Ken,
K0SM sent you a bunch of stuff about this. No one has made a good RTTY
setup really plug and play, and it takes messing with it a lot, and reading
a lot.
BUT -
In CQWW WPX, we ran N1MM, MMTTY AND 2 Tone using K3s and FSK (with the click
improvement FW). We found that 2 Tone outplayed MMTTY nearly all the time.
We ran FSK although we also have devices that remove bit jitter that one
normally gets with computer generated FSK. AFSK is probably the way to go
to start.
N1MM can display and run 4 decoders off the same audio stream. 2 MMTTY and
2 2-tone is what we did on all radios. Don't give up on it, keep plugging.
There's an N1MM tutorial on RTTY integration that's pretty good. You should
be able to google it.

that this doesn't work with Windows & 2 Tone and will produces an erratic

using FLdigi for transmit, a second RX window using 2 Tone for receive, and
possible a third RX window using MMTTY for receive, but as I said, I'm
pretty confused at this point.
