[Elecraft] K2 indicated power output funnies

[Don Wilhelm]

Bob,

I would have to have a lot more data for a more definite analysis, but one
thing that can cause 'funny' power readings is the diodes in the ATU
wattmeter.  They are sitting right out there on the antenna line where they
can be easily subjected to static discharges.  You may want to arbitrarily
replace them and see if the situation improves.  Re-calibrate the wattmeter
after replacing them.

73,
