

Sorry....  forgot to include... this was a hypothetical package weighing
4 ounces (box).  You could get the weight down with a bubble envelope
and the part weight next to nothing...  But a box would be more sure to
get delivered intact.

I would like to feel some tactile feedback when using the 
RIT/XIT knob to make gross changes in frequency. If there was a 
detent for each change in frequency, then I would know how much 
to turn the knob without having to look at the display.

The same feature would be nice on the other encoders -- 
Shift/width/speed/pwr and the two VFO knobs.

I don't know about the practicability of getting encoders with 
tactile feedback.

I have been told that USPS shipping rates will be reduced by 17%, 
sometime in April. Not a huge drop, but it helps.

Subject: [Elecraft] Dual Receive on a K3?
Message-ID: <1457385588942-7614998.post@n2.nabble.com>

Hey All,

I'm just getting to know my K3 (w/o sub rx) again after being inactive for a
couple of years.  Can anyone tell me if there is a way to have dual receive
with my K3?  

That is, I would like the ability to hear both the tx and the rx frequencies
at the same time.  I know that I can op split and just use the rev control,
but I'd like to hear both frequencies at the same time on CW.  It could even
be just using RIT/XIT rather than SPLIT, as long as I could be 2 or more KHz
off the rx frequency and hear both equally.  

Would my only option be to add the sub-receiver or upgrade to the KX3? 

Tnx for any replies and, 

73
W6FG

I ship a lot of USPS Priority Mail too.

Yes, USPS Priority Mail rates did increase recently, but 1st class mail 
letter postage stayed the same.
I am seeing that the rate for 1st class mail was going to be reduced - I 
have no confirmation about Priority Mail, but I expect that it stays the 
same as it is right now.

So use up all your "Forever" stamps that you paid $0.49 each when you 
bought them before the rate reduction goes into effect - they will be 
worth only $0.47 after April 10.

Not possible without the sub-RX.

The KX3 does have 'dual watch' which will allow a small difference in 
frequency.  The KRX3 can even be on different bands if you set VFO IND on.

As far as I know, the sub receiver is the only option. The KX3 
has dual watch, which does many of the same things, but has 
certain limitations. For example, the KX3 can not use narrow 
band filters with dual watch because it needs to have a wide 
enough bandwidth to tune both frequencies at the same time.

During the ARRL DX SSB contest, there were several stations that 
were listening in the US CW sub-band while transmitting in the 
SSB sub-band. KX3 dual watch is limited to 15KHz, which is not 
wide enough for this kind of operation. There were also DX 
stations doing the reverse.

73 Bill AE6JV, who finally gritted his teeth, got the 
sub-receiver, and is very happy he did.

As am I with my sub Rx. Expensive? not compared to buying a 2nd radio 
and using my old Johnson tube based TR switch. I don't often use the 
Sub Rx & when I do, its usually for Diversity. Really slick 
integration.

There are well known issues with equipment using one of the wired 
Ethernet standard rates (have forgotten which one) generating carriers 
at several frequencies in the HF bands and on 6M. I'm primarily a CW 
guy, so the ones I run into are around 14030, 21052, the low end of 10M, 
the low end of 6M, and a couple of frequencies on 30M. These signals are 
radiated as a common mode signal, and I've been told that properly 
terminated shielded CAT5/6/7 eliminates it. Properly terminated means 
both in the cable-mounted plug and the equipment-mounted jack. I've also 
experienced broadband hash on 2M with a talkie within a foot or two of 
unshielded CAT5/6, including Belden's excellent Mediatwist cable.

In addition to its use for wired Ethernet, unshielded CAT5/6/7 is quite 
useful in noise sensitive circuits because of its high twist ratio. As 
with Ethernet, twisted pairs reject noise and crosstalk ONLY when wired 
with one pair per circuit -- that is, or and or/blk as a circuit, bn and 
bn/blk as a circuit, and so on.

So use up all your "Forever" stamps that you paid $0.49 each when you bought them before the rate reduction goes into effect - they
will be worth only $0.47 after April 10.

Yes.
Also once any potential driver issue is rectified and the sound card is 
installed remember EXACTLY which USB port you plugged it into and use 
the same port always. Even though the driver is installed if you 
disconnect and reconnect to a different port Windows will see it as a 
new device and start the driver dance again.
Unless plug and pray has gotten a whole lot better (I doubt it).

Almost all USB sound cards are quirky to set-up with your particular computer and your particular audio applications.   As for the "stuck" 48k sample rate:  make sure the little switch under the XONAR U7 is in the USB Audio 2.0 position, then follow the guidance for loading the correct driver - do not let Windows load the default driver.

I believe that is the way it is.
53/1000 of a hertz over an hour?
I'd give that up all day everyday for the spectacular lack of phase 
noise in the K3s or K3 with the new synth.
It's not a cesium clock.

If the TCXO drifts slightly as they all will, then the frequency difference is detected and the value in REFCAL is changed to match, hence keeping the frequency of the K3 correct, without actually phase locking the TCXO to an external reference which could degrade the low phase noise performance of the K3's synth.

You must be in ?course? tuning mode.  Look at the instructions for ?tuning rates? on page 11 of the manual.

I didn't really mean tactile "feedback," my fingers just stick to the 
knob better.  "Small motor" capability declines with age, my CW RX speed 
has stayed constant over the years. but my sending ability has declined. 
  I just have less difficulty setting a specific frequency than with the 
original ring.

something is acting up on my end... my last response came through "blank".

Here's another try:
*************************************************************************
There is no unshielded CAT 7/7a...  at lower classes the
cable/connectors may be chosen as UTP or STP...  Cat 7 and above is
DOUBLE shielded.  Overall shield (braid) and shield per pair (aluminum
tape).

Any device putting out RFI as common mode are NOT in spec....  Whether
they can be "fixed" or not has a lot to do with what "mistake" in design
caused the problem in the first place.  That has to be determined by
device.  Depending on the cause of the RF generation, there are a number
of ways to mitigate/eliminate the problem...  Shielded cable is only ONE
possible component in the overall solution.

A non-inclusive list of causes:

Badly designed and/or shielded switch mode power supply (wall wart OR
internal).  A wall wart can radiate via the DC cord to the device and/or
send the signal into the device via the DC cable and then radiate via
the chassis or signal cables..  USUALLY internal PSs are adequately
shielded... but poor input filters or none at all can let the bad stuff
through.

Wireless radios that are improperly designed or shielded can also be the
culprit.

Not having a separate logical and chassis ground can be a problem...

Crappy fans...  (best devices have properly designed passive cooling).

Lots of ways for a bad design to create noise.

Shielded cables work best in my experience when you can create an
isolated chassis (or supplemental Faraday cage type superior to the
chassis (or internal to a plastic case) where the outer shield of the
cable and connector housing can be connected in one continuous shield
around the device(s) and the cable, etc, etc...

The benefit to CAT 7/7a would be the double shielding and the superior
connector termination and housings... make for easier continuous shield
external connections to drain/ground, et al.

Typically, it would be cheaper/more reliable to buy a properly designed
device in the first place...

Note: there is a CAT 8 draft spec out now...

CAT 7(+) would make an excellent 4 circuit control wire for remotes and
the like since it has shield per pair...
CAT 7(a) cable, connectors, and tooling is insanely expensive by
comparison to 5/5e and even 6(+)

Perhaps, but such devices are VERY common in the consumer world. I have

Yep. Suitable common mode chokes can make a big dent in the RF trash 
radiated by the cable.

The Ethernet birdies/carriers I listed are from the data stream, NOT 
from the PSU. Of course the PSU often generates trash, but it's 
DIFFERENT trash. :)

Trash that radiates to our antennas is COMMON mode, not differential 
mode, and common mode is caused by improper return paths, and it cannot 
be "filtered." Filtering affects differential mode trash.

I can't see any way that a 900 MHz or 1.8 GHz radio can cause RFI at HF. 
It is the baseband digital signals that have HF components.

> Not having a separate logical and chassis ground can be a problem...

WRONG -- that is a CAUSE of problems, not a solution. See Henry Ott's 
classic text on EMC.

EXACTLY WRONG. For shielding to be effective, it must be continuous, 
including a termination to the shielding enclosure at both ends. Again, 
see Ott.

Of course. :) IF you can identify one. But that requires a published, 
competent, technical review of products on the market that include RFI.  
Call me collect when you find such a thing. :)

Those working in the world of pro audio deal every day with microphone 
signals in the range of -140 dBu, with required dynamic range of at 
least 110 dB, and typically have 24-32 mics active in a given recording 
or production. Any coherent noise that is present in multiple inputs 
will degrade s/n by 3 dB per doubling of the number of inputs, and 
modulation of an RF signal present on multiple inputs will be coherent 
after detection. My point is that pro audio faces a s/n problem FAR 
worse that we do in the radio or computer networking world. In that 
world, we have learned that TWISTING is at least as important as 
shielding, and often MORE important.

That said, serious contesters with extensive IT background have reported 
that STP does kill Ethernet birdies, and I believe them. I've never 
heard a suggestion that CAT7 was needed, nor have I ever read a spec for 
any of these cables.

Yep... just like a LOT of consumer grade electronics, the manufacturers
intentionally ignore or falsify the FCC certifications.  Generally, you
get what you pay for.

That's a very definitive statement...  while an unlikely cause of
multiple HF region emissions, switch-mode PS frequently switch at
frequencies in/around HF frequencies.

A wireless "router" radio is a radio just like any other...  they take
an input signal, massage it and send out a signal...  they are subject
to the SAME design issues as any other radio.  IF frequency(ies),
mixers, oscillators, et al.  Subject to the same mixing products and

Perhaps I should have been more precise...  logical ground and a chassis
shield.  Although, there ARE in fact many electronic devices where the
device itself has an isolated logical "ground" and the entire device is
located WITHIN a totally separate shield from end to end essentially
floating the devices on each end and the signals inside their own "space".

Read what I wrote again.  Chassis/shield to cable connector shield to
cable shield to connector shield on the other end to the
chassis/shield.  One continuous shield...
What may have confused you is that I was considering both well-designed
devices with chassis designs that act as or contribute to the shielding
vs. the majority of consumer grade devices which do NOT have a shielding
chassis...  e.g. plastic case with venting, etc.  MOST of this consumer
grade stuff has 8P8C modular jacks that are designed to accept UTP RJ-45
connectors made of plastic thus they do not provide any means for a
metal shielded connector (a la STP CAT 5/5e/6+ or all CAT 7 and above. 
IF you didn't do anything else, the STP cable and connectors would do
little to assist because they are NOT connected to the
chassis/supplemental shield and have no path to ground.

On a device with a plastic case providing no overall shielding and/or if
the radio shield or PS shield, or any other potential "trash" maker
(common OR differential) circuit is not properly designed and/or
shielded, and/or filtered, or other mitigating method, you're peeing
into the wind by simply adding shielded cables.  You can connect a drain
to ground from the cable/connector housing and that will help...  BUT
what you really have to do to clean up a non-FCC compliant device
putting out harmful/unwanted IF is to either/both/hybrid:

1) Construct an internal shield that will block the radiation from
leaving the enclosure AND connects to the signal cable shields and
thence to ground...  OR, if you can't do it internally,...
2) create and EXTERNAL shield with the same electrical characteristics.
3) Some hybridization of the 1 and 2.

Bottom line...  we said the exact same thing...

On that we agree...  Back in the days of IDE hard disk drives, the
standard was 12-24 inches MAX cable length because of the flat ribbon
cable (and other considerations).  I successfully designed shielded
twisted-pair cables terminated to the 40-conductor internal connectors. 
We got multiple increases in the spec length with no performance
degradation out to many feet and external HDD enclosures (used for
thermal design and other in chassis considerations).  Ultimately, after
tweaking wire size, twist rate, and adding overall shielding (properly
terminated), we were able to remotely locate ALL of the HDD for a 12
board/ 1 master encryption cluster more than 100 feet away with perfect
performance and no RF, cross-talk, or timing issues.  Same thing with
Ethernet cables and others.  You can frequently multiply the spec length
or signal frequency/data capacity using many of the same methods.

Signals are signals... whether they are in audio interconnects, mic
cables, computers, et al.  You do what is required to keep signal
integrity and not cause external interference.

IF they have an "extensive IT background" they'd know a floating STP
cable won't work nearly as good as one where the shield is properly
terminated/utilized.

Hello,

Are there any compatibility issues using a K3 to control a K3S with

Message-ID: <201603080538.u285cVhG008424@mail42c28.carrierzone.com>

The K3EXREF circuit is essentially a AFC (sort of) where a highly 
accurate 10-MHz reference is used to measure the frequency of the 
TCXO and send a frequency correction "word" to control the TCXO so 
that the error from 49.380 MHz is removed.

As I understand it this comparison is done about every 
4-seconds.  The TCXO drifts with temperature so it will definitely 
change when you first power on the K3.  This drift will slow at some 
point and hover around a offset level (mine is about 49.380.080.  The 
TCXO is actually tuned to correct from that so REF*CAL is only 
showing the amount of offset that is being corrected.  Output of the 
TCXO is not 80-Hz high.  It would be if the EXREF did not correct it.

I have the K3/10 so only have the 12w PA which does not add as much 
heat in transmit as the 100w PA.  So that lessens the amount of 
temperature drift of the TCXO.  The TCXO-3 is better than the std 
TCXO so the improvement the EXREF makes is better with it.  On 
transmit on 28-MHz using the EXREF, I see approx. +/- 2 Hz frequency 
error with the TCXO-3.  This is equivalent to 0.1 ppm.  Without the 
EXREF my error is five time larger or about +/- 14 Hz.

There is still a slight amount of frequency drift since the TCXO is 
operating normally in between the times the 10-MHz reference checks 
and corrects frequency error.  This explains why a small amount of 
drift still occurs vs what happens with a phase-locked 
oscillator.  The result is that the frequency will appear to look 
like a ramp waveform over the 4-second interval between corrections.

The reason for choosing this form of frequency control is it 
preserves the excellent low phase noise of the K3.  PLL are difficult 
to make with as low phase noise.

If any of this is incorrect, perhaps one of the Elecraft engineers 
will correct what I wrote.

Actually, switch-mode power supplies run in the range of 10-50 kHz, NOT 
at HF.  It is the unfiltered high order harmonics that we hear at HF.

But the IF and mixing products are NOT at HF. Trash from WiFi systems is 
produced by the baseband digital electronics and the switch mode power 
supplies, NOT from any part of the RF system.

I don't get "drain to ground."

It IS possible to make unshielded equipment RF-quiet with proper circuit 
layout and construction. The return for current in a circuit trace over 
a continuous "ground" layer flows in the very small area of the "ground" 
trace directly under the circuit trace, forming a transmission line. In 
effect, the "ground" layer shields the conductor. Thia single "ground" 
layer technique is called "microstrip; a second "ground" layer on the 
other side of the trace provides much more shielding, and that 
construction is called stripline.

With this sort of construction and no chassis, shield return would need 
to be to an island of copper at the perimeter of the board, and all 
cable shields and external "ground" paths (like power supply) would need 
to be terminated to that perimeter shield. As with a chassis, shield 
current stays "outside the box." But if that "ground" layer is broken 
under the signal trace, return current follows whatever path left to it 
by the whim of the PC board layout "artist," which often forms a large 
loop that includes the chassis or some long return path on the board. 
Now, it's no longer a transmission line, it's an antenna (and a magnetic 
loop), so signal escapes both by antenna action and magnetic coupling.

Not quite. What I've observed is that MOST of the noise we hear on HF is 
common mode current on cables connected to the device, NOT due to the 
device being poorly shielded. Yes, SOME noise is radiated directly from 
poorly shielded and/or equipment with the PCB layout issues I noted, but 
that part of the noise is rarely dominant because the antennas inside 
the box are too small to be efficient at HF, whereas the antennas 
carrying the common mode current (the interconnecting cables are usually 
much longer (including path to other equipment, power supply, facilities 
ground, etc.)

I would NEVER waste my time shielding a poorly shielded box that was bad 
enough for me to hear. I would dump it and buy something without that 
problem.

While I seem to be able to adapt to many things that bug others, and I
had adapted to the original knob/ring, I really do like the feel of this
one. There's a significant increase in the tactile sense on my fingers,
and I seem to be able to set a frequency to 1 Hz more easily.  It's

You could get an LP Pan panadapter (http://www.telepostinc.com/LP-PAN.html) 
and this will allow you receive on a second frequency on your computer using
the VFO B knob to tune (distance from VFO A determined by the sound card you
use - panadapter bandwidth can be up to 192KHz).  You can also listen to the
VFO A frequency applying different filtering and noise reduction techniques
to those set up on your K3.

When you go to 15Mtrs on USB from a different band the output power is very
low on the output meter on the radio, if you change to CW mode and send a

Almost.

The TCXO has no control input and is not tuned; it is only measured.

The measurement information is passed to the radio's MCU which then uses 
the data to determine the correct value to command the synthesizer(s), 
drive the REF CAL display, and so forth.

Message-ID: <56DECAFD.1050701@gmail.com>

Just an unsolicited tribute to the K3's diversity feature. I had been 
trying to work 8R1/K9XK in Guyana for a few days without success. 
Although I usually do OK with that part of the world, he's been too deep 
in the noise. I finally caught the propagation on 17 meters this 
afternoon and could actually tell that he was there. But switching on 
diversity turned the mere suspicion that I was hearing him into a 
solidly copyable signal, and I worked him!

Technical details: I am using diversity to good effect on all the bands 
that I have antennas for, 40-10m. My transmitting antenna is a rotatable 
dipole at about 35m (on a building) and the auxiliary antenna is a Pixel 
Loop
<http://www.dxengineering.com/parts/pxl-rf-pro-1b>
about 3m lower and 8m away from the center of the dipole. Although this 
is supposed to be too close for good diversity, the vertical 
polarization of the loop apparently provides the separation needed, even 
on 40m.

Bob,

Are you driving the audio level sufficiently?  Inadequate audio drive is 
a common cause of such 'power hunting'.
You can do this off the air - turn the power to zero or connect a dummy 
load.
Then turn compression to zero.
Talk normally into the microphone and adjust the MIC GAIN to produce 5 
to 7 bars on the ALC meter.
Now you can increase the compression to the desired level.  3 to 6 dB is 
often suggested, but it is your choice.

After a band change, the initial power should be low, but should quickly 
increase to the requested level after a few syllables.

Don W3FPR

the routine of the CWTs slightly. In the second week of March, June and
November, everyone taking part in the CWTs is asked to keep their CW speed
down to 20 wpm or less in order to welcome new graduates who are not yet
ready to cope with the usual higher CW speeds. Also, past and present
students and advisors are asked to send CWA in place of the usual membership
number or state/province/country code in the exchange.

Everyone is always welcome to join in. This week, though, please moderate
your CW speed in order to make it more fun and less stressful for the new CW
Academy graduates.

Time: March 9, 1300-1400Z; 1900-2000Z; and March 10, 0300-0400Z.
Frequencies: approx. 28 kHz above the bottom of the band and upwards
Exchange: Name plus CWOps membership number, "CWA", or state, province or
country code
Logs: No log submission, just report your results at 3830scores.com

Thanks, and CU in the CWTs.

73,
Rich VE3KI
CWOps CWT manager

This can be accomplished by any quality SDR with the appropriate
software (there are multiple approaches). There are several newer
SDR hardware devices that are less expensive than the LP-Pan and
sound card combination that are not tied to somewhat unstable

Yep... I was wrong, you are right.  Not fundamental, but harmonics.  I

I agree that the much more likely candidate is the Ethernet switching. 
But the standard Ethernet signaling is differential...  PoE could
definitely be a culprit, since one of the methods involves tapping the
Ethernet pulse transformer for a voltage source.  But, whatever the
SOURCE of the trash, it is generated inside the device and inadvertently
being radiated over the UTP.

Bottom Line: There is no shortage of potential places inside a typical
Wireless Switch/Router where RF issues can be created...  especially
when their designs are targeted to meet a price point rather than comply
with PART 15.  I'm a bigger fan of eliminating the source than I am of
mitigating the effects... at least these days I am.  There was a time
when I enjoyed "making stuff work".

I confess, I don't design wireless data radios, so I have no idea what
the IF/oscillator freqs are.  I was simply stating that wireless data
radio is a radio.

Don't shoot the messenger.  Tell the DoD, NASA, NSA, and a host of
private companies to include Cisco, etc.  I'm just telling you what's
out there.

Ott wrote a lot...  are there specific references you'd care to share? 
I'd be interested to read some of his theories with respect to this
subject.  Online refs if possible; I've exceeded my book budget for the
month... heck for the year.  ;-)

> I don't get "drain to ground."

I apologize... perhaps I stated it wrong.  Many shielded cable types
(not typically STP cable)  come with a "drain" wire to make it easier to
terminate the shield...  not used a lot in data cable...  but I
sometimes use the term to refer to a conductor that connects to a cable
connector housing or to the cable shield whose purpose is to assist in
grounding the cable shield or creating continuity between the cable
shield and the shielded termination.  In the case of the "plastic crap"
I described above without additional shielding added and internal
connection to the cable connector somehow, the alternative solution of
trying to make the STP cable a less efficient radiator involves using
"drain" conductors to try and shunt the RF to ground before it can radiate.

> It IS possible to make unshielded equipment RF-quiet with proper

Yes, of course.  But MOST manufacturers have "discovered" that they can
design to a price-point and ignore Part 15, et al. because of the
unlikelihood that the FCC will pursue them for their massive violations
(think of the number of non-compliant consumer data devices in the filed
and sold each year).  Sad really, because it doesn't take all that much
more time to design and manufacture a proper board.  One would think
that a couple hundred thousand HAMs making complaints against a massive
number of obviously non-compliant crap consumer electronics might
generate a response... Needs to be coordinated.

<PCB design criteria was here>  We agree on that entirely.

Gotcha...  Having never needed to chase RFI to HF in my own home/office,
I'll defer to your obviously superior level of direct experience.  I
think it might be interesting to actually have the harmful RFI tracked
to specific causes in a large range of device models to see if the
sources cluster around a particular design "flaw"/choice(s).

Absolutely...  Today, I would agree with you, but there was a time when
I would not have had the economic luxury of "dumping" a piece of
equipment.  It's nice to know that you CAN do something because you've
done it before. 

Have a good day, Jim!

Without repeating a long response to my long post, we do agree on all 
key points. Including the fact that the vast majority of manufacturers 
get shield bonding wrong.

Here's a link to Henry Ott's website. Scroll down to find a reference to 
the latest edition of his book. It is often used as a text for EE 
courses in EMC.  I attended his 3-day EMC course about ten years ago. It 
was time and money well spent. I'm past chair of the Tech Committee on 
EMC for the AES, and subsequently invited for him to present expert 
lectures to two AES Conventions.

Thanks, Brendon.  Hopefully the miniaturization offered by SMT reduces 
the size of the antennas that radiate any trash. :)  But that may be 
wishful thinking -- W6GJB encountered massive noise on HF that he 
tracked down to computer extension speakers with built-in power amps 
that were powered from a USB port. I suspect that this sort of circuit 
was used.

When Eric VA7DZ, Fred KE7X and I were all experimenting with KRC2s for 
our K3s, I also connected mine to the KX3 with the help of Jack Brindle, 
KRC2 expert.

Here's what I did to the KRC2 to make it work in between the KX3 and the 
computer:

1.  Set KX3 menu item RS232 to 19200b.  Set the appropriate software on 
the computer to 19,200 baud.

2.  Use only the following jumpers in the KRC2:  W3, W8, W9, W10, W21, 
W22, W23.

3.  Make a special jumper wire to go from the RS-232 connector side of 
W11, to the RS-232 connector side of W20.  This carries the DTR signal 
between the two RS-232 connectors without actually bringing it into the 
KRC2 circuit.  It's voltage is incompatible with the KRC2, but it needs 
to be "carried through" if you intend to break out the DTR signal to, 
say, key the KRC2 with a transistor (or perhaps use DTR for PTT, or you 
could figure out the RTS pin on the RS-232 if you prefer).

The circuit diagram in the KRC2 assembly and operating instructions 
booklet is very useful to help to understand the jumpers.  Normally, for 
a K3, you'd use W16 to enable the Auxbus in the KRC2.  W3 tells it to 
use the serial port, not the Auxbus. W8 sets it to 19,200 baud.  W9 and 
W10 carry the pin 2 and pin 3 data for RS-232.

As Jack said, it's important to only connect pins 2, 3, (both data) and 
5 (ground) to the KRC2 circuit because the other pins of RS-232 are 
electrically incompatible with the KRC2.

Subject: [Elecraft] OT: DIY Tilt-base for Loop Support or Antenna Mast
Message-ID: <56DF52D5.2070901@montac.com>

Putting up a multi-band, horizontally oriented loop and I have ZERO
trees in my yard.  I am borrowing trees from my two next door neighbors,
but I needed to supply one support for a delta config (yes, I'd prefer a
square).

Didn't like the commercial telescoping masts available, so I designed my
own (another thread if anyone is interested...  it's pretty cool and
well within average DIY skills).
Then I decided that I would like to bring the mast/support down for
maintenance WITHOUT having to collapse it, so I decided to use a
tilt-base.  Those available for a mast lower section diameter like mine
were either wayyyy too expensive, too flimsy, or just plain cumbersome.
So I decided to design and build my own.

Here is an ISO picture of the completed base with the 2" RMC
nipple/coupler installed in the upright position:

*http://montac.com/images/antenna/tilt_base_iso.jpg*

Here is an elevated front view:

*http://montac.com/images/antenna/tilt_base_front.jpg*

Here is a view with the top rear bolt and safety pin nut/washers removed
simulating prep for lowering:

*http://montac.com/images/antenna/tilt_base_top_pin_pulled.jpg
*
And finally, here is a view with the "mast" in the horizontal position:

*http://montac.com/images/antenna/tilt_base_horiz.jpg
*
The base plate is 12" x 12" x 3/8" hot-rolled steel.  It will be mounted
on a 10' x 20' x 6" concrete slab ("patio") directly behind my house
adjacent to my "shack" window, using 1/2" concrete anchors set full
depth in the slab.  The holes for the anchors are located inboard of the
edges by 1/2" to leave plenty of material to support them while
spreading the load.  The base plate will be leveled on the slab to
compensate for the slab drainage pitch and isolated from the concrete
using a concrete patch material to avoid corrosion on the bottom surface
over time.

The upright "c-channel" was constructed of 3 pieces of 3.5" x 5.5" (nom.
cut to fit under coupler on nipple as installed) x 3/8" hot-rolled
steel.  The back was specifically left full size to minimize cutting,
provide more strength and surface area to weld (welding later). The
assembly is located on the base plate to center the mast center
coincident with the plate center for load distribution.

* The plan called for a radius cut on the "ears" to clear the coupler on
tilt down, but I simplified it to a simple straight cut from the
nipple/coupler mid-line to the front edge to provide sufficient clearance.

* The plan called for a machined relief cut in the inside surface of the
back plate to clear the rear arc of the swinging nipple, but I
simplified that by simply removing minimally required material from the
nipple in a small arc/radius to clear the un-machined back plate.

* All three fasteners are 1/2' x 4" 316 SS with top-locking eccentric
nuts and 316SS washers.  The washers are technically unnecessary because
the through holes in the "ears" are only +0.004" over the bolt size, but
I am using them for "good measure"  There will only be 1 or 2 per side. 
The extras in these images are to allow me to tighten the nuts without
engaging the lock for repeated fitment (nuts are rated for 5
installations).  The 2 through nipple holes are on the exact nipple
mid-line and result in the nipple being flush with the back plate within
0.003".  This took a lot of math, close measurement with calipers, etc.
and VERY careful setup on the drill press with good quality drills.

* The third fastener is through the ears alone and flush with the front
edge of the nipple as a "safety" pin for tilt-down ops.  The bolt will
be replaced at some point with a pull-pin that will be dummy-corded to
the left base ear with SS aircraft cable to keep it from being
misplaced.  The idea is that the top rear fastener might need to be
tapped out of its seat to remove, and the safety pin will keep the mast
upright. When the rigging for lowering the mast is set, I can rig a
remote pull cord for the safety pin and lower the mast in a 1-man
operation while remaining clear of the drop area and the base itself,
reducing chance of injury (the mast is HEAVY!!!).

* Currently, the entire base is cold galvanized to protect the bare
steel underneath (as all scale/oxidation was removed for machining and
welding).  I will likely take it to my local coating shop and have it
sand-blasted and either hot galvanized, zinc chromated, or powder-coated
to protect against corrosion.  Cold galvanizing is NOT for moving parts
or parts on the ground.

Note:  IF this base is used for an antenna mast, I would personally add
an adjustable mast rotation stop to the base plate under the coupler
drop zone to "catch" the mast to prevent the antenna from touching the
ground and/or to stop it at a convenient work height.

WELDING:  Yes, my welds aren't particularly pretty.  I am NOT a welder
and haven't done ANY welding in over 10 years.... so cut me some slack. 
This is probably a lot of gobbledygook to most of you, but is included
to show that a small welder CAN do this job successfully.

This is THICK steel.  I do NOT recommend welding this up yourself... but
I did.  And I did it with a Millermatic 135 (115VAC) MIG machine using
0.023 ER70S-6 wire (old wire that was somewhat oxidized).  Needless to
say, it took some finagling to get good penetration.  here is how "I"
chose to do it:

I beveled BOTH sides of the two ears on bottom and on the back edge.  I
beveled the back-plate on both sides on the bottom edge.  I left
approximately a 1/8" flat "land" to allow for a 0.0625" thickness to
from each side to theoretically JUST allow for touching penetration when
welded as setup for 1/8" steel using 0.023" wire.  The bevel angle was
set at MORE than 45 degrees (about 52 degrees plus/minus) to allow for
better access considering the bevel was meeting to a vertical flat...
bevel to butt joint.

The machine was set to 7 on the voltage knob and 70 on the wire feed
knob...  basically yielding around 90 amps using the 0.023" wire and a
wire feed rate just barely adequate to keep up.  It would have been
better to use 0.030" wire and FRESH, unoxidized wire.  This would have
netted a higher realized amperage (need about 125) due to the wire
supporting a higher voltage before melting, and allowed for a higher
feed rate.

As I didn't have those options on a SUNDAY (no welding supply places
open), I worked with what I had.  I used a dedicated 20 AMP circuit from
my sub-panel and made sure I had a super good ground (put a wad of
welding wire core between the clamp and the cleaned metal base.

Procedure:

1) Tack together and refit the nipple/coupler/fasteners to make sure
nothing moved.
2) Make first pass with a stringer to connect tacks.
3) Grind stringer weld clean and smooth (a la pipe welding)
4) Make multiple fill passes (I only needed 2) cleaning WELL with a wire
brush between passes.
5) Make a final cap weld pass.

I also pre-heated the assembly with my torch to reduce the massive
heat-sinking ability of that much metal compared to the welder's ability
to supply current.

Result was not perfect, but sufficient penetration to make the welds
plenty strong for the purpose.  The base will rip up the slab before it
fails at a weld.

That's about it...  heavy-duty, can be adapted to any mast size,
customizable to mount in various locations, etc.

Have a great evening!

Message-ID: <003c01d179a3$871add90$955098b0$@net>

I had a plan to set up one of my shack K3 rigs as a remote control station
to be used with a K3/0-Mini but have abandoned the plan due to changing
interests and need to raise $$$ to pursue them.

 

This complete package costs $1320 at current Elecraft packaging.

 

This package has only been unpacked for inventory, it has never been
assembled and configured.  It was purchased in August 2015.

 

A complete inventory is available on request.  The K3/0-Mini is s/n 247.

 

I am asking $1150 shipped within USA.  I will accept PayPal, USPS money
order or bank draft.

 

Please reply directly to n1nk at cox.net.

This can be accomplished by any quality SDR with the appropriate
software (there are multiple approaches). There are several newer
SDR hardware devices that are less expensive than the LP-Pan and
sound card combination that are not tied to somewhat unstable
drivers.

Message-ID: <CALQT3yz9XP7=yO0zKL7CWkAR_f3h5_FcUi_pCdUwUpAOxWVcmQ@mail.gmail.com>

Hi folks,

I'm building an Arduino-based mag-loop autotuner, and I have a feature
request for better integration with the KX3. Would it be possible to create
a new mode for the ACC2 GPIO line, to go high when the radio is in
transmitting a carrier in response to a user pushing TUNE, and low at all
other times (specifically including when the user pushes ATU tune)? I'm
open to more sophisticated or bidirectional communication on that line too,
but this seems like an easy place to start.

I don't have a K3, and I don't know which ACC line would be most suitable
for that radio, but if this is a good idea for the KX3, please consider a
similar request for this feature on that radio.

Thanks!

Bruce

Looking on the Elecraft order page, they don't sell a reference

Hi Bill

I know this is not the exact answer to your question but I plan to operate my home K3S this summer from my camping locations using the Verizon network. My solution may work for you too. I bought the PIGREMOTE from PIGNOLOGY and so far have it working within my house. I can send and receive SSB, CW and PSK31 across my WIFI from one room to another. My next step will be to use their recommended Internet address finder to get it to work on the Verizon network. I have two busy volunteering days starting in about 2 hours so I will let you know how that works just as soon as I have time to work on it.

I liked the PIGREMOTE price of about $270 for everything including the cables to hook up to the K3, the WIFI and shipping. They include programs for Windows, iMac and the iPad. I find I like the iPad program best and it will fit my camping situation better but the Windows program works well and I was pleased with it before I set up the iPad and found that to be even more powerful.

I expect to have the K3 be able to work 160 through 10 meters, switch antennas between the vertical and beam and use my separate receive antenna this summer. The only project that I need to build yet to do all that will be a logic circuit to add a loading coil for 160 driven by the ACC jack on the K3.

Look it over and see if it will work for you.

You can look for a GPS disciplined oscillator (GPSDO), an FE-5680 Rubidium 
based oscillator, or look for some of the lesser expensive GPS receiver 
modules that have 10MHz outputs.

A GPSDO can be expensive but there are some more affordable ones if you look 
around. FE-5680's used to be available around $100US (or less if you got 
lucky). Lately the prices seem to have gone up for these devices, and they 
tend to be power hungry. There are some GPS receiver modules that have GPS 
receiver blocks on them made by companies such as Ublox. Take a look for GPS 
receiver devices that are meant to be used as part of a flight control 
system for radio controlled aircraft (or what some people call drones).

I'm using my K3 to control the remote K3 at W7RN.  Works find on CW and 
SSB, haven't tried AFSK, but it might work there too.  I use a WinkeyUSB 
to key the RemoteRig [two pins on the rear RJ-45].

I'm putting an end-fed all-band wire on the back fence for times when 
the remote is down or the station has an on-site effort going on.  My 
Winkey has two key outputs.  Can I connect KEY2 to my control K3 key 
jack and just leave it there?  I'm trying to reduce the amount of 
rewiring of the "wireless" to go from remote to local operation.

Message-ID: <CANAn7wwz6Yh_tFrjiAdV=5cBsamFm+yp_1HmC5LpVicFNPD6AQ@mail.gmail.com>

I have my 2nd receiver tapped and use a Funcube Pro dongle with NAP3
version 5.  The main VFO I use Win4K3 with LP-PAN2 and a Steinburg UR22 USB
192Khz sound card.

The funcube pro is a less expensive option for taking your IF out and
getting your Panadapter working for either your main receiver or a second
receiver, or both.

Due to some limitations of the radio control software in the K3, you can
not get the subreceiver frequency displayed correctly.  What you can do is
watch a second band or up/down the same band, then use A/B to send VFOB to
VFOA for further inspection.  I find it useful for FD to use the K3 on 6m
and 2m in this manner.  I also in a contest can be running on one band and
then S&P with the VFOB.

You could get an LP Pan panadapter (http://www.telepostinc.com/LP-PAN.html)
and this will allow you receive on a second frequency on your computer using
the VFO B knob to tune (distance from VFO A determined by the sound card you
use - panadapter bandwidth can be up to 192KHz).  You can also listen to the
VFO A frequency applying different filtering and noise reduction techniques
to those set up on your K3.

Hi Bill, I too use the Pignology PigRemote to control my remote KX3 and ALS-600 and have done soft some time.  I can control it from a Windows or Mac laptop or tablet, an iPad and an iPhone form home, in the car, in a restaurant or hotel wherever I have internet access.  No computer is required at the radio location nor is any type of specialized radio remote hardware at the Florida location.

The Pignology software supports the Elecraft hardware VERY well and cost very little. Total cost under $300 for everything.

Take a look at my QRZ page (k9jri) for a picture of it.

After no response from the group I sent my question to support and received
the following reply:

"There are no compatibility issue with the K3 controlling the K3S (or K3S
controlling the K3). The K3 will react as if it was the K3S."

Once again, great customer support.

Udo & Kevin,

Thanks for the reply. I hadn't researched any of the options, I 
thought the K3EXREF was all I needed. Now that I have a better idea 
what to look for, I'll find something. I just need to be sure it fits 

what the requirements are.

I'm surprised to find almost all the sources are from China. I know 
they are trying ever more to make better products but something as 
precise as a 10 MHz standard that will be connected to my K3s, 
concerns when me buying from an unknown manufacturer. QC is always a 
concern. Sure wish there was an affordable kit with the proper 
connections that was available.

If anyone has a 10 MHz reference signal source that works fine with 
the K3 & is excess to their needs, please contact me off list.

Thanks & 73,

Gary

You can't beat a surplus Trimble Thunderbolt. Everything in one small box, 
the power supply is available on e-Pay as well as the antenna.

Once upon a time they were cheap, like $20 cheap. But the supply is drying 
up. They are still a bargain at $125 though.

I bought a few when they were plentiful.

As a casual observer of this thread - does the oscillator have to be
precisely 10 mhz to a zillion decimal places  OR does it just need 
to be close to 10 mhz and verrrrrryyyyy stable ? 

Years ago hams used to build 10 mhz xtal 
oscillators/buffers  - put them in  a thermos bottle - dig a post hole
and bury the thing about 4 feet deep - it was pretty stable
just xtal aging and needed lo noise stable DC.

You can look for a GPS disciplined oscillator (GPSDO), an FE-5680 Rubidium 
based oscillator, or look for some of the lesser expensive GPS receiver 
modules that have 10MHz outputs.

Hank,

It needs to be 10 MHz and very stable.
If it is not right on 10 MHz, it will still lock, but the K3 frequency 
will be off as much as the reference is different than 10 MHz.

73,
Don W3FPR

The Trimble Thunderbolt is locked to the GPS system, which derives it's
reference 
from Cesium standards initially, but I believe now they have Rubidium
standards 
that are locked to a master reference.

Someone who knows more about the GPS system can chime in on this.

In any case, the T-Bolt 10 MHz reference output is about the best you can
get 
unless you want to spring for an HP Cesium standard or maybe a Hydrogen
Maser ??

I have two active ones plus one I built using the N1JEZ design. I have a
third 
one boxed up with a power supply and distribution amp that I can loan out to

friends.

The Ublox GPS units (like the Neo-6 and NEO-7) are not great for this 
application.  Their master oscillators are an oddball frequency (as far as 
freq standards go, IIRC 48MHz?).  That doesn't divide evenly to 10MHz, so 
there is some jitter component at 10MHz output.  Not what you want for a 
reference signal.

I've used a used commercial-grade GPSDO that I found used, and an HP3801A 
from ebay, both less than $100.

I've also purchased rubidium-based units, Efratom LPRO-101 from ebay for 
about $75 each.

There are several other GPS-based thingies that aren't "disciplined" for 
pretty good prices.  The older Trimble units are usually good.  Hams Summers 
of QRPLabs.com sells a QLG1 for about $23 that seems to be usable - I think. 
I've got one for my QRP Labs beacon.  You might want to look at the specs 
for the SKM1 GPS module on his board.

There are many designs for GPS disciplined oscillators, and many inexpensive 
GPS receivers out there.  Make sure their 10MHz output is stable.  However, 
if you want "portability", or your shack can't easily see the sky, you might 
want to check out the various rubidium oscillators instead.  I'm sure you 
can find a TON more info on the timenuts forum.

Also be careful with the 10MHz reference signal distribution, it can play 
havoc with the 30 Meters band (and 10MHz WWV), especially it it's a ratty 
square wave.

based oscillator, or look for some of the lesser expensive GPS receiver
modules that have 10MHz outputs.

A GPSDO can be expensive but there are some more affordable ones if you look
around. FE-5680's used to be available around $100US (or less if you got
lucky). Lately the prices seem to have gone up for these devices, and they
tend to be power hungry. There are some GPS receiver modules that have GPS
receiver blocks on them made by companies such as Ublox. Take a look for GPS
receiver devices that are meant to be used as part of a flight control
system for radio controlled aircraft (or what some people call drones).

I have just ordered a BL2 balun kit.  I assume it is a voltage balun
switchable 1:1 to 4:1.  I did not see any notation whether it was a current
or voltage balun.  One of the things I need is an enclosure for the balun.
I would be interested in what others have used for enclosures, especially
ones that are waterproof.

Hi Gary,

there is several options how to solve the 10MHz ref. source for your K3.
Some of them has been mentioned over here already.
In all cases you can find Pros and Cons...
In fact you need to know what is your own prefference > precision,
simplicity, consumption, price etc.

Try to look for some information about the solution using FE-5680A Rubidium
standard here:
http://ok1rp.blogspot.ch/2014/07/fe-5680a-rubidium-standard.html

then you can consider the pluses and minuses and comapre it with another
solutions.

The FE-5680A units are still available on eBay (my own I found for $69 incl.
shipping years ago) now at around $100 I guess but these units are heavily
used in BTS stations for long time (Base Transceiver Station in Base Station
S(ubs)ystem of GSM cellular network) 
These units are retired based on pre-calculated life-time and now are
available as surplus parts on eBay. 
It not means that it will not work but some units will make good job for us
for several year and some unit will fail in short term unfortunately. It is
hard to estimate or anticipate.

My unit is purchased on eBay in 2013 and work perfectly but I can recommend
to ask seller how old the offered unit is and focuse on as young as
possible.

Another "Cons" for somebody (not my case) can be to consuption as these
units (depends to type) needs 15V to 18V @ 1.8A peak and 0.7A steady-state.

Even although all what I said can sounds bad I can recommend it as more or
less cheap and good solution.

More informations you can find on Doug's, VK3UM pages (RIP)

If you just need a 10-MHz reference then you do not need a GPSDO.  A 
simple surplus OCXO (oven controlled xtal oscillator) off e-bay will 
suffice.  I bought a one for about $45 initially (Morion).  Since 
then I bought two sine-wave OCXO for $25.  You do need to supply very 
clean 12v dc for most of these and a stable bias 0-5v for tuning the 
OCXO to 10.000,000 MHz.

Short term stability is 5 E-12 which will do fine with the 
K3EXREF.  The TCXO is the limiting factor for frequency in the K3 so 
really no need for GPS accuracy.  If you are feeding a PLL system 
then the GPSDO will be better.

I use a LM7805 to 100K 15 turn pot to supply the tuning bias.  Adding 
a medium value electrolytic cap before the OCXO is extra insurance to 
eliminate any ac ripple or noise from modulating the OCXO.  One could 
also float charge a battery to feed the OCXO which also damps out any 
ac.  Why I mention this is I was using a 1.5A RS wall wart charger 
initially until I was told I had 120-Hz spurs on my signal.  There 
was about 0.3vac ripple from the so-called 12v wall wart.

I could have built or bought a clean low power 12v PS but I just 
hooked the OCXO to my 50A Astron PS.  No spurs, now.

To set up the OCXO use a good frequency counter or net the oscillator 
to WWV 10-MHz (if you can hear it).  I have a Rubidium source that I 
use as my standard and measure with a microwave frequency 
counter.  But that is not needed for basic use on HF/6m with the 
K3EXREF.  Note that OCXO will drift off frequency about 1-Hz in six 
months so regular checking a couple times per year is needed.  GPSDO 
does not need this.

I ordered the K3EXREF and thought it was the oscillator itself which
would provide the external signal source to the K3s. I thought this
was all I was going to need but I see now that is not the case.
Looking on the Elecraft order page, they don't sell a reference
source.

What external 10-MHz reference signal source might I find get that is
not terribly expensive that will do the proper job and allow me to
get this working?

Lyle,

Thanks.  I learned something.

That does make sense as the synth are under MCU control so that would 
be the easy way to compensate TCXO drift.  REF CAL display then 
merely displays the TCXO frequency as measured against the external 
10-MHz reference.  Actual frequency is compensated by the synth.

One can measure the TEST mode output directly into a frequency 
counter (BUT DO NOT transmit full power).  I can measure the K3 10w 
signal by using a 2m rubber ducky connected to my counter and held 
next to the K3 chassis.  Running higher power is even easier to 
monitor on a counter.  Transmit in CW mode.

Almost.

The TCXO has no control input and is not tuned; it is only measured.

The measurement information is passed to the radio's MCU which then uses
the data to determine the correct value to command the synthesizer(s),
drive the REF CAL display, and so forth.

Gary,

just one more thing...

If you will decline the Rubidium standard solution and you will thinking
more about the GPSDO then my own recommendation is for James, G3RUH
solution. It is "ready to go" box, very nice built. Not cheap, but no
Chinese crapy and it is using new and very clean AXIOM40 OCXO. (no need to
solve the distribution amps issue etc.)

http://www.jrmiller.demon.co.uk/projects/ministd/frqstd.htm

More links for your inspiration how it can be solved are here:

If you want to save the 300$ you can operate remotely from laptop, iPad or iPhone using a surplus windows machine (I'm using a cheap notebook) and all free software. I have done that for over ten years now with K2 or K3 using KPA/KAT500 and keying with a pair of Winkeyers. Check my QRZ page if interested.

Terry,
I beg to differ.  I did extensive comparisons of the UBLOX units with my 
Rb.  There is also an article by an LA ham concluded the same.

Yes there is jitter, however it's peak amount is fraction of the 1 Hz 
step the XREF corrects for.

If you're interested I'll send you a plot of deviations.

Terry,

The BL2 is a current balun.
You will have to depend on others for an enclosure, I don't use one.  
W8FGU has an enclosure, but it is not weatherproof.

Message-ID: <56E1CE18.7000604@nycap.rr.com>

A while back there was some information about using a 48 key keypad for 
controlling the K3. It was done by connecting the keypad to the P3 
(expensive extra board required) and controlling the K3 by triggering 
assigned macros in the P3 that in turn are sent to the K3 for rig 
control. Has anyone had success using the keypad connected directly to 
the K3 for rig control (serial port)? I envision that each key would be 
individually programmed with an instruction, rather than keying a memory 
position in the P3.

Seems to me that this could be a cottage industry.  I would gladly pay for 
software that could implement this.  I have quite literally aggravated an old 
rotator cuff problem (surgery once) tuning and pushing buttons on my 
ergonomically-challenged K3.  I'm ready to rearrange the shack to put the radio 
on the left and have already trained my left hand to run the mouse.  A 
"flat-on-the-desk" keypad would be wonderful.

I use a Pigknob with great success. You can easily program it for any 
command(s). Unfortunately, it is limited to only 8 buttons. It does also 
do the VFO.

I too am limited in motion and like to run the rig from something that 
is right on the edge of the desk.

I have been chasing a mouse with an older (free) version of HRD for 
several years. Not perfect, but pretty good. I was hoping the new HRD 
versions would add features and correct some problems. Sadly, not so - 
so I stay with what I have. I am only interested in rig control - not 
all the other stuff that HRD does.

There are some other programs out there, but be careful. I have 
experienced complete loss of my presets using them (my menu selections).

The reason I would like to go direct to the K3 is to avoid the extra 
expense of the P3 board. The keypad is available with a serial cable.

This sounds like a great project for an Arduino. The problem I see is an "easy" way for the end user to be able to let the Arduino know what command each pushbutton represented. Maybe a file on an SD card that held those variables? The op would only have to populate the file on the SD card.... Humm.

I've just installed an svga card in my P3 and I'm trying to get it to work with a 7 or 8 year old apple display monitor. It has a DVI male connector so I purchased a DVI to VGA adapter. But the setup doesn't seem to work. Any idea why? Any experience with this monitor and the P3 or is there a comparability problem?

