Greetings, Many thanks to all who responded. Gene, N7YW, had a simple solution. First, change the "SET MODE" command in the ICOM 746.rig file from "0600FD" to 060002FD". Like I said in earlier posts this forces the IC-746 to select the appropriate mode with a "narrow" (actually "medium") filter. The second part is to tell the IC-746 which filters to use for each mode and which filters to use when the "Filter" or "narrow" mode button is pressed.
I set CW narrow to use the 500 HZ filters and USB/SSB narrow to use only the 2.4 filters. Now when DX4WIN sets the mode to CW, it automatically goes into "narrow" mode with a 500 Hz filter. When USB/LSB is selected, the front panel shows "narrow" mode, but still uses only the 2.4 filters. It works for me since I don't have or need to use any narrow filters on SSB. The long-term solution will require Paul to rewrite the rig control code to allow filter selection. Perhaps something like CW, CW-N, SSB, SSB-N could be used to toggle the filters...
