Subject: [Elecraft] KX2 modification
Message-ID: <907de5c5-6f15-7ff4-d879-875b4f8570f1@mebtel.net>

Hi all,

We have had several inquiries as to whether our Pro Audio Engineering 
Kx22 Heatsink for the KX2 is compatible with the Harmonic Reduction Mod 
kit, Elecraft p/n KX2MDKTHS.? The good news is since discussing the 
issue with Elecraft two years ago we have been supplying the Kx22 
Heatsink with the Harmonic Reduction Mod already installed.? With the 
proper application of the thermal transfer compound we include this 
approach results in thermal performance better than either stock 
configuration.

In a similar vein, not long ago, I received a piece of furniture I ordered
from Italy.  I owed something like $30 in US Customs, but it arrived broken. 
The insurance claim, processed by the vendor paid for the replacement which
was then shipped.  The invoice on the second one was marked "replacement for
damaged product," and valued at $10, so it passed right through without any
duty or tax.  That's how Elecraft should describe and value the radio on
return.

On a side note, DHL USA is a horrible shipping company to deal with.  If you
have a choice when ordering something from overseas, avoid them.

Actually the best thing, as described earlier is to register the product
with customs before sending it for repair, including the form with the
unit, and having the repair shop return the unit with the form. No duty
should be owed. In the US, it is explained here. Most other countries are
similar. Basically you prove ahead of time the unit was in your country and
only temporarily exported for repair.

https://help.cbp.gov/app/answers/detail/a_id/133/kw/Sending%20Goods%20Back%20for%20Repair/session/L3RpbWUvMTU0OTAzMjY5NC9zaWQvUGdELXRpNm8%3D

Various country's customs frown upon companies playing fast and loose with
valuations.

I agree with your poor opinion of DHL. I have had a much easier time with
USPS.

Both Bob K4TAX and Bill NR4C figured out the problem...

I've been using my K3s for a few years on all bands except 60 meters. So my
original setup was from a long time ago.  At that time I set all my active
bands to DATA MD DATA A.  When I tried 60 meters for the first time
yesterday to help someone who needed RI for their WAS, I didn't think to
check DATA MD on the 60 meter band.  I suspect it defaults to AFSK, which
is a LSB mode.

So moral of the story -- if you have to be in REV DATA you probably haven't
set the DATA MD to DATA A

Subject: [Elecraft] Tx distortion
Message-ID: <1549037610369-0.post@n2.nabble.com>

Hi!

I have hade my k2 about 14 years with number 4503 and it been a pleasure to
build and operate it 
but now I got problems with distorsion on the TX audio. 

It will usully work  fine when it been resting over the night but after a
while the distorsion slowly comes.
I t start with the base in the audio are reduced and then the treble are
cracking up. It sounds like you driving a audioamplifier just  alittle to
hard. 
The problem is the same with thek2/100 or when it removed from the k2.

I have used a 2 tone signalgenerator and loked with a scope att the signal
after the ne602 and after the 10w amplifier 
and it looks fine to me but the bandwith of the scope is just 15Mhz so I
might be missing something. 

I have replaced u5, Q1, D2and some capacitors on the ksb2 board, tried to
find any bad soldering but no luck.
Can it be a bad capicotor in the  ssb filter or in the Tx signal path?

Grateful for any advise.

I do have everything labeled so I do get everything into the right connector.  The problem I have had to arise several times, once everything is ready to check the, the RS232 serial port will not communicate.

From where I thought I had it fully plugged in to actually being full could not have been a 64th of an inch if that. Not even sure if there is any further travel I just hear the faint click.  So if you use the RJ45, even though the RJ45 appears to be in fully, if you have com port communication problems to your computer or cant talk to your P3, see if you hear that faint ?last click? in the RJ45.  It is not just my particular K3S, I have seen the same situation on a second one.  73 Mike K4PI

I forgott to mention that there is no distortion on Rx only on Tx does that
mean
that the ssb crystel filter is ok or can the filter still cause distortion
only on Tx

Grateful for any help

If the filter is OK in receive, it will also be good in transmit.  The 
only things which differ are diodes D4 and D14 on the KSB2 board.

I would look for one of 2 things - RF Feedback and a bad microphone.

To check for RF Feedback, operate the K2 into a dummy load and listen 
with a monitor receiver using a wire for an antenna placed near enough 
to the dummy load to obtain an S-9 signal in CW.

To check for a bad microphone, the best way is to substitute another mic 
of the same kind.

A question - did you change from an Elecraft microphone to something 
else?  If that 'new' mic is a dynamic type, did you remove the bias 
resistor?  If the bias resistor is left in and a dynamic mic is used, 
the bias voltage will drive the mic diaphram off center causing it to 
"sound funny".

  Many thanks for the answer and good to know that I can rule out the filter
as the problem.

  I have not change anything in my setup that I used for severel years and
that is main reasen
  I believe something has happend to the k2.

  All the tests I done so far has bean made in to a dummyload and a icom 735
as receiver.

  I use a shure sm58 microphone that is connected to symetrix 528e micpreamp
, voiceprocessor that
  drives the k2. I also have a Icom microphone that I connect directly to
the K2 and it do not make
  any difference on the distorsion. Both this setups have worked nice for
many years.

  If I use the icom 735 as transmitter and k2 as receiver it still works
fine both with the icom  microphone or the symetrix unit and shure
microphone.
  
  The strange thing is when the k2 has been turned of for a couple of hours
and then
  start to transmit the tx audio is mutch better then it comes like you
slowly turn upp a pot
  the audio gets thinner and the distortion increases.

 I monitor the driving signal from the symetrix unit at the same time to
rule out that as a cause. 
 Looked for cold soldering on the ssb bord.

 I have also looked for any components to get varm and so far it is just Q6
on the RF board that gets
 araond 122 degrees Fahrenheit that do not seems like a problem.


 I have meassured D1 and D14 and looks ok. Can Q2 on the ksb2 board cause
this problem?

what that means?

The amplifier
also has a remote (REM) jack that can
be tied into your remote power control
system to power the amplifier on with
12 V dc applied and off if removed.

Hi Jorge

You can use a network controlled relay to apply 12 volts to a pin on the connector allowing it to be turned on remotely. 

If you have the amp configured to follow radio frequency it makes for easy remote operation with radios capable of remote.

Message-ID: <429bd649-3544-e12c-4de9-7b2892fa9e84@blomand.net>

I've seen consistently that the 6M TUNE power on my K3S, s/n 10163

performs correctly on all bands except 6M.?? I've completed the TX Power

Per Band set such that the KPA500 is driven correctly from the K3S.? The 
TUN PWR value as set in the CONFIG menu is 020 for 6M.?? But when TUNE 
is pressed the VFO B display is 16 watts and the measured output is 16 
watts.?? On other bands, when TUNE is pressed the VFO B display is 20 
watts and the measured power is 20 watts +/- 1 watt.??? Also when the 
PWR is set to 100 watts, the 6M? measured output power is 100 watts +/- 
10%??? This is measured using? a known good 50 ohm dummy load and two 
different power meters to confirm the results.

MCU is 5.66,? FPF 1.26,? DSP1 is 2.88.??? I think these are current.

Not a big deal in any way but just curious as to why?

Any ideas?

Mike,

With RF and microphone out of the way, I would look to either coupling 
capacitors in the AF path (C20, C32, and C34) or the Speech Compressor 
IC for the problem.

Unfortunately, the '2165 speech processor IC is no longer available - 
the KSB2 was redesigned to use the '2166 IC instead, but it is not a 
drop-in replacement, and if that turns out to be the problem, it means 
buying a new KSB2 board.

Don W3FPR

Both of my K3S's do exactly the same thing here. Both are running F/W 
5.66. I reverted one to a previous F/W (version 5.64) and the same 
symptoms persisted. I did not measure the actual output with an external 
Wattmeter; these are the values as reported by the K3 itself.

It's not a big deal for me but it certainly seems curious.

Don,

Thanks for the suggestions.
I am thinking of putting the outputsignal from the symetrix 528e microphone
amplifier
 to c20 on the ksb2 board so I will bypass U3 and let the signal go direct
to u5 NE602 
and that way found out if u2 is bad.
I will come back with the result.

The Symetrix unit could be involved. Why are you using it? What mic are 
you using?

Mike,

Notice that U2 also has an output that is involved in PTT and VOX 
detection via U4 and the COMP OUT signal.
The signal at the output side of C31 is driving an impedance of about 8k 
ohms.  I don't know what your Symetrix mic amplifier is capable of driving.

The symetrix is a pro audio processor. 200 ohms source impedance and is easily capable of over driving any transceiver.

Thanks for answers.
The symetrix output impedance is 200 ohm and it is recommended to not load
it
lower then 600 ohms.
I lifted the plus side of c20 and  connected a 10k resistor to ground.
I connected the signal from the symetrix output to the plus side of c20.
This way the signal comes direct to ne602 and u3 is not involved.

The distortion is still the same and no difference what signallevel
I put out from the symetrix. from a very low level until a 3 bars of 
alc reading. I am still listening to the Lf signal from the symetrix just to
be shure
it is no clipping from the unit.

I know this is not the way to drive the k2 just trying to find a way to see
if U3 is the problem.

The microphone I drive the symetrix is a shure sm58 and I also
use a icom hm12 that i put direct in to the K2.
The first 6 years I  used the Icom microphone then  the last 8
years I used the symetrix and Shure sm58 that improved the audio.

Thanks guys for the verification on your radios.

I've tried it with TUNE power at different values, 5W, 10W, 20W, & 
30W.?? In all cases, the value for other bands is as selected, except 
for 6M where it is always 70% of the selected TUNE power.?? With this, I 
figure it is a firmware issue.

Still ....... no big deal.?? Just curious.

Mike,

It may not be the KSB2 board after all.  It could be a problem with the 
base K2 PA stage.

With the KPA100 fully removed, what is the maximum power output?  Also, 
what is the DC voltage during transmit as measured by the K2 meter (tap 
DISPLAY to see the voltage), then transmit.
A higher voltage will keep the IMD low.  Use no lower than 12 volts for 
best results, 13.8 is preferred.

Do a TUNE and measure the DC voltage on the base of either Q7 or Q8.  If 
it is outside the range of 0.60 to 0.64 volts, there is a problem.  Also 
note that there is a /CLASS AB signal that also affects bias for SSB. 
Go to transmit (not TUNE) in SSB and make certain pin 6 of RF Board U1 
goes to zero.

73,
Don W3FPR

Chris,

Do you have a saved configuration file from when it worked right?
If so, you can do a "Parameter Initialization" as described on page 66 
of the manual, then Restore the configuration

Even without a saved configuration, you can try doing a "Save 
Configuration" now so you can restore it after the initialization.

If neither is workable, then write down the menu settings so you can 
restore them manually.

Should all that fail, Elecraft may have to original factory 
configuration file.  Ask by emailing support at elecraft.com with the 
serial number and original owner's name and callsign.

Don W3FPR

I think something like this can happen if you don't do all the firmware 
loads (DSP, CPU, etc.) at the same time so that they are all the same 
compatible firmware versions.

It's been at least 15 years since I looked at a K2 schematic, but Don is 
very well equipped to help you there. The photo on the data sheet for 
the 528e shows that none of the TRS jacks appear to be properly bonded 
to the shielding enclosure, as specified by AES48. This is a classic Pin 
One Problem, and a path into the 528e for RF if a cable is connected to 
one of them. It isn't clear whether the XLR is properly bonded. If it 
isn't, that's another possible path for RF. That could easily be the 
cause of audio distortion -- what we commonly call "RF feedback."

This unit is designed to operate at an output level in the range of 2V 
RMS, which as W2XJ observed can easily overdrive the K2. The best way to 
drive the audio chain of a rig like the K2 is by the addition of simple 
voltage divider. I'd start with 26 dB, which is a 20:1 ratio. I'd go 
with 1K for the series resistor and 47 ohms for the load. You will, of 
course, need a cap in series with your drive to the K2 so that you don't 
upset the bias.

The K2 SSB board is low on gain. When I was using one, I worked out a 
simple mod to increase the gain by about 6 dB and also roll off the low 
end a bit. This allows the mic to hit the peak limiter a bit harder. At 
the time, I was using an EV RE11, also a pro mic, but without the 
proximity effect bass boost of an SM58. I gave notes on that mod to Don 
many years ago. No new parts are needed -- I simply moved two or three 
resistors and caps around.

I recall that there were other mods done in the audio chain to increase 
gain.

I believe the specs indicate that output power on six-meters is less than other bands. Maybe ten is also down, not sure.

Just the other day ... just west of Panama City Beach in the Florida
Panhandle, AX-1 set up using the camera tripod adapter on a short tripod on
a 3rd floor balcony, K2 running about 12 watts and using the KAT100 tuner
... worked KH7XS on 17 meters.  

I'd say the antenna works fine!

(Warning: the following is not Elecraft specific!)

It's not a dumb question at all. Years ago, I used an IC-706 on 6M with a small rotatable beam antenna on the roof. I had rearranged the shack, making everything a bit neater. It was all good, until one of the locals came on and told me that he had been monitoring, and my signal had gone from great to garbled. Turns out I had neatly run the new 10' power cord for the rig down the baseboard from the power supply on my workbench, to the desk where the rig was located, about 10' away. The signal coupled into the power cord when the antenna was rotated to a certain direction, so the RF was coupling into the rig and/or PS. That really messed up the transmitted signal. 

So, look for some "dumb" change to your overall set-up as well.

Good luck! 73,

10' is almost exactly a half-wave on 6 meters.  Your power cord was a
"worst case" for RF feedback on six.

Yeah, that's why I mentioned the length. It was an early "teaching moment" in my ham radio career. Surprisingly, it only took me a few minutes to figure out what I had done, but I had to move the power supply and workbench, and coil up the 706's power cord. I didn't like the new, new shack layout as much as the old new one, though. It also proved to me that some chaos is OK - being too neat has always bitten me somehow!

Don't forget about the length of the ground conductor as well. I've seen 
and found more than one instance where the ground conductor was a 1/4 
wavelength on the band which caused RFI in the station.?? That puts the 
station at 1/4 wave or a maximum voltage point above ground.? It was 
acting like a receiving antenna in the presence of the transmitted 
RF.??? For that reason, I do not use an external ground on my station 
equipment.? It is not needed.

Jim!
Thanks for the information I appreciate it. And thanks Ralph there is no
stupid question
I am grateful for all help I can get cause there can be something I have
missed.

Jim I use a resistordivider to get the right level to the k2 and also
ferritcords on all cabels that
enter the symetrix.
I have the same level of the distortion if I run 500w with amp to an antenna
or only
1w to a dummyload so I hope I am right to rule out rf feedback as the cause.
Also that I have used the same setup for many years without any problems
make me
think that something has happend to the k2 but I can be wrong. 

The strange thing that is confusing me is when the k2 been turned of over
the night
there is almost no distorsion when I start to transmitt .
then it slowly arrives in the first couple of minutes.

Don,

I have done some measuring on the powerstage.
dc voltage during tuning is 14,1 v
Bias Q7 is 0,652v when tuning.
U1 pin6 43mV on ssb transmitting.
I get about 10w max output (do not have a bird)

all measuring was done with a fluke 179.

Q6 gets mutch varmer then Q7,Q8 is this normal?

The strange thing that is confusing me is when the k2 has been turned of
over the night
there is almost no distorsion when I start to transmitt .
then it slowly arrives in the first couple of minutes.

There are so many things wrong in this short paragraph that I hardly 
know where to start. I strongly suggest that you buy and study N0AX's 
recent ARRL book on Grounding and Bonding. What you seem to be 
describing is also a violation of the National Electric Code. And while 
you're at it, buy and study the ARRL Antenna Book.

Mike,

That sounds like some old component failing as it warms up. Have you checked all electrolytic capacitors in the circuit(s)? I have a couple of radios from the '90s that I've had to re-cap, and my 1993 Ford truck has three electrolytics in its main engine control computer that were bad. I'm sure that there are other active components that could fail, but lately, my experience has been that electronics from the '90s and early 2000s seem to have bad capacitors fairly often.

Mike,

Is there any chance you have the K60XV option in that K2?
If so, you can set split the transmit path into 2 pieces because the 
Transverter output takes its output from just after the bandpass filters 
- i.e. - it does not use the Q5, Q6, Q7 and Q8 stages.

Set up for a transverter band operation with the output in the range of 
1 mV - It should not matter which is the IF band.

Monitor the output at the Transverter output to check for distortion.
If present, the problem is in the RF Chain before it reaches the 
amplifier stages.
If it is clean there, look at the RF Chain after the bandpass filters.

73,
Don W3FPR

Subject: [Elecraft] KX3/PX3 for sale
Message-ID: <cb5da8b1-db36-804c-d8fe-2ef2b70f6dcb@gmail.com>

Hello All,

I have a KX3 and PX3 set for sale. There are lots of options included. A 
few options are nifty stands, side rails, from covers, heat sink, cw 
paddle, signal link USB, Side Kar, and a custom aluminum base that holds 
all of it. Unit has been back to Elecraft for calibration and alignment.

I can send a complete list and photographs.

Paid 3400.00 and will sell for 2400.00. Do not want to split up.

I'm looking to purchase a KPA500 and KAT500. If someone has one will 
consider trade.

Bill,

There is not any requirement to register it with Elecraft.

However, if you need to send the K3 for service, you will want to make 
sure that serial number is updated with your contact information.

Mike,

Of some concern is the heating of Q6 - but I don't think it is 
unreasonable if you can still hold your finger on it.

Hint for troubleshooting.  *IF* the problem is in the RF amplification 
chain (Q5 thru Q8) then it should appear in TUNE as well as in SSB.
I would suggest that you measure the DC voltages for Q5 thru Q8 after 
the K2 has been idle for some time, and then after some period of 
operation after which the distortion could be expected to begin.

One thing you might want to try is to measure the resistance from the Q6 
emitter to ground before distortion begins and after it starts.  It 
should be 1.5 ohms (so use a low resistance scale).  If it changes, 
consider replacing R50, but also be aware that there may be something 
causing the voltage on the base of Q6 to change as well.

If your Q6 is a 2sc5739 instead of a 2SC2166 (the 2SC5739 has a plastic 
tab instead of the metal tab on the 2SC2166), then change RF Board R46 
to 330 ohms.

Bill,

When you need to send it in for repair, email support at elecraft.com 
asking that an RSA be issued.
Explain that you bought it used.
You should also include your K3 serial number and your contact 
information in that same email.

The twenty meter net went rather well.? Once I had a chance to call the 
net I was met by a solid tone which is always a good sign.? The 
tail-enders get a break.? By being a second after the solid tone I can 
get letters from your callsigns.? Signal reports all had some QSB but 
ranged from S1 to S7.? The deep freeze of last week only remains in 
Fargo, North Dakota the rest of you were much warmer.? I also got a link 
to an American tea grower.? That should be fun to follow.

Good Evening,

 ??? Compared to last week Fargo, North Dakota is undergoing a heat 
wave.? It's up to 0 degrees Fahrenheit :)? Iowa has dense fog and 
sauna-like temperatures in the mid 40s.? My brother in SW Wisconsin 
reported a flood just west of his barn.? His?Mangalitsa and mulefoot 
pigs are fine as are the Belgians.? The chickens are staying inside 
laying eggs.? Around here the snow has started again.

 ?? Both bands had slow QSB but forty meters had some fast flutter too.? 
Propagation keeps improving week by week.? Oh what the sun can do when 
it's not set all the time.? The steady hissing noise was less too.? 
Reading on spaceweather.com I find we're leaving the latest stream of 
solar wind.

Subject: [Elecraft] K2: I killed my KPA100
Message-ID: <71246239.8676.1549250037109@wamui-marley.atl.sa.earthlink.net>

I tried to tune the KPA/KAT100, and the SWR went to red. I quickly exited 'tune', checked all of the connections, and the antenna, and tried again. Same result, except before I could take it out of tune (it was tuning maybe 2-3 seconds), all of the KPA/KAT100 lights went out. The K2 was fine. I took the amp off of the EC2 and installed it directly on the K2. When I powered on the the K2, using its low-current supply, the K2 came up normal, and didn't recognize the amp. The base K2 seems OK, and transmitted into my dummy load, and could hear the NGEN. When I powered it through the KPA's high-current supply, the K2 was dead. The base K2 again came back to life when I removed the KAT's power, and went back to the base K2's supply.

I measured the 12V supply when plugged into the KAT100, and I get between 1V and 2V - the PS must be protecting itself - it looks like there's a short...

Earlier today, I had been trying to get my computer to talk to the K2 through a logging program. After I built the rig, I tested my cables and the KIO2 by successfully controlling the K2 with 'K2 Remote', so it was working. Today, the logging software would poll the K2, and get no response. 'K2 Remote" couldn't see the rig either. The DB9 connector that connects to the KIO2 has the cables to the KPA/KAT and serial cable, and I made sure the computer's connector was wired correctly for interfacing a "normal" serial cable to the KIO2. It all worked.

I looked at the KPA schematic, and thought a diode, or something in the current sensing circuit might have failed. I removed Q5, and it tests just like my new spare. I lifted one side of D10, and it seems to test OK, but when I did the same to D9, it looked weird - but I don't really understand that device; In "diode" mode, I get .150V in one direction, open in the other. When I test it in resistance, I eventually measure 80-90ohms in one direction (it takes a moment to settle), but it's open in the other. It might be OK? I hope I didn't kill U7. 

I performed the resistance tests in the KPA manual, and they are nominal. Q1 and Q2 test OK, and I think Q3 and Q4 are OK. Q3 tests differently than Q4, but looking at the schematic, I think what I see makes sense.

It also occurred to me that when I was trying to get the logging program to work, I might have caused a failure in my cables while I was hooking and unhooking the serial connection. That might have caused a communication problem that made the amp go a bit nuts.

Sorry for the long message. ANY suggestions will be greatly appreciated!

Jim,

My usual procedure when tackling a problem of that nature is to first 
isolate the problem to one component.
You have already apparently checked out the base K2.

Next, remove the top cover from the base K2 and connect the KPA100 to it 
(remove the KPA100 from the EC2 enclosure).
Put the KPA100 upside down on a box or book about 1/2 the height of the 
K2 and plug the cables into the K2.

Then test with an external wattmeter and a dummy load connected to the 
KPA100 SO-239 antenna jack.

First power the base K2 from the 2.1mm coaxial power jack.  Check at 5 
watts and at 10 watts - this checks the transmit path through the KPA100 
in QRP mode.  Use an external wattmeter and a dummy load.  Does the 
external wattmeter agree roughly with the K2 display indication and the 
power knob setting.

If you have a much higher actual power level on the external wattmeter, 
the KPA100 wattmeter diodes D16 and D17 are the first suspects - replace 
them.

If all is well so far, remove the 2.1mm power plug and power the 
assembly with the APP connector on the KPA100.  Make the same test.

After that, check the bias on the KPA100 for a 400ma rise in current 
with the K2 set to CW and in CW TEST mode.  Hold the mode button until 
TEST appears in the LCD, and the CW icon will blink.

Do a tune and check that the current rise from receive to TUNE is 400ma.

Then set the power to 50 watts and do a TUNE.  Read the actual power on 
the external wattmeter.  With a TUNE, it should be about 20 watts.

If it is greater, you have a problem with the KPA100 wattmeter - likely 
diodes D16 and D17 have been damaged and need to be replaced.

More troubleshooting is possible, but that is a good starting point.
If all goes well with those tests, then I can tell you how to check the 
KAT100 alone (without the KPA100).

73,
Don W3FPR

Sounds like a bad encoder and was just coincidental to the FW update.
On the 4 small push-button encoders, tap each one and you will probably 
find one that does not toggle the LEDs.
The old encoders leak resistance internally and it disrupts the 
push-button matrix causing wrong button pushes.
Replace all 4, Elecraft part number E640018.
You may be able to tap or snap the bad one repeatedly to get it back to 
working (but it will fail again).

I am the new owner of the Elecraft K3 and there is a lot to learn. The first question is how to check the SWR without the ATU so the antenna can be as close to resonance as possible (other than an external SWR meter)?

out of the RF path.? If you don't have SWR on the left of the bottom 
line of the S-Meter, hold DISP/METER to switch to it.? Press key, read SWR.

Subject: [Elecraft] [K3] Spontaneous HI CURR, audio reduction in RX mode
Message-ID: <1549334637962-0.post@n2.nabble.com>

Over the past several weeks, and especially during the NA Sprint CW contest
last Saturday night, I've noticed spontaneous brief flashing of the HI CURR
warning *in receive mode*, which is accompanied by an immediate reduction in
headphone audio (though not complete loss of audio).  It is as though the
receiver's RF attenuator was switched in after the HI CURR warning was
flashed.  

My K3/10 is up to date on all firmware and has a serial number in the 66XX
range if I recall properly.  I have yet to discern any correlation with
transmit mode behavior, which has never displayed a HI CURR warning.  My gut
instinct is that this may be one of those pin corrosion symptoms, especially
since I've had some strange responses to front panel button presses that are
not repeatable.  The receive audio seems to come back, but I can't tell why
or when in relation to anything I've done with the radio controls........

Has anyone else seen the HI CURR warning displayed only in receive mode with
accompanying loss of receive signal strength?  I've searched the archives
and found plenty of discussion about HI CURR warnings, but nothing quite
matches my K3's observed behavior in receive mode.

Mike, K8CN

Don,
Thanks for all help.
I have measured on q5,q6,q7 when it been resting over night and when it is
warm
and the difference is smal.

q5 base cold )7,9 varm 7,9
q6 base 1,04 emitter 0,28 varm base 1,03 emitter 031 caculeted gives Ic
200mA Pdissipation 2,8W

q7 cold bas 0,658    varm 0,647
All in ssb with no modulation.

I looked with he scope on the base of q5,q6,q7 on the3.8 MHz signal in
tuning
and on  q5 I have a nice sinuswave but on q6 it lookslike a sampled digital
sinuswave
a sinus stairway. On q7 base the positiv side hase roud sinuswave form but
the negativ
side is like a saw vawe sharp edge.
Maybe the scope loads the signal down I do not no the cap. of the probe but
guess it is
about 16pF.

The strange thing is way there is almost no distotion when it been resting
over the night
but comes in after a couple of minutes transmitting.
I put it out in the cold for a while but the distortion was still there even
if it was cold
so it do  not looks like it is the temp more like a old care battery that
almost empty but will
get back a little power resting a night even if you do not charge it.

I have replaced the electrolytic caps on
the ksb2 board but can there be bad caps on the controlboard
that effects transmitt but maybe receive just a little?

I been thinking if there is a problem with the bfo or vco it should effect
Rx as mutch as Tx.

Jim,
Thanks for the advice. It is also my experiece that electrolytic caps are
the main reasen for mailfunction
specially in a bit older electronic euqvipment. I have replaced all el.caps
in the ksb2 board but not any
on the other boards mostly because I beleive they are commen with receiving.
On the other hand can there be any circuit that draws more current in Tx
then Rx and start rippel on the
dc voltage ?

Don,

I forgott to mention that I do not have the k60xv option but that hade been
a nice way
to rule out the powerstage.

 I wonder   can there be any circuit that draws more current in Tx then Rx
and causing rippel on the
dc voltage during tx but not rx due to a cap that has lost capacitans?

Have replaced all el. caps. on the ksb2 board but not any on the other

Howdy Gang.

Recently picked up a nice PX3 to use with my KX3 and have been playing with the menu options but can?t seem to find the one I want.

I?d like to make the upper frequency portion of the display full screen?.I don?t need the bottom waterfall.

Is this possible?

Seems like largest screen I can get is about 1/2 size.

Am I missing a menu option?

Appreciate any info/assistance.

Thought I found the correct adjustment by going to MENU item ?Height of waterfall display?.

I got the full screen I wanted?but after I turned the KX3 on the large full screen changed to about half size.

Tried gain several times without success?I can?t seem to replicate the full screen I want.

Am thoroughly confused now so any help is really appreciated.

Mike,

There is very little change in current for the low level stages between 
receive and transmit, but the RF amplifier stages Q5 thru Q8 draw more 
current in transmit.

Have you checked your power supply to make sure it is not producing 
ripple or low voltage during transmit.  A low power supply voltage will 
increase the IMD significantly.
Check the power supply connections as well.  Monitor the voltage the K2 
sees during transmit by using the K2 display function rather than 
measuring the power supply voltage directly.

73,
Don W3FPR

I missed that the collector q6  must be the most ineresting pin to look at
and when tuning on 80 meters there is a nice 3.8 Mhz sinuswave.

Ok, try holding the menu/labels button at the lower right of the px3 to
change the bottom labels selection. It cycles through options, too. You
should get an option with no bottom labels and no text box.

I believe I found a potential answer in the K3 manual (to my embarrassment, I
should have looked there first, eh?) under the Troubleshooting section,
Receive mode:

"HI CUR or SPKRS=1 warning: HI CUR may indicate a shorted left speaker
channel; the K3 will
reduce AF gain."

Funny thing is that I don't use the internal speaker, just headphones
connected via the rear panel PHONES jack, and have never plugged anything
into the external speaker jack.......I guess I'll unbutton the case and see
if any wiring is awry.  The intermittency of the HI CUR warning in receive
mode is puzzling - if there's a shorted audio channel, I would think it
would stay shorted unless my headphones have an intermittent short on one
side.

Thanks, too, to Joe, 4Z7JBA, for his offline suggestion of another potential
cause for the observed behavior in receive mode.

Message-ID: <2b82f8f7-e41c-3144-ed6e-9e045084d6ce@denstarfarm.us>

So I have two programs running to decode FT8.

By using Left and right chan of the audio (tnx N5TM), the two iterations
of WSJTX can decode the K3 Rx USB Codec 2-Chan-48k audio individually.

Now I would like that WSJTX of the Right-Chan on the Sub-Rx to know the
frequency.

Personally, I am using DxLabSuite's "Commander" to control the K3 ...
and when running this way, I see that Commander "VFO-B" sees the correct
freq.

Anyway, I can't get that QRG out of Commander, but that's alright. I
sent a screenshot if they make it to the list. I also tried to guess a
way outside of "Commander' to make WSJTX read the Sub Band, but cvan't
do that either .

Thus, my question to y'all

Stephen,

What is needed is a KeyOut from the driving transceiver - that is an 
output which is grounded when the driving transceiver goes to transmit.
The KPA500 will frequency sense if it receives a short burst of RF, so 
the band data is not necessary, just connect the transverter and 
amplifier in the Basic Configuration.

You will have to consult with the SDR transceiver folks to see if there 
is a KeyOut connector (I did not see one when I looked a some of the 
ads).  Without that, the SunSDR2 cannot key any amplifier.

You might want to try the forums for the SDR  radios because their have been discussions on this very topic.  Hope this helps.

With thanks to Bj?rn SM7IUN and Mike VP8NO for pointing me to the firmware
revision notes, I checked my installed firmware and the K3 Utility and find
them to be fully up to date.  I'll go quiet on this issue until I've had a
chance to reload the firmware and open the case to explore the board
connectors.  I appreciate the guidance from those with better memories of
firmware revision notes!

I have a KX3 issue and I hope you folks can help me. I purchased my KX-3 used last year. It came with all the good stuff including 2 meters. I used it to check into the local 2 meter repeater several times last year but have not used it for any voice modes since. I am a CW guy.
Yesterday I tried to use it on 10M SSB and was getting no audio indication on the level meter. Tried it on AM and FM with same results. When I got home I tried the MH3 Mic on my KX2 and it worked perfectly.
I glanced through my "quick reference" ( it didn't come with the manual when I bought it" and didnt see anything obvious about turning the audio on or off.
Any ideas fellers?

Subject: [Elecraft] KPA1500 ATU
Message-ID: <8451d596-59a8-ff2c-a2df-2d2488915d91@sdellington.us>

Ever since I received my KPA1500 (SN 00178), I've observed that the ATU 
sometimes won't achieve a match better than about 1.4:1, even though the 
antenna SWR is well within range. (ATU STOP TUN SWR = 1.0:1, tune power 
40 W) Now, 1.4:1 doesn't sound that high, but the amplifier will often 
not operate at full output at that SWR, either due to excessive current 
or drive power. This is particularly troublesome when tuning across a 
band. Clearly, the KPA1500 is designed to deliver 1500 W to a 50 Ohm 
load, with little margin for a mismatch. More margin would have 
increased cost, size, and weight, of course.

Just to be sure there isn't something unique wrong with my KPA1500, have 
others observed similar behavior?

A little ice on the antenna this morning provided an opportunity for a 
test. On 40 meters, the antenna SWR was 2.2:1. The best match the 
KPA1500 ATU could attain automatically was 1.4:1, in multiple attempts. 
I was able to manually get it down to 1.1:1. (SWR as indicated by the 
KPA1500 display.) It was a little tricky, requiring one value to be 
increased beyond the SWR minimum before the other was adjusted, as often 
happens with manual tuners. With the KPA1500 ATU bypassed, the K3 ATU 
automatically got it down to 1:1 on the first try.

My conclusion is that there's something about the KPA1500 ATU algorithm 
that prevents it from achieving a better match, in some cases. (I'm 
assuming that, aside from their power ratings, the components in the 
KPA1500 ATU and the K3 ATU are similar.)? I'm wondering if the KPA1500 
ATU algorithm could be improved to perform more like that of the K3 ATU. 
That would allow operating the KPA1500 closer to full power across a 
band without having to ride the power control.

Further details of ATU component values, etc. are available.

Don,

Thanks for advice.
Have checked with to different powersupplies one is a icom ps15 with new
caps. and the other is a 
homemade unit both is linear with transformer.

The voltage looks stable on k2 display with 13,8 from Icom and 14,2 from the
other.

Looking with the scope  I see 120mv ripple with Icom and 80 mv with the
other
on voicepeaks and ssb tx.

I have replaced c16 and c13  on the controlboard with no inprovment.

Hi Ken,

At the frequency of interest, the KPA1500 ATU goes right to bypass mode 
with a dummy load.

Hi Mike;
Can you go to config menu item "FW REVS" an tell me what you see please?

If you are still getting the HI CUR warning, the U1 audio chip on the 
DSP board may have partly failed and will be getting HOT!
It can heat enough to MELT the DSP board and cause an internal short 
that destroys the whole board!
If you can catch it before that happens, you will save a lot of money 
and grief.
If you take the top cover off, and the upper left area of the front 
panel, directly behind the BAND up and down buttons, is the audio chip 
on the DSP board.
It is a black cube about 1/2 square at the top corner of that board. 
Stick a thermometer down there.

GM Neil,

I regularly use my KPA500 on a generator.  This week, I'm using it on a
Cummins 3.5 KW in our RV.  One year ago, I used it on a Harbor Freight
Predator equivalent to the Honda 2 KW inverter.  It works well on all three.

The only caveat is when operating CW, I needed to avoid using the "Econ"
mode which sets the idle speed much lower.  The Honda and HF versions didn't
like the sudden change in current draw and would fault.  As always, check
the HV supply reading on the KPA500 to determine if a different transformer
primary setting is necessary under load.

I want to add the KPA500 manual describes the different primary tap
settings.  There seems to be a lack of manual-checking going around these
days.  The updated manuals (firmware changes) are invaluable tools! 
Fortunately, Elecraft allows making notes in the PDF versions of their
manuals (copy and paste) which is much easier to accomplish than in the
printed versions.

73, Bill, K8TE

Same for our group working CQP and 7QP. A single 2000i works great to 
run a single K3/KPA500 station. We use Thinkpads for logging. W6GJB 
bought the device to sync two 2000i generators, and we use that setup to 
run two K3/KPA500 stations. We run 120V.

When we were still doing CQP [Alpine County] from Camp FYNO at 8,500 ft, 
we had a Honda 2000i.? Outside the contest, it idled all night powering 
the electric blankets. During the contest, it would not tolerate either 
CW or SSB in that mode.

Quite a few DXpeditions have run in the past few years with KPA500s and 
Honda generators. I think you'll be fine.

Message-ID: <86248510.12375.1549490358116@wamui-bison.atl.sa.earthlink.net>

Hi Don,

I got the following results:

1. Base K2 seems to be OK.

2. The KPA100 is upside down next to the K2, and everything is powered through the K2 and its power supply. Using the LP-100 and 50ohm dummy load, the 5W and 10W measurements through the KPA100 check out nominally.

3. When I apply power through the KPA100's power port, and using its power supply, the K2 and KPA100 are dead. The power supply measures about 1.8V when plugged into the KPA100, but ~13.5V with no load. 

4. As I mentioned below, I previously checked D9 and D10 and Q5. D10 and Q5 were OK, but I didn't really understand what I saw when I checked D9. From my first post:

"I lifted one side of D10, and it seems to test OK, but when I did the same to D9, it looked weird - In "diode" mode, I get .150V in one direction, open in the other. When I test it in resistance, I eventually measure 80-90ohms in one direction (it takes a moment to settle), but it's open in the other. It might be OK?"

