とする電子同調受信機。 In an electronically tuned receiver that integrates an antenna and a high frequency circuit part and uses a capacitor variable tuning circuit as a tuning circuit, there is provided a means for applying a fixed voltage to the AGC circuit in a tuning operation mode and changing the tuning frequency, and a means for changing the tuning frequency for outputting an intermediate frequency signal. An electronically tuned receiver comprising means for detecting a maximum value to stop the change in the tuning frequency and to terminate the operating mode.
