Power supply appears to be the problem. It is an Icom PS-125 that was a
"gimmee" when I got my previous rig, an IC-746PRO. The problem kept
repeating even after I reseated the power pole connectors in the K3 rear
apron. I then substituted a switching supply I have for my Kenwood TS-480HX
and ha
ed to it figuring that might solve the problem

was using. It did not repeat on another supply I had. Still haven't looked into
repairing the Astron, but understand it is not an uncommon failure.

After nearly two years of trouble free operation, I have developed a
repeatable problem. While transmitting on 40 meter CW on my usual antenna
the K3 suddenly shuts down. When I repower it, it comes back up fine, but