One potential problem is that a DVI monitor is not necessarily designed to work with a SVGA video source.  DVI uses digital signals whereas SVGA uses analog signals. In some cases, a DVI source in fact produces both analog and digital (on different pins) which is why a DVI-to-VGA adapter may work with a DVI source connecting to an analog display.

BTW, which Apple Monitor are you attempting to connect?

In your case, you have an analog source attempting to provide video to a digital monitor.  I?m not aware any pure SVGA source being compatible with an Apple DVI monitor.  The P3 SVGA card expects to be connected to a VGA display, not a DVI.

On a different note:  I trust you?re having fun with your setup in SE Georgia. My Elecraft setup is working well in Folkston and I access it remotely to check into the Sunday AMSAT Net from Massachusetts plus listen around the bands.

A while back there was some information about using a 48 key keypad for 
controlling the K3. It was done by connecting the keypad to the P3 
(expensive extra board required) and controlling the K3 by triggering 
assigned macros in the P3 that in turn are sent to the K3 for rig 
control. Has anyone had success using the keypad connected directly to 
the K3 for rig control (serial port)? I envision that each key would be 
individually programmed with an instruction, rather than keying a memory 
position in the P3.

Hello,
     As part of my work designing and maintaining a remote station, I can
think of several ways to use a tower-mounted RF-actuated programmable coax
switch. So I'm wondering how hard it would be to add an optional external
coax switch for use with the KAT500? This would offer a couple benefits -
ability to tower-mount a coax switch (but maintain control of that switch
via the KAT500 circuitry and utility program), and it would increase the
number of available antenna ports from the current three to perhaps 6. 
     If this option were available, it could be implemented using a small
RF-sensing control box which would allow the KAT500 to remain as-is. The
KAT500 PC Data line would then run through the external control box to the
user's computer so that the utility program, once updated, would be able to
show coax switch status and allow the utility to program how the
tower-mounted switch responds. The user could hook the external RF-sensing
control box to ANT1 on the KAT500 (so ANT1 would be the position to select
if/when one wanted to use the tower-mounted switch). A switch control line,
and the RF coax would be the two lines running to the tower-mounted switch.
     I'm posting here because it seems like the circuitry to sense frequency
and actuate the switching is already designed, and could be mostly
duplicated in the external RF-sensing control box. Would anyone else be
interested in such a "smart RF coax switch" option?  I suspect the numbers
may not support this as a new product, but I am curious, as what I would
like to see is frequently out of phase with what others need ;)

I appreciate the replies to my question about sourcing a 10 MHz 
external reference for my K3s. I didn't realize I needed more than 
the K3EXREF to gain this accuracy and thanks to these replies, I now 
better understand what will and what will not work. While I would 
prefer to be able to buy a satisfactory GPSDO or kit from Elecraft, 
it isn't an option at this time and not knowing if one is on the 
Horizon, I must look elsewhere to find one. 

What makes it a more difficult choice is understanding what values 
are sufficient and what is excess; some of these devices are in the 4 
figures and some used are less than $40. I was about to buy a $40 
used TCVCXO but learned they need to be recalibrated to maintain 
their precision and I having no equipment to do this, one of the more 
expensive options apparently is a better solution.

Apparently the low cost GPSDO are an affordable way to go for long 
term accuracy but which one to get? Some apparently have jitter from 
poorly isolated interference due to the proximity of their 1pps 
Square wave functions but is that jitter something to affect their 
function as a frequency standard for the K3/K3s, I have no idea. Is 
there an advantage in accuracy by using the GPSDO linked below over 
the BG7TBL versions from China? $226 & needing antenna and power 
supply for low jitter vs $150 for everything but with higher jitter? 
Is a square wave output as useful as a sine wave, both are available 
in the BG7TBL versions. For an external reference function with the 
radio, what is excess? I have no idea.

Apparently the components in the BG7TBL versions change due to their 
supply of surplus components; the versions are the manufacturing 
date, and not all work identically because of this. But does it 
matter, is the least desirable GPSDO still adequate to do this job 
properly? Engineering is not my field and there's a lot to sift 
through in reading peoples discussions and opinions when most of the 
comments are not directed to effectiveness with the K3/K3s.

There are other options available but apparently the prices have gone 
up recently and some once viable options are now not available or 
highly priced, even when used. If Elecraft is not going to make an 
option available for purchase, what would probably be helpful would 
be a listing here or on someone's page, of what kind of affordable 
units are ideal for the 10 MHz reference source and what is 
un-necessary overkill.

Thanks again for the replies, its always fun to learn new things.

73,

Gary

Hi Gary,

Because the K3 only -frequency- locks the frequency to within about 2Hz you won't notice any difference between them. Similarly because the K3 TCXO isn't -phase- locked to the external reference any phase noise on the reference won't affect low phase noise of the synthesiser in the K3.

So buying a kilobuck reference isn't going to gain you anything at all. 

The BG7TBL or the Leo Bodnar unit would be my choice. (I have both here and a Z3801A) . The Leo Bodnar being a nice low power consumption unit, and a lot more versatile than just a 10 MHz GPSDO. It has many other uses around the shack, covering up to 800 MHz.

You may want to have a look at this for some background on real world frequency stability, and remember that the K3 isn't phase locked to the external reference and is only going to be within 2Hz.

Bob,

Most probably a switched mode power supply somewhere locally, almost everything we see repeated at regular frequency intervals like that are harmonics of SMPS. Often up to VHF unfortunately :-(

Have you tried switching off the house breaker and listening on batteries to be sure it isn't self inflicted?

It could be anything from a mobile phone charger to a grow light ballast.

Yet another example of a switch-mode power supply.  Here's a preliminary

I am a tad confused over this issue. Perhaps I need to read up on how
Elecraft 
controls frequency.

My understanding on a "Locked" frequency would infer that the result would
be 
 a LOT closer than 2 Hz @ 10 MHz. 

Is there a detailed description of the process somewhere that I could read ?

Hi Fred,

Change your RRC Control setting under Keyer settings
Side tone -db [50-0]:
Set it to more reasonable value, 0 is the loudest, value is in "- db" :-)

Set it to 45 or 50 and you must see the difference

Hope it helps

Hi,

in case of such amount of bucks is planned to be spent for "ready to go"
unit then Leo Bodnar is the very good choice but I preffer this "Low Jitter
/ Low Phase Noise" model:

http://www.force12inc.com/products/gps-locked-precision-frequency-reference-low-jitter-gps-clock-450-hz-to-800-mhz-output-custom-low-phase-noise-xtal-version.html

I know that it will not be utilized fully in case of just locking the K3 but
it can be used in much more application in ham shack like MW etc.

There was a thread about this recently (last few days).

The instructions for the K3 give the spec as up to plus and minus 2Hz at 10 MHz.

Go into the RRC's web menus and click on "keyer settings", then go to 
"side tone" and adjust the db down to an acceptable level.

Subject: [Elecraft] K3 Feature Request
Message-ID: <56E30A72.9050308@k1xx.com>

I use the internal K3 message memories when operating as DX in an ssb contest.  
One of the biggest problem I face is the delay both in initiating the message (from an external application) and the delay between the end of the message and back in the receive mode.  From experiments, both of these delays seem due to the time between the button presses on the K3's front panel.  Granted, there may be some time between pushing the appropriate F key in the application (Wintest).  But, this only addresses possibly the initiation delay.

Could some method/application be added to upload an externally generated audio file, which uses some standard format, into an arbitrarily assigned message?  Or, at the very least, provide a means to change the K3 between receive & transmit without suffering the delays due to button presses?

For the curious, when running at rates of 300+ QSOs per hour, the delays turn out to be significant.

Dick,

I found the reference to that figure I quoted, it is in the K3EXREF manual:

The K3EXREF option locks the K3's reference oscillator frequency to an external 10 MHz source by automatically controlling the REF CAL function. While locked to the external source, the K3?s reference oscillator frequency is maintained within 2 Hz. Since the K3EXREF does not phase lock the K3?s reference oscillator, the external 10 MHz source has no impact on the K3?s phase noise performance. For best performance we recommend your K3 be equipped with the KTCXO3-1 high stability (0.5 ppm typ.) reference oscillator.

The K3's reference oscillator is 49.380 MHz (+/-) not 10 MHz.

The K3EXTREF uses the external 10 MHz signal to gate a counter
which counts the reference.  That count is then used to adjust
the reference frequency.  Maintaining the 49.380 MHz reference
+/- 2Hz is on the order
of 0.04 ppm.

Subject: [Elecraft] K3 Feature Request
Message-ID: <b5502f1362d6f8bb8e97ea574bf0333c.squirrel@www11.qth.com>

I am curious what you are you using the memories for? I really never
noticed any delay but during 300/hour rates I think it is way easier to
just to speak.

I use the internal K3 message memories when operating as DX in an ssb
contest.
One of the biggest problem I face is the delay both in initiating the
message (from an external application) and the delay between the end of
the message and back in the receive mode.  From experiments, both of these
delays seem due to the time between the button presses on the K3's front
panel.  Granted, there may be some time between pushing the appropriate F
key in the application (Wintest).  But, this only addresses possibly the
initiation delay.

Could some method/application be added to upload an externally generated
audio file, which uses some standard format, into an arbitrarily assigned
message?  Or, at the very least, provide a means to change the K3 between
receive & transmit without suffering the delays due to button presses?

For the curious, when running at rates of 300+ QSOs per hour, the delays
turn out to be significant.

The stuff I have run into that is in the 16 to 18 khz range includes 
furnace /air conditioner  motor controls and  washing machines.

Of course those are intermittent which is also a clue- although 
there are some furnace/A/C blowers that stay on at low speed all
the time for circulation.  

If you have a P3 - decrease the span  and most of the newer stuff
at certain parts of the cycle will actually be several spikes in
each group of noise.

Can someone help me understand the "noise" on 17m - and elsewhere - 
right now? It repeats every 17kc, very strong. Perhaps some sort of over 
the horizon radar? Is it general or just something in my neighborhood? 
Thanks much.

Hi Dick,

There may be a little misunderstanding as to what "locked" means in this implementation. It isn't the same as phase locking an oscillator to a  high standard reference that's true.  On the other hand it is more than good enough for almost any HF application, and it has the huge benefit of not risking degrading the excellent phase noise characteristics of the K3' synthesiser.

Basically any accurate 10 MHz source (calibrated occasionally) that is temperature stable like an ovened crystal oscillator or a Rubidium source could be used for this, however many already have a GPSDO and there are plenty surplus ones as well as fairly inexpensive ones that would be useful for other purposes that can be obtained. 

Some people including myself have a thing about frequency accuracy, and it is easy to become over obsessive about it ;-)

I am more concerned with limiting any frequency drift so that narrowband digital modes are not degraded in sensitivity, especially at VHF and above.

While locked to the external source, the K3?s reference oscillator frequency is maintained within 2 Hz. Since the K3EXREF does not phase lock the K3?s reference oscillator, the external 10 MHz source has no impact on the K3?s phase noise performance. For best performance we recommend your K3 be equipped with the KTCXO3-1 high stability (0.5 ppm typ.) reference oscillator.

I am not arguing about that calculation Joe, it's proof that you don't need GPSDO accuracy as if will be several orders of magnitude better than that.

Note that 2 Hz refers only to the reference oscillator which is close to 
49,380 kHz.  That is about .04 ppm, or about 10 times greater than the 
specification for the high stability (optional) TCXO.

The frequency accuracy at HF will also be .04 ppm - at 10 MHz that is 
0.4 Hz, at 20 MHzit is 0.8 Hz and so on.

Message-ID: <19FB34D95DC14640AAC0967C49A46543@tomsPC>

Hello,
The latest release of Win4K3Suite is now available.  In this release are new graphical S-Meters for the K3, K3S and KX3. In addition, this release now offers cross hairs for the spectrum scope.
Win4K3Suite is a comprehensive control program for the Elecraft 3 series products and supports all equipment such as the KPA500, KAT500, P3,  and KXPA100 as well as  LPPAN.
Win4K3Suite has a built in serial port router that works with ALL third party products both software and hardware.  As long as they work with the Elecraft radios, they will work with Win4K3Suite.  There is no need for LPBridge.  This solution is 100% stable and robust and can handle any contest you through at it.
Win4K3Suite also works with RemoteRig and allows streaming of LPPAN video from the remote site: (Please see https://www.youtube.com/watch?v=8?Vk2WWLok courtesy of Mats SM0FPR) 

Read the latest reviews here:http://www.amateurradio.com/win4k3suite-added-to-shack/

You can see some videos of Win4K3Suite in action here: https://www.youtube.com/results?search_query=Win4K3Suite

There is a 30 day trial available at va2fsq.com

Just tried Tom's latest software. HA, I didn't read the documentation fully
obviously and discovered I could not use the panadapter display without
having LP Pan or a Softrock or a P3.
I have a sound card and incorrectly assumed I was good t go, dear oh dear,
must be getting older by the day at a faster rate than I expected :-(
The K-Line minus the P3 is installed in the motorhome and just no more room
available for more hardware.
Disappointed but hey, life is full of minor setbacks.
Looks like a great program but sadly not what I can justify buying for now.
Thanks Tom for what looks like a terrific interface, back to DX Labs suite
for now.

Gary,
     If you are using a KX3 rather than a K3 or K3S, you need only the 
sound card.  The KX3 gives you baseband I&Q data on a connector on the 
left side of the radio.

Here's noise from my neighbors new washing machine (Samsung).? http://www.slickpic.com/users/GeneGabry/albums/N9TFHamStationPhotos/?wallpaper&viewer#11792105 
Repeats about every 17Khz. From about 20Mhz-22.5Mhz. Most of all the RF pollution in my neighborhood generates garbage on 15m. Have not seen any yet of 17m. At least the washing machine garbage only lasts for about 60 minutes two to three times a week (when I'm in the shack on 15m). 
? 
Just wait until buck/boost DC-DC converters and switchers are deployed more prolific at 1Mhz and higher. Company I work for makes the?line choke and power inductors used in those switchers. They are worse noise generators than the lower frequency switchers 50khz-500khz. It's only going to get worse :(

The stuff I have run into that is in the 16 to 18 khz range includes furnace /air conditioner ?motor controls and ?washing machines. 

Of course those are intermittent which is also a clue- although 
there are some furnace/A/C blowers that stay on at low speed all 
the time for circulation. ? 

If you have a P3 - decrease the span ?and most of the newer stuff 
at certain parts of the cycle will actually be several spikes in 
each group of noise.

----- Original Message ----- 
Can someone help me understand the "noise" on 17m - and elsewhere - 
right now? It repeats every 17kc, very strong. Perhaps some sort of over 
the horizon radar? Is it general or just something in my neighborhood? 
Thanks much.

Subject: [Elecraft] 10 MHz external reference - GPSDO
Message-ID: <201603112130.u2BLUMj0013102@mail40c28.carrierzone.com>

Joe and all interested in the EXREF:

OK ... but most will not measure the 49.380 TCXO 
directly*.    *though REF CAL displays this.

What I think most want to know is how accurate their operating 
frequency will be.  I performed rigorous measurements as beta tester 
of the EXREF (unfortunately my website was hacked a couple years ago 
and I did not recover the beta-testing data page).

First one needs to realize that the TCXO establishes the basic 
stability, so choosing the TCXO-3 over the TCXO-1 will provide better 
stability and accuracy (these are two different things).  I bought 
the TCXO-3 with my initial K3/10 purchase so the rest of what I say 
is with the better TCXO-3 installed (if frequency is important then 
that is first thing I recommend updating).

Mostly, I use 28-MHz as a testing frequency since it is my VHF 
transverter IF.  On 28-MHz with only the TCXO-3, I see 14-Hz 
inaccuracy.  This 14/28000000 = 0.5 ppm (I think this is better than 
Elecraft specs the TCXO-3).  Adding the EXREF I see 2-Hz which is 
"about" 0.1ppm.  Measurements on 50-MHz are proportional.  I see 3-4 
Hz accuracy using the EXREF.

So going lower to 10-MHz I measure 1-Hz or less inaccuracy.  Due to 
the slow drift of the TCXO's, stability is same as accuracy (or maybe 
better).  So all ham bands lower than 10-MHz show less than 1-Hz 
(basically I measure zero error).

Read below for optional background in my measurements-----------
I am measuring with a high-end mw counter able to count up to 26-GHz 
and has an internal TCXO reference or can take an external 10-MHz 
reference.  I also have a LPRO Rubidium source which is rated +/- 5 
E-11 stability.  I find measurements using either the counter 
internal TCXO or the Rb source are identical when measuring under 
50-MHz signals (speaks well for that TCXO).  I have to wait at least 
30-minutes for complete warm-up stabilizing of the Rb source so 
usually for normal frequency checks I just run the counter with internal TCXO.

MY station 10-MHz standard is a Russian surplus MV62 Morion OCXO spec 
+/-5 E-12 (note it is more stable than my Rb).  But the OCXO must be 
calibrated as it is voltage tuned.  I use the counter/Rb for 
that.  Long-term (measured in months) stability of my OCXO is only 
+/-5 E-5 so I figure that I have to check the OCXO against the Rb 
about twice/year (never been more than 1-Hz off in 3-years running).

The counter can only count to 1-Hz so measuring less than a Hz is not 
possible.  There are sw to make such but I have not gone there (yet).

I build transverters up to 10-GHz which use PLL LO's which actually 
lock to the 10-MHz reference.  I have noted that I can adjust my OCXO 
when measuring 10,224.000,000 MHz to bring it closer to 10-MHz 
because any sub-Hz error is multiplied in the mw LO multiplier 
chain.  Something I cannot do if directly measuring the 10-MHz 
reference.  Of course this is "nit picking" for setting the OCXO for 
use on HF/6m with the K3EXREF.

One caveat in using a Rubidium full time as reference.  They have a 
finite life-span and more expensive (and probably harder to find once 
one fails).  So I only run my Rb for high accuracy checks and "lock" 
for daily use to my $45 or $25 OCXO.  My OCXO runs 24/7 from a 17AH 
battery which is float-charged from a good 12v PS.

The K3's reference oscillator is 49.380 MHz (+/-) not 10 MHz.

The K3EXTREF uses the external 10 MHz signal to gate a counter
which counts the reference.  That count is then used to adjust
the reference frequency.  Maintaining the 49.380 MHz reference
+/- 2Hz is on the order
of 0.04 ppm.

Granted, there may be some time between pushing the appropriate F key in the application (Wintest).  But, this only addresses possibly the initiation delay.

Jimmy,

If all noise were equal, there would be an easy answer (and no need for 
the various settings).
But the truth of the matter is that there are a huge variety of 
different noise sources - rise time, duration, settling time, amplitude, 
etc.
You will just have to experiment to find the best setting for each kind 
of noise you are dealing with at the moment.

Oliver, I was wondering about this, I guess it is just that the short term drift is lower so it won't drift as much between frequency measurement corrections which are made for 1 second every 4 seconds according to some info recently published. I doubt it matters much though. I would be tempted to try it with the standard TCXO first.

Maybe someone from Elecraft would like to comment.

Subject: [Elecraft] Field repair of blown K3 front end?
Message-ID: <56E43790.10508@tx.rr.com>

Due to an unlucky combination of station configuration and a bad TX gain 
calibration in my K3s (since corrected) I've managed to burn out 
something in the front end chain in my second station K3. I've verified 
the problem is in the signal path between the ATU inputs and the input 
to the main receiver. The Sub receiver is working correctly when 
connected via the AUX RF input connector, but dead in normal split mode. 
I've had a look at the schematic and can see a couple of probable points 
of failure.

But... I wonder if anyone else has encountered the problem and done a 
successful field repair. I'd have no particular trouble replacing one or 
two parts on the main board, but without a board layout it would take a 
fair amount of effort to find the suspect parts. I'm also not interested 
in completely dismantling the radio if that's what it would take to 
effect the repair.

Has anyone else found and fixed such a problem? I'd be very interested 
in hearing your experience.

I suggest you contact K3support - they can likely give you a small 
number of probable failure points.  That will allow you to choose field 
repair or send it to Watsonville.

Randy,

Is the main RX dead all the time (when using only Main RX - Sub RX
off)?

Two quick things to check ...

1) if the Main RX is dead all the time and you have KXV3/A/B boards
    in each rig, swap them.  If the problem moves with the KXV3, the
    problem is most likely D5.

2) If the Main RX works if the Sub RX is off and you have KRX3 in
    in each rig, swap the SUB IN boards.  This eliminates an issue
    with T1 (the splitter) and D1/D2 T/R switch PIN Diodes.

The first thing to check is the KXV3 ... If you don't have a second
KXV3, check the schematics for bypassing the potentially defective
one (J66, pins 13 & 15 and pins 8 & 10).

If you have the KXV3 installed, it is probably D5.  I checked the 
Mouser part number for the heavy-duty replacement, and it's still 
good.

Subject: [Elecraft] Field repair of blown K3 front end?

Due to an unlucky combination of station configuration and a bad 
TX gain
calibration in my K3s (since corrected) I've managed to burn out
something in the front end chain in my second station K3. I've 
verified
the problem is in the signal path between the ATU inputs and the 
input
to the main receiver. The Sub receiver is working correctly when
connected via the AUX RF input connector, but dead in normal 
split mode.
I've had a look at the schematic and can see a couple of probable 
points
of failure.

But... I wonder if anyone else has encountered the problem and 
done a
successful field repair. I'd have no particular trouble replacing 
one or
two parts on the main board, but without a board layout it would 
take a
fair amount of effort to find the suspect parts. I'm also not 
interested
in completely dismantling the radio if that's what it would take 
to
effect the repair.

Has anyone else found and fixed such a problem? I'd be very 
interested
in hearing your experience.

Subject: [Elecraft] K3s Utility and Programmable Macros??
Message-ID: <56E458B0.3000903@4email.net>


Attempting to set up K3s to do the following as per example in KE7X
manual, p 212, under Macro Sequencing. His example is to program Macro 4
to change the AGC THR to 020 and Macro 5 to AGC 012 by using a Tap of
M1.  I do not wish to lose the ability to send cw with M1 so wish to use
M4.

Here is my coding for:
Macro 4:  MN074;MP020;SWT14;MN110;SWT27;SWH41;MN255;

Macro 5:  MN074;MP012;SWT14;MN110;SWT24;SWH41;MN255;

When I test, via the Utility using Macro 4 it changes AGC to 020
confirmed by tapping M4.

Same when selecting Macro 5, it changes AGC to 012, confirmed by tapping
M4.

However, repeated taps of M4 simply show the last selection, in case
Macro 5.

Also, after tapping M4 VFOs show 012 in A and AGC THR in B, until
tapping M4 again.  For contesting, this does not work for an efficient
operation.

So, what have I missed with my programming? How can I use M4 to cycle
between 012 and 020 and recover my freq display?

Bear with me because this is from my memory. To the best of my knowledge you have to use the up button and down button to change values and cannot directly enter the value. As I recall Wayne stated it would be added to a future revision but apparently isn't present in the firmware you have which is likely the most recent.

This was a while back so I could be mistaken , however , this is exactly what I was doing at the time.

Excellent! Thanks to Dave, Joe and Don for the useful information. The 
K3 is now on the bench and I'll start work soon. It most likely is D5 on 
the KXV3.

Thank y'all for the quick response.

Must be D5. Removing the KXV3 and shorting pins 8 &10 and 13 & 15 on its 
socket restores full sensitivity to the Main receiver. Thanks again, guys.

Message-ID: <56E48E4D.2020904@montac.com>

Hooking up a Linemaster Clipper Model No. 632-S to my K3s rear PTT RCA jack.

Obviously, the RCA is 2-conductor unbalanced and there is no issue about
which terminals to use on the foot switch for normally open switching.

BUT, I want to make sure the foot switch cable is never an issue for RFI
in or out.

Options:

1) Use one-third of the Component cable assembly I built a long time ago
with nice Canare RCA connectors and L5-CFB coax. (simply cut of one
connector and connect the center conductor to the NO terminal and the
braid to the C terminal) for a quick and free solution.  Kind of stiff
with solid center conductor.

2) Use unshielded twisted-pair 2-conductor (or shielded leaving shield
disconnected) cable. (Have to buy a an RCA connector.)

3) Use shielded 2-4 conductor mic cable (nice and flexible).  I think I
have some Canare Star Quad around somewhere (Still have to buy the RCA
connector).

My question is:

*Do I need to worry about shielding this cable?*  I've got a ground to
pick up the shield in the foot switch, but no place to pick up a chassis
ground cleanly in the back of the K3s...  I could terminate the shield
to the RCA housing at the radio end, but that's going to the connector
board...

Alternatively, I could pull the shield out of the cable near the RCA
cable plug at sufficient length to pick up the chassis ground screw on
the back of the chassis with a ring terminal (not clean, have to buy RCA
connector and MAYBE the cable if I can't find my spare Canare Star Quad
mic cable).

I'm going to use the re-purposed component cable described above for
now, but I don't really want to EVER have to worry about this control
cable giving me issues.  I know it's a small thing, but if I cover all
the small things as I go along, it'll be less work to isolate problems
if/when they crop up down the line.

Jim?

Thanks a bunch!

I?ve never had any problem with RFI on my footswitch, running legal limit from not all that far away.  Any old shielded cable ought to do just fine ? think Radio Shack quality junk.

Certainly no need for Canare in this application.

Clay,

Use twisted pair wire between the switch and the RCA Plug.  The tighter 
the twist the better.
If you use that, there is no need for shielding.
If you do use a shield, connect it to the outside of the enclosure of 
the K3S (the RCA jack is grounded, but not to the outside of the enclosure).

73,
Don W3FPR

Well, I'm not BUYING any Canare cable...  just re-purposing 1/3 of a
component cable I made a long time ago (and haven't needed in a decade),
OR using some leftover Star Quad (if I can find it).  I happen to have
50 NEW, unused Canare RCA connectors in the size required for L5-CFB
cable (think slightly bigger than 1/4", but 75 Ohm).
I realize broadcast quality cable is overkill... simply trying to not
buy new stuff right now if I don't need to... but don't want to "get by
for now" and let a potential RFI candidate into the system.

The REAL question is should I worry about an isolated chassis to chassis
shield, or simply use a flexible coax, or a nice and flexible
twisted-pair mic cable without a separate shield?

Olli,

Referring to page 8 in the K3 Owner's Manual (may be a different page 
for the K3s):

"Frequency Stability  +/- 5 ppm for the TCXO standard; +/- 1ppm for 
the optional TCXO."
TCXO-1 and TCXO-3 respectively mentioned above.

ppm means one part per million (1Hz per million Hz which is 1Hz per MHz).
So frequency drift is proportional to the operating frequency.

1ppm at 10-MHz is 10-Hz;1ppm at 28-MHz is 28-Hz
TCXO-1 provides 5ppm (+/- 50 Hz at 10-MHz and +/- 140 Hz at 28-MHz)
TCXO-3 provides 1ppm (+/- 10 Hz at 10-MHz and +/- 28 Hz at 28-MHz)

the basic frequency stability is determined by which TCXO is 
installed in your K3.

EXREF "essentially" checks frequency drift of whichever TCXO you have 
installed at a fixed time interval of about 4-seconds.  It uses a 
high stability 10-MHz external signal to compare with the 49.380-MHz 
TCXO and corrects the drift that occurs over the 4-second interval.

My measurements of the TCXO-3 show about half the published spec of 
1ppm (14 Hz at 28-MHz) and the EXREF limits the drift of the TCXO-3 
to about 2 Hz.  If I had the TCXO-1 installed, I would expect five 
times as much drift.

So which TCXO you install directly impacts frequency stability.  The 
EXREF reduces that by about an order of five.  The EXREF is not the 
source of stable LO but merely improves what you have 
installed.  Does that clear it up?

73, Ed - KL7UW

The question to ask is what amount of frequency stability and 
accuracy is important for your type of operations.

Why would I need the TCXO-3 instead of the TCXO-1 when using the K3EXREF
if the accuracy and stability is provided by the EXREF? Am I overlooking
something here?

Thanks Ed.

I don't have a problem understanding how the TCXO's work. Maybe I was 
not clear enough. ;-) Taking your example from below, having only the 
TCXO-1 it is surely *not* drifting 140 Hz at 28 MHz within the 4 or 5 
seconds of the EXREF update cycle (same as the TCXO-3 will not drift by 
28 Hz in that time), otherwise the K3 would be a *very* crappy radio. 
;-) Think you are missing the time domain here. ;-)

So my question still stands: What's the real value of the TCXO-3 over 
the TCXO-1 when using the K3EXREF? Unfortunately I do neither have the 
measuring equipment to measure below 1 Hz drift (and I'm not seeing that 
amount with my TCXO-1 only K3) nor a TCXO-3. So will the radio drift by 
0.0014 Hz with the TCXO-1 + K3EXREF within those 4 seconds and the 
TCXO-3 will bring it down to 0.00028 Hz? Then I'm probably fine with the 
TCXO-1 and even the most sophisticated digital modes available. ;-)

Hi Oli,

I agree it looks like there is no point in paying for the TCXO-3 if you have a reliable constantly available 10 MHz external reference. Perhaps they recommend the better TCXO as a better fallback if for any reason the external ref is not available, I can't think of any other reason for it.

Frequency corrections can only be made in 1Hz steps (at 49.380MHz) and
because the higher-specification TCXO should drift more slowly, fewer
corrections should be required. 

But this would only be relevant if someone is using an ultra-narrowband
digital mode that is sensitive to sudden small jumps in frequency.

I think everyone is ignoring something here.  What causes the frequency 
drift in the first place?
It is temperature changes - the designation TCXO signifies Temperature 
Compensated Xtal Oscillator.  It is already compensated for temperature.
If the temperature of the TCXO stays the same, the frequency should be 
stable.

There will be some frequency change during warmup after power on, and 
there will be some frequency change during transmit because the 
temperature inside the box will increase, and will cool during periods 
of receive.
The difference between the TCXO-1 and the TCXO-3 is one of how much.  
The TCXO-3 drift will be smaller than the TCXO-1 over the same 
temperature change.

The drift over the 4 or 5 second correction from the external reference 
will result in a small correction with either TCXO, but it will be 
smaller with the TCXO-3.
Additionally, the frequency drift will be quite small even without the 
external reference unless there is a rapid and drastic change in 
temperature at the case of the TCXO.  These discussions should include 
the temperature change during the measurement periods. to complete the 
picture.

Don W3FPR

Message-ID: <56E57867.7000305@horizon.co.fk>

An observation.

Installed a KIO3B in K3 #345, no problems all working either RS232 or 
USB or both together for CAT and audio.

I use Logger32 and prior to installing the KIO3B my 3GHz clock PC 
comfortably delivered software CW from within Logger over RS232 without 
the need for a Winkey unit.

I have been running the CAT/audio over USB but apart from checking that 
CW keying was working, lights flashing, never listened to it. This 
weekend, however, I did a bit of S&P in a CW contest using Logger macros 
for calling and serial numbering. The CW was rather choppy and 
noticeably staggered at times. So much so that it put me right off my 
stride and I had to resort to hand keying.

For experiment I transferred CAT and CW over to the K3 RS232 port driven 
from a real RS232 on the PC and everything was back to normal. Toggling 
between USB and RS232 equally toggled the "problem" on and off.

Expanding upon this I transferred K3 RS232 to a USB/serial converter, 
original Elecraft with Prolific chip set, and all was still OK. Couldn't 
hear any difference between the native RS232 port and the USB adapter.

My non-PC specialist conclusion is that either the driver supporting the 
KIO3B or all the USB routing action within the KIO3B is causing the damage.

No big deal for me to transfer CAT/CW during my very infrequent CW 
contest activity, just unfortunate that in my cast the one cable 
solution at present isn't.

Any thoughts.

Mike VP8NO

## How do you know that? It may work great at any specific time but 
sooner or later the CW will get messed up.
If you don't have a Winkey USB I'd get one, One USB cable to the PC and 
a key line to the rig. It's supported by all the contesting/general 
logging software. It's also a real good standalone keyer, better than 
the one in the K3(s).

I'd be using the RS-232 port on the K3s for rig control and the USB for 
audio in/out.
The one cable solution may not be.

Same here too, well formed CW from both a K3 and a K3S using the KIO3B

This seems to be the same ole age old problem of relying on a PC keying CW
over a single lead on the RS232 connection or its stand-in (USB).

Over and over ad nauseum, literally thousands of times, this has been
discussed everywhere since before USB existed. Parallel port keying...if
you don't know what a parallel port is, don't feel bad, that's how old this
problem is...it first surfaced so long ago I can't remember how far back.
Parallel port keying seemed to be far less susceptible, with cleaner code
formation. But we all know what happened to parallel ports, if you even
know what one is.

I have not, in my entire life, heard a satisfying answer as to why the
difference.

The very large sample size conclusion: Some people can do that and sound
perfectly crisp, no matter what. Some will get infrequent odd scattered
distortions, that are not enough of a problem to worry about. Others are
driven to distraction with distortions sometimes bordering on hilarious.
Some computers have spells of it that come and go, seeming to correspond to
phases of the moon, alignment of planets, or giraffe mating season.

Some now have excellent results with straight, normal RS232, but USB routed
functions screw up. Others via USB lines do perfectly well. Others STILL
can't use the serial line approach AT ALL. Back in the day, slow CPU speed
and limited memory were often associated with the poor performance.

SOMETIMES, NOT ALWAYS, upgrades to the CPU and memory would fix it. Many
just gave up and went PERMANENTLY to WinKey (way, way cheaper than
motherboards and memory) based solutions, myself included.

The N1MM integration of WinKey devices is at this point flawless. And the
ability now to create tailored PTT, that changes with code speed from a
MicroHam box with embedded WinKey, is priceless.

There has NEVER, in all this decade of fighting this problem, been a silver
bullet solution that fixed the RS232 or USB key line problems. Over the
years I have literally seen hundreds of extended email threads about
dragged-on investigations by earnest and intelligent ham investigators who
never uncovered any solution except throwing bigger and better CPU's at the
problem, HOPING for better performance.

Some people having the problem, while others with similar or identical
equipment having none, simply means nothing. It has always been that way.
One swears that he did this or that and the problem went away, and it
really did go away when HE did that, he's not lying or deluded. But others
try the same solution and nothing changes.

Blaming key line over RS232 or USB problems on anything other than
poltergeist is just plain unfair. It just could be that one insulted Murphy
just one too many times.

I understand that people are trying to make cabling go away. Completely
understand. Been there, done that, failed. Back to WinKey, permanently. No
more wasting time, except my 432nd (or is it 610th, or 326th? I forget)
lifetime email on this frustrating problem.

I have other poltergeist to work on that have no convenient WinKey solution
standing by.

73, and I DO wish you good luck on this one, but don't count on it. PC's
and their constantly thrashing drivers and system program code just have
too many moving parts.

Goes back even further than that, all the way to the semi-automatic bug, in
my opinion. We used to put relay circuits on our keys to get reliable,
click/bounce free keying of our rigs, due to contact bounce and poor contact
in general in the bug's moving parts. I'm going to have to build one of
these for my two Vibroplex's in fact to properly key my elecrafts too,
because of the occasional 7 to 8ohms that appears when making the Dahs....

For me, the only really working final solution to using a computer with my
rigs has been to unhook it from the rig completely. When I go operate, I
have the K2 or K3, a paddle or straight key and a pencil/notebook and that's
it. 

Yeah, I'll never win any contests, but at least I can key the rig. So at the
end of the day, I've found, computers and ham rigs ultimately don't mix.
Unless it's the elecraft panadapter...

Mike,

I am using a K3s but the KIO3B is the same for us and I believe the 
config settings are the same for a K3 with it. I have the USB from 
the KIO3B going to a powered USB hub with 5 devices total on it. I 
have the RS232 from the K3s going to a P3 with the CBLP3Y.

I was working the Stew Perry contest last night, using N1MM and using 

its macros to send CW. The only problem I had in sending is in 
remembering which function key to hit as using a keyboard to send CW 
is new to me (Well... I did have an Apple II+ back in 1981 that had a 

board in it for CW/RTTY but nothing keyboard to send CW since then)

Someone (here, I believe) kindly helped me with the settings to use 
with N1MM & the K3 and be sure if you use N1MM, to have in CONFIG, 
the PTT-KEY set to OFF - RTS. I don't know if any of this will help 
you but I can say that up to 30 WPM, there is no problem on this end 
whatsoever. Your solution will likely be easy to resolve once you pin 

it down.

73,

One approach to reducing the cable mess might be to have the PC 
key the K(X)3(S) using KY programming command, making the 
radio's keyer send the CW.

[My CW isn't good enough to know if it actually works well when 
operating north of 30 WPM.]

Subject: [Elecraft] MMTTY Scope & K3s
Message-ID: <56E5D2B0.19634.14029A98@Gary.ka1j.com>

Something I've noticed that I like very much is the quality of the 
video you see in the MMTTY scope when using the internal card in the 
K3s. 

When I was using a rather decent E-MU 0404 USB sound card for my RTTY 
needs with the K3, the XY scope showed the two opposing ovals as 
white bands that were somewhat thick and "sponge-like" in appearance. 
With the K3s, using the signal generated within the K3, the bands now 
are very tight, very clearly defined and quite thin. All the 
artefacts surrounding the ovals are much better defined, there 
appears to be far less of them and they look like pin points rather 
than tiny puff balls.

It just shows how much better quality the signal is from what the K3s 
generates than the USB soundcard. The Scope software hasn't changed; 
same MMTTY but what an immediately observable difference. And yes, 
decoding is much better too.

Kudos to another well done, by the engineers at Elecraft.

This is an approach that I'm working on since it can be sent from N1MM
function key strings (99% of CW contest sending) and can include rig
control commands and be blended with stuff that N1MM does well and doesn't
need change. Other folks are working on this and probably there will be a
collection of cute techniques that will emerge.

So far, so good.

Message-ID: <1457902808885-7615164.post@n2.nabble.com>

Hi,
Brand new KX3 owner here. I've searched online and through the archives and
there's one thing I can't figure out. It seems like the only time that you
can tweak the NR wet/dry mix is immediately after you turn NR on. Is there
any way to change/tweak the NR level *after* its been enabled, other than
going into the RX NR MENU settings? I'd like to be able to tweak the NR
level in 'real-time' in the same manner that you can tweak the PBT settings.

I'm surprised that I haven't seen this talked about elsewhere. Granted, not
all radios implement this feature well, however newer radios like the Yaesu
FT-991 do a decent job of it.

Thanks,
Tim Henrion

I've wondered the same, only having my kx3 for a few weeks.  One
solution is programming one of the PF keys to trigger the menu item
but thi.s seems like a waste of a PF key if there's another way.

Hello,


I have a KX3. I send the command "PC011;" to it, it does not set the power to 11W - it sets it to the maximum power o/p of the band, be it 15W or 12W. 0-10W no issue. 10W > there is a problem with the latest FW.


I feel there is something wrong here all other commands work fine, when I send a "GET" PC; with the encoder set to 11W I get a return value of "PC011". Hence I am pretty certain there is a bug in the code somewhere. Either that or I have misinterpreted the programmers reference.

One issue of using KY commands is the Esc key will no longer stop a transmission. 

You cannot use Ctrl "K" to type a message to be sent by n1mm.

Why not turn NR Off and back On and make adjustments.

I have read the same discussions about problems with serial-port keying,
and like Guy, have never understood why some people experience timing
problems while others do not.

However, the point at issue here is much more specific: VP8NO's
observation that his KIO3B-USB connection in his older K3 had keying
problems whereas his hardware RS232 connection did not.  I was only
trying to balance that with the observation that the KIO3B's USB port
*is* capable of providing good serial-port keying in the absence of any
other problems.

Sometimes there really is no good explanation because people don't use 
the same hardware, and thus have different drivers installed. They also 
have different software installed. The machine I'm typing this on is a 
quad core processor running at 4Ghz with 16 Gigabytes of ram and a pair 
of SSD's. This thing rips by anybody's standard. It won't run Adobe 
Flash worth a crap. All three browsers will lock up from time to time. 
Kill the Flash plugin and it works but there goes my "multimedia 
experience".

So, it could be hardware, it could be USB driver versions, it could be 
drivers for any of the hardware installed, it could be installed 
software. It could be Windows itself. Point is the Winkey bypasses all 
that stuff and is still "one wire compliant" in that it doesn't connect 
to the radio except the key jack which I assume may already have a 
paddle hooked up.

If you just want to use it for digital modes, 
something like the NUE-PSK might be a good 
solution; I think you'd just have to carry 
batteries and a keyboard that way.

That?s what I have to do right now and its insanely annoying because both the OFF and ON operations are long presses.
One of the great things about the KX3 is that it has outstanding usability from the front panel knobs and controls. The ?adjusting the NR level? problem really kills this.

The Win4K3Suite allows tweaking this via a Spin control that appears to execute the remote commands to change the menu settings. Not an ideal solution because each single level change incurs the round-trip delay to execute the remote commands, making the change from say ?4? to ?7? more time consuming than it needs to be.

Subject: [Elecraft] 10 MHz external reference - GPSDO
Message-ID: <201603140114.u2E1EUUm016697@mail42c28.carrierzone.com>

Guys<

TCXO's use temperature compensating components to try to keep 
frequency stable.  They work fairly well if you are at lower 
frequencies or not multiplying an LO 18 times.  Better is the OCXO 
(which uses a heater inside an insulated "oven" to better keep 
temperature effects isolated).

The EXREF utilizes the better stability of 10-MHz sources to correct 
the drift of the TCXO.  I does that at a fixed interval in between 
which both TCXO-1 and TCXO-3 will drift.  Per Elecraft's 
specifications on page 8 the TCXO-3 is 5 times more stable than the 
TCXO-1.  I have no idea over what time interval the specs are cited, 
but most assuredly its more than 4 seconds.

I cannot compare the TXCO-1 as I only have the TCXO-3.  Both were 
provided long before the EXREF was designed.
I just made a measurement of my K3/10 running 12w for about half a 
minute 28.200.000 displayed at 28.200.001 at the start.  My REF CAL = 
49.380.089 before making the 28-MHz test.  After several minute long 
tests the frequency has not budged off 28.200.001.  REF CAL now is 
49.380.095 so the TCXO-3 has moved +6-Hz over about half an hour.  I 
have been running all afternoon so the K3 was at stable working temp 
before I made a measurement.

Unless you are into frequency measuring or run weak signal modes 
where hearing a signal is quite difficult, being "on frequency" is 
very handy.  If running CW you probably have bandwidth cranked down 
to 100-Hz.  Digital weak-signal modes tolerate even less error.  On 
2m-eme using JT65, drifting more than +/- 20 Hz will result in the 
digital signal failing to decode.

Adding the EXREF improves your K3 by five times so perhaps the TCXO-1 
is satisfactory for your operating modes.
My measurements were really accuracy tests and not stability 
tests.  I did do a 30-minute test at 2m JT65 over a 30-minute period 
where I would transmit one minuted continuous and then receive one 
minute.  MY K3+2m transverter only drifted upward 7-Hz.  It was off 
frequency by 6-Hz at cold start.  K3EXREF with TCXO-3 was used.  The 
transverter uses a heated 116-MHz overtone xtal oscillator inside an 
insulated can.

Does any of this help?
Think I beat this to death - OK?

I think everyone is ignoring something here.  What causes the frequency
drift in the first place?
It is temperature changes - the designation TCXO signifies Temperature
Compensated Xtal Oscillator.  It is already compensated for temperature.
If the temperature of the TCXO stays the same, the frequency should be
stable.

There will be some frequency change during warmup after power on, and
there will be some frequency change during transmit because the
temperature inside the box will increase, and will cool during periods
of receive.
The difference between the TCXO-1 and the TCXO-3 is one of how much.
The TCXO-3 drift will be smaller than the TCXO-1 over the same
temperature change.

The drift over the 4 or 5 second correction from the external reference
will result in a small correction with either TCXO, but it will be
smaller with the TCXO-3.
Additionally, the frequency drift will be quite small even without the
external reference unless there is a rapid and drastic change in
temperature at the case of the TCXO.  These discussions should include
the temperature change during the measurement periods. to complete the
picture.

   Just a heads up, I have just released a new rig controller that
primarily works with the Elecraft KX line KX3, KXPA100 and PX3. If you were
already familiar with Wizkers, this is a Ham-focused version with and
extended KXPA100 monitor.

Wizkers:Radio is a universal Chrome packaged app which runs on pretty much
any computer as long as you can install Chrome on it. An Android version is
also coming up.

Wizkers:Radio supports a lot of unique capabilities such as a graph of most
radio and amplifier parameters, PX3 screenshots, a quick "memory card"
system for each KX3 band as well as support for the PKX3 PSK-D and FSK-D
modes.

And one last thing: Wizkers:Radio is fully open source, head over to
wizkers.io to learn more about the underlying framework!

Awesome! I've been puzzled by the lack of ham radio Chrome apps, and was
toying with the idea of writing something simple, like a clone of DroidPSK.
Wizkers is vastly better than anything I could have written.

Seems like Wizkers would also provide a framework for an cross-platform USB
antenna analyzer; basically this hardware with a Wizkers plugin:

I'd love to replace my RigExpert with a USB dongle that works on Chromebook
or phone. I look forward playing with Wizkers. Thank you for writing it and
open-sourcing it.

Something I have wondered since running MMTTY and looking at the XY 
scope is, why do I see the XY ovals shifting clockwise as the station 
is transmitting. I find decoding is best when the ovals are as close 
to straight vertical & horizontal. If I let them rotate, I lose the 
cypher so I have to actively adjust VFO A to maintain their proper 
spacing.

I always figured that rotational motion was caused by the time being 
shifted as temperatures increase in the TCO ovens and they do resolve 
as the radio cools down, only to experience heat and try and resume 
with the next transmission.

I see this same effect when in transmit albeit not as bad as some do 
on the other end. So my thoughts turn to what mitigates this effect 
on my end and I guess it has to be the TCXO crystals and their 
stability and its with the looser ones causing the greatest motion 
and lack of stability..

I have the higher rated TXCO-3 that supposedly gives basically stable 
transmit down to the occasional rated stability at I believe; to 
.5ppB, a many times better end at the final result.

So I wonder if in the real world, if my assumptions are correct and 
having a decent quality time medium to keep the GPDSO in persistent 
good order will keep the twisting of the TY scope bars more secure in 
place and better that the find the locations for best reading of the 
data?

And further because both rigs are experiencing different temperature 
shifts through the messages creation, it requires a greater stability 
of both top gave that high quality handshake. to stop this rotation 
of the XY coordinates from loosing connection?

I ordered one of the BG7TBL 2015-09-17 Disciplined GPDSO and find it 
uses different chips. These give a 5+ at 10x 000 000 000 800  The 
earlier on the Morion 201 gave a 1+-deviation at the same range. 
miniscule but somethig to consider. I'm hoping if my K3s is attached 
to this GPDSO and the ham at the other end is so configured so that 
neither unit will have grand shifting and a solid - uninterrupted 
signal will be the delightful norm.                                   
        	 	 t
So I'm hoping this strong desire to tame the K3s rock solid will 
result in perfect tight linearity.

I'm looking forward to seeing how well this goes.

50% OT but...

I'm not complaining about stability, mind; the KX3 temperature 
compensation routine works really well, but if I use a GPSDO-clocked 
synthesizer to generate my KX3's clock, will that stabilize the on-board 
synthesizer?  I have a PTS-160.

Many thanks to all who have taken the time to respond to this thread. I 
will continue to try and resolve this issue and as a first step I 
plugged the K3 USB into my Toshiba NB510 Netbook, fired up L32 (slightly 
earlier version) and the CW machine and the software/DTR CW was fine.

The netbook has nowhere near the power of the Dell desktop so 
investigation is in order.

Mike VP8NO

Hi Ed,

Minor note on our TCXO part numbers:

The tighter temp stability TCXO (0.5 ppm typical) is actually Elecraft part 
number "TCXO3-1". This is the p/n that shows on the K3S order page and in the 
K3S kit manual as an upgrade.

The standard TCXO (5 ppm) supplied with the K3S and K3 has the part number 
"E660033".

Regards,

Eric

I agree.  I used twisted pair for a long run up the tower to a pesky

Eric,

Thanks for the correction/update.  That fits my measurements, 
exactly.  I recall about the time the EXREF came out the better spec 
was given on the TCXO03-1.  Regarding the use of wrong part 
terminology (TCXO-3) its just sloppy memory of the exact product 
number.  I think most knew what is being described.  Interesting that 
the TCXO03-1 is ten times better stability over the TCXO.

