Abstract
A circuit for terminating the signal seeking mode of operation of an AM receiver includes a comparator which responds to a composite signal comprising a broadband IF signal and the detected IF signal strength. A control signal is produced when the composite signal exceeds a predetermined threshold. The broadband component of the composite signal is effective as a blanking potential when the receiver is off-channel. A second comparator is utilized to establish local sensitivity so that local and distant sensitivity settings are not interrelated.
