I hope this hasn't already been figured out, sorry if it has. Rig is S/N 3162 I was CQing with the K3's digital voice recorder on 10 meters yesterday at 100w, I noticed that the SWR is bouncing up to the 3+ end of the scale on the voice peaks. I stopped, checked the SWR with the K3's bridge, SWR=1.6:1 and the MFJ-969 tuner also read approx. 1.5:1, so I kept CQing and after 5-10 minutes the circuit breaker for the PA tripped and wouldn't reset until it cooled down. Then I turned down the output to about 70w and CQed for about 20 minutes more with no more trouble. I took the K3 to a friend's QTH and the SWR bouncing to the 3+ range was the same but I didn't run it long enough to see if the circuit breaker would trip. Any thoughts?
