You need a soundcard interface and software.  MixW2 is very good but the 
registration is $50.  MMTTY is free.  There is also TrueTTY ($39) but I 
haven't  any experience using it.

Another good freeware soundcard program is "Hamscope".  It has a very straightforward user interface and supports PSK, MFSK-16, RTTY, ASCII, Packet, and CW.

Hamscope is not as versatile as MixW, but it seems easier to use and it's genuine freeware.  Combine Hamscope with the freeware program MMSSTV, and you have a lot of functionality at a price everybody can afford.

Has anybody tried MFSK-16 on AO40?  It might work well when the Doppler shift is minimal.  MFSK-16 gives 100% copy of signals you can barely see on the waterfall and barely hear with your ear.  It should handle really deep fading.
