It is difficult to suggest just where the problem may be. It could simply be a matter of filter alignment, or it could be something not right in the receiver path. Since the receive path is now complete (although the front end is now built only for 40 meters). so you can either debug it now or later. If you choose to do it later, you could encounter some difficulty discerning the proper adjustment of the bandpass filters for the initial receive alignment.
I would suggest that you follow the steps in the receiver signal tracing section (Troubleshooting appendix in the manual). If you do not have a signal source of sufficient amplitude, you can build the oscillator shown in the manual, or you might want to first try Tom Hammond's 'Quick and Dirty Signal Tracing' techniques that you can obtain from the Elecraft website. Proceed in an orderly manner to determine the failing stage or section first and then you can quickly home in on the actual component that is giving you trouble. Of course, the most likely failure is a faulty soldering connection or a misplaced component, so your first step should be the check soldering, then re-check the soldering, and after you have done that - check the soldering. 73, Don W3FPR > -----Original Message----- > > Been a while since I last kept up with the list.
