My sBitx V2 just arrived, serial # 0044, at first it wasn't working very well and was like 9Khz high in frequency but after pulling the latest updates all is well and I made my first contact and was given a "loud and clear" audio report without having asked for it. So far I'm very happy with it. One observation, all the receive audio is between 85-95% on the volume control, it is quite clear though. I'm sure it will only continue to get better with every update.
