Opulent Voice digital radio protocol is “Compressed but not compromised”.
A video of a complete over the air demonstration of the system, including satellite simulator, will be published earlier than planned. Thank you to all the volunteers making ambitious #hamradio things happen.
Opulent Voice sent over the air with real Barker code synchronization words and basic framing is working great in the PLUTO SDR implementation.
