K3: Low RF output only on 30 meters

Hello to the list!

I fired up my K3 tonight for the first time in months to try to work K5P
and the VP8 expeditions. Thing seemed to be working fine until I tried
working the VP8 on 30 meters. I noticed while sending that I didn't have
much output on 30 meters. Investigating, I get output until I hit the
threshold when the KPA100 kicks in. Full output until I got past 12
watts and them little or no output past that point. I seem to be getting
full output on the other bands. Any guesses? It's vexing...

That should read KPA3, not KPA100.

Scott,

Try running TX Gain Calibration with K3 Utility. If that fails, try
running it on 30 meters manually (see the manual for the procedure).
If it still fails contact Elecraft K3support.
