Actually, these aren't frequencies, they're the DAC counts, BUT they'll do 
just as well here... still give the same basic info. Just before step 12, 
in the instructions I sent, I think I should have told you to press 
[DISPLAY] to display the actual frequency. Told ya I was doing this from (a 
failing) memory.

>Per your diagnosis, I should head to the Spectrogram process!

BINGO!

First, ALL four of the CW REV BFO settings are set to the WRONG side of the 
filter. Their BFO frequencies (DAC values) should be ABOVE 146.

Additionally, I'm pretty certain the DAC value for CW NORM FL1 (OP1) is too 
low as well. the other three CW NORM values are probably OK, but you'll for 
certain know once you get into them with Spectrogram.

Obtain a copy of Spectrogram (I can provide a copy of the last Shareware 
version which was not 'crippled' after a certain period of time, if you 
can't find out on the web), and re-do the alignment.