Next?

Thanks. 73,

Jim KO5V

Thanks, Keith, for the pointer on audio IC U1 on the DSP board.  Visual
inspection shows no obvious sign of overheating on the IC or the DSP board
itself.  Will have to find a thermometer with a fine tip probe to measure
surface temperature on U1 though - household thermometers I have are too
large to fit into that space.

Subject: [Elecraft] One of my most-used K3/K3S/KX3/KX2 features: Per-band
	quick memories
Message-ID: <FC3FE6E6-F852-4D60-A176-F30A05444F0E@elecraft.com>

All of our K-Line and KX-Line rigs include our "quick memories" feature. I use this all the time. In case you missed it, I thought I'd remind everyone how it works.

First: Why do you need quick memories? The general idea is that, on each band, you probably have some favorite starting points (frequencies) in each mode, or maybe a couple of them in a particular mode. For example, on 20 meters I typically start looking for signals on 14005 in CW mode, 14200 in SSB mode, 140083 in FSK-D (RTTY) mode, etc. On 6 and 10 meters I use only CW and SSB, but I have a couple of favorite beacons. On transverter bands, I have some local repeaters I routinely check.

The need for these often-used starting points is what led us to the quick-memory concept. You can store and recall up to 4 quick memories on each band.

Here's how it works:

1. Set up a VFO frequency and mode of interest. (Set up both VFO A and B if you like. I always do this, in effect making each quick memory store two frequencies that I can quickly check by tapping A/B. In some cases I use them as the starting and ending points for scanning.)

2. Tap V>M (on the K3/K3S) or STORE (on the KX3/KX2). 

3. Tap the '1' switch on the numeric keypad. This saves the present VFOs to the first quick memory.

Repeat these steps to create up to four quick memories on the current band, then move to the next band.

To retrieve a quick memory, tap M>V (K3/K3S) or RCL (KX3/KX2).

Harbor Freight Hand held IR laser thermometer is your best friend.
Hold trigger, aim visible light, read surface temperature.

You should be able to listen on the right channel with a second instance if software. Software must be a different folder on computer. I don?t think you can control the sub from this. 

For what you are trying to do you might consider a Flex 6500.

Jim,

Is this KPA100 newly assembled? Or did it work beefore?

Your KPA100 D9 and D10 diode measurements seem to be normal.

Check the orientation of all diodes against the parts placement diagram 
in the back of the manual.

It would appear that you have a short on the 12 volt supply input of the 
KPA100 - due to a solder splash or some other problem.

Look at all points that are labeled 12PA in the schematic.
Your ohmmeter from ground to the + terminal of J3 should show the short.
Any chance that you have assembled J3 backwards?

Don W3FPR

Hi Wayne,

many thanks for that kind reminder.
It looks like cool and useful feature and it works nice on my K3 oldie.
I do not know why I did not used it until now...

I am always happy to read some of these tips and trick from you over here
Wayne.

Many thanks and best regards,

"Ever since I received my KPA1500 (SN 00178), I've observed that the ATU?sometimes won't achieve a match better than about 1.4:1, even though the antenna SWR is well within range."

What is the SWR stop threshold set to.  It's controlled by serial command (^STS) and I assume that, like the KAT500, the value(s) can be set with the utility.

Message-ID: <1951570716.4682.1549554092272@wamui-hamster.atl.sa.earthlink.net>

Don,

I finished the amp a few weeks ago. Both the amp and the KAT100 in the EC2 have been working as they should, and I've made many QSOs, many with transmit times long enough to cause the fan to switch to the high-speed.

When I started looking for this problem, I found the transistor mounting screws loose (Forgot to check them!). After I tightened them up, the amp passed the resistance checks in the manual. 

J3 is correct, I checked the K2's supply voltage at the cathode-end of D9, and measured +12V. It is then blocked by D9. 

When I measured the KPA's power supply's no-load voltage it was at the Power Pole end of the cable, so the fuse and cable should be good. When the power supply is connected to the KPA, I measure 1.5V across J3.

Measuring between ground and J3+, I see a momentary continuity indication. On a higher resistance scale, the resistance started at at >10k ohms, then reduced, eventually going through zero, and then back up to a very high resistance. It looks like the meter might be charging a capacitor (C83?).

I'll check all of the soldering, and the 12PA points.

Thanks! 73,

Jim KO5V

Jim,

OK since you have good voltage at the inside of J3, all should be well 
(did I misunderstand you for the side of J3 that you measured?).

The resistance measured at J3 would normally start out at a lower 
resistance and increase as the voltage from the DMM charges C51. If you 
have a strong light shining on the PA transistors, they will produce 
some small voltage.? Shade the PA transistors and try that measurement 
again.

Since you say that D9 is blocking DC to the base K2, then it must be 
installed backwards.? D9 should conduct from the anode to the cathode, 
but not the other way around.? It is there to protect the base K2 (but 
not the KPA100) from reverse polarity.

Check the contacts on J4 - the spring fingers seen through the 
rectangular holes should have snapped into place locking the contacts to 
the housing.? If you do not see the spring fingers through the 
rectangular hole, the contacts have not been properly inserted.

You should also check the Anderson Power Poles.? Look in the end - the 
contact blade should be latched over the spring finger.? If you can see 
both the spring finger and the contact blade, give the contact blade an 
extra push to seat it.

It appears that you are looking in the radio to solve the problem you state. That is the wrong place. It is the computer software that has to ask the right question.

The CAT interface for Elecraft radios is published and maintained by Elecraft. It is available at the Elecraft web site for download. As an example, to request
the frequency of VFOA in the K3, the computer would send the string ?FA;? to the K3. To retrieve the VFO B frequency, the strings is ?FB;?. The computer sends
these strings. If you look at the document you will see there are many strings that retrieve or set information for the main receiver and have counterparts for the
SubReceiver. It is up to the computer software to use the correct one for their use.

The correct course of action would be to contact the authors of the various software programs that you want to access the sub receiver and file bug and enhancement
reports, asking them to support the features you seek. Again, the solution is not in the radio, but rather in the software you use.

73!

Don,

OK, I again thoroughly checked the PP connectors and the fuse/fuse holder, they're good, so I decided to remove the cable from the power supply, and the bolt negative output of the Tripp-Lite rotated. I opened it up and found the insulating washer was broken. I need to go to the hardware store and get a couple of new washers, but I'll bet that's the problem. It would run my LP100 when it was the only thing connected, but that draws little current. I just assumed the problem was my work - and it may still be! I'll let you know what happens after I repair the supply.

Thanks for your patience. 73,

Jim KO5V

Don,

It is all working again!

The power supply's negative terminal was the problem. The terminal wan't falling off, but the internal side of the plastic feed-thru washer had cracked, and about half fell off inside. That caused it to loosen up slightly. Without the KPA hooked up, it supplied the LP-100 with enough current, and it measured the correct voltage, so I assumed it was OK, and eliminated it.

I also mentioned that I was having trouble getting the K2 to communicate with a logging program, and again, I was convinced that my home-built multi-cable assembly was the culprit. It is now working. I replaced the BRAND NEW 6' long DB9 to DB9 serial cable (purchased from a "large on-line retailer"), with an old one I bought years ago at Radio Shack. 

I have a lot of experience that tells me that I should check my work first, but now I know not to trust everything else - even if it is new.

Thanks again for your help. 73,

Jim KO5V

I've always said "new only guarantees new....not necessarily good".???? 
That's one reason why companies supply a warranty with a new product.? 
They expect some failures and some to be dead out of the box.

Jim,

Glad to hear that you have it solved.
It is necessary to have all power connections tight.

Yes, check the simple things first.  That is a rabbit hole we all fall 
into at one time or another.

Message-ID: <1549629677634-0.post@n2.nabble.com>

Let me start by saying that I am a long term Elecraft customer. I have built
4 K2s and a K1. I also own a K3, K3s, KX3, KX2 and other Elecraft gear. I
helped out for several years as a volunteer in the Elecraft booth at the
RARS hamfest here in Raleigh.

Two recent experiences involving backordered AX1s have left me concerned
because my credit card was charged before Elecraft shipped the product. In
both cases the backorder turned out to be longer than a month. I was not
offered a refund on my credit card until I actually cancelled the orders.
Note this was not a hold of funds on the card, it was an actual charge. In
the first instance the AX1 was part of a larger order which included a KX2.
I was charged for the entire order even though the AX1 did not ship. In the
second instance the AX1 was listed as in stock when I ordered, I was
notified that there was a week delay and then notified the delay was longer.
My credit card was charged on the day the order was received by Elecraft. I
cancelled and am awaiting a refund.

Back in the early days of internet ordering the most important test of a
company's business practices was that they not charge a credit card before
shipment. Amazon is a perfect example of this, they never charge before
shipment. I will allow for some exceptions where I am told in advance that I
am placing a preorder and my card will be charged immediately. Elecraft did
not do this in either case described above.

The bottom line and based on the experiences above, it appears to be
Elecraft policy to charge credit cards before shipment. I am extremely
disappointed with this. Sorry for the long post.

I accidently sent 200 watts pep to the KPA500 input however it did not fault

on high input power. 

Thought I would check here first before calling Elecraft

Lou,

I believe that was an oversight in sales - likely because you also 
ordered a KX2.

I would suggest that you email sales at elecraft.com to question if not 
charging before shipment is still the standard practice.

The only time I have heard that Elecraft has pre-charged credit cards is 
when they offered first shipment priority on the KPA1500 if they pre-paid.

Hi Don,

As I stated, they did this twice so I suspect more than a glitch.

I did try to talk to sales and received several excuses but no definitive
answers.

What, EXACTLY, are you expecting readers of the Elecraft list to do for you?

I am expecting nothing from the list. I am attempting to inform the list
members that at least under certain circumstances Elecraft may charge your
credit card well in advance of shipping. Obviously anyone is free to do
anything they want with this information including completely ignore it.

I had a similar issue recently after ordering a KXPA100. The "Status" page
said they were in stock, both in kit form and completed, so I ordered a
completed one.

I ordered, my credit card was charged (not a hold of funds - charged).
After a week I called to find out the status of my order and was told that
several parts were on backorder and that they were expected the following
week. I asked the lady to cancel my order. She put me on hold and a man
then picked up the call, telling me that the amp is "ready to ship and will
go out today". No thanks.

In retrospect, I believe my order had been lost and would not have been
found had I not called. I didn't like the fact that my card had been
charged - I've been told since that this is not legal - or that the item
wasn't available despite what the Status page said. If they're not going to
keep it updated, don't have it at all.

The whole thing turned out to be a blessing in disguise:

I continue to enjoy my KX2 and KPA500 ;-)

Richardo,

You are looking for something that does not exist.
The Troubleshooting section of the Owner's Manual has a lot of 
information about error codes and steps to correct it.

Hi Jack:

I hit mine with about 100 watts. Had a great exchange with support along
with some over-email troubleshooting. Even though they think they
pinpointed the issue and I should be able to replace the component I
decided to return it for the repair and a good going-over.

Hi John

Interesting story, but without someone from Elecraft jumping in, we are
just guessing.

I suspect it went like this, as I have some experience with online stores.

You placed your order, and the funds show on your credit card as you
ordered.

What you can't tell if the funds are on hold or not.  Those funds may not
have been captured (transferred to their bank).  A hold can last about 3
days before it expires.

If you called your credit card company and they said the funds were
captured, then I guess they were.   The capture is a manual process.  Maybe
they did, maybe they didn't.  But, what is key is the vendor (Elecraft)
takes ALL the risk on a credit card order.   It is easy for you to contest
a sale and the first thing the Bank does is go steal the money back out of
the Vendor's account.  I have seen this happen up to 8 weeks after a sale
to several of my friends who run small hobby businesses.  It is so bad,
they are going to shut down their small online business due to this type of
fraud.

So, next you call and say cancel.  What happened is they likely  jumped
through hoops to save your order and not lose a customer.   Parts missing
could be as simple as a knob or a washer.   Maybe they run over to
HomeDepot. :)

I doubt your order was lost but I do believe the delay was valid.  This is
normal for companies like Elecraft as they build to sales demands.

Elecraft is a very awesome  company and run by some wonderful people.
There is no doubt in my mind they were not trying to scam you or pull the
wool over your eyes.

I have had my share of Credit Card horror stories as I order a lot online.
I have yet to loose a single penny out of my own pocket in 30 years.  In
the 2 times I have issues, Visa quickly refunded my money without
question.

Like I said, it is the vendor that takes all the risk, not the buyer.

Nope, never meant to imply that they were.

And yes, they are an awesome company - I've owned one of every major item
they've ever offered except a KPA1500. Just relating my experience, and I
should also note that my CC was refunded quite speedily.

This is an issue that should be addressed directly with Elecraft management.? Obviously it is not an issue that everyone is having - I haven't with anything I've ordered.




This is really not a buyer beware issue.

I?d like to add my 2 cents.

Last year I was fortunate to call and arrange a visit to Elecraft.  The Elecraft Team welcomed me and Cody of Elecraft gave me a 1 hr tour where I got to meet nearly every Team member and was able to speak with each of them 1 on 1.

Every person took an avid interest in me and the Elecraft rigs I owned and offered to help me with any questions not only while I was there but also encouraged me to call them when I got back home.

I can tell you from 44 yrs experience in electronic manufacturing that Elecraft is a precise, transparent, well run and personable company that takes a genuine interest in their customers.  They made me feel not just like a customer but like a Team member.  They are as we say ?good people.?

No company is perfect but from my personal experience with Elecraft in previous pre and post sales and technical support contacts they are the BEST.  

The time and personal attention they showed me just further reinforced the great Elecraft Customer Experience we all get when we turn on 1 of their rigs.

If you ever have a chance to meet up with any of them please do so and then send the company some pizzas as a thank you for being Elecraft, a company who makes us feel like a member of the Team.

You are looking for something that does not exist.
The Troubleshooting section of the Owner's Manual has a lot of

The books by Fred Cady, KE7X  contain a lot of detailed information on the circuits and how they operate that can be of use in servicing the rig.

Great response Wayne.  This should either be corrected or the purchaser
clearly informed at the time of purchase. FWIW, Credit cards typically offer
90 days of protection.

Subject: [Elecraft] Firmware Release Notes for K3/K3S Beta 5.67
Message-ID: <emb5be2cf7-f564-44fd-9c51-c8fce81fc9af@paul-pc>

A quibble and a question regarding firmware beta version 5.67 for the 
K3/K3S,

The firmware notes state that
"1 dB below 100 W is approx. 90 W."

In fact, 1 dB below 100 W is a shade less than 80 W.

The firmware notes also state that
"T/R TIMING IMPROVED. Adds more margin during KPA3A TX sequencing."

I would like to learn whether the T/R timing change will affect also my 
KPA3, and in what way.

73, Paul W8TM

Tom Hammond N0SS designed and marketed a small simple-to-construct board to
fit inside a K2 to key an amplifier. Tom became SK several years ago and
the boards are no longer available. I have found a source which will make
the boards but I would have to buy in large quantity. Who might be
interested in buying one about $5 postage paid to the USA? If I get enough
interest, I will get a bunch.

John,

it is the same with all transceivers. In standby everything is OK and 
input power is shown on the KPA screen. But in operating mode the signal 
blocks somewhere. The RF of the TS590S doesn 't even switch the band 
filters of the KPA while it does switch them in standby mode. I suspect 
the input relay or circuit. There may have been DC in the coax line 
caused by a remote beverage switch.

The amp shows 0.5 Ampere current when PTT is applied. Not very much so 
there may be more trouble.

CU all in the PACC, starting within a few hours!

I would very heartily agree.  I have the Cady manual for all my Elecraft (all the radios that he wrote a manual for) radios and they are a joy to use, not only for info on the specific radio but also the extra info that is helpful to any ham.  His trouble shooting lists for "when you can't make a contact" are invaluable for ANY radio, Elecraft or other.  Also his latest book about everything a ham radio operator needs to know is a joy to read and a great refresher to this guy who has been a ham since 1960. I will buy anything he writes in the future.  Check out his list on the Elecraft site or Lulu Books.  (I am not related to Fred.  I just like his information and style of writing.)

Message-ID: <CA+h_a7KcyngcQy3+ByzhyhO236nQjayw7hEr0Mnu+Q3_YDrurw@mail.gmail.com>

I did my first travel with my remote setuo (K3/100 and remoterig) and i was
thinking to minimize the cabling and size of the setup.

A lot of gear and cabling to do, so went to my mind, the idea of a K3/0
Mini with a kind of remoterig INSIDE and most of the cabling already made

So K3/0 Mini cable set, will be already connected inside

Paddle integrated on the "new" K3/0 Mini

You will control CW speed with K3, so no need of remoterig CW pot

Mic integrated on the "new" K3/0 mini, a telescoping boom to reach your face

Just need to connect a pair of USB cables to the laptop and is ready!

Of course this will need some work togheter from Elecraft and Microbit, but
would be very good to have this simplified for the user

Thanks David and David.  The Elecraft books and "The Successful Ham Radio Operator's Handbook" have been fun to create and employ many of the things I learned in 40+ years of teaching EE students.  The main Elecraft product books (K3s, KX2,  KX2, KPA500/KAT500, and Macroprogramming) can be found at https://elecraft.com/collections/books.  Other Elecraft product books and "Successful..." are at www.lulu.com<http://www.lulu.com> (search for KE7X).  See www.ke7x.com<http://www.ke7x.com> for more information.


As of this morning Lulu has a 15% discount on print books (code LKAB317CD).  I think it is only available for print books and not the pdf versions.


BTW, Vic VE3YT and I are in the early, early stages of thinking about a book tentatively called "The Joy of Building".  We hope it can encourage people to build something and experience the joys that we felt in our early days and which continues today. Content suggestions welcome.


Cheers and 73,

Fred KE7X and Vic VE3YT

Well

now I know, that in 2013, Microbit made a PCB which fitted into the K3/0
mini with all included, even Wifi,

Would me good if Elecraft take again this and now do something about it

PCB is working, Microbit CEO use it

Message-ID: <ACA10A2F-93A2-4EB5-B7F3-3A69E8381D8E@gmail.com>

I recently bought and built the T1 ATU, and it works great - no issues from first power up on.  I should say it functions correctly - but I have a problem with the battery voltage displayed by the ATU.  It seems to be over 1V high.  I don?t expect calibrated precision, but a semi used 9V battery is being displayed as(mores as) 10.3+ V?  Is something wrong and if so any ideas?  I have checked the values of all installed components that I believe are related to this circuit meaning specifically everything on the control board.  I am concerned that when the battery is getting too low, The ATU won?t know or warn me.

Thanks

Will,

Are you using DATA A mode?  The normal sideband for DATA A is USB which 
works with most all soundcard data modes.
If you are using USB mode instead, I suggest you change.  Using Sideband 
mode for data modes requires you to turn off compression and set the 
equalizers flat - DATA A mode does that for you automatically, leaving 
your sideband mode settings intact.

Do you have any of the audio levels set to an extreme setting?  They 
should all be set within mid-range.  The application "power" slider, the 
soundcard levels and the K3S Line level are the ones of concern.

Are you driving the K3S with sufficient audio.  You should have 4 bars 
solid with the 5th bar flashing on the ALC meter.  See my article on 
that subject at my website www.w3fpr.com for a full explanation about 
setting the audio levels for soundcard Data modes.

Will,

I answered without reading carefully enough - most questions of that 
sort are about FT8.

With RTTY through a soundcard, you should be using AFSK A mode.? It 
defaults to LSB and my comments about DATA A mode otherwise apply.

If you are keying the FSK pin in the ACC connector, then you can ignore 
the audio levels, but you do need to convert the level to TTL voltage 
levels (+5 volts and ground).? If using that input, the K3 mode should 
be FSK D.

The KPA500 has two serial ports.  One is assigned to PC and the other to transceiver.    I'm aware that all the commands in the Programmer's Reference can be used over the PC port and have been using this interface for about a year for my data logger.

Does the transceiver port also support the full command set of the Programmer's Reference?    If so, does any special care have to be taken when sending the same interrogation or command over both ports?

No. The transceiver port is meant to receive data from a connected Elecraft or Kenwood transceiver. It acts on data responses received from those devices.
Specifically, it is looking of the following command responses from the transceiver: FA;, FB;, FR;, FT;, or IF;.  The entire purpose of the XCVR port is to provide another method to obtain the operating band from the transceiver.

When it is set to poll the transceiver for data, it sends the following sequence: IF;FA;FB;

If you send any KPA500 commands, as described in the programmer?s reference to the transceiver port, they will be ignored. Likewise transceiver responses sent to the PC port will also be ignored. It is significant that the transceiver port uses a male DE9 connector - the same as used on a standard PC, While the XCVR port uses a female DE9 the same as used on peripheral equipment..

Page 4 of the KPA500 operating manual alludes to the differences in the two ports. For the XCVR port, it states: "RS232 (XVCR) connects the KPA500 to a Kenwood transceiver using a standard 9-pin serial cable. This connector cannot be used to update KPA500 firmware (see pg 20).?.  While for the PC port the text is: "RS232 (PC) connects the KPA500 to your personal computer with a standard 9-pin serial cable. Required for updating the KPA500 firmware.?.
The important piece of information here is the update text. Firmware updates, and other control commands, must be sent to the KPA500?s PC port. Sending them to the XCVR port will do nothing as far as the amplifier is concerned.

The DC should not have done anything - the KPA blocks it at its input. But the excess power apparently did quite a bit of damage. Call the tech support guys on Monday.

Good luck in PACC. Most of us contest types in this area (Northern California) are operating WPX-RTTY this weekend.

The RF of the TS590S doesn 't even switch the band filters of the KPA while it does switch them in standby mode. I suspect the input relay or circuit.

If you purchase the K60XV transverter board for the K2, you can use it to get a key out for an amplifier.
The 2N7000 transistor on the K60XV is used to switch the key out. The 2N7000 can key most amplifiers in use today.
This is how Don converted my K2.

Tom Hammond N0SS designed and marketed a small simple-to-construct board to fit inside a K2 to key an amplifier. Tom became SK several years ago and the boards are no longer available. I have found a source which will make the boards but I would have to buy in large quantity. Who might be interested in buying one about $5 postage paid to the USA? If I get enough interest, I will get a bunch.

Thanks Jack.  I suspected that would be the case but it was better to ask than to waste my time experimenting.    I'll just have to put a bit more thought into how to configure the KPA500 polling devices and the associated serial data multiplexing relay(s).

I will soon have a K3S and I?ve been in the market for a boom mic set for the shack. This will be my first boom mic. I?ve checked out the Hiel site and could not find any complete packages. Everything is sold in too many subassemblies. I?ve tried emailing them but no reply. Our local ham store (radioworld.ca) only sells in pieces as well.  

I?d prefer a tried and tested set ready to go boom mic set for the K3S. 

Any recommendations? In this case value (performance and longevity comes ahead of price) for me. I plan to keep this station for a long time.

Yamaha CM500 plugs straight into the rear panel mic and headphone jacks, 
sounds great and is very comfortable. You'll need to turn on bias for 
the mic (see the manual, simple menu settings). That will mute the 
speaker, so most of us assign <SPKR + PHONES> to one of the PF buttons. 
I use PF2.

Brian,

Have you checked the Elecraft website.  The Heil ProSet-K2 is complete 
and includes the adapter which allows it to be plugged into the 
K2/K3/K3S Front Panel 8 pin mic jack and headphone jack.
Without the adapter, it can be plugged into the K3/K3S rear panel mic 
and phones jacks.

You need to buy in large quantity to just have a PCB made or are you talking 
about quantity needed for getting the board made *and* stuffed?

If you just need the PCB's made there are a number of choices available. 
I've used OSHPark and Elecrow. Go to http://pcbshopper.com/ to see what 
options are available for bare PCB as well as PCB assembly.

The Yahama C-500 and the Koss SB-40 are two good ones.?? Not expensive 
but comfortable and good sounding for both the mike and the earphones.? 
Either works very well with the K3S.?? I know, I have all of them.? My

This is an excellent headset at a reasonable price. In a gaming headset with a mic, the tip and ring are shorted together and you can plug it into the rear of the K3s. You cannot use Heil's adapter for the front panel Foster 8 pin connector on the K3s because they short the ring to the sleeve for some unknown reason. So in order to use the K3s front panel 8pin Foster socket, you need to make your own Foster to stereo mini phone connector adapter. Only two connections and DX Engineering has an excellent Foster plug. Ignore the reference to Heil Replacement Part, it's just the same old Foster 8 pin plug for all mics and rigs.

The only issue with CM500 is the ear pads eventually wear out. I've had mine about 10 years and they're still serviceable, but on their way out. For the low cost, replacing them every decade isn't horrible. 

It's clear these are an OEM product made for Yamaha by Koss. Koss sells replacement pads for their headsets $5 with free shipping. Has anyone figured out the correct crossover Koss model to get compatible pads?

The Koss SB-40 is essentially a Yamaha CM500 with a dynamic mic instead of an electret mic. Some people really don?t like the dynamic mic in the Koss SB-40. I?ve heard zero complaints about the electret in the CM500.

The Koss SB-45 is a completely different headset design that does have an electret mic. It sells for $25, much less than the CM500 ($60).

To muddy the waters further, my Yamaha CM500 has ?KOSS? molded into the microphone plug.

Josh, 

Regarding ear pads for CM500, I ordered these from eBay, $13.49 including shipping: 

Replacement ear pads cushion earpads pad cover for KOSS UR20 UR 20 headphones

Suggested by another Elecrafter.  The ear pads fit and are just a fraction of an inch large, and work just fine.

Everyone so far has recommended a headset with ?boom@ mic. 

I wonder if you mean a mic on a table mounted ?boom??

From the options you describe, I think this might be the case. 

I have a Heil PL-2T boom with a Heil SM-1 Shock mount with a Heil HM-12 mic. You?ll also need a cable (use Kenwood config) and some form of PTT if you don?t use VOX (an unused J-38 works well). This sounds good on with my K3S and K3.

In that case, I have used one of these for a decade or more. It supports up to 8 pounds and doesn't make noises when you move it with a live mic.

Same here.  Most of the spring loaded ?booms? sold for the ham market are pure junk ? wimpy springs, fall apart, basically cheap lampshade holders.

Yes, I've heard the complaints about the Koss SB-40.?? I've used mine 
with great audio reports {even the AM fellows approve} and I've 
critically listened to the radio using the SB-40.?? For those that have 
gotten bad reports, the solution is very simple.?? It is known as "mike 
technique".

The placement of the mike is very critical.? Funny as it may seem, place 
the mike about 1" off of the end of the nose.? Never below it, and never 
below the chin, and never in front of the mouth.?? It is a dynamic mike 
which does exhibit proximity effect. ? A known fact. ? Below the nose 
and one "snorts" like a bull as they exhale.?? Below the chin and the 
breath pops are excessive as the upper lip and roof of the mouth directs 
the burst of the "P" downward.? Plus it will get baptized when one 
drinks coffee.?? At the end of the nose, there's no snorts, there's no 
breath pops, there's no proximity effect, and the element doesn't build 
up spittal. ? And one can still drink coffee without giving the mike a 
baptism.

As to EQ, and this applies for the C500 as well, just roll off every 
thing below 200 Hz to -16 dB and 400 Hz about -3 dB to -6 dB.? You'll 
sound like Don Pardo.......assuming you have the pipes.

Good Evening,

 ?? The WPX RTTY contest is running through tomorrow.? They will finish 
at the start of the forty meter net.? But they may be filling much of 
the CW portion of the band plan earlier in the day.? If I can find an 
open spot between them I will start the twenty meter net.? If I have to 
move too far off the stated frequency it becomes very difficult for 
anyone to find me.? So as ever we'll play it as it lies even if there 
are leaves, pine straw, and sprinkler heads.

 ?? The regional weather has become interesting.? There is more snow at 
lower elevations than there is up here.? The forecast gives me a nice 
range of snow fall for the next few days. Anywhere from 2 inches to 4 
feet.? I think someone is throwing darts at a forecast table.

Please join us tomorrow on:

14050 kHz at 2200z Sunday? (2 PM PST Sunday)
 ?7047 kHz at 0000z Monday? (4 PM PST Sunday)

73,

 ?? Kevin. KD5ONS

I have not seen, and google did not reveal a picture of a K3 with a 
KPA1500 alongside. Plenty of the KPA500 with a K3 but none of the 1500. 
I would like to see the amp and radio side by side both with the tilt

maybe a QRZ page with them on?

Subject: [Elecraft] 5.66 Line Out Problem
Message-ID: <3b02f214-4ff7-cf50-a7a7-e18f4ce36cbe@tx.rr.com>

I just fired up the K3S to do a little listening in the WPX RTTY 
contest. I noticed that the line level signal being piped from the radio 
to the sound card (microHAM MK2R+ Audio Codec) was changing as I 
manipulated the radio audio gain control. I checked and the LIN OUT was 
set to NORMAL. Toggling it to =PHONES made no difference. It appears the 
LIN OUT function is permanently stuck in the =PHONES mode. It's been a 
while since I've used the line output, but I know the line out level 
used to stay constant regardless of audio gain pot setting. I've 
recently updated to the 5.66 firmware, so could it be there's a problem 
in this function that's crept in somewhere in the last few FW releases? 
Has anyone else noticed this?

My first thought was that you were asking about a "studio type boom" for 
your microphone.  If so read on, if not delete now.  I bought the PSA1 
boom from R0DE on Amazon for a decent price.  Mine came with both the 
edge clamp base and the "cone" base for putting in a hole drilled into 
your desk.  Mounting it on the edge of the station desk was very very 
easy.  One day I may get around to drilling a hole.

http://www.rode.com/accessories/psa1

I have used the R0DE PSA1 boom for the last 3 years and it has worked 
very well with zero problems on holding the mic wherever I want it nor 
has there been any problems with the clamp holding firmly to the edge of 
the station table/shelving.  There is a weight spec for the microphone 
that is to be used with the boom so be sure to look at that.  Buy the 
boom, put whatever XLR mic you want on it and buy the Heil XLR cable 
needed for your mic and radio.  You're then done with the hardware and 
it's just a matter of setting up your mic in the radio.  I have used the 
Heil PR781 and a nice Shure on the boom with no problems.  Good luck.

Heil sound has a wide selection of mics and booms. Bob even has 
recommended starting points for the K3 TX eq settings. You can buy them 
from Bob, or you may find a lower price from a dealer.

Please reread Martin's original request. He's asking for a pic of the K3 
and a KPA1500 next to each other, not simply a pic of the KPA1500. The 
QST pic is of the amp alone. The pic at the bottom of the page is of the 
K3S with the P3 and KPA500. Plus, Martin is in Thailand. Even if the 
page 19 QST ad actually showed what he was requesting in his original 
post, it is very likely that he isn't a member of the ARRL and doesn't 
get QST.

Tom -

You referenced P. 21 of the February QST and Bill - KC4IM referenced P. 19
of the February QST. Page 21 of the Digital version and P. 19 of the print
version show the KPA1500 on the upper half of the page, with the K3, P3,
and KPA500 on the lower half of the page. I find no picture of the K3 next
to the KPA1500 which is what Martin is looking for.

Hopefully, some reader who has the K3 and the KPA1500 can send Martin a
picture of what he wants to see. Or, perhaps Elecraft can supply that.

The point a bit confusing to me was the expression "boom mic set".?? Is 
the requirement for a mike boom and a mike with a cable??? Or is the 
requirement for a headset, which I take to be headphones with a mike on 
attached boom?

I've one of these desk booms I've used very satisfactorily supporting my 
Heil PR-781 which is heavy and the Shure SM-58 which is much lighter.? 
While it offers two mounting systems, I opted for screwing the base onto 
the surface as opposed to the clamp-on mounting.

https://www.amazon.com/LyxPro-Adjustable-Microphone-Suspension-Scissor/dp/B075MS16S8/ref=sr_1_10?crid=1NIJNRZDYU1N3&keywords=microphone+boom+arm&qid=1549858083&refinements=p_72%3A2661618011&rnid=2661617011&s=gateway&sprefix=microphone+boom%2Caps%2C283&sr=8-10

As to mikes, connectors and cables.? I choose to buy a good quality 
Amphenol XLR connector and a Foster 8 pin connector and a bit of 2 
conductor shielded cable and make my own.? I find this combination much 
more reliable and much less expensive than the adapters.?? And I believe 
more connectors and adapters in a signal path equal more problems.?? 
Thus 2 connectors and one cable is highly reliable.? FYI - Has been this 
way in the recording studio environment for years and years.

"I wonder if you mean a mic on a table mounted ?boom??  Correct!

From the options you describe, I think this might be the case.

I have a Heil PL-2T boom with a Heil SM-1 Shock mount with a Heil HM-12 mic. You?ll also need a cable (use Kenwood config) and some form of PTT if you don?t use VOX (an unused J-38 works well). This sounds good on with my K3S and K3.

Yes this is exactly the info I was after!        

As for PTT I use an old dictation machine foot pedal. 

Bill as my K3S has not arrived yet I?m wondering which cable as I?m not sure what type of jack the K3S mic-in is..

- Heil HSTA KM For Kenwood modular? 
- or Heil HSTA K8 For Kenwood 8 pin?

Much appreciated.

Thanks

Best advice.........down load the K3S manual from the Elecraft 
website.?? You'll need to read it 3 or 4 times before you get the 
radio.? It has info about all the connections, front panel and rear 
panel. ? And will familiarize you with the menus and controls. ?? It is 
easy to understand and only 90 pages including a GOOD index.

Otherwise like many hams........get the radio, connect a bunch of wires, 
cram connectors in places which they look like they fit, turn it on, 
turn lots of knobs, push lots of buttons, change things 
and.........wonder what in the heck they did to make it stop working.

Strongly agree, EXCEPT that, for nearly 30 years, Switchcraft and 
Neutrik have OWNED the market for pro audio connectors because of their 
exceptional quality AND their very nice redesigns to make them a LOT 
easier to terminate. Amphenol is still big in some RF connectors, but I 
don't remember the last time I saw an Amphenol XLR that wasn't at least 
30 years old. BTW -- for almost that long, I've been a member of AES 
Standards Committee Working Groups, including ones that address 
Microphones and Connectors.

The Serial Box <https://bit.ly/S-BOX> (S-BOX) was specifically designed to
make it easy to connect multiple devices in parallel to any transceiver's
serial port, including a PC, KPA500, KAT500, KPA1500, SteppIR Controller,
Kessler AT-Auto, Shackmaster SM-8, etc.   One device is connected to Pin 3
(usually the PC running logging software to do the polling), and the rest
are wired in parallel to listen to the radio's responses on Pin 2.
AutoInfo mode may also enabled to let all devices track the transceiver's
frequency automatically when no PC or logging software is being used.

My configuration requires one device to be the routine polling device but has to allow for another device to break that polling interface and insert different commands to the destination equipment.

E.g - 1. OmniRig polls my TS-590 and my TS-590/Elecraft interface listens to the responses.  When I want to set the TS-590 power, or initiate a TX Tune, my TS-590/Elecraft interface disconnects OmniRig, attaches the local RS232 source, sends the power command, then returns control to OmniRig.    The supplemental commands are timed to only be sent in the "window" where OmniRig is not sending a command.  (It's actually a bit more complicated than that because initiating a TX Tune first inhibits the amplifier key line then, when key inhibit is confirmed, it initiates TX Tune with a specific power setting,  returns TS-590 to receive mode, waits until RX mode is confirmed, then re-enables the amplifier key line.)

E.g -2.  The KAT500 utility may be polling my KAT500 but I disconnect it and send the KAT500 commands to change L, C, bypass, antenna side, etc.  Again this is is done without disrupting KAT500 utility polling as the commands are only sent in the "window" between the utility polls.   Depending on an option setting the TS-590/Elecraft interface can be the primary KAT500 polling device and the utility is not needed.

Examples 1 and 2 were implemented a while ago and are mature and reliable.  The next step is to integrate the KPA500 so OPER/STBY are fully integrated in my power control scheme.

So, sorry, but your interface doesn't come close to meeting my requirements.

Message-ID: <1718825352.12124.1549915795258@wamui-moana.atl.sa.earthlink.net>

I've had this kit for several years, and I finally built and tested it last week. It works well to reduce the band noise, and there are a LOT 
of adjustments - which is the problem for me. I have been using a friend's DSP speaker that has a knob, and for my simple mind, it is easier
to use. However, for someone who likes to fiddle, this would be a great solution, IMHO.

So, I want to sell the DSP module. I will ship it with the DSP board in static-proof foam, and I have the manual, standoff, mounting screw,
and 5 and 3 pin headers for the control board.

I am asking $150.00 including shipping, or make me a reasonable offer.

