Jim,

Your unit is about the same age as mine (#3645) which was sent to Elecraft
a few months ago for what I thought would be installation of some upgrades
I couldn't do myself.  Turns out they found (and fixed) several items
including two resistors in the LPA that appeared burned and were replaced
with "more robust components".  Your problem sounds similar to what I had
seen but not as severe.

My K3 came back acting like a new puppy.  I'm not saying yours needs to be
sent in; just wanted to share what my experience with a similar s/n rig had
been.

Cheers,

Clark, WU4B
