considering the AAT prices, I was looking for some DYI project and found it. What i like is you are working in both RX/TX using cheap arduino, after read all posts i can see the evolution.
I can not understand what is the deal using video or audio, I mean both are signals using the same equipment video transmitter, the error checking makes the difference when using the audio.
I have dragonOSD i read that video has telemetry already, however after years no development in this matter so It will be great use this one and use the power for directional antennas. Thanks for sharing..
