[Elecraft] K2: KAT 100 question

[Don Wilhelm]

John,

The relays and inductors in the KAT100 are pretty hardy, so unless you 
got a direct hit, I would not suspect them.  I would do the 'relay 
click' test from the menu to be certain all the relays are operating.  
After that I would suspect something has changed in your antenna and/or 
feedline - salt water corrosion perhaps?  The feedline could have become 
damaged with a lightning surge.  Be certain all the connectors are clean 
and tight.

73,
Don W3FPR
