Hi Arliss, I recently had a similar problem with my K3. I contact Elecraft and received this response from Gary:
--------------------------------------------- See if it will produce 12w on 160-10m, and at least 8w on 6m, in Tune, with the KPA3 menu set to Bypass. The VFO should be near the middle of the band. Check the 3 LPA mounting screws on the bottom panel are all tight too. Be sure it passes VCO MD CAL too, and the ADC REF menu is set as shown below: --------------------------------------------- In my case, running VCO MD CAL cured it. I also asked Gary why this value may have been corrupted - here is his response: "It does change sometimes with age or changes in temp, humidity, or altitude. Not a bad idea to redo VCO MD CAL from time to time."