I also have a set of the Rework Eliminators pc boards WITHOUT any components. They are still together in one board: UN-K160RX, UN-K60XV, UN-AF2/DSP2,
UN-KSB2 J9 and J10, UN-KSB2 J11 and UN-KNB2. $10.00, including postage.

Please email me off-list, and I prefer PayPal.

Andy,

You are dealing with an RS-232 communications protocol, which is only 
point to point and not multipoint like Ethernet.

I have no idea how your "polling" device works, but with RS-232, there 
is no polling, it is direct "handshaking" between 2 devices, a DTE and a 
DCE.  If handshaking is implemented, Data Terminal Ready, Data Set Ready 
are exchanged, then Request to Send and the Clear To Send Response are 
sent.  That signalling protocol is normally used only by modems.

Most ham applications do not use those handshaking signals, but rely 
only on Transmit Data and Receive Data to establish communications.

For RS-232 there MUST be only one transmitter - there can be multiple 
receivers, but those devices (other than the main one, either the PC or 
the KPA500) can be the transmitter.  It takes some complex hardware 
device to switch an RS-232 bus from one transmitter to another.

This is a hardware consideration and has nothing to do with software 
such as OmniRig.

Consider the RS-232 voltage levels and you will see why there can be 
only one transmitter on a line.  The active level is between +3.5 volts 
and +25 volts while the inactive level can be from -3.5 volts to -25 volts.
Think about what happens when you connect one device producing +25 volts 
directly to the output of another device producing -25 volts!  That is 
why only one transmitter can be used on an RS-232 signal line.

There are several devices that can be used (such as the SteppIR 
controller) in an RS-232 environment, but their configuration must be 
set to only listen to the traffic on the main RS-232 communications 
which is normally the PC and the transceiver.

The S-Box has the transmitters hardware disabled for all but one port - 
that is how it allows multiple devices to listen in on the communications.

"I have no idea how your "polling" device works, but with RS-232, there is no polling, "

Point 1 is true. Point 2 is, in my opinion, not true.

A poll is a request for information.  The device issuing the poll/request is the polling device.   For example, sending IF; to a TS-590 is a data request, or poll, for the current IF status.  The TS-590 responds with the full IF word.

I think the point is that RS-232 does not, as a protocol, support 
polling. Nothing prevents you from doing some sort of polling 
programmatically. However, multiple devices on a single RS-232 line is 
beyond what the protocol was designed for. That's why there is RS-485 - 
which IS designed for multi-device control.

Andy,

"Polling" normally refers to a situation like Ethernet and others where 
a response from a particular *addressed* device is requested.
For RS-232, it is "handshaking" (if implemented) telling the DTE when it 
is OK to send data - since there is only one transmitter on an RS-232 
signalling line, there is no need for addressing. The transmitting 
device expects to communicate to only one receiving device on the other 
end (although other receivers can 'listen in'.

I have worked with RS-232 for over 35 years both professionally (both 
modems and DCEs for 20 years) and with ham radio gear and PCs after 
retirement from that life.

If we wish for clear communication, the terms used are important. Ham 
Radio "speak" often confuses the proper engineering terms. You hear of 
ham radio software that "polls" the radio - in reality, it is simply 
issuing a command to the radio and expects a response to that command.? 
That is a command/response scenerio, and is not really polling.

Not wishing to get into an argument but consider Binary-Synch, Uniscope or UTS400 protocols. They are poll and response, RS232c communications systems. Used from mainframe to (dumb) terminal. They are synchronous RS232 of course rather than asynch and so use the clock and other signals ignored by the [IBM PC] cut down implementation of the RS232 connector. RS232 of course only defining the names and voltages on the connector.

From memory a Uniscope (U100) ?poll? from the mainframe would be the characters: sync, sync, sync, sync, SOH, RID, SID, DID, STX, text, ETX, BCC. 

Now that was dug out of the 1970?s if nothing was!

Hi Don thanks for this.

I?m in Canada and I finally went to Radioworld.ca <http://radioworld.ca/> who is our Heil dealer. 

With the great response I got from this group and input from them this is the order they put together for me?

HEI-HM12 Desk Microphone using Heil Sound Standard CC-1 Connecting Cable System 
HEI-SM1   Shock mount for boom microphones 
HEI-PL2T  Proline balanced arm with topless boom mount 
HEI-DT1    Flush mount for desktop mounting of the PL-2T. 
HEI-HSTAK Adapter cable, traveller to Kenwood 8 Pin (remove)

I?ve just put a question into them about the cable that goes from the mic, through the boom and into the 8 pin Kenwood adapter cable. How does this order look?

Not sure if a ?traveller cable" is part of this or I need to order a separate one. Doesn?t look like it from the website. 

As for Bob being away, that?s fine. I?m just surprised he would not have put an auto reply message letting anyone know he?s away. That would save folks from being left to flap in the wind never knowing if a reply will ever come.

Unless I?ve missed something he?d probably sell a lot more of these things if he took some of the friction and guess work out of configuring and ordering for those of us without a commercial broadcast history. 

I just tried calling in but all the technical staff will not be back from Florida yet but it sounds like I need a.. 
HEI-HSTAK Adapter cable, traveller to Kenwood 8 Pin  

and not the HEI-HSTAK Adapter cable, traveller to Kenwood 8 Pin. Oh and when they say modular cable they mean an RJ45 connector. 

Phew!

Thanks,

Brian ve3bwp

Andy, in support of your comments I was an active Bell System DATEC representative back in the 70s and 80s and multipoint polled RS-232 was very common here in the colonies :)

Subject: [Elecraft] How to save your ears when AGC is OFF (K3/K3S/KX3/KX2)
Message-ID: <3ECEB6C7-F9C1-45B3-83E0-9B1355BC9FD4@elecraft.com>

Here's another feature available on all of our newer radios: the AF limiter. 


Background
----------

AGC (automatic gain control) keeps the AF output level of a receiver relatively constant over a wide range of RF input levels. Most operators keep their receiver's AGC on at all times, so there's no need to "ride" the RF gain control.

However, some operators prefer to turn AGC off. When AGC is off, you experience the full dynamic range of received signals, which can help separate signals from each other, or just provide a more "lively" receiver sound completely free of gain adjustments. But in this case you *do* need to manually adjust RF GAIN to keep signals in a comfortable range.

The problem with this operating style is that extra-large signals can pop up unexpectedly. You might not be able to manually react fast enough to keep them in a comfortable range. This is the reason for the AF limiter. 


Setting Up the AF Limiter
-------------------------

The AF limiter is set using CONFIG:AF LIM (K3/K3S) or MENU:AF LIM (KX3/KX2). The default value is "NOR" (normal), which puts the limit threshold very high -- around the point where the AF amplifier chain itself would cause limiting (extremely loud). So if you plan to turn AGC off, you'll need to set AF LIM lower. 

A good approach is to start with AF LIM = 23. Then turn off AGC (see below), and see if you feel that the limiter needs to come on at a weaker signal level (lower number), or stronger (higher number). The manual recommends a range of 17 to 23.


Turning AGC Off
---------------

- On the K3 or K3S, hold the AGC switch (the yellow label is "OFF"). 

- On the KX3 or KX2, set MENU:AGC MD to OFF.

In both cases, this will change the AGC icon from "AGC-S" or "AGC-F" (AGC on, Slow or Fast) to "AGC-" (AGC off).

With AGC off, be prepared to adjust the RF GAIN control, and don't forget to adjust the AF LIM value as described above.

What ever happened to the idea of making ones own mike cables? Two 
connectors, plus a length of 2 conductor shielded cable and a bit of 
careful soldering, specially on the Foster plug.??? Just use a good 
quality XLR connector such as Cannon or Neutrik.? It isn't "rocket 
science" and it is much less expensive than buying an expensive cable 
plus and adapter and trying to figure out why it doesn't work.?? All of 
the drawings and information is in the manual.?? And for less than $10 
you will have a good quality working cable which is the exact length you 
need and a project for which you'll be proud.

If you don't feel you are able to do this, then check with some of the 
members in your radio club.

Headset and boom mic preferences are a very personal thing, subject to 
our operating style, shape of our head and ears, whether we want to be 
locked in position in front of a boom mic, are well enough coordinated 
to use a foot switch, or even have illusions of a "real radio station."

My personal choice is a headset with a boom mic and VOX, and the CM500 
fulfills that need. If I were going with a mic on a boom like you're 
describing, the mic would be an RE11, RE16, RE18, or RE20. They're 
dynamic mics and nearly indestructible, so it's quite safe to buy one 
used from a trustworthy source. The RE20 is quite popular with talk 
jocks. As far as ham radio is concerned, it is massive overkill, but it 
does look impressive. :)

Because I worked in pro audio and did a lot of music recording, I own a 
bunch of RE16s and RE20s, as well as AKG boom stands. Before W6XU 
introduced our contesting club to the CM500, I used an RE16 on an AKG 
boom stand.

I consider Heil products to be poor quality and wildly overpriced for 
what they are.

The SSB net meets on Sundays at 14.303.5 at 18:00Z. If there is a contest or some other event is going on we will not hold the net. It is pretty regular even if the conditions of late have been bad. We have relay stations to try to reach stations that I do not hear. Even with relays it can often result in some missed stations. Just keep trying. 

I do not get a chance to send a notice prior to the net. If I am not able to do the net, I ask for some fill in help from the other stations. 

Everybody is welcome. So please join us on Sundays at 18:00Z.

I investigated the Heil Foster adapter and the shorted ring-sleeve is inside the 1/8 inch phono jack. Not in the easily fixed Foster plug. So it cannot be fixed...reasonably. Why short it making the adapter unusable for the excellent and reasonably priced gamer headsets?

I have been trying for several months to get WAN to work properly on my KPA1500.  Numerous contacts with Elecraft support have not yielded any solutions.
Even with the Amplifier left ON, the remote software will not connect properly on WAN.

There is some discussion that WOL (wake up lan) is the problem.  I know routers were never designed to pass WOL.  Again, even if I leave my amp ON, it still doesn?t connect.

My solution, thus far is to use Team Viewer with on a dedicated computer and connect via USB.  Team Viewer is much more stable and easier the Remote Desktop.

I am very disappointed this expensive amplifier doesn?t work as advertised?..   Burl ,  AJ9Q

Chuck,

The solution is easy (in my mind).  Just plug the TRS plug into the 
K3/K3S rear panel mic jack.  That jack is a stereo type, but the ring is 
not connected to anything.  No adapter required.

If you want to use the front panel 8 pin Foster jack, you will have to 
build you own adapter.

All microphones that are designed for computer (gaming) use have a TRS 
plug - but the tip and ring are wired together.  That includes the much 
used CM500 headset and many others.  Yes, when used with Heil adapters, 
they will not work because the ring is shorted to the shell.  The Heil 
adapters are designed for mono plugs normally used on the Heil headsets.

73,
Don W3FPR

Don, it also seems obvious that the 1/8? TRS female, use by Heil on their adapter, with the ring shorted to the sleeve serves only one purpose.  That would be to prevent using less costly, higher quality gaming headsets with their adapters.

Hi Martin;

When I received the requested photo of a K3 and a KPA1500 from Elecraft, I realized too late that the amplifier was a KPA500, sorry.  Margaret and Madelyn from Elecraft noticed the error and sent me a photo that is correct, whew!  But, this reflector would not publish it, since it was a bit too large, so I uploaded it to my SmugMug photo account.

Here is a link to that photo ?> https://jrquark.smugmug.com/Amateur-Radio-Stuff/n-gj25kF/i-RXwvZmb/A <https://jrquark.smugmug.com/Amateur-Radio-Stuff/n-gj25kF/i-RXwvZmb/A>

Right! I did end up buying a couple of Heil "Replacement" Foster 8 pin Plugs from DX Engineering. They, by the way, are excellent plugs. Much higher quality than the run of the mill that one finds at hamfests. And I made my own adapter.

Subject: [Elecraft] KPA1500 vs SPE Amps
Message-ID: <mailman.43.1550007893.2815.elecraft@mailman.qth.net>

Has anyone had experience with both the KPA1500 and any of the current (1.3K, 1.5K or 2K) Expert Linears  from SPE? I was initially leaning towards the 1.3K-FA without the ATU. The more I thought about it, the more I wanted to go with an ATU. The price difference to get less than 1db in going from 1300 watts to 1500 was also a bit of a concern. However, I?ve never pushed my 3x8874s to more than 1200 and only on the low bands. I have a KPA500 with the KAT500 and it?s great. However, in a 160 pileup a bit more power would help. Changing bands quickly is awesome. That has me leaning towards the KPA1500. If anyone would like to share their thoughts, it would be greatly appreciated.

Also, I?m wondering if anyone has run their KPA500 and a KPA1500 off of the same K3? If so, how did you set it up?

Tnx es 73,

At the same time? [:-)? Actually, I suppose one could drive 2 KPA500's

Based on my experience with the KPA1500, you shouldn't expect to run a 
solid state amplifier too close to it's rated output unless the SWR is 
pretty low, like better than 1.2:1. An ATU may or may not be able to 
keep the SWR that low. Otherwise, at a higher SWR, the amplifier output 
will sometimes drop to perhaps 2/3 the rated output, or the amplifier 
will fault due to high current or drive power. I expect the Expert 2K 
would have enough margin to put out 1.5 kW at higher SWR, but that extra 
margin comes at a cost.

Actually, Elecraft should do that as an experiment.  They could either make or specify appropriate combiners/splitters to use on front and back and solve other problems that might crop up.  Surely they have lots of KPA500s sitting around.  Lots and lots. :-)

73, phil, K7PEH

P.S.  My off-hand comment can be blamed on the fact that I am sitting here snowed in until maybe March with nothing else to do.  I live in Kirkland Washington and there is 16 inches of snow on the ground (all time record) -- we normally have rain with merely wet streets so this is a new thing.

I have had the SPE 1.3k and now have the KPA1500. I drive them with a Flex 6600 and Anan 7000dle. 

The issue I had with the SPE 1.3k was once you start pushing it past 1 KW out the TX IMD starts to really get bad. This is due to the single LDMOS RF device being pushed towards its limit. The other issue I had with the SPE is heat dissipation on long SSB transmissions and digital transmissions. The fans would ramp up very quickly and were more noise than I wanted in the shack. As it heated up the power would drop off high to mid power.

The KPA1500 fans will still spin up faster with long transmissions or during digital operation but the power supply unit can be located under the desk, reducing some of the noise. Also the fan profile is such that they can be set to have the PA deck turn off or be set to one of five levels. If the temp increases past a certain point the fans will increase.

The other thing is the tuner on the KPA1500 is MUCH better than the SPE 1.3k. The SPE amp would not tune my G5RV on 80. The KPA1500 tunes it, although on one end of the band at reduced power (1200 watts). So the tuning range on the KPA1500 is superior.

I'm happy I spent the additional money on the KPA1500.

If you cherish silent, perfect CW QSK, then you need the KPA1500. SPE uses

I'd be interested in the IMD figures with this configuration.

Are the amps being driven hard wire / parallel at the inputs or from a 
power divider??? And how are the outputs summed?? Power divider??? How 
much loss is in the output summing network??? And is it broadband 160M - 
6M?

Another thought is to use a broadband balun and drive the amps in 
push-pull.?? Both input and output likewise.?? Hummmm...... I'll have to 
think about that.

All interesting questions.

Obtain input splitter and output combiner units from W6PQL.  Install these into boxes with connectors.



Connect the AUX ports on each amplifier in parallel using a HD15 Y cable.



If you want a full 1000 watts out on the higher bands, modify the KPA500s to remove the input attenuator.  This allows a single K3 to drive both amps to full output even on 10 meters.



Connect inputs to the splitter, outputs to the combiner using (obviously) equal length coax to main phase relationship.



Some assembly required but not rocket science.

I don?t have the facilities to measure IMD, but in 3 years I?ve never had an on-air complaint.  I also don?t have lab grade power measurement available, but there appears to be little loss in the combiner based on basic external wattmeter measurements.  I don?t operate 6 meters, but 160 ? 10 is no problem.



The W6PQL splitter/combiner are the units he makes for his two pallet amplifier kit.  So they are being used well below the designed power level.

"Actually, I suppose one could drive 2 KPA500's from one K3 and sum the output for a virtual KPA1000."

If you dig a little into the design of the KPA500 you will find it has provisions to support 2 PA modules.  I have no doubt that Elecraft experimented with a dual  PA configuration before changing to designing the KPA1500.

Anyone willing to share some details?

I've employed a small solar power system to supply my ham shack which

TV.  This began as a basic test bed to understand Solar Power, so i know i

I'd like to hear  of your trials, errors, and decided solutions for best

inverter so i can merge my ATT u-Verse gateway/wi-fi and associated devices. 
Also, when running CW on the K3 i occasionally encounter LOW BATTERY error,
requiring a few seconds of UP-Key to allow the batteries to recover.  I'd
like to discuss that symptom relative to my sizing considerations in the
Solar Power system.  On paper it appears sufficient.  Sometimes i

Mike,
     One of my ham friends has his next door neighbor using solar power. It
is causing a lot of RFI across most of HF. I suggest that you require your
supplier supplier to use RF quiet solutions.

Just my 2 pence though nobody asked for 
it, Elecraft is one of very few companies 
that define the word integrity, another 
such company is HI-Z antennas who also 
goes overboard to be helpful in whatsoever 
is needed. I know there are other 
deserving companies out there, but these 
two are to me in the ham world, at the 
pinnacle of integrity and respecting the 
customer's needs and point of view.

All electronic pieces of equipment are 
subject to breakdown, especially those 
dealing with RF. Elecraft gets the repair 
work done correctly, as fast as is 
possible and they are more than reasonable 
in their billing. Add that their tech help 
is stellar and you have a quality 
operation. 

With quality and service such as this, 
I'll be happily using their products till 
the end of my days.

I'm just sayin'

Subject: [Elecraft] Elecraft business practices - more info
Message-ID: <1550093238076-0.post@n2.nabble.com>

I heard from Elecraft Sales and will attempt to communicate what I was told. 
Sales is using a new shopping cart platform which allows them limited time
to capture payment information. As a result, it seems that they are unable
to defer payment in the case of a backorder, so orders are charged
immediately (as was the case for the two orders I placed recently). 

They said that they are testing a new application which will allow deferring
payment until actual ship time. The target for this application to be
implemented is next month. In the mean time they said they will add a refund
offer to the notifications they send to customers when a backorder occurs.

I am generally satisfied with this explanation but would have liked to have
told in advance.

A US company called Genasun makes several models of MPPT charge 
controllers that are RF quiet. I use two in my shack, and W6GJB has two 
in his contesting trailer that we use for CQP, 7QP, and Field Day.? They 
make different models for lead-acid, lithium, and lithium-ferrous 
phosphate batteries, and with several different current and voltage 
ratings.

I have been using a solar system with my station for 5+ years. I 
use a charge controller from CirKits 
<http://www.cirkits.com/scc3/> for my lead-acid AGM batteries. I 
have about 135 AH of battery and about 10-15 A of "12V" panels. 
(Note that the capacity of lead-acid batteries is much less than 
what is advertised. Ditto for the current from solar panels. The 
LiFeSO4 batteries seem to deliver closer to their specification.)

I power the K3, P3, antenna switch and various other things from 
the solar system. My laptop and the SVGA screen for the P3 run 
off mains power. I am in the process of setting up a 10" 
HDMI/VGA monitor that will run on 12V at 700-800 mA from 
Adafruit as a second monitor for my computer. It may also work 
as a SVGA monitor for the P3, but hasn't been tried yet.

If the batteries are fully charged I can operate a weekend SSB 
contest, assuming normal sleep and contact with the family. 
Operating QRP will go for a long time.

The charge controller can handle up to 20A of charge current, 
with modifications for 40A and 60A. The fact that the 
modifications include changes to minimize RFI gives me a warm fuzzy.

I also use a boost regulator to give my K3 about 13.5 volts. 
Mine is a TGE N8XJK Boost Regulator, which mostly works. It is a 
"20A" unit and tends to overheat and pop its 30A breaker when 
running with low battery voltage in high demand modes like FT8. 
Also, all the chip numbers have been scratched off and there is 
no circuit schematic. I would look for a different boost 
regulator if I were buying again.

A big deal everywhere is voltage drop. If you have 0.01 ohms 
between the charge controller and the batteries, and they are 
charging at 10A, them you will get a 0.1 volt drop in that line. 
If the charge controller is sensing battery voltage at its end 
of that circuit it will be off by 0.1V. Since the float voltage 
for my AGM batteries is between 13.4 and 13.6 volts, small 
values of resistance can lengthen charge times. (The charge 
controller thinks the battery voltage is higher than it really 
is, and cuts charge current. With less voltage drop, it raises 
the charge current. etc. etc.)

I'm thinking of trying a modification to the CirKits charge 
controller to use a separate wire between the battery and the 
voltage sense circuit, but haven't gotten around to it yet.

Being in the payments industry, I can tell you that most of these policies
are driven by the card brands (Visa, MasterCard, etc.), certifying bodies
(PCI, EMVCo) as well as the payment gateways.  It is a very complicated
chain with many rules.

The shopping cart either does an immediate charge or what is called a
"pre-auth" where it holds the funds but does not transfer them yet.  If and
when they decide to actually charge the card, then a complete/post-auth is
issued.  The catch is that if a pre-auth is issued it will reverse
automatically if no complete/post-auth is issued, usually within 24 hours.
So the only practical choice is to charge the card.

The alternative is for the shopping cart to get a card token from the
gateway that it can store and retrieve for later payment.  It is verboten to
store clear text card numbers, in any media: computer, post it note, etc.
When the order is shipped, operations tells the shopping cart software to go
ahead and charge against the card token.  In this scenario it would be best
practice to the shopping cart software to also delete the token and
associated card data from the payment gateway, unless the cardholder
explicitly opted in to save card info.

This is not an Elecraft only issue.  Payments are very complicated and
challenging for many merchants.  Fundamental reasons are for risk reduction
(for all stakeholders) and security.

I heard from Elecraft Sales and will attempt to communicate what I was told.

Sales is using a new shopping cart platform which allows them limited time
to capture payment information. As a result, it seems that they are unable
to defer payment in the case of a backorder, so orders are charged
immediately (as was the case for the two orders I placed recently). 

They said that they are testing a new application which will allow deferring
payment until actual ship time. The target for this application to be
implemented is next month. In the mean time they said they will add a refund
offer to the notifications they send to customers when a backorder occurs.

I am generally satisfied with this explanation but would have liked to have
told in advance.

Again, I have been a loyal and satisfied Elecraft customer for many years
and am not attempting to in any way talk anyone out of doing business with
them. I was surprised when my credit card was charged twice before shipment
was projected to occur and now I have more knowledge.

Thanks,
Lou

I'd start by opening the box and check the input and output of the 
regulator, U4, being a LM7805.?? Should have ~12V on the input and 5V on 
the output.? If there is not 12V on the input then check both sides of 
the diode, D8, which is in series with the 12V input.? Also there is an 
inductor/choke L9 in series with the 12 volt line to the LM7805.

If the LM7805 does not have 5V on the output, either it has failed or 
there is a short which is pulling the 5V line to zero. Schematics are 
available and the rest depends on your trouble shooting skills.

Otherwise, obtain an RA from Elecraft Tech Support.

Jim,

If you don't have a schematic you should download one.  According to the
schematic there isn't any internal fuse.
The 12VDC is passed from the rear panel jack through a polarity protection
diode to a choke then to a voltage regulator, a LM7805.

To start, you need to open the case and check that there is 12V on the jack
*inside* the case.  Then check if there is 5V at the regulator output.

If there isn't 5V at the outout check the regulator input side for
approximately 12VDC and work back through the choke and diode until you
find the defective component.

If the LM7805 has 5V on the output then it is likely there is a logic
failure and you should contact Elecraft.

Gl!

Cliff,

Thanks for your insightful post. I was in the mail-order biz in the 80s, 
and we had to rely on weekly mailings of flagged credit card numbers. It 
was a PITA to look up every number taken over the phone and most of us 
at this place relied on 'gut' instincts based upon the behavior of the 
caller. Much safer now!

Eric,

Just to be correct, my K2's S/N is listed incorrectly. 
It appears the K2 was MUCH more popular than I ever thought it was:

"K05V               Jim      NM      K2        82255"

It should be 7225. Sorry if I mumbled!

The present KX3 Utility and PX3 Utility are 32-bit apps on Apple?s OSX platform.  Does anyone know if Elecraft plans to update these to 64-bit anytime soon?  With the release of the next version of OSX later this year, those applications will no longer work in their current guise.

Thanks for any insight?

Message-ID: <2393E2DA-FF38-49C0-A5D9-4C1FED4E6A5F@gmail.com>

To reduce the overall footprint of ?stuff? around here, I?ve purchased a Bodnar GPS to replace a Trimble Thunderbolt, open frame power supply, and status display for use with my K3.

Is there a recommended output level from the Bodnar for the K3?  it seems the lowest level should work ok, but just checking in case I don?t understand something .. which is probably more likely than not.

... and being in the service provider business, I can tell you that way 
too many shopping carts are set up on the assumption that the product 
will ship within 24 hours.

The typical developer has never read a merchant credit card agreement, 
and doesn't know that many of them state that you do not charge the card 
until the merchandise is actually shipped.

The developer doesn't seen a need for split transactions, since no one 
ever mentioned that they'd be taking orders for a very expensive product 
with an order backlog.

I'm ashamed of what my industry has become.

Grant,

I just bought one of those a few months ago. I don't have it in front of 
me, but as I remember, the default output from the Bodnar unit was 
exactly in range of what is required by the K3. I didn't have to change 
anything in the setup to get it working correctly with my K3.

I have one of these and set it to 8mA output for several years with no problem.  I chose it based on the following:

From the K3EXREF manual

Connect the external 10 MHz signal source to the rear panel REF. connector. The 10 MHz source
should have a signal level between +4 dBm and +16 dBm, nominal. For square wave sources, 2VDC to
3.3VDC peak is optimum. If the source is a 5V logic level, use a 50-ohm resistor in series with the
input. Caution: To avoid damage to the K3EXREF, do not exceed these levels.

From Bodnar?s website:

Both output signals are at 3.3V CMOS levels with 50 Ohms characteristic impedance. Their output drive levels can be adjusted.
Output power level (measured at 10MHz, fundamental power channel):

+13.3dBm, drive setting 32mA
+12.7dBm, drive setting 24mA
+11.4dBm, drive setting 16mA
+7.7dBm, drive setting 8mA

My computer does not have a 9 pin serial port. I have a 9 pin to USB

has a 9 pin serial port, to the computers USB.
The manual for the KIO2  says you can use a 24 pin to 9 pin adapter, but it
does not mention connecting to USB. Since the cable is so specialized for
the KIO2 to K2 can I connect it with the 9pin to USB prolific cable? I
don't want to short anything out etc...

Hi, Tom -

I don't have the specific DB9 to USB adapter that you have, but do this one:

https://www.startech.com/Cards-Adapters/Serial-Cards-Adapters/1-Port-USB-Serial-RS232-Adapter-Cable~ICUSB2321F

which I use with both the KIO2 as well as the DB9 port on the KPA100 and it
works great.

>From what I've read, the FTDI chipset, which the Startech product
implements, is the best choice in this application.

From experience I find the units from R T Systems are 100% reliable. Much more so than the office supplies, electronics stores, Walmart and such. Plus if you have questions, a phone call allows one to speak with a real person in the USA.

Be absolutely sure to use the cable as described in the K2?s KIO2 manual to connect the K2 to the USB adapter. Using a straight-through cable will cause damage to the K2.

Also a lot of people have issues with Prolific chipset USB cables, especially on Windows 10. The cables with FTDI chipset are much more reliable.

Be absolutely sure to use the cable as described in the K2?s KIO2 manual to connect the K2 to the USB adapter. Using a straight-through cable will cause damage to the K2.

Thanks for all the feedback. Yes, I built the cable that came with the it
and I am definitely going to use it put the 9 pin to USB on the end of it,
I know you  cannot any other 9 pin cable.
Also I will get a proper cable with a good chipset to take it to USB.

Tom,

Do NOT connect a standard serial cable or a USB to RS-232 adapter to the 
K2 (KIO2) AUX IO connector.  Note that it is labeled AUX IO and NOT 
RS-232.  It contains internal K2 signals for external Elecraft gear such 
as the KAT100, KRC2 or the XV series transverters.

Build the special K2 to PC cable if you have not done so already, and 
connect it to an RS-232 port on the computer.  If you do not have RS-232 
ports, then you will need a USB to RS-232 adapter.  Those with an FTDI 
chipset such as the Elecraft KUSB work best.  Those with a prolific 
chipset are problematic.

Don W3FPR

Message-ID: <1534363162.4199.1550250125761@wamui-koala.atl.sa.earthlink.net>

Good morning,

I have a HupRF PAT tap buffer amp board for my K2's IF. I installed an SMA connector on the heatsink panel
when I built the rig. 

Looking at the K2's block diagram, the IF is shown between the mixer and post-mixer pre-amp. On the schematic,
that appears to be between Z6, pin 2, and C159. My plan is tap the mixer-side of C159, then attach the ground 
braid to the ground side of R80. Is this the right way to do this?

I've searched this reflector, and the web, and I can't really find anything specific using "K2 IF out", etc. 

SDR kits' site (they sell G4HUP's kits since Dave passed away), and the HupRF site have no instructions for 
Elecraft rigs. There are links to installation instructions in the most popular Yaekencom radios, but not the K2, 
even though they are selling the K2 boards.

Thanks again. 73,

Jim KO5V

Jim,

The IF take-off point normally used for the K2 is at J12 pin 1 which is 
after the Post-Mixer amplifier.  That point provides a signal that is 
about equal in strength to the antenna input affords isolation for BFO 
leakthrough.

For everyone's information, DX Engineering is selling the Clifton Labs 
buffer amplifier (but not the specific K2 version that Jack Smith (SK) 
also sold.

I found that any wired keyboard I used would suffer from the same problem,
usually a runaway transmit condition, where new characters got jam-crammed
into the keyboard buffer due to stray RF. This kept the KX3/PX3
transmitting until cancelled manually.

Bluetooth keyboards don't work because there's no way to see a pairing
code, but dedicated 2.5ghz dongle-type wireless keyboard works fine. I got
this inexpensive one from Amazon, and it has zero problems, probably
because it doesn't have a wire acting as an antenna to haul in stray RF and
jam it into the keyboard buffer.

https://www.amazon.com/gp/product/B0787G1YFG/

I wish this keyboard would work with my HobbyPCB IQ32 as well as the PX3,
but for some reason, it doesn't. Only an ancient Compaq keyboard with the
PS/2 DIN plug works properly on that machine...and I was hoping I could use
a more compact keyboard for it. So far, the only keyboard that works weighs
four times what the radio does. :/ The PX3/KX3 is far more reasonable and
behaves itself appropriately.

Run one instance of KPA1500 Remote on a computer that's always running at
the radio site. Tell it the COM port for the KPA1500 and Start Hosting
Remote. Specify the Server Setup parameters; the critical one is TCP Port
which must also be set up in your Internet router for *port forwarding*.
Each router model and firmware release may have a different way of setting
this up; sorry.

At the control site, run another instance of KPA1500 Remote, typically on
your logging computer, and tell it to Connect. Specify matching parameters
including that Internet port number. Port forwarding isn't required on the
control side. If you have it all specified correctly, the control site
instance will connect to the radio site instance and work beautifully. At
least, it does for me. Great program!

It works great for me, Burl. Please see my reply just moments ago to
another frustrated KPA1500 Remote user. The key might be port forwarding
which varies with router model and version and can be tricky. I connect the
radio site KPA1500 Remote instance using a USB-to-Serial adapter to the DB9
on the amp rather than the LAN interface. I don't need Wake on LAN in this
setup. When I launch the radio site instance of KPA1500 Remote and do Start
Hosting Remote, it always turns the amp on. If I'm just setting up the
server computer and don't want the amp right away, I just click the POWER
button to turn it off. When I start the control site instance and do
Connect, it connects to the radio site instance and does *not* power on the
amp until I click POWER. I live happily with this little inconsistency.

Yes, one can use a remote desktop facility like Teamviewer to control the
radio site instance of KPA1500 Remote. I did this using Chrome Remote
Desktop with KPA1500 Utility before KPA1500 Remote became available. But
it's not optimal because you have to size and position your remote desktop
window with the KPA1500 Remote window properly positioned and sized inside
that. It's awkward. Keep working on KPA1500 Remote and get it working in
its intended client/server configuration. It's "easy once you have it
working" and well worth the effort.

Do you know what has to be done (extra circuitry etc) to get the DXE Clifton Lab amp to work with a K2 and essentially mirror the functionality of Jack Smith?s one?

Do you mean driving both a KPA1500 AND a KPA500 at the same time?! I don't
know where that would be legal, practical, or desirable. But there's lots
of stuff I don't know...

If you mean driving one's choice of KPA1500 OR KPA500, read on:

Before KPA1500 became available, I had an Alpha 87A on K3 Rig 1 and a
KPA500 on K3 Rig 2 for local SO2R operation. When I left that house and
went to my valley QTH, I took Rig 2 with me and used it as a remote control
head for Rig 1. The remote control app for the Alpha was ancient,
unsupported, and had a pixel-level user interface which made it tiny and
hard to read on a modern computer monitor. I also felt queasy about
operating the Alpha remotely without the ability to hear its gears groaning
and see its real front panel. So I rigged up the two amps to be selectable
remotely and used the KPA500 most of the time via KPA500 Remote and KAT500
Remote. If I needed to bust a big pileup, I would occasionally "wave my
magic wand" and use the Alpha.  Once I replaced the Alpha with the KPA1500,
this was no longer necessary but I still have the capability.

To provide remote amplifier selection, I connected the Alpha (now KPA1500)
to ANT1 on the Rig 1 K3 and the KPA500 to ANT2. I connected both band
decoders and amplifiers in parallel to the K3 DB15 ACC connector. I would
selectively power on one and only one band decoder using a remote
controlled relay board from Velleman. Thus, the active decoder would drive
a Six Pak antenna switch to connect the correct antenna to the desired
amplifier and the ANT switch on the K3 would complete the correct RF path.
PTT and band selection for the amps came through the DB15. The jungle of
15-pin Y connectors was pretty ugly - now I have an N6TV Y-Box which is
cleaner. This setup worked most of the time, although I did occasionally
encounter balky decoder operation, I think due to marginal fanout or lack
of pull-ups on the ACC band data signals from one of the K3 radios. (I
didn't always have the same K3 set up as Rig 1 or Rig 2/Control Head.)

Since I installed the KPA1500, I haven't used this complex setup. KPA1500
and KPA500 are nearly identical through their respective KPAxxx Remote
control applications and, in fact, KPA1500 Remote is more convenient
because it bundles the ATU controls instead of requiring a separate KAT500
Remote application. So I just use the KPA1500. It was a fun exercise in
system integration, though!  ;-)

Since I have no had my hands on a DXE buffer amplifier, I have to guess.
Jack had a bandpass filter designed for the K2 at the output that peaked 
the response at 4915 kHz.
I have the Z10000B-K2 buffer instructions on my computer.? If DXE is 
using the same board layout, then it should be easy for anyone to add 
the filter from the instructions.

If you want a copy, send me an email off-reflector and I will send a 
copy to you.

Message-ID: <031301d4c568$11cb6500$35622f00$@ameritech.net>

My K3 (modified to K3s) is giving me a problem for the first time in ten
years.  I first noticed it driving the KPA1500 erratically. It would go from
a few hundred watts to excessive power and faulted out.  In order to narrow
down the problem, I disconnected the K3 from the KPA1500 and put a dummy
load on the K3.  Under 12 watts, the K3 worked well.  Over 12 watts, the K3
showed high SWR increasing as the power went up.  The cooling fans turned on
indicating something was getting warm.  I put the dummy load on Antenna 1
and Antenna 2, selected them and got the same results.  I then did a
Transmitter Gain Calibration which failed the 50 watt, high power
calibration but passed the 5 watt calibration.  

 

I called Elecraft Technical Support but they are short handed due to
numerous people being out with the flu.  I wonder if anybody has any ideas.
I'm thinking it's a sticking relay or a PIN diode possibly after the finals.

Well, I got it to work finally, tnx to all and Paul, K9NU ......
Now the question is, is it possible to control the amp remotely WITHOUT having a dedicated PC running ?
VPN, different port forwarding ..... some other configuration ? 

Or is it just not possible the way the software is written and requires a different control program ?
Thanks to all for the assistance .....

Hi Rick

Thanks for the info. I have been doing K3 remote for 3 years and everything is working flawlessly.  I rent state IPv4 addresses and familiar with port forwarding.   I can turn the amp On with macros using the K3, but the remote Elecraft software KPA 1500 does not respond  / work.


