[Elecraft] KAT100 Tuning Failure

[Don Wilhelm]

Jeremy,

The wattmeter in the KAT100 has been damaged - diodes D1 and D2.
You also have the KPA100, and it has a wattmeter with those diodes - so 
order 4 just in case those need to be replaced too.
We can get to the KPA100 after the KAT100 has been taken care of.

Failure to disconnect the antenna from the K2 when not in use will 
damage those diodes from static coning in from the feedline(s).

73,
Don W3FPR
