"Multi-tone 63" -- description was attached there in the announcement.
Instead of the stand-alone implementation (that was announced), you
should try gmfsk: http://gmfsk.connect.fi/
You need an SSB radio, and decently precise sampling rate in your
audio card. (better than 10^-4 precise.)
And some sort of PTT command interface circuit. Possibly galvanic/opto
isolation in between the computer and radio.