Still hoping for a miracle ?.   Burl,   AJ9Q

The key might be port forwarding which varies with router model and version and can be tricky. I connect the radio site KPA1500 Remote instance using a USB-to-Serial adapter to the DB9 on the amp rather than the LAN interface. I don't need Wake on LAN in this setup. When I launch the radio site instance of KPA1500 Remote and do Start Hosting Remote, it always turns the amp on. If I'm just setting up the server computer and don't want the amp right away, I just click the POWER button to turn it off. When I start the control site instance and do Connect, it connects to the radio site instance and does not power on the amp until I click POWER. I live happily with this little inconsistency.

I did this using Chrome Remote Desktop with KPA1500 Utility before KPA1500 Remote became available. But it's not optimal because you have to size and position your remote desktop window with the KPA1500 Remote window properly positioned and sized inside that. It's awkward. Keep working on KPA1500 Remote and get it working in its intended client/server configuration. It's "easy once you have it working" and well worth the effort.

that I cut and pasted from a posting in October 2015.? I think this is a 
small subset of keyboards that are compatible with the PX3 and P3 with 
SVGA option.? My understanding is that pretty much any keyboard that is 
not Bluetooth or "multimedia" should work.

Most Logitech keyboards work well with the P3.

Several wireless Logitech keyboards have a very interesting feature - they can connect to several computers or devices, switching between them by simply tapping a key on the keyboard. As an example, I use a K780 with a Logitech Unifying receiver plugged into my P3. A second Unifying receiver is plugged into my Mac mini. By tapping the ?F1? key it talks to the P3, then I tap the ?F2? key to work with the Mac. If you have a third device (another computer or even a second P3) it can connect to that also. It can use Bluetooth or Unifying for any of the devices, although you need to use the small Unifying receiver with a P3. There are several keyboards that support this feature at various prices, including the K780, the Craft, the K600 and a few more. It?s pretty neat, eliminating the need for several keyboards at once. If you look at Logitech keyboards, steer clear of the Bluetooth-only keyboards for this use. The P3 does not support the Bluetooth stack, so plugging a Bluetooth dongle into the back of the P3 is pretty much a waste of time. It works very well with the Logitech Unifying USB dongles and keyboards, though.

And, for the record, I work for Logitech these days. What that really means is that I have tried Logitech keyboards. There may be wireless keyboards made by other companies that work in this situation also; I just haven?t tried them.

Hi Bob,

On a related subject, but not quite what you asked about, if you are 
just looking for a way to fire off macros at the K3, and have the SVGA 
for the P3, see:

https://www.nk7z.net/adding-external-keypad-k3/

This is a way to use a 64 key Genovation keypad to fire off complex 
macros to the K3/P3, using a single keypress, from a dedicated pad, as 
opposed to having to type in macros, or triggers to the K3/P3 radio 
complex via a keyboard.

An example of what can be done would be the "Offset +" macro-- I press a 
single button on the Genovation keypad, and the Radio drops into split, 
the P3 shifts the CW signal to the left side of the display, while 
setting the bandwidth for the P3 to 6 KHz., to show the top part of the 
pile up, and then sets the K3 bandwidth to whatever I have set in the 
macro, all with a single button press.

I currently have 32 macros programmed up, some for power level setting, 
switching VFOs, triggering the K3 memories in CW or Voice, setting K3 
bandwidths, contest exchanges, IDs, etc.

There is a spread sheet of macros you can download for use within the 
Genovation setup at that URL as well.  I seldom even touch the K3 now, 
but to tune, or turn it on, or off.  Most of my K3/P3 operations comes 
from the Genovation keypad.

Thanks for the replies on my posting about my KAT500 not powering up.It turned out to be a bad coaxial power connector! My KAT500 is back working like before.Thanks for the ideas to get my tuner working and it turned out to be a coaxial power connector, stupid me!Jim Douglas? K2ZF?

The 48 key Genovation is WONDERFUL!!!? It allows me to do most 
everything with the touch of a button or two - from memories, to 
filters, to tuning, and more. The only limit is your imagination for 
building macros. I never have to reach across the desk to hands-on the 
K3 except to turn it on and off. Need more desk edge control? Get a 
KPod. BTW I use an old wired keyboard for the P3.

Message-ID: <013901d4c603$e97e3130$bc7a9390$@w2irt.net>

I was operating in the ARRL-CW contest this morning and on 20m, with a 1.2:1
SWR on the Yagi, all of a sudden I saw my power drop to about 450-500W with
about 40W in. Worked a few stations but not as easily as when I turned
everything on this morning. Switched over to phone and made a few contacts.
Audio is fine barefoot with 100W out of the K3s-which suffered blown finals
itself during CQWW SSB last fall, but with the amp in I got reports that my
audio was badly distorted. 

Before I send it in, is there anything I should look at or any diagnostics I
can easily perform? For the cost of this, I'd have thought protection would
have kicked in to prevent anything untoward from happening. I'm in complete
disbelief, to be honest.

I think a two-tone test is the best evaluation tool..? The generator is built 
into the K3 if you have another receiver that you can use to listen to the amp 
output.? I use an SDR-IQ which is a very nice tool for this but any other SDR 
would do.

Sorry for your pain.

I talked to Peter on the phone. He has no bias current when amp is transmitting with no power applied (key on SSB without talking. He is reading 54 volts and has tried power cycling amp from power supply switch and reseated all cables. Definitely BAD distortion on SSB (we are close enough to hear each other). Looks like one RF device let loose and it is dragging down the bias voltage. That is my guess.

It sounds like one of the output devices have failed. Half power out 
is usually the indicator. A number here have reported this happening. 
It would be nice to know why this problem is occurring and if 
Elecraft are working on a fix.

Exact same thing happened to my K3s in October, now my KPA-1500. Yeah, So
done here. Once repaired and confirmed working it will be up for sale. Going
back to a tube amp after this.

It's been said there are no coincidences. Have you checked your coaxes /
connectors? I agree that protection built in should not allow radios to
blow finals, but this sounds like too much of a coincidence with two
different radios blowing to not be an external intermittent connection. Try
wiggling all the cables with low power. Unfortunately, sometimes a problem
will only show up as arcing at high power. Is there another HAM near you
with a powerful amp and antenna close to yours?

Best of luck,

His radio blew one final while driving the KPA1500 in the fall. 

Now his amp blew one LDMOS. 

I?ve been to Peter?s house and used a TDR to check all of his antennas, cabling, and switching. Cable connectors replaced last year. 

I agree it is good idea to check everything again. Looking at the amp fault log today did not show signs of anything arcing

I agree that protection built in should not allow radios to blow finals, but this sounds like too much of a coincidence with two different radios blowing to not be an external intermittent connection. Try wiggling all the cables with low power. Unfortunately, sometimes a problem will only show up as arcing at high power. Is there another HAM near you with a powerful amp and antenna close to yours?

Unfortunately, you're wrong.? My K3S has failed multiple times.? Fortunately, my 
KPA500 has not.? I'm not in the market for a KPA1500.

Sorry to hear this happen Peter, especially during a contes. LDMOS devices
are suppose to be pretty tough and the KPA1500 is not pushing their limits.
There are videos of a different LDMOS showing it to be indestructible:
https://www.youtube.com/watch?v=8ziYqjMQGEQ  Is the KPA1500 cooling and heat
sink adequate?  Personally if I owned this amp I would leave the fan on at a
tolerable speed 100% of the time.  Did you use the amp during the RTTY
contest last weekend?

Do not trust PL-259 connectors installed only "finger tight". Today many 
of those PL-259 connectors "look good" but are really poor quality 
connectors.??? ALWAYS snug the PL-259's with a pair of 4" channel lock 
pliers.?? You'd be amazed how many strange issues will go away.

Not saying this is or was the cause of failure, but I've seen it and 
experienced it too many times.

Also, for other reasons, I run the ALC from my KPA500 to my K3S.?? 
Again, another issue of concern resolved.

Hi Peter,

I'm sorry to hear about this failure and deeply apologize for the problem. 

I'll follow up with another email to you to diagnose what actually happened. 

In any case we'll deal with it quickly and get your amp repaired asap.

This discussion has risen its nasty head earlier.? Wes and I exchanged 
several private e-mails on the topic.? Here is what I've learned:

My purchased new from the factory my K3S -100 in August of 2015. With it 
I drove my AL-80B with 60 to 80 watts for some two years.?? Absolute no 
issues of concern.??? In April of 2018 I purchased a new KPA500 and put 
it in place of the AL-80B.?? I drove the KPA500 with my K3S at 15 watts 
for some 2 weeks.? Then reports of "fuzzy audio" surfaced.? The 2 tone 
test revealed excessive IMD.? I contacted Tech Support and they arranged 
to send me a LPA3 and a KPA3A.?? These were installed and all was well 
for about one week.? Then again the reports of "fuzzy audio".? I 
contacted Tech Support again and they said "send it in".?? The service 
report indicated they replaced the KPA3A with a rev E which is reported 
to be more stable.? An interesting comment on the Elecraft Service 
report; "Due to failure of the stable rev E amp, this indicates 
something in the shack.?? Possible kickback from and amplifier.?? It is 
likely to happen again if the root cause is not found. ........"??? 
UGH...folks, the amp is a KPA500!???? >> HOUSTON - DO WE HAVE A PROBLEM?>>

In the discussions via e-mail and here on the reflector which followed, 
I learned of others which experienced the same type issues.? I asked 
"what's the solution".?? Interestingly the answer came back [I don't 
recall from whom}? "stay away from 15 watts". Since then I have driven 
my KPA500 with 20 watts .....PLUS? I have connected and engaged the ALC 
from the KPA500 to my K3S.? This is a menu item in the K3S.? Now some 
may not like the ALC connection and activation.

My thinking is that IF there are any spikes originated with the rise of 
the CW signal or voice signal this may overdrive the amp.?? With my P3 I 
see this A LOT on SSB signals on the bands which exhibit initial ALC 
overshoot.? This is both on CW and SSB. ?? Makes me wonder what does the 
input impedance of the KPA500 does when hit with a millisecond or so of 
excessive drive? ? Not long enough to activate the attenuator or throw a 
fault signal. I do know that tube amps reflect to their input the 
effective tuning of the output. ? Could this be an issue with solid 
state amps where the input impedance goes to zero thus placing in effect 
short on the driving transceiver? ? Mind you not long enough to throw a 
fault signal but........what does it do to the driving stage? ? ? I've 
not measured it and am not exactly sure how to accomplish this.? It may 
not be the issue at all.?? Perhaps some of you more technical gurus can 
expound further on the topic.

I do know factually since the change to the KPA3A? rev E, and I 
activated the ALC between the KPA500 and my K3S the issue has not reared 
its ugly head. ? Lets hope it doesn't.

All in all, I am VERY pleased with Elecraft Tech support and extremely 
pleased with my K3S, P3, KPA500 and KAT500.? A winning combination.?? 
But I'm still walking on eggs? and hoping none break.

I agree with you re PL-259s. I follow best practices in this regard. Quarter-turn with channel-locks after finger tight, Amphenol 83-1SP, assembled correctly, with cables swept by a TDR.

Do not trust PL-259 connectors installed only "finger tight". Today many of those PL-259 connectors "look good" but are really poor quality connectors.    ALWAYS snug the PL-259's with a pair of 4" channel lock pliers.   You'd be amazed how many strange issues will go away.

Not saying this is or was the cause of failure, but I've seen it and experienced it too many times.

Also, for other reasons, I run the ALC from my KPA500 to my K3S. Again, another issue of concern resolved.

I agree that protection built in should not allow radios to blow finals, but this sounds like too much of a coincidence with two different radios blowing to not be an external intermittent connection. Try wiggling all the cables with low power. Unfortunately, sometimes a problem will only show up as arcing at high power. Is there another HAM near you with a powerful amp and antenna close to yours?

If you live in North America, the ONLY good PL-259 connector is one that 
labeled Amphenol 83-1SP.? Most others are JUNK.? I'm told there are some 
other decent brands sold in EU.

RIGHT. And always be VERY careful about how you solder them, especially 
the shield.

Who uses PL-259s?  They suck.  I ordered my K3S with Ns and really should have specified DINs.  But, that is a retrofit project for another day.

Bob and all,

I think this problem is not so much with the amplifier, but the K3/K3S.
Consider that the switchover from the low power amplifier to the KPA3 is 
in the 12 to 15 watt range.  That is where the LPA is generating about 
all the power it can produce.  Above that range, the KPA3 kicks in and 
everything is "loafing along".

Oh yes, aside from that, some amplifiers do fail for various reasons - 
and I think we are mixing failures of the K3/K3S with amplifier failures 
in this thread.

73,
Don W3FPR

I don't contest in RTTY (I don't use that mode other than for Dxpeditions)
and rarely even do FT8. I mostly operate CW and a bit of SSB and that's it. 

I have no idea why it would fail. I did have some issues in the past with
antennas going stupid on me or the HF-Auto tuner failing to match when it
was supposed to, but those always hard-faulted instantly. I never attempted
to push RF through more than about a 2:1 without a tuner, and for CW, all my
antennas are resonant on the bottom of all the bands. That it happened on 20
where I'm about 1.2:1 is very strange.

Sorry to hear this happen Peter, especially during a contes. LDMOS devices
are suppose to be pretty tough and the KPA1500 is not pushing their limits.
There are videos of a different LDMOS showing it to be indestructible:
https://www.youtube.com/watch?v=8ziYqjMQGEQ  Is the KPA1500 cooling and heat
sink adequate?  Personally if I owned this amp I would leave the fan on at a
tolerable speed 100% of the time.  Did you use the amp during the RTTY
contest last weekend?

Viggo,

How do you propose to connect the SDR IQ to the KX3?
The KX3 does not have an IF output - in fact the KX3 IF is either at 
baseband or 8kHz if you turn on the 8kHz shift in the menu.

The KX3 DOES have the RX I/Q output which you can connect to a computer 
soundcard or the KX3 for a panadapter display.

Yes, the SDR IQ works fine with the K3 which has an IF output at 8.215MHz.

Guys

the problem here is not who use PL259 or what coaxial is using. I think
Peter and most of us, and mostly if you do contests, is not that, we are
using good coax and connectors over the years and no problem with other
radios or amplifiers, thats what Peter said.

If you are in a contest, you prepear your station to not fail. Robust
radios and amplifiers, not only pretty ones

Hopefully guys in USA will have this problem solved *easily*

But what about if you dont live in USA?  I didnt buy Expert 1.3K amplifier
because many owners told me about it?s fail. Is very expensive and dificult
to deal with customs to take it to USA and back to Uruguay to repair it.

So, KPA1500 is a robust amplifier?  Of course always will be a problem, but
is 1% or 25% of the cases?

And I dont want parts sent by Elecraft to fix it, I want an amp that not
fail

Message-ID: <001C6195-A361-434F-8C12-B7BF13B053D5@elecraft.com>

As time permits, we're trying to better characterize the RF noise that plagues stations at various locations. 

So far, data collected during this informal survey has taken the form of verbal descriptions. Scope traces or digitized samples would be much more helpful, since they'd show the actual waveforms. We could then look at how to better suppress the noise profiles, pulse widths, and rep rates encountered by stations surrounded by modern appliances, vehicles, peripherals, lighting, etc. Many of these didn't exist decades ago when the first noise blankers were designed.

On a K3 or K3S, the best place to capture noise signals would be at the output of the first MC1350 in the KNB3's amplifier chain. In the presence of strong noise, the signal at this point is likely to produce a visible scope trace, or a good sample using an RF digitizer. The latter would have to do a good job at the IF, 8.215 MHz.

On a KX3, the RX IQ outputs should work, assuming the noise signal is quite strong. As the RX IQ signal occurs at base band, a much lower-bandwidth scope or an audio-class A-to-D converter would suffice. 

Spectral data would also be of use in both cases.

I don't have any specific recommendations for equipment or software. But if you have the means in hand, as well as a noise problem worth capturing, feel free to contact me directly. Please include photos or screen captures as well as details on what remediation techniques work -- and don't.

FWIW, I use NO-OX-ID contact grease on my PL259 connectors. This allows 
very tight snugging by hand, no need of wrenching.

During lightning season I frequently connect/disconnect my rig and tuner 
cables. The fine film of lube on the connector threads makes a big 
difference. Without it? A real PITA, not to mention wear and tear on the 
the SO-239's.

I agree that protection built in should not allow radios to blow finals, but this sounds like too much of a coincidence with two different radios blowing to not be an external intermittent connection. Try wiggling all the cables with low power. Unfortunately, sometimes a problem will only show up as arcing at high power. Is there another HAM near you with a powerful amp and antenna close to yours?

Amphenol 83-1SP connectors are great however I have a number of Andrew
44ASP, L44P and L45P connectors in my system and I also consider to be very
high quality UHF connectors.

Jim Brown jim at audiosystemsgroup.com 

If you live in North America, the ONLY good PL-259 connector is one that 
labeled Amphenol 83-1SP.  Most others are JUNK.  I'm told there are some 
other decent brands sold in EU.

I never wrench. I just wiggle the connector as I tighten it and it tightens down into the v grooves tightly. Almost have to use a pliers to unscrew it.

FWIW, I use NO-OX-ID contact grease on my PL259 connectors. This allows
very tight snugging by hand, no need of wrenching.

During lightning season I frequently connect/disconnect my rig and tuner
cables. The fine film of lube on the connector threads makes a big
difference. Without it? A real PITA, not to mention wear and tear on the
the SO-239's.

Drew and all,

I have changed the subject line to something more akin to the current 
discussion.

Have you considered adding a coax switch?  Turning to switch to an open 
position (or better yet to a dummy load) when the radio is not in use 
will provide protection and is a lot easier than removing the connectors.

73,
Don W3FPR

Hello Elecrafters.,

Have some of you connected an SDR IQ to the KX3,, ( use as an Panadapter
with Spectravue) ?

Work very well with the K3........

Sorry to hear this happen Peter, especially during a contes. LDMOS devices
are suppose to be pretty tough and the KPA1500 is not pushing their limits.
There are videos of a different LDMOS showing it to be indestructible:
https://www.youtube.com/watch?v=8ziYqjMQGEQ  Is the KPA1500 cooling and heat
sink adequate?  Personally if I owned this amp I would leave the fan on at a
tolerable speed 100% of the time.  Did you use the amp during the RTTY
contest last weekend?

Do not trust PL-259 connectors installed only "finger tight". Today many 
of those PL-259 connectors "look good" but are really poor quality 
connectors.??? ALWAYS snug the PL-259's with a pair of 4" channel lock 
pliers.?? You'd be amazed how many strange issues will go away.

Not saying this is or was the cause of failure, but I've seen it and 
experienced it too many times.

Also, for other reasons, I run the ALC from my KPA500 to my K3S.?? 
Again, another issue of concern resolved.

Hi Peter,

I'm sorry to hear about this failure and deeply apologize for the problem. 

I'll follow up with another email to you to diagnose what actually happened.


In any case we'll deal with it quickly and get your amp repaired asap.

This discussion has risen its nasty head earlier.? Wes and I exchanged 
several private e-mails on the topic.? Here is what I've learned:

My purchased new from the factory my K3S -100 in August of 2015. With it 
I drove my AL-80B with 60 to 80 watts for some two years.?? Absolute no 
issues of concern.??? In April of 2018 I purchased a new KPA500 and put 
it in place of the AL-80B.?? I drove the KPA500 with my K3S at 15 watts 
for some 2 weeks.? Then reports of "fuzzy audio" surfaced.? The 2 tone 
test revealed excessive IMD.? I contacted Tech Support and they arranged 
to send me a LPA3 and a KPA3A.?? These were installed and all was well 
for about one week.? Then again the reports of "fuzzy audio".? I 
contacted Tech Support again and they said "send it in".?? The service 
report indicated they replaced the KPA3A with a rev E which is reported 
to be more stable.? An interesting comment on the Elecraft Service 
report; "Due to failure of the stable rev E amp, this indicates 
something in the shack.?? Possible kickback from and amplifier.?? It is 
likely to happen again if the root cause is not found. ........"??? 
UGH...folks, the amp is a KPA500!???? >> HOUSTON - DO WE HAVE A PROBLEM?>>

In the discussions via e-mail and here on the reflector which followed, 
I learned of others which experienced the same type issues.? I asked 
"what's the solution".?? Interestingly the answer came back [I don't 
recall from whom}? "stay away from 15 watts". Since then I have driven 
my KPA500 with 20 watts .....PLUS? I have connected and engaged the ALC 
from the KPA500 to my K3S.? This is a menu item in the K3S.? Now some 
may not like the ALC connection and activation.

My thinking is that IF there are any spikes originated with the rise of 
the CW signal or voice signal this may overdrive the amp.?? With my P3 I 
see this A LOT on SSB signals on the bands which exhibit initial ALC 
overshoot.? This is both on CW and SSB. ?? Makes me wonder what does the 
input impedance of the KPA500 does when hit with a millisecond or so of 
excessive drive? ? Not long enough to activate the attenuator or throw a 
fault signal. I do know that tube amps reflect to their input the 
effective tuning of the output. ? Could this be an issue with solid 
state amps where the input impedance goes to zero thus placing in effect 
short on the driving transceiver? ? Mind you not long enough to throw a 
fault signal but........what does it do to the driving stage? ? ? I've 
not measured it and am not exactly sure how to accomplish this.? It may 
not be the issue at all.?? Perhaps some of you more technical gurus can 
expound further on the topic.

I do know factually since the change to the KPA3A? rev E, and I 
activated the ALC between the KPA500 and my K3S the issue has not reared 
its ugly head. ? Lets hope it doesn't.

All in all, I am VERY pleased with Elecraft Tech support and extremely 
pleased with my K3S, P3, KPA500 and KAT500.? A winning combination.??

I agree with you re PL-259s. I follow best practices in this regard.
Quarter-turn with channel-locks after finger tight, Amphenol 83-1SP,
assembled correctly, with cables swept by a TDR.

Do not trust PL-259 connectors installed only "finger tight". Today many of
those PL-259 connectors "look good" but are really poor quality connectors.
ALWAYS snug the PL-259's with a pair of 4" channel lock pliers.   You'd be
amazed how many strange issues will go away.

Not saying this is or was the cause of failure, but I've seen it and
experienced it too many times.

Also, for other reasons, I run the ALC from my KPA500 to my K3S. Again,
another issue of concern resolved.

If you live in North America, the ONLY good PL-259 connector is one that 
labeled Amphenol 83-1SP.? Most others are JUNK.? I'm told there are some 
other decent brands sold in EU.

RIGHT. And always be VERY careful about how you solder them, especially 
the shield.

Who uses PL-259s?  They suck.  I ordered my K3S with Ns and really should
have specified DINs.  But, that is a retrofit project for another day.

Bob and all,

I think this problem is not so much with the amplifier, but the K3/K3S.
Consider that the switchover from the low power amplifier to the KPA3 is 
in the 12 to 15 watt range.  That is where the LPA is generating about 
all the power it can produce.  Above that range, the KPA3 kicks in and 
everything is "loafing along".

Oh yes, aside from that, some amplifiers do fail for various reasons - 
and I think we are mixing failures of the K3/K3S with amplifier failures 
in this thread.

73,
Don W3FPR

I don't contest in RTTY (I don't use that mode other than for Dxpeditions)
and rarely even do FT8. I mostly operate CW and a bit of SSB and that's it. 

I have no idea why it would fail. I did have some issues in the past with
antennas going stupid on me or the HF-Auto tuner failing to match when it
was supposed to, but those always hard-faulted instantly. I never attempted
to push RF through more than about a 2:1 without a tuner, and for CW, all my
antennas are resonant on the bottom of all the bands. That it happened on 20
where I'm about 1.2:1 is very strange.

Subject: [Elecraft] KPA-1500 failed!

Sorry to hear this happen Peter, especially during a contes. LDMOS devices
are suppose to be pretty tough and the KPA1500 is not pushing their limits.
There are videos of a different LDMOS showing it to be indestructible:
https://www.youtube.com/watch?v=8ziYqjMQGEQ  Is the KPA1500 cooling and heat
sink adequate?  Personally if I owned this amp I would leave the fan on at a
tolerable speed 100% of the time.  Did you use the amp during the RTTY
contest last weekend?

It would be nice to know why this problem is occurring and if Elecraft are
working on a fix.

Viggo,

How do you propose to connect the SDR IQ to the KX3?
The KX3 does not have an IF output - in fact the KX3 IF is either at 
baseband or 8kHz if you turn on the 8kHz shift in the menu.

The KX3 DOES have the RX I/Q output which you can connect to a computer 
soundcard or the KX3 for a panadapter display.

Yes, the SDR IQ works fine with the K3 which has an IF output at 8.215MHz.

Guys

the problem here is not who use PL259 or what coaxial is using. I think
Peter and most of us, and mostly if you do contests, is not that, we are
using good coax and connectors over the years and no problem with other
radios or amplifiers, thats what Peter said.

If you are in a contest, you prepear your station to not fail. Robust
radios and amplifiers, not only pretty ones

Hopefully guys in USA will have this problem solved *easily*

But what about if you dont live in USA?  I didnt buy Expert 1.3K amplifier
because many owners told me about it?s fail. Is very expensive and dificult
to deal with customs to take it to USA and back to Uruguay to repair it.

So, KPA1500 is a robust amplifier?  Of course always will be a problem, but
is 1% or 25% of the cases?

And I dont want parts sent by Elecraft to fix it, I want an amp that not
fail

As time permits, we're trying to better characterize the RF noise that
plagues stations at various locations. 

So far, data collected during this informal survey has taken the form of
verbal descriptions. Scope traces or digitized samples would be much more
helpful, since they'd show the actual waveforms. We could then look at how
to better suppress the noise profiles, pulse widths, and rep rates
encountered by stations surrounded by modern appliances, vehicles,
peripherals, lighting, etc. Many of these didn't exist decades ago when the
first noise blankers were designed.

On a K3 or K3S, the best place to capture noise signals would be at the
output of the first MC1350 in the KNB3's amplifier chain. In the presence of
strong noise, the signal at this point is likely to produce a visible scope
trace, or a good sample using an RF digitizer. The latter would have to do a
good job at the IF, 8.215 MHz.

On a KX3, the RX IQ outputs should work, assuming the noise signal is quite
strong. As the RX IQ signal occurs at base band, a much lower-bandwidth
scope or an audio-class A-to-D converter would suffice. 

Spectral data would also be of use in both cases.

I don't have any specific recommendations for equipment or software. But if
you have the means in hand, as well as a noise problem worth capturing, feel
free to contact me directly. Please include photos or screen captures as
well as details on what remediation techniques work -- and don't.

FWIW, I use NO-OX-ID contact grease on my PL259 connectors. This allows 
very tight snugging by hand, no need of wrenching.

During lightning season I frequently connect/disconnect my rig and tuner 
cables. The fine film of lube on the connector threads makes a big 
difference. Without it? A real PITA, not to mention wear and tear on the 
the SO-239's.

Amphenol 83-1SP connectors are great however I have a number of Andrew
44ASP, L44P and L45P connectors in my system and I also consider to be very
high quality UHF connectors.

If you live in North America, the ONLY good PL-259 connector is one that 
labeled Amphenol 83-1SP.  Most others are JUNK.  I'm told there are some 
other decent brands sold in EU.

I never wrench. I just wiggle the connector as I tighten it and it tightens
down into the v grooves tightly. Almost have to use a pliers to unscrew it.

Drew and all,

I have changed the subject line to something more akin to the current 
discussion.

Have you considered adding a coax switch?  Turning to switch to an open 
position (or better yet to a dummy load) when the radio is not in use 
will provide protection and is a lot easier than removing the connectors.

Don W3FPR

Message-ID: <BYAPR16MB2968366339BCB2092ED656DC8C620@BYAPR16MB2968.namprd16.prod.outlook.com>

I experienced a very brief power transient on my house 120 VAC supply.  My KAT500 remained powered but my KPA500 dropped off with the fan running.   No real concern about either response.  What was a surprise was that my setting for Band Change - NORM had reverted to Band Change - STBY.   This setting had been changed several days previously and the KPA500 had not been power cycled until the unexpected power transient.

When are changes to KPA500 menu settings saved to NVM?  What I observed would be explained if settings are not saved until normal power down.  If the settings should be saved at the time they are made I'd like to know why this setting was not remembered.

Thanks and 73,

I always worry about what I don't know with this kind of discussion that
seems to dive into entrenched positions of pedantic certainty. Since I love
my KX3 and other Elecraft products, as well as various microcontrollers, I
was concerned that I'd missed something about RS232 which I've used for
decades. So I did a little research. And let me tell you there is so much
information out there that a pedant can basically shut down any discussion
as being inaccurate! Don't dare talk about DB9 connectors on equipment
because you probably mean DE-9P!

Reading the RS232 standard(s), it is clear that any multi-point
implementations are not technically RS232 compliant and require
non-standard wiring and/or software and hardware support that is not in the
specification. Directly connecting standard's compliant equipment will be
hit and miss and could damage some devices - strict compliance to RS232 is
short-circuit protected between pin pairs, but many devices are "sort-of"
compliant. But if you control all sides, then proprietary implementations
could be easily done. Again, that would not technically comply with the
standard. On the other hand, RS232 and RS423 support a multi-drop (multiple
listeners, one sender) format in some cases, which only allows 1 bus driver
and up to 10 receivers.

BUT. There have been many variations over the years, along with
similar-seeming RS485 which is multi-drop. RS485 is wired in a similar way
but is a current loop interface instead of voltage based.  I also found
RS422 which is a long distance "drop-in-replacement" for RS232 and that has
a multi-drop version, but there seem to be so many different flavors of
wiring, it may as well be proprietary at that point.

I've found and reviewed a few dozen of the many, many specifications for
serial communications that are similar to RS232 and can find none that fit
the impression some of the earlier posts gave of having multiple devices
communicating back-and-forth on the same physical RS232 connection. The
talk of sharing connections with boxes that multiplex over an RS232
connection led me to find the products that speak SDLC to a device that
then communicates with a set of RS232 devices. I hardly think that is the
same thing, since although a single RS232 is required on the computer, it
is not speaking directly to the devices on the other end.

I looked up the Bisync protocol as well as the Uniscope equipment. It looks
like although they did use what is called RS232 connectors and wiring, they
did not follow the specification, so standards complient RS232 devices
wouldn't work in a multi-drop setting.

In summary, it seems that a degree of liberty in the use of the terms and
standards results in confusion and folks arguing across each other. There
is a large difference between what might be possible over wiring that
otherwise conforms to RS232 but is unrelated to the standard which is a
point-to-point standard for linking two devices. Then if you overlay
proprietary protocols as used by Uniscope, IBM, et.al along with the many
almost RS232 standards and we get the situation where some insist that
RS232 supports multi-point networking while others claim it doesn't. I
think the bottom line is that any fancy connections (beyond what Elecraft
specifies) between Elecraft devices will need additional software and/or
hardware to support.

I'm fond of BNC connectors for a number of reasons ?

I suggest having a look at the Morse Express website.
You'll find -lots- of interesting stuff.  I have bought a
number of their SO-239 -> BNC conversion kits, stock
#OP-SB 1 or OP-SB 2 and use them on many items.
Examples are the Elecraft directional couplers and
my K3s.

Have a look ?

exist?  If so, where can I obtain it?

Message-ID: <BYAPR16MB2968AF8470B1BF4CA4819A5F8C620@BYAPR16MB2968.namprd16.prod.outlook.com>

"The?talk of sharing connections with boxes that multiplex over an RS232?connection led me to find the products that speak SDLC to a device that then communicates with a set of RS232 devices. I hardly think that is the same thing, since although a single RS232 is required on the computer, it is not speaking directly to the devices on the other end."

Don't know if this is related to the description of my interface but, in case it was, here is a bit more detail:

I use a relay to switch between 2 different RS232 transmitters.  One is the routine interrogator of the RS232 receiver, the other is switched in circuit when I want to send a non-routine command to the receiver.   The receiver doesn't know where the command came from and it doesn't care.  The routine interrogator doesn't know it was taken out of circuit because the TX line is only stolen in a gap between its routine interrogations.

As an example - I can configure my system so the KAT500 Utility is the routine interrogator of my KAT500.  When I change my TX frequency my controller switches the RS232 transmit source from the PC to my Arduino which sends the KAT500 a new frequency.  That frequency command is in a gap between the routing KAT500 Utility interrogations.    

My interface actually has 3 multiplexing relays  - one for the KAT500 interrogator (KAT500 Util or my interface), one for the KPA500 interrogator (KPA500 Util or my interface), and one for my TS-590 interrogator (OmniRIg or my interface).  

Works perfectly and, to the best of my knowledge, no RS232 standards were damaged.

(I wrote all of that without a single mention of "polling").

Dave,

Open the KAT500 manual to page 5 and see the cabling diagram depicted there.

There is no relationship between the K3 and P3 for considerations with 
the amplifier and ATU.

If you have a K3S - the P3 connects to the P3 with the RS232 connector 
and not the ACC connector, so there is no conflict.

If you have the K3S or a K3 upgraded with the KIO3B, then download the 
latest P3 manual and look at the cabling on page 5.  You will need the 
CBLP3Y to connect it as shown there.

73,
Don W3FPR

Don et al:

That is the? best idea!?? Plus if one has a adequate outside lightning 
protection system, properly bonded to the AC mains, and then disconnects 
inside where they use a coax switch with gas discharge tubes and a 
grounding position, they are negating part of the system protection.

Hello Elecrafters.,

Have some of you connected an SDR IQ to the KX3,, ( use as an Panadapter
with Spectravue) ?

Work very well with the K3........

Sorry to hear this happen Peter, especially during a contes. LDMOS devices
are suppose to be pretty tough and the KPA1500 is not pushing their limits.
There are videos of a different LDMOS showing it to be indestructible:
https://www.youtube.com/watch?v=8ziYqjMQGEQ  Is the KPA1500 cooling and heat
sink adequate?  Personally if I owned this amp I would leave the fan on at a
tolerable speed 100% of the time.  Did you use the amp during the RTTY
contest last weekend?

Do not trust PL-259 connectors installed only "finger tight". Today many 
of those PL-259 connectors "look good" but are really poor quality 
connectors.??? ALWAYS snug the PL-259's with a pair of 4" channel lock 
pliers.?? You'd be amazed how many strange issues will go away.

Not saying this is or was the cause of failure, but I've seen it and 
experienced it too many times.

Also, for other reasons, I run the ALC from my KPA500 to my K3S.?? 
Again, another issue of concern resolved.

Hi Peter,

I'm sorry to hear about this failure and deeply apologize for the problem. 

I'll follow up with another email to you to diagnose what actually happened.


In any case we'll deal with it quickly and get your amp repaired asap.

I drove my AL-80B with 60 to 80 watts for some two years.?? Absolute no 
issues of concern.??? In April of 2018 I purchased a new KPA500 and put 
it in place of the AL-80B.?? I drove the KPA500 with my K3S at 15 watts 
for some 2 weeks.? Then reports of "fuzzy audio" surfaced.? The 2 tone 
test revealed excessive IMD.? I contacted Tech Support and they arranged 
to send me a LPA3 and a KPA3A.?? These were installed and all was well 
for about one week.? Then again the reports of "fuzzy audio".? I 
contacted Tech Support again and they said "send it in".?? The service 
report indicated they replaced the KPA3A with a rev E which is reported 
to be more stable.? An interesting comment on the Elecraft Service 
report; "Due to failure of the stable rev E amp, this indicates 
something in the shack.?? Possible kickback from and amplifier.?? It is 
likely to happen again if the root cause is not found. ........"??? 
UGH...folks, the amp is a KPA500!???? >> HOUSTON - DO WE HAVE A PROBLEM?>>

In the discussions via e-mail and here on the reflector which followed, 
I learned of others which experienced the same type issues.? I asked 
"what's the solution".?? Interestingly the answer came back [I don't 
recall from whom}? "stay away from 15 watts". Since then I have driven 
my KPA500 with 20 watts .....PLUS? I have connected and engaged the ALC 
from the KPA500 to my K3S.? This is a menu item in the K3S.? Now some 
may not like the ALC connection and activation.

My thinking is that IF there are any spikes originated with the rise of 
the CW signal or voice signal this may overdrive the amp.?? With my P3 I 
see this A LOT on SSB signals on the bands which exhibit initial ALC 
overshoot.? This is both on CW and SSB. ?? Makes me wonder what does the 
input impedance of the KPA500 does when hit with a millisecond or so of 
excessive drive? ? Not long enough to activate the attenuator or throw a 
fault signal. I do know that tube amps reflect to their input the 
effective tuning of the output. ? Could this be an issue with solid 
state amps where the input impedance goes to zero thus placing in effect 
short on the driving transceiver? ? Mind you not long enough to throw a 
fault signal but........what does it do to the driving stage? ? ? I've 
not measured it and am not exactly sure how to accomplish this.? It may 
not be the issue at all.?? Perhaps some of you more technical gurus can 
expound further on the topic.

