[Elecraft] k-2 atu

[Don Wilhelm]

  I assume this is a K2/10 with the KAT2.
It is unusual for the diodes in the KAT2 wattmeter to be damaged by a 
static surge, but it can happen.  I would first check D1 and D2 in the 
KAT2.  If they check good with an ohmmeter (normal diode check), then 
the wattmeter in the KAT2 just needs to be balanced and properly 
calibrated.  You will need an external wattmeter to do the calibration.

The K2 uses the wattmeter output to control the power output, so if the 
wattmeter is not correct, the K2 microprocessor will not have the 
correct information and thus will control the power at the wrong level.
