Jim, great video. I have been playing with these telex devices for a few years now. If only we could decode the ADPCM CODEC they use, it would be cool to interface to Zello Bridge like what is done the JPS stuff.
They slightly tweek the standard voip codecs like g711 ulaw so it sounds garbled. They were smart in some ways making sure their stuff was proprietary. I had great plans too if I could crack that code. Lol.
