Likely you have one (or more) of the BFO settings tuned to the 
OPPOSITE SIDEBAND (wrong side of the filter center value). Re-read my 
docs and HEED the part about keeping all BFO settings for CW NOR (or 
CE REV) on the same side (upper or lower) side of the filter 
center.  This is a common problem for folks who haven't done it before.
