QSK pops

Was on 15 in the ARRL DX yesterday and 15 was wall-to-wall signals. Somewhat frequently I'd get a pretty nasty pop in the audio. Sometimes it would happen when transmitting (QSK, roughly 30 wpm) and sometimes when receiving.
Anybody else hear this?
Cheers and 73,
Fred KE7X

Re: QSK pops

Fred,
I had a similar problem from time to time. I discovered it was a
station in Europe who had "stuff" on his signal that was all over the
place. If I were within about 10-15 KHz of him I had the problem. I
could see his sidebands on the spectrum display I was using. Other than
that, my KX3 gave a performance on all the bands that was really
impressive. As you noted, the bands were packed.

Hi Fred,
I heard you a couple of times on 15 meters, guess I was following you around on S&P, and your xmit sounded good.

I also did some running, ~30wpm, w QSK, and did not hearing any "popping" at all.

Elecraft K???

I occasionally get some very mild artifacts in QSK [QRQ OFF] in my
K3/KPA500 when there are messy signals in the neighborhood. With WF
averaging off, the messy signals sure stand out. There seemed to be a
number of unmodified FT1000's in EU.

Hi Fred,

I also was in the ARRL DX over the weekend but I did not hear anything like
you are describing. My K3 firmware is 5.09 and I have not upgraded as there
seems to be some 'rumblings' about 5.10's firmware not being exactly stable.
This is just a guess, but if you have 5.10 or higher (?) firmware, I would
switch back to 5.09 and see if you observe the same 'nasty pops'.[*] I am
assuming you were using your K3?

If you're using a KX3 (you didn't tell), this artifact is well known. Elecraft has actually tried to do something with it in the last beta F/W. The artifact seems to occure when there is a strong signal close by. Turning down the AF gain will help also.

Re: QSK pops

Yes.

I use both the ANT1 and ANT2 connectors on my K3 with a 40M EDZepp
connected via a balun to ANT2. I suspect a static discharge from that
antenna.

Last week, during the CWOPs mini-test @ 1900Z it knocked out the CWT
feature until I re-booted the K3. I plan a simple test, once it gets a
little dryer here.

Other suggestions appreciated.

Re: QSK pops

Static pops to the K3 can do things like induce a change to an unfortunate
bit or two in active memory, which later comes up as something that can't
be fixed without rebooting the K3.

It's a computer with some RF stuff hung off of it. Same things that make
you need to do a CTL-ALT-DEL on your PC can screw with your K3 as well.

I wouldn't recommend deliberately subjecting your K3 to shocks as a test,
though. That's really tempting Murphy.
