I have restored a S-120 receiver but the original BFO is good only for CW. Could you suggest a suitable circuit (solid state) so I can listen to SSB (LSB/USB) ? Thanks in advance.
Try looking at this site. http://www.geojohn.org/Radios/MyRadios/S120/S120.html . I made this for my S-120 and it works pretty good. If you have questions just email him and he'll get back to you.
