For PSK31, I use the following:
Tx BW: 3000 Hz
LF Rolloff: 100 Hz (helps keep 60 Hz out)
TX Eq: 0 dB
You want the widest and flattest passband for the Tx. On Rx, I search
the waterfall with ~ 3 kHz BW, but if there is much QRM, it's nice to
"zoom" in using PBT and BW settings (or H & L cut) to bracket the
signal in as little as a 100 Hz window. It's good to have the Rx Eq
set to 0 db, also -- so you can work better with signals at the left
of the waterfall.
Hope this helps.
