My guess is that the BFO is misaligned, Tom. The BFO frequency changes according to the Upper or Lower sideband, and I'll bet that if you check the CAL FIL function with the counter probe in the BFO test point, you'll see the SAME frequency for either Upper or Lower sideband. Ham bands below 20 meters normally use the lower sideband, and that's probably okay. But when the upper sideband was aligned, the BFO was set on the wrong side of the signal and so USB on 20 meters and up (all the way through 10 meters) will not work on USB.
Ron AC7AC -----Original Message----- I know the BFO filter settings are saved with each mode and filter width...is there anything band specific that would cause the following symptoms... While listening to SSB signals: 160/80/40 LSB SSB OK 20M USB Rig seems to be stuck in LSB though the dial says "u". Signals are unintelligable and appear to be wrong sideband or badly adjusted BFO setting 17/15/12/10 USB SSB OK I just checked it out on 20M SSB for the first time a few hours ago so it looks like #1117 is not quite ready to play full-time yet.
