I dont' know when it happened, but I can no longer get full power out of my K3
(s/n 1417 FW 2.58 DSP 1.94). Using the tune control, power out will not go
above 63 watts. I can do the TXGN calibration at 5W and 50W with no problem.
But if I turn up the power, the output never goes above 63W, i.e. if I dial in
50, I get 50W, if I dial in 63, I get 63W, if I dial in 75, I get 63W, if I
dial in 100 or 120, I get 63W. It used to work ok. This is all into a dummy
load with an indicated SWR of 1.1-1. What could have happened? I've tried
going back to FW 2.45, but the problem still exists. Any help would be
appreciated.