The EXREF reduces 0.5ppm to 0.1ppm on my K3, which is what was cited, 
I believe.

Subject: [Elecraft] P3 v1.59 & SVGA v1.33 BETA now available for download
Message-ID: <1457979126905-7615189.post@n2.nabble.com>

I'm releasing a follow up BETA since the last release.  Recently we were able
to solve some additional bugs and develop a couple of new features with the
P3 & SVGA that are significant enough to warrant a separate release.  Our
website has also been updated with instructions on how to download and
install BETA release packages. 

Beta firmware and instructions can be found here: 
http://www.elecraft.com/software/P3/elecraft_p3_software.htm


Release notes for P3 1.59 / SVGA 1.33

 MCU 01.59 / 3-7-2016

Version 01.59 requires SVGA firmware 01.33 to support all SVGA features.
(notes marked with *** are those added since the last beta)

* P3 commands in keyboard macros: Added support to allow P3 commands to be
embedded in SVGA keyboard macros.  When entering a keyboard macro using a
USB keyboard attached to the P3/SVGA, P3 commands can now be intermixed with
K3 commands by preceding the with the '#' character.  Example: set up a
macro to set the K3 to PSK31, frequency 14.070, P3 span of 100 kHz, fixed
tune enabled:   
	FA00014070000;MD6;DT3;#SPN001000;#FXT1;

* SVGA keyboard macros as function keys: The first 8 SVGA keyboard macros
can now be executed from the 8 front panel function keys.  First, using a
keyboard, program the macro and make sure to save it into one of the first 8
locations (mem 1 - 8).  Then on the P3, press the MENU button and using the
encoder, select the SVGA menu and press the encoder to enter. Then using the
encoder, choose "Macro 1" through "Macro 8",  then press the function key
(short tap or long hold) to map the macro to the function key. 

* Enable/disable TX sensing at the TxMon coupler: Added TxSensEn to TxMon
sub-menu.  This allows enabling/disabling of transmit sensing at the
coupler.  For K3 and K3S users, TxSensEn can be set to "disabled", which
will use the serial connection from the K3 to determine the TX state.
Setting TxSensEn to "enabled" will use forward power sensed at the TxMon
coupler to determine TX state (useful for non-Elecraft radios). 

*** New #RCF command: "Relative Center Frequency" applies an offset to the
center frequency based on the passed argument.  Usage: #RCFsnnnnnn;  Where:
's' is the sign + or -, nnnnnn is the offset in Hz.  For example, if the P3
is set to a 30 kHz span and you would like to position the cursor on the
left edge: #RCF+015000;   Using #RCF without any arguments returns the
difference in Hz between the center frequency and the vfo frequency. 

* K3S attenuator support:  The P3 now properly scales the display when the
four-step attenuator in the K3S is enabled.

* SWR meter blanked:  Both the analog and digital SWR displays are now
blanked whenever the transmit power is too low to give a valid reading.

* Serial #DSM command:  The Display Mode (#DSM) command now controls the
Transmit Monitor's power/SWR meter display as well as enabling and disabling
the waterfall window.  #DSM0 = Spectrum display only, #DSM1 = Spectrum +
waterfall, #DSM2 = Spectrum + meters, #DSM3 = Spectrum + waterfall + meters.

* New #FON command:  The display font can now be selected via a serial
command.  #FON0 = 5 x 7 pixels, #FON1 = 7 x 11 pixels, #FON2 = 9 x 14
pixels.

* New #XCV command:  The transceiver type can now be selected via a serial
command.  #XCV00 = "K3", #XCV01 = User-defined, #XCV03 = 455 kHz IF, etc. 
The command uses  the same number order as in the "Xcvr Sel" menu item.

* Transceiver definition bug fix - Exiting:  When exiting the "Xcvr Def"
menu page, if the user-defined transceiver is already selected, it will
reflect the new values inmmediately, rather than having to re-select it.

* Transceiver definition bug fix - IF Invert:  The USER transceiver that is
defined in the "Xcvr Def" menu item may now specify "Not inverted" IF tuning
even if the "K3" control language is selected.

* SVGA resolution / main waterfall bug fix:  The main waterfall height had
been switching to the default value after changing SVGA resolution.

* VFO B cursor = VFO DATA A bug:  The VFO B cursor had been matching the VFO
A cursor in DATA A mode, even when VFO B was in a different mode.

*** Bitmap Upload bug:  Fixes a bug in which the waterfall area was omitted
from a bitmap capture when the TXMON meters were visible.  



P3SVGA 01.33 / 3-7-2016

* Center Frequency in Tracking mode:  Fixed an old bug that caused the VFO A
cursor to reset to center of screen when VFO A was tuned after the user had
adjusted the center frequency offset using the CENTER function in tracking
mode.  

* SVGA Keyboard: 
	Added support to allow P3 commands to be embedded in SVGA keyboard 	macros.  
	Added support so P3 can execute keyboard macros from front panel function
keys. 
	Keyboard / USB thumbdrive can be used when not in data display mode. 		
	Cleaned up the text message sending, and use of the IM character '|' for
better 	handling of short text messages.  

*** Scratchpad:  Removed "replay buffer" and replaced it with a scratchpad
memory.  To use the Scratchpad memory, press the Insert key.  A one line
window will pop up and allow text to be entered.  Press Enter, Esc or Insert
to exit the scratchpad.  Scratchpad text can be sent by pressing
Ctrl-Insert, or embedded in a text message using \s .  You can also exit 
the scratchpad by pressing a predefined text message key.  This is handy for
inserting a call sign into a preformatted message. 

Example: create a text message that contains:  "\s de wa6hhq ur 5nn k" and
assign it to the F5 key.  Now to quickly respond to a calling station, press
Insert, then enter the call sign of the station, for example N6KR and then
press F5.   The call sign entered in the scratchpad will be entered into the
message and transmitted. 

***Message counter adjustable field width:  Message counter now takes an
optional precision value that controls how many digits are converted.  The
existing operation of  \c  in a text message would print the message counter
using all 5 digits.  Now \c can be followed by a number from 1 to 9 which
sets 	the minimum number of digits displayed.  
For example, if the current contents of the message counter is 27,  \c2 
would display 27,  while \c4 would display  0027. 

*** Multiple \c in a text message does not increment the counter:  In the
past each time the 	\c was used, the message counter would increment. This
has been fixed so that the message counter only increments after the message
is completed.

The XY RTTY tuning ovals are based on the mark and space signals 
which are 170 Hz apart. I can easily tune RTTY signals with the 
10 Hz tuning step in the K3, so 10 Hz stability on both the 
transmitter and the receiver should be good enough for reliable operation.

With the low stability TCXO and no external reference, I get 
good results with RTTY. I don't notice shifts in the ovals.

Paul,

Thank you and everyone involved for the additional features! ?I did not
know about the counter increment... ?Time to build more macros...

The Center offset has been so useful! ?I hit a button, and the DX moves
to the left edge, and I see the pileup on the right... ?

I have had a bit of a chance to test this over the past few weeks, and
it makes a huge difference in speed of nailing a station.

During the Wisconsin QSO Party this weekend I experienced on a few occasions were a strong signal was near zero beat (maybe +/-50Hz or better), but all I could hear was "thumping" of the signal. ?So these people were calling me, but I could not hear the 600Hz sidetone. ?In order for me to hear them, I enabled RIT and tuned a few hundred hertz up. ?I could see them in the passband of panadapter.
- Issue was with about 5 strong signals- Filter centered and 200-400Hz wide- Signal was visible near zero beat on NaP3 panadapter within pass band. ?I/Q input to PC for visual spectrum only. ?Not using audio from PC.- Preamp off in many/all cases on 40 meters.- Listening to audio via stereo headphones direct to radio.- Firmware updated last fall.
Any ideas or known issues in this scenario?

Portable I think is the key word.  I use the following little windows tablet:

http://www.microcenter.com/product/439773/TW700_Tablet_-_Black <http://www.microcenter.com/product/439773/TW700_Tablet_-_Black>
I always buy the open box ones $52 (I?ve bought several for friends who don?t live near a MircoCenter.)

They require an external USB dongle and I recommend an external travel mouse.  You should be able to get both for a few dollars.
Also the onboard storage is small, so uninstall office 360, their virus software, and stick an external SD chip where you install all additional software packages to.

It?s a super little performer, extremely compact, energy efficient (charges over a 5W USB cable) it light and surprisingly durable.  
I take mine on travel and hiking trips.  It runs fldigi, RMS express & FSQCall flawlessly.

Cheers!

Hi All,
I thought some of you might like to hear about my little exploit.
It concerns my KPA500 going deaf. I know a lot has been said here about
it and how to fix it. Well mine seemed to develop a deafness on rx in
OPER mode. When it happened I noticed that there was an asterix on the
display and couldn't understand why.

The story is that on one of my antenna ports from the ATU I have several
Antennas which get switched in by relays driven from a home made box
that decodes the band info from the K3. This weekend I put up another
antenna and did away with all the switching but left the control box
connected and switched on. However when I switched it off the RX stayed
ok until the amp went into TX and wouldn't go back to rx. The asterix
stayed on. It seems the power drain on the data lines etc was sufficient
to drag them low and prevent the "PTT" going back high. Removal of the
controller or re powering it solved the problem.

The problem was self inflicted but I did solve it quickly but thought
the story maybe of help to some one else who does the same silly thing.

Charlie:

I have had good success with the Lenovo Yoga 2 11 ($400).  It's actually my
wife's machine, but I use it when we travel to places.  

It's not the fastest machine, and the screen is not the biggest, but its
small, light, flat, easy to use, quiet and runs everything I need to connect
to both a K3 and a TS590.  I use a Microham Microkeyer 1 when taking my
radio on the road.  Used with care, you can get around 3-4 hours on the
standard battery, and bigger batteries are also available on Amazon. I've
not needed these since there is power where I have taken this setup.

The two biggest detriments for this machine is that it has only two USB
ports.  But the easy fix is a 7 port powered USB expander, which fixed that
issue and add little weight to the package. The other detriment is the nutty
on board touchpad, but a $5 Wireless Mouse fixes that just fine

I don't use the touch screen at all.  The keyboard, as in all ThinkPad
computers, is superb for touch typing.

Your SSB bandwidth (passband) is prob 2.7 kHz and your CW passband might be 400. You not only have to consider the side and but your side tone offset and bandwidth. 

There is a setting in the CONFIG menu to make this work however.

Bob,

Assuming you have the CW signal (in SSB mode) tuned to your sidetone 
pitch ---
You will have to re-tune by the amount of your sidetone pitch when 
switching to CW.

The K3 (and all other Elecraft transceivers) insert a VFO offset between 
SSB and CW equal to the sidetone pitch set into the radio during receive.
SSB has no offset.

In other words, if you are listening to a 600 Hz CW signal when tuned to 
a 7040.00 kHz CW signal when in SSB mode (and your sidetone pitch is set 
at 600 Hz), you are actually hearing a CW signal at 7039.40 kHz when 
tuned to 7040.00 kHz (assuming you have LSB set in SSB mode).
When you switch to CW, you will have to tune to 7039.40 kHz to hear that 
same CW signal at 600 Hz - and that is the actual CW transmit frequency.

In other words, in SSB mode, the K2 frequency indication is the 
suppressed carrier frequency, but in CW mode it is the transmit 
frequency of the CW signal.

To further complicate matters, if you set CW in SSB on in the menu, that 
relationship changes.  You will transmit offset from the suppressed 
carrier frequency by the amount of the sidetone pitch so your signal can 
be heard by other stations tuned for SSB.

Don W3FPR

Message-ID: <56E7692C.8030702@storm.ca>

There are two parts to this: the correct sideband, and the correct 
frequency. On the K3/K3S, CW is on lower sideband, and CW-REV is on 
upper sideband. On bands where you use LSB for SSB, switching to CW will 
still be on the correct sideband, but on bands where you use USB for 
SSB, you will need to use CW-REV to get the sideband to match.

The other part is the frequency offset. You can tell the K3/K3S to do 
the frequency offset automatically when changing modes by using the 
CONFIG:CW WGHT menu item and tapping the 5 (AGC) button until the lower 
(VFO B) display reads VFO OFS.

Don,

The K3/K3S will automatically handle the offset if you configure it
to do so.  From the K3 Owner's Manual, page 29:

To answer the original question - with CW WGTH 5 set to VFO OFS I have
no problem tuning a station in SSB and switching to CW without losing
the signal.  The station is  it more "accurate" on 160/80/40 where one
switches from LSB to CW-L than on on 20-6 when switching from USB to
CW-L but it's still relatively close (as accurate as I can match the
correct CW pitch when tuning in SSB).

I recently purchased a new K3s and no longer have use for my 
old K3 friend #202. Of course, it is not pristine having 
been opened up and put back together many times over the 
last 9 year, but it is fully functional to original specs 
and has been well maintained over the years with all known 
official mods and updates applicable to this serial number. 
Additionally, it has the new and improved synthesizer 
board(KSYN3A) and Interface module (KXV3B) installed (Same 
as in new K3s). Upon request, I will provide a listing of 
all mods and updates accomplished. I am the original owner 
and radio has always been in a non-smoking environment.

This is a K3/100 with the following options/updates installed.

K3/100     s/n 202
KPA3        100 watt Internal PA
KAT3          Auto Tuner unit
KSYN3A    New Synthesizer board. Same as is in the K3s ($220)
KXV3B      New with 2 level preamp for 6, 10, & 12 meters. 
Same as in the K3s ($200)
Standard 5 pole 2.7 kHz crystal filter

All manuals, documentation, update details, power cord, hex 
wrenches, and RF board jumper block included.

A new similarly equipped K3 sells for about $3200 plus s/h. 
Asking $2295 shipped UPS ground to CONUS. Will accept 
PayPal, USPS Money Order or bank draft.

Message-ID: <CALQT3yw93h-jT0T97zBF7DyXe4gYmYe8YzRdkJJqQBcj5g4gdg@mail.gmail.com>

Hi folks,

For 40m, 30m, and 20m, the KX1 docs recommend a ~24' length of
sorta-vertical #24 wire with shorter counterpoises as a good field antenna.
I've set that up for my KX1 and KX3, and (unsurprisingly) it works well on
both.

For 80m, the KX1 docs recommend a resonant antenna, and I'm considering my
options. Most of what's written out there about low band antennas seems to
be about durable (and heavy) mobile or home installations. Does anyone have
any experience they'd like to share with backpackable lower band antennas?

Options and questions I'm considering include:

* Build a coil big enough to load up my 24' vertical on 80m, with a tap for
60m. Will that be a long enough radiator?

* Figure out the kite-vertical thing, fly a wire close enough to l/4 that
the KX1 can tune it. How bulky would that be?

* Will #24 wire be a decent radiator for the lower bands, or should I eat
the (not-inconsiderable) weight of a bigger gauge?

* Does anyone have any tips on constructing backpackable (minimum weight)
coils? What's the smallest wire and lightest insulator?

* I'm planning a vertical, as this would seem to require strictly less wire
and coils than any dipole or inverted vee, but am I missing some other
offsetting advantage?

Cheers,
Bruce

I've had good luck with antennas made from RS 22 AWG Speaker wire and an Elecraft BL-2 BALUN. A 100 ft spool will yield a 135' doublet with about 30+ feet of "twinlead" feed line. You can make insulators from pieces of plastic toothbrush handles. Add a kite wonder from BuddiPole or other QRP sites and all you need is a tree for a Inverted V.  It's also neat to make it an OCF by taking about 20' off one end and splicing it to the other end. Then when you put the center over a tree, the feed point is to one side.

Hi Bruce,

Have you thought about using a 9:1 unun and about 100 ft of wire with a 
short counterpoise?  The unun -may- get the feed point Z down into the 
range where the KX1 tuner can match it.  I picked 100 ft because it's 
not a quarter wave or half wave on either 80 or 60 plus and it's more 
than a quarter wave on 80.  You could go to 50 ft but it would be less 
efficient on 80 meters.

An alternative to the unun would be to use a matching network consisting 
of a link coupled tuned tank circuit.  Tap the resonant coil to get both 
80 and 60 and tap the link every turn for 6 - 8 turns to get close to 50 
ohms.  Wind the coils on a small (~1.5 inch) powered iron toroid and use 
a small BC band variable cap.  For under 20 watts the components would 
be light weight and fit in a small plastic box.

Have fun!

Brian, K0DTJ

Greetings all.

We are considering moving to a location that is more friendly to ham radio
and especially the performance of my K3.  Here in our crowded neighborhood,
I have regular S7 noise levels on all the lower HF bands.  One home we
found (and like) sits fairly close to high tension wires (ie like one lot
away) however its in a much more rural area and likely to be more quite
w.r.t. the usual man-made RF hash.

Does anyone have any experience with living very close to high tension
wires (not tool close, plenty of room for wire antennas without any
danger.)  Assuming nothing is "broken" is it likely to produce RF noise in
the receiver?  Is this something I should be concerned about?

Hi Chris!

It sounds like you're speaking of a distribution line.  Do you have
any idea that the voltage is?  Is there more than one pole at each
cross arm?  It could be almost anything up to 240 KV ... or more.
In my semi-rural area the voltage for distribution is 14.4 KV, which
is pretty usual these days.

Do you have any contact with other hams in the area?  If so, what
are their experiences with noise and dealing with the local power
company?  Some companies are very good about dealing with
noise matters ...others are abysmal.  Odds are that there are hams
working for the power company's communications department if they
do their own maintenance work.  You might call your Public Service
Commission and ask if they have any observations.

Drive around the prospective neighborhood with your can radio tuned
to the very top end of the BC band and see what you hear.

I'm a retired power company communications technician and one of
my jobs was to travel the state (Montana) as the line noise technician,
so I feel like I'm qualified to comment.

73!

I've always been a fan of end-fed half wave wires for portable 
operation, as they don't require a ground system, nor do they require a 
balun or feedline.  The inverted L configuration works well, as the high 
current point is a quarter wave from the fed end.  Make that as high as 
you can.  The horizontal part of the wire radiates much like a dipole.  
It will also work, perhaps not quite as effectively, simply sloping up 
from the feedpoint.  Note that this is antenna NOT the same as the usual 
quarter wave inverted L, which has maximum current at the feedpoint, and 
works more like a vertical.

The downside is that the feedpoint impedance is very high, perhaps 2,000 
Ohms, which may be beyond the range of the KX1 tuner.  It is, however, 
very easy to build an L network to match it.  (I can provide L and C 
values.)   I'd also attach a couple short wires to the radio ground to 
act as a counterpoise, though it may not make much difference.  A couple 
6 foot wires should work for 80 and above.

This kind of antenna will work on any band for which it is a multiple of 
a half wavelength, though the radiation pattern will be like a long wire 
at higher frequencies.  On 10 and 15 meters, if you can get a half 
wavelength wire nearly vertical, it will act like a half wave vertical, 
which may be better for low radiation angles.  I used one of those a few 
years ago in the 10 Meter contest from KP2 and, in spite of a terrible 
location, a bunch of people heard me.

73,

Message-ID: <56E87007.1020704@horizon.co.fk>

G'day all,

Time to put this saga to bed.

Further investigation revealed that my Toshiba Netbook with a slightly 
earlier version of Logger32 (3.50.231) ran software CW (DTR keying) over 
the KIO3B USB port without issue. The main PC was running version 
5.50.252. I transplanted the Tosh version on the main PC and indeed that 
too ran perfectly OK. So what had changed between versions?

Eventually it was suggested that I should check in the CW machine config 
to see if "disable radio polling when keying" was checked. It wasn't so 
I did and that resolved the problem.

Curiously in the Tosh version 3.50.231 it wasn't checked but that ran OK 
on both the Tosh and the Dell so there is still something in play, 
however, the ripples in space time have been smoothed and I am back with 
a fully functional one cable solution for CAT/PTT/CW/Audio.

Many thanks to all who took an interest in this problem and all those 
who were fearful can rest easy. That is not to say your time won't come.

Mode? Is the TX light flashing? Which antenna is selected? Is SWR indicated?
Does the RED led light when you key down?

Try Cw MODE, ANT1, if you have the ATU installed bypass it for testing..

Others might be interested ...

We moved here to Sparks NV last Aug.  Prior, we lived on 5 rural ac 
outside of Auburn CA for 38 years.  Distribution lines were 12 KV, we 
had our own pole pig.  There was a 69 KV tie line on wood poles between 
two hydro plants that cut across the south corner.  There was 
two-circuit 112 KV line on metal towers about 1/4 mi to the east that 
had a tap across the south end of the property again about 1/4 mi. 
Never got any noise attributable to any of them.

Now, the CalTrans sodium vapor street lamp at the Interstate off-ramp a 
mile away was a whole different story.  It began to fail about 4 years 
ago, and I never could get them to replace the lamp and ballast.  Over 
the years, the ambient noise rose slowly, almost all from the ubiquitous 
SMPS, most probably ours and our nearest neighbor.

Growing up [a long time ago], a two circuit 230 KV line from Hoover Dam 
to Los Angeles ran a block away.  Never any noise from them.  We drove 
through the little town a couple of years ago, it is now a 500 KV line 
and no noise on my mobile driving on the road right beside it.  My 
experience is that the HV lines [60 KV and up] get good maintenance and 
are almost universally quiet.  Distribution lines not so much.

Count the "fins" on the insulators to estimate the voltage.  69-70 KV 
are often on large umbrella type or short hanging ones.  The 112 KV were 
hanging from ones with about 6 sections.  230 KV usually have 12-14 
sections.  500 KV [and DC interties] have too many to count.

I agree. Here's an easy way that I developed to feed one. It's an 
adaptation of one that N6LF showed on his website.

I have a high voltage distribution line running along my property line 
that has not been a problem in the 10 years I've lived here, but there's 
been other power line noise around that's radiated from other poles.

The antenna efficiency drops very quickly when the radiator is made shorter
than 1/4 wavelength or 66' on 80 meters. When end fed the efficiency of a
short radiator is even lower depending upon the "ground" return system. The
RF power is divided between the radiator impedance and the "ground"
impedance, with the most power going to the higher impedance. With a short
radiator such as a 24 foot wire, the radiator may show something in the
order of 10 ohms while a typical "ground" will be in the range of 300 ohms
or more, so less than 5% of the RF power actually goes to the radiator.
Short (<1/4 wave) "counterpoises" may actually show impedances up to 600
ohms or more, halving again the RF power going to the antenna. 

Note that many Hams have used such systems - a short whip on their back
dragging a single wire on the ground behind hem for pedestrian mobile - with
considerable success. That just demonstrates how little radiated power is
required under some conditions to make good contacts. So what you
contemplate will certainly work to some extent. 

I have found that the best way to load an electrically short radiator is to
do so at the center. You can think of it as a short radiator and an equal
length counterpoise both up in the clear. Use parallel spaced feeders to
avoid the inherent losses in low-impedance coaxial line. Your tuner will
need to be able to efficiently match quite low impedances in many
situations. The Elecraft tuners use L-networks which are quite efficient
under those conditions, as long as they can find a matching combination of L
and C.

Whether it's a stack of full size yagi's on a 90-foot tower or a short wire
thrown into a tree, the compromises are always the same. It's a matter of
doing what you can within the constraints of space, cost and time. The
suggestions offered by Wayne in the Owner's Manuals are what he has found
will work with the ATU with a minimum of effort. Because of space
constraints inside the KX1 its ATU matching ranges are more limited than the
KX3 or other Elecraft rigs.

The 6 meter moonbouncer who lives up the hill from me told me he has no 
problem from the high-tension line that runs right by his place but has 
experienced noise from the lower-voltage lines farther down the hill.

I suspect that HT lines are probably less likely to have arcing than 
lower-voltage lines, simply because it would be a much bigger problem 
for the power company if they did.

Drawing from a decade of experience working as head of the PR department for a major electric utility (a long time ago), I?d like to suggest that arcing per se should not be a problem at any time with any power line if it is functioning properly. The individual transmission wires are spaced far enough apart that arcing shouldn?t be possible. Many utilities regularly wash down the insulators of high voltage transmission lines using specialized equipment that cleans condensed salt water fog off the insulators with deionized water (necessary to keep from zapping the guy running the spray nozzle). This is to prevent arcing between phases, which can otherwise occur in high humidity situations.  If there?s noise coming from lower-voltage distribution lines down ?down the hill? I would name the prime suspect as cable TV equipment that?s hung on the same utility poles as the power line. If the RF interference is caused by power line arcing, it?s going to get detected and fixed pretty quickly by the utility. If it?s there all the time, it very likely isn?t the power company at fault. (This discussion doesn?t include any consideration of Power Line Communication technologies, which are an identifiably different kind of interference.)

Message-ID: <201603152359.u2FNxWw0005819@mail42c28.carrierzone.com>

"Time out" for interesting event that happened a few minutes, 
ago.  My wife commented that something "HIT" my tower, as she heard a 
"bang" and noted the guy line that secures to post on the front side 
of the house was moving very "agitated".

So in my slippers I went out on the back deck for a quick 
look.  Tower and antennas all looked fine.  Walked to the end of the 
house where the tower is mounted and secured with wall bracket at ten 
feet.  All fine --- oh there is a guy line draped down where it 
should not.  Further inspection showed the guy to the back side of 
the house had broken.  I walked to the guy post and found that the 
turnbuckle end that secured the guy wire had bent full open and tip 
broken off.  Guy post laid over almost horizontal in direction right 
angle to normal guy force.

We didn't see it but only thing big enough to exert enough force to 
break the turnbuckle would probably be a Moose.  The end hook was 
totally straightened out so the guy loop just slipped off.  Hook on 
other end of turnbuckle looks fine; 3/16 inch galv guy wire survived.

We have been experiencing daily winds above 20mph so that might have 
fatigued the end-bolt hook.  Last two days totally calm, 
though???  --- Then "BANG!"

OK, back to Elecraft "stuff" ;-)

Lew,

That's in direct conflict with everything I've seen from RFI engineers. 
Over the years, I've seen plenty of reports of hardware in the power 
system failing in a mode that causes it to arc. See 
http://www.arrl.org/power-line-noise for a great discussion of all sorts 
of RF noise, including power line noise. At least 10 years ago, I bought 
and read "AC Power Interference Handbook" by Marv Loftness, a field 
engineer who specialized in that work. He said that virtually all power 
line noise is caused by SOMETHING arcing.

The Loftness book is the "go to" text on power line noise.

EVERY metal-to-metal junction is suspect.  Lazy linemen hammer lag bolts
straight in when installing cross arm braces.  Metal steeples holding
ground wire running down a pole arc and set poles on fire.  The list is
endless.

Please reread the first sentence of my prior post, in which I qualified what I said with the phrase ??if it?s functioning properly.? What I said is NOT in conflict with your points. Power line noise is, de facto, the result of some sort of equipment failure. We agree on that. If something is arcing in a power distribution system, it?s because something is broken.

I suggest that we take go offline with any further discussion on the issue, since it is OT.

The arcing that causes RFI is usually not from the power lines 
themselves, but various pieces of poorly bonded hardware NEAR the power 
lines.

Here in Northern California where PG&E is our power utility, it is 
usually possible to get them to send a crew out to investigate and 
document an issue, but nearly impossible to get it fixed. NI6T, an EE 
with considerable experience in the matter, managed to get cozy with at 
least one PG&E investigator, and learned that managers of the department 
that FIXES these problems is rewarded in proportion to their annual 
budget that is NOT spent. In other words, they are incentivized to NOT 
fix problems.

Another local ham who is an attorney found that contacting the state 
agency regulating PGE got his problems fixed when PG&E had previously 
failed to do so.

Since the experience of both of these hams is directly related to 
business practices and the profit motive, one might reasonably suspect 
that they are at least somewhat universal throughout the industry.

Thanks, folks, this has been very helpful. In particular, Steve's "wire
lengths to avoid" calculator will save me a bunch of time. I've purchased a
kite and a bunch more wire, and we'll see how this goes.

Well said, Dave.  Unlike another poster, you appear to have an excellent,
first-hand knowledge of the problem.  My 18 years as the line noise tech
with the Montana Power Company validates your observations.

Message-ID: <56E9A32C.7070609@digis.net>

I have a Logitech K400 keyboard wireless adapter plugged into my PX3. 
The keyboard transmits to the PX3 screen. Tapping Control T and the CW 
message transmits, you can hear it on the KX3 CW monitor. The power is 
set to 5 watts so the rig is not in practice mode. The problem is the 
KX3's red LED does not show transmitting, and there is no power out, but 
the message does play. Looked through the menus for some type of TX 
keying recognized from the keyboard but found nothing. Anyone with 
keyboard experience. The PX3 and KX3 have the newest software upgrades.  
Just hit me, I did not try the VOX. Thank you, WA7NDD

Actually, there have been some problems from those high voltage lines. I 
believe these are on the order of 300kV. Official word from PG&E is that 
they will not make any repairs solely for RFI because it's too expensive 
to do it.

You should copy this to the RFI mail list, so the ARRL folks are made
aware that has become policy for a power company...

It supports 1440 x 900 resolution, which is best for the P3, as

Adorama is a respected retailer.

Good day,



I am programming Macros for my KX3.  Recent issues have relegated me
back to just my trusty KX3 for all things HF.  When in the shack, I
usually operate low power digital modes and have my macro nearly
perfect.  The one parameter I cannot get right is to switch ESSB so I
am able to TX in the upper part of the JT area and use JT9-ESSB works
great for this!  As you can see below, I am trying to use the MN096
and a toggle (MP00) to set the bit to on, but it does not work.  I am
certain it is just a syntax error.  Also, for when I am doing voice
and SOTA, I would like the command to do the opposite and turn off
ESSB.



Digital Macro:

TE-00-00-00-00+00+00+00+00;PA0;MG001;AG004;BW0400;IS

Dear all,
I've started to play around with my KX3 in a SO2V configuration under DXLOG.
Is there a way to control the Sub-RX AF independent of the Main-RX AF? Until
now I haven't found the corresponding front panal control.

Right. But most engineers would view the lines and that hardware as a 
"power distribution system," and an attempt to separate the two a game 
of semantics. A chain is only as strong as its weakest link. :)

Yes, and buried in there is the reason why it is so hard to get the 
power company's attention for distribution line noise [12-14 KV] ... the 
loss to them is minuscule compared to other costs.

With no disparagement of power linemen intended, distribution is almost 
universally on wood poles if it isn't underground.  They're assembled 
on-site to more or less standard configurations, and the hardware often 
reclines in the back of their trucks exposed to the weather and 
oxidation for weeks [or months].  The standard configurations usually 
require some [or a lot] of on-site "special engineering" to satisfy the 
real-time need at a given pole.

Above distribution voltages the lines are engineered.  Towers are built 
to fairly exacting standards and erected by professional riggers.  If 
something is wrong, they go back to the engineers.  The power company 
*does* have an interest in corona and leakage losses at 100 KV and 
above.  I think that's why most really high voltage lines are quiet.

RFI from distribution circuits is really an FCC [or other national comm 
regulator] responsibility ... they're incidental radiators under Part 15 
in the US.  That said, the K3 NB took out almost all the distribution 
line noise I had when we were in CA ... it failed on the CalTrans street 
lamp, but so did everything else. :-)  I rarely used NR, just couldn't 
find the sweet spot to make it effective.

I have a 300KV distribution line about 0.5 miles from my QTH, and have not had any significant issues. About every month or two I walk along two miles of the power line with my KX3 checking for increased noise on various bands that I normally use. Only once in eight years did I hear anything and it was only about 3 to 4dB above my normal noise levels. A week later I checked and didn?t hear it. Could have been the power line or could have been something else.

connected to my SteppIR beam on 15, and I hooked up my KX3 to an EFHW wire 
which is about 100 ft away from my SteppIR. 
With both the Flex and the KX3 in receive mode on 15 meters, I noticed on the Panafall
display of my Flex rig, that my KX3 is transmitting a birdie about 700 Hz below it?s RX frequency. 
When I turn the dial on the KX3 I can see it moving up and down the band on my Flex radio. It is quite
strong, about 70 dBm.

Is this normal ? for the KX3 to put out a ?birdie? 700 hertz below it?s displayed RX frequency ?

Thanks - yes, when I disconnected the EFHW wire antenna going to the KX3, then the birdie
that I could hear on my Flex radio disappeared. So it?s getting out through the antenna that
the KX3 is using

Yes, that's the LO leaking out the antenna jack of the KX3. Set a menu function to RX ISO or some such.

Hi John,

That is normal, as the KX3 is a direct conversion receiver and the LO can radiate through the antenna, however to reduce this Elecraft have put in an isolation preamp which you can enable and should reduce the level of this. Try changing  RX ISO to ON in the KX3 menu.

Yes, The DEV reflector is definitely not working correctly.  My ISP strongly 
denys that they are filtering traffic from there.
I have only received ONE email from the list since yesterday.

The problem is the KX3's red LED does not show transmitting, and there is no power out, but the message does play. Looked through the menus for some type of TX keying recognized from the keyboard but found nothing. Anyone with keyboard experience. The PX3 and KX3 have the newest software upgrades.

And then, you are on a ship in mid-ocean with the headphones on, it's
sometime in the 1990's or before, and you are copying a message in CW on
your mill (typewriter) when a lightning bolt blasts the mast next. 

There was a reason radio officers wore their headphones on their heads with
the earpieces in front of their ears, never directly over them.

Subject: [Elecraft] K3 RTTY Decode
Message-ID: <CABD27UkgTnNH6nvanJG9Fz=jEsHm8NAFyy3tkPR2zAOTvNO_3A@mail.gmail.com>

Good friend K1GQ wondered out loud about real data comparing K3 RTTY decode
to software decoders. Here is fifteen minutes of real data.

Attachment 1. K3 decode captured by K3 Utility program. K3 width 400 Hz.
Didn't fiddle with K3 decode parameters--used factory defaults.

Attachment 2. MMTTY decode. AA6YQ FIR512 profile for first five minutes,
them Fluttered Signals (FIR) profile for last ten minutes.

If attachments didn't make it to list, email me and I will send them to
you.

Data captured during first fifteen minutes of 18 March zulu NCCC RTTY
Sprint.

Used MMTTY cross bars to tune.

The sometimes frantic NS is a good test with lots of frequency changes,
great signal-strength variability, and QRM.

My take is that MMTTY is superior to K3 decode, but I was pleasantly
surprised by how well K3 decode performed.

My work is done. I'll leave it to others to draw more rigorous conclusions.

Regardless of relatively decode performance of K3 versus MMTTY, I believe
the most important plus of MMTTY and similar programs is call and exchange
parsing, highlighting, and clicking into log window.

When contesting, I have one MMTTY window and two 2Tone windows open and I
constantly scan all three. My experience is that sometimes MMTTY is better,
sometimes 2Tone Flutter is better, and sometimes 2Tone Selective is better.
I often end up integrating bits and pieces from all three windows to
complete a contact. That's part of what makes RTTY contesting fun. Your
print may vary.

Diddle Exuberantly,

Hank, W6SX

Subject: [Elecraft] FS: K3/100 w/Options
Message-ID: <56EBDFAF.6090707@cox.net>

I recently purchased a new K3s and no longer have use for my 
old K3 friend #202. Of course, it is not pristine having 
been opened up and put back together many times over the 
last 9 year, but it is in great shape and fully functional 
to original specs and has been well maintained over the 
years with all known official mods and updates applicable to 
this serial number. Additionally, it has the new and 
improved synthesizer board(KSYN3A) and Interface module 
(KXV3B) installed (Same as in new K3s). Upon request, I will 
provide a listing of all mods and updates accomplished. I am 
the original owner and radio has always been in a 
non-smoking environment.

This is a K3/100 with the following options/updates installed.

K3/100     s/n 202
KPA3        100 watt Internal PA
KAT3          Auto Tuner unit
KSYN3A    New Synthesizer board. Same as is in the K3s ($220)
KXV3B      New with 2 level preamp for 6, 10, & 12 meters. 
Same as in the K3s ($200)
Standard 5 pole 2.7 kHz crystal filter

All manuals, documentation, update details, power cord, hex 
wrenches, and RF board jumper block included.

A new similarly equipped K3 sells for about $3200 plus s/h. 
Asking $2295 shipped UPS ground to CONUS. Will accept 
PayPal, USPS Money Order or bank draft.

Please reply off-reflector to <kenk3iu at cox.net>

If it's like my K3 and K3s, you might just be tuned outside of the band
somewhere in the 17m "memory". Try going to 15 meters and just tuning down
manually to 18mhz. Then see if it appears when you toggle through the band
changes...
Just a thought,

Jim,

Do a Direct Frequency Entry for 18100 kHz and it should come back.

Subject: [Elecraft] Macro to adjust THR
Message-ID: <1458317250088-7615287.post@n2.nabble.com>

I usually set the THR on CW decode to about 3 for reliable copy. I would like
to create macros to change it to 3 and 4 and also auto. 

Can some one help me figure these out? 

Oh and by the way the new P3 beta is awesome. Thanks

I use the decode as a backup to myself I guess I have not learned to have
confidence in my decode. Plus during dx or contest people fly with code, so
I need help there. 

Thanks again.

Interesting - not working on Win 7 machines or the Win 10 machines. 
Maybe Time Warner views the list as vermin and has it blocked. All else 
is working here and it is not a cache problem either. Not the first time 
this has happened - it takes care of itself after a few days. Maybe it 
will this time also. I even dumped the router/modem - no joy there, just 
wasted time.

Together with my K3 I ordered a KUSB back in 2008 (?) but never used it.
Today I opened the package. The instruction sheet is Revision A, dated
October 8, 2007. The enclosed mini-CD was unreadable, so I plugged the KUSB
into my Windows 10 PC and wondered what would happen. A driver was found but
the entry in Device Manager showed the famous yellow triangle plus an error
messge "The device cannot start (Code 10)".

After reading this and other threads in the Elecraft reflector I didn't want
to give up, but quickly found this solution:

Works great! No need to throw away your old Prolific PL2303 device!

Subject: [Elecraft] K3s BG7TBL 10 MHz reference with K3EXREF
Message-ID: <56EC5B2E.15091.AB2600C@Gary.ka1j.com>

Today was a pleasant surprise, the BG7TBL GPS Disciplined Oscillator, 
external reference arrived and much faster than I expected China Post 
to provide. There is no software or tech manual that comes with it so 
I didn't know what to expect. There are 3 LEDs an ALM, GPS Lock & 
Run. No idea what to expect with these & a web search did not lead me 
to a manual. 

This one is listed with the 2015-09-17 date (Version) stamped on the 
front. Ebay # 331800738725 - It contained the GPSDO, antenna and 12V 
wall wart. The GPS is a U-blox NEO-6M-0-001 and the OXCO is a 
Oscilloquartz 8663-XS dual oven. Reading the stats on the stability, 
it's pretty amazing, search down for the 8663:

http://tinyurl.com/h4j58ea

There's some interesting and lengthy discussion about this series of 
GPSDO on the eevblog site. Interestingly, the OXCO in this version of 
the unit is different than listed on the master reference on the 
first page:

http://www.eevblog.com/forum/testgear/bg7tbl-gpsdo-master-reference/

I did find the ALM LED remained on for 20 minutes or so and with a 
GPS lock (maybe one minute) the LED came on and remains on. The Run 
LED flashes around 3 times/second. Not sure what the flashing 
represents.

I attached it to the K3EXREF and followed the directions to enable it 
in REF-CAL, in configuration. The effect wasn't immediately obvious 
but when I went to copy RTTY there was an apparent improvement to the 
copy in MMTTY and after transmitting, it seems like the recovery to 
copy is much faster than before. I'm looking forward to trying some 
of the digital modes and am happy this reference is engaged and the 
stability will be kept to the minimum needed.

One thing I am wondering is how often the K3s utilizes the 10 KHz 
info being provided. I think I read every 4 seconds or so but I'm not 
sure I have that right. Nifty little piece of equipment to work with 
the K3/K3s

Hope some find this info useful.

73,

Gary

Bad advice.. prolific devices are terrible when data overruns happen and not
just for ham, but for gamers and labs too.

This is another klugde to make these crappy drivers work under windows 10.

Get an FTDI or SILabs chipset..  much more stable

Never had a problem with Prolific parts - except for the end-of-life
variants (HXA & XA)  they removed from driver newer than v3.2.  FTDI did the
same thing for a pirated USB part. 

Here is the solution, without the actual v3.2 driver.  Seems Prolific
doesn't want that made available.  Go figure.

Works great! No need to throw away your old Prolific PL2303 device!

Message-ID: <1458334709321-7615300.post@n2.nabble.com>

I know that we can retain the operating mode in VFO A and VFO B and the radio
returns to the last operating mode in each VFO. Great. Is there a way also
to retain the power levels for VFOs? It would be convenient when moving from
SSB in VFO A at QRO levels to go to VFO B for instance at 40 watts for PSK.
Now one manually changes the power levels when changing VFOs. Now, each VFO
uses the last power level set for either VFO, requiring an adjustment for
QRP, digital and SSB. Just a thought for a helpful future upgrade if
possible. Ron KM4VX

Subject: [Elecraft] KAT2
Message-ID: <CADENs2-QJUugmufMF3r+BesBB8KOyX31YwhKbVrWm1qGUypeQg@mail.gmail.com>

I recently installed the KAT2 in my K2. Using a 20 meter inverted V dipole,
it was working great with no problems. Then I tried it out on a end fed
antenna and it also tuned it up. Then I switched back to my Inverted V and
every time I try to tune it up I get LO P on the display. I looked it up
and this means Low Power, so I increased the power to 15 watts and I still
get the same message. I can't increase the power any more. Does anyone know
what is happening?
Thank you

Aaron,

The KAT2 needs only 2 watts to TUNE - in fact the firmware limits the 
power to 2 watts during a TUNE.
What was the SWR reported when you tried to tune the end-fed antenna?  
My guess is that the SWR was high.
The most common cause of LO P message is that the K2 PA cannot deliver 2 
watts - and that may mean one of 2 things - the PA transistors have been 
damaged, or the high SWR from the end-fed has damaged the diodes in the 
KAT2 wattmeter.

Do a couple tests - set the ATU menu to CALP and connect a dummy load 
(an external wattmeter between the KAT2 and dummy load is helpful).
Set the power knob to 5 watts and do a TUNE - how much power is being 
delivered.  If it significantly higher than 5 watts on the external 
wattmeter and shows little power on the K2 display, then the KAT2 diodes 
have been damaged.

After that test, you should do a test of the base K2 PA transistors.  
Remove the KAT2 (physically remove it), and use the ANT jack on the base 
K2.
Set power to 5 watts and do a TUNE.  If the power on the K2 display and 
and the external wattmeter are close to 5 watts, then the K2 PA 
transistors are OK and you will most likely find the problem in the KAT2 
wattmeter diodes.

Don W3FPR

Ron,

I use macros to  change mode (USB, CW, PSK, RTTY, etc) and set bandwidths
and power levels.
Wish I could also turn VOX on and off, but supposedly that command is
coming.

I don't know where the idea started that the decode algorithm in the 
K3(s) would be a good as a stand alone dedicated program like MMTTY. It 
won't ever be simply from a processor and memory point of view. I'm sure 
the Elecraft principals have made no such claim so why do people still 
expect it?

It's a "gee whiz would you look at that" kinda thing more than anything 
else. Use it in a serious contest or DX pileup? Nonsense. Let the 
computer/software do what it does best and let the radio do what it does 
best.

We included RTTY/PSK decode/encode in the K3/K3S/KX3 to expand the range of conversational, no-PC-required digital modes available to the operator. I'm glad that our high-efficiency, convenient implementation suffices for many QSOs and casual contest operation.

If the communication requirements are more demanding and a PC is available...well, there's always LINE IN/OUT :)

  Anyone here tried rig control for the KX3 using fldigi and received a init:_IO error message? I've recently been dabbling in the digital modes and can't seem to find a specific answer to the issue. My web searches aren't helping much either. I've tried reconfiguring setting based on suggestions and instructions but can seem to pin point the solution. Im using windows 7 and a signalink unit. I can key tx manually but cannot get the rig controls initiate for using hamlib or rigCAT.
If any one can point me in the right direction for answers that would be very helpful.

Yeah, but I wish there was a definitive on or off as opposed to toggle by
macro.
Or, if we had the "If Then" construct in the macro language to see what the
current VOX status was and then decide to toggle it or not.

I virtually always do RTTY with MMTTY and 2Tone, but I also watch the K3 
decoder, and find it to quite good.

Message-ID: <CA+6EF7wJt97PVy7u9RPcnK7-yeF4V=CTeiQN+0rrHt1guVdHmw@mail.gmail.com>

Hi, I have updated to the latest P3 Beta firmware MCU 1.59 and have the
SVGA option installed.

It's working great, except with the previous firmware, with SVGA Data off,
DX Labs Winwarbler would display both decoded CW and  RTTY from the K3 and
with  SVGA Data on it would disable Winwarbler.

Now only  RTTY will display on Winwarbler.  CW is never displayed on
Winwarbler with SVGA Data on or off.  Could this be a minor bug in the Beta
firmware?

The new #RCF command works perfectly by the way.

Any ideas?

Before you do anything, back up the configuration, and save it in case

Have you loaded KX3.xml needed for RigCat? Get it at
<https://sourceforge.net/projects/fldigi/files/xmls/elecraft/KX3.xml/download>.
Also read the notes at the top of the KX3.xml file.(Can be opened with a
text editor.)

You may also want to try to control via flrig. You will need to read the
fldigi manual on how to set this up.

Latest files for fldigi are at:
<https://sourceforge.net/projects/fldigi/files/fldigi/>

Latest files for flrig are at:
<https://sourceforge.net/projects/fldigi/files/flrig/>

Chose the appropriate file for your operating system. Manuals are
available in the same directories.

Mentor assistance is available on the following Yahoo groups:

  * linuxham  - primarily for Linux and OS X users
  * NBEMSham  - support for using the entire suite in an EMCOMM environment
                all operating systems
  * winfldigi - for users on Windows OS.

Hope something here will help get you going.

Subject: [Elecraft] P3 CENTER button and SVGA display
Message-ID: <01d401d1819f$48fedb20$dafc9160$@gmail.com>

Hi Gang,

 

I have the P3 with SVGA option and a K3.

 

The firmware appears up to date, according to the P3 Utility.

 

I've set CenterEn: ON and use the CENTER button and the P3 knob to move DX
pileups more into the center of the display.

 

When I hold the CENTER button while in CENTER mode, the P3 display returns
the VFO A green bar to the Center position, and the red bar of VFO B to the
correct vertical position relative to VFO A.  

 

However, the SVGA is hopelessly confused at this point, and the VFO A green
bar and the VFO B red bar are incorrectly positioned.

 

A power-cycle on the P3 is required to return the SVGA to normal.

 

I thought I might be getting RF into the SVGA port - but now have discovered
this happens without any TX at all.

 

Any suggestions or further things to check will be greatly appreciated!

 

Thanks.

 

- 73 and good DX de Mike,  <http://www.qrz.com/db/k6mkf/> K6MKF, President -

Message-ID: <002101d181ab$922935a0$b67ba0e0$@sonic.net>

I just received a new K3/0 Mini and RemoteRig system and connected it via
LAN to a K3 that will soon be running remote.  Everything seems to work
except that the transmit audio is plagued by loud digital hash about 10 dB
below the mic level that does not occur when the mic is plugged directly
into the K3.  After reading a post from another user with the same problem,
I fed the mic directly into the RemoteRig and there was no noise.  I tried
both the front and side panel connections with three different microphones
that all worked fine with another RemoteRig system I am currently running.

 

While I am new to Elecraft products, I have used the RemoteRig equipment for
three years and I'm familiar with the settings, applications and
limitations, but it's clear to me that something is wrong in the K3/0.  This
is not the "click" caused by polling that was fixed with a recent update.
The user who had the problem last year said that there were numerous others
that had the same problem.

 

What is known about this and how can it be fixed, other than with my
'ham-strung' RJ45 jumper that brings the RemoteRig mic out direct?

I always chuckle how it is always the user's fault When the ISP chokes 
on an email - the message you get is to "resend the proper password" - 
or some such indicator that it is the user's fault. That appears to be 
the attitude with this list. The problem is with the user. At least, 
that is how I would interpret all those direct emails I received from 
other users.

Got news - in this case (and most cases) it was not.

