An apparatus for communicating using multiple channels. The apparatus includes a first radio receiver and a controller. The first radio receiver is configured to produce a first receive signal in response to a first radio frequency signal in a first frequency band. The controller has a first receive input for receiving the first receive signal, an audio input for receiving an audio in signal, a selector input for receiving a selector signal, an audio output for producing an audio out signal and a first transmitter output for producing a first transmitter signal. The first transmit output is configured for communication with a radio transmitter operable to transmit a second radio frequency signal in a second frequency band different from the first frequency band. The controller is configured to cause the audio output to produce the audio out signal in response to the first receive signal when the selector signal is in a first state and to cause the first transmitter output to produce the first transmit signal in response to the audio in signal when the selector signal is in a second state.
