[Elecraft] K2 - RF Board part 2

[Don Wilhelm]

At this point of construction, the 40 meter receiver should be as good 
as it gets - the following assembly only adds the other bands and the 
transmit section.

You do have a problem somewhere that should be investigated.

The easiest first step is to try the "Quick and Dirty Signal Tracing" 
technique that is in the Builder's Resource page at the Elecraft 
website.  If that does not reveal the area of failure, then one can 
resort to the Receiver Signal Tracing steps in Appendix E of the manual.
