[Elecraft] Help - Fluctuating output power ok K2

[Paul Webb]

Hi

I thought I had a similarly problem with my recent build K2 (5324) but =
it
was me, if your using the Tune Button to key the transmitter you will =
find
this happens just as you have written, the tune button bypasses the =
power
control circuits and the power level will jump all over the place , the
power control will seem to be very erratic and not smooth, if this is =
the
case for you, plug a key in the k2 and use that, when I did it was =
perfect.
I hope that=92s your problem too.
Good luck
Paul
