[Elecraft] K2 Problem - I let some smoke out

[Mike Murray]

Yep, that was the problem! In my haste to test the K2 after repairs, I
disconnected all optional stuff, including the RX antenna.  Naturally I
forgot all about that after a couple of days (CRS?) and thustly ceated my
own problem.

Thanks for the quick response and for all of the help you provide!
