Matt,
I think there are some web sites with audio clips of each mode, but
sorry I don't have a link. A google search might kick up something.
In MMTTY you can play RTTY audio files. I don't think they come in the
basic download. If I remember, they are on the download site and you
get them seperatly and install them as directed in the instructions.
You can play them with no need to be connected to the radio. You can
hear what RTTY sounds like, and see if your screen reader can speak what
is coming into the receive window.
You will hear psk between 14.070 and 14.073 or 21.070 and 21.073.
RTTY around 14.085, 21.085 Higher and lower as the band fills.
The RTTY North American QSO Party is on Saturday starting at 1800 utc
and there should be a lot of activity (depending on band conditions).
Digipan only does various flavors of psk (31, 16, qpsk, etc) and receive
pactor.
MMTTY is RTTY only. If you try and decode the wrong type signal, you
will just get garbage. There is a boatload of digital software out
there, don't know if anything will auto detect the mode, but that would
be pretty cool.
Sounds like you are serious about this. Good luck. Read the docs for
the software. A lot of it will seem confusing, but just take your
time. Like the old line about how to eat an elephant: "One bite at
a time".