This morning the list spit a bunch of messages out - but is still not 
completely up to date. Nothing was done here to cause this. Hence, the 
problem lies some place between the mailman.qth.net and the local ISP. 
Makes me think that mail-archive.com has a propagation problem. This is 
not an issue that will ever be solved by the user.

I am considering selling off my FLEX-1500 and Ten-Tec Argonaut VI to buy a KX3. It will mostly be used for vacations, Field Day or park and backyard portable. I will mostly use resonant antennas and do have an LDG Z-11Pro tuner (has internal batteries) which could be used, so not sure about the internal tuner and may eventually get the amp too. I mostly operate CW and some WSPR/JT-65HF and have a portable paddle. What options will I need for my types of operating? I am trying to not max out my budget.

Thanks,

Maybe you should be receiving the list *directly from Mailman* and not
using an intermediary server/service like mail-archive.com.  I do not

AMEN Lynn!
Download the Elecraft Utility for the KX3, KXP3 and KXPA100 if you haven't 
yet.
They are located at 
http://www.elecraft.com/software/elecraft_software_page.htm
The back-up configuration is in the Utility for each.

When you have time roam about in the Elecraft web site. You will need to 
learn how to download and install new firmware.
Elecraft updates the firmware from time to time. Both to improve it's 
operation (bug fixes) and better yet to add new features!

George,

Your understanding is correct.  Elecraft recently improved the heatsink 
with additional area.  The new heatsink is an "L" shaped metal that 
wraps around the bottom on the KX3 as well as covering the rear area.

The stock heatsink is quite adequate for CW and SSB modes, and you 
should be able to run at full power.

If you are doing digital modes with long transmit times *and* you want 
to operate at power levels above 3 (maybe 5) watts, then you may want to 
consider one of the 'aftermarket' heatsinks.

The KX3 will reduce power to protect itself if the PA transistors get 
too hot.

So you will find your answer by considering what modes you wish to 
operate, the transmission times involved, and of course will you be 
operating portable when the ambient temperature is HOT and the sun is 
shining directly onto the KX3.  Those are abnormal conditions, but if 
you expect to encounter those extremes, one of the aftermarket heatsinks 
may be a good idea - for normal operation the stock heatsink will do 
quite well.

73,
Don W3FPR

Phil,
     I would order the radio with mic and ATU. There are only 2 more real 
options, an additional filter and realtime clock with battery charger. I 
have all of it in mine plus a few 3rd party supplied options, however, I 
don't use the internal batteries and clock nor the additional filter as 
I use the 8KHz receive offset. everything else is already included. Even 
though you own an LDG ATU, I would still recommend the built in ATU. It 
is more flexible and is integrated nicely as a part of the system.

George,
     If you are a long winded digital operator, I would recommend it; it 
doesn't hurt and gives some additional safety. Other than that, Elecraft 
covered the issue of heat dissipation in the original design.

Chances are a new KX3 has the latest firmware. See page 25 of your KX3
Owner's manual for details of how to check it and, should an update be
released, how to update it. 

Lynn's recommendation to back up your configuration is a very good one.
That's explained in the Owner's manual too. It's not likely that you will
have an issue with the KX3, but more often with the operator, Hi! If you get
to changing things around in the menus,  discover that you are "lost" and
want it back the way you started, all you need do is spend a couple of
minutes reloading your saved configuration.

AMEN Lynn!
Download the Elecraft Utility for the KX3, KXP3 and KXPA100 if you haven't
yet.
They are located at
http://www.elecraft.com/software/elecraft_software_page.htm
The back-up configuration is in the Utility for each.

When you have time roam about in the Elecraft web site. You will need to
learn how to download and install new firmware.
Elecraft updates the firmware from time to time. Both to improve it's
operation (bug fixes) and better yet to add new features!

Before you do anything, back up the configuration, and save it in case you

I would skip the mic. QRP SSB can exercise in frustration, even with 
very good antennas. If you must use a mic, I would go for a compact 
computer headset and a break-out cable to split the mic to the KX3 mic 
input and the headphones to the headphone input. These cables can be 
found o the internet for about $5. Buy the headset on the basis of 
comfort and light weight. At home, use a Yamaha CM500 or similar Koss 
with that same adapter cable.

I agree with Jim?s comment.  When I operate portable with my KX3, I use my iPhone headset for my ears.  It has a mic of course built in but I never use it as I am CW only with the KX3 in portable ops QRP.  I don?t always operate true QRP (5 watts) but prefer to operate what I would call KX3 QRP at 10 watts using my external lithium battery packs.

I do have the Elecraft mic though.  But, minimizing cost was not my goal, instead my goal is to maximum toy collection.

I agree on the Mic and ATU, Phil. Not using an 
outboard ATU is a good thing for portability, and 
the Mic is a very good one.

The filter is also a good thing to have especially 
if you are near strong signals, so I'd get that, 
too. Internal batteries: Depends on if you plan to 
always carry external power source or not.

Bill,

I have extensive experience getting email delivered in a commercial setting
for our product that sends 1000s of status and report emails per day. While
it is wrong to blame the actual recipient, delivery problems are almost
always related to the recipient's email service, often an ISP of company.

We see this every day where we can see that our email servers have
delivered the email to the recipient's email server and yet the user never
has it delivered to his or her inbox. The usual reason is related to
anti-spam measures that ISPs employ. Most now discard a good percentage of
inbound email without even bothering to place it in a spam folder.
Sometimes, like gmail does all the time, the email is quarantined either
for a period of time or indefinitely pending manual release. This is often
done to see if this is a an email that is being sent to many other
recipients at the ISP, in which case it is probably spam.

Others are more helpful, sending our servers a rejection message saying
things line "Blacklisted" or "violates local email policy" or something
similar. Other times it is a temporary error of some sort and we get
rejections saying "excessive email rate", "user not found" or "mailbox
full". We can often see that this is an error, because after some number of
attempts or a few days, the "User is again found".

My point is that in all these cases, the delivery is failing on the "user's
side of the internet" even if they have no direct control of the receiving
email server. And short of coordinating with the ISP to get whitelisted,
there is not a lot the sender can do.

Regards,
- Brendon

I?ve had a lot of fun on QRP SSB with nothing more than a Buddipole vertical or end-fed wire on 20 thru 10 when the bands are good.  It?s more about ?persistence? than ?frustration? ;-)  I do usually run a whole humongous 10-12 watts as long as the battery holds out, and that makes some difference.  Occasionally, a DX or other station of interest (with a heart) will actually ask for QRP mobile stations to give us a break.

In any case, a headset/mic is a good idea, and I do use a CM500 with my KX3 occasionally, but I just don?t like sitting outside on a nice day buried in headphones.  And I wouldn?t want that to be the only option.  Probably 75% of the time I use the Elecraft mic and a small (self contained battery) powered speaker thingy from Best Buy.  Makes the time a whole lot more pleasant ? which for me is the whole point since I?m not a DX hound on QRP (or anything else) unless it just falls into my lap.  Besides, when there?s a rare one, you really have virtually no chance breaking through the bedlam and the guys running their 2 by 3CX15000 amps who invariably jump in for the 3rd time that day to say hello .. again .. and then rag on to ?update? the DX (and everyone else) about how bad their sore toe feels or what they had for lunch.  (What?s with those guys anyway?)

Now if you?re trying to run stations on SOTA/NPOTA/whatever .. different story, obviously.

The hand mic won?t impact your retirement plan, and you may be happy you have one, now or later.

I've recently been dabbling in the digital modes and can't seem to find a specific answer to the issue. My web searches aren't helping much either. I've tried reconfiguring setting based on suggestions and instructions but can seem to pin point the solution. Im using windows 7 and a signalink unit.

If you use Fldigi's RigCAT method, you'll need to edit the K3.XML file 
to suit the KX3 better.   IIRC someone said they had a KX3.XML file, but 
I forget who.

If you wish to edit the K3 XML file, use the excellent editor "Geany" 
(Windows or Linux) as that has the ability to format the listing and 
highlight the syntax of XML files.

Hamlib's K3 backend sort of works, but is less than optimum, plus Hamlib 
has serious functionality issues on many Windows systems I find...

Flrig:  "Mostly" works, but there are issues with the control command 
ranges (especially the RF gain, and Filter settings) while swapping A/B 
VFO's is fraught with trouble...

I've recently been working on the KX3 backend within Flrig and have 
sorted out some of the issues, but A/B VFO swapping is still buggy, plus 
one or two other much more minor wrinkles remain...    I've just not had 
enough of the right sort of contiguous free time to get deep enough in 
to even learn exactly what Flrig is trying to do to the radio that P's 
it off so much.

I'll contact Dave W1HKJ and get him to merge in what I have working so 
far, into the production run of Flrig.   But, that wont be this weekend, 
as we have a house full of grandchildren at this time, and I need eyes 
in the back of my head!

Though the K3 and KX3 share many features, the devil is in the detail 
down in the weeds, when you start commanding the things over a remote 
control link.

I have all the options plus big heat sink and the side handles/cover (purchased after the front got scratched in my day pack. 
In order of usefulness:
 Antenna tuner (integrated very well with radio) works well with random length wires when portable.
 Filter (a must have for field day operation but only used then)
 Hand mike (even smaller/lighter would be better when portable) never use the up/down buttons.
 Battery option (only used to extend my portable operating time when my external Lipro battery runs down).

If you don't use Win4K3Suite with your K3, KX3, or K3s, you might want to
check out this new video on the features of the product:

https://www.youtube.com/watch?v=htVlc9x0IoU&feature=youtu.be

Even if you have been using Win4K3Suite, you might discover some features
you have not been utilizing that you might find helpful in taking advantage
of your station.

Tom/*VA2FSQ *has added some new great features to support macros and
function keys, including WinKeyer support.   I can attest to the reduced
latency in CW mode that helps me time breaking the pileups more effectively
with the integration with my WinKeyer.

Tom continues to add features and functionality.  I currently use
Win4K3Suite during contests with N1MM+ including FLDIGI.  It is also very
compatible with a number of logs.  I use Ham Radio Deluxe log, only for the
log and rotor control.

I use the Win4K3 suite with both my K3 and KX3.  I run it on my Dell XPS12
and the KX3 when I am QRV.

All of our FD stations run Win4K3 with our KX3s.  When we give tours to the
public and press, they get a visualization of the bands.

Arcing represents a loss of energy, which for most power utilities means
loss of revenue.  For a while, a member of the extended family dated a
power line tech whose job it was to "sniff" the insulators along a 240KV
transmission line for the local utility on a regular basis.  It takes
strange people do that job.  :)

My wife spent a good part of her working career as an engineering
designer for industrial power and instrumentation projects including
generating and transmission substations.  "Low voltage" meant that the
insulators were less than a meter long.  :)

When arcing, they are generally visible (at night) and the arc noise can 
be heard when standing near the line(s) in question. That gives you the 
ability to locate the fire hazard.

Local fire departments have been known to take a very dim view of fire 
hazards - and they have amazing power to force the power companies to 
remove any and all fire hazards.

I know this from experience - it does work. Perhaps the same method 
would work in other circumstances also.

Good question.  It?s the DSP board from the K3S (the performance difference being the audio).  Maybe a supply issue, still (?).

It has a very different meaning in the wiring of buildings. Low voltage 
is less than 25V RMS or less than 25VDC, and has less stringent 
requirements for protection by being installed in raceways (conduit, 
cable tray, etc.)  Most audio, video, RF, and control circuits in 
buildings carry low voltage. And that's why 24V is used for "low voltage 
lighting."

Our Chicago SBE chapter toured the Argonne National Accelerator Lab SW 
of Chicago about 15-20 years ago.When the engineering crew talked about 
the hundreds of power amplifiers running "a gallon" to referred to the 
hundreds of Megawatt power amplifiers that powered the accelerator.  
They told us the operating frequencies, and in the parking lot outside 
the building, you couldn't hear a peep from them!

But I would be interested in how other contesters set up their rigs 

This is what I have been doing - 

	0) 	Narrow Filter enable (500 Hz)
	1)	Very narrow Bandwidth at times even 10-20 (hz?) is too wide.
	2)	Vary where I am listening up and down a little
	3)	Disable PreAmp
	
What other steps can I do to make my life (and the other stations I am working easier - I forgot how many times I sent R7?? or NR ??)

	Attentate (Just thought of this)
	NR Settings ?
	Notch filter ?

Hi,

I use a Genovation keypad connected to the P3, and hence the K3, for
all contesting... ?It allows built in macros to be fired with a single
keypress into the K3... ?See:?

http://nk7z.net/adding-an-external-keypad-to-the-k3/

for more info on the keypad.

I switch between very wide for listening around, and then zoom to
narrow... ?The steps are as follows:

1. ?As wide as possible, scanning around, zero in close to station by?
? ? hand.
2. ?Hit ALIGN button on Genovation Keypad. ?This centers the signal in?
? ? the passband, and on the spot frequency set in the K3 via macros.
2a. If split, hit the SPLIT +5 button, on the Genovation, this puts ? ?
? ? the radio in split, moves the DX to the left edge of the P3?
? ? screen, and then adjusts the span of the P3 to 6 KHz. ?I can then?
? ? see the openings, and the stations answering the DX. ?Lets me find?
? ? a hole in the crowd to answer in as well.
3. ?If too much QRM hit the Filter button on the Genovation Keypad,?
? ? this narrows the bandwidth to any filter selected using one button?
? ? press.
4. ?Enter data to log by hand, or if via spot it is already there.
5. ?Hit the NK7Z button on the keypad, this sends my call at a?
? ? selected CW speed, or triggers the memory if in SSB.
6. ?If station answers, hit the EXCHANGE button on the software,?
? ? or the keypad.
7. ?Press Wide bandwidth on keypad, then Goto 1. ?CLear SPlit if?
? ? needed.

The Genovation has the following filters set up on it:

2800, 1000, 750, 500, 300, all of which can be selected with a single
key press, for each mode.

If I want NB/NR, I hit the button on the keypad for NB/NR, but I
normally don't use either. ?Same for attenuation.

Once you get used to the keypad, it is like playing a piano, I can
operate the K3 and never even touch the radio... ?Wonderful for
contests...

Dave (NK7Z)

Looking for suggestions on some type of quick connect/disconnect for a ground

Also, is there one type of NiMH batteries to consider that might be
considered the best? Just rec'd my KX3 and haven't bought batteries. I have
been using the Pro Audio Engineering power supply.

Thank you-

Hi Tim,

I am not an 'expert' contester but I do enjoy the competition! First and foremost I think settings for contesting are 'personal'; what works for me, may not work for you. I use a K3 feeding an Alpha 9500 amp which feeds a 2-el 40m yagi and a 16-el tribander, both made by Optibeam and are up 70' and 80'.

For CW contesting today, get a really good contest program; I use N1MM+ and find it to be a really well written and very well supported contest program (and it is written specifically for contesting only!!), and it fully supports the Elecraft xcvr' s. N1MM+ will key the K3 directly via the DTR line on your PC RS232 interface cable, up past a little over 100 wpm! For my K3 I turn RIT on and use 'CLEARRIT' macro to reset the rcvr when people answer my CQ slightly off my frequency. While I normally run QRQ QSO's for chats, I find best results for contesting is to set my sending speed around 28 to 34 wpm. My K3 is loaded with narrow roofing filters especially useful for CW operations and I select the 250hz 8-pole filter and vary the DSP filter between 350hz and 200hz . Since I run an amplifier, I choose to sit on one QRG and call CQ mostly and only QSY when my Q rate drops below about 50 Q's per hour. When the Q rate drops, I then change to S&P, looking for any multipliers I have not yet worked. (N1MM+ will automatically show you how many Q's that one multiplier is worth!) 

Since I live on ex-farm land and on 15 acres, I seldom need to use the pre amp or the Attenuator and hardly ever need the NR and have no need for the notch filter. Hopefully others who have a large noise issue can supply you with their NR settings. Since you have an 'exciting' DX call sign, the 10 to 20 hz DSP filter setting that you use is probably necessary because of the large numbers caller's you have to your CQ. You might want to try varying your DSP 'SHIFT' to help dig out a readable call sign, in the midst of the QRM, when you get many callers.

I hope this will me a little helpful along with the other responses you will receive!

73 and good contesting,

Tom - W4BQF

There are two types of NiMH batteries, ?regular? and Low Self Discharge (LSD). LSD NiMH batteries have 10-20% less capacity that the highest capacity standard NiMH cells but lose much less of their charge over time. I use LSD NiMH?s because the charger in the KX3 has to be enabled manually and doesn?t continually top up the batteries. For scenarios where I?d really care about the extra capacity, I use an external lithium iron battery pack anyway

The generally recognized ?best? LSD NiMH batteries are the Sanyo Eneloop XX batteries (the black ones, not the standard white Eneloops which have less capacity). They do come at a significant cost premium, however, for the 10-15% extra capacity they have over less expensive NiMH LSD cells.

I bought high-capacity NiMH batteries for my KX3 and they were nearly 
always dead.

I replaced them with "pre-charged" (Low Self-Discharge) cells, and 
they're always good.

The choice is easy.

Thanks for all the comments on choice of options. I still need to sell my FLEX and Argonaut first but I have some definite ideas on how to order my KX3. The best thing I have learned about Elecraft products after owning a K2 and K3 is that whatever options you didn?t get on the original order, they are easy to add later. This list is a great resource whenever a question arises. I appreciate all the responses.

Subject: P3 CENTER button and SVGA display

 

Hi Gang,

 

I have the P3 with SVGA option and a K3.

 

The firmware appears up to date, according to the P3 Utility.

 

I've set CenterEn: ON and use the CENTER button and the P3 knob to move DX
pileups more into the center of the display.

 

When I hold the CENTER button while in CENTER mode, the P3 display returns
the VFO A green bar to the Center position, and the red bar of VFO B to the
correct vertical position relative to VFO A.  

 

However, the SVGA is hopelessly confused at this point, and the VFO A green
bar and the VFO B red bar are incorrectly positioned.

 

A power-cycle on the P3 is required to return the SVGA to normal.

 

I thought I might be getting RF into the SVGA port - but now have discovered
this happens without any TX at all.

> But I would be interested in how other contesters set up their rigs

On CW, my IF bandwidth is usually set around 250 Hz for Search and 
Pounce, a bit wider for Running (calling CQ) so that I don't miss 
off-frequency callers. When QRM is really bad, I'll go as narrow as 150 
Hz to copy a weak signal, but return to a wider setting when I'm 
finished with that weak station. When in S&P mode, I use XIT to move my 
TX a few hundred Hz off of zero beat to separate my call from others. 
When in Run mode, I use RIT (but not XIT) to tune in off-frequency callers.

Virtually all "contesters" use a contest logging program of some sort. I 
use N1MM Logger Plus, which is freeware. It is the most popular contest 
logger both because it is very good, and because it is free. Most other 
contest loggers are shareware. Contest loggers send messages that we 
pre-program before the contest (call CQ, send our exchange, send fills), 
check that a station we want to call is not a Dupe, and maintain the 
log. For SSB contests, the logger can play back voice messages that you 
recorded before the contest. For most SSB contests, I only record CQ 
messages. After the contest, it will automatically produce the Cabrillo 
file, a plain text file that is sent to the contest organizers to enter 
our score.

I try to avoid use of the NB, because it generates clicks and band noise 
from strong off-frequency signals. If band noise is bad, I DO use NR to 
pull out signals close to the noise level, and if the band is noisy, I 
leave it on all the time, because it takes the NR a few seconds to 
adjust to band noise and compensate for it. Whether or not to use the 
preamp or attenuator depends on band conditions. Generally the preamp is 
needed at its highest setting on the higher bands (6, 10, 12, and 15M), 
less often on 20M, rarely on 40M and below. On the lower bands, the 
ATTENuator should often be used.

I use the P3 extensively, with the SVGA option, to find activity on a 
slow band (like 10, 15 when they are marginally open), and to find a 
"hole" in which I can call CQ.

For some contests where it is permitted, or is permitted for the class I 
want to enter, I'll use the Cluster system to help me find stations to 
work. When I do that, I use VE7CC's excellent freeware CCluster software 
to filter spots. For most contests, I choose to see spots FROM stations 
within about 1,000 miles from me (I'm near San Francisco, so I choose 
all of W6, W7, VE7, VE6, NM, and CO), but I also choose KH6, KL7, and 
MD, because that gets me spots that show the stations in my area that I 
can't hear, but who I have to fit in between when I'm looking for a CQ 
frequency. Most contest loggers can be set to show those spots on a 
vertical band map, and to color code them to show them as a multiplier, 
not yet worked, already worked, non-workable in this contest.

Contest loggers can be set to send CW on the serial port (including a 
USB serial port), or using a dedicated keyer called a WinKey. WinKey is 
sold as a kit, and is easy to build. On some computers, keying via the 
serial/USB port can be choppy, and the WinKey solves that problem.

That's all I do during contests -- no fancy keyboards or other tools. I 
don't use K3 memories at all -- I use only those in the logging program.

Welcome (back) to contesting. It's the "on the air" activity I enjoy 
most. You would probably also enjoy joining a local contest club if 
there is one. I see from your website that you are considering LOTW. By 
all means DO put your log on both eQSL and LOTW. It saves those who want 
your QSL a lot of money for postage, and it saves both of you a lot of 
time. Some awards accept one or the other, but usually not both.

If you do not use the 2 meter module you can do as I have and use the hole
in the case for the 2 meter antenna. I used star washers to bite into the
metal and have a 1/4" or so of a small machine screw sticking out. It does
a great job of grounding the rig.

Hello
I was just on 20M everything working perfectly. I went up to take a shower, came back down and now there is 0W output power, all TX calibrations have failed and I can?t hear any signals on any band.

Would could possibly happened.

For grounding, I am partial to PowerPole (PP) connectors.
I use the 30 amp ones to quickly connect and disconnect
the radial wires for my movable vertical. You could use
a very short wire from your KX3 ground lug to a PP. If
you want to be "code" correct, you can get the PP connectors
in all colors including GREEN for ground.

Unsure of what may be the issue, but it would maybe be a worthwhile 
thing to restore from your last good configuration that you stored 
with the K3 utility. If you do that and there is still a problem, 
then it is not something with your software setup and if so, the 
answer would be outside the K3 or a failed part within the K3.

At least that would be one variable to be excluded.

There is a bug fix in the latest beta version of P3 firmware that might 
apply:

P3SVGA 01.33 / 3-7-2016

* Center Frequency in Tracking mode:  Fixed an old bug that caused the 
VFO A cursor to reset to center of screen when VFO A was tuned after the 
user had adjusted the center frequency offset using the CENTER function 
in tracking mode.

Tim,

You might also consider "riding the RF gain" route, depending on how
bad the pileups are.

Turn AGC off, turn up the RF gain, and modulate RF gain as needed to
discern signals.

Be careful though, in this mode AF gain is mostly unbounded, i.e.
you'll hurt your ears and/or headphones if a signal is really loud.

For me, I use that mode sometimes when signals are weak, it seems to
allow for better hearing of weak signals.

YMMV, 73 de N6GQ

I just updated my P3 to the beta firmware.  The symptom Gary described also
occurs here after I switch between SVGA data mode on/off.  I find that I
now have to power cycle the P3 to get CW decode to begin flowing data to
Commander->WinWarbler again.

I did not have to perform a P3 power cycle when switching between SVGA data
on/off in the current production firmware.

Re: "...is there one type of NiMH batteries to consider that might be?considered the best?"

The term "the best" is always a difficult one for engineers, but I still have a three year old set of Panasonic 2000mah low self discharge ?(LSD) cells in my KX3, and they are still working great. ?The chemistry in these is identical to the Sanyo Eneloop cells, which are available in at least 2500mah LSD cells now. ?Panasonic ?ended up buying Sanyo, but maintained and continued to improve the Eneloop line.

One caution with any rechargeable cells is don't discharge them below their minimum discharge voltage, which is about 1 volt per cell for NIMH cells. ?The KX3 battery warning and shutoff will protect them nicely.

Don't even consider cells that are not LSD cells. ?Those will self discharge to a voltage below their minimum discharge voltage, destroying themselves in the process.

I used Eneloops for years to power multiple camera flashes with no problems. Recently switched to PowerX batteries of a slightly higher capacity and they are doing well too. The original Eneloops (now 5 years old) are still meeting 90% of their original capacity after numerous cycles. I test them all periodically with a charger I can also recommend:
http://www.amazon.com/La-Crosse-Technology-BC1000-Battery/dp/B004J6DLD4
and with the CBA analyzer from West Mountain Radio.

Either brand battery should serve you well.

Don't forget the K3/K3S has an audio limiter that you can set to protect your ears when the AGC is off (CONFIG:AF LIM). 

I'm assuming from the notations that you are using a K3/K3S since it's not noted in the Sj.

Tim,

You might also consider "riding the RF gain" route, depending on how bad the pileups are.

Turn AGC off, turn up the RF gain, and modulate RF gain as needed to discern signals.

Be careful though, in this mode AF gain is mostly unbounded, i.e.
you'll hurt your ears and/or headphones if a signal is really loud.

For me, I use that mode sometimes when signals are weak, it seems to allow for better hearing of weak signals.

Be very careful with the AGC off... ?The K3 has enough dynamic range to

If you run with AGC off, you'll probably want to use CONFIG:AF LIM to establish an upper volume limit. See AF LIM in the menu listings.

That's also what I do with all my gear -- stranded wire crimped and 
soldered to a spade lug on one end and soldered to a PowerPole on the 
other. Then single conductor power pole jumpers of suitable length from 
one piece of gear to another.

I used to operate CW with AGC OFF, but a loud signal would come 
along and trigger the AF Limiter, which causes gross distortion.

Now I operate CW with fast AGC , AGC SLP = 0, and AGC THR = 20. 
It's almost as good as no AGC , and you don't have to worry about 
the AF Limiter.

Ha, ha!! It does that. But many of us O.T.s worked for years listening to
the thumps and howls of an overloaded receiver as our "sidetone" while
transmitting or listening to monitors using sawtooth oscillators to generate
the tone. 

But, really, the limiter is an ear-protection device to keep your hearing
intact for the few seconds it takes to back off the gain. 

I'm an old commercial CW operator from the 1950's and grew up with the audio
gain set fairly high and controlling the listening level with the RF gain.
But modern AGC such as the K3/K3S has is so good I'm getting out of my old
habits.

Hi, Tim - From an AGC perspective, I use the same approach K6LL does, seems
to work well for all cases except when I am running, get spotted and get hit
with a dozen stations all calling zero beat on the exact same frequency.
That is the scenario where I occasionally back off the RF gain or adjust the
Shift control off of my 600 hz pitch frequency a bit. As a fairly rare DX
station in a contest, you will probably hit that condition more often.

On pre-amp/attenuator, for conditions here on the East Coast, I have the
pre-amp on for 10 and 15m, usually off for 20, always off for 40 and 80.
During a 160M contest, I will turn on the attenuator on 160M but for most
multi-band contests I find it is usually not necessary there. But,
conditions where you are will likely be very different.

I leave all NB/NR off for contests, with lots of loud signals on bands they
seem to add more noise than they remove. Since the notch filter is manual
for CW, I never use it and certainly never in contests.

On  the PVRC mailing list we had an interesting discussion about filter
bandwidth and CW pitch - generally  pitch or center frequency between 400
and 600 hz was preferred, much feeling that lower meant that when adjusting
RIT you would be causing a larger % frequency change in the signals and thus
differentiating more. I usually run my 500 hz filter, rarely going lower
unless there is some multiple snuggled between two loud running stations!

Of course, there is always the Fred K3ZO data point, though he isn't a K3
user: he believes in leaving his filters wide open for CW contests and does
the filtering between his ears... That only works if you have a similar CPU
between your ears!

Gary,

If you are thinking of the DSP processing, that is done at 15kHz.
The audio response can be from 50Hz to 4000Hz and depends on the setting 
of the shift/width or HiCut/LoCut.

I dunno, the K3S audio actually isn't much better to my ears. Yes, it's a
little better on my K3S compared to my K3, but still kind of shrill and
fatiguing to listen to for long periods of time. I'm not sure it'd be worth
spending a ton of money on to upgrade if there was an upgrade path. 

Don't get me wrong, I love my K3S; the best rig you can buy, IMO. But I
still strongly prefer the smooth, low sounding audio of my K2. I never get

Message-ID: <CAMFZV83XmzbP1Pyh9iwzFb+AO9zE=tpqCwNCJrpmt9+iegDpDw@mail.gmail.com>

Good day,

I wrote this about a week ago and nobody responded so I am asking
again.  Maybe Wayne or Eric can field it:


I am programming Macros for my KX3.  Recent financial issues have
relegated me back to just my trusty KX3 for all things HF.  When in
the shack, I usually operate low power digital modes and have my macro
nearly perfect.  The one parameter I cannot get right is to switch
ESSB so I am able to TX in the upper part of the JT area and use
JT9-ESSB works great for this!  As you can see below, I am trying to
use the MN096 and a toggle (MP00) to set the bit to on, but it does
not work.  I am certain it is just a syntax error.  Also, for when I
am doing voice and SOTA, I would like the command to do the opposite
and turn off ESSB.

Digital Macro:
TE-00-00-00-00+00+00+00+00;PA0;MG001;AG004;BW0400;IS

Does a decent speaker and amp being fed from the speaker out sound any
better? ?I have a computer speaker on the K3 now, and I also want
better sound...

Well I don't want to complain _real_ loud either lol. The audio on the K3S
really is better. But only slightly - not better enough to spend money on an
upgrade for the K3, imo, which is kind of what I was responding to.
Basically, save the money for filters, etc....

A good set of hi-fi headphones helps too, but I definitely still tire of my
K3S in a fairly short time even with headphones, especially if the band is
noisy. I find myself engaging the DSP and monkeying around with it rather
than concentrating on QSOs to try to relieve my poor ears on a noisy band.
Course it's even worse with my K3 lol. I've not found the equalizer to help
that much either with either rig.

Might just be my aging ears too, so take my comments with a grain of salt.
And when I'm /p, I'm usually at around 10,000 feet above sea level out in
the woods miles away from industrial noise sources. My K2, K3 and K3S are
all quiet as mice in those conditions, but by far my K2 is the preferred rig
to run there, even without the creature comforts of the K3/K3S....

73,
W5QD

Hi Randy,

You need three digits with the MP command. After the MN096, use "MP001;" to turn ESSB on or "MP000;" to turn it off.

The nominal 2nd IF is 15 kHz. In practice it varies from 13 to 17 depending on the operating mode.

Change the audio equalizer settings for received audio. When using a headset
you can tune the audio to your ears pretty well. 
If you don't know what I'm talking about check the owner's manual  page 37,

Do you listen on the internal speaker or on headphones? CW or SSB? Have 
you used RX EQ to shape the tonal balance? How do you set the IF 
bandwidth and centering? If headphones, which type/model? If external 
speaker, which one?

I'm retired from a career in pro audio, including lots of live 
recordings of acoustic jazz. My operating style is to use the speaker 
only for casual monitoring when I'm doing something else in the shack, 
and to help me tune in digital signals. I listen mostly on headphones, 
both Yamaha CM500 and Sony MDR7506. The Sony headphones are widely used 
in recording studios, and the sound of the CM500 is pretty close in 
sound quality. I'm quite satisfied with the sound of my original K3s. I

There's also a missing semicolon at the end of the first macro.  SWH09

I use both the internal speaker and a set of Sony headphones (not comm.
style, but basic hi-fi, can't remember the model number offhand) on
primarily CW but on very rare occasions I'll go up to the SSB bands from
time to time for listening/entertainment purposes. I do own a microphone,
but I'm not sure where it is right now.

But speaking of SSB, I will say that SSB is where the difference from the K3
is most noticeable, even through the internal speaker. Not an order of
magnitude better, but noticeable. So for you voice ops it may be a more
worthy upgrade? Voices are definitely flatter and smoother sounding through
the K3S.

For casual listening and for comparison with my K3, I run the BW at 2.7khz
with the center at the stock 1.5khz (IIRC). As I noted above, it's in SSB
signals that I suppose there's a more noticeable difference but the regular
noise when operating CW still has approximately the same shrill quality on
both rigs (headphones and internal speaker). It's hard to quantify, but it's
just has that harsh, upper midrange kind of rasp that the K3 has as well.

For equalization, I've tried reducing the upper mids and boosting the lows
to emulate my K2, but it doesn't really replicate the K2 regardless of
settings. So I just leave those flat.

Finally, I should mention I do have some mild hearing damage from many years
as a musician, so I just may be more sensitive to heavy mids/upper mids
types of equalization than others. So again, just take my comments with a
grain of salt. Just because I can't hear much improvement doesn't mean there
isn't an improvement or that others won't benefit from it :).

In this day and age, with PC soundcards and excellent freeware audio
spectrum analysis software (like Visual Analyser), I wouldn't settle for
subjective opinions like "shrill and fatiguing."  Feed whatever audio output
you're listening to into your soundcard and run a passband plot of your
favored radio against the K3s and TELL US why you don't like the K3s sound. 
And then "fix it" (i.e., your preferred sound) with the filter and EQ
controls.  I'm assuming, of course, that you're listening through the same
speakers or headphones on both radios.

Folks, this ain't rocket science or magic.

My apologies fellers, I didn't mean to turn this into a
let's-bash-the-K3S-audio thread LOL. Probably what I should have said is
something less absolute. Perhaps something like I personally don't notice
much of a difference between my K3 and K3S but that doesn't mean there isn't
a difference period that noone else will notice.

As for the why's and wherefore's of what I don't like, I've noted that in my
other responses. Again, for me, it's the upper mid kind of rasp of the band
noise that I find to be similar between the two rigs. And what I find to be
much better on the K2.

Again, just my observations - I didn't mean to sound like I'm making general
statements, that's my fault for which I duly apologize.

Funny you should post this - I was just about to send out a Kudos to Elecraft
support for my second K2 which I'm in the process of building right now. It
was missing a front panel switch in the FP board kit; I sent an email to
parts at elecraft.com on Friday about it. Richard, AD7FZ at Elecraft responded
in less than an hour and the switch is now bouncing around in the USPS truck
on the way to my apartment right now. So I should be able to resume
construction on it this eve. after work. 

I've never had to use Elecraft's support (their products really are that
good) and this was the first time I ever had to and it's outstanding!

So with my Kudos out of the way, my new K2 kit is ser. no. 7658. I ordered
it about 3 weeks ago, so that's probably at or near the top of where their
ser. nos are now. As far as I can tell it's identical to my previous K2
which I built 3 or 4 years ago (ser. no. is 69- something IIRC).

Hi Dave, 

The slowest update rate will be when the SVGA is running 1920x1024 and in
fixed tune.  Try going to a lower resolution (which will still look pretty
good on a hi-res monitor).  I usually run 1280x1024 or 1440x900.   The SVGA
is performing a 2048 point FFT, while the P3 is 1024, there's also
considerable overhead when in fixed tune mode which adds to the slowdown. 

Kind regards, 

Paul

LS,

If your problem is more related to "band noise", you may want to 
investigate the AGC Threshold and Slope settings on the K3 and K3s.
To my ears, the K3/K3S sounds a bit 'noisy' with the default AGC 
settings.  Increasing the Threshold and decreasing the slope may help.
For information on evaluating the results of any changes, refer to the 
"Noisy K3" article on my website www.w3fpr.com.
Pay particular attention to the points about observing the results 
during pauses in a transmission.   Attempting to listen only to the band 
noise with no signal present will result in changing the settings in 
exactly the wrong way.

Ok thanks for the suggestions, Don. I should also mention that the other
posters are quite right to call for objective, independent measurements to
verify impressionistic judgments like my earlier ones. I stand by "shrill
and fatiguing", :), but I concede that's just a personal judgment based on
my particular hearing.

I'll take a look at the AGC settings, though to be quite honest, I think
they're already ideal on both my K3 and K3S. I can't see how the AGC on
either could be any better? 

Thanks es 73,

I have always felt the K3 was a looser in the audio department - but, 
with the many menu settings available - most of the problem can be 
mitigated.

There a lot of things that can be done with the menu settings on the K3 
(presumably on the K3S also) that effect the RX audio - EQ settings, AGC 
settings, etc. I have posted my favorite settings in the past - it took 
weeks and weeks of tinkering to find settings for common armchair copy 
listening. I do use Behringer MS40 speakers also (no RF problems ever 
experienced).

The really sad part: My Kenwood TS480 out "sounds" my K3 right out of 
the box. Just saying a fact, so no flames please.

My point was that free tools are readily available to all of us to conduct
a quick investigation into exactly what the sound differences are and to
tailor the sound of a K3/K3s to our liking.  There's absolutely no reason
to continue to use a radio that is "shrill and fatiguing."  By all means,
investigate it, adjust it and FIX it.

They K2 might be old school, but you got to love the sound they have with CW. It is so easy on my ears.  
I almost sold my K1 4 band with 2 extra band boards to get another one.

All excellent points. My personal fix is to use my K2 at home where the band
noise is bad (I refuse to mix computers and ham radio at the same time, so
this may not be the fix you have in mind :) ), but when I'm /p, it's a
non-issue. I use all 3 of my rigs when portable with no audio issues.

Yep, I like my current K2 (#6882) so much and enjoyed building it so much
that I just decided I had to build another one lol... I guess you can't have
too many Elecrafts....

Speaking of that, I got the switch from the mailman and just soldered it in.
So onwards with the build...

Berry,

Actually it is quite complicated to define what is wrong with the
"sound" of something... ?What makes audio "fatiguing", exactly? ?I
can't say, and no amount of listening to it, or playing with the EQ has
fixed it in my case... ?

I used to work in a recording studio, as a mix engineer, (way back
when), and recently was in charge of the construction a Dolby
certified, (almost fully digital), mix down room for movie sound design
a few years ago... ?This was one of those rooms within a room on rubber
bumpers sort of thing... ?So I know a bit about audio.

Nor does using some non certified soundcard does not sound like the
path to pristine audio...

Friends,
     Perhaps it is because I largely operate CW but for me the original K3
audio is just lovely.    I am 71, my hearing is not so great but I use the
lowest pitch possible around 360 Hz and have RX EQ set for good performance
at low frequencies.   It is just a sweet sound to me and so restful.   Maybe
if I was a phone man the story would be different though I do monitor SSB
and work it for rare DX and it also sounds good.    

     Could it be that the great flexibility in setting up the audio results
in some people being put off as they have not found the sweet spot for their
ears.    I seem to remember a few years ago many people had troubles with
the FT2000 because it was complex to set up.   There were also people who
did not like the Orion II again because setting the radio up initially was
problematic for them.   

     Now I may be completely wrong in my analysis of this situation and
please God no one feels their toes have been trampled.   This is not my
purpose but for me the radio has a wonderful warm sound.   We are all
different.   Some people like a Sicilian Pizza while others like a
Neapolitan Pizza.

                        73 Doug EI2CN

Subject: Re: [Elecraft] K3S audio board for K3 upgrade?

Well I don't want to complain _real_ loud either lol. The audio on the K3S
really is better. But only slightly - not better enough to spend money on an
upgrade for the K3, imo, which is kind of what I was responding to.
Basically, save the money for filters, etc....

A good set of hi-fi headphones helps too, but I definitely still tire of my
K3S in a fairly short time even with headphones, especially if the band is
noisy. I find myself engaging the DSP and monkeying around with it rather
than concentrating on QSOs to try to relieve my poor ears on a noisy band.
Course it's even worse with my K3 lol. I've not found the equalizer to help
that much either with either rig.

Might just be my aging ears too, so take my comments with a grain of salt.
And when I'm /p, I'm usually at around 10,000 feet above sea level out in
the woods miles away from industrial noise sources. My K2, K3 and K3S are
all quiet as mice in those conditions, but by far my K2 is the preferred rig
to run there, even without the creature comforts of the K3/K3S....

That's been my experience too, "really great sound" is somewhat akin to 
pornography ... as Justice Stewart said, "Impossible to objectively 
define but I know it when I see [or hear] it."  I inherited an SX-28 
with the large bass reflex speaker a number of years ago.  As a ham 
receiver in the 21st century, it left a lot to be desired, but it really 
"sounded" great on BC stations, and those stations on 75 at night 
pretending to be BC stations.  I can't define "fatiguing" either, but 
running AFSK at 915 Hz MARK, I start getting a headache after 4 or 5 hours.

My hearing is severely compromised, and I never use the internal K3 
speaker and have never had anything plugged into the EXT SPKR jack.  I 
have a Heil Proset from Elecraft and recently acquired a David Clark 
aviation headset.  K9YC gave me a tip on the RX EQ to get the equivalent 
of about 30 dB of equalization out of it.  My settings approximate one 
of the "programs" in my hearing aids [30 dB isn't nearly enough but it 
helps] sufficiently that I can dabble in NAQP and SS SSB.

My TS-480 also sounds better than my K3.  My K3 was sent back to factory to
see if there was an audio issue with my particular K3.  They compared mine
to a factory unit, using an audio spectrum analyzer and noted that my K3 and
a new factory K3 were "the same".

The TS-480 just sounds better to these ears.

Oh, and it is magic........

Wayne, is hardware AGC still "on" when (software) AGC is set to "off"?

Subject: [Elecraft] KPA100 tools
Message-ID: <1458590816472-7615415.post@n2.nabble.com>

Hi all,
And speaking of the K2... I can't recall if I asked this several years ago
on my first K2 build when I was contemplating this exact same question the
first time, :),  and I couldn't find this specifically in the reflector
archives either.

Are there any specific tools for building/aligning/testing the KPA100
_other_ than the ones listed in the manual that are either required or very
strongly suggested?

I may go QRO in my now-being-built K2 but have rejected my "plan A" of an
external amp. So may do the KPA100. It looks like a wattmeter is almost
mandatory, but are there any other alignment tools needed?

I have a 100W dummy load, will get a large batt (that I'll use with it /p)
and have a DMM. And the compliment of tools spelled out in the manual which
I'm using to build the K2 to start with.

tnx es 73,
LS
W5QD

Hardware AGC is ALWAYS on.  It simply protects the ADC from dynamic range
overload and doesn't come into play until signals are s9++.

Well .. I'd get a headache listening to most ANYTHING after 4-5 hours.  The symphony in Bass Hall, or even good vinyl on a great turntable/arm/cartridge and a very good amp and very good headphones is no different.  

Maybe I just found the "right" speakers for my K3.  They're old RatShack (RCA) speakers with linaeum tweeters.  I have a lot of them, and use them on everything (new, old) in the shack.   I've never  found a powered set of "computer" speakers worth bothering with ... and I've tried quite a few not so cheapie ones, or the usual-suspect ham speakers.  I haven't tried the Elecraft offering yet, but probably will at some point. 

After the LPF daughter-board update (or rev D DSP) I haven't had an issue with anything related to K3 audio.  And certainly nothing I'd call a "screech".   The internal speaker is the speaker of last resort. My RX EQ is set to flat. 

That said, I'd still probably buy the updated DSP board for the improved IMD performance. Just because ....

LS,

The tools listed in the KPA100 manual are quite sufficient.
To set the PA bias, you do need a means of measuring the current rise 
for the PA idle current, and most DMMs will suffice - you will have to 
measure a current rise of 400mA.  I use a dedicated DMM on the workbench 
set on the 10 Amp scale for that purpose.  Since you are doing only one, 
a dedicated DMM for that purpose is not economical.  Use your existing 
DMM connected to measure current.

The only other things I use are a precision 25 ohm and precision 100 ohm 
dummy load.  Those 2 dummy loads allow me to more accurately set C1 than 
I am able to do by measuring the DC voltage null as instructed in the 
manual.  When the wattmeter bridge is correctly balanced, the SWR shown 
by both those loads will be the same.  After adjusting C1 so the SWR 
reading for both loads is the same, I can easily set the REFL pot 
exactly for a 2.0 SWR.

If you do not have the capability to produce a 25 ohm and a 100 ohm 
dummy load, then simply follow the instructions in the manual, and it 
will be close enough for proper operation.  The KPA100 throttles power 
back if it detects an SWR in excess of 2.0, so this is not a critical 
setting and those tools are not required - this is just a refinement 
that I do on my repairs.

73,
Don W3FPR

My two cents:

Never cared much for audio quality of the internal K3 speaker.  I use 
a very old 8-inch round National Radio speaker (probably 4-ohm as was 
most of the 1950 era stuff).

But when I need to dig out a signal from the noise I use my trusty 
SONY MDR-V600 headset (definitely used for CW).

I'm looking forward to when I next purchase hearing aids and will get 
blue-tooth capability to directly listen to the radio without use of 
speaker/headset...probably a couple years away on that.

My KX3 uses West Mountain Radio COMspkr's

The sounds being described are probably not just related to frequency
response, but to any type of harmonic, intermod or digital distortion, or
noise that is created in the final IF and analog audio stages of the radio.
This was referenced by Rob Sherwood in an early review of the K3 and
demonstrated with an audio spectrum analyzer.  A CW tone with these
characteristics might be described as "raspy", "brassy", "busy", or with
some other term audiophiles like to use, and in any case, would likely lead
to fatigue.  

If this is the case, equalization may mask it but won't fix it, and could
make the problem worse.

My TS-480 also sounds better than my K3.  My K3 was sent back to factory to
see if there was an audio issue with my particular K3.  They compared mine
to a factory unit, using an audio spectrum analyzer and noted that my K3 and
a new factory K3 were "the same".

The TS-480 just sounds better to these ears.

Ok thanks Don. That reminds me, my dummy load is eons old, so I should check
and see if it's still 50 ohms. And I believe my DMM has a 10amp setting that
may work for the bias setting, but I'll check. Also I have a very old MFJ
manual ant. tuner with an analogue wattmeter in it (assuming it still
works). Will that be sufficient for the items requiring a wattmeter or will
I need something more precise than that?

Thank you,

Another BTW, I'm definitely not asserting any _distortion_ of the signals or
tones in either radio. Both my K3 and K3S are giving pure clean tones and
voices. My complaints are only centering around (what I believe to be only)
the equalization in the audio, particularly the mid/high frequency noise.
Though as I said the K2 audio is a tough act to follow and I'm a bit spoiled
by it. 

The only time I have any impurities at all are with agressive settings of
the noise blanker or DSP with certain types of wide-band noise, which is
entirely expected.

So just want to clarify that I'm not describing any distortion products at
all. Just aging hearing mostly hi hi..

So true! 

I use tube audio gear. My Audio pre-amplifier is a McIntosh C2500 and 
I regularly use the USB input to its internal digital soundcard. The 
sound from that preamp is magnificent. When I ran the same source to 
a USB soundcard, bypassing the McIntosh digital card, with that  
signal sent to the Mc preamp & then to the amplifier, the audio was 
pitiful in comparison. The difference is remarkable in depth and 
transparency. The better soundcard stands out like a sore thumb. 

The quality of the soundcards do make a tremendous difference and 
with that said; I do prefer the sound of my K3s to the K3.

Look at the RX current drain on both radios. A K3 comes in at about 1A, 
1.1A with the new KXV3B preamp or the old PR6 installed. This is the 
result of Wayne's philosophy of optimizing for portable/battery 
operation, and it leaves the speaker output stage a bit low on current 
for those who want/need it loud.

And it's more than frequency response. There's analog distortion, both 
in the electronics and the loudspeaker. And there are distortions 
associated with A/D and D/A conversions, and the number of bits used.

Early production K3s (2008-9) had the design error of placing 600 ohm 
resistance between the line output stage and the transformer, which 
caused the transformer to produce distortion, even at pretty low signal 
levels. Pro audio circuits have not used 600 ohm inputs and outputs for 
at least 40 years, but too many manufacturers of ham gear (and even 
broadcast transmitters) never got the memo. Pro output stages are about 
100 ohms, that value chosen to prevent instability when the stage drives 
the capacitance of a long line, and pro inputs are around 10K (so that 
the output stage driving doesn't have to provide current.

Confused I am.

So....if SSB audio was not an issue on the K3, 
then why did Elecraft seek to improve it with the 
K3S initially touting it as one of the featured 
benefits of their next generation K3?

This SSB audio debate as been an acknowledged 
issue for many users for a long time...on this 
list and elsewhere. I notice that the December 
2015 revision of the K3S FAQ's now state that the 
revised DSP board for the existing K3 platform 
"may be available later in 2016" which is very 
different that was originally indicated in the 
FAQ's back last year.