I do know factually since the change to the KPA3A? rev E, and I 
activated the ALC between the KPA500 and my K3S the issue has not reared 
its ugly head. ? Lets hope it doesn't.

All in all, I am VERY pleased with Elecraft Tech support and extremely 
pleased with my K3S, P3, KPA500 and KAT500.? A winning combination.?? 
But I'm still walking on eggs? and hoping none break.

I agree with you re PL-259s. I follow best practices in this regard.
Quarter-turn with channel-locks after finger tight, Amphenol 83-1SP,

Do not trust PL-259 connectors installed only "finger tight". Today many of
those PL-259 connectors "look good" but are really poor quality connectors.
ALWAYS snug the PL-259's with a pair of 4" channel lock pliers.   You'd be
amazed how many strange issues will go away.

Not saying this is or was the cause of failure, but I've seen it and
experienced it too many times.

Also, for other reasons, I run the ALC from my KPA500 to my K3S. Again,
another issue of concern resolved.

If you live in North America, the ONLY good PL-259 connector is one that 
labeled Amphenol 83-1SP.? Most others are JUNK.? I'm told there are some 
other decent brands sold in EU.

RIGHT. And always be VERY careful about how you solder them, especially 
the shield.

Who uses PL-259s?  They suck.  I ordered my K3S with Ns and really should
have specified DINs.  But, that is a retrofit project for another day.

Bob and all,

I think this problem is not so much with the amplifier, but the K3/K3S.
Consider that the switchover from the low power amplifier to the KPA3 is 
in the 12 to 15 watt range.  That is where the LPA is generating about 
all the power it can produce.  Above that range, the KPA3 kicks in and 
everything is "loafing along".

Oh yes, aside from that, some amplifiers do fail for various reasons - 
and I think we are mixing failures of the K3/K3S with amplifier failures 
in this thread.

73,
Don W3FPR

I don't contest in RTTY (I don't use that mode other than for Dxpeditions)
and rarely even do FT8. I mostly operate CW and a bit of SSB and that's it. 

I have no idea why it would fail. I did have some issues in the past with
antennas going stupid on me or the HF-Auto tuner failing to match when it
was supposed to, but those always hard-faulted instantly. I never attempted
to push RF through more than about a 2:1 without a tuner, and for CW, all my
antennas are resonant on the bottom of all the bands. That it happened on 20
where I'm about 1.2:1 is very strange.

Sorry to hear this happen Peter, especially during a contes. LDMOS devices
are suppose to be pretty tough and the KPA1500 is not pushing their limits.
There are videos of a different LDMOS showing it to be indestructible:
https://www.youtube.com/watch?v=8ziYqjMQGEQ  Is the KPA1500 cooling and heat
sink adequate?  Personally if I owned this amp I would leave the fan on at a
tolerable speed 100% of the time.  Did you use the amp during the RTTY
contest last weekend?

Viggo,

How do you propose to connect the SDR IQ to the KX3?
The KX3 does not have an IF output - in fact the KX3 IF is either at 
baseband or 8kHz if you turn on the 8kHz shift in the menu.

The KX3 DOES have the RX I/Q output which you can connect to a computer 
soundcard or the KX3 for a panadapter display.

Yes, the SDR IQ works fine with the K3 which has an IF output at 8.215MHz.

73,
Don W3FPR

Guys

the problem here is not who use PL259 or what coaxial is using. I think
Peter and most of us, and mostly if you do contests, is not that, we are
using good coax and connectors over the years and no problem with other
radios or amplifiers, thats what Peter said.

If you are in a contest, you prepear your station to not fail. Robust
radios and amplifiers, not only pretty ones

Hopefully guys in USA will have this problem solved *easily*

But what about if you dont live in USA?  I didnt buy Expert 1.3K amplifier
because many owners told me about it?s fail. Is very expensive and dificult
to deal with customs to take it to USA and back to Uruguay to repair it.

So, KPA1500 is a robust amplifier?  Of course always will be a problem, but
is 1% or 25% of the cases?

And I dont want parts sent by Elecraft to fix it, I want an amp that not
fail

As time permits, we're trying to better characterize the RF noise that
plagues stations at various locations. 

So far, data collected during this informal survey has taken the form of
verbal descriptions. Scope traces or digitized samples would be much more
helpful, since they'd show the actual waveforms. We could then look at how
to better suppress the noise profiles, pulse widths, and rep rates
encountered by stations surrounded by modern appliances, vehicles,
peripherals, lighting, etc. Many of these didn't exist decades ago when the
first noise blankers were designed.

On a K3 or K3S, the best place to capture noise signals would be at the
output of the first MC1350 in the KNB3's amplifier chain. In the presence of
strong noise, the signal at this point is likely to produce a visible scope
trace, or a good sample using an RF digitizer. The latter would have to do a
good job at the IF, 8.215 MHz.

On a KX3, the RX IQ outputs should work, assuming the noise signal is quite
strong. As the RX IQ signal occurs at base band, a much lower-bandwidth
scope or an audio-class A-to-D converter would suffice. 

Spectral data would also be of use in both cases.

I don't have any specific recommendations for equipment or software. But if
you have the means in hand, as well as a noise problem worth capturing, feel
free to contact me directly. Please include photos or screen captures as
well as details on what remediation techniques work -- and don't.

FWIW, I use NO-OX-ID contact grease on my PL259 connectors. This allows 
very tight snugging by hand, no need of wrenching.

During lightning season I frequently connect/disconnect my rig and tuner 
cables. The fine film of lube on the connector threads makes a big 
difference. Without it? A real PITA, not to mention wear and tear on the 
the SO-239's.

Amphenol 83-1SP connectors are great however I have a number of Andrew
44ASP, L44P and L45P connectors in my system and I also consider to be very
high quality UHF connectors.

If you live in North America, the ONLY good PL-259 connector is one that 
labeled Amphenol 83-1SP.  Most others are JUNK.  I'm told there are some 
other decent brands sold in EU.

I never wrench. I just wiggle the connector as I tighten it and it tightens
down into the v grooves tightly. Almost have to use a pliers to unscrew it.

Drew and all,

I have changed the subject line to something more akin to the current 
discussion.

Have you considered adding a coax switch?  Turning to switch to an open 
position (or better yet to a dummy load) when the radio is not in use 
will provide protection and is a lot easier than removing the connectors.

Don,

Thank you for helping, and thank you for indulging a newcomer to 
Elecraft hardware, beyond the K3/P3.

As you can imagine I am excited to get this connected up, but being very 
careful!  Hence the questions here, and thank you again!

To clarify what I have now:
I have a K3, (not S, with the RS-232 port, not USB), for external 
communications.

Can you expand on:

"There is no relationship between the K3 and P3 for considerations with 
the amplifier and ATU."

What does this mean exactly?

My assumption set:
I am expecting the K3 to provide some sort of signal, (other than RF 
into the amp, from the K3, in order to provide band switching 
signaling), in order for the KAT/KPA to know what band they are supposed 
to be on, and then switch to that band and tuning  solution.

Is that a correct assumption on my part, or in my case, (not a K3S), 
does the amp/tuner derive band information from the RF leaving the K3?

I bought used, and am unsure what the original owner had-- a K3 or K3S, 
so I may not have the correct cable set for a K3.  I will query the 
previous owner tomorrow about this.

I am also giving a lot of info here that may not be relevant, as I am 
assuming I know almost nothing about connecting this setup together, 
given I can't locate a cabling diagram for the entire setup I have.

Again, thank you for the assistance here...

73s and thanks,
Dave (NK7Z)

Right Gary, a 7/8 EIA flange would be a much better radio connector:)

Actually I have a few 4.3-10 connecters, they should be an easy swap with
SO-239/N jacks but I have yet to use one and I certainly would not do this
on my K3S.

Who uses PL-259s?  They suck.  I ordered my K3S with Ns and really should
have specified DINs.  But, that is a retrofit project for another day.

 I use a 64 key Genovation Keypad via serial and not via the P3, That way the P3 can have a keyboard plugged into it.
At one time I saw where somone had used a raspberry Pi to make a interface to go between two keyboarddevices and the P3 but I haven't found it again (that seems the best way to do it)

 Hi Bob,

On a related subject, but not quite what you asked about, if you are 
just looking for a way to fire off macros at the K3, and have the SVGA 
for the P3, see:

https://www.nk7z.net/adding-external-keypad-k3/

This is a way to use a 64 key Genovation keypad to fire off complex 
macros to the K3/P3, using a single keypress, from a dedicated pad, as 
opposed to having to type in macros, or triggers to the K3/P3 radio 
complex via a keyboard.

An example of what can be done would be the "Offset +" macro-- I press a 
single button on the Genovation keypad, and the Radio drops into split, 
the P3 shifts the CW signal to the left side of the display, while 
setting the bandwidth for the P3 to 6 KHz., to show the top part of the 
pile up, and then sets the K3 bandwidth to whatever I have set in the 
macro, all with a single button press.

I currently have 32 macros programmed up, some for power level setting, 
switching VFOs, triggering the K3 memories in CW or Voice, setting K3 
bandwidths, contest exchanges, IDs, etc.

There is a spread sheet of macros you can download for use within the 
Genovation setup at that URL as well.? I seldom even touch the K3 now, 
but to tune, or turn it on, or off.? Most of my K3/P3 operations comes 
from the Genovation keypad.

73s and thanks,

Good Evening,

 ?? After a snow filled week the forecast is for sun and then more 
snow.? The solar flux has risen by one full point.? However, a solar 
breeze is due to hit on Tuesday.? There is another contest this week.? 
The International DX CW contest.? If I can find room on 20 meters I will 
run the first net.? Otherwise the second net will start just as the 
contest ends.? Another good reason for having the second net start at 
0000z.


Please join us tomorrow on:

14050 kHz at 2200z Sunday? (2 PM PST Sunday) If possible.
 ?7047 kHz at 0000z Monday? (4 PM PST Sunday)

73,

And now there came both mist and snow,
And it grew wondrous cold:
And ice, mast-high, came floating by,
As green as emerald.

And through the drifts the snowy clifts
Did send a dismal sheen:
Nor shapes of men nor beasts we ken?
The ice was all between.

The ice was here, the ice was there,
The ice was all around:
It cracked and growled, and roared and howled,
Like noises in a swound!

As is often the case on reflectors, things often drift of the main topic. RS232, 422. , and RS485 are among a number of electrical specifications that permits the transmission of serial data. While each has certain inherent limitations due to the electrical specification, it is really how the software involved implements the interface can be utilized.

No, a bit paranoid perhaps but I disconnect the rig entirely, including 
p/s cable. It's not too bad since I'm mostly a CW operator and don't 
usually have a lot of other peripherals, SDR, computer, etc. connected 
to the K3.

BTW, I don't trust the Amphenol name particularly after getting a bad 
plug that wouldn't thread correctly (only realized after soldering the 
thing on the coax and trying to use it. Arggh!). Amphenol is offshore 
product now.

I use a single PL-259 for all the transmitting antennas as a lightning 
disconnect. I can attest to the fact that trouble ensues if I forget to 
tighten it with the pliers. I crashed my computer during the contest 
today. Twice, before I caught on.

Many thanks to all!  I figured it out!  I was looking to move the band 
data and thought it came from the data connection, not the AUX connection.

My own preconceived ideas were holding me back from understanding the 
process...  Broke it down into little single steps...  Connected 
everything that way, and it worked first time...

With everyone's help I finally got past the assumptions set I had... 
Now all is well.

What an absolutely cool little amp this is...  It is so quiet...  I am 
used to large clunking amps...  First time I have operated full break in 
on CW!  So nice...

The fellow I bought it from is getting a KPA1500...  Can't wait for that 
one...

THANKS TO ALL that helped!

It's really a question of how portable you want to be.

Do you want to travel super-light but you've got the luxury of time to
set-up? Or do you want to be able to make contacts when stopped just for
a minute or two? Or do you want to work QSOs while
pedestrian/bicycle/equestrian/etc. mobile?

For my KX2 I use everything from an MFJ multi-band pocket whip, a couple
of pieces of non-resonant-length wire, a magnetic loop, to a 26ga.
20m/40m/80m dipole I deploy on a 10m fiberglass pole.

Two picture examples are on the bottom of my QRZ page. 

1.  Just a wire up into the beach umbrella and over to a 16 foot fiberglass pole,with my counterpoise. South Carolina Ocean beach.

2.walking along Grismey Island, in the arctic circle with a mfj whip and counterpoise dragging.

Too bad nobody in EU I worked cared about IOTA.

Stiction of non lubricated threads can give a false sense of tight 
connection. PL259/SO239 in particular can have poor contact through the 
ground conductors while the thread seems tight.

When the threads are lubricated stiction does not occur and hand 
tightening always ensures that the front ring of the plug is butted 
against the mating surface on the SO239; and that the rear lip of the 
shell is firmly butted against the short threaded section at the back of 
the plug. These two narrow ring surfaces with relatively small contact 
area are essential to good ground connection in the PL259.

Dave,

I see that you have it figured out.

As to your question - the K3 and P3 connect together using the IF out 
coax and the RS-232 connection.

The KAT500/KPA500 connect using the AUX cable - that is no 
interconnection between the P3 and the KAT500/KPA500, they are entirely 
separate.

Yeah! I have a Daiwa CS401 that I wanted to use to switch an antenna 
between to K3s. The isolation is so poor that 95 watts from one radio 
activates the high RF receive level on the other. Substituting a DELTA-4 
solved the problem.

I  use the Alpha Delta Series.  They have SO-239 and "N" connector models, two position or four position.  For the price difference, I always get four position.

They are not only well built switches, but they do have surge protection (gas) with a replaceable pill.  Their best feature is the very high isolation they offer:

30 MHz  >60 dB
150 MHz >50 dB
450 MHz 50 dB 

And dB Loss:

30 MHz  0.1 dB
150 MHz 0.15 dB
450 MHz 0.5 dB

So, I wish these could be remotable.  However, they are the best switches I've found for a reasonable price, and I have many of them in my station.

Oh yes, on the outside of my house, I have polyphasers.

Message-ID: <70136273.2229.1550418814653@wamui-marley.atl.sa.earthlink.net>

Steve,

For portable ops from a fixed location, consider a multi-band (through use of insulator links) resonant dipole.

High-performance antennas for camping and backpacking have been my principal interest in ham radio for 50 years.  Upon request, I can send a pdf file that describes a seven-band (40m to 10m) dipole that is easy and inexpensive to make, and durable for frequent set-up and take-down. I have used it in one form or another with great success for almost 40 years.

Thanks Don, that was what I needed to hear on your first post.  After I 
figured out that nothing goes through the P3 from the K3 to the KAT500, 
things made a lot more sense...

What a nice setup I have now...  I will be selling my ALS-1306, and 
Palstar HF-AUTO as a result of getting this little amp...  Three db 
difference is nothing to worry about, so 500 watts is great...  Got a 
chance to use it today on the EU opening on 20...  How nice it is in 
CW...  I have never run full break-in, over the past 50 years of being a 
ham...  Should have tried it long ago!  :)

Thank you for the help!

No, a bit paranoid perhaps but I disconnect the rig entirely, including 
p/s cable. It's not too bad since I'm mostly a CW operator and don't 
usually have a lot of other peripherals, SDR, computer, etc. connected 
to the K3.

BTW, I don't trust the Amphenol name particularly after getting a bad 
plug that wouldn't thread correctly (only realized after soldering the 
thing on the coax and trying to use it. Arggh!). Amphenol is offshore

adjustment is so easy a caveman can do it. And they work great. I bought a
long gun case and store all the elements, band modules,coax, balun, and
tools. Just grab and go. No hiking, just drive up locations for these old
bones. Read EHam reviews and check Pars site for more info.

Message-ID: <2FC55BD6-760F-4F77-96C5-2AC5A6E3E259@law.du.edu>

Any experience with how long the K3?s internal battery should go before replacement?

My K3, assembled in late 2013, lost six hours on the clock over the last couple of weeks.  After correction it seems to be running well enough, but I wonder if this is an indication that the internal battery is due for replacement.  I would rather not open the case unless I have to.

In case it matters I leave the K3 powered off for weeks at a time ? but I believe the internal battery is not rechargeable so that shouldn?t be the culprit . . .

In addition, I still have one K2/10 for sale as a result of my downsizing program.  Inquiries off-list, please.

Tnx, as always . . .

Bill,
We used the "slip-ons" to have quick reconfiguration of monitors on a live 
remote (TV) truck when we were still using UHF connectors for video.
We had no failures that I remember - remote live trucks live in a very 
hostile environment!

We used the UHF slip-ons until the conversion to BNCs beginning in the early 
70s

Thanks, George.  Since sending my earlier post I checked the date -- and it's off by 19 years.  It shows a date in '00.  I bought the rig in '13.  From that I'll bet the power to the calendar and the clock both just went out for a while and they reset to their defaults.

The Manual seems to say that the battery is used when the rig isn't powered on, which would explain a battery drain quicker than usual for me, though there is some ambiguity in the text.  Your experience suggests that may be right -- unless my rig experienced some other kind of problem.  The manual also says the battery should last two to ten years depending on the type of battery, with no mention of usage -- sort of wide error bars, methinks.

Cheers,

Ted, KN1CBR

    My K3, built in September 2010, is still on its original battery, and 
    keeping good time.  It is on about 12 hours a day, though - and I don't 
    know if the clock runs on 12V when it is on, which would save the

Message-ID: <010701d4c6ff$a1bf5ca0$e53e15e0$@videotron.ca>

Hi,
I use a Kat500 with my K3 and KX3.  However, I have a number of other radios which I would like to use with the Kat500.  So I'm looking for a antenna switch that can change inputs in some way based on an electronic signal.  The signal can be via serial device, or network doesn't matter.  Anyone know of such a programmable switch? 
Thanks, Tom

Subject: [Elecraft] Slip on adapters on PL259s

Here comes the flames:? I use slip on adapters on my PL259s that connect 
my rigs/tuners/etc. to the outside world on my bulkhead. I have been 
using this method for over 30 years and NEVER had a connector associated 
failure. It allows for quick connect/disconnect when shutting down for 
thunderstorm related issues. I use RG8X for all indoor coax duties and 
run the KPA500 - so no power levels requiring heavier cable. I do snug 
PL259s on equipment slightly with pliers.

Fact is, the only coax failure I have had of recent note, was the poor 
quality patch cable between the P3 and K3. It was long ago replaced with 
a Mil Spec cable from my junk box.

I do use a number of Daiwa 2-position coax switches for various 
purposes. Any comments on coax switches?

At work (RF lab), dBm power units let a feeble-minded engineer :-) use 
plus/minus rather than times/divide with Watts for calculations.

For isolation and other calculations in the ham shack where Watts are 
used, a few python one-liners useful.  (Python is free and runs on 
Windows, Mac, linux.)  When in python, copy the following:

from math import *
w2dbm = lambda x: 10 * log10(x/10) + 30
dbm2w = lambda x: 10 ** ((x-30)/10)
iso = lambda pwr_W, iso_dB: dbm2w(w2dbm(pwr_W) - iso_dB)

and now something like

 >>> iso(1500, 60)
0.001500

tells you that 1500 W with 60 dB isolation leaks 1.5 mW to the other port.

Does dividing 1,500 by 10 to the power of 6 really need a computer and a Python script?  Why not just move the decimal point 6 times?

Thanks for the math stuff! 'Specially that last line. Good to know.

Also, some emails asked where I get/what is a slip on PL259. Go here:

May be others, but that is where I got my newest ones.

Bad example. :-)  Use messier numbers.  General shack use for quick 
conversions is the point.

I generally do DBs in my head. Just remember with power 3 db=2X,  6db-4X, 7DB=5X and 10 db=10X. It scales from there. Every 10 db is a factor of 10. 60 db is a factor of one million. Just divide 1500 by a million.  

For voltage the scale doubles so 20 db is 10X, 6 db is 2X, etc.

TopTen has a nice A/B switch with pretty good isolation characteristics. See: https://toptendevices.com/products/ab-station-selector/ <https://toptendevices.com/products/ab-station-selector/>
It requires a 12V signal for switching, I believe.

Array Solutions also sells some devices that may be of interest.

A low-pass filter will not change RFI either coming into the shack or 
going out.  There are low-pass filters in all transceivers produced by 
Elecraft (and most other manufacturers), and they are in both the 
transmit and receive path.
The current FCC requirement is for the 2nd harmonic be suppressed by 43 
dB over the fundamental.
Low pass filters come from a past era when the FCC requirements were not 
as stringent and TVs responded to those higher order harmonics from 
amateur transmitters.  That is no longer the case.

Considering receive, we do have many sources of unintentional radiation 
which is present in the HF spectrum, and other than locating and having 
the offending device turned off, there is not much we can do about it. 
Although if it is interfering with licensed operation, there is recourse 
by cooperation with the FCC.  The products giving problems range from 
inexpensive switching power sources (read wall-warts) to control 
circuits in many household appliances and other consumer devices, and 
even some lighting products.

If you are operating in an environment like Field Day where there are 
multiple transmitters operating in close proximity, bandpass filters and 
single band antennas are the normal "cure" as well as physical 
separation of the antennas.

Last August, I had my KPA1500 repaired by Elecraft as one PA transistor failed. They replaced both PA transistors and sent it back to me under warranty. Only the RF deck was shipped to Elecraft. The KPA1500 power supply stayed home unplugged during this time,.?
I kept using my backup Amp until today when I removed the KPA1500 from the box and installed it in my shack. I connected everything up and connected the power supply to my 220v outlet.?
Upon powering up the Power Supply, only the AC On green LED lights. Nothing from the HV Supply or LV Supply LEDs on the power supply. The RF deck does not power on.?
I have re-seated the heavy red/black cables several times as well as unplugged and plugged in the power supply several times, however the power supply does not seem to provide power to the RF deck.?
Before I pack it up and ship it back to Elecraft, is there anything else that I should check?

Paul,

Be certain the control cable between the KPA1500 RF deck and the power 
supply is seated properly and the jackscrews tightened.  The fact that 
the KPA1500 power switch does nothing is an indicator that the cable may 
have some problem.

Does the P3 have (or are there plans to add) support for a USB hub on the P3?
This would be very handy for those who want to have a Keypad and a Keyboard connected to the P3.

Hi,

Yes this looks interesting as does the ones from Dewey. It seems that top
ten devices also has a 6 antenna to 1 radio switch.  Anyone know if it can
operate the other way around? 6 radios to one antenna (kat500)?

TopTen has a nice A/B switch with pretty good isolation characteristics.
See: https://toptendevices.com/products/ab-station-selector/
<https://toptendevices.com/products/ab-station-selector/>
<https://toptendevices.com/products/ab-station-selector/>
It requires a 12V signal for switching, I believe.

Array Solutions also sells some devices that may be of interest.

I concur with the comments on the Top Ten 2-way switches. I'm using 
about 10 of them at various places in my SO2R contest station antenna 
and BPF switching networks. They work well and have good isolation. I'm 
also using a 6-way for RX antenna switching. It's simply one port 
switched to one of six, so it will work just fine either way. RF doesn't 
care which way it goes through relays. A nice benefit of the Top Ten 
switches is that they're internally interlocked, so it's electrically 
impossible to select more than one port-to-port configuration at a time.

The Top Ten box just has relays connecting between the input and one of six

driving one antenna. I use Top Ten relay on my expeditions automatically
controlled by their band decoder which is connected to my K3S.

Hi,

Yes this looks interesting as does the ones from Dewey. It seems that top
ten devices also has a 6 antenna to 1 radio switch.  Anyone know if it can
operate the other way around? 6 radios to one antenna (kat500)?

On the basis of my measurements with a Vector Network Analyzer, I am NOT 
impressed with these switches, and consider them poorly designed. The 
major design flaw is that they depend upon the chassis for signal 
return, so the signal path gets increasingly badly mismatched at 15M and 
above. I didn't measure crosstalk, but this design error would certainly 
impact it. I reduced the mismatch by about half by adding braid from the 
coax connectors to the circuit board and following (as best I could) the 
signal path to provide a return. Why? Because the "ground" layer is 
broken under the top layer, so it can't act as a return either!

Someone cited 50 dB as "good isolation." When I replaced my WX0B 6x2, I 
measured isolation of about 55 dB. The replacement, a 4O3A 6x2, measured 
75 dB worst case. And other one I'm using now, the 4O3A Antenna Genius, 
measures better than 95 dB worst case.

If you look inside a well designed power amp, you'll see transmission 
line running from input and output for both TX and RX path. My Ten Tec 
Titans were built that way, and so is the KPA500. You'll also see 
mini-coax jumpers tying sections of the K3 together.

Hi Paul,

If the green AC light is on and the  PS 50V LED is not coming on when you try to power up the amp from the RF deck front panel it indicates that the two boxes are not talking. 

It sounds like the control cable between the amp and PS is not fully seated. Try unscrewing it on both ends and re inserting it firmly without depending on the screws to pull it in tightly. 

As an early field tester for the amp I suspect you may have one of the early pre-release control cables that had slightly long screws and may not seat fully if  you relied on screwing it in to seat it.  In any case, we can also get you a new cable to try after we are back in the office Tuesday.

Yup, I did specify "good", not "great" isolation for the Top Ten 
switches. I'm aware of their limitations. I agree that it's always 
desirable to have 70+ dB port-to-port isolation if you can get it (and 
afford it), but depending on the application it's certainly not always 
necessary. During the phase of my career when I was involved in cellular 
base station RF system design, in which performance was always balanced 
with cost (and guess which one won if push came to shove), I learned to 
do balanced designs that made sure no component was over-specified. This 
experience has carried through to my HF station design.

In my particular case, I'm switching TX bandpass filters that supplement 
the main BPF at the output of the radio to suppress harmonics and noise 
from the amplifier. There's a pair of the Top Ten 2-ways at the input 
and output ports of the TX BPF bank that lets me share a single bank of 
filters between two radios. The filter banks are switched by a 2X6 
switch matrix at each end that has around 60 dB port-to-port isolation. 
The bandpass filters themselves have about 80 dB worst case adjacent 
band isolation, so assuming the I/O switches each have 60 dB or so of 
isolation, that's theoretically -120 dB leakage contributed by the 
selector switches. This leakage is thus about 40 dB down from the worst 
case BPF rejection, therefore negligible.Even if the total switch 
isolation were only 80dB, this would mean the additional power 
contributed from switch leakage would increase the total coupling (and 
therefore decrease the isolation) by only 3 dB. The 2-way switches are 
used to either enable the TX filter bank for the contest bands or bypass 
it for the WARC bands. So putting a 2-way switch with mediocre isolation 
on each I/O port of the selector switches has no effect on system 
performance in the contest bands. Actually, even though the whole 
network is wired with LMR-240 the coax shielding is probably the 
limiting factor for total station-to-station isolation anyhow. I agree 
that there are places where excellent isolation is required, and should 
be specified. Like you, I used to use a WX0B SixPak, but many years ago 
I replaced with a microHAM Double Ten switch, which has isolation 
similar to the 4O3A switch, for this reason.

As for VSWR effects, I've learned long ago that attempting to make 
complex RF systems involving filters and multiple switching points over 
the almost 4 octaves of the HF to 6 meter range look like 50 + j0 on 
every band is an essentially impossible endeavor. Fortunately, 
well-designed transmitters these days are not overly sensitive to 
moderate VSWR loads; as long as there's not a really bad mismatch 
somewhere in the system they should take normal mismatches in stride.

The OP was inquiring about switches that are suitable to switch multiple 
radios to one amplifier input, which implies that only one radio at a 
time will be active. For that the Top Ten switches are plenty good enough.

W2VJN and N3RD from Top Ten Devices are great helpful guys. I have been
using their band decoders for decades and we have both operated from the
same station in St Croix. I also have a Top Ten 6 way antenna relay box
that I only use only on contest expeditions with a single radio. It is
small, light weight and easily fits in my suitcase. This is not a
heavy-duty relay, you cannot run legal limit RTTY though it. Also the
SO-239 center connectors are recessed which might cause an issue with some
crimped PL-259's.  To use their relays for an SO2R station would require a
lot of relay boxes and they claim isolation >40dB. For me a single 2 x 6
box is a better choice, Array Solutions SixPak claims >55dB which Jim
confirmed.

Message-ID: <133E8599-58A9-482E-B636-DA4274565F8C@mac.com>

This last fall I installed the P3TXMON in my P3, using the DCHF-200 coupler.

I guess I never checked this on 40M, but this weekend during the CW DX contest I found that I could not use 40M: I got so much RF entering the PC via the USB port that my logging program locked up and I had to reboot the PC.

Got to thinking about the discussion recently on this reflector about the PL-259 discussion, and checked my installation. The coax was in good shape and properly tightened down to the coupler. However, the SO-239 connectors on the DCHF-200 were VERY loose! Tightened these down, and all is well on 40M again.

Folks using one of the Elecraft couplers might want to check that the SO-239 connectors are firmly tightened down!

I've always wanted to better understand the tweaks/handles that we have
in the noise blanker/noise reduction algorithms in the K3/K3S.  I can
'frob the knobs', until I see some reduction in noise, but I felt it
would be much better to not be flying blind, and be able to know just
what the various modes do and their parameters do, and be able to
actually see some better noise signature to get an idea of whether or
not a particular tweak is doing what I thought it was doing.


I have the Fred Cady book, and it goes into some detail, but I'd like to
see a much better description from the source as to just what all those
parameters actually do, and a means to see it actually happen, on the
P3, or a scope, hooked to the IF out or similar.


I'm plagued with all sorts of noise at my QTH, and I haven't spent much
time trying to hunt it all down.  I feel I need better insight than to
just go around pulling circuit breakers.  Some of the stuff is quite
likely to be off-premise, as well, which brings me back to likely having
to deal with it as best I can at the receiver end of it.


Thanks and 73,

 As time permits, we're trying to better characterize the RF noise that

Dave,

Yeah I'd like to see that too. I'm lucky that my nearest neighbor is 300 
feet away and we have underground power. EVERY noise I've heard on 
either HF, VHF or UHF has originated on my premises.

One of the first things to do is isolate the noise to two sources in 
general.?? (a) inside the house, (b) outside the house.

My approach is to use the 12V battery off of the lawn tractor to power 
the transceiver.? Use the antenna and band which provides the worst 
noise.? Then pull the main breaker for the house. What's the noise 
difference?? If there is little to no difference, the noise is outside 
of the house.? If the noise drops a noticeable amount, that part of the 
noise is inside the house. The MFJ 805 works well for finding noise 
inside the house.

To further look for (a), turn all breakers off and the main back on.? 
Noise should be about the same.? Then add one breaker at a time and 
observe the noise.? Yes, I know this takes many trips between the 
breaker panel and the radio.? When you flip a breaker ON and the noise 
increases, that tells one what circuit and area of the house the noise 
is originating.?? Find it and eliminate it.? Then move on to other 
breakers in the panel doing the same thing.? This is simply the process 
of logically identifying the noise and then applying means to reduce or 
eliminate the noise. If it is outside of the house than an item such as 
the MFJ 852 works well.

The NB and NR functions work well in the K3S but they are no substitute 
for finding and eliminating the noise source.

Great advice. BUT -- when doing this, make sure that all UPS units are 
powered off, both because they are noise sources themselves, and because 
they keep some equipment running that's also likely to be a noise source.

Lots more detailed advice in http://k9yc.com/KillingReceiveNoise.pdf

Another important delineation of noise type is between 1) electronic 
noise, generated by electronic equipment, solar power systems, variable 
speed motor controllers, and switch mode power supplies; and 2) impulse 
noise, mostly generated by arcing on power lines, electric fences, and 
neon signs.

My KX3 has developed a problem after a power interrupt/restore carried out by my mistake. With batteries fitted it will no longer fully power down, it stays orange with (7) ******* stars showing on screen and Delta f light on and OFS and B green lights on. I have to disconnect all power to the unit to fully shutdown ie pull out one battery and no external supply.
i have run utility and down loaded the latest firmware programes several times with no success as per page 25 of the manual. On re establishing power to KX3 either external or battery radio starts up automatically and is working. i would be great full  of any suggestions  from the group.

Bernie,

Do you have a saved configuration file for that KX3 from a time it was 
working properly?

If so, you can do an EEINIT (Reset to Factory Defaults) - see the manual 
for the procedure.

The reset will lose the calibration data and any menu settings that you 
have added.  That is why the saved configuration file is important - 
restore the configuration file using KX3 Utility.

If you have no other recourse, you can request the factory configuration 
file from support at elecraft.com.  Be sure to specify your serial number.

If the EEINIT does not correct it, you can ask for an RSA to send it in 
for service.  If you prefer, it can be sent to the service facility in 
Italy.

73,
Don W3FPR

I used mine this weekend, I am very happy with them.  The headset has a 1/4 stereo phone plug that is quite robust when compared with a 3.5 mm plug and an adapter.  The cable is long and seems sturdy.  Very comfortable over the ear phones with good isolation.  Has a boom mike that I can push out of the way for a CW contest.

I?m glad I bought them.

If I had $195 (headset plus mic plug adapter) to spend and needed a good 
boom-mic headset, I'd buy a CM500 and a couple of bottles of a REALLY 
nice single malt. The only reason I can think of to spend that kind of 
money is if the headphones have REALLY great isolation from room noise, 
and then only room noise was a problem for me (like in a SSB multi-op 
contest station). And I'd do the A/B comparison before plunking down the 
bucks.

There's BS in the product description too -- "1 1/2 feet coiled cord for 
RF suppression" is nonsense. If anything the added length makes it a 
better receiving antenna for radios with RF problems! And there is zero 
magic to 600 ohms -- we haven't matched impedances in audio for nearly 
50 years!? It's simply a low impedance mic, and virtually all mics used 
in ham radio have been low impedance for at least that long.

I've been using a CM500 for about ten years, and the only thing that 
breaks is the cable, because I'm really a klutz with headsets. It's not 
replaceable, and I don't see a note that the cable in this one is 
either. If I'm not mistaken, the excellent Sennheiser headset DOES have 
a replaceable cable.

Hi Jim

I bought several MC500, I am happy with them, but not good isolation when doing multi on SSB

And the foam is shelled very quickly

Here, Don is talking about external low pass filters intended to 
suppress VHF harmonics. If you live in an area where TV signals are 
weak, they may still be necessary. Of course, hardly anyone receives 
their TV service that way any more, and most TV stations have moved to 
the UHF bands, anyway.

The low pass filters in solid state radios and amplifiers are necessary 
because their outputs are untuned, and the nonlinearity of transistors 
generates lots of harmonics, including low order ones. In the days of 
vacuum tubes, the pi network served as an effective filter. The popular 
pi-L was even better.

It might be interesting, during a major contest, to listen on the second 
harmonic, say around 14.120 when there's a lot of activity on 40. Many 
are using solid state amplifiers now, and even 43 dB down may be 
audible.? I've never positively identified one, but a lot of stations 
don't come back to me for other reasons, so it would be hard to tell.

OTA TV is growing rapidly which is why cable companies are hurting. I?ve been exclusively OTA for over 10 years. Also, with the repack a number of stations are being moved back to VHF.

Subject: [Elecraft] [K2] K2 base low xmit power on all bands @ > 10 watts
Message-ID: <1550592190099-0.post@n2.nabble.com>

Hello All,

Let me first state that I do not know how long this condition has existed. I
recently added an LP-100 watt meter to my shack and have noticed low
transmit power on all bands (10 thru 160) when power is set to 10 watts or
greater. I have an KPA100, and with it installed, I see no more than 60 to
70 watts max. My K2 is S/N 3010, and I built it new along with all of the
add-ons. To provide the values listed below I removed the KPA100, and
connected the LP-100 (recently re-calibrated by Larry Phipps) directly to
the K2 base BNC antenna connector, with a DL1 dummy load on the load side of
the LP-100 coupler. For input power, I am using a 13.5 VDC  50A power
supply, supplying power to the K2 via barrel jack J3. With power set to 2
watts, I am reading 2+ watts on the LP-100 on all bands. With power set to 5
watts,  I am reading 5+ watts on all bands. Increasing power to 10 watts
results in the following values (and the internal K2 watt meter coincides
with these values) :
10m = 9.60w @ 2.56A current draw (seen on the K2 internal watt meter
display)
12m = 8.80w @ 2.04A
15m = 9.10w @ 1.74A
17m = 9.40w @ 1.80A
20m = 9.40w @ 1.92A
30m = 9.20w @ 3.14A
40m = 10.10w @ 2.76A (the exception, as 40m is above 10w)
80m = 7.20w @ 2.70A
160m = 7.00w @ 3.12A

When power is further increased to 15 watts, these are the readings:
10m = 12.10w @ 3.00A
12m = 10.60w @ 2.24A
15m = 10.10w @ 2.30A
17m = 11.90w @ 2.34A
20m = 11.50w @ 2.50A
30m = 10.00w @ 4.00A
40m = 9.20w @ 4.10A
80m = 7.40w @ 3.80A
160m = 7.30 @ 4.00A

I have gone thru the 40m transmitter alignment and the transmitter alignment
steps outlines on pages 72 and 74 of the manual. I also ordered and just
replaced (two days ago) the PA transistors thinking this was my problem.
But, the issue persists.

