Svend, In that case, try the "Cheap and Dirty Signal Tracing in the K2" that you can download from the Elecraft website Builder's Resource page then Troubleshooting Tips link. The direct link is http://www.elecraft.com/TechNotes/SigTr/K2%20Cheap%20%27n%20Dirty%20Signal%20Tracing.pdf.
That should reveal whether the problem is with the bandpass filter or the low pass filter. Once you have located the problem area, check the soldering - yes, even though it used to work, there could still be an unsoldered or poorly soldered connection that has finally developed enough oxidation to now fail. If the soldering is good, the next item to check is the relay K1 if the problem is in the bandpass filter or K12 in the low pass filter. Set the band to 40 meters and check for continuity directly across the relay contacts with your ohmmeter. The relays are latching, so they can be checked after power is removed from the K2. The schematic shows the relays in their non-selected position (i.e. when 40 meters is selected, there should be continuity between K1 pins 3 and 4, but not pins 2 and 3). 73, Don W3FPR Svend Spanget wrote: > Don, > > thank you for answering!
