Pete,
Usually the first thing the folks at support will ask you to do is to
run the TX Gain Calibration, so yes, that is the first thing you should try.

My K3/100 #4275 has suddenly stopped making 100 watts, and is now
making 10-20 on 160-20 meters, and 45-50 on 17-10 meters , even though
the power control says it should be making 99 watts. On the way to
its current state, it cycled once through reduced power and back to
full power after a band change, so I suspect something was in the
process of failing. Any ideas where to start troubleshooting, or is
this something that warrants a trip back to the mother ship?
Addendum: In further testing, with power turned below 10 watts to
disable the KPA3, I'm now seeing less than 1 watt on 160, 8 on 80, 8
on 40 and 11-13 on 20-10. Turning the power back up to 100 watts, I
now have 20 watts on 160, 35 on 80, 25 on 40, 50 on 20, 85 on 15 and
100 on 10m.
Should I first try recalibrating the TX gain?
