変調度補正回路。 An audio input circuit having an electronic volume is connected to a variable control oscillator of a phase lock circuit that determines the modulation frequency of the radio, a memory section is connected to a modulation adjustment volume connected to the electronic volume via a switch, and the modulation adjustment is performed. The variable control oscillator is modulated within the standard by changing the voltage of the volume, and the optimum operating conditions of the electronic volume obtained at this time are stored in the memory section, and the electronic volume corresponding to the frequency used by the variable control oscillator is stored. 1. A modulation degree correction circuit within a VCO band, characterized in that the optimum operating condition of the variable control oscillator is obtained from the memory section signal to operate the variable control oscillator.
