[Elecraft] K2 problems

[Don Wilhelm]

Oscar,

Instead of checking for the maximum power output, check to see if you 
have power control.
Operate into a dummy load - if you have the KAT2 installed, set the ATU 
menu to CALP and exit the menu.  Then set the POWER knob to 5 watts and 
see whether the power output goes to something quite above 5 watts.
If the power is significantly higher than that set by the POWER knob, 
then the K2 is not measuring the power output correctly.

If you have the KAT2, there is a problem with the wattmeter on the KAT2. 
  Most likely diodes D1 and D2 have been damaged by static coming from 
the antenna feedline.  Those diodes are the first thing to check.

If no KAT2, then D9 on the RF board is the most likely suspect.
