Make sure to check diodes D16 and D17 -- they can be damaged by static
discharges and cause this. There is no firmware power calibration.

A fellow ham is having the following problem withhis K2:
A year ago, we installed the KPA100 which worked fine until recently.
Suddenly, the TX Power Control failed and the K2 will deliver either
9-15 W or - with the 100W PA switched on - up to 150 W into a dummy load.
I suspect there is an issue with the TX-ALC, but no defective diode was
found.
I personally don't own a K2 but is there a TX gain calibration procedure
similar to the K3?
Suggestions welcome - thanks in advance.
