Abstract
An aircraft radio comprises a receiver, an audio output, and a processing element. The receiver is tuned to a first radio frequency which provides a first audio signal and a second radio frequency which provides a second audio signal. The audio output provides an audio signal to a listening device. The processing element is coupled to a memory element and is configured to tune the receiver to the first radio frequency for a first time period, present the first audio signal to the audio output during the first time period, tune the receiver to the second radio frequency for a second time period to detect presence of the second audio signal, and present audio derived from the first audio signal to the audio output during at least a portion of the second time period.
