Try using the MMTTY Program with the TS-870 and back off on the RF
gain just a bit then select FSK ant the 250 hz filter , I'm not a RTTY
expert but I know that this combination really works for me. I prefer to
use it when clg CQ with AFC off because most guys call dead on freq. The
only time that I copy anyone off freq is when I get to open up the Filter to
500 hz .
The 870 might not have been made for RTTY but IMO it is really great for
all 3 SSB,CW and RTTY.
