Hi Gerhard, It's currently in Linux command line form, take a look at:
https://github.com/drowe67/codec2/tree/brad-2020 "FreeDV 2020 Support..." section To make it run over a real radio you would need to pipe audio signals to/from a sound card (or SDR). It can handle a 10dB SNR slow fading channel or without fading (like a satellite channel) down to 4dB SNR. Brad and I are progressing this branch (and the associated https://github.com/drowe67/freedv-gui) daily. Feel free to email me if you get stuck.
