Reading again these boards are more the basestation part of the system. But a freedv handheld is also something that can be VERY interesting.
As well as inventing a real solid open digital voice architecture made by hams for hams. Something that could work with open standards, like hamnet, SIP, ham calls, and a decentralized routing database to avoid any SPOF... sebastien Le 10/01/2018 à 14:11, Sebastien F4GRX a écrit : > have a look at the hermes lite 2 ( http://www.hermeslite.com ) > > It is in the process of being finalized, and can work with a raspi host. > > > I am also working on this: https://github.com/f4grx/hn70ap > > Not SDR, more SDFSK (with a si4463) > > some boards are being made right now. > > freedv software can definitely work on this. > > gps and battery can be added later in a v2. > > > dra818 is cool but you get the same problem as dstar and other stuff: very > suboptimal AFSK over FM... > > Sebastien > > > Le 10/01/2018 à 13:02, Adrian Musceac a écrit : >> Hi Jeroen, >> >> This is a very interesting project.
