[Elecraft] K3 variable power output

[Greg]

Don't know if you got a reply on this yet or not.  But try doing the TX Gain
calibration described in the manual again on ALL bands at exactly 5W and
50W.

Subject: [Elecraft] K3 variable power output


I'm running firmware 2.57 and I've recently noticed this...

An odd effect with the output power: it builds up from 5W to the
"dialled in" power over the course of about 5 QSOs after I  change
bands. If I stay in a band and increase the power from, say, 50 to 70
watts, the output immediately drops to around 5W and then increases to
70W in the next 5 or so QSOs. If I drop the power, the same thing happens.

I originally thought it might have been heating up - or something - of
the the new balun on my Windom antenna, but it does it with a dummy load
as well.

Any help would be appreciated.