After 7 1/2 years with my K3, using all 
combinations of filters, settings, RX EQ settings, 
speakers and headphones, last October I finally 
found the solution to my K3 RX SSB audio 
displeasure. It's called a TS-590SG. And it has 
one-touch-button band stacking registers to boot.

No regrets.

YMMV.

Elecraft must have decided that having already built six K3 they needed to
make building my 1st K3S a challenge. They succeeded

 

It all went together easily enough despite some issues with K3
photos/figures appearing in the K3S manual (eg Figure 91)

 

It powered up fine and the VCO passed self test, so time to hook up an
antenna. Nothing could be heard despite putting the RX on the TX7EU pileup.
As a check an HP signal generator was hooked up to the antenna port. It
couldn't hear -50dBm. Neither could this level be heard through the rx in
port or the Xverter port. The radio was dismantled, all connectors checked,
EEinit done, no improvement.

 

Time for more coffee, during which an inspiration. When I put the subrx into
the k3 I remembered I had to remove a link in the KRX3 back connector.
(J64A) So I searched the K3S manual. It appeared not to need the link as it
was not shown in "Figure 31. RF Board Partially Assembled." or on the photo
of the main rf board on Page a-14  or on "Figure 94. Installing the KBPF3A
Option Board." BUT I noticed a link still shown on the legend on the PCB and
its removal is still shown in fig44 of E740126A installing the KRX3A subrx.
"Nothing ventured nothing gained", so I stuck a resistor lead in  the W4
link and the K3S burst into life. Sensitivity returned and the K3S was back
to full health

An hour was wasted fault finding , making this the longest Elecraft build so
far

LS,

The KPA100 wattmeter calibration will be as accurate as the accuracy of 
the external wattmeter used.
The real question is -- How much can you trust your wattmeter at the 20 
watt and 100 watt levels?

Exactly!

I remember the trail of audio tears well.
The difference back then being they had never heard a receiver as good 
as the K3 and all it was picking up compared to their Yaecomwood. 
Couldn't possibly be their favorite old radio had been feeding them the 
RF equivalent of mush and passing it off as "great audio"?

They improved the IMD of the AF amps.  A good thing which doesn't mean it was an "issue" for most to begin with.

Hi Ron,

That review of the K3 audio by Rob Sherwood was on a very early K3. We quickly 
addressed the high freq harmonic issues (most of which were above 4-5 kHz and 
were more than 50-60 dB down) with a K3 DSP board revision that included a 
change to a beefier low ESR power supply filter choke feeding the audio amp and 
the addition of an audio LPF that rolls off above the DSPs max output of 4 kHz. 
We made even more audio improvements to the new K3S DSP board's audio chain.

On another note, Rob has run spectra on the newer K3S DSP and he has noted it is 
substantially improved over the first K3 he tested almost 7 years ago.

One thought for those using the 2.7 or 2.8 SSB filters. Try reducing the DSP 
bandwidth to 2.4 kHz or so, and shifting the center freq. down 100 Hz.  Many 
other radios have a 2.4 kHz SSB filter, and while it does restrict the audio 
fidelity as compared to the 2.7/2.8 kHz filters, the reduction in the upper 
cutoff to 2.4 kHz reduces the amount of high frequency band noise and 
interference, which may account for what some construe as a 'smoother' sound.

Also note that the stock 2.7 kHz filter has a much slower roll off than the 
optional 8 pole 2.8 kHz filter, and as a result may hear more higher frequency 
RX components.

Lastly, try listening with our new external SP3 speaker for the K3S and K3. It 
has an engineered audio response for a very clean and 'smooth' flat response, 
without major resonances.   :-)

73,

Eric

Many "traditional" transceivers also have a 3 to 6 dB per octave roll-
off in audio frequency response above 800/1000/1500 Hz (depending on
the manufacturer) which limits the high frequency "crud".

While there are some who have a "religious" opposition to using RX EQ
in the K3/K3S, I've found that setting the 3200 Hz "band" to - 6dB (or
-10dB) greatly helps with the sound on SSB and setting both 2400 and
3200 to -16dB is useful in CW.

Well... that may solve the audio problems - Kenwoods do sound great - but
then you end up with everything else in the rig inferior with that solution
hi hi.... 

But seriously, Eric's suggestion of shifting the passband downward is one
that I've used on my K3 in the past to help calm down my beat up ears, and
it does work. The result still isn't as nice as my K2, but it helps.

As for the general question of if-it-wasn't-broke-why-was-it-fixed, I'd say
that just the normal progression of improving your product. That's what
makes Elecraft such a good concern and their products so good; even tho they
got to the top of the performance heap, they're still working to make their
rigs better. My complaints about the audio notwithstanding, they still did
make it better in the K3S regardless.

That's what really differentiates Elecraft from their competitors, IMHO....

Subject: [Elecraft] Elecraft K3 interferes with IC-2820???
Message-ID: <B3FC7E64A3DF41A9A7EAC69D20491825@homePC>

When I operate on SSB, any frequency at 100 + watts the display of my IC-2820 signal strength meters almost peg out on both sides of the display. When i operate QRP (5 w on cw, 7097Khz there is no indication.   When I use my IC-746 PRO at 100 Watts on the same antenna there is no indication on the IC-2820 signal strength indicators.  All of the Elecraft equipment is factory assembled.

I have checked my coax cabling from the K3 to the KAT200 to the KPA500.  I use a single point station ground for everything (both rigs).  Any ideas??

Subject: [Elecraft] New KX3 field-test firmware allows remote control of
	PSK31/PSK63 selection, etc.
Message-ID: <12638C1A-191F-42B2-AF69-2DD543E3FD8A@elecraft.com>

Hi all,

I made a few changes to the KX3 firmware. I'd be happy to send it out to anyone interested in the changes. See release notes below.

73,
Wayne
N6KR


* * *

KX3 MCU 2.52 / DSP 1.37, 3-19-2016

* HOLDING RIT CLR UPDATES RIT OFFSET AT PX3 PANADAPTER.

For software developers:

* POWER-OUTPUT CONTROL COMMAND (?PC?) FIXED:  The "PC" command now correctly handles the KX3?s power ranges (up to 12 W or 15 W depending on band).

* PSK31/PSK63 SELECTION (ETC.) VIA REMOTE COMMAND:  When the DATA submode is being modified under remote control, a software application can now select between PSK31/PSK63 using the UP/DN (VFO A) control commands. Similarly, UPB/DNB (VFO B) can be used to select the desired TEXT decode mode (DEC OFF, TX ONLY, RX THRn). To determine the current state of any of these parameters, you can use the DS or DB commands. Refer to the Programmer?s Reference for further details.

Fellow Hams,
		Many thanks for the guidelines and suggestions?. I will try and experiment with some/all of those suggestions.

	I had been running with AGC Off - but after having being deafened by the POPs of several RU using Kw - I went back to AGC Slow - I never knew about the limit setting for the AF Output !! (Time to read the manual again).

	Likewise great info on the various Settings & Operating Modes.

	Being a slightly ?exotic call?, does mean in Contests your rarity increases (I am sure that also works for US stations in different ITU Zones - and a lesser extent CQ Zones) - so I 95% of the time have to ?Run? a frequency. Because I almost never do S&P, I do not use the cluster or any other spotting utilities (skimmer, Reverse Beacon Network) - so I can enter the un-assisted section (if there is one)  - However should you operate in ?Run? mode - then you cal really tell when you have been spotted on the cluster systems - as the increase in traffic is exponential. Often too much to cope with. I would normally work a split - something laughable in contest mode.

	Recently I think that the ?smart contesters? are increasingly using the Reverse Beacon Network (or their own skimmers) - with at least 3 stations always calling me within 2 CQ's after QSY-ing. Interestingly a well known German Dx contester - would always wait 10 minutes after I QSY-ed?. and the general melee had calmed down. I do use the RBN network the day prior to the contest - to try and get a feeling of how well my signals are getting out to various parts of the world. Alas Asian/Africa seems to be a little lacking in spotting stations - so it is rather a US/EU centric propogation exercise - but interesting nevertheless. 

	Despite sending at 25 WPM - and I can happily receive at that, it often seems that stations with 1.5KW of power, into some monstrous 4x4x4 12 Element Array ?farm? can only QRS to 32.5 wpm instead of their normal 33 wpm?. Fortunately I do not have to log some of my rather choice comments.

	Many thanks for the most excellent suggestions - this list, as well as the radios it supports continues to amaze and enthral me.

	Regards

"Too much noise" might mean the AGC threshold is low. One way to adjust it is to set it so that AGC does not activate on band noise (of course it's different on different bands/times). I have mine set to 12. I want AGC to do as little as possible except protect my ears.

I agree with Vic - I want minimal AGC action, only kicking in on the
strongest signals to keep the audio level below the ear's attenuation
reflex (see http://n1eu.com/K3NA_rx_audio.pdf )

I have my threshold set at 14 (along with AF Gain at approx 9 o'clock and
RF Gain adjusted so I can just hear band noise).  (btw, you might try
mysettings if you ever experience pileup mush when on the receiving end of
packet pileups).

RF is getting into your equipment.  RF split cores on all leads into your 2820 should solve the problem.

I had a 480 and did not care for the sort of pinched up audio compared to say
the 850. 
I am using a couple of 6 by 9 speakers in enclosures on the K3, one on each
side of the stereo and the sound is just fine. As they say, opinions vary
and have so many variables like speakers, what/how/where you operate,
physical hearing anomalies, etc. that audio reviews are just about useless.

It's even better if you fix the horrible distortion in the sidetone!  It was
so bad that I found it difficult to zero-beat stations by ear.

Using a couple old Radio Shack "Minimus"
speakers, I find the K3s to be the best sounding
and easiest to listen to radio I have ever had.
I agree, the TS-2000 as well as the TS-480, while
an excellent mobile rig, does in fact roll off the
higher frequencies too much for my antique ears.  
This started to happen around the time Kenwood
went to digital demodulation instead of analog
circuitry.

I was on one of the nets the other day using my
K3s and noticed the net control  station was
particularly hard to understand.   I thought my
hearing had gone or maybe I had set some parameter
incorrectly. Then I looked at the panadapter
display.  There was a very pronounced peak in his
audio around 300 hz and practically no energy past
about 800Hz. No distortion, just a widely skewed
audio passband.  It was a boatanchor radio, so
there was something obviously wrong somewhere as
everyone else sounded great.

My gut feel is that the K3s IS an improvement over
the K3 in regard to the recovered audio.

? I am not much of a "poster", but this thread has had my close attention. I guess even though I have been hamming for over 60yrs, I had somehow grown to believe that speakers for voice communication or CW, for that matter, were very NON- critical. In recent years I have come to a very much DIFFERENT opinion.
? For close to 10yrs my 2m SSB rig was an Icom 746Pro. I loved the audio out of that rig. It had a 2m SSB only TX issue that Icom could not resolve after multiple trips back for repair. I sold it and bought a Kenwood TS2000. Swapped the rigs out and was dismayed at how horrible the rec audio sounded out of the 2000. That was with the same Motorola 2way speaker that I had used for years with the 746Pro! I mean horrible! I have quite a collection of the Motorola speakers and trying them one at a time, I found one that I could live with, not quite as good as the Pro but ok. Boy that 2000 was fussy about speakers.
? Fall of 2009 when I added a K3 to the operating position, I found a similar "fussyness", when it came to speaker selection. I was NOT satisfied with the Motorola speaker that I had used happily with a IC-735 for many years. Speaker selection seem "critical" just like the 2000. That coupled with how one sets the Shift/ Width/Hi-Low cut make huge differences in the way the radio sounds (obvious). Huge variability with the Shift/ Width/Hi-Low combined with mode and filter. WE HAVE CONTROL of these variables, they are not predetermined. I can make the K3 unpleasant to listen to with some combinations, no question. 

? Last month a K3s entered the picture and again I was trying about every speaker I had. Trying to find one that sounded as good as the K3 / Motorola speaker combo. None of my Motorola speakers came close. In the end I found a speaker from a failed power speaker system that I had relegated to the garage. I very much like the sound of that speaker and the K3s.
? I use RX equalization AFTER I find a speaker that I can live with. I know that in this time of my life, my ears are not what they were? decades ago. I suspect that not only do I have known losses, but I may have certain frequency ranges that may be ANNOYING as well.
I know back in my HiFi / Stereo days with vacuum tube amplifiers, speaker selection was pretty simple for me. When I transitioned to solid state amps, not so much.? 

To anyone who dislikes the sound of your K3 or K3s, my experience is try LOTs of different speakers. I saw huge differences, not subtle, but HUGE. I'll bet you can find one that will work satisfactorily. These solid state AF amplifiers just may be more fussy about that transducer that is attached than what some of us would expect.

I had a 480 and did not care for the sort of pinched up audio compared to say
the 850. 
I am using a couple of 6 by 9 speakers in enclosures on the K3, one on each
side of the stereo and the sound is just fine. As they say, opinions vary
and have so many variables like speakers, what/how/where you operate,
physical hearing anomalies, etc. that audio reviews are just about useless.

While this is not the only possible cause, it's likely. Other possible 
causes include a bad piece of coax or bad DC wiring.

If the problem is simple overload of the 2820, what is needed is NOT 
simply slipping a split core over the coax from the 2820, but rather 
multiple turns of the coax through a #31 or #43 Fair-Rite core. That 
could be a split core or a toroid. If it's a split core, five turns is a 
good start for 40-10M, one or two more if the problem is from 75M. If 
it's a toroid, I would start with 5 turns for 20-10, 7 turns for 40-15, 
10 turns for 80-20.

Also, think about antenna locations. Are the HF antennas and 2M antennas 
close together? Separating them a bit could help.  And the HF antennas 
should all have a multi-turn coax choke at their feedpoint (that is, up 
in the air).

RF interference is NOT solved by a connection to earth. RF interference 
CAN be solved or reduced by bonding together every piece of gear in the 
shack with short, fat copper. That combination of chassis DOES need a 
bond to all other grounds in the building, both for safety and for 
reduction of hum, buzz, and RFI.

And even though John said he had "checked" all the coax, a bad piece of 
coax (either the cable or the shield connections) should be suspected as 
a possible cause.

Study http://k9yc.com/GroundingAndAudio.pdf for lots of detail on this. 
And study k9yc.com/RFI-Ham.pdf for a tutorial on how RF gets into 
equipment, how ferrite chokes work, and how many turns on which ferrite 
cores to use for different situations.

Yes, this is one of the most common causes of lousy SSB audio. Here's a

I suspect that the frequency response of the Motorola speakers are 
carefully shaped for maximum speech intelligibility in a noisy 
environment, and their response may be peaked a bit in the upper speech 
range. In the years when those loudspeakers were developed, Motorola was 
the premier 2-way radio company on the planet, and full of great engineers.

IMO, the BEST speakers and headphones for ham radio are those which have 
FLAT response (that is, equal at all frequencies) within the speech 
range (100 - 5,000 Hz) and low distortion. If they have wider response 
(like hi-fi speakers), that's still good. And if their low frequency 
response is rolled off, that's even better!

I would adjust RXEQ WHILE choosing an external speaker, tweaking 
settings for each one as you try it. If, for example, peaky response of 
a particular loudspeaker bothers you but it's a good quality (low 
distortion) loudspeaker, RXEQ can be used to reduce that peak to make 
your ear/brain happy.

two more cents - are we rich, yet?

Couple more comments on K3 audio quality and etc.

The MOT metal mobile speakers were designed for FM mobile and did 
sound good.  I don't have any so have not tried marrying one to a 
K3.  SSB sounds different than FM, especially full quieted FM. 
Installed a lot of Micors, Mitrek, Syntors, etc.

I did note the difference in sound when I went from the old FT-847 to 
the K3.  Did take a little time to adjust to "its" sound.
I have made a couple adjustments in the AGC attack with subtle 
changes in the sound.  But boy did it hear better on HF!

The full spectrum response of the SONY MDR-V600 stereo headset is nicest.

I often run bw down to as low as 2.1 KHz on SSB  (2.8-KHz filter) and 
that reduces white noise level.  SNR is directly proportional to 
bw.  So that improves the SNR.  Of course in a crowded band it also 
reduces QRM.  HF QRM is not so bad here as it must be in civilized 
areas.  Year's ago I ran off the grid on batteries and had S0 noise 
floor on 75m phone using a TS-180S and dipole.  I could really hear 
the weak one's.  Now its more likely S5 noise floor (different radio 
- different s-meter - on the grid!).

Not sure upgrading my K3 audio board would make enough difference for 
me.  Any guess on cost and difficulty of installation?  I have yet to 
install my new synth boards - too busy building 2m amplifiers.  It 
will be interesting to see what difference that will make.

I think audio quality is too personal to provide universal 
solution.  In the old day's choosing a stereo or speakers, I would go 
to an up-scale shop in Hollywood or Beverly Hills to chose the 
equipment as they had lavish sound rooms - then head back to West LA 
discount stores to buy one.  I found JBL were the best to my ears.

I've found "Pyle 3" Mini Cube" speakers excellent for the K3.  Not
only are they small (about 3 5/8" x 3 5/8" x 4 1/2") their response
is noticeably rolled off below 100 Hz - and, I suspect somewhat below
200 Hz.  These "front facing" speakers are a treat with the K3 and
most other rigs I've had a chance to try them with ... and they even
manage to make the "flat to zero Hz" ESSB fools sound reasonable.

MCU 2.38
POWER OUT NOW 15 WATTS MAX, 80-20 M: On 80-20 meters, the PWR control can
now be set as high as 15 W (max is still 12 W on other bands). Supply
voltage must be over 12.8 V on key-down as indicated by the KX3?s voltage
display (tap DISP, rotate VFO B). Note: The KX3 will automatically reduce
power as required if current, SWR, or temperature is excessive, or if
supply voltage is too low. If a band other than 80-20 m is selected, power
output will be cut back to 12 W max. It must then be manually set above 12
W after switching to 80-20 m.

Odds are it's the Voltage: this is what I usually run into.

I so agree.

What I use are a pair of speakers with a truly flat response all the 
way from 80 Hz to 22 KHz but extreme overkill...: Mackie HR824 
powered Studio monitors. They are perfect to me and extremely flat. I 
already owned them because I used to do recording. In this vein, if 
you can find a cheap studio monitor on fleabay or wherever, you will 
surely love it with your K3s/K3.

None. Transmitting into a high SWR (such as no antenna connected) will
result in the power amplifier shutting down to protect itself as long as the
condition exists. 

Hook up an antenna or dummy load. You should see full power output.

Elecraft has gone to great lengths to protect all of their rigs from such
events.

Being a knucklehead, I tried transmitting briefly with RMS Express, and
forget to connect my antenna to the KX3. Transmit power was set to 15W. I
have the internal tuner installed. What's the likelihood that damage may
have resulted?

Yes, excellent AF response, very nice for recording, but massive 
overkill. I have a pair as well. BUT -- they are also RFI dogs. Keying a 
5W 2M talkie across the room will cause their woofers to move enough 
that you'll clearly see it, and they're also susceptible at some HF 
frequencies.

The CM500 is fine for communication use, but maybe not for music. When my Grado SR60 headphones died after fifteen years, I tried using the CM500?s for a while. That didn?t work. I stopped listening until I got a new pair of Grado headphones. I upgraded to the SR225e.

Robert,

Yes, those two mods are old, and apply only to the A level boards (below 
SN 3000).
There have been improvements in the K2 sidetone incorporated into the B 
level boards, and are also included with the A to B mod kit.
The changes added a 47k resistor in series with C24 (R11 for the B level 
boards) and a shielded 82mH inductor across pins 7 and 10 of RP5.
The sidetone is still not a pure sine wave, but it is close if your 
sidetone pitch is between 500 and 700 Hz.

Those old mods would be applicable to unmodified A level boards but 
re-design of the circuits would be required for the B level boards and A 
level boards already modified with the A to B upgrade kit.

Don W3FPR

This has been an interesting thread to which I have experimented a bit more
and found the AGC setting recommendations from a couple of posters to be
very valuable, and Eric's suggestions on BW settings to be a nice compliment
to play with. Although, my ears still like a little HF, I like the sound of
a BW from 100hz to 2.7khz for SSB and usually the 500hz filter set to 300hz
with DSP. I now have AGC THR set to max and AGC SLP set to 0. I also set RX
EQ to flat and use hi/lo cut when needed. Really cuts down on the high
frequency hash I get from this qth. I leave the AGC settings the same for
SSB and CW and play with BW and cut between the two modes, depending on
conditions. 

I've never ever put any stock into any manufacturers built in speakers. They
are there cause they have to be :) For the K3S I use a combination of a pair
of Polk Audio 5 1/4" book shelf speakers (60hz-24kz) and Pyle Pro 3" mini
cube speakers (90hz -18khz), per channel, and the sound is crisp and clear
audio. And, both speaker sets are black to match the K3S and all together
for all 4 speakers cost was $75.00 and change. 

The AGC settings were a big game changer to these old ears.

Gene (and all),

Yes, the AGC settings do help a lot.  The K3/K3S has enough gain that 
often the AGC is activated on the atmospheric noise in the band.
However, I think your chosen AGC settings are a bit extreme for general 
use, but if your ears tell you it is good for you, then keep those 
settings and the rest of this post is for any others interested.

I would encourage first turning the preamp off to minimize the band 
noise - of course the need for a preamp or not will be band dependent.  
I see little use for the preamp on 160, 80, 60, 40 and 30 meters, and 
with the K3, the preamp on 20 meters is "iffy".  You may want to use the 
attenuator on 160 and 80 meters, and maybe even 60 meters.  Use your 
ears, and the band noise will vary from location to location.  Since 
those settings are per band, once you determine the proper preamp and 
attenuator settings for each band, they will be set the same way when 
returning to that band.

So the preamp and attenuator settings are the first order of business.
After that, attack the AGC Threshold and Slope using the information at 
my website www.w3fpr.com "noisy K3" article as a guide.

Finally, use the RX EQ settings to roll off the higher frequencies - 
again, trust your ears - what is helpful for one may not work for anyone 
else.  The K3/K3S has a lot of things that can be customized to the 
individual user.  It is usable 'right out of the box', but can (and 
should be) customized for your individual preferences.

I agree completely with several other comments that the best speakers 
and headphones are those which give a flat response.  Flat response 
"Hi-Fi" speakers and headphones work quite well.  Use the controls in 
the K3/K3S (mainly RX EQ) to tailor the sound.  If you use speakers that 
have peaks and adjust the RX EQ to those peaky speakers, when you use 
headphones, the RX EQ will be wrong for them.  By using flat response 
speakers and headphones, you should enjoy the same response from the 
speakers and the headphones.

Great advice.  Mine, from one who has done this unsuccessfully, and then 
with advice, done it successfully, GO SLOW.  This means small changes to 
one parameter and some listening time before another change.  The 
changes to the various AGC parameters will have subtle effects, not all 
of which will be apparent on the first signal you listen to.  The K3 is 
incredibly configurable with multiple parameters, and the number of 
combinations is huge.  You need to creep up on it.

The right combo for you may differ between SSB and CW.  Try 75 [above 
3800] at night ... it's crowded and probably somewhat noisy [you can 
ignore most of the content, just go for the sound of the signal :-))]. 
On CW, I found DX pileups and pretended I was the DX tuning around the pile.

I had pretty much given up on the AGC as too complex and was going with 
the stock, out-of-the-box settings until I got this advice.  You can 
start with the stock settings or someone who believes they've achieved 
nirvana, but yours will depend on you.  Nobody hears the same you do and 
only you will know.  Just go slow and you'll find your sweet spot, I did.

It isn't so much that the K3/K3S has "gain", but that the factory
default AGC THReshold is so very, very low. Measurements by KE7X [1]
have shown that the default setting of THR=5 corresponds to an AGC onset
at less than S3, whereas competing rigs have a threshold of S7 or even
higher. This very low AGC threshold is what allows the AGC to be
activated by band noise.

Elecraft's factory defaults of THR=5 and SLP=12 compress all signals
above the AGC threshold into a very narrow range of audio output levels
[see the measurements by KE7X]. This makes for comfortable
broadcast-style listening - but there is price to be paid. The default
settings greatly reduce the differences in the *true* strengths of
incoming signals - important differences that DXers and contesters
*need* to hear, in order to pick individual signals out of a pileup.

Following complaints from DXers, DXpeditioners and contesters about this
so-called "pileup mush", and following further series of measurements by
KE7X, Elecraft eventually did increase the available range of AGC
THReshold settings (the v4.51 firmware upgrade). 

Following the release of FW v4.51, consensus within the [K3-contesting]
Yahoo group about the most important settings for DXing and contesting
has been as follows. 

* AGC THR: increase to at least 8 (from default = 5) and preferably to
12 or even 14 if your ears can handle the increased range of audio
levels [2].

* AGC SLP: decrease to 8 or even less (from default = 12). Lower SLP
settings allow stronger signals to sound somewhat louder, and thus more
realistic, but the range of variation will be partly determined by the
THR setting already made; so always experiment with THR first, and with
SLP afterwards. 

* AGC DCY = SOFT (not default=NOR). The User Manual claims that "The
SOFT setting can reduce IMD caused by traditional AGC, and is especially
useful in 'pileup' conditions, in some cases making it unnecessary to
turn AGC off."
 
The settings recommended above have essentially solved the problem of
"pileup mush" for those who have tried them... but regrettably, Elecraft
has done almost nothing to make DXers and contesters  aware that such
changes are possible. 
 
More than 3 years after the firmware release notes boasted that v4.51
"greatly improves signal clarity in pile-ups and other high-noise or
dense-signal situations, especially with threshold set to 12 or higher",
that information is *still* missing from the User Manual. There is also
no information on how to create different 'profiles' of AGC settings for
different types of users.

Meanwhile, Elecraft's factory AGC defaults remain exactly as they were,
still optimized apparently for comfortable 'listening', while many DXers
and contesters remain unaware that their K3/K3S could actually be *so*
much better. 



[1] http://www.ke7x.com/home/miscellaneous-k3-information

[2] It is important to give any increased AGC THReshold setting an
extended trial. To anyone accustomed to an artificially restricted range
of audio signal levels, a higher setting will initially sound quite
'aggressive' -even though the new setting is much closer to real life.

Subject: [Elecraft] K2 encoder kit 4 pin connector
Message-ID: <1458745704430-7615471.post@n2.nabble.com>

Hi all,
Just finished the front panel on my 2nd K2 last night and in the process of
building the encoder daughter board, I noticed there was an unused 4pin
connecter supplied in the kit. Long story short, I ended up ruining the
connector, but I don't see that it's actually used for anything. 

I don't recall anything like this needed on my first K2 either that wasn't
already supplied in the other kits. 

Is this needed elsewhere later on or what is this part for?

Tnx es 73,
LS

It's not a question of whether "your ears can handle the increased range of
audio levels."

I've been in the trenches battling against pileup mush since the K3's
release.  This is only one guy's opinion, but there's another important
prerequisite that's been missing from this discussion.  And that's to use
highly isolating headphones.  That is the ONLY effective way of presenting
the required wide audio dynamic range to your ears.  Unless that's in the
picture, you're significantly handicapped from vanquishing pileup mush.

The use of highly isolating headphones is what allows you to use lower
levels of RF Gain and still clearly hear the weakest signals.  And only
then will the strongest signal levels be below the ear's attenuation reflex
level

K3NA wrote the book on this 8 or so years ago.

I don't dispute what Barry says below, except that IMO it is a question
of *both* re-profiling the AGC settings within the K3/K3S *and then*
doing whatever else is necessary to present that enhanced range of audio
levels to one's ears.

Neither of those actions can deliver its full benefit without attention
to the other one as well.

FWIW,
I once heard a friend transmitting with a rig that was in swr foldback 
condition due to his antenna. Each syllable started at full power and 
clamped down. (My terminology)  It was a strange sound.  I had never 
given it much thought but expected there might be some delay built in 
somehow to keep it clamped down for the start of the next syllable and 
so on.  I wonder if such a thing exists?

LS,

Yes, that 4 pin connector is extra - use it for whatever purpose you want.

There is a situation with the new encoder in that its board can contact 
the back of the control board.  That is not completely clear in the manual.
The area of the Control Board that could possibly contact the encoder 
board must have the pins flush cut and the back of the encoder board 
must also be flush cut.
In addition, a bit more space can be obtained by mounting the standoffs 
on the back of the Front Panel board so the lockwashers are between the 
board and the standoff instead of under the screwhead.
Make certain the two rubber bumpers are in place on the top of the Front 
Panel board so they will contact the 2D connectors.

Regarding headphones/speakers, the way I learnt it many years ago was that
hi-fidelity transducers were generally a no-no in communications, primarily
because frequency response and other distortions (if done correctly) aided
in hearing desired signals. 
Of course, back then our receivers weren't even in the same ballpark as
today's, with their audio processing/filtering capabilities and so forth, so
I suppose it was more common to seek help by introducing distortions in the
transducers themselves, like peaks in the frequency response that helped
shape the signals. 

That said, I do use my "hifi" headphones with my K's; I haven't tried my
aviation headset yet though. I'm tempted to give that a go soon as I can
retrieve it from the hangar.

But I wonder if hi-fi speakers and headphones aren't still being too
faithful to what's actually going into them electrically? Even on
top-of-the-line rigs like ours?

Hi Don, 
Ok thanks for the info. Whew, that's good because I managed to ruin it
anyway having made a mistake with it that I'm too ashamed to admit to on the
reflector hi hi.

And thanks for the warning about flush-cutting the daughter board. In fact,
I did find some discussion of this in the archives so I went over mine with
my flush cutters last night and got all the nubs as close as possible to the
board. The manual describes putting the lock washer under the standoff also
- maybe this was a change in the new manual? In any case, I checked the
clearance with a straightedge over the two standoffs this am too and it's
veeeery close hi hi. So I'll be careful with this at assembly once I get to
that point.

I don't remember this on my first K2 which is #6882 I think. Maybe it had a
different encoder? I'm too lazy to take it apart to look hi hi.

On to the RF board now. I'd forgotten what fun this kit is to build!

Subject: [Elecraft] Change in P3 Offset macro...
Message-ID: <1458750679.13613.20.camel@nk7z.net>

Hi,
For those that are using the P3 offset macro available at:

http://nk7z.net/adding-an-external-keypad-to-the-k3/

or

http://nk7z.net/wp-content/uploads/2016/02/CP48-Master-Spreadsheet.xls

if you download the spread sheet directly, ?I have made a small
modification to reduce the size of the transmit marker on the P3
display window. ?The new macro is:

BW0001;SWT13;SWT13;FT1;UPB7;RT0;XT0;#SPN000060;#RCF+002500;BW0280;

Basically, the macro sets bandwidth to as small as possible, then
transfers that into B, initiates the split +5, and then resets the
bandwidth to 2.8 KHz. ?This results in a nice narrow red line, that you
can move around, while listening to your DX station. ?It no longer
fills the screen with whatever bandwidth you had set prior to calling
this macro. ?

It will work either via the Genovation, or directly in the P3 if you
hand type it in, and assign it to a button...
?

Won't argue with the experts.

However, I really wonder why one would not want a "brick wall" type 
earphone/speaker which greatly rejected anything outside the audio range 
of interest.  There is the issue of dynamics (e.g. 100 wpm CW) which 
probably needs some higher frequency response.

In the early 60's I had a set of high impedance earphones that had a 
mechanical resonance at about 400 Hz.  It was great for CW.  Zero 
beating was easy too.

The selectivity of RX's in those days wasn't much-- except if you were 
lucky to have a Q-multiplier.  The resonant earphones were welcome.

Actually, I just checked mine after finishing the flush cutting and the
boards are going to touch when they're screwed together. 

In the archives it was suggested to use electrical tape, but I'm thinking a
more durable solution might be a thin layer of resin on the daughterboard as
a more permanently attached insulator. Any thoughts?

I'd like to thank everyone who took the time to respond to my posting about
just buying my new KX3 (first radio purchased since 1980) and answering some
of my questions I had and providing suggestions and feedback. Much
appreciated.

I have to say this KX3 is amazing and I'm very happy that I made this
purchase. I spoke with Elecraft just the other day with a few questions and
Craig there was great just as he was answering questions last month before I
ordered my KX3.

Again, thanks!

Tom / W1PDI

Resin would be difficult to remove should the need arise.

How about a thin piece of cork, often used in crafts?

Well I think Rick's idea of cork is the way to go, though maybe it wont be as
glamorous as fish paper! hi hi. And it'll stay put sandwiched between the
boards too, I imagine...

Onwards to the RF board portion starting tonight. This part I remember well
on my first K2, the parts inventory alone takes most of the evening :).

Yes, my first RX when I was a child in the 70's was a Realistic from Radio
Shack. I can't remember the model but it was as wide as the Red Sea,
especially with the built-in speaker. At one point I got a set of comm
headphones with a hefty peak in 400hz or so range and it really worked well
as a "poor man's" audio filter. That was back in the days when novices could
only use CW so it didn't have to sound good on AM sigs (and it didn't), just
good on CW tones. It really helped a bunch - I wish I still had them!

Yes, and Elecraft's tend to multiply once you get your first one. I started

The TF3MA sidetone mod is still current as it is in fact a modification of
the B level board, not just the A level board, as the site states that this
is an improvement of exactly the 47k / 82 mH A to B improvement mentioned in
the quote below. See
http://www.raunvis.hi.is/~matti/TF3MA/sidetone_tf3ma.html

See also my mod list here:
http://la3za.blogspot.no/p/la3za-unofficial-guide-to-elecraft-k2_28.html
(search for sidetone), where I specify it as : "Even more sinusoidal tone
than the mod in serial #3000+ gives"

I would try a piece of heavy-duty mylar packing tape stuck to one board. 

Optionally a thin piece of plastic, such as we must deal with encasing so
many things we buy these days or even a thin sheet of cardboard, held in
place with a bit of double-sided tape should be more than enough.

Resin would be difficult to remove should the need arise.

How about a thin piece of cork, often used in crafts?

Don I beg to differ.  From LA3ZA's K2 mod site:

########################################
Sidetone mod 
Updated Nov 2006
	
Even more sinusoidal tone than the mod in serial #3000+ gives	

Important to have an inductor with correct series resistance (KT5X)	

Simple, one more capacitor
		
TF3MA
############################################

I installed this mod in my S/N 4119 and it made a huge difference in
sidetone quality.  The original design had so much harmonic content that it
was difficult to zero beat stations by ear.

Back in the 50's and 60's there were many articles in the mags of hams
mounting a headphone in one end of a tube. The length of the tube was cut to
provide resonance at the desired audio frequency. Such filters actually
provided pretty sharp responses for CW operation for Hams with slender
wallets (like mine).

Yes, my first RX when I was a child in the 70's was a Realistic from Radio
Shack. I can't remember the model but it was as wide as the Red Sea,
especially with the built-in speaker. At one point I got a set of comm
headphones with a hefty peak in 400hz or so range and it really worked well
as a "poor man's" audio filter. That was back in the days when novices could
only use CW so it didn't have to sound good on AM sigs (and it didn't), just
good on CW tones. It really helped a bunch - I wish I still had them!

Sverre.

I beg to differ slightly.  The B level boards already have the 82mH 
inductor across the same R-PAK that the TF3MA mod wants to install the 
large capacitor.  In addition, the 47k resistor is already in place, but 
the path must be broken to install his 47mH inductor.

While it is do-able on the B level board, it is not as straightforward 
as for the A level board.  To follow the TF3MA instructions as written, 
one must have the A level board.  With the B level, the existing design 
must be modified and the mod re-designed a bit.
For circuit savvy K2 owners who understand how to follow a schematic, it 
should not be a problem, but those lacking that ability should proceed 
with caution and the help of someone who can interpret the schematic.

OK, Don - no problem with that :-)So the effect is most striking and easiest
to do on the old A level board, but it is doable and has a positive effect
even on the B level (i.e. the present) K2 board as Bill W4ZV testified to in
his response in this thread also.

An obscure Novice in SoCal did that ... he had no wallet.  PVC pipe 
hadn't been invented, he used a mailing tube, same tube he made a 
telescope out of with a shaving mirror.  He actually had to study some 
of the simpler math associated with acoustic resonance which was of some 
assistance starting college later in life.

Don't ever think Amateur Radio isn't a great training ground for teenagers.

Hi Wayne,
Is there an ?official? channel for firmware feature requests? I?d really love to see an easy way to adjust NR mix without having to disable/reenable it or to go through the menus. It would be nice to be able to tweak it while tuning around the bands. The other thing I?d like to do is to be able to disable or lock the RF gain control (i.e. put it on 0db and leave it there to prevent ?accidentally? changing it and wondering why the band went quiet).

I also need to agree with another poster here that the PX3 is freakin? awesome. Just got mine.

Thanks,
Tim Henrion

Both of the newer Yaesu radios that I have (FTDX-3000 and FT-991) give a way to do this to one degree or another.

Subject: [Elecraft] Strong recommendation: MFJ 18xx-series single-band whips
	for KX3, etc.
Message-ID: <2B29826C-02A4-4428-9A02-37747701C0F1@elecraft.com>

Hi all,

I've been using an MFJ-1820T telescoping 20-meter whip for a few months. Considering its length (48"), results have been excellent. I typically use it with the KX3 on a picnic table at 15 W (with an external battery), or hand-held at 3 to 5 W (internal battery). 

During the ARRL DX contest I worked many countries in CW and RTTY modes, and have also had a number of longer QSOs on 20-meter SSB. Of course at these power levels, with an electrically short whip, good band conditions can't hurt. 

I prefer a 25' or so wire-in-a-tree antenna when there's time. But when I need a quick deployment antenna that weighs very little, I pull out the 1820T. Note that you *must* use at least one counterpose wire. More than one helps, but all of the QSOs I described were made with a single 13'-long wire laid out on the ground. With no ground wire, you'll be down some 15 to 20 dB in transmit mode.

Since the 20-meter results were so good, I also bought the whips for 40, 17, 15, and 10 meters. 40 meters is a rough ride at 48", but I was still able to check into daytime SSB nets all over the west coast running 10 W. On the higher bands, results improve as you go higher in frequency. I worked a few JAs on 15 meter SSB running just 1 watt. 

A traditional problem with such antennas is that the the SWR can sometimes be unexpectedly high, requiring that you micro-adjust the telescoping length and/or adjust the length of the counterpoise wire. This is completely unnecessary if you have an auto-tuner available. In particular, the KX3's ATU can quickly match any of these whips over their full target band. In a pinch the ATU can also match a given whip on adjacent bands. In the DX contest mentioned I tuned up the 20-meter whip on 17 and 15 meters as well, and made a few Q's there, despite the losses due to off-resonance operation.

These whips can handle a surprising amount of power. They're rated to 25 W, but I ran 50 W through the 20-meter version for several minutes without damaging it. Some other compact whips I've tried overheated quickly even at 10 W, including some of the Maldol models. When this happens, the SWR goes up and stays up until the coil cools down. 

Caveat: Always use a full-size antenna when possible. But if you've just crested a new hill and only have a couple of minutes to see if the RF really is greener on the other side, this is an excellent choice.

73,
Wayne

Funny you should say that. I have only had my KX3 a week and I'm already looking at and reading about the K3S. I better get a hold of myself - at least until I get back from Dayton in May.

Wayne,

Funny you should bring this up, I just received an MFJ-1899T today. Slapped
a counterpoise on it and at 6 watts running JT9 (in New Jersey) was able to
be heard (watching PSK Reporter) all the way in CA and Alberta.  Just
worked a station in MN.

I'm not even giving the whip a fair chance... I'm sitting in a basement
with it cranked up to the floor joist over my head, nestled between 4 foot
fluorescent tubes and metal duct work. It tuned 1.2:1... counterpoise is
connected to ground thumb screw next to antenna jack.

I did groove a small piece of 2x4 for the right angle BNC connector to be
cradled on so all that weight of the telescopic whip doesn't damage the
jack...

Can't wait to take this down to the shore in a few weeks and see what it
can really do without all the disadvantages I've placed on it tonight....
:-)

Tom, W2YF

I got the whip for 17m. I figure there is not much difference between a coil at the base of the whip and a coil inside the ATU. Neither one will radiate. So get a whip for the highest band you want to use and let the ATU provide loading for lower bands.

That is not my experience. A high-Q loading coil, combined with the whip, is resonant near a given band and provides much lower loss than a whip of the same length with no coil, matched using the internal ATU. So while the ATU *can* match the whip on bands other than the design band, the farther you get from the design band, the greater the loss. 

That said, a 17-meter whip is a good choice if you want to occasionally use it on 20 and 15 meters and you're willing to accept the comopromise. I'll try to put some numbers this. I have whips for all three bands for comparison. 

When I operate mobile I use a 17-meter whip for this reason. A mobile whip with a larger tunable coil would work much better outside the design band, but my XYL (when she's riding in my CRV) prefers the svelte look of that skinny, single-band radiator :)

I'm glad my XYL is happy with the Little Tarheel antenna on the 
4Runner. My high point with it was driving over I40 from Barstow 
and contacting 5Q4B in Denmark on 15M SSB. It was a good day and 
he was working stations all over North and South America. DX at 
100 KPH. (She was driving.)

Getting the k3 to "talk" to the software is proving a tad difficult. (read, I'm slow?)

Subject: [Elecraft] Delayed Options
Message-ID: <1458808293504-7615506.post@n2.nabble.com>

I'm considering the purchase of a KX3. I'd like to delay the purchase of
certain options in order to smooth my cash flow. Would it be especially
difficult if either of the following options were delayed:

 * KXFL3 Dual-Passband Roofing Filter
 * KXAT3 Internal 20-W Automatic Antenna Tuner

I realize that my question could be considered a FAQ. But, as far as I can
tell, no one has asked my question in exactly the same context. So it seems
to me not a FAQ, though we might agree that it's a near miss. If I'm wrong
and my question /is/ a FAQ I'd appreciate a pointer to one or more of the
threads I failed to find.

Thanks very much.

Cheers,

The options can easily be added at any time.  You may want to download 
the manuals for the two options and look over the sections on installation.

K3 or K3S?

 > Is there a link for step by step setup for a k3,

No.

AFSK or FSK?

What interface?

You might look at the examples for MixW and MMTTY with microHAM
USB Interface III at www.microHAM-USA.com/support.html (in the
USB Interface III area).  While they are not Elecraft specific
they should get you started in configuring the software.

Note - for AFSK and PSK31, use AFSK A and DATA A respectively.
Set MENU:MIC SEL to "LInE In", connect sound card audio to the
LINE IN jack of the K3 and adjust the mic gain for *four bars*
of ALC (ALC may flicker to the fifth bar).  *DO NOT* adjust power
output by adjusting the mic gain - reduce power in PSK31/63/125
to ~40 watts maximum using the PWR control.

73,

It would actually be nice to be able to lock out any arbitrary control.
I keep accidentally adjusting MIC gain.  Be nice to turn off the ability
to adjust it in the menu until I want to do so more deliberately than
the "random tweaks" I keep giving it :)

Hello All,

Please excuse the amateurishness of this question, but could you get one
of these whips for a low band such as 40M and use it on say 20M if you
don't extend it fully?

Most of the electrical length of these physically-short whips is in the
loading coal. Adjusting the length of the 40m whip as you describe would
only move the resonance point around within the 40m band. To move the
resonance point between bands, you'd need to tap the coil. MFJ makes such a
whip; scroll to page 2 of this doc and read about the 1899T:

You can, but the better compromise if you can do it is the longest possible
radiating element with the least amount of added inductance in the coil.

Reason being, a very short radiating element, even when tuned to resonance
with a lot of coil will have, among other things, a very low radiation
resistance. In the field this will have two results that will make you tear
your hair out: one, an extremely narrow bandwidth, which will make
adjustments to resonance extremely touchy and two a high swr even at
resonance. So you may still only be able to get it to 2:1 at resonance,
depending on how short your element actually is. And even so, the
performance will be significantly reduced due to the low radiation
resistance.

I do a lot of /p with my Buddipole and have found this through
experimentation. For example, with its stock 5 1/2' whips, it's only
enjoyable to deploy on 10,12 and 15. On 17 and 20, it gets really touchy to
adjust and the 2:1 bandwidth just barely covers the CW portion once tuned.
Also, raising the antenna on my 19' mast raises the resonance enough to
really be annoying to get it setup on 20 meters.

30 and 40 meters, forget it lol....

So I ordered the longer 9' whips for mine and that all but solves the
problem. on 20 meters, for example, only a few turns of each coil is needed,
but the SWR at resonance is commonly 1.2:1 or even 1:1 depending on where I
deploy out in the woods. It's reasonable to tune on 30 meters (and haven't
tried 40 yet). On 10, 12, 15 it can go to full length and no coils are
required at all. There the bandwidth is very wide with a low SWR across
almost the entire 15 meter band for example.

When I really need to "boom in" somewhere with my 10 watts, I setup a
resonant antenna with the long whips and just accept having to adjust the
antenna when I change bands.

When I'm lazy, I just use a 100' wire inverted V centered on my 19' mast and
just use the tuners in my rigs (all my K's have the antenna tuners in them).
That works pretty good, especially on the higher bands, but not quite as
good as resonant setups...

Anyway, just my experience since I operate /p almost 100% of the time now,
out in the mountains here in northern NM. At 10,000' I'm almost a SOTA
operation lol...

Seconded... I have 4 K's now and my efforts to convince myself to sell this
or that one to pay for that or this one have failed. Even my K3, which is
now "officially" an orphan and the main candidate for selling, is of course
still fully supported by Elecraft and probably will be forever. So somehow
the new synthesizer upgraded jumped into the radio and I use it on my /p
trips all the time now. I can't seem to get rid of it.

And a 2nd K2 is slowly coalescing together on my bench right now.... 

I just can't seem to stop it all! hi hi.

As for the K3S, if you had to have only one rig from here on out, that would
be the one to have. I haven't used mine too much yet but it would be the one
for digital modes and a panadapter, due to the USB port and its built-in
devices for computer operation. 

Mine may end up, though, doing the same duty as all my rigs (/p with a
battery and a key), judging by my progress on my home station.... 

And then you have the reflector, with Don and of course the Elecraft royalty
themselves posting here, all of whom are just a bottomless pit of detailed
information about your rigs no matter how arcane your questions may be....

So buyer beware hi hi!

Curious about something, if I may ask a personal question.  As others on
the reflector have said, buying Elecraft kits can be habit-forming. I have
the K3, KPA500, KAT500, P3, KX3, PX3, KXPA100, K2/100, KPA100, every
accessory for every one of them, and a handful of the mini kits (noise
generator, balun, power meter, etc.)  Last week I ordered a K1; it should
be here tomorrow.  I haven?t the slightest idea what I?m going to do with
it after I build it.

I so enjoyed building the K2 that I am seriously thinking about buying
another, as you did.  But I don?t know what I would do with that either.
And so, just wondering about your doing the same . . .

Is there a support group somewhere that we can all go to, forthrightly to
confess our addiction?  Or is that actually what the reflector is for . .
. finding forgiveness in the resonance with others. . . ?

I had that addiction.  I was doomed, on my way to continually build every kit offered by Elecraft for the rest of my days.

I was saved by my other hobby of woodworking ? instead of soldering iron in my hand, I hold a hand-plane.  Instead of exotic components, I work with exotic woods.  Instead of resulting with a radio sitting on the shelf collecting dust, I have furniture that collects dust.

Can anyone tell me if the new KSYN3A boards are less prone to birdies than the old ones? I'm having a small problem with birdies in my K3, and have lessened them quite a bit with careful routing of cables, grounds, etc. I do know that they can be nulled out, but I would like to get rid of them more "at the source."

Ted et al,

The first step is understanding you have no addiction.

The second step is acknowledging your have a dedicated avocation.

You could be forever buying non-working lottery tickets with what you 
spend but instead you are wisely constructing something tangible that 
is useful and with that dedication, you're making quality items from 
quality materials and assembled in a Quality Controlled environment. 

So here's an idea for what you can do with what otherwise would be 
superfluous by duplication, Elecraft equipment: Contact your local 
ham club, do you have an auction or better yet, a hamfest? No? Is 
there one local enough, that would do. Now go and talk to the powers 
that be and offer your time and assembly skills with them buying the 
kit in mind and raffling it off. If it flies as it likely will, they 
may want to do the same again the following year. And then you get to 
build for free.

