FreeDV Demo Video

This is a QSO between Tampa, Florida and St. Louis, Missouri, using Codec2 driving a 50 watt SSB transceiver. Watch the waterfall display when the operator switches to analog SSB - the SSB bandwidth will be about 3 times that of the digital QSO! This demo is of the Windows version of FreeDV.

Also note the diagonal black streeks across the waterfall display. That's fading, probably from two reflections arriving out of phase with each other. The ID on the bottom is coming in during silent periods between words.
