摘要： A radio receiver and rebroadcaster comprises a first receiver for FM Radiosignals, a frequency synthesizer and microprocessor controller, a subcarrier select filterand amplifier which filters out all signals from the composite baseband signal except fora desired subcarrier signal, a second receiver which converts the subcarrier signal to arecovered audio signal, a lowpass active filter which filters the recovered audio signal, avaractor modulator and rebroadcast transmitter which receives the filtered audio signaland varies the frequency of the signal emanating from the rebroadcast transmitterproportional to an audio wave form, and a band selector which is controlled by themicroprocessor controller for controlling gain in the varactor modulator and forselecting a rebroadcasting frequency. The microprocessor controller provides tuninginformation to the frequency synthesizer, and the frequency synthesizer cooperates withthe first receiver to provide a composite baseband signal. The subcarrier signal isselected by the microprocessor controller.
