We don't have enough information to tell you where to look, it will take a bit of troubleshooting just to discover where to start.
The first step is to see what part of the receiver is alive. Do you hear any noise at all with the AF and RF Gains turned up all the way? If so, there is something there, if not the troubleshooting gets more complicated, so stop and let us know so we can advise on test techniques for the audio section. If you do hear something with the gains all the way up, the easiest next step is to try the "Quick and Dirty Signal Tracing" that is available for download from the Builder's Resource page of the Elecraft website. Should you not find the failing stage following that document, you will have to resort to following the Receiver Signal Tracing shown in Appendix E of the manual. There is a strong oscillator schematic shown there and you should consider building it to aid in your signal tracing. You can build it easily on a perfboard or even solder the parts together with 'flying leads' - I built mine 'Ugly Construction' style on a small (3/4 inch x 1 1/4 inch) piece of unetched PC board - I used a screwdriver adjust trimmer for the output pot. 73, Don W3FPR > -----Original Message----- > > I think I have a receive problem.
