That's interesting, the RX I/Q signal lines appear to be reversed when
operating the KX3 on 2m.
I guess this makes sense, if you consider the 2m module is using the x4
output of the KX3's local oscillator, so that if you tune to 144MHz for
example, the LO would be running at 48MHz, so that in
I just found out that there's a Rework Kit E850607 for the KPA500. It
replaces Q5 (a FET) with a Darlington Transistor. The kit also includes a
Zener Diode, resistors and capacitors and includes changes to the 12 meter
LP filter. The kit applies to board REV D9 or earlier.

Of course, this is taken care of automatically in the PX3 :-)
Many of the better SDR Console software packages include a
configuration option to swap I/Q above 'N' MHz ... works for
KX3 on 144 MHz and K3 on 50 MHz.

I bet this has been asked and answered before. My new amp works perfectly.
Another engineering masterpiece from Elecraft. Is it normal for the amp to
be warm all the time whether it is on or off? Mine feels warm on the
bottom and shows about 32C when everything else in the shack is 24C to

I have not turned mine over to see how warm it
Hello Bob,
I would like to thank YOU for your trip to 4W. I was down to my last 4
zones needed on 80M and putting you in the log recently took that number
down to three zones left. Fantastic job with an HF9V for sure! You had
a very good signal on 80M.
The best part was a confirmation on
Nice site, Jim. Thanks for the link. Very nice
instructions on the amp, too.

Hello all,
I have spent a few months trying to fathom this and finally have given
up and need your help...
When in CW mode, and running MixW the following is observed:

display of MixW moves as expected, and any signals stay

I would think one would use digital soundcard programs in DATA-A mode.

Hi,
I have tried that... Same thing happens, the radio acts exactly the
same... It is some interaction with MixW I think... If I load FLDigi,
I get the same action, only all the time... I have disabled the
bands.ini in MixW to test, and that seems to make no difference...

I generally operate CW at 20KHz spans, with the bottom edge of the
screen at an even 20 KHz boundary. Seems to work well, occasionally
I'll find it different, not sure why.
In SS CW, I noticed that my lower span boundary was often 5 KHz up from
the normal value ... such as 14025. It seemed

Hi Fred,
When the K3 VFO A frequency gets outside of the P3 displayed span, the
P3 center frequency may change to keep VFO A on-screen, depending on the
setting of the FixMode menu setting. If you set FixMode to Static
then the displayed range should not change no matter what the K3 is
Hi Gary,
I will be one of the 3 operators from 8Q7DV (zone 22) during CQWW CW. We
are leaving from home on the 22nd of Nov and returning on the 4th of Dec so
there will be time before and after the contest. . Sure enough all the rigs
will be by Elecraft (actually a pair of K3 and possibly one