Any assistance will be much appreciated.

Mike,

First, you should not take output from the lower BNC jack when the 
KPA100 is installed.  All RF must go through the KPA100 wattmeter for 
proper power control.  That is why your power output at 5 watts is 
excessive.  Put a boot over the lower panel BNC jack as a reminder that 
it should not be used (unless the KPA100 is physically removed - along 
with all 4 cables).

As for the higher power output, it sounds like your KPA100 wattmeter is 
not properly calibrated.  Go to the KPA100 manual and turn to page 49. 
Do the SWR Bridge Null Adjustment and the Power Calibration (R26 and 
R27) so your KAT100 power is equal to that shown on the LP-100.
You must use a good 50 ohm dummy load (not an antenna) to insure accuracy.

Don W3FPR

Two assumptions that may not hold even in urban areas.  Many cable /
satellite subscribers are "cutting the cord" and going to over-the-air
reception (I use that as a backup strategy when - not if - C*cast goes
down), and because of the FCC's ill-regarded "repacking" scheme where
UHF TV channels above 37 are being "re purposed" for the "broadband"
industries' voracious need for spectrum, some urban TV stations are
going back to their pre-UHF channels.

With that said - I still use the "good old" external low-pass filter on
my K2, rather than have it gather dust in the garage. Better be safe
than sorry.

perhaps you could add to the menu would be ability to switch temp from C

Thanks for all the tips, guys, especially the MFJ meter references.  I
have their ultrasonic sniffer, which helped me point out to the local
power company some dangling insulators.

I have tracked down some on-premise noise sources in the past (in no
particular order):

1) The clock on a Mr. Coffee coffee maker.  It put out a buzz-saw that
could be picked up directly for some distance, plus it coupled to the
power line, for an extra boost of signal goodness.

2) A porch light day/night sensor that screwed into the bulb socket. 
This was amazingly noisy, and only came on at night (natch).

3) A laser printer switcher power supply.  'Nuff said.

4) A doorbell transformer, likely as old as the house (built in 1954). 
It was mounted on the side of a junction box in the basement, and was
exceedingly difficult to track down, as none of the breakers, except the
main, would turn it off. Found out later that the previous owner had
paralleled two breakers in the panel, likely because he kept tripping
one of the circuits in the kitchen or bath -- the effect was that
turning off one or the other breaker had no effect on either of those
circuits.  Thus they were 'mystery' breakers until I pulled the panel
cover and discovered what had transpired.

I've since had an electrician put an extra panel put in, and some
circuits split, because the original panel was completely full with
duplex breakers.  Making plans now to put in a whole-house generator. 
Got the go-ahead from the XYL.  She is tired of all the power outages
we've had in our neighborhood over the last 2-3 years.

Not really DSP, but firmware related. I would like to see a CW Tuning

is in front of me. I don't know if the refresh rate is fast enough, but 
I'd give up a bit of real estate in the waterfall for this feature.

If it's already available and I haven't found it yet in the settings, my 
bad.

Announcing W8FGU Services, LLC now providing build, repair and alignment 
services for the Elecraft Classic Line of
transceivers and accessories as well as the mini-module line.

Hi fellow Elecraft list members, this is Dave, W8FGU and I?m announcing 
(with Elecraft?s blessing) that I am now
providing support services for the Elecraft Classic Line of products 
(K2, K1, KX1, associated transceivers and accessories)
and their mini-module line of products.

As you may or may not know, our legendary guru Don Wilhelm, W3FPR is 
retiring this month from providing these
services for the past 20 years or so. Although Don is retiring from the 
physical support of these fine products, he has
assured all of us that he will continue to provide guidance and advice 
via the Elecraft email reflector for the foreseeable
future.

Through Don?s guidance and encouragement and the numerous discussions 
with Don and senior management at
Elecraft over the last few weeks, I have decided to continue Don?s 
legacy in the Elecraft support arena. Don has been
gracious enough to share with me his business model, pricing, policies 
and procedures so that I may continue to try and
provide the same services he has provided for so many years. I am 
committed to providing the same high quality and
timely service at the same standard Don has set during his tenure.

As this is an ambitious venture on my part, Don has assured me that he 
is only a phone call or email away for when I
need his assistance. And of course, I have the complete support of the 
fine folks at Elecraft. It is with their spirit and
support that we believe we can carry Don?s legacy of servicing these 
fine products of Elecraft engineering, well into the
future.

Elecraft has always been more than supportive of my enclosure business 
since 2006. In that time, I have sold hundreds
of poly-carbonate and acrylic enclosures for their mini-module line of 
products and dust covers for the KX3, PX3 and
KX2. These are all produced by hand in a modest workshop in my basement. 
I have been invited and worked in their
booth in Dayton for the past 12 years. I?ve enjoyed a great working 
relationship with Eric, Wayne and many of the sales
and support staff and look forward to continuing that relationship with 
this new venture.

As many of you know, I am still working full time as a Lieutenant (fire 
fighter/medic) for the Brownstown Fire
Department here in SE Michigan. I will be able to retire in a little 
over two years. But my background has been technical
since high school. My grandfather (the original W8FGU SK) taught me 
about ham radio as a child. He passed away when I was a teenager, but he 
encouraged me to continue my education and I obtained an Associates in 
Electrical Engineering in 1982 and soon began a career as an electronic 
tech that turned into a 20-year programming and IT career in the PC 
software development arena. Although I have been a firefighter since the 
age of 14, my full-time career did not start until October of 2000.

With that said, blowing off the dust on my tech skills and with support 
of Don and all the folks at Elecraft, I am very
confident I will carry on the high support standard that Don has 
established well into the future and for the life of these
products. Please contact me at this email address for any comments, 
questions or concerns. Also please visit my
website: www.w8fgu.com for details of the services I provide and more 
details in how to contact me.

Thanks for the bandwidth,
Dave W8FGU

Welcome aboard, Dave!

I have been working closely with Don Wilhelm while assembling my K2 (serial 7818). We have had quite a few burps,
but with Don?s help I am getting closer to completion. Then I will be able to make MY FIRST QSO as a new ham! The
K2 is my first and only ham radio, and I am excited to finish the build and have a working station.

We are attempting to work through a difficult problem right now. I could include you in email conversations I have
with Don, if you would like, to keep you in the loop.

Again, welcome to the group, and I look forward to working with Don AND YOU.
Thanks, and 73
Don Schroder, KE0PVQ

Announcing W8FGU Services, LLC now providing build, repair and alignment
services for the Elecraft Classic Line of
transceivers and accessories as well as the mini-module line.

Hi fellow Elecraft list members, this is Dave, W8FGU and I?m announcing
(with Elecraft?s blessing) that I am now
providing support services for the Elecraft Classic Line of products
(K2, K1, KX1, associated transceivers and accessories)
and their mini-module line of products.

As you may or may not know, our legendary guru Don Wilhelm, W3FPR is
retiring this month from providing these
services for the past 20 years or so. Although Don is retiring from the
physical support of these fine products, he has
assured all of us that he will continue to provide guidance and advice
via the Elecraft email reflector for the foreseeable
future.

Through Don?s guidance and encouragement and the numerous discussions
with Don and senior management at
Elecraft over the last few weeks, I have decided to continue Don?s
legacy in the Elecraft support arena. Don has been
gracious enough to share with me his business model, pricing, policies
and procedures so that I may continue to try and
provide the same services he has provided for so many years. I am
committed to providing the same high quality and
timely service at the same standard Don has set during his tenure.

As this is an ambitious venture on my part, Don has assured me that he
is only a phone call or email away for when I
need his assistance. And of course, I have the complete support of the
fine folks at Elecraft. It is with their spirit and
support that we believe we can carry Don?s legacy of servicing these
fine products of Elecraft engineering, well into the
future.

Elecraft has always been more than supportive of my enclosure business
since 2006. In that time, I have sold hundreds
of poly-carbonate and acrylic enclosures for their mini-module line of
products and dust covers for the KX3, PX3 and
KX2. These are all produced by hand in a modest workshop in my basement.
I have been invited and worked in their
booth in Dayton for the past 12 years. I?ve enjoyed a great working
relationship with Eric, Wayne and many of the sales
and support staff and look forward to continuing that relationship with
this new venture.

As many of you know, I am still working full time as a Lieutenant (fire
fighter/medic) for the Brownstown Fire
Department here in SE Michigan. I will be able to retire in a little
over two years. But my background has been technical
since high school. My grandfather (the original W8FGU SK) taught me
about ham radio as a child. He passed away when I was a teenager, but he
encouraged me to continue my education and I obtained an Associates in
Electrical Engineering in 1982 and soon began a career as an electronic
tech that turned into a 20-year programming and IT career in the PC
software development arena. Although I have been a firefighter since the
age of 14, my full-time career did not start until October of 2000.

With that said, blowing off the dust on my tech skills and with support
of Don and all the folks at Elecraft, I am very
confident I will carry on the high support standard that Don has
established well into the future and for the life of these
products. Please contact me at this email address for any comments,
questions or concerns. Also please visit my
website: www.w8fgu.com for details of the services I provide and more
details in how to contact me.

Thanks for the bandwidth,
Dave W8FGU

Subject: [Elecraft] K3 Erratic Power Output
Message-ID: <026401d4c8a6$a199e210$e4cda630$@ameritech.net>

Over the weekend I did some more testing.  Here are the results of my
testing.  The power display and SWR indication on the bar graphs are correct
and linear with the power encoder up to 12 watts.  When the PA engages at 13
watts the power goes up rapidly and the power and SWR indications on the bar
graph disappear.  I do not believe it is the encoder. My power readings were
taken with a Bird and a known dummy load.  The same thing happens on antenna
1 or 2.  The power rapidly climbs to over 100 watts as if the was no control
over the power level.  No display of power output or SWR.  

 

Ideas?  Perhaps a trip to California.  Would be warmer than in Illinois.  

 

Larry, WA9MAG

Dave is where I got both of my Hex Key paddle covers.  I looked forward to his KX3 acrylic box carrier but he never made more than a couple of prototypes.  I?ve only ever seen him at Hamvention.

Subject: [Elecraft] [K3] Main/Sub LIN OUT audio levels unbalanced
Message-ID: <20190220001513.6i6esketsdc3qeif@n0nb.us>

I am working with my K3 to record audio from the Line Out jack into the
soundcard.  I am finding that the Sub receiver audio is about 8 dB
greater than the Main receiver audio per the input meter in Audacity
(this is with the antenna connected to a 50 ohm load).  My CONFIG:LIN
OUT is set to NOR 007.  My transmit audio is of equal levels on both
left and right channels per Audacity, which I think exonerates the audio
chain into the PC.  I have option 3 of CONFiG:LIN OUT set to T= 020
(nice addition which allowed me to lower the TX audio presented to the
soundcard).

I have noticed that since installing the Sub receiver last August that
through the speakers (two Realistic Minimus 3.5 models) that the Sub
audio is always louder than the Main audio.  Of course, I adjust the
volume controls to even it out as needed, however, I want to keep the
recording level constant, so I'd like to avoid setting CONFIG:LIN OUT to
=PHONES.  A few weeks ago I borrowed an XG3 from a local and did the
receive calibration on all bands but that made no difference.

Is there a method available to balance the audio levels between the
receivers so the recordings I make with Audacity will be balanced?

Thanks!

Larry, there's a good chance that the SWR bridge (FWD/REFL power measurement)
on the K3 RF Board has a problem with the level scaling feature that
switches on when you command a transmit power level above 12 watts.

Check the K3 RF Board schematic (here I'm presuming you have the K3 rather
than the K3S, but I think the SWR bridge circuits are similar), page 4 of
the schematic package, on the far right hand side for the SWR bridge
circuit.  Near the LM358 op amp voltage followers (outputs labeled VFWD and
VREFL) you'll see a pair of voltage dividers that are enabled by logic
signals /FSCL and /RSCL for higher output power levels.  

I'm going out on a limb here, but if /FSCL is not grounded when you command
an output power greater than 12 watts, the voltage follower on the FWD power
branch may saturate and effectively remove the feedback signal that the
power control loop requires to operate properly.  

The /FSCL signal is generated at the output of one flip-flop in an 8-bit
shift register - if that output won't pull down to ground R53, the lower arm
of the voltage divider in the FWD power level scaling circuit, that may
inhibit the necessary scaling of input voltage to the follower to keep it
from saturating.

The fact that the power control loop appears to work smoothly at commanded
power levels less than the 13 watts indicates that the SWR bridge rectifier
diodes are still functioning properly.  The jump to more than 100 watts
output when you command a power level just slightly greater than 13 watts
tells me the power control loop is getting different FWD power information
than what it expects to see.

Probing the SMD device leads to check that /FSCL is properly asserted when
you cross the 12 watt threshold? I'll leave that one to the pros!

73,
Mike, K8CN

Message-ID: <CAOdpi6Gu6TM+NEwLkpzT_fZd0dcjW9Z-8=_3CTAT86Qb0k_r_Q@mail.gmail.com>

Hi All,
I recently purchased a second hand K3s with sub receiver and without
carefully looking into things, I purchased two KFLA-1.0Khz filters from a
ham off the list here.  I returned to my Ohio QTH (where the rig is) only
to find out the main receiver already has one installed, so I only need one
for the sub receiver.

I am looking for someone on the list that has a KFLA-250 Hz in excess to
their needs that they would like to trade.

Please let me know.
Thanks in advance,
73 de Jim - KE8G

Just for clarification, I was asked by a few of you off line if I would 
still continue building enclosures for the mini-modules and dust covers for 
the KX2, KX3 & PX3. And the answer is yes. You can still order them on my 
website as before. Unfortunately, I had to finally raise the shipping 
prices in some areas due to increases at the USPS. But much to my surprise 
some international First Class pricing went down.

But yes, I'm still selling my enclosure line.

Subject: [Elecraft] K3 XFIL Button

Seems like the K3 XFIL button essentially does the same thing as the DSP width knob. That is, depending on how the user has set up the filter configuration, both DSP and filter selected are pretty much automatic and linked together. Adjusting the width knob will result in a particular crystal filter being selected, and similarly, using the XFIL button to select a filter will automatically adjust the DSP setting.

On occasion, I would like to be able to use a wider DSP setting with a narrower crystal filter, or a narrower DSP setting with a wider crystal filter.  Some 160 meter CW operation with diversity receive would be an example.   It would be nice to have a quick way to do this without having to make filter configuration changes.  So since the XFIL button and the width knob are somewhat redundant, could the XFIL button be divorced from automatically changing the DSP setting, so one could easily and quickly select a crystal filter other than what is set up in the configuration?  I don?t know if it?s possible to offer that with a firmware change. If so, a Normal vs. Independent XFIL button firmware option would give users the choice of how the XFIL button worked.

Ed,

Keep in mind that the DSP provides the ultimate filter width, the one 
situation you asked about - roofing filter wider than the DSP filter is 
already present - just set the filter configuration to "lie" about the 
actual filter width, and the roofing filter will be switched in at a DSP 
width that is wider than the roofing filter.

The other (DSP filter wider than the roofing filter) does not make much 
sense to me.  Yes, in the filter configuration, you can tell the K3 that 
the (for example) 400Hz filter is really a 600 Hz filter, then you have 
accomplished what you desire.

I do not have much use for the XFIL button and never use it. I let the 
Width control (or HiCut/LoCUT for SSB) switch in whichever roofing 
filter is appropriate and consistent with the DSP width I have selected 
and it works well.

The DSP filter width is a "brick wall filter" and you will not be able 
to hear signals outside that bandwidth.

Keep in mind the purpose of the roofing filters.  In a crowded band, the 
roofing filters keep strong adjacent stations from activating the 
Hardware AGC which is there to protect the ADC from overloading.  In 
other words (again using the 400Hz roofing filter example), if you have 
the DSP bandwidth set at 300Hz centered on [150Hz plus sidetone pitch = 
750 Hz], and you have a very strong signal at 850 Hz, you will not hear 
the strong signal because of the DSP width, but it will activate the 
hardware AGC causing the AGC to 'pump' and the receiver sensitivity will 
be reduced as a result of that 'pumping' - even though you cannot hear 
the signal.

As an alternative, you might want to try turning on DUAL PB in the menu 
which will give you a wider passband that is attenuated from the narrow 
filter peak (or focus).  I believe that will give you what you seek.

Don W3FPR

W2KJ  de KX2CW ?  I have a SideKar Plus, and it works exactly as advertised (which is to say: great)!  The SideKar and KX2 talk to each other via 38,400 Baud RS232, and the SideKar effectively functions as a memory keyer?sans paddle input and speed control, as there is no need with the Elecraft radios because of the way the Elecraft internal keyer works: it creates text to send up the RS232, and the KX2 internal keyer speed control is a primary function knob on the front panel

The QRPworks SideKar Plus has its quirks, but I still find it well worth it and enjoyable and easy to use, and it really is plug-and-play.  Also, the [Mac version of the] SideKar Utility was easy to install and use.  I think of it as a memory keyer which makes the most of the KX line?s own already excellent onboard capability

Subject: [Elecraft] A third option for Elecraft service
Message-ID: <057801d4c996$71d37d70$557a7850$@net>

Hello everyone,

     I recently posted a message to the group that I would like to purchase
or build any Elecraft kits out there.  Don Wilhelm asked if I would be
interested in helping in some of the service work he had been doing.  I was
honored that Don would even ask me to help out.  I understand it is becoming
difficult for Don to do all the work sent his way.  We also see that it
takes at least three people to handle what Don has been doing for many
years.  After discussion with Don, I agreed to take on some of the service
load.

     I have been building and using Elecraft gear for at least 15 years.  I
presently have three K1's , my prized K2 #5000, a K3, P3, SP3, KAT500,
K-pod, and loads of smaller Elecraft stuff.   I have built nearly every kit
that Elecraft has offered.  I have been on the Elecraft Builders for Hire
list for many years.  My electronics kit building goes back to 1972 when I
built my Heathkit HW-16 as I waited for my Novice ticket to arrive.  I loved
it so much I have made a career of electronics.  For my day job, I work as
an electrical engineer at a company that designs and manufactures medical
laboratory instruments.   I installed and supervised a surface mount
production line there so surface mount construction does not scare me.  My
specialty is printed circuit board design.

     I have been found in the past at the Elecraft booth at the Orlando
Hamcation.  Prior to that some of us promoted Elecraft at our own tables at
hamfests around Florida.  If any of you have seen the K2 with the
transparent case, that is my handy work.  Just trying to promote the great
radios that Elecraft has made for us.

    So I am available, along with Alan and Dave, to service your Elecraft
products.  Don Wilhelm has agreed to help us with advice and direction when
needed.  Of course, I am more than willing to build any kits that you want
completed (or started.) You can contact me through any of the means below.
I promise honest work, modest fees, and that I will do my best to uphold the
superb reputation of Elecraft support.

Subject: [Elecraft] KPA-1500 tuner question
Message-ID: <00b001d4c996$a7618310$f6248930$@w2irt.net>

Hi all,
Something I noticed this past weekend in the contest about the KPA1500,
especially on 80 and 160, where the internal tuner was needed on antennas
that were above ~1.5:1 SWR. When I changed frequencies into a range that
required retuning, I had to manually press the ATU control and initiate a
tune sequence, or else when I was auto-sending CW my call would get cut off
as the tuner set its needed values.

Since I'd memorized the entire band(s) ahead of time, is there a way for the
memorized tuning solutions to load on QSY, rather than on RF application? It
really slowed me down as I was S&Ping my way through the low bands on Friday
night.

The XFIL button is my least favorite feature of the K3 user interface.
I always use the knob to change the bandwidth ? except when I accidentally don?t hold the button long enough when activating or deactivating the APF, which I do a lot.

I experienced the same thing, especially on 20M.  The tuner is 
apparently ignoring some of the signals on the AUXBUS line.  I put a 
scope on that line.  I can see, some of the time, the amplifier 
responding to the signal with a "clunk" as the tuner relays adjust to 
the new segment.  The rest of the time, I see the signal, but no 
response from the amp.  If you attempt to transmit when the signal is 
ignored, you get chattering relays followed by "ATU Retune Complete" on 
the amp display.  I took a photo of the signal trace and sent it to 
Support yesterday.  They haven't gotten back to me yet.

Things to check

Could be bad aux cable. Is it from Elecraft?

Do you have anything else connected to aux?

Are you sure connectors are fully engaged?

Hi Joe,

Let us know if you have any question about the SideKar Plus.

It was specifically made to enhance your RTTY, PSK, and CW experience when
using the KX2 or KX3.

Plus the messaging and logging features are great when portable.  I used
them extensively for my 5300+ NPOTA portable QSOs.

Howdy Gang.

Contemplating operating digital portable so am wondering if any Elecraft
folks are using the QRPworks SideKar Plus unit.

Comment, likes/dislikes are appreciated.

Any info most welcomed.

If HiSWR AUTOTUNE is enabled, this would be the expected behavior. 
However, ATU switching at the start of transmission sometimes happens 
even with it disabled.

Elecraft is working on the ATU firmware in relation to this issue. I 
noticed it some time ago. Even with the HiSWR AUTOTUNE turned off and 
AUXBUS frequency data from the K3, the ATU sometimes switches when 
transmission starts. I don't know quite what it sounds like on the other 
end, but I seem to get asked for repeats off when it happens. Although 
the K3 sends frequency data to the KPA1500 only once per second, that 
isn't the main problem, as the switching occurs even if tuning has 
stopped for longer than that.

Stay tuned.

This is exactly what happened to me. Very annoying. My KPA is in the shop repairing the blown final and I hope they can address this issue as well. My thinking is that if a tuned solution for a given frequency is already known then it should be set as soon as the radio QSYs there.

My KPA1500 tuner responds to CAT commands from my Flex radio and doesn?t miss a beat. 

So CAT seems to be fine but AUX connection is ?intermittent??

Ever since I have owned my K3, I have noticed that most spots put the 
K3's receiver above the actual frequency of the spotted station.? 
Initially, I thought this might have to do with DX spots being rounded 
to the nearest 100 Hz, but then I realized that, if that were the case, 
X percent of spots should be high, X low, and Y (whatever percent) 
effectively right on.

I've checked the K3's calibration, and it appears to be right on at 10 
and 15 MHz, tuning in CW mode to WWV's carrier at my preset beat note.? 
One possibility that occurred to me is that perhaps the DX cluster 
convention is always to round up, rather than up or down.

Seems a little unlikely to me, but does anyone know the answer?? I'm 
perfectly happy to keep jogging the main tuning knob a bit on most 
spots, but thought I'd ask.

We're looking at this right now. It must have crept in? with a recent release.

I'll post here as soon as I have an update.

I use the SPOT feature on my K3S to zero beat the carrier on WWV.   This gets me to +/- 1Hz. If it is more I'm inclined to tweak the reference such that it is accurate.    

As to posting spots,  I usually post to the nearest 1 KHz.  Thus from experience, I have little confidence in the display accuracy of other radios.

N1MM+ Logger, maybe others, have a feature that is selectable on/off (defaults to on) that randomizes the actual frequency used to populate their bandmap from incoming spots. 

As another poster mentions, in a contest, DON?T ZEROBEAT if you haven?t got the absolute strongest signal. Much easier to be picked up if you?re 30-100 Hz off of zerobeat, preferably higher pitch. I likewise use the XIT. However, if you?re tuned off one way to have a higher pitch, the station you?re calling could be using the other sideband, and now you?re a lower pitch. Your signal good go unnoticed. 

Operating as a Rover in the GQP each year, it?s amazing how many folks call us over and over zerobeat, 10 deep. New county, wash, rinse, repeat. I can see stations even a KHz away on the pan, out of the passband, calling me. They?ll get worked before the others spread out. Ground Hog Day.

And in a pileup the RX bandwidth is narrower.  At 50 Hz BW any 12 to 15 Hz away aren't heard.  Yes a higher frequency tone will appear louder.

Not really, and for several reasons. First, many skilled CW ops use a 
fairly wide bandwidth in a pileup so that they hear off-frequency 
callers. Second, even at the 200 Hz IF setting and 250Hz roofing filter 
I routinely use, the -6dB bandwidth is on the order of 250 Hz (it's 
generally well known that the 250 Hz filter is closer to 350 Hz). Given 
that 6 dB is roughly one S-unit, the practical RX bandwidth is more like 
250 Hz for reasonably strong signals, and reasonably strong signals 
farther off frequency are going to be heard. Third, in a pileup, the 
WORST place to be is zero-beat, because that's where most stations call, 
and everyone's TX blends into a big mush.

You DO want to zero-beat the CQer if you're weak and there are no other 
callers.

Most of my CW work is on nets.?? Otherwise, pse QNZ.?? If one is not on 
frequency, one is not heard.

If you're talking about the spots in the bandmap, the difference is 
probably your BFO pitch offset.
Switch sidebands, and you'll see the mark on the other side of the 
spotted station.

The others are right about not zero-beating. It's a curse in a contest. 
I call them 'cluster clickers'.

Perhaps what we are seeing here is the cumulative error of the transceivers in the chain. 

The DX tunes the rig to 14023 and calls CQ, but their transceiver is just a bit off frequency for one reason or another, so they are really on 14022.95.  

The spotting station?s transceiver is also a bit off frequency, so when the DX is tuned in, the spotter?s rig shows 14023.1 - and that?s what gets spotted if the frequency is acquired as data from the rig.  If the spot is generated by keyboard, then more errors are possible. 

So when you click the spot, you go to 14023.1 and are .15 off the DX frequency +\- whatever variable your rig might introduce. 

I don?t have the expectation that when in click on a spot that I will be exactly on the DX frequency.  I just like to land in the general neighborhood!

I wondered if someone (Mike W5JR) would mention the N1MM feature to
randomise spots frequencies on the Bandmap so that you DONT call on Zero
beat.

I use this feature and it works of course but you often wonder if this is
the best tactic especially if you feel you are not getting a response
within a couple of calls.

Given that some ops will be listening with a very narrow filter at least
some of the time, you may not be in their filter passband and so not heard
if calling off frequency.

Thoughts anyone?

Mark,

The RIT SW# is SWT47;

There is also a RIT command, RT

RT (RIT Control; GET/SET)
SET/RSP format: RTn; where n is 0 (RIT OFF) or 1 (RIT ON). RIT is 
disabled in QRQ CW mode.

There are a few others, see page 23 of the programmer's manual Vers. G3.

CORRECTION

The RIT switch is

I'm not sure what is gained by checking REF CAL against /all /WWV 
frequencies.? The manual suggests using the highest frequency on which 
WWV can be copied ... 10 or 15 MHz (10,000 watts), or (better) 20 MHz 
(2500 watts) if propagation is right.

Performing the REF CAL calibration against WWV's main carrier is quick 
and easy but requires a quiet room and good ears.? Drake alumni are used 
to the procedure having had to flat-line the "chirps" when zero-beating 
receiver against transmitter, especially on SSB signals.? As a reminder 
for newer ops, the transceiver should be on for at least 15 minutes 
(according to the manual) before doing the calibration.? I personally 
wait 30 minutes or more, depending on room temperature.

One night, a few days after FD, another K3 owner told me I was a couple 
hundred cycles off our net frequency (CW).? Having just gotten the rig 
back from Elecraft for updates (s.n. 21), I replied, "on your end, pal, 
can't be on mine".? I then checked for myself and discovered I was 
indeed several hundred cycles off WWV.? Since then, I check it every few 
months.? Components do age, you know.? Especially 12 year-old ones.

Kent? K9ZTV

I tried it, but I found it spread out the spots way too much, and could 
find a way to control the spread. Now I just offset the XIT 30 Hz or so.

Another possibility is all those SDR's sitting in unheated sheds sending 
RBN spots. That, of course, would lead to more or less random frequency 
errors.

Hi,

if you are using the SPOT function on K3 then be careful...
It does not work properly when you have the NTCH in use.
I do not know why but I noticed it several times that SPOT is failing with
NTCH ON.
Also it does not work for 100% when the receiving signal is weak...

A better method is to tune the receiver to the carrier frequency of the 
highest WWV frequency you can hear. Then put the receiver in SSB mode 
and look at the line out audio with a soundcard-based spectrum analyzer 
such as Spectrum Lab (https://www.qsl.net/dl4yhf/spectra1.html). Check 
to see if the 500 Hz and 600 Hz tones are correct. If not, adjust the 
REF CAL to make them right. Be sure to check on both USB and LSB; you 
may have to split the (usually very small) difference between the two 
sideband responses.

I do the same but use CW mode and reverse-CW. Easier to see difference and more precise adjustments. Dennis K4THE

This is a good method.?? See my article in ARRL QST, September 2015, 
TRANSMIT AND RECEIVE ON FREQUENCY.?? I suggest using software for PSK-31 
as the AFC will always lock onto the audio frequency and then show the 
actual frequency.? It is usually good for 1 Hz resolution.

Hi, all concerned:

With much help from many sources, for which I am thankful, I now have an
operational remote control system: K3/0 to remoterig 1258 in Cincinnati OH
to 'net to remoterig 1258 to K3S to antenna in Dayton OH.

The remote system has worked fine so far. I've had a number of CW and SSB
Q's, mostly on 40M.

I tried to program the front-panel MESSAGE memories per the K3S user manual
instructions, and was unsuccessful, which got me to wondering if others have
found inoperative functions.

I look forward to any and all responses, tks.

Brgds,
Dave, N3HE

You can send from the message memories pre-programmed into the remote 
K3, however you cannot program them remotely as you found.? I'm not sure 
about AD REC and AF PLAY, haven't tried them.? I don't believe you can 
program macros into switches remotely either, but again, haven't tried 
although I believe if the remote K3 is programmed [e.g. PF1=SPKR+PH], 
then I think you can activate it from your control K3/0.? After thinking 
thru how the K3/0-K3 interface works, these few functions make sense.

Message-ID: <002f01d4cb0b$6fcafdc0$4f60f940$@videotron.ca>

Hi,

There is a new release of Win4K3Suite.  Version 1.948 includes a number of
enhancements to the Spectrum scopes pertaining to peak detection resulting
in continuous display down sampling instead of the discrete steps in the
past.  This new release will also display the SWR after the first transmit.
(Note this is not currently available for SSB modes).
You can see the complete list of changes here:
https://va2fsq.com/documentation/
Win4K3Suite is a comprehensive control program for the K3/S, KX3, and KX2
supporting the KPA500, KPA1500 and KAT500.  It has 6 built in virtual radios
allowing trouble free port sharing as well as a built in HRD Logbook server.

Dave,

I know this works with the DVK voice memories, because I have done exactly
that. However, you will not be able to program CW/digital message memories
as easily, because they have to be recorded using the K3's internal CW
keyer (from the paddle jack). You can't record them from the straight key
jack, which is the CW keying connection that the RRC uses.

There is an alternative way to program these messages using the K3 Utility,
but I don't know whether you can safely use the K3 Utility over a remote
connection for this purpose.

If you use radio control/logging software that has the capability to use
the Winkeyer in the RRC, that software probably has its own CW message
memories that you can use instead of the K3's message memories (for
example, the function key messages in N1MM+).

For similar reasons, the CW-to-Data feature (sending RTTY or PSK using a CW
paddle) is not likely to be possible using a remote connection.

Rich VE3KI

Hi,

I am setting up for the CQ160 SSB contest and notice a strange behaviour with my K3. Opening the second RX there are no received signals. Second RX/Diversity works well in CW, but not in SSB. If I go into settings and filter settings, then press SUB the receiver starts. It continues working until I touch the filter adjustments or any of the other rotary encoders SHIFT, WIDTH, SPEED/MIC or CMP/PWR. 

I can remember I changed any settings relating to filters and second RX in a long time.

Any ideas out there?

Subject: [Elecraft] setting up DX-Lab for my kx3
Message-ID: <433904227.163774.1550893154340@connect.xfinity.com>

Hello,

I want to set-up DX-Lab for two radios, namely my Yaesu FT-950 and the KX3.

No problem with DX-Lab controlling the FT-950.  

(I do know that the KX3 has communicated with the KX3-Utility program today, so that tells me the USB connection works.)

But DX-Lab and the KX3 are not talking to each other, so here are my settings for the KX3 in DX-Lab:

Port....7

Baud....38400

Word....8

Parity....N

Stop....1

DTR....N

RTS....Y 

Also, in Device-Manager, flow-control is 'None'.

Am I ok here or should I be looking elsewhere?

TIA for any reply.

In the past few months, my P3 has begun to intermittently forget its 
SPAN and CENTER values (it is always in fixed mode).

It doesn't seem to be related to any changes in firmware in either my K3 
or P3, which I haven't done in some time.

I use the DXLAB software, in case that could have something to do with it.

Before I bother Elecraft, has anyone had a similar isssue?

Ok I'm betting it's the same through your headset (if you use one) and 
you have the volume controls for both the main and sub "matched".  So 
here is my best guess:

Check the NR and ATT are set the same for both the Main and Sub 
receivers.  Sounds like you have NR or ATT set ON for the Main and NOT 
the sub receiver.  If these settings are not the same the audio will be 
noticeably different on the main and sub receivers.  BSET is your 
friend.  Not sure if NR and ATT settings translate to Line Out audio 
levels... but maybe.

Dear Nate,
I had the same some month ago and it costs me EEINIT and new Firmware without success. Than I had the idea to check RF Gain. The RF knob of Main and sub were on different positions.

If these settings are not the same the audio will be noticeably different on the main and sub receivers.  BSET is your friend.  Not sure if NR and ATT settings translate to Line Out audio levels... but maybe.

One thing that I don't see mentioned is that the gain 
settings for the for the crystal filters in the two 
receivers may be resulting in somewhat different gains over 
the signal path in the main and Sub Rcvrs. I notice some 
differences between the main and sub rcvrs which varies if I 
change the gain settings on the filter being used. 73, Ken K3IU

Yes I did check the antenna settings for SUB RX. It seems to be a problem that appeared with an upgrade or by time. I can?t remember I did anything in settings to create this behaviour. As I am able to get it working again by going into filter settings and press SUB and then the RX dies when I do something with the radio (either directly or via CAT) it seems to be software related rather than hardware.

I?ll pass this on to support, but if someone has more ideas I am all ears as I really need my second RX in the contest this weekend.

Message-ID: <CE424025-CD31-4348-8DBD-99410541E70B@fastnet.co.uk>

Hello All,

I have recently acquired an early K3 which needs tidying and checking over.  So far all appears to be OK except for the KPA3 which gives no RF output but the rig draws 14 Amps regardless of the power setting.  The LPA is working fine with up to 12 W RF out and a max current draw of 4 W.

Visual checking of the KPA3 board reveals nothing amiss but also shows considerable component differences compared to the only schematic I could find on the Elecraft website - the Rev C version.

If any of you early adopters have a .PDF schematic for the KPA3 Rev B, I would be most grateful for an electronic copy.

73, Ted G7BQM  (with quite a lot of Elecraft stuff!)

Hi, 

Thanks for the help on this!

I did find the problem, it was a setting where the filters for the sub RX wasn?t turned on for the corresponding filter width of the main RX. I remember some time ago my remote connection went crazy and the radio entered the settings menu. I also found a could of other settings being off, so all these have been returned to where I need them and second RX is now OK again.

My K3 seems to be all set up for RTTY ? DATA Mode, AFSK A selected, I am using Line in on the rear panel (selected in the MENU), I use MMTTY/N1MM, and I use a microKeyer III.  All appears well except that I need to switch the K3 into USB mode to actually transmit RTTY.  If I have the K3 set to DATA mode, the PTT is working (K3 TX light comes on) but the K3 is not transmitting tones.  

This must be something simple I am overlooking. Any ideas for what to check?

Many thanks for your reply Peter.

The Rev C  schematics are the ones on the current Elecraft website, which I have.  I was suspicious of the pins which are the originals, but they look OK and Deoxit has not cured the problem.  Yesterday my order of some ribbon cables arrived, and I was able to run the KPA3 outside the chassis upside down.  On demanding more than 12 W power there was a rapid smell of hot electronics but no smoke.  The 2 x 51 ohm 3 W grey resistors were hot enough to cause a minor burn!  I have still to determine where the rest of the power is going - the transistors?

If you have any details of the bias setting method, that would be really helpful.  I have not been able to find any information on this on the internet.

Thanks for the good luck - I need it.

73, Ted G7BQM

Good catch, Scott.

Indeed, I did not have the ATT engaged on the Sub receiver!  However,
even though it makes less noisy on the low bands, the audio levels still
vary by about 6 dB when both are switched into a dummy load.

