[Elecraft] K3 tx power issue

[Frank Lammel]

Hello group,

a friend of mine has a strange problem with his tx power after upgrading 
to firmware 3.03. However I couldn't reproduce it with my K3 (also 3.03) 
so I'm asking here.

Following test: QRG 3,67 MHz LSB, no ATU, SWR 1:1,2 whistle to the 
microphone (Heil) TX pwr max about 80 W

Tap xmit, pwr=120 W, again whistle to the mic, now also 120 W. Now it is 
ok until you change the band or power off/on the TRX. Then is starts 
again with 80 W. About the same with USB. Also the same with ATU.

Without PA he has 8 W when whistle, then xmit=12 W, now also 12 W when 
whistle.

ALC about 4-7 bars. A calibration with the utility didn't solved the issue.

Any ideas?

Many thanks in advance!

Frank, DD7ZT (for my friend Dennis, DG6HD)
