Hi Adrian, I've just compiled up the "next" branch and am just trying to figure out how to set it into Codec2 mode and, which mode. I note on your video, you are using the "QPSK 10K" mode. In my compiled version, I see the "BPSK 1K (700B)" mode, can we have the 700D mode as this is becoming

Hi, I made a clone of Gqrx with transmit support for digital and analog voice, video and IP data. You can see it in action here: https://www.youtube.com/watch?v=9bxorlma7QU What I'd like to know is if people are interesting in transmitting and receiving FreeDV with SDR hardware. I'm looking at
