I have been checking out new HF digital technologies and ran across FreeDV, which is designed for Digital Voice for HF.
Previously, I had only read about Digital Radio Mondaile (DRM) for digital voice or DStar. Thus FreeDV is new to me. At 1100 Hz bandwidth, it seems to be efficient compared to others.
What surprises me is that I find little about this new mode except for this website. http://freedv.org
Does anyone have any experience with FreeDV?
