[Elecraft] K3 output power unstable

[Björn Mohr]

I am right now in the middle of the SAC contest when I notice that the K3
has a problems keeping output power stable. I noticed some excessive high
output from the amp when investigating I found that my K3 set to drive the
amp with between 20-30 watt output depending on band, delivers substancially
more. Ouptut power pulsate between nothing and full power, delivering more
than 100 watts in bursts into the amp (designed for 30W input).

The problem is easiest to reproduce on 80 meters, but I am sure I saw the
power wobble a few seconds b4 stabilizing on higher bands to. Even when the
radio has cooled down to a PA temp of 34C the problem is there.

I think I read somthing about a similar prioblem somewhere, would apreciate
any leads that I might help to narrow down and eliminate the problem.
