What is the function of the audio control panel identifier select switch set to the R position?

When the audio control panel identifier select switch is set to the R position, it is configured to receive only voice communications. This setting allows the pilot to listen to normal voice transmissions without other signal types being processed, ensuring clear communication in the cockpit.

This is particularly important during operations where voice clarity is essential, such as in busy air traffic environments or during instruction and training scenarios. The switch effectively filters out Morse code signals, focusing solely on voice communication, thus enhancing the pilot's ability to communicate effectively with air traffic control and other aircraft.

Understanding the specific functions of the audio control panel is crucial for efficient operation and safe communication within the T-6 cockpit environment.