Win Win & Easy Peasy

Cheers & 73,

Gary

My suggestion would be to do the following:-

   - Buy the kit instead of the factory assembled unit to save a few $$.
   This will also make you completely comfortable opening it up and adding
   stuff later. It is a very easy build, IIRC I built mine in two evenings.
   That included the internal battery charger and ATU.
   - Add the ATU asap, it is massively useful mobile or even if you don't
   have options for perfect antennas.
   - SKIP the previous advice if you are EXCLUSIVELY going to use something
   like the AlexLoop. You want to bypass the ATU with that kind of tunable
   antenna, so the ATU is only useful for non-well-designed loops.
   - Add the internal battery charger, it makes quick portable operation so
   very, very easy.
   - Add the roofing filter when you feel it would help. I have not done
   this yet, but it probably won't take more than 15 minutes when I do.

Hope that helps. The kits save some cash and give you a nice little "oldish
school" build it yourself project that is missing from so many Hams now.

+1 

From my perspective, having AF gain and RF gain on the same control, with a push that toggles between the two, invariably results in tweaking the wrong one and then having to troubleshoot the issue after the fact.

I?m fine with being able to lock settings, as I rarely find I need to tweak RF gain. Others may have different opinions. Personally as I search the bands, there are generally three knob-related things that I?d like to be able to tweak in real-time with independent knobs:

- Frequency - I really like that the KX3 has ?coarse? and ?fine? adjustment available by default on different knobs (without having to toggle a ?FAST? switch). This is one major ?Nice job Elecraft!? usability item that sets the KX3 apart from every other radio I own.
- AF gain - I guess I use this as sort of a ?Manual AGC?, where others use RF gain.
- NR mix - I pretty much run with NR on all the time unless I am chasing something ultra weak. The setting of NR mix can mean the difference between catching and missing weak signals, so I?d like to see this tweakable in real time.

The #2 thing I love about Elecraft (after my awesome KX3) is the fact that you can ask questions and the guys that actually design and implement the hardware respond. #1 & #2 pretty much seal the deal that my next radio purchase(s) will be Elecraft. Even when I go to my local Ham Radio Outlet and talk to the staff about radios, one guy there pretty much talks about his K3 over anything else. Its funny to hear an HRO guy talk about a radio that HRO doesn?t even sell? :-)

Hi LS,

You may want to try an ATU. In that case, all you need to do is roughly peak the coil tap in RX mode, then let the ATU match the antenna across a full band for TX purposes. I do this all the time, with excellent results, at least with the ATUs in the K3/KX3/etc.

John,

Just like Bruce said regarding the 1899...

I started at one tap position for 20M and then changed the coil tap to
another for 40M. When I wrote my original note that was my 40M testing... I
failed to mention in my earlier email. In this case the whip length itself
isn't adjusted, just the tap, and I guess to be optimal the length of
counterpoise should be as well, but I cut corners and didn't do that.

I got lazy and after getting it close enough I switched on the ATU of the
KX3 and it tuned to 1.2:1. That ATU is a great feature for use with
antennas such as these where bandwidth is going to be narrow and tuning can
be a pain without a good ATU. Cannot imagine life without one when doing
portable stuff with compromised antennas... I'd spend all day tuning up...

Tom, W2YF

I purchased a KX3 assembled with the Roofing Filters, Battery Charger, ATU and hand Mic. I went with having Elecraft assemble it because I wanted the radio to work out of the box.

Here?s what I would have done if I had needed to save some cash:

1) I would have skipped the hand mic - headset is the way to go.
2) I would have skipped the Battery Charger - Had I known that the charger had to be manually enabled every time (i.e. its not always ?trickle charging?) and that you had to ?guess? for how long it needed to be on, I would have skipped it as I don?t see a whole lot of value in that.
3) I?d delay getting the Roofing Filters. I?m not sure I?m even using them as I?m not a CW operator.

The ATU is awesome and is one place I wouldn?t have tried to save costs.

As Tom Schiller, N6BT, famously noted, EVERYTHING WORKS, sort of. He 
demonstrated this by working all continents loading a lightbulb that he 
fed with coax. Tom is the designer of the excellent Force 12 antennas.

I just did a quick NEC model of a 4 ft vertical with loading coil and a 
single quarter-wave radial laying on the ground, and compared it with a 
quarter-wave vertical (16.7 ft) with the same single radial. The model 
is for poor soil, which is typical of most mountainous QTHs. The 
full-size quarter-wave will be 7.4 dB louder than the shortened one. 
That's equivalent to reducing a 15W signal to 3W. The difference is 
slightly greater over better than average ground. The reduced efficiency 
is due to the greatly reduced radiation resistance of the shortened 
antenna.

Bottom line -- yes, shortened antennas work, sort of, but full-size 
antennas work BETTER. If you can afford the weight of a means to support 
the longer antenna (typically a telescoping fiberglass pole), it's well 
worth it! And if a shorter antenna MUST be used, LONGER antenna, LESS 
coil is better.

Hi Wayne,
Yes, I do that too especially on the low bands like 30 on down. I have
found, though, that with the long 9' whips, the bandwidth and SWR is low
enough on 20 and up that I don't even need to use my tuners, especially
since I'm normally down in the CW portions. On 15 and below the overall
length is long enough to form a full sized dipole without the coils. I can
go around the entire globe on 15 with the Buddipole at my selected /p spots
I've found in my local area. One is outside of town on top of a really high
hill (probably about 7100' above sea level) and another is in a state park
in the Sangre De Christo mountains back behind town. The campground I deploy
at there is around 10,000 feet, so with the Buddipole setup as a full length
dipole, I have no trouble working the world on 10 watts if the bands are
good.

And with the tuners, I can be lazy and use my 100' center-fed random wire in
inverted V for everything. The only band the tuners have to hunt around on
with it is 17 meters and they usually can only get down to about 1.7 SWR
(there's probably a current node at the feed point at 18mhz which I could
probably reduce by tweaking the wire length a little bit). 

But even the tuner in the K2 can handle the wire antenna on all bands with
no trouble. So I always buy tuners for all my K's.... 

Tnx es 73,

I have a birdie in my K3 at about 21.022 mhz that I believe accompanied my
synthesizer upgrade. It's about S1 with no ant and the preamp on - I tried
moving the cabling around inside the rig and it had no effect at all. 

Apart from that, I just have the "zipper" sound when tuning on certain bands
now (on 10 meters on my K3 and my K3S does it on 6 meters), which is known
about and normal. Fades almost completely when I have a resonant antenna on
10M

But the birdie is there and audible when I'm /p where 21mhz is very quiet.
It's not present in my K3S, so no idea what it is...

Message-ID: <F5514CCF-0BEC-4E40-A776-4D3F52D7A573@gmail.com>

I recently got a KX3 and KXPA100.  I have a Cobra UltraLite Kid up in my loft with a 4:1 balun and coax down into the floor below.  I can tune most bands fine (I don?t do 80/160 due to plasma TV noise next door).  However, when I try to tune the KXPA100 at 6m it often hangs in transmit.  Or it stops with two dashes displayed.  If I check the antenna with my RigExpert AA-600, the low end of the band is between 3:1 and 4:1, whereas the upper part goes as low as 1.08 around 53 MHz.  I just went to 50.100MHz and pressed tune the display on the KX3 shows 3.1 and is stuck with the xmit light on until I press tune again.

Has anyone seen this?

Subject: [Elecraft] PX3 BETA Firmware 1.42 Now Available
Message-ID: <1458855841482-7615532.post@n2.nabble.com>

Version 1.42 of PX3 firmware is now available for download from:
ftp://ftp.elecraft.com/PX3/firmware/beta/px3m0142_BETA.zip

To learn how to download and install PX3 BETA firmware, follow these
directions:
http://www.elecraft.com/PX3/px3_beta_release_instructions.htm

This release includes the new #RCF (relative center frequency) command which
was recently added to the P3.  The replay buffer has been removed and in its
place, a new 'scratchpad memory.'  Please refer to the release notes below. 

As with any PX3 BETA release, please email me directly with any bugs,
questions, etc.  My email address is pauls at you know where dot com. 


MCU 1.42 / 03/22/2016

* Adds: keyboard macros can now be executed even when the Text Display is
turned off. 

* Adds: #RCF command: ?Relative Center Frequency? applies an offset to the
center frequency based on the passed argument.  Usage: #RCFsnnnnnn;  Where:
?s? is the sign + or -, nnnnnn is the offset in Hz.  For example, if the PX3
is set to a 30 kHz span and you would like to position the cursor on the
left edge: #RCF+015000;   Using #RCF without any arguments returns the
difference in Hz between the center frequency and the vfo frequency. 

* Fixes/Adds: Removed replay buffer and its controls and in its place added
a ?scratchpad?  to hold temporary text such as call signs, names, etc.  Text
may be added to the scratch pad by first pressing the Insert key.  The
scratchpad is cleared each time it is opened.  To move the scratchpad
contents to the Tx buffer, press Ctrl-Insert.  Pressing Ctrl-H when the
scratchpad is open, displays a help screen.  To exit the scratchpad, press
Esc, Enter or Insert.  You may also press a text macro assigned key which
will execute after exiting the scratchpad.  To embed the scratchpad contents
in a text message, use \s . The scratchpad holds one line of text.  It is
erased after each power cycle. 

* Fixes: USB/LSB passband inversion when using transverters. 

* Fixes: an issue when using the ?|? command (IM) with text message strings
shorter than 10 characters.  The IM character is now correctly interpreted
which should solve the problem of truncated strings. 

* Fixes: Keyboard help screen being overwritten by spectrum trace and grid. 

* Fixes: Full Tx keyboard buffer overflow issue in which buffer could not be
sent with Enter.

Very 73, 

Paul n6hz

Can you toss a capacitive hat on the top of the shorter vertical and see
what difference that makes? I've not figured out how to use the modeling
software yet!

Subject: [Elecraft] P3/SVGA 1.60/1.34 General Release, Now Available
Message-ID: <1458858704253-7615534.post@n2.nabble.com>

P3/SVGA 1.60/1.34 Firmware is now available as a general release.  Please be
sure to download, install and use the latest version of P3 Utility which can
be found here: 
http://www.elecraft.com/software/P3/P3_Utility_Setup_1_16_3_15.exe

Currently our tech writer is in the process of updating the P3/SVGA manual. 
In the meantime, please refer to the release notes which I have also
included below.  The main features of this release are the ability to
include P3 commands in SVGA keyboard macros, new #RCF (relative center
frequency) command, support for the K3S preamp/attenuator stages, as well as
several important bug fixes. 

Very 73, 
Paul n6hz

MCU 01.60 / 3-21-2016

Version 01.60 requires SVGA firmware 01.34 to support all SVGA features.

* P3 commands in keyboard macros: Added support to allow P3 commands to be
embedded in SVGA keyboard macros.  When entering a keyboard macro using a
USB keyboard attached to the P3/SVGA, P3 commands can now be intermixed with
K3 commands by preceding the with the '#' character.  Example: set up a
macro to set the K3 to PSK31, frequency 14.070, P3 span of 100 kHz, fixed
tune enabled:   
	FA00014070000;MD6;DT3;#SPN001000;#FXT1;

* SVGA keyboard macros as function keys: The first 8 SVGA keyboard macros
can now be executed from the 8 front panel function keys.  First, using a
keyboard, program the macro and make sure to save it into one of the first 8
locations (mem 1 - 8).  Then on the P3, press the MENU button and using the
encoder, select the SVGA menu and press the encoder to enter. Then using the
encoder, choose "Macro 1" through "Macro 8",  then press the function key
(short tap or long hold) to map the macro to the function key. 

* Enable/disable TX sensing at the TxMon coupler: Added TxSensEn to TxMon
sub-menu.  This allows enabling/disabling of transmit sensing at the
coupler.  For K3 and K3S users, TxSensEn can be set to "disabled", which
will use the serial connection from the K3 to determine the TX state.
Setting TxSensEn to "enabled" will use forward power sensed at the TxMon
coupler to determine TX state (useful for non-Elecraft radios). 

* New #RCF command: "Relative Center Frequency" applies an offset to the
center frequency based on the passed argument.  Usage: #RCFsnnnnnn;  Where:
's' is the sign + or -, nnnnnn is the offset in Hz.  For example, if the P3
is set to a 30 kHz span and you would like to position the cursor on the
left edge: #RCF+015000;   Using #RCF without any arguments returns the
difference in Hz between the center frequency and the vfo frequency. 

* K3S attenuator support:  The P3 now properly scales the display when the
four-step attenuator in the K3S is enabled.

* SWR meter blanked:  Both the analog and digital SWR displays are now
blanked whenever the transmit power is too low to give a valid reading.

* Serial #DSM command:  The Display Mode (#DSM) command now controls the
Transmit Monitor's power/SWR meter display as well as enabling and disabling
the waterfall window.  #DSM0 = Spectrum display only, #DSM1 = Spectrum +
waterfall, #DSM2 = Spectrum + meters, #DSM3 = Spectrum + waterfall + meters.

* New #FON command:  The display font can now be selected via a serial
command.  #FON0 = 5 x 7 pixels, #FON1 = 7 x 11 pixels, #FON2 = 9 x 14
pixels.

* New #XCV command:  The transceiver type can now be selected via a serial
command.  #XCV00 = "K3", #XCV01 = User-defined, #XCV03 = 455 kHz IF, etc. 
The command uses  the same number order as in the "Xcvr Sel" menu item.

* Transceiver definition bug fix - Exiting:  When exiting the "Xcvr Def"
menu page, if the user-defined transceiver is already selected, it will
reflect the new values inmmediately, rather than having to re-select it.

* Transceiver definition bug fix - IF Invert:  The USER transceiver that is
defined in the "Xcvr Def" menu item may now specify "Not inverted" IF tuning
even if the "K3" control language is selected.

* SVGA resolution / main waterfall bug fix:  The main waterfall height had
been switching to the default value after changing SVGA resolution.

* VFO B cursor = VFO DATA A bug:  The VFO B cursor had been matching the VFO
A cursor in DATA A mode, even when VFO B was in a different mode.

* Bitmap Upload bug:  Fixes a bug in which the waterfall area was omitted
from a bitmap capture when the TXMON meters were visible.  





P3SVGA 01.34 / 3-21-2016

* Center Frequency in Tracking mode:  Fixed an old bug that caused the VFO A
cursor to reset to center of screen when VFO A was tuned after the user had
adjusted the center frequency offset using the CENTER function in tracking
mode.  

* SVGA Keyboard: 
	Added support to allow P3 commands to be embedded in SVGA keyboard 	
macros.  
	Added support so P3 can execute keyboard macros from front panel 		
function keys. 
	Keyboard / USB thumbdrive can be used when not in data display mode. 		
	Cleaned up the text message sending, and use of the IM character '|' for
better 	handling of short text messages.  

* Scratchpad:  Removed "replay buffer" and replaced it with a scratchpad
memory.  To use the Scratchpad memory, press the Insert key.  A one line
window will pop up and allow text to be entered.  Press Enter, Esc or Insert
to exit the scratchpad.  Scratchpad text can be sent by pressing
Ctrl-Insert, or embedded in a text message using \s .  You can also exit 
the scratchpad by pressing a predefined text message key.  This is handy for
inserting a call sign into a preformatted message. 

Example: create a text message that contains:  "\s de wa6hhq ur 5nn k" and
assign it to the F5 key.  Now to quickly respond to a calling station, press
Insert, then enter the call sign of the station, for example N6KR and then
press F5.   The call sign entered in the scratchpad will be entered into the
message and transmitted. 

Message counter adjustable field width:  Message counter now takes an
optional precision value that controls how many digits are converted.  The
existing operation of  \c  in a text message would print the message counter
using all 5 digits.  Now \c can be followed by a number from 1 to 9 which
sets 	the minimum number of digits displayed.  
For example, if the current contents of the message counter is 27,  \c2 
would display 27,  while \c4 would display  0027. 

* Multiple \c in a text message does not increment the counter:  In the past
each time the 	\c was used, the message counter would increment. This has
been fixed so that the message counter only increments after the message is
completed.

* Waterfall: Fixes "color rollover" in the SVGA waterfall which could occur
when the SVGA waterfall bias was increased while viewing very strong
signals. 

* TB for external programs: Fixes a bug in which TB commands were being
swallowed and not forwarded to external programs such as DX Labs 
Winwarbler ?.

Now's a good time to learn. :)  Modeling software like NEC is a great 
way to learn about antennas.

I don't have time to do a model, but almost any top-loading is better 
than bottom loading.  My guess is that ONLY a cap hat won't bring a 4 ft 
vertical to resonance without a loading coil, but depending on how big 
the coil and hat are, it could be as much as 2-3 dB better than the coil 
only.

Have had similar problems.  Putting split ferrite cores on power supply, computer, key, cables solved the problem.  Try lowering your power out to a couple of watts.  If the problem goes away, you have RF getting in somewhere.

Brendon,

A capacity hat can work on bringing the frequency downward, but how much 
depends on the size of the capacity hat and the inductance of the 
loading coil.

If you are not comfortable with modeling software, but have an antenna 
analyzer, you can still experiment.  Try a capacity hat and see how far 
it brings the resonant frequency down.  If it is not far enough, try a 
bigger hat.

The fact that you can lower the resonant frequency does not indicate 
efficiency (it only indicates the ability to properly load the transceiver).
Efficiency and lower SWR are not equal.  A 4 foot radiator is still a 4 
foot radiator and will have full efficiency at about 50 MHz. Using it 
with loading coil and/or top hat on lower frequencies will allow it to 
be used, but will not compare with a full size vertical radiator.

Don W3FPR

Subject: [Elecraft] Delayed Options

I'm considering the purchase of a KX3. I'd like to delay the purchase of
certain options in order to smooth my cash flow. Would it be especially
difficult if either of the following options were delayed:

 * KXFL3 Dual-Passband Roofing Filter
 * KXAT3 Internal 20-W Automatic Antenna Tuner

I realize that my question could be considered a FAQ. But, as far as I can
tell, no one has asked my question in exactly the same context. So it seems
to me not a FAQ, though we might agree that it's a near miss. If I'm wrong
and my question /is/ a FAQ I'd appreciate a pointer to one or more of the
threads I failed to find.

Thanks very much.

Cheers,

Not all 4ft radiators are equal! Top loading vs bottom loading changes the current distribution and raises radiation resistance of the vertical radiator. Top loading can substantially improve efficiency.

I bought my KX3 - as a Kit 

	Battery Charger - I am still 50-50 about if this was a good option
	Roofing filters  - Worth every penny (or $ or OMR)
        CW Key - Quite nice once you get used to it
       
I did not bother with 
        ATU - why ? You only have max 15 Watts - Tune your antenna !!! 
        Mic  - I prefer CW

I have used Koc Chen's cocoaNEC 
<http://www.w7ay.net/site/Applications/cocoaNEC/index.html> for 
antenna modelling. It is quite usable.

Thanks for the Mac pointer and advice. Now to see if I can find enough time
to do some modeling.

I do software stuff and spend a lot of time in the "Console" -- Windows
version of that is just so clunky... shudder -- At least the mac is Unix
like so matches all the servers with run Linux. Don't forget Windows has
been training users on their version of UI for 20 odd years. It may take
more than 5 minutes to figure out Mac or Linux. But neither is too hard to
pick up. In fact, Linux has a "Redmond" mode if you really need it to look
similar.

Jim,

Like I implied in my posting, portable operation is often more about convenience than signal strength. 

Your estimate of around 7 dB sounds reasonable. That's about 1.5 S-units, to use the vernacular. When a band is open, this loss still allows a lot of contacts to be made.

Example: A couple of months ago my son and I were doing a bit of hiking/bird watching at Redwood Shores. While Griffin stalked hooded mergansers with his camera, I quickly set up my KX3 at a picnic table. I attached the whip with a right-angle BNC, along with the 13' counterpoise wire. 20 meter CW was very active with EU contest stations, most of them probably running a KW ("or so"). I called several of them running 5 W, and worked most of them on one call. 

I may have been down 7 dB from a full-size vertical, but I got through nonetheless. And I didn't have to frighten any birds away with my usual weight-tossing wild-west antenna deployment routine.

Sometimes size doesn't matter.

Just a minor point. Raising the counterpoise a foot or more above ground rather than just throwing it on the ground will have the effect of reducing ground losses and getting more signal radiated.  So rather than just toss the counterpoise wire on the ground, it?s a good thing to keep it elevated ? run it from where you have it connected (e.g., table top) out to a bush, a branch, to a fiberglass driveway marker stuck in the ground, whatever?s available.  I carry a piece of small para-cord so I can tie the winder that holds my radial wire off to something.  If you?re inside on a second floor, it may not matter much, but at a typical field site with lousy soil conductivity it can.

A single elevated radial will also cause a very slight distortion in the usual uniform radiation pattern with max response in the direction of the radial.  Two elevated radial wires (at about 180 deg) give you the more usual non-directional pattern.

Yes, any antenna that's deployed beats one that isn't. :)  But a #22 
wire taped to a telescoping fiberglass pole can easily be wedged between 
the seat and the top of a typical picnic table, and another #22 laid on 
the ground. There's a photo on my qrz.com page of me doing exactly that 
from a suburban Chicago park c.a. 2004. You'll recognize the radio.

Hi Paul / N6HZ

I?ve downloaded the beta version 1.42.

And I tried to install the beta version, but the PX3 will become off.

I tried to install the current version, the PX3 does not turn off.

Best regard,

True enough, but the whip, when collapsed, is a lot shorter.

For replacement washers, you might try Digikey.  They carry all sorts of 
goodies.  Also, All Electronics carries a wide variety of washers.

No doubt, and the whip is less weight to carry. That's part of the cost 
of 7+ dB. All of life is a series of compromises, and when we're lucky, 
we get to choose. :) To me, they're all tools in the kit.

But I can testify that from my experience working QRP in major DX 
contests, a few dB can be the difference between making a QSO or not, 
mostly based on the noise level at the other end. And 7+ dB is a LOT.

That's true. But when I'm out hiking, doing quick deployments, I'm willing to accept -7 dB. Band not open enough? Enjoy the scenery.

You can find them at some Ace Hardware stores, but they are nylon so 
they won't match the color of the originals. Unless the particular key 
has historical value, that shouldn't matter.

You'll have to find an Ace that isn't all yuppified trying to compete 
with big box stores. Find an old fashioned hardware store. I buy them 
all the time in our local Ace which we still call Bauman's even though 
it has been Ace for 30+ years. That's the kind of place you're looking for.

Hello Kevin:

You can't have the washers out of my trusty J38 but I have a suggestion. 

I have gotten away with just substituting flat fibre washers in such places.
I realize they don't have the "lip" that keeps the screw centered in the
hole, but in normal use there isn't enough pressure on it to cause the screw
to move, once it's tightened in place. 

Many hardware stores carry them. 

If you really want "original" parts with the centering lip, check out
Vibroplex. They sell parts for every key they ever made! I believe that part
number 8035 on their original Bug is what you need.

Since folks are talking adding a top hat or base loading coil, why 
not just extend the length of the vertical to a full 1/4 
wavelength?  1/4WL = 248/50.1 MHz = 4.95 feet (59, 3/8-inch).

Connect a small alligator clip to a 11-inch piece of hookup wire and 
suspend the wire with a piece of cord to "something", OR uses heavier 
stiff wire that will self-support.

Now you have a resonant 1/4 wave vertical.

OR buy a 5/8 wave base-loaded 2m mobile whip - loads on 50-MHz very 
nicely.  That's an old trick for dual-band 6m/2m use.  Try brands 
like Larsen or Maxrad.

Something I should add that I've done in the past when it comes to 
insulating washers that do not have any significant voltage to them, 
as well as washers used to keep paint intact when a screw is 
tightened, is use plastic milk jug material.

you can easily cut the perimeter with scissors or if you have 
excessive OCD, you can take a pipe with the ID the right size, bevel 
the outside of the end to a point and use it with a block of wood on 
the other side, on the table as a punch, remove the wafer, then drill 
the center hole exactly the right size. Cheap, effective and in your 
fridge, right next to the IPA.

OR buy a 5/8 wave base-loaded 2m mobile whip -
loads on 50-MHz very nicely.  That's an old trick
for dual-band 6m/2m use.  Try brands like Larsen
or Maxrad.

This only works for a 5/8  wave 2 M antenna where
the base inductor (It's NOT a * loading coil)
isn't tapped and grounded at one end.   
In other words, if there is a single connection to
the antenna, this will work.
If there's a ground connection such that the
inductor is tapped up the coil it will not
function on 50 MHz.
The Larson LM series will work, but ones designed
for the Motorola (NMO) base will not. 

73, Charlie k3ICH

* A 5/8 wave antenna presents roughly 50 Ohms
resistive and some level of capacitive (-J)
reactance.
In order to match this impedance, a series
inductor is required to cancel the capacitive
reactance, 
So technically, it is not a "loading" which would
be designed to make up for the fact that an
antenna is too short for a ? wave resonance.

I see you mention a 10 dB increase in levels between band closed and
band open, with the notion that if you don't see that, you have too much
local noise.  That makes a lot of sense for bands like 15m.  I don't
quite follow how one can use that rule of thumb on 6m.  For 80m,
presumably it should be quieter in the day.

I've been looking at various bands with a PX3.  Certainly my outside
(80m dipole ish) antenna is quieter than my attic dipole, but some times
it's pretty close -- presumably that's when band noise dominates.

I wonder if it's possible to have any quantitative norms.  For example,
looking at the waterfall on 30m with a 50 kHz span, and ref of -110 dBm,
I'm seeing a lot of black pixels with a fair number of dark blue.  There
are a few solid lines that are obviously interference.  And I see some
short-duration broadband pulses (horizontal lines).  So I think I have
some issues, while others might find that better than usual.

Clearly some noise sources are obvious on the panadaptor.  But most of
what I'm seeing is not obvious.  In the end I suspect that trying to
decide if I have local noise by making measurements is not going to work
or be all that useful.  (Certainly measuring with power off makes sense,
and the open-vs-closed band levels is something I'll probably try to
really measure.)

Also when using the PX3, I realize that the levels can be interpreted in
two ways.  For signals narrower than the bin size, it seems that one
should read the level as the power in the bin and hence the signal.  But
for broad noise that is much bigger than bins, I think one should be
thinking in terms of dBm/Hz.  In other words, choosing a 5x narrower
span doesn't change the level of a carrier, but it lowers broadband
noise 5x.  So referring to "-100 dBm" seems to require giving the span
(or really the bin size, if one is comparing to non-Elecraft
panadaptors).

Continuous ?trickle charging? is neither necessary nor desired if you use low self-discharge NiMH cells.  The preferred ones around here are Envelop Pros ? 2550 mah, and they will retain 75-85% of their charge for a year or more in storage.  They cost a bit more than the cheap stuff, but you don?t want to use high self-discharge cells anyway.

Typically, I let my internal pack deplete to around 9v or a bit less, and then set an overnight charge for 12 hours.  The KX3 has a smart charger, so it won?t cook your cells.

Even if you normally use an external battery pack or power supply, it?s a good thing to have the internal batteries for a ?light? portable operation or if the DX is so good you drain your external battery pack :-)  Makes life a lot easier, and there?s less to haul around.

And yes, you DO make use of the 3 KHz roofing filter on SSB, and it is of value.

I had this problem in spades finding an antenna to use on my 
Miata with a Yeasu FTM-10R, which does 2M and 70Ccm along with 
AM and FM broadcast. The FTM-10R manual says, ?NOTE: An 
antenna designed with a matching device that forms a low DC 
resistance to ground may have poor recep on on the AM
Page 2
broadcast band.?

I finally parked the car outside our local Ham Radio Outlet and 
took antenna after antenna out to try them. I ended up with a 
Larson NMO-2/70 SH antenna which would receive AM and work on 
all the rest of the bands. In addition, it is quite small and 
doesn?t overwhelm the car.

My K3 hasn't traveled much, but if it did, I'd be very concerned about 
all the inductors supported only by their leads.  It seems certain that 
vibration would result in leads breaking.  However, there's a note in 
the KX-1 assembly manual specifically warning against fastening the 
inductors to the board with adhesive.  (That's exactly what I was 
planning to do.)  Why not?  I doubt the reason is electrical, unless 
it's stray capacitance.  The only other reason I can think of is that 
those handling power might get hot enough to melt an adhesive.  If 
that's the case, I'd really like to find another way to secure them.  
Any suggestions?

Or maybe someone can assure me that with all those K3 getting shipped 
all over the planet for DX-peditions, etc., none of those wires ever 
break.  Ever.  (I'd still take along some magnet wire.)

Most noise sources get weaker with increasing frequency, so there tends 
to be less noise on 10M and 6M because there's so there's much less to 
propagate.

Yes, and on 160M too.

Most spectrum analyzers are best used by setting  the threshold at the 
noise floor, and with averaging set to the maximum for the amplitude 
display. This will cause random noise to average out, making signals and 
correlated noise stand out.  Do NOT use waterfall averaging.  Also, use 
reasonable settings for SCALE -- I use 24 dB for general operating to 
find signals on a dead band, etc. and 42 dB for contests where many 
stations are running high power into big antennas. The only time I use a 
wider scale than that is when I want to look at sidebands of a 
transmitter working into a dummy load.

Don't view this as a "measurement," but rather as a graphic view of your 
RF environment.  Also, the settings noted above can help.

Yes, this is generally true, and the P3 can be set to automatically 
change the scale to compensate when changing the bin size (scan width). 
I don't remember if the PX3 firmware has that feature. But we don't care 
all that much about absolute levels unless we're measuring something, 
and when chasing noise, we're usually not measuring (except, of course, 
for seeing how much we've suppressed a noise source by applying a fix). 
But none of this logic applies -- we don't care about absolute levels, 
we only want to know if our fix helped and how much.

Thanks, all, for the information and opinions. Sometimes it's not what we
asked but what we /should/ have asked that's useful, either to the OP or
others. So I appreciate all the information and advice offered.

Some explanation: As it happens, I did read the installation sections of the
KX3 manual/manuals, which seemed well-written and clear. But, not having
seen a partially built KX3, it occurred to me that I might be missing
something. In the case of the K3, which I own but purchased used and
therefore did not have opportunity to build, there seem to be a few very
definite maxims for installing initially vs. installing later. I considered
that perhaps the same /might /be true of the KX3. I mean, the model
identifiers are quite nearly the same, aren't they? (Sometimes I think we
need and should have definite, reserved punctuation for sarcasm, humor.
etc.)

Living, as I do, in a recently constructed Southern California community, my
HOA has a rule that /absolutely/ prohibits visible and possibly invisible
transmitting and receiving antennas, except to the extent regulated by law.
So, at best, my HF antennas of record <cough> are severely compromised. When
one is driven to attempt using the rain gutter as an antenna, an antenna
tuner is more than a mere convenience. 

[Having used the H-- word, please let me offer a couple of precautionary
notes: Advice to move seems to me more than a little ignorant of the local
housing market--or perhaps just a great deal out of date. And unnecessary,
holier-than-thou statements such as, "I'd never live in an HOA community,"
are just that--unnecessary, most especially when the speaker/writer is
ignorant of the life-situation of the one whose choice as to only one
attribute of a multi-attribute preference is being publicly excoriated.
Being new to this board and having read only a few dozen or so replies to
postings, it is perhaps impolitic for me to say, but I think that in some
few cases, perhaps a somewhat better understanding of the context of an OP
and the OP's question might sometimes lead to very slightly more accurate
and practical advice.]

Thanks again!

Cheeeers,

Scott,

Read the warning on page 9 of the K3 assembly manual.
It specifically states:
"Also, do not attempt to fix the turns or coils in place with adhesives 
or other materials.
Those toroids needing support have been fixed at the factory. Adding 
material to the other
toroids will alter their inductance, again degrading circuit performance."

In other words, don't do that.  The K2 and K1 carry the same warning as 
the KX1.  I have encountered some of the Elecraft legacy gear in for 
repair that had the toroids fixed to the board with some kind of 
adhesive, it make them a mess to work with.
There have been several K2s that I know about which have been mounted in 
a high vibration environment such as the cab of an OTR truck, and the 
toroid leads have not failed.  The toroids were not fixed in place with 
any adhesive in at least one case - I know that because I built it for 
the customer.

If you do use a fixative, be aware that in the case of repair, toroids 
fastened like that are very difficult to remove and the board may be 
damaged in the process.  I have been there, done that.

Don W3FPR

Thanks, Tom

Hi,
The MIC SEL is front panel, Hi Bias.  I have tried all combinations too.

Tom,

Tap [1] to change the mic gain range to "L" and you should have more 
reasonable MIC GAIN settings.

Make sure you are FP.L Bias with an electret mic.  FP.H (or rP.H)
will make it nearly impossible to set mic gain levels as the
electret mic has approximately 20 dB more output than a dynamic
mic.

Subject: [Elecraft] Remote Antenna Switches and K2 Questions
Message-ID: <66DB8DA8-EB6F-4E26-AC29-23A139D5DA36@law.du.edu>

Two questions about the K2 and remote antenna switches ? particularly, the Ameritron RCS-4.

The K2 I finished building three months ago is finally on the air and, so far, working reliably, with great thanks to Don Wilhelm for his knowledge, skill, and patience.

It is now on its fourth set of PA transistors, plus a raft of other components in the PA circuits.  The story until now had been the same ? the rig works fine on Don?s bench; he returns it to me where it works fine with a dummy load on my bench at my city QTH where real antennas are forbidden.  I then take it to my operating QTH where my antennas are, hook it up, and within 20 minutes or less a loud pop and a puff of smoke precede the darkness.  PA transistors blown away again.  Three times, all the same.  Replaced power supplies twice, added cascades of surge suppression on the AC mains, no dice.  Sent the rig back to Don for another round of radiology and surgery.  Thrice.

This time, on a hunch, I removed one thing that differed between the operating QTH and the test bench in the city ? an Ameritron RCS-4 remote antenna switch.  With that out of the circuit, so far the rig seems happy.  No pop; no smoke; no darkness; no tears; no round trip back to North Carolina.

Don suspects the problem has been some mismarked component in the base K2 which, though it looked right, was of the wrong value and caused an imbalance between the two matched PA transistor circuits.  On the rig?s last trip to NC Don replaced virtually everything in those circuits.  And now it works OK, so far.

I wondered, though, if the RCS-4 could also be a culprit.  That switch inserts into the coax feed line the AC and DC voltages that energize its remote relays out where the antennas are.  According to the schematic there is no way DC voltage could appear at the input side of the switch console.  But with a DMM reading the Ameritron?s RF input side, I see some.  There are DC transients as high as 5 volts, negative and positive, occurring at odd times and of very short duration.  They have never seemed to affect the K3/KPA/KAT, nor the KX3/KXPA when these rigs are connected to the same RCS-4.

So, two questions:  First, is it possible that these weird transients from the control box could have been the cause of the PA failures?  Has anyone else ever experienced anything like this?  Second, rather than test that hypothesis by hooking the RCS-4 up to the K2 again, a test that could be expensive, I may just look for another remote switching system.  Any suggestions about a replacement?  If I need to use a separate DC voltage cable I?ll have to wait until the spring thaw in order to bury it ? but maybe the DC voltage insertion system just isn?t a good idea?

Tnx for any advice anyone can offer,

Ted, KN1CBR

For what it's worth, just my personal observations:

I drag my K2, K3 and just recently my K3S all over the place on my /p
outings all the time with no troubles. Now, one thing I did do was invest in
a good Pelican case for that purpose - yes, it was pricey at about $200 but
still a fraction of the investment in the rigs. So when bouncing around on
the floor of the pickup the rig is very well protected. I don't play soccer
with them for sure, but they do get bumps and thumps here and there.

But as for the inductors themselves, they look tiny and fragile, but they're
quite well supported by the leads and any vibration they may undergo looks
to me like it'd be well within the plasticity of the copper wire. On my K2,
I remember this when building my first one. I made sure to get the toroids
as well seated onto the board as possible and they're quite secure once
soldered in. 

On the K2 at least, the sensitive ones have precautions built-in, there's
one toroid (I think it's in the synthesizer) that's bolted down flat to the
board.  And the BFO toroid is secured by the resistor across its leads and
held firmly in place that way. The rest are in the low pass and bandpass
filters, so they're not as critical.

Don, please correct me if any of this is wrong (I'll get a review soon as
I'm now on the RF board build of K2 number 2 hi hi).

In other words, it's not a problem in my experience. Things like wiring
harnesses and big skeletal switch assemblies and so forth are what give
problems when schlepping a rig and none of the K's use those types of
construction. They're designed for portability in that way.

Just my .02,
LS

I have taken my K3 (S/N 6493), KPA500 and KAT500, in padded pelican cases,
over thousands of miles on the road with no apparent problems.  Of course,
this is anecdotal evidence, not before and after specification testing. But
my travel includes some of the worst Oklahoma county roads where there are
more potholes and patch bumps, than original road surface. Gravel washboard
would be smoother. If Elecraft didn't find a need for additional component
support after this many years, I trust their engineering. I worked in
mobile FM business and government radio manufacturing. Those radios
generally had no additional component support on PCBs. They were tested and
met some of the most severe vibration and temperature  specification
requirements.  Perhaps not a apples to apples comparison, but I don't
expect a problem with the K3 line.

Bummer!  That would certainly be a "missing dimension in feature space" 
given the increasing use of remote control.  I suppose it could be a 
result of the RemoteRig design, although at the remote K3, the audio 
from the RR codec goes into the mic connector.

Since 2008 k3 #679 has enjoyed life "on the road", constantly moving from one scenic location to the next.
Nothing seems to have been shaken loose over this time.
I would think by now that if anything was susceptible to working loose it should have had a Murphy incident by now?

Elecraft it appears knew about my requirement and developed the k3 just for this style of operating....grin

I have taken my K3 (S/N 6493), KPA500 and KAT500, in padded pelican cases,
over thousands of miles on the road with no apparent problems.  Of course,
this is anecdotal evidence, not before and after specification testing. But
my travel includes some of the worst Oklahoma county roads where there are
more potholes and patch bumps, than original road surface. Gravel washboard
would be smoother. If Elecraft didn't find a need for additional component
support after this many years, I trust their engineering. I worked in
mobile FM business and government radio manufacturing. Those radios
generally had no additional component support on PCBs. They were tested and
met some of the most severe vibration and temperature  specification
requirements.  Perhaps not a apples to apples comparison, but I don't
expect a problem with the K3 line.

A couple of stories regarding the travels of my K3.  Earlier this month
I was on Montserrat doing the ARRL SSB contest.  The day we left for
home, I had to stop at the local market on the way to the airport.  As
with many things on Montserrat, the market is on a hill with a driveway
that inclines upwards in the 30 degree'ish area.  When I stopped at the
market, the back gate of the car popped open and out came the pelican
case holding my K3.  Three bounces later, the case came to rest. So much
for the shock test.

The same K3 has traveled around Florida numerous times in my car doing
the Florida QSO Party.  That's the vibration test.

Frankly, I'm not losing any sleep over inductor failures.  I'm more
inclined to fail rather than the radio.  Numerous pelican-case
tripsaround the Caribbean for the K3 and even a trip to St. Croix in my
back pack. Will it ever break?  Maybe, but not going to look for a
problem when one doesn't exist.

 whips for KX3, etc
Message-ID: <201603262035.u2QKZrv1025769@mail40c28.carrierzone.com>

I might argue semantics with you, Charlie but get that most folks 
think a "base loading coil" is for use with shortened antennas 
(showing capacitive reactance).

The 5/8 WL Larson VHF whip (cut for 2m) does load nice on low end of 
6m.  In fact my antenna is a Larson  with NMO base mounting coil to 
NMO magnet.  Its on my truck so not accessible to check actual model 
but LM sound's correct.  I bought several at work for high-band VHF 
mobiles and recall some had HW or HD marking.

I can't recall if I every tried 6m using the Maxrad version which we 
bought later in the 15 years on my last job.  So maybe only the 
Larson brand will work this way.  We only had a few MOT antennas as 
they were cheaper without MOT brand on them.  We also installed DB 
Products antennas (not NMO base).

You can also buy the Larson NMOQ which is a 1/4 WL whip with NMO base 
but no coil.  I don't recall what whip length is supplied but I 
recall buying some mobile whips that had 96 inch whips which you 
trimmed with bolt cutters to resonant length (cutting charts were 
pretty good for obtaining good SWR on a mobile).

73, Ed

---------
This only works for a 5/8  wave 2 M antenna where
the base inductor (It's NOT a * loading coil)
isn't tapped and grounded at one end.
In other words, if there is a single connection to
the antenna, this will work.
If there's a ground connection such that the
inductor is tapped up the coil it will not
function on 50 MHz.
The Larson LM series will work, but ones designed
for the Motorola (NMO) base will not.

73, Charlie k3ICH

* A 5/8 wave antenna presents roughly 50 Ohms
resistive and some level of capacitive (-J)
reactance.
In order to match this impedance, a series
inductor is required to cancel the capacitive
reactance,
So technically, it is not a "loading" which would
be designed to make up for the fact that an
antenna is too short for a ? wave resonance.
-------
OR buy a 5/8 wave base-loaded 2m mobile whip -
loads on 50-MHz very nicely.  That's an old trick
for dual-band 6m/2m use.  Try brands like Larsen
or Maxrad.

Hi Ted,

I just looked at the schematic, downloaded from the Ameritron site, and 
wondered whether or not there are any protection diodes across the 3 
relay coils in the remote box. They do not show on the drawing.

I can imagine these spikes could be much bigger than the +5 and -5 volts 
you quote.

Subject: [Elecraft] K-3 Transmit Problem: no RF Output
Message-ID: <B9F2C010CE2D47A0B3CEDCC5A46CC331@X230>

Greetings -

My K3 has had low output for quite some time, maybe 60-90w depending on the
band.  I always meant to look into it and fix it someday.  Now it has no RF
output at all. (Just in time for VK0 and FT/J!)  I believe I have traced the
problem to two transistors on the LPA board (driver stages), Q4 and Q5, but
am not confident they are the only parts at fault.  I'm hoping someone else
has had the same problem and found the solution.

I tried re-seating all the connectors, with a drop of DeoxIt on the pins,
and running TX gain cal.  5w and 50w failed immediately, but 100 mW is OK on
all bands.

KPA-100 was removed, the PA jumper installed between P67A & P67B, and the
config menu was set to KPA not installed.  Measurements were taken with an
old Tek 2465.  DC voltages are all correct.

Measuring with a scope - I get a nice clean sine wave going in to the LPA
board at P71A pin 3.  Most bands are 1.2 to 2.2v P-P, but 6m is only 0.6v.
The output of Q1 is a little distorted.  The output of Q2 varies from
10-25v, depending on the band, and is also a little distorted.  Signals at
the base of Q4 and Q5 are back down to 3v.  Output of Q4 and Q5 is a few mV.
Changing the drive control has no affect on signal levels.

Is 1 to 2 v P-P the correct drive level at P71A?  What is an acceptable
variation in power level between different bands?  Should the drive control
change signal levels here, or does that happen later in the circuit?  I am
also concerned about the distortion on the wave forms.  Q4 and Q5 are
available from RF Parts for $5 apiece, so replacing them will likely be my
next stap.

Thank you.

K3support can give you a couple places to make measurements to determine 
whether the LPA transistors are good or bad.
I forget what those measurements are, but I suggest you contact them.

Thanks for the note, Peter.  I haven?t opened the relay box, not wanting 
to break whatever weather seal it still has (besides,  it?s snowing and 
blowing out there); but I don?t know why a schematic would leave out 
anything that?s actually in the equipment.

I?ve had a half-dozen off-list replies to my original post, almost all of 
them noting the three parallel caps that pass the RF input and 
theoretically isolate it from the relay voltages.  If any of them failed, 
there could be DC showing up at the RF input.  Don Wilhelm pointed out 
that because the LPF in the K2 is grounded on one side the presence of DC 
itself wouldn?t be a problem, but that rapid changes in any voltage 
getting into the RF input side could be. (Do I have that right, Don?)  The 
curious thing, though, is that I have two Ameritron RCS-4s, and these 
voltage anomalies appear in both of them in almost identical ways.  Maybe 
a design flaw rather than a component failure?  In any case, something 
caused multiple failures when the K2 was here, but not when the K2 was 
anywhere else; and having the RCS-4 in the line here is the last such 
difference I could think of that hasn?t already been ruled out.  So maybe 
it has been a K2 component problem, but maybe not - three nearly identical 
failures make that seem less probable than only one would, but snot 
unlikely.

What I?ve measured with the DMM are short bursts - and, in fact, at one 
point I saw a reading of over 18 volts as your note suggests might be 
possible.  I am bringing one of the units back to the city with me Monday, 
where my oscilloscope is, so that I can get a better picture of what these 
transients look like.

For now I am just being wary of a system that inserts the relay energizing 
voltages into the coax.  The disadvantage of the alternative, meaning a 
separate low-voltage cable from the control box to the relays, is that 
it?s another cable.  For reasons of good domestic relations the coax from 
the house to the common antenna feed line site is buried.  Any other 
cables running that way would have to be as well.  From the looks of 
things today it may be June before the ground at this altitude (8,600 
feet) thaws enough to allow for even shallow trenching.

My thanks to everyone who replied with observations and suggestions.  This 
list is a never-fails resource . . .

Ted,

Yes, you have that right.
Capacitors or diodes across the relays would be a good thing to swallow 
the voltage kick when the relay is de-energized.

If your DMM is showing voltages in excess of 13 volts, then the peak 
voltages will be much higher.
The diodes or capacitors would have to go into the remote box across the 
relay coils.  If diodes are used, observe the polarity carefully - the 
cathode must go the the side of the relay with the more positive voltage 
- in other words for those relays driven by negative voltages, the 
cathode goes to the side with the negative voltage closer to zero volts.
Diodes will do a better job than capacitors.  If you use capacitors, I 
would suggest 0.1uF although 0.01uF may be sufficient - it all depends 
on the inductance and resistance of the relay coil.

Don W3FPR

Hello,

I have removed the "Split +1" macro, and replaced it with a Split-5
macro. ?This now gives both Split +, and Split - macros...

the new Macro is as follows:

BW0001;SWT13;SWT13;FT1;DNB7;RT0;XT0;#SPN000060;#RCF-002500;BW0280;

BW sets bandwidth to as narrow as possible...
SWT is the same a pressing A->B twice
FT1 puts things in split mode
DNB7 is down 5, (really it is)
RT/XT clear XIT, and RIT
SPN sets span to 6 KHz.
RCF- moves the DX frequency to the right side of the P3 display
BW sets the RX bandwidth back to 2.8 KHz.

This is also a slight change from the original macro... ?This version
gives a narrow transmit marker, as opposed to the wide one of the early
days... ?Adding the BW commands at the start and finish perform this
function.

The change occurred to macro 38 in the spread sheet...

The spread sheet can be downloaded at:

Looking a the schematic it appears they use 0V, +V, -V and ACV for the 4 switching states but only + or - voltage is applied to the relays. The big cap is used to smooth out the AC ripple.  I would put a back diode across each relay coil and add a MOV of appropriate voltage across C203 (V to ground).  Reference the QST article in January 2013 issue. I built one with those guidelines and it's been fine for a couple of years.

Good Day,
     After a month filled with antenna part delays and bad weather I 
finally have replaced my antenna.  I hope to put up a few more soon.  
Luckily it started to hail as I was hoisting the center line.  For the 
next twenty minutes the ice kept falling as I wove the legs of the 
doublet through the limbs toward their guy points. I still need to thin 
the brush but the antenna is working fine (without the aid of 
propagation).  The 14 gauge THHN wire I chose was easy to pull through 
the brush.

I have a related question: I purchased my K2/100 only a month ago, second
hand, SN 5818.  I've experienced "PA HOT" shut down on several occasions
when running 100Watts out, and less frequently but it has happened when at
50Watts.  I've witnessed the discussion of setting Cal tPa to ambient temp.
C, and with my indoor/outdoor digital weather monitor on my operating desk,
I see 81 F as a normal workstation temp, which converts to 26.95 C......
that is the figure I enter into the Cal tPa setting.  I can then operate CW
for a few minutes, noticing that the fan does turn on.  Unfortunately, since
I do not continually keep my eyes on the digital display as I continue my CW
qso, I have been frequently surprised to note that I have experienced a Pa
Hot failure and my output has shut down (although the side tone monitor
continues to yield my keyed side tone).  

