Abstract
A tuning control system of a radio receiver comprises a tuning voltage supply circuit which sweeps the received frequency by applying a variable control voltage to a variable reactance element of the tuning circuit and also stops the generation of the control voltage by means of a signal which is generated when a broadcasting signal is received. A memory for preset selection stores a counted value based on the received frequency signal and outputs this stored calculation value as a value corresponding to the desired broadcasting frequency. A digital comparator circuit compares the counted value based on the random receiving frequency signal and the counted output from the memory and generates a selection command signal for the tuning voltage circuit.
