[K2] Intermittent INFO 080 problem.

[Bill Coleman-2]

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.

Bill,

Unplug and replug all options in the K2 as a first try, also try
removing the cable to the KAT100.  If it is the KAT100, try shortening
the cable between the KPA100 and the KAT100.

INFO 080 means that one of the option's firmware is not communicating
with the K2 MCU (or in the case of the KAT100, the AUXBUS path is too
long meaning the communications is too slow).
