[Elecraft] Wierd SSB problem on my K2 on 20M

[Ron D'Eau Claire]

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.

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.
