Shift the BFO frequencies so your spectrogram display shows that you are
cutting off a bit more of the low end (end nearest the carrier) and leave a
little more of the high frequencies (farthest from the carrier) inside the
bandpass.
Spectrogram is great, but I'd never count on a scope display to tell me what
my signal really sounds like! The final settings are just too precise and
vary with the mic you are using and your "ear". That's why the SSB module
instructions advise listening to your signal and making the final "tweaks"
of the BFO frequencies based on what you hear, not what you see.
Remember, only tweak the BFO frequency settings for OPT1. No other
filter/BFO setting combination is used for xmit, no matter what filter you
have selected for receive.

Hi,
my SSB signal is a little bit too bassy after i have modified my ssb-modul
from 2.0 to 2.5khz. The filter setting for TRX is OP1 in receive mode with
lsb and seems with spectrogram full in range between 0.2 and 2.5khz. What is
to adjust?
tnx for your help
Michael, DC0ZO
