Brady O'Brien KC9TPA is a young ham who has been working with David Rowe VK5DGR, the creator of the open source CODEC2 low bitrate voice codec. In this TAPR talk he talks modem tech in SDR (a generalized way of saying that Gary doesn't understand it well enough to describe it).

He concludes by talking about the on-channel TDMA repeater project that David Rowe is working on using a VHF version of FreeDV and CODEC2. http://www.rowetel.com/
