SmartMic

See http://www.rowetel.com/blog/?p=3125 .

This could be a killer app for amateur radio: Digital Voice (DV) without the need for a PC. It consists of a board that goes between the mic and rig and the rig and LS.

DV in the end is a 1.25kHz wide 16QPSK signal able to work with very low S/N ratios and low power transmitters.

After all said and done it is all open source.