I have now noticed that when that failure occurs, I can power down the K2
and immediately power it pack on, and I then can continue operating with
full output power.  This almost appears as if the Pa Hot error is a false
indication, and even though it initially shuts down my output power, it
seems strange that it resets to normal ops when power is cycled off and on
again.  I have failed to notice if the fan comes on upon the power off/on
recycle..... I'm thinking it is not on at that time.  I'll try to be more
observant on future failures but in the meantime I wanted to mention this
failure in case I am overlooking something or maybe doing something to
create harm by powering off and on the K2.

PS.  While attempting to change the failing conditions, I have increased the
Cal tPa temp up to as high as 33C, and I believe that is where it was set
with my most recent failure.

Any ideas out there?  Thanks.
Mike, K5MP

Mike,

First, the menu CAL TPA parameter will indicate the temperature of the 
heatsink if all is working normally.  That is why you let the heatsink 
cool to ambient temperature before setting CAL TPA.  If you have a 
temperature probe that can measure the heatsink temperature at the PA 
transistor mounting point, you don't have to let it cool to ambient, 
just set it to the actual heatsink temperature - but most hams do not 
have accurate temperature measurement equipment, so cooling to ambient 
is the normal procedure.
Set CAL TPA first before proceeding with anything else.

Did you purchase this KPA100 as a new kit or did you purchase it used?
It may have a fault or a badly soldered connection that changes when the 
temperature rises - but I suspect you may have a power control problem.

Make a check on the power output - connect it to an external wattmeter 
and a dummy load.
Set the power level for 50 watts and do a TUNE - the power on your 
wattmeter and the K2 display should indicate about 20 watts.
If you see 20 watts on both the K2 display and the external wattmeter, 
then proceed and do a TUNE/DISPLAY - in other words, depress both the 
TUNE and DISPLAY buttons together.  You should see about 50 watts 
indicated on both the external wattmeter and the K2 display.

If either or both those tests fail, I suspect you will see a low power 
indicated on the K2 display while seeing a high power (120 watts or 
greater) on the external wattmeter.
What that means is you have no power control and the KPA100 is going to 
its fully capable output at all times.
The cause of that behavior is damaged diodes in the KPA100 wattmeter - 
diodes D16 and D17 located on the board close to the SO-239 jack.

In other words, if your KPA100 is going to full power output all the 
time, it will heat rapidly and give you a PA HOT message.  More common 
is a HiCURR message, but if you have the CAL CUR set above 3.50 amps, 
you may not get that warning.

If the power control is working normally, then you should look into the 
PA Bias and the temperature sensing transistor Q3 or its input to the 
Firmware IC U1.

Yes, it is OK to turn power off or even to pull the power plug, that in 
itself will not cause a problem with the K2 - the K3 and KX3 are 
different in that respect, and they should be powered off normally.

73,
Don W3FPR

Subject: [Elecraft] Feature request: Command line firmware updater
Message-ID: <CALQT3yzBY=nt4KhY4umiuASOCasnhePaGjRGD69HbcjUGKdA-g@mail.gmail.com>

Hi folks,

As the subject suggests, I'd like to put in a feature request, for a
simple, command line firmware updater tool, for all applicable Elecraft
rigs. To update the firmware on my KX3 and PX3, I need to download and set
up two separate programs, most of whose functionality I won't ever need.

Such a tool would be easy for Elecraft to write and maintain, and would be
easy to make work on different platforms, which brings me to the next part
of this feature request. I'd like to be able to run this tool both on my
Intel Linux machines, and my Raspberry Pi, which is hooked up to my KX3 and
PX3 whenever my KX3 is home. Cross-compiling such a simple tool should also
be pretty easy.

I'm sure there are other people who're in similar situations, and would
appreciate something to address these use cases. Firmware updates are one
of the few things where you can't roll-your-own.

Thanks.

Bruce

Good Evening,
     I was able to raise a decent antenna this week and ran both Sunday 
nets.

I worked:

W0CZ - Ken - ND
K4JPN - Steve - GA

On the twenty meter net at 14049.5 kHz.

And:

NO8V - John - MI
K0DTJ - Brian - CA
K6PJV - Dale - CA
W0CZ - Ken - ND
W6JHB - Jim - CA

I checked the Reverse Beacon Network after each net to see how my signal

If you live in or around any of these "preferred" landing areas for my 
signal you could try next week's ECN sessions.

But perhaps you could write your own updating 
utility, Bruce. While I have an RPi2 running 
Linux, etc. I'm very happy with the OS-dependent 
utilities we have now. Likely a command line 
utility would not be as capable and could cause 
problems if the command line was not just so.

so, but they don't appear to be. I assume they are the "reserved" commands
listed in the programmers references.

Richard,

Those are two totally different things.
The P3 display will show you the PSK or RTTY internal decode on the P3 
display, and you can send RTTY or PSK from the K3 paddles by keying CW 
characters.  With the SVGA option for the P3, you can use a keyboard to 
send those characters.  Using the K3/P3 decode, you would tune to the 
signal of interest with the VFO knob, and the bandwidth should be narrow 
to home in on one signal.  The P3 shows the signals prior to the 
filtering in the K3S, and you can click on the signal of interest.

FlDigi will give you a similar waterfall display (but it is after the 
filtering in the K3) - the K3 would be operated in a wide bandwidth, and 
you would use the FlDigi software to click on the signal of interest and 
it would be decoded for you - the software does the decoding, not the K3.

So the answer is that the difference between the P3 display and the 
FlDigi waterfall display is two different questions.
The K3S will decode PSK and RTTY signals without the P3, so try it that 
way and see if it does the decoding job for you in VFO B display area.  
If you have positive results, then the P3 may be an answer for you.

I have used both, and my preference for general operating is to continue 
with FlDigi, but the K3 decode as displayed on the P3 is good as well.
If the band is crowded, you may find the K3/P3 operated with a narrow K3 
bandwidth is better, but for general operating, FlDigi will be the 
better choice fir normal conditions.

Don W3FPR

Hi Paul / N6HZ

I?ve downloaded the beta version 1.42.

And I tried to install the beta version, but the PX3 will become off.

I tried to install the current version, the PX3 does not turn off.

Best regard,

Nakamura / JE0LFI

Subject: [Elecraft] ERR KEY
Message-ID: <56F91B85.6000008@gmail.com>

This past weekend I experienced numerous ERR KEY messages. According to 
the manual, this ERR code is returned when one "attempts to key the 
transmitter or activate PTT during power on". When this would happen, 
there was no power turn on, nor shorted keying lines- it was in 
operation with N1MM+ in an SO2R mode.

What else would cause that error message?  If I tried to key the radio 
before the PTT had been fully asserted, would I get that error?  I am 
thinking that there is some connection between that error message and 
some timing elements of the PTT/Keying process that I could correct.

I have another op that is getting this error in an unrelated setup. We 
are both using the latest K3 firmware, 5.38.

I have both K3 and KX3 and I sometimes use them outside in a field 
operation. Here in Russia we have one funny QRP contest called  "Frost-red 
nose" where extra points are given for low temperature environment during 
field operation. The contest happens in January when in some places 
temperatures can be down to minus 30 C. I did not find temperature 
requirements for K3/KX3 in the specs. Can somebody give me a hint or may be 
share own experience. What would be the lowest temperature where the rig 
will still perform adequately?

Message-ID: <CAKXfWbSr6vO79HObDxeNb8fXeuAt_JF12v4M8L0g9nQGFAEcvA@mail.gmail.com>

I became enamoured with N1MM+ after this weekend's contest and wanted to
see if I can use it for other stuff like CW. I got the keying working with
my K3S so that's no problem. The issue is I can't decode 30 WPM CW in my
head. I need help.

I've been using the K3 Util terminal for CW contests and that's worked out
well. I wanted to see if I can use both N1MM+ and K3 Util and share the COM
port with LP-Bridge, but apparently K3 Util doesn't work with LP-Bridge. I
also tried using FLDigi but the results weren't too great. It doesn't
decode most of the time.

Any suggestions (besides suck it up and learn to decode high speed in my
head)?

Were you remote, Dennis?

I notice on the VY1AAA remote, if the sequencing is not right, I would get
ERR_KEY on the rig as well.
It seemed to happen just as I was logging a QSO (no ESM, just VOX).

This was Windows 10 locally, with the RRC.  I wonder if this is the dreaded
serial overlap issues that the N1MM and Microbit team has discovered
(manifests itself by causing WinKey to stop sending after a few characters
on CW.)   May be a completely different issue.

I do have an op that is having problems with this in conjunction with 
his Remote Rig setup, but that wasn't the case for me this past

Message-ID: <em2500026a-2c51-45b2-8711-76493a4714f8@jimsdesktop-pc>

Peter,
None of the decoders out there, including the better ones (internal to 
the K3/K3S and the KX3) decode CW even close to accurately unless the 
conditions are ideal and the sending operator is close to perfect in 
his/her sending so the ultimate answer is "suck it up" and learn to 
decode it in your head.

If you rely on the decoders, you will have difficulty in actually 
learning to copy in your head and you will get enough call signs wrong 
in your contest logs that they could even be rejected due to too many 
"busted" calls.

That being said, as for the decoders, I was a Morse Intercept Operator 
during the first 6 years of my 20 year Army Security Agency career.  I 
had the copying of Morse code drummed into my head 8 hours a day, but 
that was copying mostly 5 letter or number coded groups on a typewriter. 
  It took a large amount of money to train us electronic spies, and the 
NSA decided to design a decoder to replace us, figuring that a computer 
could do a better job.  They spent several millions of dollars on this 
electronic black box (back in the 60's) and discovered that the human 
brain was a much better decoder than a machine could ever be.  Every 
little static burst would disrupt the decoding and it would take a few 
characters to catch back up.  Also, if the code wasn't being sent by 
automatic means (in those days that was a punched paper tape) and the 
receiving conditions weren't very close to perfect (almost never happens 
these days and even worse back then) the decoder output gibberish.  
After a couple years of mostly abject failures and after spending 
millions of dollars, they abandoned the project.

Wayne and others have done a marvelous job of computer coding, allowing 
the firmware in Elecraft's radios (and other stand-alone devices) to 
decode CW, but the above conditions apply to them as well as to NSA and 
NSA spent a heck of a lot more money trying to achieve perfect copy than 
Elecraft had in their coffers.  Bottom line, use it for occasional help, 
but work at learning to read it in your head yourself.  It isn't as hard 
as most people make it out to be and all it takes is practice.  That's 
the absolute bottom line, it takes practice.  If you are willing to go 
the extra mile and put in that practice, the rewards will outweigh the 
initial frustrations.

73 and good luck,
Jim Sheldon - W0EB

Hi Dennis,
Good for you!  N1NN+ is great and CW contesting is even better.
There are a couple of programs that will help you improve your copy for call signs and numbers.  These are Morse Runner and Rufz.
http://www.dxatlas.com/morserunner/
http://www.rufzxp.net/

Morse runner even simulates N1MM in a pileup and you can adjust the speed, pileup conditions etc.
Rufz sends one call at a time and if you get it right, ups the speed for the next one, wrong, slows down a notch.

Try to develop the following habits:
In Morse Runner Hit enter to start sending the call before you type the last letter of the call.
In Rufz when speeds get high, let the whole call go by before you type it it.

Use these a few minutes each day and you will be amazed how much better you will be.

I think W1UE is already a very proficient CW operator! I had the ERR Key
message while operating as WP2AA this month. If I recall it was from
accidentally plugging the headphones into the PTT connection of the Heil
mic adapter. It was a little bit of a scare just minutes before the ARRL
DX Phone contest started! Assuming that everything is wired correctly,
could there be a timing issue with your N1MM PTT?

Rufz sends one call at a time and if you get it right, ups the speed for the next one, wrong, slows down a notch.

Try to develop the following habits:
In Morse Runner Hit enter to start sending the call before you type the last letter of the call.
In Rufz when speeds get high, let the whole call go by before you type it it.

Use these a few minutes each day and you will be amazed how much better you will be.

Subject: [Elecraft] OT: Decoding high speed CW

I became enamoured with N1MM+ after this weekend's contest and wanted to
see if I can use it for other stuff like CW. I got the keying working with
my K3S so that's no problem. The issue is I can't decode 30 WPM CW in my
head. I need help.

I've been using the K3 Util terminal for CW contests and that's worked out
well. I wanted to see if I can use both N1MM+ and K3 Util and share the COM
port with LP-Bridge, but apparently K3 Util doesn't work with LP-Bridge. I
also tried using FLDigi but the results weren't too great. It doesn't
decode most of the time.

Any suggestions (besides suck it up and learn to decode high speed in my
head)?

Message-ID: <CAJ-xeH=ZuDMd1fniYObDyRMp_abHpmZfFFLPYEOUwUTbYMqg0A@mail.gmail.com>

Dennis,

Some questions that might perhaps throw some light on what is happening:

What method are you using for CW keying? Are you using PTT control in CW?
How is N1MM+ configured to do CW and PTT keying?

One particular area to look at:

What is CONFIG:PTT-KEY set to on the K3? In the N1MM+ configuration is the
CW/Other check box checked for the radio control port, and what are DTR and
RTS set to for that port?

Rich VE3KI

Subject: [Elecraft] ERR KEY

This past weekend I experienced numerous ERR KEY messages. According to
the manual, this ERR code is returned when one "attempts to key the
transmitter or activate PTT during power on". When this would happen,
there was no power turn on, nor shorted keying lines- it was in
operation with N1MM+ in an SO2R mode.

What else would cause that error message?  If I tried to key the radio
before the PTT had been fully asserted, would I get that error?  I am
thinking that there is some connection between that error message and
some timing elements of the PTT/Keying process that I could correct.

I have another op that is getting this error in an unrelated setup. We
are both using the latest K3 firmware, 5.38.

+1 to what Fred Cady said. ?I'm a fairly new CW op and just graduated from CW Academy level 3. ?In that class, they teach you how to head copy high speed contest CW, primarily using Morse Runner and RufzXP, but also by live practice in the weekly CWT tests. ?If you want some free, structured, hands on training, I can't recommend CW Academy highly enough. ?http://www.cwops.org/cwacademy.html

Don't feel too bad, I kind of have the inverse problem: I can copy at a much
greater rate than I can send lol. Also, I never learned to translate CW into
keyboard keystrokes, mainly because I just refuse to get a computer anywhere
near my rigs lol.  I prefer to just pound brass, so I think I'm doomed to
S&P in contests, even tho I've learned to copy calls and contest exchanges
at reasonably high speeds.

As for copying in one's head, I know I'm drifting slightly off topic, but
just a couple tips for free that helped me:
- the key to getting above about 25 wpm on plain language is to start
learning the CW for entire words or parts of words: "the", "and", and
segments like "tion", "ing", etc. Instead of discrete letters, learn what
entire words or frequent endings sound like. Then in a pinch you can decode
individual letters that you may have missed by not having to decode the
familiar-sounding ending or even guess from context what the entire word is.
- for call signs, which are basically just code groups, be familiar with the
patterns - 1-2 letter/number/2 or 3 letters, etc. That will help you store
those and limit the amount of brain power you have to devote to decoding a
call at high speed. Not infallible but it helps.

For learning words, W1AW code practice .mp3's on arrl.org are really good
for practicing this. For call signs, well, just listening during a hefty
contest is what I do.

Anyway, back to the regularly scheduled program,

73,
LS

+1 from me. ?I recently finished CWA Level 3 and with the 8 week class and lots and lots of practice moved from a comfort level of 20 wpm to comfortable head copy at 30 wpm. ?Just be aware that because of demand for the classes and a shortage of instructors you may have to wait six months or more from signup until your classes begin. ?It is well worth the wait if you want to improve your CW chops. ?Highly recommended. ?The instructors and classes are phenomenal!

I agree. To paraphase the musician's gag -- "How do you get to Carnegie 
Hall? Practice, practice, practice."

The good news is that turning off your decoder and working a CW contest 
with your ears and brain can boost your copy speed by 5 WPM (or more). 
And I agree with recommendations that you spend some time with 
MorseRunner http://www.dxatlas.com/MorseRunner/ MorseRunner was written 
by VE3NEA, author of CW Skimmer and more than a dozen other very useful 
ham programs. MorseRunner and PileupRunner are free; some of the others 
are paid shareware.

And if your schedule and the availability of CW Academy classes permits 
(they tend to fill up in advance), by all means sign up.

Same here, LS. As I've gotten older my muscle 
coordination has deteriorated a tad, so ...; most 
seemed to result from an open heart surgery I had 
three years ago which also killed my kidneys 
(which came back after five weeks of dialysis -- 
whew!), making poor CW sending seem a minor price 
to pay).

Or maybe that's just a good excuse :-)

Well, to take the other side for a moment, I promise I'm not a curmudgeon hi
hi. I'm a software engineer in my day job and am accustomed to embracing new
technologies when required; I have a lot of admiration for things like
MorseRunner and CW Skimmer & reversebeacon.net and so forth.

All that said, I did get my novice at age 10 when you only had 2 years and
that was it unless you upgraded, and CW and 75W input was all you were
allowed to use. So I started off pounding brass and somehow never went away
from it since. 

So all that's just a qualification to take my comments with a grain of salt
- it's my fault that I never learnt to use a paddle very well or how to
shield my rigs from computer RFI, etc. not the technology.

But once I get setup at home with either a Windows box or a suitable VM on
my mac, I definitely _will_ start using MorseRunner. I definitely need some
sustained practice at 30wpm + that I don't get to have as much as I'd like
just S&P during contests....

Morserunner works under Wine on my Mac, or at least it used to. I quit
using it because it would suck me completely in and then several hours
would disappear. And none of those computer QSOs would QSL! :)

Jim, Paul
Paul, Jim is correct. Practice, practice, practice, then sooner than not you
will be copying in your head.
Jim's ASA training and experience works for him. For me it was USAF CW
Intercept and over 7 years experience. I don't use skimmers or cw decoders.
My K3 has one, and to be honest, I use it very infrequently, mostly to check
on the other guys/gals speed when it gets up there. I may have to hear a
call more than once, at 35 or higher, but not often. It's usually the
QRM/QRN that gets you. Then there's the QSB. Ever copy "weak" sigs Jim? 
Do your practicing "On the Air", not by machine, if you can. W1AW code
practice is good, and there are others out there I believe as well. Start at
a speed you can copy fairly well, then work up from there. I wish you well,
and welcome to the world of CW.
Jim and I might even have to chat off list. Have to figure he was in Germany
also.
Take care and have fun.

Rick, W7LKG

Peter,
None of the decoders out there, including the better ones (internal to the
K3/K3S and the KX3) decode CW even close to accurately unless the conditions
are ideal and the sending operator is close to perfect in his/her sending so
the ultimate answer is "suck it up" and learn to decode it in your head.

If you rely on the decoders, you will have difficulty in actually learning
to copy in your head and you will get enough call signs wrong in your
contest logs that they could even be rejected due to too many "busted"
calls.

That being said, as for the decoders, I was a Morse Intercept Operator
during the first 6 years of my 20 year Army Security Agency career.  I had
the copying of Morse code drummed into my head 8 hours a day, but that was
copying mostly 5 letter or number coded groups on a typewriter. 
  It took a large amount of money to train us electronic spies, and the NSA
decided to design a decoder to replace us, figuring that a computer could do
a better job.  They spent several millions of dollars on this electronic
black box (back in the 60's) and discovered that the human brain was a much
better decoder than a machine could ever be.  Every little static burst
would disrupt the decoding and it would take a few characters to catch back
up.  Also, if the code wasn't being sent by automatic means (in those days
that was a punched paper tape) and the receiving conditions weren't very
close to perfect (almost never happens these days and even worse back then)
the decoder output gibberish.  
After a couple years of mostly abject failures and after spending millions
of dollars, they abandoned the project.

Wayne and others have done a marvelous job of computer coding, allowing the
firmware in Elecraft's radios (and other stand-alone devices) to decode CW,
but the above conditions apply to them as well as to NSA and NSA spent a
heck of a lot more money trying to achieve perfect copy than Elecraft had in
their coffers.  Bottom line, use it for occasional help, but work at
learning to read it in your head yourself.  It isn't as hard as most people
make it out to be and all it takes is practice.  That's the absolute bottom
line, it takes practice.  If you are willing to go the extra mile and put in
that practice, the rewards will outweigh the initial frustrations.

73 and good luck,
Jim Sheldon - W0EB

Yeah, but it is a real kick when the program sends your call to you which can happen if you are practicing with a dx call!

Seeing Rick? post has me thinking? I rarely use my KX3 for decode CW but? maybe a future feature is to have a one button ?speed is? on the KX3?
I know it is ?there? but one key touch would be a nice feature to see how fast the other guy is moving at.

I'm considering adding a THP HL-1.2KFX solid state amp to the K3S station I
have, and was wondering how others have done this. There seems to be
conflicting info on the "right way" to do things.

1. The THP manual states that ALC should be used to control the amp, but
2. Elecraft support (and documents) suggest that ALC should not be used for
any amps.

Of course, that begs the question "Why is ALC included at all on the
K3/K3S?", but...anyway.

Elecraft support suggested I ask the reflector what other folks do, so I
am. Looking forward to your replies.

Thanks!

Most of my CW work is for eme where the signal is marginal "at 
best".  Without having a large SNR on the signal I have not found any 
CW decoder to work well (skimmer seems to be best).  On CW-eme the 
output is gibberish.

Inventing a digital code designed for weak-signal is way better 
solution (eg JT65) and it decodes down 10-dB weaker than most folks 
can hear CW (I need another +6 dB for human CW copy).  Good CW ops 
prefer CW as it is "more fun" than digital - no argument.

So, CW was designed for human decoding and that still remains the 
best solution.

John,

I don't know what other folks do, and I don't have an amplifier, BUT ---

Using amplifier ALC is a good way to create splatter on the bands, so it 
should not be used if you are to present a clean signal.  ALC can be 
used as a crude means of power control - the amplifier is overdriven, so 
ALC activates and the drive power is reduced at the driving 
transceiver.  That is the "bad" use of ALC.  I know of at least one 
amplifier manufacturer which instructs the user to run the driving 
transceiver at full power and let the amplifier ALC control its power 
output - don't do that, it causes splatter on the bands because that 
control mechanism is not instantaneous - you go into an overdrive 
condition before the power can be reduced.

However, some solid state amplifiers also use it as a means to shut down 
the driving transceiver if it detects a fault condition.  The use of ALC 
for that purpose is justified IMHO.

Most amplifiers have a control which can set the ALC level.  So if you 
choose to use the ALC line for amplifier fault protection, then set that 
level well above the point where ALC will be activated by the amplifier 
for power control purposes - otherwise just adjust the drive power of 
the K3 to drive the amplifier to the desired power output and do not 
connect the ALC.

Just a point of opinion, I think the amplifier designers who like to 
depend on ALC for amplifier fault protection should find a different 
way.  If the amplifier is in a condition where it needs to reduce the 
power, that should be done in the amplifier itself without reliance on 
any external device, and that includes sending ALC to the driving 
transceiver.

Don W3FPR

Subject: [Elecraft] ERR KEY
Message-ID: <56F9ABAB.6070101@gmail.com>

I wrote earlier today about what triggers the ERR KEY error on the 
screen of the K3.  I have had several suggestions about what it is, so 
I'll reply to them generically.

The contest this past weekend was an SSB contest.  The ERR KEY message 
(and not ERR PTT) appeared 40 or 50 times.  Yes, there was a cw keying 
line attached to the radio, but it was never used.

The CONFIG:PTT-KEY in the K3 menu is OFF-OFF.  The radio control part of 
the N1MM+ software had DTR and RTS both off.  None of the PTT via 
hardware options was checked.

I happen to be using an SO2R Box, but others that have told me they are 
having the same higher incidence of ERR KEY messages

The ERR KEY message seemed to be associated with use and stopping of the 
Dueling CQ function of the N1MM+ software.  The Dueling CQ function 
would be stopped by entering something in an EW.

Both radios were connected to the computer via real Com ports.  No USB 
to Serial converters were involved.

I have been told by at least 6 other ops that they have seen an 
increased incidence of ERR KEY messages.  I don't know what firmware 
they are using, but I know I am using 5.38.

The ERR KEY seems to be related to PTT timing, but I'm not totally sure.

If I could find other reasons why the K3 was producing that error, I may 
be able to come up with a fix, either in software,  in someone's 
firmware, or in some setting within the K3 Config menu or N1MM+. Right 
now, the only definition I have of the ERR KEY concerns shorting the 
keying line when the rig is turned on, which definitely is not the case 
here.

Haven't tried it yet on the P3 but for the same feature on the PX3 if you make the RCF value a bit less than the span you can use Half span or Full span.  
So a macro
#SPN000100;#RCF+004500; will set the span to 10 kHz and position VFO A just above the left side of the display.

Cheers,

All - I'm about to write a president's letter for our local club 
publication on learning CW, and this entire thread is a good 
source of ideas. Thank you.

Peter -

I learned 5 WPM in 1960 for my novice license, but never used 
it. I learned 5 WPM again in 2001 for my extra, but didn't start 
using it until 2013. TX5K is the first CW QSO in my log and 
W6SQQ is the 2nd QSO and first rag chew. My learning CW at age 
70+ is definitely an example of old dogs and new tricks.

Now I am mostly operating in contests and chasing DX with about 
the same abilities as you have. I can use a straight key up to 
about 18-20 WPM, but I haven't gotten the timing right for a 
paddle. Most of my sending is from K3 memories or my contest logger.

My survival strategies are:

   In contests I only search and pounce. I can hear the other 
op's call many times and get it right. I'm working on getting 
good enough to run.

   With my 100W and wire antennas, I get a lot of chances to 
listen to DX stations handle other callers. It is good practice 
to try to decode the call signs they're working. (It also helps 
locate the caller in the pileup.)

   I use the K3's decoder and display in the P3's SVGA. That 
keeps the decoded data from disappearing off the screen before I 
read it. (Note that the SVGA display can't be used if the 
computer is also reading the decoded data via the K3 utility or 
some other program.) The K3's decoding acts as a check on my 
head decoding.

   If the DX is only rarely identifying, I see if I can find him 
on the QRZ.COM DX spotting network. It is a lot easier to verify 
a call sent faster than you can read than it is to copy it.

LS is absolutely correct (below). When you get to 20+ WPM, CW is 
no longer an encoding system. It is a language of its own and 
should be approached like any foreign language. The big win for 
contesting and DX is that the vocabulary is so small. For things 
like 5NN, TU, CQ, DE, TEST, UP etc., I don't even think of the 
letters. The CW sequence is a spoken word and understandable as such.

I'll keep hanging in there and hope you do too.

Yes, that message should only occur if the key line or PTT is shorted

Just a quick point of clarification (since I did my graduate work in a
similar field). I would say it's more like a "pidgin" language in contesting
exchanges, yes, but in a regular QSO, CW is still basically just an encoding
system for the underlying language the QSO is in. 

The only difference is in the representation of the "items" of that
language: they are now represented by CW rather than the sounds made by the
human voice. Putting it another way, you're not having to relearn English
when you take up CW, but only a new representation for the "pieces" of it
(words and parts of words). 

That would explain why, for example, your copy speed will drop (sometimes
dramatically) when the content is blocks of random letter/number groups
instead of plain language, or if you're reading the mail on a QSO in another
language like Spanish or German (and you don't speak those languages). 

And (though by now you know where my comment is going hi hi) why your copy
speed can drop dramatically when it's 90% call signs like in a contest.
You're not totally at sea, since we have a definite and small set of
patterns to go by with calls and the format of contest exchanges (regarding
my 'pidgin' judgment above), but that's why contest QSO's kind of need their
own copy practice...

Subject: [Elecraft] fldigi KX3 question
Message-ID: <002d01d18946$6e575bf0$4b0613d0$@comcast.net>

I am new to fldigi.  I am using the SignaLink USB to interface between my
KX3 and computer.   I have my KX3 connected to fldigi using Hamlib rig
control.  That seems to work fine tracking the VFO and placing software into
the right mode when I change it on the KX3. First, could someone tell me
what power output I should be using for psk31, RTTY, and some of the other
digital modes supported by fldigi?  I do have the KXPA100 if I need more
than 10 watts power.

 

I can receive digital modes just fine.  I am still trying to identify the
various sounds other than PSK31 and RTTY which were the predominant ones I
used about 9 years ago before my hiatus from Ham Radio.  

 

I turned my power down to three watts just to make sure I was not
overdriving anything.  I tried PSK31 and RTTY on transmit.  The KX3 went
into transmit mode when pressing the TX button.  When I press the RX button,
the transmit of the baudot idle string for example in RTTY stops, but the
red transmit light stays lit.  I have to manually press the XMIT button to
turn off the transmit light.  Same thing happens in PSK31.  I must be
missing some setting in fldigi and I hope someone can tell me how to get the
KX3 to go back into receive mode.

 

Thanks,

Terry,

What data submodes are you using?

Fldigi is a soundcard oriented application and you should be using DATA 
A for PSK and AFSK for RTTY.  If you are trying to use data submodes of 
PSKD or FSKD, you will receive just fine, but transmit will not happen 
with Fldigi.

Typically, PSK will work fine at low power levels, but the RTTY folks 
tend to run at higher power levels.  You may manage on RTTY at 5 watts, 
but the full 100 watts from the KXPA100 will give you better success rates.

Note that the default bandwidth for DATA A and AFSK A data submodes is 
narrow on the KX3.  You will want to widen the bandwidth to give you a 
full waterfall display on Fldigi.  Click on the signal of interest to 
decode it and you should transmit on that frequency.

Fldigi does not have an idle timeout, and that is what is telling me you 
are trying to work with Fldigi in PSK D or FSK D data submodes. Those 
work from characters entered via the paddles keying CW or in ASCII 
characters from KX3 Utility terminal tab, but will not work with the 
audio tones provided by Fldigi.  Use DATA A mode for PSK and other 
digital modes, and AFSK A for RTTY work.

I'm considering adding a THP HL-1.2KFX solid state amp to the K3S station I
have, and was wondering how others have done this. There seems to be
conflicting info on the "right way" to do things.

1. The THP manual states that ALC should be used to control the amp, but
2. Elecraft support (and documents) suggest that ALC should not be used for
any amps.

Of course, that begs the question "Why is ALC included at all on the
K3/K3S?", but...anyway.

Elecraft support suggested I ask the reflector what other folks do, so I
am. Looking forward to your replies.

Thanks!

N1MM+ polling abuses the transceiver.  Try setting the N1MM+ polling
speed to 50% less or 100% less.  If you see this issue with other
software, make sure the other software is not overrunning the K3
processor.

I agree, similarly with an Elad, not my choice BUT there is always the possibility some feature or other may be a popular item Elecraft can look at implementing in future FW and/or hardware.
Competition drives innovation and that is good for all parties.
Touch screen is not likely to be something I want in my radio but there IS a market for it no doubt. I just smile when I imagine a mobile with a touch screen, driving along, your contact asks you to go up 5 or something. I know I would end up either going somewhere I didn't expect or going off planet.....a bump in the road would be my downfall I reckon.

Another one for the ?Feature Request? list. The ?audio? data submode bandwidths are way too narrow out of the box. Does anyone have any idea why this is? I?m not sure I see much of a reason for any audio filtering at all other than the traditional 3K roofing filter. The downstream PC is going to do its own audio filtering at the DSP level before decoding the data anyway.

For the OP: If you like to tweak hardware, there are a number of performance improvements that can be made to the SignaLink USB hardware. Out of the box, its got a pretty high noise floor and is susceptible to noise on the USB +5 line, which directly feeds the onboard amp bias network without NO filtering. http://www.frenning.dk/OZ1PIF_HOMEPAGE/SignaLinkUSB-mods.html is a good place to start if you?re interested in better performance from your SignaLink.

Tim,

The default bandwidths are to work well with the internal decoder where 
you tune to the desired signal with the VFO,
If you are using a computer application, widen the bandwidth and let the 
software application do the decoding.

Hi Don,
While I understand that *some* of the data submodes are for decoding data on-board the radio, the ?audio data modes? are specifically for getting audio data onto and off of the radio (i.e. no on-board decoding). When in AUDIO A data submode, the radio should be passing as much of the audio bandwidth through as the roofing filter being used would allow so that the computer software can see the entire passband.

Quoting the manual:
-----
Many audio-generated data transmissions can be heard on the bands, using PSK31, RTTY, Pactor, Olivia, MFSK, JT65 and other modes. A computer, sound card, and appropriate software are normally used. DATA A mode is provided for this purpose. Unlike SSB modes, DATA A disables compression and RX/TX EQ. Upper sideband is the default.
??

DATA A mode specifically disables compression and EQ to keep the radio from dorking with the TX/RX audio. It should be disabling audio bandwidth filtering as well, as there is no valid premise for the radio making assumptions about the audio being passed. Pretty much all digital decoding software allows multi-decode across the entire audio passband. The wideband Olivia modes can require up to 2Khz of audio bandwidth. Having the radio artificially impose audio bandwidth filtering narrower than the roofing filter bandwidth is pointless and counterproductive.

I foresee Bluetooth or newer technology tablets or phone size units that
control our radio as an option to control our radios . So touchscreen
control seems like more than a fad.

There is one overwhelming reason that we'll see touchscreens:

As radios become even more software driven, we'll see more and more new 
features added (like ESSB).

The engineers and developers have to find a way to add those functions 
to existing buttons (push this button 3 times, or go to a menu, or 
something), provide a radio with blank buttons (which makes that new 
radio look unfinished, or a "stripped" version of a more expensive rig).

... or use a technology that allows buttons to be painted on the screen 
-- so the front of the radio can evolve along with the radio itself.

I'm not ready for a rig that requires a separate device/computer to run.

Probably a dumb question, but any suggestions on how to connect
counterpoise wires using the MFJ-1820T?  The loaded whip terminates in a
male BNC, which I assume is intended to connect directly to the KX3 antenna
jack.  It's not obvious to me how to add counterpoise wires???

I think some people mount them under one of the thumb screws ? but it seems to me a lot simpler to just use a large enough alligator (or blunt nosed) style clip on the end of the radial wire.  Clip it right to the metal shell of the male BNC.

Cars went through the patch where everything moved onto touch screens.
Ergonomically, that is a really bad choice. Newer cars are moving back to
having twist controls and buttons for some things that were tried as touch
screen controls. The correct answer is to have common features using real
buttons. Context sensitive buttons mixed between real buttons that are
labeled on a screen of some sort and virtual buttons.

The P(x)3 is a good example where you could use a touch screen in a natural
and useful way. I think smart phones have really advanced how we can use
touch screens. But at the same time, physical controls are really very much
easier to use. For some ideas, look at the interfaces for small aircraft
GPS/Glass Cockpit and similar systems. For some examples:
http://explore.garmin.com/en-US/general-aviation/ Each generation changes
the mix of physical controls, reassignable controls and touch screen
controls. The truth is that some things are better done on a touch screen.
Others with physical controls. And in a light aircraft, when you are in
turbulence... touch screens are really hard to use!

We are still in a bit of an experimental place, and I'm sure things will
move towards a happy balance.

In a contest, particularly a serious effort at a weekend long contest, the
constant reaching from the keyboard to the front of the rig to operate a
touch screen presents a repetitive motion problem whose outcome is anywhere
between tired and injured. This is why many people use the keyboard to
direct N1MM to QSY up or down instead of using the knob.

Some folks use things like Pig Knob, or a keypad driving macros because it
can be set next to the keyboard and used while still maintaining wrist
support for the tuning hand. For those who have already been injured by
repetitive motions at work, these simplifications may be what makes it
possible for them to operate any extended time in a contest.

It may be that part of amateur radio equipment?s future is already here,
and clearly so in avionics (i.e. the electronic display and control
interfaces for navigation, communication, and aircraft performance.)  One
major feature is the ?softkey? - a mechanical button with no exclusive
function but rather a function defined by the subsystem the screen is in.
We-all have this already in the P3, for example, which allows labelling
two rows of buttons albeit by a selection process that is tedious and very
slow compared to the better avionics systems.  And we have it in
elementary ways in certain of the display functions in the K3 and KX3.  I
can imagine a great deal more of it in amateur equipment, with a large
central display surrounded by buttons and on-screen labels changing with
the subsystem.  It would be far better and more intuitive for
configuration changes than the menu system we have now.  Even in the
relatively simple GA aircraft I?ve flown I can manage the avionics much
faster than I can operate any amateur transceiver I?ve seen. Which is a
good thing when you?re moving at a couple of hundred knots.   Compared to
touchscreens, soft keys are more accurate IMHO; but more important, they
keep the residual PB&J confined to small areas and away from the main
display.

Same ole thing...

Always, always, always rule out ALL the programs and stuff ATTACHED to the
K3 before tearing apart your K3. The vast majority of "K3 problems" have
nothing to do with the K3. I'm sure that some day some smart psychologist
will explain why we continue to do that, all evidence to the contrary.

A certain someone said to me once, "It just can't be the programs." I asked
why not. I got a hostile look. "It's the K3, it's always the K3", he said.

It was N1MM and the serial port sharing software, finally put to rest **a
year and a half later**.

I wish that psychologist would get on his horse and explain this worrisome
predilection of ours. Bet it has something to do with needing to blame
someone for our distress.

Interesting discussion.  I'm not (yet?) a touchscreen fan for radio
control, especially during a contest.

That being said (cough, cough), I am lately having some fun designing my
own touch screen interface for an ANAN-100D.  Someone came up with the
software glue to recognize and map any midi control to any CAT command for
the OpenHPSDR radios (including Apache/ANAN) and there's a $5 TouchOSC
Android application that allows you to quickly design from scratch any type
of virtual midi controller on an Android or iPad tablet.  All this has been
made possible by the Open Source nature of the software.  So instead of a
macro keyboard, I can use my 7 in tablet.

The upshot is that I might be a fan of touchscreen if they were user
configurable.  I really like the idea of users being able to design their
own front panels.

Wayne and Eric are probably already aware of the competition and working on
their own responses, but to me the UI advances I personally like are:

- visual representations of the band: panadapters with spectrum displays,
waterfalls and the like
- being able to easily QSY to items of interest on the representation.
- get rid of the ghastly external computer.

In the old old days, the curmudgeonly command to "listen listen listen!"
meant endlessly scanning back and forth with the tuning knob. Which is
perfectly fine and that's how I do it with my rigs right now, but this is a
whole new technology that can supplement that with a visual counterpart like
"use your eyes!".

So what I like in the 7300 that I think Elecraft could think about moving
towards:
- integrated spectrum scope/screen, rather than an external device
- touch-screen operation for QSY, close examination of segments, etc. 

What I don't like and would hope Elecraft would avoid in a competing
solution:
- messy implementation with all these horrible buttons around the spectrum
scope.
- horrible buttons also respond to touch, making goofs and accidental misses
at the spectrum screen your usual iPad experience when you attempt to use an
iPad for something useful. Screens and rotating things going all over the
place, making a mess. Blech!

So one idea would be a regular knob operated UI for controlling the rig
itself and a separate spectrum screen on the side, for example, that
responds to both knobs and touch perhaps. That way, fat fingers won't
accidentally reset your rig into an unusable configuration like the iPad
interface, but you do have the touch-screen capability at the spectrum
scope, where fat fingers will do the least harm and skillful use will have
the most benefit.

Anyway, some of my ideas,

The IC-7300 display has hideous resolution.  It can't even trace curves,
just a bunch of bars.  Reminds me of the original 2002 Orion sweep display.

Whatever Elecraft does going forward, please go to the highest resolution
screen that is available and have the horsepower to draw a beautifully
detailed panadapter trace.  That's why pc-based panadapters are so popular
right now.

I'm skeptical about touch screen qsy.  I can't see how you can quickly get
right on frequency.

IMHO, pandapter-centric visual tuning desperately needs a bandmap overlay
with spotted stations (whether self-spotted or cluster) indicated to be
truly useful.

Great post, IMO. One of the takeaways we could have from aviation is the
notion of cockpit resource management (CRM), part of which is the idea that
technology should reduce the workload of the pilot rather than increase it.
Or, if there is an increase, it involves a reduction somewhere else (that
is, learning to use, and paying attention to a heading bug to relieve the
pilot of turning to a heading manually, etc).

In amateur radio UI's, panadapters and spectrum scopes have a really
revolutionary potential in terms of presenting the contents of the band to
the user - you have a full visual representation of which signals are where
and a real potential in terms of QSY to those signals. 

With respect to user interfaces and touch-screen, let me make a couple
observations:
- touch-screen on a panadapter is intuitive; it's a natural way human beings
have evolved to deal with the environment. We see something in our space and
our bodies are tailor-made to reach for them with our hands, fingers etc.
- touch-screen for a menu system is NOT intuitive because a menu system
doesn't present quite the same task to the brain and body. Putting it
another way, it is my contention that a T-S interface offers no benefit to
the user over a mouse or buttons for operating a menu-driven system. 

The iOS touch-screen interface I complained about before is a good example.
When you're in an application where touch-screen is intuitive for a human
being (say scrolling and panning in a web browser) it's heaven. When you're
trying to actually operate the device with T-S it's miserable: windows pop
up all over the place, rotating cubicle things fly around and the device
goes into a catatonic state with no apparent thing on the screen you can
touch to recover it. The Big White Button at the bottom of the device is
your only resort. Horrible!

To sum my comment up: I think it's easy to overreact with touch-screen
technology and try to use it for _everything_: not just the applications
where it's great, but also where it doesn't help or even hinders the use of
the device (re: the distinction I made above). 

So going forward with amateur radio, I think T-S technology should be
carefully considered and not done with the Hog Wild method Apple chose for
the iOS interface. That's where the IC-7300 goes overboard, for example, as
I alluded to in my other post: it overreacts and attempts to use T-S for far
too much functionality in the device. 

If Elecraft goes down that road, I would hope for a more balanced approach,
one that's more suitable for the way humans respond to the environment, when
it contains both natural (i.e. spectrum scopes) and unnatural (i.e. menu
driven systems) items.

yep, I totally agree. This would be a TBD item for a UI designer, IMO: to
what degree do we actually replace the tuning knob with touch-screen QSY? Do
we make it capable of just getting into the neighborhood and then the user
has to fine tune with the tuning knob? I.e. a kind of dual-capability
approach. Or do we make it able to do exact tuning, completely replacing the
tuning knob?

Probably one of those things that would have to be developed on a
trial-and-error basis, IMO. One of the hazards of very powerful technologies
- the club can be just as easily turned on _you_ as on your good intentions
LOL.

Use one of the KX3's thumbscrews. We relieved the paint on the chassis at these points so you can use them for counterpoise wires or ground.

I'm always terrified of losing the thumbscrew in the grass. I wish MFJ made
these with a built-in right angle and a binding post, or even just a bolt
and a wing nut, at the base.

I have a THP HL-1.2KFX that I used before the acquisition of my K3. It is a reliable and resilient amp and I have had the ALC connected to the K3 for a year. However
I tend to take Don Wilhelms advice and there have been times when the ALC and SWR inputs to the AMP?s logic seem to fight each other, so I just disconnected
the ALC and will report any issues?.silence = happiness.

I mourn the the shutdown THP after the earthquake/floods. It was a terrific company with a lot of great products with leadership in the mould of Elecraft.

Easily solved. Method One: Put spade lugs on one end of the wire(s) that 
you rig for counterpoise, loosen the thumb screw, and slide them under.

Method Two: Put a spade lug on a short piece of wire, slide it under the 
spade lug, put a single Power Pole on the other end. Then add Power 
Poles to one end of the counterpoise wires.

I use method two. In the shack, it's used to bond the KX3 to the rest of 
my gear. In the field, it's easy to rig for a counterpoise.

I also carry a BNC to Pomona (dual banana) adapter, which makes it easy 
to rig wires to the KX3.

Bill,
Your comment is appreciated. I am in your camp but we are a bit older and happy with our
current campfire. Younger hams and new hams might be very engaged with a touchscreen
interface. The ?over $8 K? product managers seem to have peaked lately in their ?plethora of knobs"
approach to the ?mature ham market?. Elecraft is still the primo innovator with regard to performance,
packaging, reliability and clever circuit design.

Message-ID: <201603291701.u2TH1VH1007470@mail40c28.carrierzone.com>

LD,

That is why it was so hard to pass the CW tests back in the 1950's 
taking before the FCC because the test did not have any real 
words.  The entire 5 minute code test was five random character 
groups, not all of which were letters or numbers and you had to have 
one minute perfect copy to pass.  I never managed to pass at the FCC 
in Detroit with the unsmiling stern FCC employees that looked like 
they were FBI ready to haul you off to Cuba or somewhere? ;-)

So imagine my pleasure taking my 13wpm at the Anchorage FCC office in 
1982 with happy friendly faces and copying samples of an actual QSO 
with real words and only having to answer seven multiple choice 
questions about the test correctly - absolutely no comparison with 
the CW "inquisition" of the 1950's.

BTW I did get to the point that I recognized common words like "CQ", 
"de", "73", "name", "RST", "QTH", etc.  They became words in the CW 
"language".  Too bad CW isn't sent in Latin; I took two years of that 
in HS <laughter>.
Only good that did me was understanding the priest at a Catholic Mass 
back in the days they still spoke in Latin.  Of course I can pick out 
a few words in Spanish and French and several other languages that 
have Latin base (like English) - <more laughter>.  Pretty hard to 
copy CW in Yupik Eskimo.

Good points about CW becoming a language.

That would explain why, for example, your copy speed will drop (sometimes
dramatically) when the content is blocks of random letter/number groups
instead of plain language, or if you're reading the mail on a QSO in another
language like Spanish or German (and you don't speak those languages).

Message-ID: <201603291713.u2THDfiJ012115@mail42c28.carrierzone.com>

I thought the best way to drive an amplifier was to increase drive 
until output no longer increased proportional to input; eg output 
increases 3-dB with an 3-dB increase in drive is linear.  Isn't the 
point the increase drops 1-dB the upper limit?

That is how I determine best drive level on VHF linear amps.  Most 
folks run up drive until they reach saturation (no change in output 
with increased drive) and then operate SSB there.  No wonder their 
voice peaks are cut off causing splatter.  BTW high speed CW should 
not be run at saturated power, either.  CW actually has bandwidth 
though at 5wpm probably not measurable <ha ha>

ALC was a good concept that never worked very well (negative feedback 
gain control).  ALC meter on the K3 is useful for setting audio drive 
just to the point ALC begins to act (four bars with 5th flickering). 
But I guess all of you know that - right?

Excellent points, IMO. I took both types of code tests. For my novice in 1973
when I was 10 years old, it was the random groups at 5WPM format. IIRC, I
achieved the 1-min-solid-copy requirement by some miraculously slim margin.
It was something like 2 or 3 characters and I remember being extremely
relieved and elated at the accomplishment. 

For the Extra, years later, it was when the content was a regular old QSO,
so I had virtually completely solid copy of the whole thing; the written
test was nearly my downfall in that case (I passed with like 71% or
something). 

Finally, IIRC, licenses like the commercial radiotelegraph license had even
more comprehensive requirements - something like 5 minutes of random groups
at 20wpm, 5 minutes of plain language at 25wpm, or something like that,
depending on what class of license you were going for. Pretty tough! 

So yes it seems to be well established that plain language is quite distinct
from random letter/number groups with respect to copy speed. And it was
tested accordingly, or at least in my opinion it was. 

Fortunately, now that CW isn't required at all has seemed to, ironically,
started a revival in CW. The CW portions of the bands do seem to still be
more sparse than the SSB portions, but they're still there....

I may have missed something in this discussion but I question what is different from using a touch screen or the buttons on the radio as we have now?  I operated a considerable amount of time in the WPX SSB test last weekend using a K3 and about all I ever changed was the tuning knob and the width control.  And maybe he NR and NB a couple of times. Using N1MM+ I did not even need to change bands using the radio controls.

WRONG! CW speed has NOTHING to do with bandwidth, which is determined by 
RISE and FALL times of the keying waveform and distortion in the RF stages.

I strongly agree that amplifier output power should NEVER EVER be set 
using AGC. It should ALWAYS be set by setting drive power for the 
desired output, but always staying below the power level that increases 
amplifier non-linearity (distortion).

