Here is a nice video with Paul ZL3IN and Bruce Robertson VE9QRP have a nice conversation using codec2. This is what I think Amateur radio is all about. Open source and moving in the direction we need. Check it out and see what you think. I think this a better route than D-Star. I have never embraced D-Star as a true Amateur Radio mode. Should I look into it more or stand my ground on D-Star. Watch the video and then let me know.
