The 746 allows you to select any filter for any mode, thank goodness!!

don't know much about the IC746. can you menu select cw filters for
ssb(digital) reception on USB? or do they only work in CW?

Has anyone tried using either a 250 Hz or 500 Hz filter for PSK31
reception? My Icom IC-746 (non-Pro) has no filters installed, and is
wide as a barn door on USB for PSK31. I wondered if either of these
filters would help, or would they be too narrow?
The pass-band shift does a fair job of eliminating QRM from one side
or the other of the selected frequency, but when there are two very
strong signals within 2 Khz on each side at the same time, they just
aren't effective on both.
Any input appreciated!
Thanks in advance es 73
