I'm looking to change fldigi from using AFSK to FSK for RTTY with my Icom IC-7610.? Everything has been configured to work fine using AFSK.
?
While I'm still working on the FSK transmit connection using WinKeyer USB, I have a question about the waterfall display when receiving audio in RTTY mode on the IC-7610.? Instead of the display being centered at the 1500 KHz mark, it is offset almost 750 Hz up.? This is quite obvious when the 500 KHz filter is enabled on the Icom IC-7610 in RTTY mode.? Please see the attached (note there was no signal present on the frequency when this was taken).
?
What do I need to set to center the display like when I'm using AFSK?
