With PBT control centered at 12 o'clock, tune the Omni 6 to a clear
frequency such that band noise is clearly audible. Switch back and
forth between USB and LSB. Does the tonal balance of the noise
(bass/treble) sound the same between the two modes? If it doesn't,
this is more evidence that the BFO oscillators need alignment to bring
them into balance.
