[Elecraft] [K2] Intermittent INFO 080 problem.

[Bill Coleman]

Over the years, I’ve had a little bit of trouble with my K2 occasionally given INFO 080. The first time it happened, during a Field Day even, I attributed it to condensation building up on the inside overnight. Once it warmed up altering being turned on for a while, it was fine.

I’ve used this rig at four different QTHs. When I have had it in an air-conditioned, controlled environment, it has not given me any problems.

Currently, though, the shack where it is located is in a basement, and higher humidity can be a problem. 

Last night, this problem contributed to me missing 4U!UN on 80m CW. It took about 15 minutes for the rig to warm up.

Any suggestions on how to diagnose the root cause of this problem? 

This is a K2/100, with the KNB2, KSB2, KDSP2 and KAT100.
