My K2 (#7235) recently started to have intermittent issues with power output in tune. Sometimes I get the power I set for a given band and sometimes I don't. Just now, if I set the level at 10 watts for each band, they all work as expected (with a little dithering in the 10ths position) when I press Tune except for 80 meters where I get 5 watts and 10 meters where I get 8 watts. This morning I got 2.5 watts in 80 meters and returned later to find it spot on at 10 watts. In each case, mode was CW and the vfo set for the cw section for each band. Usually, if a band shows low power and I hold tune in for 5 seconds the output level will climb up roughly a watt. I first discovered the issue last week when 15 meters went bonkers with the forward power waving up and down quite rapidly. I immediately stopped, changed bands, saw normal behavior then went back to 15 meters and it was right where I had set it. At that point, all bands were ok and no further problems were observed. Yesterday, things were as described above.
I have been testing with cables running from the rig through the SWR meter and into the station dummy. I did try an alternative dummy and checked the cables as well. If all bands acted the same, I'd be looking for a bias issue. Could there be something wrong in the relays?
