I see some reports of K3 overshoot when changing bands or adjusting
drive. That would cause excessive drive. Performing the re-calibration
procedure may correct the problem.

This morning, starting the CWT, every few transmissions my amp was
faulting with the indication of excessive driving power (~67 watts vs
33 watts normally). Each time, it would fault once, then operate
normally for a dozen or so transmissions before the next fault. Then,
about 10 minutes into the hour, the faults stopped happening. The K-3
showed 33 watts throughout
I checked the KPA-1500 log, and all it shows is the "power input"
fault. What could be causing this erroneous indication of excessive
drive? A sticky relay?
