M17 - Digital voice mode

We are launching the documentation for the M17 project on the ICSSW.ORG website.

M17 is supported by the IARU as an open source and open hardware project. Mike OE3MZC, as chairman of the "Shaping the Future" working group, supports this project.

These pages provide a platform for documentation, discussion and shared test environments for M17

    M17 and CODEC2 are promising innovations for digital voice on VHF frequencies.
    Perhaps similar concepts can also be realized for shortwave!

    I have been using Codec2 on shortwave for several years. Works very well with FreeDV and also with SM1000 (module like M17 module, only for shortwave in mode 700D, 700E and 1600). Also tested several times via QO-1000, even in mode 2020 with better audio quality than M17.
