[Elecraft] Power out problems Rev 2.72

[Frank Lammel]

Hello,

a friend of mine found a strange problem with his new K3. His setup:

1.
PSK31 (DATA-A), LINE IN = 5. PWR OUT set to 120 W, measured PWR at 
PWR-meter: 5 W.

2.
Then tap A/B. Switch to SSB. Measured PWR=30 W. After about 25-30 sek of 
  whistling into the microphone PWR out is 120 W.

3.
Tap A/B again and switch back to DATA-A, PWR now is 25 W.

4.
Switch off and back on the Rig and you will start again at point 1...???

Any idea?

ATU is on the whole time, however SWR is about 1,5. Tested was on 80 and 
40m with no difference.

vy 73!
