Buy an IC7000 ;-) I run my 7000 with 150Hz filter width for PSK31 and if that's not small enough I'll put one or both manual notches into play to narrow things further.
I can only define three filters and I have to do that at the rig, there is no provision to do it via CAT. But I can choose via CAT. They are forced to be centered at 1500Hz. I have setup 150Hz (for PSK31 and 63), 600Hz (for MFSK and Olivia) and 3KHz (for search/acquisition and MT63-1K) Right now I'm using fldigi because I need calibration capability but when the new HRD/DM780 comes out with calibration I'm looking forward to switching back so I can hopefully program some macros in DM780 to QSY to 1500Hz waterfall and dump the filter from 3KHz to 150Hz with a single button press. That way I can have a "search mode" and a "QSO mode".