It seems as though when playing with AGC THR that the lowest value of
002 results in the levels being closer with live signals off the air.
As that value is raised the Sub receiver (right channel in Audacity)
raises level considerably faster.

Ed,
     Your basic set up is correct, DATA mode - AFSK. Do use line in/out. 
However, there is no need to to switch into USB. FLDIGI will take care 
of everything from here. I use VOX to turn on the transmitter vice 
computer control and this just works FB. And yes, K3NDM will be in NAQP 
this weekend.

Hello,

Please disregard my yesterday's email. 

I fired up the system today and everything works, which is a surprise since no changes were made.

I have no explanation for this right now but will attempt to see if the port was shut-off; Dave-AA6YQ cautions about that from time to time. I thought I had done that operation a long time ago but maybe all the MS-updates messed that up. 

Sorry to take up the bandwidth.

Ed,

It would seem that N1MM+ and MMTTY are fighting for the RTTY operation.
Normal RTTY operation is on lower sideband, and that is the default of 
AFSK A.  If it is set to upper sideband, the ALT button will switch 
sidebands for you.

Make certain that you do not have "reverse" or "invert" or anything that 
would change the sideband for AFSK A mode set in either MMTTY or N1MM+.

73,
Don W3FPR

I?m assembling a KRX3 second receiver for my K3.  One of the filters I?m
installing is a KFL3C-400.  When I ordered it, the order form said it was an
8-pole filter.  I purposely only ordered 8-pole filters.  It was my
understanding that 8-pole filters have no offsets to worry about.  Why,
then, does the KFL3C-400 have an offset (-0.79) listed on the filter when
the others do not?  I?m confused.  Can someone clarify this for me?  73 de

Did you select: MENU:MIC SEL = Line IN and set the Mic Gain
(Line In) level for four bars of ALC *AFTER* switching to AFSK A
(DATA)?

The K3/K3S Mic Gain control is overloaded (used for both mic
gain and Line In) and defaults to Mic Gain = 0 when initially
selecting data modes.

Hello-
Purchased a KX3 in late December 2018, unfortunately ham radio isn?t for me and I missed my return window.

For sale:

Kx3 with built in tuner and bypass filters all factory installed.

Ax-1 multiband whip antenna and bipod stand

Dx engineering power supply for the kx3.

Everything works perfectly, barely used and never used outside.

$1400 shipped

Happy to send photos.

Thanks for looking.

Alex

Is your filter in a metal can. Eight pole filters used to be in a can. Five pole filters were exposed parts. If the later, count the crystal cans. Should be 5, 6, or 8.

Bill, 

Thanks for your response.  This filter, unlike the others, is exposed and there are six crystal cans.  Does this mean it?s a five-pole?  I was sure I ordered an eight-pole filter?  When I do a search on the KFL3C-400 everything I see indicates it?s an eight-pole filter.  Are there two types of KFL3C-400 filters?  As you can see I?m still confused.

Carl,
It is a six pole filter. 
It sounds like you got the 200 Hz filter in lieu of a 400 Hz filter.
I think a call to Elecraft Sales is in order.

Good advice, Mark.  I?ll do that on Monday.  I?m happy to see that I?m not the only one confused by this. I really only want to use eight-pole filters in both main and sub receivers.  73 de Carl

Subject: [Elecraft] P3TXMON Advice
Message-ID: <20190223230916.sozs422zz6tgijif@radio.lan>

I'm contemplating adding a P3 to my K3s and the P3TXMON option seems a
worthwhile addition. I am trying to figure out which directional
coupler to select but can't find much if any information between the
DCHF-200 and DCHF-2000. So I don't have any data upon which to base
the decision. At the current time I have a K3s/10 and a KXPA100 amp
and so the 200W coupler would be fine but maybe there's a higher power
amp in my future, don't know. Seems like there must be some
performance aspect that the DCHF-200 has that's superior to the
DCHF-2000 or else there would be no reason for the '200s existence.

If anyone can give a little more information I would very much
appreciate it.

I have noticed that also. Luckily I remember which filters are 8 pole but
the website really should specify.

N8VZ may also try contacting Inrad. Scott may answer on weekends?

I have the 2000 Watt version and it is entirely satisfactory for me even
when operating at 100 Watts or slightly less.

Eric -

I know a number of KPA1500s have been returned to you with one of the 
output transistors dead. Is there common source for the problem that 
the rest of us can try and avoid?

Steve,

The 200 watt coupler will give more resolution at lower powers.
In other words, the 2000 watt coupler covers the scale from 0 to 2000 
watts, and 100 watts is only 1/20th of the way up the scale.  With the 
200 watt coupler, 100 watts is the halfway point.

73,
Don W3FPR

I too have the 2000 watt version and I get very usable results even at QRP power levels out of the K3S.

I'm avoiding it now! My KPA1500 died for the second time since it 
arrived last September.? I contacted service last Thursday and, per 
request,? sent them my configuration information. Nothing has been heard 
since.

Now my "old" KPA500 and KPA500 are back in line and working fine! That 
appears to be a good fix as they've never let me down.

My KPA500 displays the temperature in degrees Centigrade.?? Just 
remember, small numbers cooler, larger numbers hotter.? Normal room temp 
is about 23 to 25 degrees C.? The fan switches on at 50, steps up at 55, 
steps up at 60 and steps up at 65.........as I recall.? The book says 
maximum temperature must be less than 90 degrees C.?? To me, that is all 
one needs to know about Centigrade.

Just for the record:

23 C = 73.4F

25 C? = 77 F

50 C =? 122F

55 C = 131F

60 C = 140F

65 C = 149F

90 C = 194F

Otherwise, [C x 9/5] + 32 = F degrees

Wow! I apologize for the problem.

I believe we reviewed your config file and fault log on Friday and we are authorizing return of the RF deck at our cost and will send you prepaid UPS shipping label on Monday. I will stay on top of this to make sure it proceeds quickly.

I will take a closer look at the file myself and will follow up with you later this weekend via direct email to go over what I find and also review the operating conditions etc that led up to the failure. In any case, we will dig into this until we fully understand what caused the problem and resolve it for you.

Regards,
Eric

Good Evening,

 ?? Winter had been mild, now that's only a memory.? It has snowed every 
day for two weeks.? The sun was also experiencing mild weather but now 
it has a hole shooting ions off into space.? The stream is turning our 
way due Tuesday and Wednesday of next week. After the aurora settles 
down there should be decent propagation for a while.? Maybe next weekend 
the band will be noisy with static but filled with distant signals.

Please join us tomorrow on:

14050 kHz at 2200z Sunday? (2 PM PST Sunday)
 ?7047 kHz at 0000z Monday? (4 PM PST Sunday)

73,

 ?? Kevin. KD5ONS



It was a cord of maple, cut and split
And piled--and measured, four by four by eight.
And not another like it could I see.
No runner tracks in this year's snow looped near it.
And it was older sure than this year's cutting,
Or even last year's or the year's before.
The wood was grey and the bark warping off it
And the pile somewhat sunken. Clematis
Had wound strings round and round it like a bundle.
What held it though on one side was a tree
Still growing, and on one a stake and prop,
These latter about to fall. I thought that only
Someone who lived in turning to fresh tasks
Could so forget his handiwork on which
He spent himself, the labour of his axe,
And leave it there far from a useful fireplace
To warm the frozen swamp as best it could
With the slow smokeless burning of decay.

Technically, ?Celsius? rather then centigrade!

We are more or less used to Deg C in Canada after about 40 years of using it.  Deg F are still sometimes used though.  Older folks understand both while kids have no idea what a yard or a pound is!

Subject: [Elecraft] Orion II and P3
Message-ID: <CA+03d8gxefUEMJWn=Y3S+358ukfUkVADRv+=tEM-6gecjV9kQw@mail.gmail.com>

I have recently acquired an Orion II and I am looking to hook it up to my
P3.

I have got the details from VE7TK's website as regards the mods needed to
the Orion II and it looks fairly straightforward.

Before I go down that road, I wondered if anyone else is using or has used
that set up and if there are any hints/tips I should know about.

In answer to the unasked question, why have I bought an old Orion II.
Because I have ! I like playing with different rigs although the K3 and
TS990 are the two definite keepers.

I await any responses with interest.

I think Elecraft altered their filter array recently ( maybe 1-2 years) and maybe the order page hasn?t caught up. I believe they discontinued some and added some 6-pole filters. I think that is what you have.

After switching on the AFSK TX filter in the CONFIG menu, I find that the filter essentially blocks all the soundcard audio from being transmitted by the K3, so that I have no output with the filter switched on. Line In gain settings are correct per recent suggestions by Joe, W4TV, and all other K3 settings are proper. When I turn off the AFSK TX filter, the K3 returns to operating normally in AFSK Data mode, with full power output.  I can leave the filter out but am wondering why it is blocking the audio? I am using MMTTY, so perhaps it is a setup issue within that program?

The K3 AFSK TX filter is a very tight filter around the two RTTY tones,
which blocks all other frequencies in the passband.  Are you intending to
transmit something other than RTTY when the blocking occurs?

Ed,

I am not certain what you are referring to as the "AFSK TX filter".
You must enable the 2.7 or 2.8kHz filter for all DATA modes.

You can enable any filters for receive in any mode, but you cannot use 
narrow filters for transmit.

The AFSK TX filter is a narrow audio filter that allows only the
defined mark and space tones to pass.  Check the PITCH setting in
AFSK A and make sure it matches the MARK setting in MMTTY (e.g.,
2125, 1275, 915Hz).

 > I am using MMTTY, so perhaps it is a setup issue within that program?

As above a conflict between the K3 and MMTTY.

I just connected my new KXPA100 to my KX3 via a home-brew KX3-KXPA100 Adapter Cable.
Everything works just fine if I have the 3dB attenuator switch set to IN.
I fI set it to OUT/AUTO as described in the manual I end up overdriving the amp, meaning the power out is much higher

All the other functions work just fine.
Anyone have any ideas?

Just for correctness, it's not 2 African countries but Liberia and Myanmar.
I can only guess that there is no economic incentive for the US to switch.

Message-ID: <CAP4v5qw+60Qy+aTVaUJRbWu2USK5pB=k3pqo-7r+tT3mnipFTA@mail.gmail.com>

I am having problems getting the PX3 to work with a thumb drive for
screenshot captures. I had one smaller thumb drive (32MB?) that the PX3
would mount but wouldn't save screenshots too. So I figured maybe the thumb
drive was bad and bought another one. This one locks up the PX3 or causes
the px3 to run extremely slow. This is a brand new thumb drive 128 GB size.
Is it the size that is choking the px3? Should I buy a smaller one, is
there a recommended size? The PX3 manual states nothing about what the
thumb drive requirements are to get it to work.
Thanks, 73's Mike AB7RU

Good Evening,

 ?? Both bands had a steady hiss with rapid QSB between a wow and a 
flutter.? Signals were weaker than last week.? Weather reports were 
attention grabbing.? I kept hearing the word blizzard.? 50 mph with 
heavy snow is pretty intense.? When lightning and thunder accompany it 
you've really got a storm.? That got me thinking about autonomous snow 
blowers until I thought about the neighbors' pets.? A homing beacon for 
the lonely shoveler would be more useful.

And both that morning equally lay
In leaves no step had trodden black.
Oh, I kept the first for another day!
Yet knowing how way leads on to way,
I doubted if I should ever come back.

I shall be telling this with a sigh
Somewhere ages and ages hence:
Two roads diverged in a wood, and I -
I took the one less traveled by,
And that has made all the difference.

	working
Message-ID: <f8718cead70fed8d95026dce36b5e797@f5iyj.com>

Hello, 

I have read previous posts from this reflector and instructions from
different sources without being able to have my K3 connected to SPE
amplifier with CAT. 

I have upgraded my K3 (S.N.#4004) with the new KIO3B so I connected my
computer (running Windows 10) with the USB cable and the P3 with the
CBLP3Y as presented on page 18 of the K3S Owner Manual. Everything is
working fine for months. 

I recently got an Expert SPE 1.3K-FA I am trying to connect to that CAT
chain. I read on this reflector I needed to connect a RS232 Y cable
plugged to the CBLP3Y, the PC DB-9 port on the P3 and the CAT port on
the SPE. This made the connection between the K3 and the P3 not
functionning, missing the green and red bars from the 2 K3 receivers on
the P3. 

Then I made another RS323 Y cable, using only TXD to RXD on the SPE
side. It was better but the USB port on the PC USB link stopped
functioning. 

On the K3, RS232 is configured as 'USB' and on the P3 the baud rate is
'38500'. I used on the SPE both 'Elecraft' and 'Kenwood' CAT settings
without any success but if I only connect the K3 and the SPE using the
CBLP3Y cable + DB adaptor on the SPE, it works.  

So does someone have experience with this configuration and can let me
know how it should be connected to have it working? 

Thank you   

73,

Ciao Philippe,

the CAT speed in the P3 must be 9600, Expert can't go faster, so, CAT 
settings are Kenwood-9600.
On teh P3 use the rs232 port DB9, for PC and SPE.
Here is a link to a page on my site where a working connection is 
explained.
Explanation is in italian, but schemas are available also in english.

http://www.iw2noy.it/index.php?id=87

Here is the link for the schema with elnlgish description:

https://drive.google.com/open?id=1aIHjl5KYsh6rPvRfjyUM2SAjrtoFDtn9

I have K3s (so KIO3B installaed), P3 and Expert 1KFA.
Everything is working, with connection at 38400 between K3s and P3, and 
connection at 9600 between PC-P3-EXPERT.

Let me know if you question, i am available also in PVT.

Best 73's de IW2NOY

Message-ID: <1551120901019-0.post@n2.nabble.com>

At first i suspected my Solar power system which was installed a year ago,
but now I  plugged my K3 S/N 7317 directly into my 25A switching DC power
supply, and when key down, 100W in CW, on the internal K3 Power Meter i see
a voltage drop from 13.6 to 12.0VDC.  My power cord is a 6',  10ga stranded
copper wire pair with Andersen Power Pole connectors.  I have tried three
separate power cords, all 10ga with power pole connectors, but with no
change in the voltage drop scenario.  If anyone has suggestions of where the
problem  lies, I am all ears. Obviously, when operating SSB the drop is
present but not as severe.  What am i dealing with?  Better yet, how do i
fix it?  Thanks in advance.
Cheers,

Hi Mike, 

What are your voltage readings at the power supply end of your 
six foot power cords? 


None of my K3s do behave the way you describe.

I have a K3 that behaves similarly to what Mike described. I switched from an Astron 25 amp (15 years or more old) power supply to a switching power supply. Problem solved. One would think the problem was my Astron power supply, but I don?t see any such power drop when I use my Astron with other 100 watt rigs. Very strange.

I had a similar problem. I checked the key-down voltage at my power supply, and was surprised to see that it was low (I don't recall the exact voltage).I'm using an Astron linear power supply. I replaced the voltage regulator in the power supply, and the problem was solved.73,Don Sayler W7OXRSent via my Mobile

Jimmy,

Astron power supplies have a nasty habit of having loose wiring 
terminals.  They use only pressure to hold the ring terminals on the 
inside to the terminal bolts.
If you can detect even a slight rotation of the bolt when tightening 
terminals on the outside, remove the covers and tighten those bolts from 
the inside.

The other problem is improperly assembled APP connectors.  If you look 
straight into the end of the connector, if you can see the tip of 2 
blades in either side, give the contact blade an extra push from the 
wire side until the contact blade locks over the locking tab.
That is also a cause of APP connectors which tend to pull out with very 
little tension.

73,

I suspect the problem is the power supply and Don has some good
suggestions. I am not sure what the actual K3 power requirements are.
FWIW, Astron's are rated for ICS, if you really want 25 amps continuous
you need a 35 amp linear power supply.

Poor regulation is a common failure mode with Astron linear power 
supplies. The problem is equally likely to be either in the power supply 
section or in the regulator section. 


There's an excellent troubleshooting and repair procedure here:

There are two adjustments in my Astron 35A supply.  One on the board, 
adjusts the voltage.  Another on the meter, calibrates the meter.  I 
found my output on the terminals was almost a volt low even though the 
meter read full.

I adjusted the pot on the board and then calibrated the meter using two 
different VOMs.  Now, all is well.  Trust but verify...

John and all,

A 25 amp power supply should adequately power the K3 at 100 watts - but 
check the K3 specifications if contemplating 100 watts for DATA modes. 
The K3 is rated for ICAS and not for continuous duty.

Also keep in mind that the K3 is a bit different than other amateur 
transceivers in the way it controls power.  The K3 attempts to maintain 
the power in watts rather than just the drive level when you set the 
power knob at 100 watts.
That means if the voltage drops during transmit, the K3 will increase 
the drive and maintain 100 watts.  It takes more current to produce 100 
watts at 11 volts than it does at 13.8 volts.

73,
Don W3FPR

Just for*correctness*, it's not 2 African countries but Liberia and Myanmar.

OK, Liberia is in Africa alright;  BUT, Myanmar is in Asia

Hi all,

I am sorry, Eric, but I want add another comment to this. I was raised and
educated in Norway which I believe is one of the original signatories to the
metric system. I have come to deal with the non-metric units common here
since I moved here and I don't find it a big problem.

But I have to correct what I believe is a misconception (that the US hasn't
adopted the metric system). NIST, the federal organization responsible for
metrology in the USA is *totally* committed to the SI system which is the
current formal definition of the "metric" system. I think what sets the US
apart from most other nations is that SI units are not mandatory in
commerce. The US units of ounces, gallons, Fahrenheit, inches, feet and
miles are defined by NIST as derivatives of their SI base units, and are
obviously allowed in commerce.

So, should the US commit itself to mandate the use of SI units for all
commerce and signage? I don't know. It would be costly for sure.

Well we first authorized use of the metric system in 1866, we are working
on getting around to it. Don't rush us!

Message-ID: <CAK+fsRUU-9xbeU2hiefQwD5D09_zY89bs60ve5hDDUwpGu_vPA@mail.gmail.com>

I've found instances of regulation failures caused
by loose hardware.  In particular the nuts atop the
filter caps that hold the regulator PC board loosen
and simply tightening then will cure the issue.  This
appears to be caused by compression of the PC board
material ?"cold flow" to some readers.

There are several other common failures of this series
of PS's, but this one is perhaps the most prevalent.

While you have the cover off, check for paint under the
lug on the green power cord wire ?

I've given up on Astron despite the fact that many people say they never 
have troubles.? Apparently, Astron does not have a supplier for inside 
star washers for screw/bolt connectors, I've found almost crumbly, 
crystallized cold solder joints on the point-to-point wiring terminals 
[in one case, it wasn't soldered at all], and often the case is not 
bonded well [or at all] due to paint and/or no star washers.? These are 
all basic steps in quality electronic construction, there's just no 
excuse for it.

Message-ID: <201902252256.x1PMumv1023457@mail42c28.carrierzone.com>

Larry,

I have the same combination (KX3 + KXPA100) and my KX3 drives the amp 
fully with output of 5 to 7w.  Takes more drive on 6m.  Each 
band  takes a different drive level.  It seems to me that does not 
track between bands.  I have to manually change the drive level.

But then I am not controlling the KXPA100 with the control line and 
only using PTT.  When mobile I use the RJ45 connection.
Most of the time my KX3 is on either 6m or 2m.  I use my K3 for HF or 
with transverters for VHF+.

I have used the 3-dB attenuator on occasion when I want to drive very 
low (getting 11w output for driving my 6m 1000w amp).  The KX3 or 
K3/10 only give me 8w max on 6m so need the KXPA100 as a driver.

I just connected my new KXPA100 to my KX3 via a home-brew KX3-KXPA100 
Adapter Cable.
Everything works just fine if I have the 3dB attenuator switch set to IN.
I fI set it to OUT/AUTO as described in the manual I end up 
overdriving the amp, meaning the power out is much higher
than set on the KX3.
All the other functions work just fine.
Anyone have any ideas?

Hi again,

Hopefully Eric will find it in his heart to let this thread continue.

Yes, we are. Booze and wine are now sold by the liter. Curiously beer is
generally not. In my opinion gas stations should be the next in line to
convert. I am sure modern pumps could easily be reprogrammed to display
liters instead of gallons. To the uneducated the price per liter would look
like  a bargain. Wow, less than a dollar! I don't think super markets would
encounter a huge cost converting from lbs to kilos either. Probably the road
signage would be the biggest cost problem.

For what it?s worth, metric units outside of the US are often spelled differently.  For example, ?litre? rather than the US-spelt ?liter?, or ?kilometre? rather than the US term ?kilometer?.  

A ?meter? is a device on an instrument panel!  This is likely a UK or European holdover.  

Similarly, in Canada, when talking about a ?center? (US), we write it as ?centre?.

A ?centre? is a place or an institution, for example a community centre, or a university research centre.  ?Center? means the middle of something, like the center of a photograph or the center of a line.

Just my two cents on this off-topic but interesting discussion!

Folks - Let's end this thread at this time. Its already past the OT posting limit.

For interested readers, just search the nabble Elecraft list archive on 'metric' 
and you will find a wealth of past postings on it.

For the record - due to my engineering profession, I'm immersed in the metric 
world daily, regardless of where I am living. :-)

I prefer the SFF (Stone, Furling, Fortnight) system that was used in
engineering back in the Dark Ages before Elecraft invented good
solid-state ham equipment.   :)

Center and Centre are interchangeable. They mean the same. Although Canadian
I use the American center, liter and kilometer; to me it makes sense. Spell
it like it sounds. In Canada we still buy lumber 2 x 4 in 8 ft lengths and
sheets 4 x 8. We need two set of wrenches Imperial and Metric. Should have
stayed with US units as America is our largest trading partner.

-----Original Message-----

For what it's worth, metric units outside of the US are often spelled
differently.  For example, "litre" rather than the US-spelt "liter", or
"kilometre" rather than the US term "kilometer".  

A "meter" is a device on an instrument panel!  This is likely a UK or
European holdover.  

Similarly, in Canada, when talking about a "center" (US), we write it as
"centre".

A "centre" is a place or an institution, for example a community centre, or
a university research centre.  "Center" means the middle of something, like
the center of a photograph or the center of a line.

Just my two cents on this off-topic but interesting discussion!

Subject: [Elecraft] K-3 Power Output
Message-ID: <EE94A2A1-1AB2-4AD0-8F5B-3AE0687F06AA@law.du.edu>

 I had a similar, if not worse, problem during the CW DX contest a week ago.  On Day 1 everything worked perfectly, including 15 meters.  On Day 2 everything except 15 meters worked perfectly.  On that band the KPA1500 would show a full-scale over-range power output and then shut itself down.  The SWR was never more than 1.2:1.  In standby mode everything was just right.  No problems.

Thinking the amp might have been at fault, I reloaded the firmware, to no effect.  Numerous tries with the power on the K3 set as low as 5 watts using the front panel control resulted in the same overdrive fault.  Same thing whether I keyed the rig, spoke into the mike, or pressed "tune."  The display on the KPA said 72 watts input when it faulted.  

No problem on any other band.  I noticed, after a while, that the power output indicator on the K3 display on key down would very briefly jump to near the top of its range and then quickly fold back to nearly zero, probably the result of the amp sending it a significant ALC voltage.  And again, same thing no matter where the K3 power control was set.  Shut the rigs off, went out for a walk and a ponder, came back, turned 'em on, and all was good again.

I would like not to have that happen during the SSB portion this coming weekend.  Any ideas, anyone?  Is it the K3 misbehaving?  The KPA sending the K3 the wrong status info?  The operator doing something wrong?  Hacking by contest competitors? (hardly necessary)

    One of the features I liked with the K-3/KPA-1500 combo was having power 
    setting in the K-3 remain at 100w for barefoot or amplifier STBY 
    position.? When the KPA-1500 was set to OPER, the power from the K-3 
    reverted to the low drive level, such as 32w.? Now it remains at one 
    power setting either way.? I can't figure out what caused that change.? 
    The cable between both units is secure in place and they are 
    communicating with each other.? As I tune the K-3 the KPA-1500 tuner 
    settings change normally.? Any idea why this changed?? -Jim

With the RS-35m Astron Linear PS I have issues with noise.  I purchased the 
PS because everyone around me swears that they are great.  Well, from my

That's interesting. About the only way I know that a linear supply can 
be noisy is if the regulator oscillates. That can easily happen. Most of 
them use emitter followers, which are often unstable driving a 
capacitive load. That's usually easy to fix by inserting a small 
inductance between the emitter of the transistor and the load. A few 
turns of the appropriate sized wire around a ferrite bead usually works.

K3s + KAT500 + 80m dipole

Using DATA mode on all bands, and have been ever since FT8 was invented.

This evening was my first look at working FT8 on 80 meters. The tuner is giving the radio a 1.0:1 match, and the waterfall is busy.

But there?s no decoding happening! I checked BND MAP in the CONFIG menu, and 3.5 is enabled.

Switched to 40 on the same antenna ? great gobs of decodes.

Back to 80 ? no decodes despite lots of signals in the waterfall and in my ears.

HOWEVER! If I switch to USB on 3.573, everything comes to normal life: waterfall AND decodes!

It gets weirder.

3.573 in DATA mode: I can transmit normally with normal ALC and power readings, but still nothing decodes.

3.573 in USB mode: I cannot transmit ? NO ALC or power readings. But the waterfall and Decodes are normal!

WHAT?

I?ve gone through all the WSJT-X preferences (settings) and can find nothing overlooked.

Ideas?

I have personally found several instances in power supplies I either own 
or have repaired where the green power wire lug is firmly attached by 
the bolt and nut.?? It however was nicely insulated by the paint!.???? 
Visual inspection is the best way to determine if an issue exists.? Do 
take time to remove the bolt and nut securing? the wire lug to the 
chassis.?? Clean the area to bright shining metal where the lug would 
come in contact with the chassis.? Then reattach the green wire and lug 
with the original nut and bolt.

I have a ~30-year old Astron 13.8 VDC 20-amp supply that I got when it was retired from a project at work.  I used it for low current applications for a few years, then it went to storage for about 5 years.

One of the two power transistors failed a few months ago and this took out some other components.  I had put it back into service in a 5-10 amp application.  I figure that the failure was likely just due to age and the fact that the supply had been in storage for a few years.

I replaced both of the power transistors, two blown diodes, the electrolytics, and a couple of ICs and other components, and the supply is running fine again.  Solid output at 10 amps load.

Given its age I am extremely happy with it.  The internal quality and components seemed good, but that may have been due to its design/manufacturing era.   Not to sound like some old codger, but perhaps designs aren?t as robust as they used to be.

I have and use the same configuration as you describe.?? Make sure both 
VFO A and VFO B are in the same mode.?? Be sure you are in DATA A 
mode.?? With DATA A mode it is a USB mode? as used for FT-8.

The right side of the display on the radio should show SPLIT just above 
the VFO B frequency, then TX with the arrow pointing down to B, and then 
DATA to the right.?? When you press and hold DATA MD it should show 
DATA??? A? in the VFO B area.

I trust you are running WSJT-X? V2.0 and have the application running as 
stand-a-lone.? Otherwise, no interfaces, no other applications, no 
logging programs or such which could be controlling the radio.

Mac?Gy?ver

Verb, informal (U.S.):  To make or repair (an object) in an improvised or inventive way, making use of whatever items are at hand....

* * *

Last weekend I had the good fortune to be on the Kern River, in the southern Sequoia range, with excellent hiking *and* RF conditions. I parked my car at the Hobo day-use area and proceed to hunt for a place called Miracle Hot Springs. On the web there are photos of the springs, but I never did find them. (Hints, anyone?)

Rather than continue the search, I decided to scramble up a very steep hillside for a better view. And/or a promising operating perch. Thanks to a very wet winter, the soil was just slightly moist and covered in well-rooted grass and moss in several lurid shades of green. It was optimally packed for a near-vertical ascent.

When I was a hundred or feet above the river gorge, I took in the view, ate lunch, then broke out the KX2 and the AX1 17/20 meter whip. I found both bands open for short skip. After I got tired of working 20-over-nine VE7s I decided to give the lower bands a listen.

Unfortunately, I had forgotten to bring the longer lengths of wire usually required to get onto 40 meters (20-25 feet). But I did have two 13' radial wires of the type supplied with the AX1. I left one of them connected to the rig's chassis ground, then threw the other into a nearby scrub pine and connected it to the rig's BNC jack using a BNC-to-binding-post adapter. The KX2's ATU gave it the ol' college try, but the SWR on 40 m was still in the 8 to 10:1 range due to the very short electrical length.

Here's where the "MacGyvering" part comes in. (Remember the TV show? Admittedly the stakes were not quite as high on this occasion. But still.) 

I reattached the loading coil portion of the AX1 to the KX2, without the whip. Then I stripped the tree-supported radial wire back a couple of inches, unscrewed the coil's aluminum cap a bit, and wrapped a turn of the radial around the cap. Retightening the cap made the assembly quite stable. 

I found that I could now get close to a 1:1 match on 30 meters with the 17 meter AX1 setting, and the same on 40 meters using the 20 meter setting. In effect, the AX1 became a very high-Q extension to the ATU's L-network. 

I had no trouble being heard on the low bands with this arrangement. Of course a pair of longer wires would have provided better results. But I'm sure MacGyver would make do with a guitar string if he'd forgotten his garrote.

I have two recent vintage Astron RS-35M units. They still use the exact 
same 723-based regulator circuit that they have used for thirty years or 
more, so the design hasn't changed. What **may** have changed is the 
build quality. I carefully inspected both of mine right after taking 
delivery. I made sure the green wire from the AC cord was securely 
bonded to the chassis and checked for obvious soldering problems. I also 
tied the negative output line to the chassis. They have both been 
running like trains 24-7 for the last three years or so. The only 
failures I've had (on both units) are the stupid internal meter lamps.

I bought a Rackmount 35amp Astron when I started working at my office (the office bought it).  We turned it on in 1993 and it is still on today.  I have a 50 amp at home that besides the crappy meter lights (they now are illuminated by LEDs!), runs like a champ.

Funny though, when I find a supply with the -VDC tied to chassis ground, I always pull it - some Astrons do and some don't.  All of our other linear supplies float (HP, QJE, Acopian).  Keeps ground loops at bay!

Filter caps bad?  AC on the DC supply side maybe?  A well made linear supply
does not make noise that has to be filtered otherwise.  All switching
supplies must be cleaned up because their design generates noise.

That's interesting. About the only way I know that a linear supply can be
noisy is if the regulator oscillates. That can easily happen. Most of them
use emitter followers, which are often unstable driving a capacitive load.
That's usually easy to fix by inserting a small inductance between the
emitter of the transistor and the load. A few turns of the appropriate sized
wire around a ferrite bead usually works.

I have had very good results with Astron, but I treat their products 
like MFJ's: When I get a new one, I always open it up, check that 
everything is tight, remove paint if needed, look at the soldering, etc. 
It is worth checking the tightness of the connections to the capacitors 
every 20 years or so.
The alternative to an Astron linear supply is usually a switcher, and I 
try to avoid switchers when possible for reasons of electrical noise and 
reliability.

YES!? This is a chronic problem with Astron supplies -- I've never seen 
one that didn't have this problem!? I first discovered and documented 
this issue almost 10 years ago.? In one supply, the two clam-shell 
sections of the chassis were also insulated from each other by paint!? 
This failure could easily cause instability!

Hi, all concerned:

The remote system is now installed and operating in the site pictured on my
QRZ page.
A 40M inverted-vee dipole at 120 ft apex height does play fairly well.
Better antennas and higher power are forthcoming <grin>
  
We had a long cold dark thunderstormy late session setting up the
SPECTRUM-provided ARRIS router properly.
SPECTRUM does not allow access to the router by WAN; only by LAN.
Next test will be to take a generic router to the site and see if we can set
it up for WAN access.

Tks for the responses to my question re inaccessible K3S functions.
I'll take that issue to the remoterig reflector.

Brgds,

My Astron 35M has been in use since ~1990.  I had to repair it after a
lightning strike that melted the tip of my 2M Ringo Ranger.  (The meter
lights have been gone so long, I forgot it had meter lights.)
A few years ago, I bought a new 35M and it was defective.  Returned it for a
2nd one that was also defective.  Went to the store and had them fire up a
3rd one that worked properly before I would leave the store with it. 
Guess they don't make them (QC) like they used to.

Larry, I'm curious why you'd use a homebrew cable instead of using the
Elecraft specific cable KXPACBL? It seems your cable is not performing some
function that the OEM cable provides so it makes it hard for someone to help
with your setup.

Subject: [Elecraft] K2 still a viable portable contest station?
Message-ID: <E4E0AC6E-7666-4A93-8957-1D35906C5E13@yahoo.com>

I?m heading down to Costa Rica tomorrow with a couple of friends to participate in the ARRL DX Phone contest.

Last year we took my KX3/PX3/KXPA100 combo and were pretty happy all round with it (the KXPA100 did seem to get upset periodically which always happened when I was off shift, resulting in me being rudely awakened?). 

The station has evolved a bit and in addition to my KX3/PX3/KXPA100 combo we will have a K3. One big attraction of the K3 is its RX antenna port so we can use a K9AY RX antenna.

While the K3 is unlikely to be a permanent fixture of my portable station going forward I?m curious about people?s perspective of the efficacy and viability of a K2/100 with the 160m/RX port option as a station in a contest (I have the DSP option too).

I?ve seen the Sherwood data etc and I know the KX3/K3 are ?better? radios but we are a 100 watt low power station with a variety of antennas (Buddipole, OCFs, Hexbeam etc) and maybe the K2/100 to all intents and purposes is good enough such that we essentially nab as many stations as the K3 would with the same antennas.

Any feedback is welcome.

More marketplace incentive to replace rather than to repair.  Then
again, no longer having a workshop or good close-up visual acuity any
more, replace is the most viable option for me.

Replaced by Jetstream JTPS32MAB. Probably same as MFJ-4230MV and many

Astron used to make s great supply. I have the same problem with RS-35M less then a year old.
Worked fine for 8 or 9 months then developed a bad hum or buzz. I got tired of listening to it and pulled out a 35 Amp switching supply. Haven?t had the time to pull it apart yet.

Well, i have received many helpful replies both publicly here and in private
emails.  Thanks to all for those ideas brought forward.

What I've gleaned to be most useful from your responses has been the
suggestions to investigate the power cord with power poles connecting the K3
to my switching power supply.  Per those inputs I've fabricated a shorter
(5') cable and insured that I used the crimp terminals rated at 30 AMPS. 
The initial result has been a reduction of about 30% of my measured voltage
drop (now 13.6 Volts in standby to 12.5V when key down 100W CW........
previously the drop was to 12.0)...............  Some background info. is
that the original observation of a voltage drop occurred as the K3 was
connected to my minimal-sized Solar Power supply.  After extensive
investigation, additional hardening in the wiring, and replacement of a
suspect imported power distribution strip, I was convinced there was no
voltage drop evidenced there.  The battery voltage measured at the input to
the referenced DC power distribution strip did not waver under key down
tests with the attached K3............. There remained however, the
above-mentioned voltage drop displayed in the K3 metering.

i plan to rebuild the afore-mentioned 5' power cable, this time soldering
the power pole lugs rather than trusting crimped connections.  My suspicion
that the power cable is suspect, so i plan to address those curiosities
before moving on to other possible cause.

Thanks again for your continued ideas and suggestions.
Regards,
Mike, K5MP

Speaking of meter lights: Those #47 bulbs never lasted long at 6 V, so I 
used to put a resistor in series with them. Nowadays, a white LED, 
rectifier, and a resistor would work fine, and you would never have to 
replace it again.

Be sure to use a DVM external to the K3 to measure the voltage at the K3. The input protection diode in the K3 will cause some drop (1/4 to 1/2 volt perhaps). What this means is that the K3 meter will always show less voltage than is really present at the transceiver supply input.

0.7 V for a regular diode. I believe Elecraft uses Schottky diodes for protection because of their lower voltage drop (0.15 to 0.45 V).

A little piece of cork between the TX and the front of the case fixed my 50's hum!? There was something similar from the factory that had fallen out over time.

I am building a Four Band Module K1.  I got my parts a little mixed up and
installed the 18 Pin U1 socket from the 2 Band Module.  The socket that came
with the 4 Band Module has "18" embossed below the top notch.  The socket
from the 2 Band Module likewise has "18" embossed below the notch, but also
has "A" embossed on the un-notched section.  I'm assuming (hoping) this is
simply a generic socket and the parts are the same: correct?

Tom,

An 18 pin DIP socket is a generic item.  Use it.

