Problem with KPA 100 (no power selection possible)

[Hartmut Kluge]

I enjoyed to build up the KPA 100. Transmit test with 5 watts was ok. But with POWER control set to output 20 watts power rises to 110 watts. If POWER control is set to 11 watts or higher  I  get always 110 watts output with good signal quality, but power selection is impossible.
Anyone have any ideas as to what I should do?

Harmut,

Is this a new KPA100 that has worked before or is it a new build?

Are you able to control the power output below 5 watts with the power
control with the KPA100 attached?

Can you control power on the base K2 if you remove the KPA100?

The answers to those questions will indicate where to look for the problem.
