David,
You can find out if it is an RF in the Shack problem or not by
transmitting into a dummy load. If the problem goes away, you can blame
it on the RF.
If RF is a problem, the proper place for ferrites is on the antenna
feedline to choke RF common mode currents on the outside of the coax
shield. Trap that RF before it gets to the shack.

More power seems to make it happen more often. I assume RF is getting into
the K3. Has anyone experienced this problem and if so, what did you do to
fix it? I've tried ferrites on most everything and that does not seem to
help.
