HF Digital Voice has been around a while, but it hasn't really caught on the way D-STAR has on VHF/UHF. That could change with a good, open-source codec - CODEC2 - that's on its way. In this forum, Mel Whitten K0PFX reviews the various options for HF Digital Voice, from AOR's hardware modems to the sound-card modes.
In our Poster Frame, Mel is joined by CODEC2's author David Rowe VK5DGR. David had his own talk on CODEC2 at the 2011 DCC (available at www.ARVN.TV), and he also made the keynote talk at the Saturday night banquet, where he spoke about a service project he's involved in called The Village Telco (and yes, it's at www.ARVN.TV as well).
