Jim,

I've played around with a few different things, but keep going back to 
MMTTY which is a free download.   Only RTTY, no other Modes.    It's far 
from perfect, and since JAWS  spells by letter, best suited for chasing 
DX or contests, not any sort of ragchew QSO.

I TX using FSK mode and turn the RX filter down to it's narrowest (250 
hz on the 590).     While I've never used it, I know the 590 has a data 
mode for SSB where you can set tight filters and then TX in AFSK using 
the  radio's soundcard.    With RX filter set narrow, you would tune 
slowley over the incoming signal untill  the screen reader  starts 
reading out something that makes sense.    Now you are tuned right on 
the other guy and can call him.