The use of AGC to set amplifier power has been considered a bad thing 
for at least 35 years -- the operating manual for my Ten Tec Titans says 
not to use it that way. If you look at the schematics (in the manual) 
you'll find K4XU's initials on them. Thank you, Dick!

The ONLY good way to use AGC is to protect the amplifier when something 
fails in the antenna system (by reducing drive from the transceiver). 
Yes, some rigs produce power spikes at the beginning of a transmission. 
Those are bad rigs, and have no business being used to drive a power 
amp! If you want to run an amp, buy a REAL radio. :)

Interesting discussion.  I'm not (yet?) a touchscreen fan for radio
control, especially during a contest.

That being said (cough, cough), I am lately having some fun designing my
own touch screen interface for an ANAN-100D.  Someone came up with the
software glue to recognize and map any midi control to any CAT command for
the OpenHPSDR radios (including Apache/ANAN) and there's a $5 TouchOSC
Android application that allows you to quickly design from scratch any type
of virtual midi controller on an Android or iPad tablet.  All this has been
made possible by the Open Source nature of the software.  So instead of a
macro keyboard, I can use my 7 in tablet.

The upshot is that I might be a fan of touchscreen if they were user
configurable.  I really like the idea of users being able to design their
own front panels.

I'm not the one here with the most money, 
I'm absolutely positive of that, but that 
said; I can buy any rig I want and the 
dollars spent wouldn't in any way affect 
me, or anything I do in the future. 

I just bought a K3S because of the many 
things it represents but I'm not a martyr 
to buy USA when something else is better 
or, buy something wonderful that is 
software based only like the Flex 6700; I 
bought the K3s because to my discovery, it 
is the finest radio out there. Yes, this 
is the Elecraft reflector so most of us 
are already on board but I bought this 
radio (I upgraded from an updated K3) 
because it is to me, the pinnacle of 
today's equipment.

I just worked the VK0KE on 160 last night. 
I honestly, to God do not think that any 
radio I have ever owned before, save the 
K3 with the updated synthesizer, would 
have heard the incredibly diminutive 
signal that I heard reply to me. I was the 
first NA station to post them in the 
cluster yesterday and that is because of 
the quality of this radio. The K3s Rocks.

IC-7300 Video... Pffttt.

No, because even the best rise/fall waveform has SOME harmonic content, 
and CW speeds of 10,000 WPM have no practical meaning. But you CAN 
occupy extremely narrow (a few Hz) bandwidth with a steady carrier, 
because there's nothing to excite IMD. Bandwidth would be greater than 
that only to the extent that the carrier is modulated by power supply 
noise or phase noise. And, of course, any distortion in the RF chain 
will produce harmonics.

Well, 5 replies reported no problems with coil wires breaking during 
transport, while none reported a problem.  I guess with all the zillions 
of K3's etc. traveling around, we would know if there were problems.  
I'll let you know in a few months what a few thousand miles by bicycle

The relationship of bandwidth and speed is that for given rise/fall 
times, increasing speed will reach a point when the code elements blur 
together.

So you need more bandwidth for super high-speed CW because you need to 
shorten the rise and fall times. But the occupied bandwidth doesn't 
change as you vary the speed.

The K3's keying waveshape and rise/fall times (the shape is important, 
not just the time) are good for far faster CW than I can send!

OT... but my mother, back in 1942, after 
divorcing her abusive Ex (One of the main 
architects of the Golden Gate Bridge), 
bicycled by herself from Philly to Key 
West, by herself, took a ferry to Cuba, 
bicycled around the island for a month 
before returning to the mainland to take 
the train back to Philly.

For those of you on Facebook, here she is 
in 1942 with her bike, on the Tamiami

For me, even if touch-screen UI's were written for old people like myself, hi
hi, I still think its a technology in its infancy. 

The infantile part of it being primarily in its application, not so much
just the mere fact that TS technology itself new and still in "1.x"
revisions. When Garmin came out with touch-screen UIs on their aviation GPS
products is when I recognized that the T-S train had skipped off the rails -
I wondered if anyone at Garmin's aviation products division had ever even
flown in a light aircraft before? And Apple continues to threaten to go
all-iPad with every release, though I suppose if sanity could return
somewhere Apple might be the most likely first place for it to do so.

In amateur radio, my opinion is mixed. I can see myself having fun with T-S
on a panadaptor, but the smile kind of fades from my face when thinking
about using the radio in general on a greasy thumprinted, fussy screen with
windows popping up all over the place.... 

All things being equal, though, I prefer knobs on a radio and not having to
wash my hands with toilet bowl cleaner before I use it hi hi. Like I said,
maybe a separate screen for the T-S spectrum scope, but everything else
relegated to good ol' knobs hi hi.

The standard word "paris" has 48 elements.  That makes the baud rate
for CW (48/60) x WPM or 0.80 x WPM.

ITU defines the "Necessary Bandwidth" for CW as 3 or 5 times the speed
in bits per second (baud rate) where 3 x is for "non fading circuits"
(where the waveform does not need to be so "sharp") and 5 x for "fading
circuits."    See:
     http://http://life.itu.ch/radioclub/rr/ap01.htm part B.
The same table is found in Title 97, Part 2 of the Code of Federal
Regulations (FCC Rules) as ?2.202(g)

The constant 'K' sets the minimum bandwidth needed/occupied for the two
recognized cases.  Occupied bandwidth in excess of K=5 (or 400 Hz for
100 WPM) would be unacceptable due to improper keying waveforms or
distortion in the RF stages.

In my mind, I have a totally different picture of this.

I don't see a panadaptor, or windows, or pop-ups.

I see a front panel that looks very much like a KX3 or a K3, with 
buttons drawn on the touch screen.

I see some ability to "turn off" buttons that I would never use, and 
make other buttons bigger.

Mostly, I see a way for Elecraft to add a button for some whiz-bang new 
feature, instead of having to squeeze more functions in without being 
able to add a button.

Message-ID: <A0F6481C-4EA9-4125-934C-8E313DF439D0@gmail.com>

Hi folks,
I know this has been asked and discussed before but I can?t seem to get a handle on a clear-cut answer ?

I am going to do a SSB NPOTA (National Parks on the Air) activation with my KX3/KXPA100/PX3 on battery power. It has been in the works for a while with a special use permit required by the NPS.

How much battery capacity do I need if I want to run full 100 watts? For planning purposes, I am assuming a 6 hour activation with a (highly optimistic I know) 60 QSOs per hour.

The PX3 will be powered by a separate LiFePo 4.8 aH battery, it will do just fine. My concern is the amount of draw I will need to last the 6 hours. With an inline (Hobby King) HK-010 Power Analyzer, I see a max current (KX3/KXPA100 combo) of about 8 amps and about 80 watts during a QSO. The QSOs varies between 50-80 watts on transmit.

I also know that once I am spotted, I can drop the power down to maybe 75-50 watts to save some battery juice.

I have 2 12v-18aH SLA batteries at the ready, am I woefully underpowered? If you have any real-world experience or tips, it is most valuable and appreciated. You can contact me offline at dave dot esquer AT gmail as well.

Thanks,
Dave, K6WDE

I think you'll draw a lot more than 8A at 100 watts. 

Also note that to get 100 watts from this setup will require a bit more than 14 volts I think. I ran my PS at 14.5 or better to make it. YMMV!  

You're gonna get a lot responses on this query, so be prepared. 

Your best friend here is going to be AMPHOURS. The more you have the longer you'll be able to keep the voltage drop down. When the voltage drops too low the KX3 will drop the power. You might consider starting st 75 watts and drop a bit when the pileup gets going. 

Where at you going. And have your spotters note the park or Unit ID.

Councilor: LOL if you are looking for precise information from imprecise data. Best I can do is a WAG.  If you take your ah rating say 36 and multiply by the battery voltage say 12, we have 432 watt hours. Divide by 2 to account for efficiency losses and we have 216 wH and finally divide by your transmit draw 80 watts and we have  2.7 transmit hours. Does this help? Remember this is a WAG (Wild Assed Guess).

Subject: [Elecraft] Battery requirements for NPOTA activation with KX3/KXPA100

Hi folks,
I know this has been asked and discussed before but I can?t seem to get a handle on a clear-cut answer ?

I am going to do a SSB NPOTA (National Parks on the Air) activation with my KX3/KXPA100/PX3 on battery power. It has been in the works for a while with a special use permit required by the NPS.

How much battery capacity do I need if I want to run full 100 watts? For planning purposes, I am assuming a 6 hour activation with a (highly optimistic I know) 60 QSOs per hour.

The PX3 will be powered by a separate LiFePo 4.8 aH battery, it will do just fine. My concern is the amount of draw I will need to last the 6 hours. With an inline (Hobby King) HK-010 Power Analyzer, I see a max current (KX3/KXPA100 combo) of about 8 amps and about 80 watts during a QSO. The QSOs varies between 50-80 watts on transmit.

I also know that once I am spotted, I can drop the power down to maybe 75-50 watts to save some battery juice.

I have 2 12v-18aH SLA batteries at the ready, am I woefully underpowered? If you have any real-world experience or tips, it is most valuable and appreciated. You can contact me offline at dave dot esquer AT gmail as well.

Thanks,
Dave, K6WDE

Those of us who have aging, shaky hands don't even need the turbulence, ?our own brains conspire to make touch screens difficult to operate. ? The "soft buttons" like the P3 and PX3 have work great, though. ?They allow the finger to touch the button without activating it so you can tell that you are pressing the right spot.

A couple of airline crashes have been blamed on the pilots being unable to
touch the right spots and read the "gages" in modern all-glass cockpits when
the aircraft was experiencing severe turbulence or vibration from engine
problems. And they happened while one pilot was able to concentrate (as much
as possible) on the display while the other one was flying the plane. In one
instance it led to the crew shutting down the wrong engine which led to a
crash after they discovered the error too late to restart the good engine
before running out of altitude.

I've looked at this too, given that I'm /P almost 100% of the time now and
have considered various QRO options. Unfortunately, I've yet to find a QRO
solution that doesn't involve something semi-permanently mounted in my
truck. Either a deep-cycle AGM or a high capacity LiFEPO4 in the spare
battery tray under the hood with long heavy cables is about the best I've
been able to come up with.

If I keep it at 10 watts or less, though, I can actually carry it a short
distance (and of course its easily transportable in the vehicle). My K3 and
K3S, for instance, will run a good 4 or 5 hours on my 9AH AGM batt, though
less than that with a lot of transmitting. The K2 would run all day on the
same batt....

So that might be required in your case too? Eg. a YellowTop 12V deep cycle
in the vehicle or an equivalent LiFE 12V... Sorry, I know that's not much
help, but I'm kind of in the same boat hi hi.

SSB is low duty cycle. Even if you have processing cranked way up, with 80 watts out peak, your average power won't be any where near this level. And you do have to stop talking and listen, fetch a beverage, visit the nearest shrubs, right? :)

I think you'd easily do 6 hours with what you have -- and have a good bit of battery left over.

In the 1950's the U.S. 2nd class commercial Radiotelegraph license exam
required 20 wpm sending and receiving. Receiving was 5 character random
groups that included all punctuation and most of the special characters you
see above the numbers on a keyboard. After 6 months of sea duty as an
assistant radio officer, one could apply for a First Class license that
required the same but at 25 wpm. I don't recall how long we had to copy,
just the elation LS experienced at passing, Hi!

In our work we had to have excellent character-by-character copy, usually
pounding keys on a mill. Contesting is a bit like that except that in a
contest one has a planned format and very short message as contrasted so,
say, copying press (news) for half an hour at a time. 

I'm not surprised at the speeds one hears in contests. When rag-chewing,
however, I seldom find stations running more than 20 wpm, often much less.
And I often just "read the mail" in my head listening to CW rag chews while
puttering around the shack. 

IMHO, the different uses for CW lend themselves to different learning
techniques. I have met good, competent contest operators completely unable
to have a QSO that is not a contest exchange. They simply cannot think
conversationally at a key or paddle. On a keyboard they often revert to a
brag tape and must QRT when it runs out. And of course, everyone seems to go
through a bit of a learning curve to copy CW in their head.   

After all these years 99% of my operating is still CW. I joke that I spent
so much time learning CW that I am determined to get as much value from the
effort. (It's not entirely a joke, Hi!)

Excellent points, IMO. I took both types of code tests. For my novice in
1973 when I was 10 years old, it was the random groups at 5WPM format. IIRC,
I achieved the 1-min-solid-copy requirement by some miraculously slim
margin.
It was something like 2 or 3 characters and I remember being extremely
relieved and elated at the accomplishment. 

For the Extra, years later, it was when the content was a regular old QSO,
so I had virtually completely solid copy of the whole thing; the written
test was nearly my downfall in that case (I passed with like 71% or
something). 

Finally, IIRC, licenses like the commercial radiotelegraph license had even
more comprehensive requirements - something like 5 minutes of random groups
at 20wpm, 5 minutes of plain language at 25wpm, or something like that,
depending on what class of license you were going for. Pretty tough! 

So yes it seems to be well established that plain language is quite distinct
from random letter/number groups with respect to copy speed. And it was
tested accordingly, or at least in my opinion it was. 

Fortunately, now that CW isn't required at all has seemed to, ironically,
started a revival in CW. The CW portions of the bands do seem to still be
more sparse than the SSB portions, but they're still there....

I think it's directly proportional to the amount we spend on said device.
If we spend a lot for it, the the expensive doo -dad must be at fault 
when things hit the fan.
Couldn't possibly be the software. N1MM+ is a great piece of software 
used by thousands and the price is free, gratis, etc....It's not

My memory is 16 WPM code groups and 20 WPM plain text for the Second
Class.  The one year at sea was for the endorsement permitting  the
person to be the sole operator on cargo ships.  The requirement to sit
for the First Class exam was one year or more experience handling Public
Correspondence (message traffic to and from commercial ship or shore
stations excluding most military experience).  Passenger ships required
two or more operators, one of whom had to hold a First Class license
acting as "Chief Operator".

The code requirements for the Second Class have been carried over for
the "combined" lifetime Radiotelegraph Operator License.  The FCC will
no longer issue  First Class Licenses because Manual Morse is no longer
required for safety and distress traffic in the Maritime Services now
that the satellite and SSB-based GMDSS is in operation and there is no
need for a "Chief Operator" on ships..

I finally got my Second Class before the "cut-off", one of the last 8 so
issued.  It gets renewed only once in 2018 and then it goes "lifetime"
losing the Second Class designation.

So... this may be too far OT and forgive me for being ignorant, but I'm
genuinely curious. Is Morse used at all anymore in any commercial or
military enterprises? Or is amateur radio "it" for CW these days? I honestly
don't know if we're the only ones left using it on planet Earth or not....

Ummm ... not exactly true but not exactly not-true either.  Occupied BW 
is a function of bit-rate [well, technically, number of signal 
transitions in a unit time, but they're closely related].  Fairly basic 
physics ... or I guess that's information theory now.  The faster you 
send, the wider your signal will be, guaranteed, you can't escape it. 
Like trying to drive faster than light, discarding angular momentum, or 
resigning from Linked-In.

Waveshape also affects occupied bandwidth, although the amount it 
increases the BW carries no information ... except for the useless fact 
that the dude with huge key clicks is still up there 15 KHz.

At "normal" CW speeds, aka D4C, the BW increase due to speed is hardly 
noticeable. With poor wave shaping, it is VERY noticeable, and 
information-free.

I may be wrong and it wouldn't be the first time but I think the Navy 
still teaches pilots Morse code.

As far as I can tell, Morse is entirely a hobby now. Maritime radio stopped monitoring Morse on 12 July 1999. I did some searches and I don?t think the US military offers a Morse skill rating now.

You can make a living blacksmithing, but not with Morse code.

This takes nothing away from Morse as a hobby. Or from blacksmithing ? my father was an amateur blacksmith.

As a private pilot I fly with a Garmin GTN750 touch-screen GPS NAV/COM in a 
Cessna 182. Its powerful and quite intuitive to use, even in turbulence. (They 
included ridges along the four screen sides when needed to steady your hand.) It 
actually reduces the amount pilot load and time spent looking inside the cockpit 
when used properly - Though you can certainly abuse it dangerously if you treat 
it like a video game and forget to look outside the cockpit..   I wouldn't go 
any other way now.   (And I came from a full-on knobs based flight environment 
prior to that.)

There are great touch-screen avionics implementations and horrible ones. The 750 
is a good one and world's above many others.

I think for future ham radios and similar product designs, what will be 
important is meshing the correct balance between traditional hard knobs and 
buttons with unique touch-screen features (display and input). The overall goal 
should be to balance the user interface between the touch-screen and 
knobs/buttons for ease of use without unintended confusion while adding unique 
touch-screen display and easy to use input features.

As a side note - I use the remotehams.com free remote software with the 
K3/0-Mini and a laptop to remote my home K3S, KPA500 and Rotor. Interestingly, 
the little h/p satellite 360 convertible laptop/tablet has a touch screen, which 
I use for many functions like rotor control, amp control/status etc, but I like 
it combined with the K3/0-Mini's knobs and display for regular intuitive use, 
versus using it only for 100% computer based remote control.

Hi Gerry,

If I'm using the rig HT-style (/PM, or pedestrian mobile), I just connect the whip directly. The KX3's BNC connector is rigidly attached to the right side panel, with a D-shaped bushing so it can't rotate, and a flexible wire from the BNC's hot lead to the PCB. So you won't hurt anything by doing this. Any 48" long telescoping whip with a base loading coil and BNC will work, though as I mentioned, I'm partial to the MFJ 18xxT series.

For picnic-table-syle operation, I've been using the whip with a tiny home-made tripod. It has two female BNCs: one at the top for the whip, the other at the bottom at a right angle so it can attach directly to the radio. The radio connection can use either a double-male BNC adapter or a length of coax. The height is adjustable to match the height of the BNC on the radio.

The tripod has three legs that fold up and out of the way, resulting in a unit that's less than 6" long and 1" in diameter. Weights only a few ounces.

If anyone besides me is interested in the tripod, maybe we'll make it into an Elecraft product :)

73,
Wayne

Manual Morse is still alive in the Maritime Services through Public
Coast Station KSM, the former RCA Coast Station KPH,  with receivers in
Point Reyes, CA and transmitters in Bolinas, CA.  It is owned by the
National Park Service and operated by the Maritime Radio Historical
Society with properly-licensed operators.  We operate on weekends, on
genuine restored coast station equipment, and there are still several
vessels that use Manual Morse for traffic.  We accept message traffic at
no cost - we're funded by grants from the Park Service and member
donations.  And we still keep "Silent Period" watch on 500 KC as in the
"good old days".  We also operate a ham station on several HF bands  -
at full legal power - licensed as K6KPH but using maritime calling and
traffic procedure.   See:  www.radiomarine.org

The military still trains a small cadre of Morse intercept operators -
now rated as Crypotologic Technicians - because "the others" still use
Morse for various purposes and we need to know what they are up to.  It
is not used for tactical or command communications. See:

Ron, this is what I recall from the FCC commercial radiotelegraph Morse exams:

Third Class and Second Class:
20 wpm plain language receive for five minutes, perfect copy required for 100 consecutive characters (one minute).
20 wpm plain language send (straight key use mandatory) for up to five minutes, perfect sending required for 100 consecutive characters (one minute).
16 wpm random character groups receive for five minutes, perfect copy required for 80 consecutive characters (one minute).
16 wpm random character groups send (straight key use mandatory) required for up to five minutes, perfect sending required for 80 consecutive characters (one minute).

The test for First Class was as described above at 25 wpm plain language and 20 wpm code groups.

Written exam elements 1, 2, and 5 were required for Third Class.
Written exam elements 1, 2, 5, and 6 were required for Second Class and First Class.  Element 6 required some short answer and schematic drawing.

Everyone generally took the exam for element 8 Ship Radar as well.

I passed the Second Class exam almost 40 years ago, but my old study books for the exam indicate that the tests listed above were in place even before WWII.  AFAIK, the only change occurred in the early 1990s when the FCC began giving credit for all of the above if the candidate held an Amateur Extra license.  That, of course, wasn't even remotely equivalent...I guess the FCC just got lazy.

I took several ham Morse exams at the FCC in the late 1960s and early 1970s.  Contrary to some claims otherwise, I do not ever remember the 13 wpm test being random code groups on a ham exam.  That is far more difficult than plain language to a ham new to Morse.

A good practical capability to function at 25 wpm was sufficient for starting a merchant marine radio officer career.  Until it all disappeared on 12 July 1999, the MF Maritime Morse band (410 to 535 kHz) was the most magical spot in the entire radio spectrum...especially at night!

I got solicited by the Radio Officer's Union in 1991...there weren't enough radio officers to man the US-flag merchant vessels that got re-activated after Desert Storm.

What I really regret is that during my US Navy days there was nothing so small and capable as the Elecraft K1.  I could have had a fine time *ashore* with a K1.

I know about KSM, but that isn?t a commercial enterprise or even a nonprofit full-time job.

My dad volunteered as a blacksmith some weekends at the old Texas exhibit at the Fort Worth Zoo. But it wasn?t a job. He really enjoyed it.

Message-ID: <r470Ps-10114i-2B41014D52D9453FA68A7CA879289A48@Williams-MacBook-Pro.local>

In a desperate attempt to make this subject at least vaguely on 
topic, note that future CW use is important to the future 
requirements for ham radios. If new hams aren't interested in 
CW, then good support for CW will become less important, 
particularly as older ones leave the hobby.

There are a couple of things which give me hope for the 
continued use of CW:

CW is the easiest mode to use for DXCC. Between the large number 
of stations active on CW, and CW's ability to work in bad band 
conditions, I think it will continue to attract users. Digital 
might be a contender for bad conditions, but it seems to me the 
QSO rate is always slower for Digital vs. CW.

The number of licensees in the US continues to climb in all 
three license classes. Even if we assume that all the 
technicians are only interested in VHF/UHF FM for emergency 
services use, we still have growth in generals and extras. These 
people will be using HF for contesting, among a myriad of other 
uses. Many contests have incentives for CW in their scoring systems.

Gary,
   Congrats on working VK0EK on 160M with your K3S. Yes, it is a great radio. I'm using the K3 with the synthesizer upgrades made to both main and sub receivers. A few weeks ago I worked a super pee weak 4S7BRG on 40M for #313 on that band with 100 Watts and a wire antenna. When the rare VP8STI (So. Sandwich) and VP8STG (So. Georgia) DXpeditions came on the air, my barefoot K3 again did its thing, adding Topband countries #226 & #227 to my 100 Watt 160 Meter totals. 

The K3 with its 200 Hz roofing filters, DSP further reducing the bandwith to 50 Hz, then the APF further tightening the BW to a sharp 5 Hz peak made it possible to hear those weak signals through my local noise. Having K3S transceivers on the Antarctic end of the path sure helped those 160M QSOs make it into the K1HTV log.

Now I need to focus on working VK0EK and FT4JA for even more Topband DX with my K3, a great radio!

because it is to me, the pinnacle of

I just worked the VK0KE on 160 last night.
I honestly, to God do not think that any
radio I have ever owned before, save the
K3 with the updated synthesizer, would
have heard the incredibly diminutive

first NA station to post them in the

the quality of this radio. The K3s Rocks.

I took 3 FCC code exams: the 5wpm for my novice in 1973, and years later, the
13wpm for the Advanced and the 20wpm for the Extra. But ironically, I think
the FCC removing the code requirement was a good thing for CW in amateur
radio. Now that people aren't forced to learn it and have to use it, and
potentially develop a bad taste in their mouths for it in the process,
they're more attracted to it as another activity they can pursue in the
hobby. Just like the digital modes and so forth. The FCC no longer practices
"mode discrimination" and amateurs are free to use whatever mode they like.

I've heard it said that CW usage has actually gone up since the CW
requirements were dropped, and I believe it. The lower end of 20 meters is
essentially unusable when a CW contest is going on, or at least it's good
thing I have rigs like my K's that can handle 800 S9+30db sigs every kc in
the band hi hi.

So to bring it back around to Elecraft, I should think the incentive to
continue to support strong CW capabilities in the K rigs will continue to be
there for quite a long time....

I was about to reply to a couple of posts on the UI topic when I read
Eric?s post (below), which makes a point I would underscore.

Since many of us (not surprisingly) share aviation and hence avionics
experience as well as amateur radio, that experience may be useful in
reflecting on the topic of UI for amateur gear. As Eric implies, and as LS
also points out, the question is not either-or.  There are some functions
for which soft keys are better than layered menus, and those better than
dedicated buttons and knobs, and those better than or worse than touch
screens.  For example, I think that during critical phases of flight I
would not want to replace the tactile feedback of a throttle lever with a
screen-based input; I like having the gear lever feel like a gear lever
when I grab it; and while this one I might be willing to change, I think a
flap control should feel something like a flap.  But navigation is
cerebral rather than tactile, and for that an intuitive layer of soft keys
seems just right.  On the other hand, if I need to kill the strobes
because I?ve just entered IMC (clouds, to the earthbound), I?d like to
stab at a known, dedicated, and unprogrammable button that I?ve mentally
marked IF YOU CAN?T SEE, PUSH HERE RIGHT NOW. Point - touch screen isn?t
better or worse than any of the alternatives.  It?s either better or worse
for some functions than any of the alternatives, but not for others.
Maybe VFO A knobs are like flap controls?   My point in raising the
experience of avionics was to say first, that that field seems a bit ahead
of the amateur radio gear field in ergonomic design of similar systems;
and second, that it shows that design choices shouldn?t be driven by
global preferences.  No surprises there, eh?

As far as I know, touch-screens cannot be easily be navigated by 
unsighted operators.
How would touch-screens be implemented in keeping with Elecraft's 
promise to allow handicapped operators full access to the operation of 
the Elecraft line of products?

USN still has the CTR rating and teaches Morse Intercept Ops at Corry 
Station, Pensacola, Florida.
http://www.navy.mil/submit/display.asp?story_id=92864


Prior to being located at Corry,  Morse Intercept Ops (CTR's) were 
trained at Fort Devens, MA.

I attended Manual Morse Radio Op School at NTTC San Diego.
Most students at the time came from the SEAL community and/or Marine 
Recon BN's, with the exception
of a few of us Marines who were shipping over into the SIGINT/EW MOS's...

I have experimented with LiFePo4 batteries feeding KX3/KXPA100 in contest 
environment where duty cycle is about 50% for TX. For SSB the current draw 
is a bit higher then for CW. 25Ah battery lasted 4 to 4.5 hour with 100 W in 
the beginning and dropping to 50-60W out in the end of the cycle. For SLA of 
the same capacity you will probably have  half of that time. With 2x 60W 
solar panels added to the mix I get between 6 to 8 hours in semi sunny 
weather. I have ended up with a pair of LiFePo4 25Ah each (about 2 Kg each) 
which allow full day of operation. Again if you use SLA instead of LiFePo4 
you will need at least 100 Ah.

Yes, but that's RX bandwidth, VERY different from occupied bandwidth. 
The issue is RX bandwidth is the TIME (phase) response -- every change 
in amplitude is accompanied by a change in the phase response, that that 
phase distortion (remember, phase is time) blurs the code elements 
together.

You need more RX bandwidth, for the reason described above.

> But the occupied bandwidth doesn't change as you vary the speed.

Right. Occupied bandwidth is your "footprint" on the band -- how much 
your signal is spread out.

There were no responce to the initial message so I post it again:

I have both K3 and KX3 and I sometimes use them outside in a field
operation. Here in Russia we have one funny QRP contest called  "Frost-red
nose" where extra points are given for low temperature environment during
field operation. The contest happens in January when in some places
temperatures can be down to minus 30 C. I did not find temperature
requirements for K3/KX3 in the specs. Can somebody give me a hint or may be
share own experience. What would be the lowest temperature where the rig
will still perform adequately?

Unfortunately the guys who wrote the rules failed to understand the

2003-4. Henry is a VERY smart guy, one of many who came out of Bell Labs.

You should directly contact the Elecraft factory for this. However, as I recall, the K3 and KX3 are designed to operate over an operating temperature rating: 0 ? 50 ?C.

This may not be applicable to the K3 but I have used the K2 below 32 F.  
My K2 has the 100 watt amp with a built in fan.  The fan got confused 
and stayed on.  The algorithm to adjust the fan speed did not understand 
a negative Celsius temperature.  With the fan blowing my fingers got 
pretty numb and kept sending more dits than desired :)

Re: ? "I may have missed something in this discussion but I question what is different from using a touch screen or the buttons on the radio as we have now?"

On screen buttons activate as soon as it is touched. ?Hardware buttons allow the finger to touch the button and give the brain an instant to verify that you have indeed touched the button you intended to touch, after which you can apply the pressure to activate it. ? The difference is huge when your hands shake, or g-forces are moving them around. ?THAT in a nutshell, is the difference between a touch screen and hardware buttons.

But even if the RX bandwidth is wide enough that there is negligible 
distortion, you can't distinguish dits that are 5 ms long if the rise 
time is 2 ms.

Hi all.
I have nothing against touch screen, out of the fact that sometimes is
... touchy.
The responsiveness of the virtual buttons should be much more the the
one of physical buttons or, too old to die, command lines. Touch
screen need to give you a faster and accurate response even if the
background HW/SW is not so responsive or ... touch, touch, touch again
and again. The smart phone teach. That is more massively in use than
other touch mechanism. However, this is only one line for the whole
book, that is not all written at today.

On the other side I would simply do not care about a touch screen if
there are enough CAT commands and there is plenty of user defined
macro button on any logger.
As an addicted to RTTY I see where the action is: the screen of a
computer or two, usually large screens, and my ears, when in needs
i.e. RIT, SO2R and other cases. The action is not on the radio until I
recognize something wrong on usual advice devices. Those need to be in
plain view almost every time.

Touch screens are, maybe, a good selling point for smallest radio. (A
smallest radio isn't also by default the one with the smallest
weight.) On the other hand, the touch screens  will be a good
engineering selling point when to cut down physical buttons/encoders
project expenses. I hope only that all the this engineering that will
change our habits will not change in any way what is inside a radio:
CAT vocabulary or on a wire commands, external commands abilities and
capabilities..
KIS is on another planet, maybe universe of a drill down sequentially
of 2 to 4 visual masks where to find what to touch that buried
function. Often physical controls offers ... control ... on a tip of a
finger: I do not have to look it all that, just go there, check, and
move onto with a second click and drive it where I need. I would not
like to play another windows game to do it as often as it goes.
I.E. the CLEAR RIT is better on a macro and on a single push button
than two screens away. There is, two screens away from the main, as a
toggle button ... but it is toggle of what "two screens away from the
normal screen view". Even when that needed function is reached and
used, what will happen on the next TX or after a so-called sub screen
timeout? The screen will fold back on the main screen or will stay
forever there? Until the PA instruments or lights would tell me a
deadly end for a not controlled Pout, SWR or another parameter ...
That is, summarizing, poor engineering practice and sometimes it is
not avoidable. Even on strict coupling of the same brand boxes.

I really do not know how is made the IC-7300 or how it perform. It
will be a pleasure to discover it all. However, I am not in a hurry,
nor expecting that much.

I am still saving to transform my two K3, pragmatically, on what will
be the most usable and feasible with the newest parts. This would be,
when it could be, more than any touch screen. For other
characteristics of other machines: I will be at the window.

Changes are often a need, even if not greatly requested, but not all
changes are improvements.
Often changes are made in steps, sometimes real advantages are
deployed in the last of those.

Wow, a touch screen. Wow? Come on, it's just an interface between man 
and machine.

Just some ( and I mean /some/) thoughts:

A touch screen can be a cheap set of programmable buttons.
Could be nice for a user and maybe  a cost reduction for the 
manufacturer. Nothing special and I'm not impressed at all. The 
touchscreen has several drawbacks as have been already stated. To add 
one: screen buttons can take up too much space on the screen if the 
screen is not big enough. My screen must display useful information 
(that is what screens are for), and must have a fair size.

A touch screen is nice if you want to manipulate things.
Manipulating things: zooming in and out, rotating, moving, etc. As long 
as it is easier with than with a mouse, the touch screen is super. 
(precise manipulation is easier with a mouse)

Ergonomically: high resolution (duh) and easy to access.
Screens in ham transceivers used to be vertical, like a computer screen, 
also vertical. The 'classical' touch screens are more or less 
horizontal, like tablets and smartphones. Some manufacturers have tried 
to make hamradio equipment with touch screens that are somewhere in 
between: IC-7100 panel, Acom-2000 panel, etc.
I think we have to learn from the windows-8 computers and ditto laptops 
how we tend to do things. In which cases do we touch the screen?

High resolution info on a high resolution screen
A good resolution screen is as good as the resolution of the info.

No Jim, you are wrong here. CW is a carrier modulated by a digital
(on/off keyed) signal of a given (baud) rate.  That keying will
generate sidebands +/- the baud rate *just like FSK* or even AM which
can be observed on a spectrum analyzer.  The ITU formula is quite
accurate in terms of the actual bandwidth for signals with *properly* 
*shaped keying*.

Again, the excess bandwidth from improperly shaped keying signals
(clicks) and/or amplifier distortion is something else.

Hi Igor,

I think that some have operated at low temperatures in some winter
competitions -- the US North East gets pretty darn cold -- similar to what
you are talking about. I looked and easily found similar questions to
yours, but no answers!

The two things I'd be concerned about are the batteries and any
electrolytic components that may be damaged by extreme low temperatures.
The LCD screen will also stop working at low temperature, but I've never
broken one by freezing -- but perhaps I was just lucky!

I think batteries will have issues before most of the electronics. I'd
suggest building a small insulated (expanded foam?) enclosure to hold the
radio and battery. You could then stick some chemical hand warmers into the
container and keep everything at a reasonable temperature. Look at how the
"space balloon" people do things, they may have some tips. Alternatively
keep the batteries in an inside pocket of your clothing.

An email to the Elecraft guys may give some guidelines for temperatures
that may damage components... but apart from those, I'd just give it a try!

Good luck and let us know what you find out, so that we can answer  the
question next time it comes up. (I live in California at the moment and our
harsh winter temperatures barely touch freezing at night!)

Thanks Brendon,Bob and Kevin. I am not worried about batteries. My LiFePo4 
were tested at minus 20 C and the drop in capacity is insignificant. Looks 
like nobody tested K3 or KX3 at below freezing temperatures so I will have 
to be the first :) A bit scary...

IMHO CW can be seen as 100% AM modulation which will have 2 sidebands. 
Therefore the bandwidth will be dependant on speed or baud rate as well as 
shape of the wave form.

One could discourse all day on what "proper" is in this context without
ever a precise consensus among educated gentlemen. At some point of "ugly"
we would all agree that anything that sounds like that is improper.

When the only stateful levels were strictly on and off, and the rise and
fall transition time amplitude curves were set by a resistor and a
capacitor, one could make some simplifications in the discussion.

Today, often, as in the K3, the rise and fall times and shapes of CW are
DATA which goes DIRECTLY to RF via a DAC. For these the nature of the rise
and fall curve is not governed by a charge/discharge time of analog
components, but rather by whatever function generated the waveshape data,
which is stored, *read* as needed and never generated real time. In many
cases it is far more accurate to say that the rise and fall of a baud is
INTRODUCED, rather than the signal is keyed.

If the rise and fall data curves used for "keying" vary their "sharpness"
according to speed, then the description bandwidth increases by speed
certainly does apply. But if not, the bandwidth is governed by the pulse
generated by the rise and fall data, which could be the exact same from 1
wpm to 40 wpm.

We are so easily diverted into our lifelong, unconscious, and utterly
habitual analog thinking (note that I certainly do not give myself a free
pass here).

I was just looking at the P3 display of some traditional BC band stations
around here. A 30 over 9 station at 1490 kHz fills up 1480 to 1500. Using
the K3's AM-S mode on USB side the S9 station at 1500 kHz is clearly
intelligible, but the standard demodulation for 1500 is obliterated by the
1490 station. That ain't your granddaddy's AM out there any more. That's
some really complicated stuff that completely fills up +/- 10 kHz and
clearly not done the same from station to station. I'm going to save
googling that for a free evening when I don't have something broken to fix.

There is so much stuff I was taught by my WCTT Chief Engineer Elmer that I
am having to set aside.

No, many of SOTA activators have used a KX3 below freezing.  We just
haven't used one at -30C (-22F) like you originally mentioned.

Hi Igor,

I live in Minnesota and our temps get down similar to yours.  I have not 
tried my
K3 in those temps, but  I have had mobile rigs in early days of solid 
state and when
first turned on, nothing would happen for a few minutes until they 
warmed up.
Newer circuit designs may have changed that.

I would worry about the condensation that forms when the radio is 
brought into the warmth again.

73, Dick, n0ce

Subject: [Elecraft] Battery requirements for NPOTA activation with
 KX3/KXPA100

Having recently done several NPOTA activations I'll share my experience. 
I have a non-Elecraft radio permanently mounted in my truck (my nice K3 
station stays home), run about 100 watts into a typical screwdriver 
antenna. I ran off the single battery in my truck, which is good for 
about 50 to 60 amp hours (non-AGM battery).

In past years I've done contests where I hunt and pounce and have gone 4 
or more hours without killing the battery. NPOTA is way different! The 
last time I went out, not thinking about the duty cycle difference, I 
operated about 2 to 2.5 hours and when I went to start the truck the 
battery was dead. In that time I'd made 176 QSOs, so don't think that 60 
QSOs per hour is optimistic...it's easily accomplished if conditions are 
good. And that means you'll be transmitting a lot.

So, I killed a car battery in 2 or so hours. If you want to operate 6 
hours you're going to need roughly the equivalent of 3 standard car 
batteries. Not very scientific I know, but a reasonable estimate I think.

I'm now looking to install a second battery in the truck, as I want to 
do more NPOTA activations...

I have operated my K1 (after cap modification by Elecraft) & KX1 at - 
40 C & F with only my fingers suffering from the cold.  When I did temp compensation on my KX3 I took it down to -10 C.  I know KL7EDK in Fairbanks AK may operate on the Yukon Quest with a KX3 which gets very very cold.

Thank you Dick. Condensation inside the rig is a known problem. I will sure 
take care not to switch it on before it is dried out inside.

The coldest I've operated is probably about 20F (-7C).  I've never seen any
cold related issues with the KX3.

Thanks Jerry. +8F (-13 C) is the lowest mentioned here so far for KX3. I 
will have to wait till next winter to try temperatures lower then that. Now 
it only gets down to minus 8C in the night and day temperatures are all 
above freezing.

I?ve run my KX3 at +8F with no problems but that was SSB. I?ve not done any 
temp compensation on it. Also,
the radio was ?warm? +60F when started but was outside in the cold at +8F 
for about 5 hours.  It may have generated enough heat internally to help and 
I?m not sure if a cold soaked radio would operate the same from a cold 
start.  Great little radio!!

When I did the temp compensation the radio had cold soaked over night. The only problem that I remember was a slow display. I ran the radio up to 110F, 43C (radio out in the sun).

That credit was only for the code requirements (which I took advantage
of) not for the written elements which were different from the ham exam
elements contents.  The Telegraph exam contents remained the same as
they were in the 60s (or earlier) up until last year, the only change

became privatized.

No comment.  I was a FCC code examiner for three decades and lazy didn't
apply.

Code groups were never part of ham exams at any speed.

Hi Igor,
Although I haven't experienced your low temperatures I did get condensation
in the VFO encoder. The rig worked but only tuned for part of the turn of
the knob. It took about an hour to clear up once I started to warm it up.

Of course...I should have written more clearly if my post implied otherwise.

I took the written elements once, the only radiotelegraph candidate at the Kansas City FCC office.  The 100-question exam was 10 percent short answer and schematic draws.  After the examiner graded all the multiple-choice questions and I passed from just those, he asked if I minded if he did mot grade the remaining 10 non-M/C questions...i.e. zero credit.  I said OK.

I wrote:

I have no doubt...I was not casting aspersions on the examining staff.  They were not the ones who made the decision in the early 1990s to accept a ham 20-wpm read-only test requiring (after 1980) answering 10 multiple-choice questions about plain-language text, in place of the far more rigorous commercial Morse tests.

Exactly!  Yet some report, even here in the past few days, that their ham Morse exams were random character code groups.  Thanks for information to the contrary that can be neither doubted nor disputed!

Oops, my apologies: one of those was me, my excuse will have to be that it
was in 1973 and I guess those memories are no longer what they used to be!

I probably mixed that up with my code practice tapes, which definitely did
have 4 letter code group parts....

Message-ID: <56FC4198.2020002@coho.net>

I have successfully removed the KPA3 module and find one pin missing.  
On P68A pin # 6 is broken or cut flush with the header. The 
corresponding socket opening seems to be filled with a plug. Since I am 
not seeing any broken pin in the socket I think this is the way it was 
designed.  But as long as I have it open and the problem is power out I 
may as well ask what is most probably a silly question.

Any takers?

The space inside a KX3 is very limited, but you might consider some
dessicant to absorb the moisture when carrying the rig outdoors. It's silica
crystals and readily available from many stores including Walmart and gun
dealers (those folks like to keep their weapons dry and rust free when
transporting them). 

You can make up small non-conductive (cloth) bags that fit in the nooks and
crannies of the KX3. Of course, there's a lot more room in the K3. 

They last indefinitely. From time to time you can de-humidify them by
warming them for a while to drive the moisture out. 

We used to deal with them a lot on shipboard equipment, particularly
lifeboat radios. The dessicant changed color as it absorbed moisture and
we'd dry them out by putting them on top of a steam heat radiator or other
warm spot for a couple of hours.

Hi Igor,
Although I haven't experienced your low temperatures I did get condensation
in the VFO encoder. The rig worked but only tuned for part of the turn of

Silica gel crystals will also work well when placed in a case

Just for my own edification, were code groups ever part of the 
commercial exams?

It's been nearly a lifetime, but I sat for the 2nd Telegraph in 1956 [I 
was almost 16], and I vaguely think I remember two parts to the code 
element -- plain text and groups.  I also very vaguely think I remember 
the speeds were different [20 and 25?  or maybe the other way around? 
or maybe not].

It was an accident.  I intended to sit for the Extra since I had just 
passed the 2 yr service requirement and got to the FCC in the morning 
just before the telegraph exams.  The Extra was in the afternoon.  He 
told me to fill out the app and if I passed I'd get credit for the 
telegraph element on the Extra.

I was closest to that intimidating Boehme tape reader with the "steam 
gauge" speed dial, and ... not making this up ... the examiner had 
garters on the sleeves of his shirt and a green eyeshade.  I passed, he 
gave me the written exam ["What's to lose?" he said] which I passed 
exactly.  Lots of M-G set questions which I didn't know, but using 
maritime circuits for code practice paid off in operating knowledge I guess.

I'd appreciate actually knowing if groups were part of the exam since I 
can't trust my memory.

Look in Device Manager and you should see an added soundcard if all in

If it does not appear, or it appears with an exclamation mark, you might

People seem to be confusing US Ham and Commercial license exams. 

Fred is right, the COMMERICAL RadioTelegraph license back then had code groups was well as plain text according to my memory and ex-FCC man Phil's (K2ASP) comments. 

I believe Phil said the code groups were 16 wpm while the plain text was 20 wpm for the 2nd Class license. 

All I remember 59 years later was sweating perfect copy of the code groups! I had to retake the 2nd Class COMMERCIAL license exam in the early 1990's after letting my original expire but cannot remember if it had both or just plain text. After "pounding brass" for 60 years I was a bit more sanguine about the test by that time. 

My Novice 5 wpm and General 13 wpm tests in 1952 were plain text as was my Extra test at 20 wpm in about 1972. But those are AMATEUR license tests, not commercial. Those tests required solid copy of at least on minute on paper as well as sending to the examiner's satisfaction on the straight key at the FCC office. 

I believe near the end of the Amateur CW requirement all the applicant had to do was receive the CW message and answer some multiple choice questions indicating they generally understood what was sent. By then the exams were administered by VECs and many of them were not proficient in CW anyway.

I remember the FCC engineer administering the test consisting of plain 
text code for my Extra class CW test,
and some of the words were not spelled normally to see if we really 
copied each letter.

I do not remember a code test for the commercial license, but maybe 
credit was given for an Amateur License.
I kinda doubt that.  We were allowed 5 hours if radar endorsement was 
included.  The cost was around $45 ?? pass or fail.

Yes, and a little-known secret that can be revealed now was that some of

Wayne,

When you operate mobile, do you use some sort of magnetic mount to support the whip? Also does the metal of the vehicle take the place of a counter poise?

The KX3's BNC connector is rigidly attached to the right side panel, with a D-shaped bushing so it can't rotate, and a flexible wire from the BNC's hot lead to the PCB. So you won't hurt anything by doing this. Any 48" long telescoping whip with a base loading coil and BNC will work, though as I mentioned, I'm partial to the MFJ 18xxT series.

It has two female BNCs: one at the top for the whip, the other at the bottom at a right angle so it can attach directly to the radio. The radio connection can use either a double-male BNC adapter or a length of coax. The height is adjustable to match the height of the BNC on the radio.

I'm not Wayne, but I've studied this issue. Yes, the vehicle chassis 
needs to serve as the counterpoise for a mobile antenna, but I have yet 
to see a mag mount that does that effectively. VHF/UHF mag mounts are 
designed to do that by means of capacitance between the mount and the 
roof, but nearly all that I have seen have no contact between the coax 
shield and the enclosure of the mount!

At HF, I see no practical way for any mag mount I've seen to have 
anywhere near enough capacitance to a roof to work as a counterpoise at HF.

If you want to work mobile, you need to make a solid connection to the 
frame, AND it needs to be a part of the frame that is not insulated from 
the rest of the frame by PAINT. That isn't easy in most modern vehicles.

Two examples. With a Volvo S80 I owned about 15 years ago, I used a 
license plate mount for Hamsticks. The license plate holder was 
insulated from the trunk roof, and the trunk roof was insulated from the 
rest of the body by the hinges, so I had to bond around both. That 
worked pretty well, but I suspect there were still pieces of the body 
that were insulated by paint.

Second example. My current vehicle, a 2006 Toyuota Sequoia (big SUV) 
that I bought in Nov to move to CA from IL. It was winter in Chicago, so 
K9IKZ let me bring it into the loading dock of his biz, and we poked 
around to try to find good contact with the body. Lots of paint in the 
way -- I found bolts a few inches from each other with no continuity 
between them. I eventually mounted the antenna socket to the roof rack, 
and found a nearby bolt that did get to the body.

That worked pretty well as an antenna, but the vehicle has really bad 
susceptibility to HF RF -- at 100W on 20M, the main computer that runs 
the vehicle goes into "limp home mode." I've never bothered to try to 
fix it -- I was in the process of moving when I learned that (on an 
isolated stretch of I-80 in the NV desert), so didn't have time to chase 
it down, and because it was RF on the body that was exciting vehicle 
wiring, I figured that it would have been pretty difficult to fix. :) 
And my only interest in HF mobile is for long trips without the XYL, 
which I no longer take after I finished moving. I've heard that other 
big SUVs are far better in this regard.

If you use a mag-mount for an HF whip, be sure to use one with three magnets, not one. I tried a Hustler 17-m whip with a one-magnet mount, and it tipped over at freeway speeds. 

I agree that the capacitance of a mag-mount is insufficient. The coax braid may actually be serving as the better part of the counterpoise.

I gave up on the mag-mount and now have a bracket on the spare tire mount. Works great. 

On our KX3 web page you'll find a link to an application note about mobile installations. There are many subtleties.

While I found a DC ground on the bed of my GMC, I had a beautiful match...? Hint loss..? Put a 2" wide copper strap to the frame after grinding down to metal and using Penetrox to seal the connection.? Had to change the match at the base, but performance was noticeably better.? Less, loss.. I then went around an bonded ever piece of the body to the frame.? I am happy now.

I have a Little Tarheel screwdriver antenna on the 4Runner. It 
works well on 21MHz and higher, and less well as you go down in 
frequency. When parked, I try to add an external counterpose 
clipped to the ground side of the antenna mount, which seems to 
help on 40M. I really think you want your counterpose to be on 
the order of 1/4 wave long, and the 4Runner isn't 10 meters long.

I do remember doing search and pounce in the California QSO 
party on 80M. As I tuned up the band and found a new station, I 
had to re-turn the antenna, which I did while giving my call. 
Everyone who answered said something along the line of, "You're 
down in the noise, but we'll make it work." I thank them.
