[Elecraft] K3 and Alpha 91b

[Roy Morris]

Mike,
If your Alpha 91b does not trip out at 1500 watts on 75 meters SSB using other transceivers, then it looks as if your K3 may be either putting out a spike or the power output is not stable.  You might want to go through the following K3 calibration procedures:

1) Synthesizer Calibration
2) Filter Setup (all five precedures listed for each filter installed).
3) Reference Oscillator Calibration
4) TX Gain Calibration on all bands

Hope this helps.  Best 73,  Roy Morris  W4WFB
