[Elecraft] K1 receive problems

[Don Wilhelm]

Mike,

Assuming that all components are the correct value and are well soldered 
(worthy of a double check), then ---
The most likely problem is that the Pre-Mixer bandpass filter is not 
tuned to the correct frequency.

Do you have a signal generator capable of producing a signal on 40 and 
20 meters - Another transceiver working into a dummy load and a piece of 
wire on the K1 for an antenna placed near that dummy load should produce 
a good signal into the K1.

Do you have a 'scope or an RF Probe?  If so, you can tune the Pre-Mixer 
bandpass filter using that to observe the output at  P1 pin 6 on the 2 
band board.  Tune the inductors for maximum voltage.
