Sounds as though there's still(!) an XFIL/BFO alignment problem.

1) Confirm that RIT (or XIT) has not been enabled.

2) What SIDETONE tone (ST P) have you selected?

3) Please send me the CAL FIL DAC (or frequency) values you now
    have for both CWN and CW REV. AND the values for the filter
    CENTER FREQ. (or DAC value) for each bandwith you've chosen.

4) On what band did you perform the CAL FIL operation? If you did
    it on on 15M or above, you MUST INVERT the 'sense' of the side-
    bands... e.g. CWN XFIL values will be ABOVE filter center
    instead of being BELOW, etc.  40M is probably the best band to
    use when performing CAL FIL.

Cheers,
