  • Automatic disabling of AFC/AFT controller during receiver circuit tuning
    Patent number: 4504973
    Abstract: An electromagnetic wave receiver system with an AFC/AFT controller and an adjustable tuner has the improvement whereby the AFC/AFT controller is automatically disabled when the tuner is being adjusted. The automatic disabling is implemented by a sensor which senses when the tuning means is being adjusted and which generates an electric signal when such adjusting is sensed. The electric signal is then applied to an OFF terminal of the AFC-AFT controller to thereby disable the controller when the receiver is being tuned.
