[Elecraft] K2/100 powercontrol will not adjust down power below 30meter!

[Tom Arntzen]

Hi folks!
This is a strange one for me.
I just got KPA100 in my K2.
I have worked nice DX after that and USB workes FB and I get very good audioreports.
But on 30,40 and 80 LSB I put out 150-180 watts into dummyload when I whistle in the mic.
I put out same power on settings 11-110 watts.
PA just won't regulate to 110 watts.
Tune take it down to 20 watts as it should.
CW workes as it should.
Transmitting into missmatch reducing power and shows Hi refl.
Going QRP 0,1-10 workes as always. FB.
In normal speech the powercontrol does have affect on setting.
USB work well below 30m. Behave normal.

Anyone seen this before?
