[Icom] IC756 Pro PSK31 setup question

[icom@mailman.qth.net]

Hello,
   Have a question for IC756 Pro users.   I've run RTTY for a few
decades, generally with a 250 hz filter in the low IF, and FSK tx.  I'm
getting into PSK31, and it's a different setup.   I know it needs to be
in USB for best results (especially for TX), but how do you set up the
filter(s) for narrow rx?      I'd like to get the 1000 hz centered in the
band pass, and have it as narrow as practical with the DSP filters to
help the sound card.   What are optimum DSP settings anyone have found? 
I could take awhile and set test equipment up to find it, but thought I'd
ask here, see what information I might find.
