[ICOM] AFSK RTTY with PROIII

[Phil Krichbaum]

Gary,
    Once I get the PBT down below about 900 Hz the RTTY reception is 
very poor. I thought that should work also. Strong adjacent signals 
killed me on RX.When using the RTTY position the filters are quite nice 
at 350 Hz and no adjacent strong signals wipe out of the RX. My FT1000MP 
does nicely but you need to use the IF shift on the AFSK frequencies. No 
such adjustment on the PROIII to my knowledge.
