Michael,
It seems that you may have placed the passband too low for a 2.5 kHz filter.
For any width filter, the low frequency corner of the passband should be
close to 300 Hz. When you install the 2.5 kHz width, set frequency markers
in Spectrogram for 300 Hz and 2800 Hz, then set the BFO to center the
passband between those markers.
If you need more detailed information, look at my website www.qsl.net/w3fpr
article on K2 Dial Calibration - Step 3 gives a lot of information about
setting the filters.

Subject: [Elecraft] SSB-TX-Signal is too bassy
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
