using my TS480SAT with both CW filters, can get really narrow on PSK and still copy.
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?

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 Dave KB3MOW ------------------------------------------------------------------------------ No virus found in this incoming message.
