The Pilot Client will send any frequency changes on COM 1 or COM2 to the voice client. The Pilot Client will also send audio panel changes to the voice client. This includes changing the transmit radio as well as enabling listening on COM1 and COM2. Integration with X-Plane requires that your aircraft be properly supporting the common X-Plane datarefs for the radios. It also means that you need to have the audio panel setup properly. As an example, the mic selected for the radio you want to transmit on and the audio monitor selected for the radios you want to monitor.
Some aircraft do not have a visual means to change which radio you are transmitting on. If you are flying an aircraft that has this limitation you can still adjust which radio is being used for transmitting by mapping keys or joystick buttons to the following two X-Plane commands:
If you encounter an aircraft that does not accurately model the audio panel by properly maintaining the above datarefs please let the aircraft designer know about the problem. For your convenience we have incorporated a command that will toggle between transmitting on COM1 and COM2:
The toggle command simply executes one of the two built-in X-Plane transmit_audio_com(x) based on the state of the audio_com_selection dataref.
