Abstract

A reception section contains a resonance circuit which generates a resonance frequency, in accordance with a DC voltage, corresponding to a selected channel. The arrangement brings a received signal into resonance with the resonance circuit coupled between the aerial and mixing stage. A transmission section contains a resonance circuit, generating a resonance frequency, according to a DC voltage, corresponding to a selected transmission channel, bringing a transmitted, modulated signal into resonance. The resonance circuit is incorporated between the transmission PLL and the aerial.
