Patent ID: 7483682

Claim:
An apparatus for communicating using multiple channels, the apparatus comprising: means for producing a first receive signal in response to a first radio frequency signal in a first radio frequency band; a processor circuit having a first receive input for receiving said 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, said first transmit output being configured for communication with a radio transmitter operable to transmit a second radio frequency signal in a second frequency band different from said first frequency band; and means for selectively causing said audio output to produce an audio out signal in response to said first receive signal when said selector signal is in a first state and for causing a first transmit output to produce a first transmit signal for use by a first transmitter, in response to said audio in signal, when said selector signal is in a second state and for causing a second transmit signal to be produced in response to said audio in signal when said selector signal is in said second state.
