[Elecraft] K2 "not hearing"

[David Wilburn]

Not hearing well could be the need for the filter alignments.  Not sure 
where you are in the process, there are voltage checks you can make in 
the rear of the book, to help you understand where things should be. 
Check your regulators, 8v and such to see they are running properly. 
There is signal tracing information on N0SS or Don's site.  With general 
information, I can only give you general answers.
