Andrew, Plug the KSB2 in again and be certain that it is properly positioned on the headers. It is easy to misplug the KSB2 - if you see the standoff and TP2 properly aligned with the holes in the SSB board, it probably is mounted correctly.
As a check (but not a permanent fix) slide a small sheet of paper between RFC1 and RFC2 and the adjacent crystal cans. That is a quick check of whether or not the windings of the chokes are shorting to the crystals - if they are, rewind the chokes being careful not to scrape the insulation on the wire. Check the orientation of the diodes - all of them should have the banded end away from the board. Lastly (or maybe best doen first) check the soldering carefully, particularly in the crystal filter area. 73, Don W3FPR > -----Original Message----- > > The problem is that the receiver became very quiet.
