Anyway, I looked at the connection design and noticed that in composite mode the antennas are not connected to the microcontrollers . One antenna has only an output connected, and the other one has nothing at all. Therefore, the aerials of the aircraft only catch radios and not any sources of communication, sound does not enter or exit. I hope I made the problem clear. just if I understood better in these things I would redo everything myself, but so I can only point out the possible problem. I hope you will notice my remark!
