Digital Voice Modes Explained

Below is a link to a YouTube video from Ham Radio Now dated March 3, 2015. This video features an interview with the inventor of FreeDV, a digital voice mode we often discuss and operate on the ATV Digital Modes Net.  The video runs about 70 minutes, but if you are at all interested in digital voice, it is extremely interesting. They discuss the current “state of the art”, new hardware products, and research into new VHF/UHF modes. The last 20 minutes or so are particularly interesting as they discuss a new implementation of TDMA in ham radio VHF/UHF communications that has the potential for completely redefining how repeaters work.
