Unexpected K-POD frequency excursions

[Peter W2IRT]

Hi all,
In CQWW this weekend I ran across a problem that's been plaguing me in
previous contests too. With the K-pod connected to the radio (K3s) using the
supplied cable I'm finding that the main VFO QSYs down about 100-200 Hz on a
random basis. I tried loading the flat cable up with Mix 31 ferrites to no
effect. I haven't thoroughly tested this on all bands, but it definitely
occurred on 20 through 160. It was not a regular occurrence; maybe every 2-3
minutes it would happen. When I engage the VFO lock on the front panel of
the radio it stops doing it.

I has also been know to shut the radio off once every few days when I touch
the K-pod, which I'm attributing to static electricity. While I love the
functionality of my K-pod, I had to take it offline due to the frequency
excursions. I'd like to get a fix for this if at all possible. Suggestions?

Hi Peter,
Just an idea. Does the ipod generate a virtual serial port?
Do you have a bluetooth mouse?

Not quite my setup but I've recently had trouble with a usb serial cable randomly interacting with the Microsoft bluetooth mouse and the serial cable becomes intermittent. The mouse jumps randomly but also makes the serial cable behave strangely. I'm wondering  if a similar thing is occurring to you. My solution was to uninstall the mouse from device manager, shut down and restart...win10 pro installs a fresh driver for the mouse.

Nope, the K-pod connects directly to the K3s via an 8-pin flat cable,
terminated with RJ-45 connectors. The mouse is a USB wired mouse.

Peter,

Contact Elecraft support on this issue. Sounds like poor grounding/ESD
protection. They may have a service bulletin to fix the issue.
