I saw it and it looks very promising. With the audio-performance of my video-tx I was also not very happy, that's why I asked for teletext. Do you think there would be some timing/resource left in the existing code to implement the audio modem or should one use an independent controller? I think it would be enough to transmit the two necessary angles plus a checksum only.
The code for the audio-modem shouldn't take up much cpu-time. The general idea and code for bit-sending have been made by Melih from Flytron, but it have been more or less rewritten to allow serial-receiving (or other tasks) while sending telemetry. As I never implemented it I can't say anything for sure, but my guess is that no extra controller is needed.
