Mobile citizen band transceiver control unit with an audio frequency apparatus
First Claim
1. A vehicular communication system, comprising:
- a communication radio transceiver including transmitter circuitry responsive to channel selection signals for transmitting radio signals on selected channels determined by the channel selection signals, and receiver circuitry responsive to the channel selection signals for receiving and detecting radio signals on selected channels determined by the channel selection signals, said communication transceiver being mounted in use at a position remote from a vehicle operator;
a broadcast band radio receiver having an audio amplifier output circuit for amplifying detected broadcast band radio signals, said broadcast band radio receiver being mounted in use at a position proximate a vehicle operator and remote from said communication radio transceiver;
a control unit including means for applying the detected radio signals from said communication radio transceiver to said audio amplifier output circuit of said broadcast band radio receiver to be amplified, electronic switching circuit means operable for inhibiting said audio amplifier output circuit of said broadcast band radio receiver from amplifying detected broadcast band radio signals so as to amplify the detected signals from said communication radio transceiver without interference from detected broadcast band radio signals, channel selecting means for developing the channel selecting signals for selecting the channels on which said communication radio transceiver operates, and channel indicating means for indicating the channel of said communication radio transceiver selected by the channel selection signals, said control unit being mounted in use at a position proximate a vehicle operator and remote from said communication radio transceiver; and
a connecting cable for connecting said control unit and said communication radio transceiver for applyinng channel selection signals from said control unit to said communication radio transceiver and for applying the detected signals from said communication radio transceiver to said control unit.

Abstract
A mobile citizen band transceiver (hereinafter referred to as CB transceiver) control unit with an audio frequency apparatus includes a radio receiver, an instrument panel at which the radio receiver is installed in an in-dash mounting, a channel selecting knob for the CB transceiver, a channel indicating member, and a CB transceiver unit including electrical circuits for receiving or transmitting CB signals, except at least the channel selecting knob and the channel indicating member, and a connection cable for connecting the channel selecting knob and channel indicating member to the CB transceiver unit. The channel selecting knob and the channel indicating member are built into the radio receiver, or alternatively located adjacent to the radio receiver. The transceiver unit is installed at any desired location other than the instrument panel.