Our use of the power supplies was on mountain top repeater and remote 
base sites.? Access was generally time-consuming and sometimes 
impossible at various times of the year.? The Astrons, while they could 
be repaired and made to work ... at least for awhile ... were just too 
unreliable and unpredictable for such service.? We ultimately lucked 
into some Rockwell/Collins rack mounts that had been removed from 
service and were at a government surplus auction.? The were rock solid. 
We had to do a little modification to get the regulated voltage down 
from 18 to 14 but that turned out to be two resistors. They'll probably 
run until Antarctica melts.? Neither side of the outputs [there were 
two] were connected to the frame.? Only downside was that it took two

Howdy Jeff,

As it happens, there are several blind Elecraft fans out here. I can think of at least four just off the top of my head, and if I think about it some more, I can probably come up with more. I myself own a K2/100 and a KX3. One of these years, maybe I?ll get my hands on a K3s?by that time, there will be a K10 :-)

I?m not sure if the KX2 has the morse readout that the KX3 has (Wayne?), but if you?re thinking about using a computer, well?that seems like a bit to carry for a very portable rig like the KX2. If the KX2 has the morse readout that the KX3 has, that will actually read enough for most operations. Notably, it doesn?t read the menus, nor does it read memory channel settings, but it will read other settings and operating frequency, which are really the most important day-to-day things. 

If, however, you?re not a know code ham, note the spelling, there?s still a solution. It?s called the Hampod:
http://www.hampod.com/

This is a small plastic box with a 16-key keypad laid out like a standard DTMF keypad, and it has a Double-talk chi p in it. It will literally read every setting, every operation, everything that can be reported through the KX2 or KX3 serial port, make adjustments, and all kinds of fun, and it runs off 9-15 volts. It?s maybe a little speedy at $295, but if you?re already buying a KX2, it?s really a pretty nifty piece of kit. I?m actually curious to try the built-in cw or PSK decoders with it. 

Anyway these are fun little radios and you won?t be sorry at all.

Paul...
I've used my K2 on Field Days, operating CW on 40m into a temp dipole. 
I've had no trouble landing close to 500 contacts, and my goal this year 
is 600. Aside from the "elan" of using the K2 "in the field," the radio 
always performs flawlessly with more than sufficient sensitivity, 
selectivity, and features for the FD environment. DX contests from 
outside the ZI may present different challenges, but I would think it 
worth while to at least give the K2 a chance to show what it can do.

yep, OHM's law lives, even after at least 61 years since i first studied it
in preparation for my novice test.

Furthermore, I'm grateful for the outpouring of ideas and suggestions
received here on this forum.  I think I have learned enough to convince
myself that I have improved my situation as much as i can, and with what
remains, I can live with the resultant which appears to be due to the
presence of the referenced internal diode which some have suggested would
impose a .7V voltage drop.

>From received suggestions I replaced the input power cable with a 8AWG 6'
stranded copper pair with all the  power pole connectors firmly crimped to
the wires.  When plugged into the MFJ switched power supply i measure 13.6V
at the power poles on the power supply, and the same 13.6 is measured at the
power input on the back of the K3.  Under key down 100W CW test, the power
supply voltage does not vary at all, either at the power supply or on rear
of the K3, and on the internal power meter in the K3 I see a .8V drop to
12.8V......... that's near enough to .7V to declare victory as far as I can
see.

Having achieved what seems to be normal operations as based on those voltage 
measurements, I then disabled the MFJ power supply and moved the input power
cable on the K3 over to the DC distribution panel from the Solar System
batteries.  Much to my surprise and pleasure the voltage measurements
compared equally to what I registered in the hookup to the MFJ power source.

So, now that you have helped put this power concern to rest for me, I will
close out this concern as I turn my full attention to fine-tuning my solar
power system capabilities, such as incorporating a boost inverter for
raising and holding the input voltage at a level more friendly to the K3
operating efficiency.  

Thanks again for all your suggestions and ideas.
Regards,
Mike, K5MP

Hello Paul,

Regarding the KX3 station, the DX Engineering RTR-2 will enable you to use
a receiving antenna, and it handles the T/R and protection duties nicely.
I've been using one for a couple of years with a Pixel magnetic loop on 80,
40, and 30 meters. It also has a front panel toggle switch that allows you
to quickly engage the tx antenna for reception as well, giving you the
opportunity to use whichever one provides the best signal.

Now crank up the voltage output on the power supply to 14.1 Volts.   This will result in a cleaner signal and lower the amp draw, thus reducing the cable voltage drop slightly (that Ohms Law thingy again). 

Enjoy your rig. 
ps: I?ve replaced the circuit board in several Astron power supplies recently and they were all set to 14.1 Volts right from the factory.

The challenge in the phone contest at 100W with compromise antennas is being
heard. This depend on the quality of speech processor and microphone or
equalization. The difference between excellent and not so speech processor
can easily be 1-2S.  

K3 has an excellent speech processor with equalization. K2 has compressor
and sounds OK but not dramatic with good microphone. IMHO KX3 processor is
not too efficient and even below K2. But KX3 has an equalizer allowing any
mic to sound good. 

For portable radios, the best procesor seems to be in FT-891. 

A good contesting combo if one can afford it is KX3 driving Expert 1.3k for
> 1 KW. The Expert weighs 20 lb and has ATU to trim less than perfect
antennas + automatic 110/220V switching.

To put a wrapper on this thread: I ended up ordering two 400Hz filter direct from Inrad.  They had them clearly marked as eight pole and said they were mount-compatible with the K3.   I had email exchanges with K3 support, most of which were helpful, but the question about a KFL3C-400 eight-pole filter went unanswered.  They seem to have a problem in this area.  Not exactly sure why.  Uncharacteristic.   So, I have two 6-pole 400Hz filters for sale!

Just an opine.  Since these are ROOFING filters, and not the means of determining the radio?s ultimate selectivity, you may not notice a substantial performance improvement of the radio with 8-pole vs 6-pole filters.

I have my flame suit on, just in case ? (it can be almost guaranteed to be needed around here).  :-)

Grant et al;

I can agree that many hams do not understand the application of 
"filters" in a radio, specially today with the advancements in DSP 
technology.? I find today that many many hams rely on "old school 
methodology" to justify what they do.? They, for the most part, seem to 
shy away from learning and understanding how things work today.?? Times 
have changed. ? In fact I see more and more the adage of? "what someone 
said" taking precedence.

The roofing filter concept protects the AGC, just as the DSP provides 
the selectivity.??? For strong signal operations one should have both.? 
But in many cases in our normal QTH environments, little is to be gained 
with added roofing filters.

This is a slide presentation from Sherwood Engineering on FILTERS, why 
and why not. http://www.sherweng.com/documents/Barc2008.pdf
<http://www.sherweng.com/documents/Barc2008.pdf>

I'll take his word for it. ? It is well worth the read.

Yes. The K2 is compromised in several ways on SSB. First, the audio 
stage is low on gain, so a mic doesn't hit the peak limiter hard enough 
to do much. Second, the audio chain has a flat response, so low 
frequency components of the voice waste transmitter power. I did a mod 
for mine, which W3FPR knows about, that provides some low end rolloff 
and increases mic gain by about 6dB. That helped, but it's nowhere near 
what the K3 and KX3 are capable of.

Second, the narrow settings of the receive filter are produced by 
stagger-tuning of the multi-stage CW filter, and their combined response 
looks like a side view of the Rocky Mountains, so the accompanying phase 
shift distorts the RX audio enough that using the narrow settings often 
degrades speech intelligibility (that is, it makes voices HARDER to 
understand).

Thanks to those who contacted me.  Nobody seems to have a Rev B Schematic!

The possibility of an exchange unit has not materialised so as the KPA3 is still mine, I decided a bit of disassembly was in order before taking it to be serviced.

Findings upon removal for testing:

C43 and C44 passed testing with a Peak LCR45 - refitted

R27 OK - refitted

D7,8 & 9 OK with Peak DCA75 - replaced since I could get these and they are very cheap

D10 Pin Diode tested as ?no component? with Peak DCA75 and multimeter shows open circuit

The MA4P4006B-402 600V Pin Diode does not appear to be available for sale in the UK, but I am checking with the service centre.

Conclusions:

One fault found, need to repair that before further testing.  Since I do not know the history of the unit, which was a Silent Key sale, there is no information about the likely cause of this failure.

Many thanks once again - I will post the final outcome on the reflector, once all is working again.

Subject: [Elecraft] An ideal amplifier for the KX2
Message-ID: <CANoJsHZWWmvBfAtJq5jqnP9Li1tWXuhE-n3PWHdZ+jB-7YqVww@mail.gmail.com>

I've just finished building up a superb amplifier kit from Victor and Yana
at eb104.ru that uses phase-change cooling. It will output 750 clean SSB
watts with 4.5 watts of drive once I replaced the 10-dB attenuator pad with
a 4-dB pi pad, namely a shunt 220, a series 24, and a shunt 220. The
attenuator is easily accessible without any disassembly. (Arithmetic would
suggest that the unmodified amp could be driven to near full coutput by the
KX3.)  It employs one BLF188 as the active device with well designed
protection from excessive drive, SWR, or drain current.

The amplifier is elegantly constructed, complete, and tested. You need only
install it and its connectors into the included enclosure. As I should have
expected from phase-change heat transfer, it runs cooler than any amplifier
I have ever operated. See details at

https://eb104.ru/internet-magazin/usiliteli-moschnosti/eb1200-heat-pipes-cooling-system

I have built many amplifiers using eb104.ru modules. Their boards are of
the highest quality in design and performance.

You will have to supply 13.8 VDC, 50--53 VDC at maybe 35 amps, and an
external bandswitch box with a wafer switch, since the amp is designed to
be bandswitched by a transceiver via the DB25 on the rear panel.  To play
it safe I would use a PNP PTT  circuit to protect the KX2's key out circuit
from the current drawn by the (three) bandpass filter relays in the amp.

Thanks all for your perspectives and the info on the audio chain is very informative and hadn?t really thought of that one. Simplistically I thought the audio on all three would be similar but now I know.

I have a K2/100 I built and maybe like all K2 owners have a fondness for it and would like to see it used more.

I?m sitting in Houston airport waiting for my flight to Costa Rica with two KX3/PX3 combos which we will use for this contest but its a bundle of gear to tire together especially when you add laptops, KXPA100 and my home brew SO2R box that all in all makes the K2/100 attractive albeit minus the panadpter.

Having a panadpter does help in a contest and retrofitting one to a K2 either via an IF tap or an external SDRPlay type solution probably enters the comparison at some level.

Keep the comments coming!

Hi Mike,

This will be fixed in the next release. For now the setting is fixed at either 500 ms or 1 second per update. This applies to the audio voltmeter/dBV voltmeter functions of the DISPLAY switch.

Ignacy and All,

Everything Jim says is true, but still, the K2 can be a very good 
contest transceiver.

The K2 is indeed a viable contest station, either portable or home 
station - especially for CW, but a bit less so for SSB for the reasons 
that Jim stated.  VOX is not going to work well, so use PTT.

The normal SSB filter (OP1) - normally used as receive FL1, and always 
used for SSB transmit is a good flat filter that provides a fine 
response if the filters are properly aligned to place the bandpass 
correctly.

The SSB FL2, FL3, FL4 filters formed using the RF Board crystal filter 
are a bit 'ragged', but if properly aligned can be used successfully if 
one is willing to sacrifice 'critical ears' and maintain communications 
when narrowing the receive filter becomes a necessity.  I would not run 
a contest with those filters switched in, but would use them to narrow 
the filter to eliminate QRM in the midst of a contact.  That does 
require the filters be optimized.  The manual gives workable filter, but 
are not optimum.  To adjust for optimum filter, one must adjust the 
filter width and the passband position using a wideband noise generator 
and observing the passband position with an audio spectrum analyzer such 
as Spectrogram or SpectrumLab.

For contest operating, I suggest setting the K2 SSBC parameter to 4:1, 
and for normal operating set it to 3:1.

As for mic gain, there are only 3 settings.  With an electret type 
microphone such as the Elecraft MH2/MH4 or the ProSet-K2 (or Proset-iC), 
an SSBA setting of 1 is normally adequate.
For dynamic microphones, a setting of SSBA 2 is normally adequate except 
for the more recent Heil elements such as the HC-6 which may want an 
SSBA of 3 to produce adequate output.

Jim's mod for reduced low frequency response of the KSB2 involves 
replacing 2 capacitors.  C34 should be replaced with a 0.47uF capacitor 
and C32 replaced with a capacitor in the range of .0033uF to .005uF.  I 
normally use .0047 with success.

The KX2/KX3/K3/K3S has both transmit equalizers, plus better compression 
and mic gain handling, but a K2 with properly aligned filters is 
entirely usable for contesting and is better than a lot of other amateur 
rigs out there being used in a contest - except for the hard-core 
contesters who insist on having only the 'best' transceivers.

73,

I know the KPA 500 is designed for SSB and CW, but I have always wondered if you can use a KPA500 on AM and, if so, what would be the maximum wattage you should use? The manual
doesn?t say anything about it.  73 Mike KF6KXG

No reason why not.  If it were me, I?d keep the unmodulated carrier out to around 90-100 W to allow for some headroom.  There?s no reason to push it past that.

I am new to the List.  Just acquired a K2 am learning a whole lot!  I would
like to
install the DSP Option in it because I am primarily a SSB operator.  If
anyone has one to sell, please let me know.  Shortly I'll be putting an
order in to Elecraft to be
able to purchase updates, mods, and options since it is a very low s/n.  I
am glad
the List is available because I have found similar Lists helpful with
Collins, Tentec,
Swan/Cubic, and other old gear. Looking forward to proceeding down the
Elecraft path.

Mike,

You can use the KPA500 on AM at the full 500 watt rating.
BUT remember that the power is Peak to Peak.
So you will not get 500 watts of carrier and a total of 500 watts of 
sideband energy.  You will get 250 watts of carrier and 125 watts of 
sideband energy in each sideband - for a total of 500 watts PEP.

If you are long-winded on AM, you should reduce the power - check the 
temperature.

73,
Don W3FPR

The peak of a 100%-modulated AM signal is twice the amplitude of the 
unmodulated carrier, or 4 times the power.? So the keep the peak power 
below 500W, the carrier power should be no more than 500/4 = 125 watts.

You might need to keep it somewhat below that if you make long 
transmissions.

Just as a point of interest, with sine-wave audio at 100% modulation, 
each sideband has 1/4 the carrier power, so even though the peak power 
is 4x the carrier, the total *average* RF power is only 1.5x.

Message-ID: <CAP4v5qzrvpVbym__UdUsKq7iKkE-k=g46Opb33OdEbv3YnkaFQ@mail.gmail.com>

The other day I finally  got up the nerve to perform the temp compensation
procedure on my KX3. The process went fine as far as I could tell (the
Elecraft instructions we great), I tried very hard to limit the temp rise
to only one degree every min or two. So then this morning, I am looking at
my WSPR mode results on 80 meters. At 2 watts I am still being occasionally
reported as drifting 1hz drift, mostly negative, (and saw one -2 hz
drift). I seldom run more than 2 watts any more, and the rig only gets
barely warm at 2.  So I guess I am trying to understand what is within spec
as regards these FT8 / wspr types of modes and performing the temp comp
procedure. Is all well now and these are only anomalies? I will wait until
I can get some reports on 20 meters wspr, because I know it was showing 2-4
hertz drift/minute drift on that band at 2 watts, it will be interesting to
see what it shows now if the band opens some. Is it possible to go back to
the original temp compensation values?
Thanks for any thoughts if you have any and 73's from snowy Spokane (we are
really seeing the snow pile up here it actually looks like winter out there

any idea if will be a new control radio for remote? Like K3/0 Mini with
remoterig integrated inside it?

Maybe for Dayton will have it?

A K3/0 that could directly connect over the internet with a K3s (K3s+ or
K4) is really needed.  The remoterig is relatively difficult and old tech.
The client server architecture like flex is using is what is needed.

 Back when I was traveling a lot I considered getting the old style K3/0(the full size one)and building all of the remote hardware into it, so it would be all self contained in one box.

Hi Mike,

I had to perform the temp compensation a few times.  A couple of those
times necessitated a retry due to operator error in the setup :-)  I
eventually achieved a level of proficiency in preparing to apply the heat
source.  Initially, I used a hair dryer the first couple of times.  But the
drift was still present.  I then used an incandescent light bulb (60W I
believe) in a small articulated desk lamp.  This worked much better as the
temp rise was more consistent over a longer period of time.  After that
successful calibration, I have yet to see any drift or be called out for
having drift by another ham.

The KX3 temp compensation is brilliant for a fanless rig once it is
calibrated correctly.

regards,
Brian

I couldn't agree more. I'd buy the hell out of that combination. I'd go
further, and would like to see a smaller physical sized remote for easy
traveling. Fewer physical controls but much less size and weight.

That?s the idea, all contained in one box, wired internally

I know is possible, and already done, but never to sell it

But Fred?s idea is better, just don?t know if it?s possible with actual K3 or K3s or will need a complete  new radio

Jorge

It would be ideal to also include the band scope of the p3 into the
solution.  Perhaps the integration of the solution could be encapsulated
into a new P3.  The functionality of remoterig can be in the new P3, and
the P3 scope data could be sent digitally over the internet as well.

I use the existing K3/0-Mini and Remote Rig with my K3 and the Flex-6700 through Maestro remotely.  Both approaches have their advantages and disadvantages and in essence we?re comparing apples to oranges.  

The K3 approach through Remote Rig is admittedly ?kludgy? given external boxes, cabling, and settings.  However, once up and running it is very good and reliable. Most importantly, the system requires little bandwidth for radio control and audio. I can use the K3 remote system controlling a K3 station in rural southeast Georgia which has a DSL connection and max upload of 1.2 MBps.  In most cases, it is 768 Mbps.  In addition, it is a ?self-contained? system where no one else has connectivity and the connection is directly between the remote and the K3.  I am not dependent upon Elecraft to maintain a system for managing my connections.  However, this approach also requires separate means to manage the KPA500 and KAT500.

The Remote Rig RC-1216H provides a web interface for the KPA500 and I use a second RC-1216H to control the rotor (Green Heron RT-21 managing an Orion Rotor).  Of course, there isn?t a panadapter remote option which would take uplink bandwidth. What I miss is the direct controllability of the KAT500 which requires the KAT500 utility to be controlled remotely.  I?ve done this using a Serial-to-Ethernet converter, but I don?t llke it because it requires a PC to run it.  I hope at some point that Remote Rig would upgrade the firmware to manage the KAT500 so that I can use any web-capable device (iPad, iPhone, Mac, PC, etc.).  

Overall, the system works very well and I?ve been using it since September 2014 without problems.  I now keep a K3/0-Mini system at two different locations (Texas and New England) both of which cannot support a ham station on site.   

The Flex System overcomes some of the weaknesses of the K3 approach and of course it has a remote panadapter capabiity.  But it has taken Flex over five years to provide the remote capability at significantly higher cost and requires greater upload bandwidth.  SmartSDR 2.0 was introduced in 2017 which means for four years I could only operate the Flex-6700 when at the shack.  Flex?s approach is dependent upon a server-based system to establish a secure link, a license fee if you?re upgrading from Version 1 to Version 2 or Version 2 to (just announced) Version 3 of SmartSDR.  Flex Radio has to maintain a server system to control access remotely.  The PGXL amplifier can be controlled directly through Maestro or a PC running SmartSDR v2.xx operating from a remote site.  However, the ?Tuner Genius?  that is promised to go with the PGXL has not been released, so I?m limited to using my EFHW antenna to the KAT500 and the K3 setup since I do need to use a tuner with it.  I will say that the bandwidth requirements of the Flex under the current V2.49 SmartSDR is significantly less than in the past so it works more reliably in ?Low Bandwidth" mode.  I also keep a Maestro in both Texas and New England.  

Having two different remote systems with different feature sets does provide some advantages:

-Redundancy. In the event one system has a remote issue, I have the other to use as a backup.

-Flexibility.  I like to ?listen? so much of my time is spent listening or participating on nets.  The K3 setup works well since I?m not particularly ?hunting? for signals where a panadapter would be useful.  Simply turn on the K3 and I?m on the last frequency I was tuned or I can enter the frequency of interest.  I have the tuner and amplifier as needed, and 500W is usually more than sufficient for my needs.    The Flex is more helpful if I?m searching the bands with a panadapter/waterfall, but the PGXL is only helpful on 10-15-20 where I have a yagi and don?t need to a tuner capable of handling the PGXL.  Due to bandwidth issues, the Flex system does sometime ?hiccup? due to missed packets though this happens a lot less than previously.

-Space.  I spend 90% of my operating time running remote.  At my locations in Texas and New England I have the Maestro and K3/0-Mini sitting on my 30? x 60? office desk by the 27? Apple Display with West Mountain Radio external speakers that can be used with either system.  The Remote Rig equipment, cabling, network ethernet switch, 120 VAC surge protected hub that powers the Remote Rig equipment, network switch, Maestro, Speakers, K3/0-Mini are either sitting on the floor or held in place with cable ties attached around the desk legs, out-of-the-way and out-of-sight.  Of course, the ham shack itself in Georgia is a different matter given the amount of equipment installed, but the operating position has the real estate to handle it. (approximately 12 ft. x 30? of desk space).  

-Equipment Complexity:  The K3/0-Mini and Remote Rig RRC-1258 are relatively simple devices.  I?ve not had any issues with these devices and while there have been firmware upgrades they are few and not necessarily required.  The Maestro is a much more complex piece of equipment which is essentially a device with built-in tablet that takes significant time to boot up and has firmware that controls the various knobs and indications and of course communicates with the Flex server to establish a connection to my Flex-6700.  Any update to SmartSDR (the most recent was last December 2018 to v2.49 while Flex has announced that v3.0 will be available in March 2019) requires an update to the Flex-6700 and Maestro.  This can be done remotely, but it also reflects the greater complexity of the system.

My original Maestro (purchased new in 2017) has been recalled once at no charge and sent back once for non-warranty repairs.   

-Isolation.  Running remote reduces the potential for surge issues where I?m actually operating as there are no external antennas.  

At the ham shack in Southeast Georgia, I have the K3 equipment physically separate from the Flex Equipment going through separate ethernet switches and isolated with Fiber Optic Converters for CAT5 connections to help reduce the probability of surge problems or a  ethernet switch failure in the shack taking down both systems. RF connection of both systems to the antennas and dummy load is thorough an Antenna Genius which provides high isolation between antenna ports. The DSL modem and separate router are in the house while the ham shack itself is located in an air conditioned room located in the detached garage.  I run a fiber optic cable between the house and ham shack to further isolate the network equipment in the house from the shack. 

Bottom line is that I like both systems and each system offers capabilities that the other does not have.  Given that I?m over 1,100 miles from the ham shack most of the time, I?ve benefited from redundancy because things can go wrong and cannot be fixed until my next trip to southeast Georgia. Over the past year I?ve had issues with one or the other system but usually the other system is still up and running.  

From the user?s perspective, I do suggest that one needs to to carefully consider how exactly they will operate their system and what level of investment ($$$, sweat equity, real estate) they?re wiling or able to put into a remote system.  Flex?s approach is certainly successful, but it is a complex and more expensive system that has taken many more years to develop than what Flex initially announced.  Electraft?s approach is ?simpler? in terms of making it possible to operate remotely, but it does appear relatively ?kludgy? given that it could certainly be streamlined if they thought it is worth the time and effort.    If one is focused on ?pickup and go? remote operation, the Flex Maestro (or SmartSDR on a laptop or SmartSDR for iOS on an Apple iPad) is certainly easier to manage than taking the K3/0-Mini with remote Rig setup.  i have transported both the Maestro and K3/0-Mini w/Remote Rig in their respective Pelican Cases between locations before so I appreciate the steps needed to take down and setup this equipment.  I later purchased used K3/O-Mini and Maestro devices to eliminate the need to transport (and take up space in my vehicle) between Texas (Fall/Winter) and New England (Spring/Summer) when cargo space is at a premium when transporting the XYL, family dog and the clothing and other items needed at the other QTH.

That is something that I requested some years ago and again this year.? 
To make a box that allows control of the K3(S) using the same port as 
the KPod plus a connection to Line in/out for audio.

Using something like an FPGA, with networking integrated, it appears to 
be a simple matter to convert the K3(S) into a network device (but WELL 
above my ability level), which would simplify remote operations without 
the need for a computer (and capable of using battery power).? A 
matching app (or at least the data exchange) would complete this; tablet 
ops are pretty nice, BlueTooth to the tablet/phone for managed audio.

I've worked around it with a computer, TeamViewer and Skype, but there 
is no reason it can't be simplified.? Using the phone internet, one 
could put up a remote where needed (EMCOMM or fun).

I really think that it would be a very useful addition to the K Line; 
when they have the time.? It would place the K3(S) next to the Flex for 
simpler remote ops.

The app should also consider management of an amp, tuner, rotor or other 
auxiliary devices; if it gets that far.

Barry,

I have been using serial to ethernet servers for over 10 years to 
control rotors, amplifiers and other serial devices. You set these up 
once and can forget about them. You install a virtual serial port on the 
control PC for which you can use any kind of client software to control 
that device, but there is of course no web interface. No local PC on the 
radio side needs to be running. I use these devices instead of the 
(expensive) dedicated RC-1216H devices that only provide a web 
interface. My favorite ones are the Lantronix UDS2100, which I have 
bought over Ebay.

Note that the WebSwitch 1216H (not the RC-1216H) allows rotor control 
and also has a serial port server to provide a virtual serial port. This 
port can however only be used for the rotor, plus the web interface and 
virtual serial port can not be used at the same time.

Subject: [Elecraft] KPA500 new owner questions.......
Message-ID: <CACcBhqH=PZJQHa-G8YQBkZ2a+waRDpqYMi67TddGvQHhCj4GNw@mail.gmail.com>

I have never owned an amp before and recently put together a KPA500. All
seems to be working well, but I have a few questions. I am using with a
IC-7300.

How important is the ALC cable? I notice it is not included in the Basic
Cabling Diagram in the manual but is discussed later in the manual.

If I were accidently to run 100 watts into the KPA500 will the PWRIN HI
Hard Fault/STBY protect itself before any damage is done. Would ALC protect
me from that?

Is it standard procedure to keep the KPA500 in line when turned off and not
in use? I see you may run up to 200 through the KPA500 in STBY.

Is there any concerns or settings on radio when running full break in on CW?

Thanks

The fault ability of the KPA500 is fast, BUT I would not test that with 
100 watts.? The tuned input can only take so much abuse.

ALC should be used as a secondary (emergency) limiter, not for everyday 
use.? It will cause distortion (in part from overdriving the amp).? 
Proper management of the input (power out, proper compression levels 
etc) is THE best way to manage the combination.

I agree with Rick just keep the drive power to the minimum needed to get
the 500 watts out.  Over driving will do nothing but distort the signal and
most likely eventually damage the amp. I use 18 to 20 watts to get 500 out
on 160 mtrs  and a bit more to get same results on the higher bands.

When I read in the manual where it says "never exceed 40 watts" that 
leads me to believe one should not do that.?? While the protection 
circuit is fast and there is a 3 dB attenuator that switches in 
automatically, from 100 watts down 3 dB is still over 40 watts.? I think 
I read here where someone hit the amp with 100 to 200 watts and now it 
needs repair.? In other words, "they let the smoke out of the box".

As to ALC, that is in my opinion and option and does not require the 
company to supply a cable or diagram.? After all, what connector type 
for "other radio" is required?? And in many cases, mine for one of my 
radios, there is NO ALC input.?? Thus I must BE VERY CAREFUL?? when I 
use that radio with my KPA500.?? As to using ALC, since your IC-7300 
does have provision for external ALC, my suggestion is USE IT!.? Page 17 
in the manual "Using ALC" is quite clear about this.?? And for what it's 
worth, with my K3S, I do have the ALC interfaced from the amp to the 
radio.? Just in case something goes amiss.?? With my radio that does not 
have ALC input, I must be careful to set the power correctly and then 
CHECK and RECHECK to see all is done correctly before transmitting.

My KPA500 is in line in all station configurations and operation. ? Two 
transceivers, 160M - 6M. ? ? I find no need to physically or externally 
switch it out of line.

I have not used ALC with any amplifier since transceivers switched to 
transistor finals. From what I have read on this list, using ALC 
improperly can cause distortion.  Just be very careful with your drive 
level. I believe that the KPA500 can handle 100 watts in bypass, 200 
watts may be pushing it. The KPA500 is a very nice amp and it is easy to 
use with any transceiver.

I have never owned an amp before and recently put together a KPA500. All
seems to be working well, but I have a few questions. I am using with a
IC-7300.

How important is the ALC cable? I notice it is not included in the Basic
Cabling Diagram in the manual but is discussed later in the manual.

If I were accidently to run 100 watts into the KPA500 will the PWRIN HI
Hard Fault/STBY protect itself before any damage is done. Would ALC 
protect
me from that?

Is it standard procedure to keep the KPA500 in line when turned off and 
not
in use? I see you may run up to 200 through the KPA500 in STBY.

Is there any concerns or settings on radio when running full break in on 
CW?

Thanks

That's correct. And it's not limited to solid state amplifiers. The 
owner's manual for my Ten Tec Titan 425 amp, designed around 1979 and 
using a pair of 3CX800A7s, provides an ALC input, but advises against 
using ALC to set power.

Yes, improperly or incorrectly using ALC with any amp or any 
transceiver, for that matter,? can and usually does produce distortion 
and splatter.?? Just look at some of the signals on the bands and 
observe the ALC overshoot which exists with many radios. ? And it is 
made worse by the addition of an amplifier in line. It isn't pretty!.?? 
Yet it has little impact on the on frequency signal as heard and thus 
the "great signal" complements follow. But look at the other factors 
where you will find "NOT so great signal".?? These points should be 
addressed as well.

You install a virtual serial port on the control PC for which you can use any kind of client software to control that device, but there is of course no web interface. No local PC on the radio side needs to be running. I use these devices instead of the (expensive) dedicated RC-1216H devices that only provide a web interface. My favorite ones are the Lantronix UDS2100, which I have bought over Ebay.

I?m currently using the Lantronics EDS4100 serial-to-ethernet which works well.  As you note, one creates a virtual com port on the controlling PC running Windows.  This device can manage up to four serial ports at the remote site.  Thus, I have the virtual com configuration installed on Win-7Pro machine in the shack as well as on a Win10Pro virtual machine running on my MacBook Pro running Parallels that?s with me.  

However, that?s the problem?  I want to use web-based devices because I have no desire to run a Windows in the shack or where I am.  A web-based device such as the RC-1216H is much more convenient, doesn?t require a PC to access and avoids having to specially configure the controlling computer such as is required to manage a Lantronics device that is only compatible with Windows OS.  I can?t tell you how many times I?ve used my iPhone, iPad, MacBook Pro, etc. to remotely manage my station to turn on/off devices (through West Mountain Radio?s 4005i) or even reboot computers (through Digital Loggers Pro Switch).  

> 
> Note that the WebSwitch 1216H (not the RC-1216H) allows rotor control and also has a serial port server to provide a virtual serial port. This port can however only be used for the rotor, plus the web interface and virtual serial port can not be used at the same time.


To further clarify:

The RC-1216H can be configured to manage the KPA-500,  the SteppIR,  ACOM-200A, Expert 1K-FA, and specific rotators.  According to the RC-1216H manual, ?At the moment it support Prositel rotators with the D-type control box, AlfaSpid rotators,  rotators controlled by Green Heron control box and other rotators with serial interfaces with the DCU-1 protocol.?  In my case, the RC-1216H is compatible with the Green Heron RT-21 control box. Along with managing the rotor direction, jt can also power on/off the Green Heron controller through a relay box (such as  from West Mountain Radio) that allows 12 VDC to power on/off a 120 VAC device.  Keep the Green Heron power switch set to ?on? and I have  remote on/off capability for the Green Heron itself through the RC-1216H.    Thus, I have two RC-1216H devices:  one to manage the KPA500 and the other to manage my Green Heron/Orion rotor system.

The Webswitch 1216H is certainly an alternative for rotor control and people do get confused with the two model designations.  When I ordered the RC-1216H from HRO, they sent me the webswitch 1216H in error.  I like the RC-1216H because it is a simple RS232 cable connection between the RC-1216H and Green Heron;  configure the RC-1216H to manage a rotor, and it basically works out-of-the-box.    There are eight predefined aziumth bearings that can be labeled as well as the ability to direct the antenna to a specific bearing.  

In summary, the trend is for more seamless web-based management of remote devices both in the consumer market and amateur radio as it eliminates the need for specific hardware/software to remotely manage devices.  If I could replace using KAT-500 Utility software with a web-based device such as the RC-1216H  to manage the tuner, I could stick with running Apple devices (and avoid running Windows under Parallels on a MacBook Pro) and be able to fully control my K3 station from anywhere (in conjunction with the K3/0-Mini).

I have had my KPA500 for around 5 years. I frequently feed through 200w from my TS990S.

I have also accidentally abused it many times by putting 100w or more into it or using the wrong antenna or some such operator error.

It has always just faulted appropriately and come back up smiling.

It is a tough little cookie !

And now the voice of caution.

I think the KPA500 with the KAT500 and my Flex are a wonderful combination.
That said, my KPA500 stopped working. It appears, after reviewing the logs,
I hit it with 75 watts and probably blew one of the diodes in the front
end. I can dig up the explanation if needed. It may have been a case where
it took me a while to realize what I was doing. In fact, I can't remember
the event other than it was logged by the KPA500. By the way... just having
that log available is valuable.

I now have the Flex set to 25 watts max out.

how about the entire front , or maybe just a thin portion of the front 
panel of the new K_ come off showing a connector for the internet,?? and 
or maybe a internal wifi node ..like a raspberry pi type....

walk off and log on !!!

Do not forget the 50V finals & the inclusion of predistortion.

The report that a KPA500 was damaged by 100 W drive had me coding a new enhancement to my Kenwood/Elecraft control interface the same day.  I now continuously monitor the TS-590 power setting and, if it exceeds 35 W, I assert the KAT500 key line inhibit.  The key line stays inhibited until the TS-590 power setting goes below 31 W.   The diagnostic output of the interface shows what happens (PC; is the TS-590 power set/read command).

Barry,

Understand your standpoint now, but that is the opposite of what you 
wrote below.? You said that you wanted to be able to run the KAT-500 
utility remotely, which prompted me to let you know about the serial 
servers that would be the solution. The Apple part of course makes that 
somewhat more complicated.

Hopefully someone on the list will now know about these devices which 
are wonderful to use for remoting.

Many years ago, I built a tube amplifier with what I thought was a 
fairly sophisticated ALC circuit. I could never get the ALC loop to be 
stable. I know a lot more about control systems now, but I still don't 
know how to get ALC around an amplifier to work, and apparently neither 
does anyone else. What I don't understand is why it's so hard with an 
external amplifier, as every transmitter has ALC for its internal 100 W 
amplifier, and that works fine. Why the same design doesn't work with an 
external amplifier is the mystery.

The problem with just limiting the drive power and using the 
transmitter's ALC is that, especially for solid state amplifiers, the 
required drive power can vary considerably with SWR and temperature.? 
That requires either riding the power control continuously or running 
your amplifier well below rated output most of the time. (Unless, of 
course, you're running a 2.5 kW amplifier, but that kind of margin is 
expensive.) So, if anyone could figure out how to get ALC to really work 
with an amplifier, I think that would be worth paying extra for.

You said that you wanted to be able to run the KAT-500 utility remotely, which prompted me to let you know about the serial servers that would be the solution. The Apple part of course makes that somewhat more complicated.

I don?t believe I changed anything in my posting.  I originally stated that I was already controlling the KAT500 remotely through a serial-to-ethernet interface.  (My original post stated, "What I miss is the direct controllability of the KAT500 which requires the KAT500 utility to be controlled remotely.  I?ve done this using a Serial-to-Ethernet converter, but I don?t like it because it requires a PC to run it?)   By ?direct controllability? I mean not using a PC running specific software (KAT500 utility)  requiring virtual com ports and instead using a web-based interface such as the RC-1216H for ease of use and compatibility with a multitude of devices to control it.  Until such an interface is available, however, I?m forced to stick with the current solution of using a PC, virtual serial port(s), serial-to-ethernet converter, and KAT500 utility software.  

Much about remote operating boils down to personal preference.  There is no ?right? answer; rather how one uses their station,  lessons learned over time, and new technical offerings will cause evolution of how ?best? it can be done on a case-by-case basis. How I manage my station today is totally different that what I did back in 2014.

I agree these devices are very helpful;  without the Lantronics EDS4100 my setup would be much more ?kludgy? to manage the KAT500 remotely.

This fellow seems to have a good handle on the ALC issue as it relates 
to overshoot in the transceiver.

Here Tom goes into the discussion of good ALC vs. bad ALC systems.

Thank you to Don, Alan, Bob, and Grant for your responses to my question. When I use it for AM, I will keep it to around 75 to 80 watts to have a safety margin. 73 Mike KF6KXG
