I have had a similar thing happen to me also. I have been in a contest on a run freq. and suddenly the KPA500/KAT500 will fault. This is on CW. If I do a 'tune' the amp/tuner will retune and I can continue. Of course in the few seconds it takes I will usually lose the freq.

Always thought that it was RF getting into the KAT500 sensing as I can usually back off to 300 Watts, force a KAT500 re-tune and continue.
