[Elecraft] K1 Problems

[Bert]

Hi Steve,

Is the problem on both 20 and 40? If only one band check the band
crystal on the filter board.

C2 on the filter board is a fixed cap - no tweaking! ;-)

Also check connectors J6 and J7 on filter board. Bad connection - use
some DeOxit5 cleaner.

Start with alignment according to the manual, if you haven't done that.

Good luck!
