とを特徴とする受信機故障検出回路。 In a duplex receiver, the level difference between the limiter output signal obtained from the first receiver and the limiter output signal obtained from the second receiver exceeds a specified value. In the monitoring circuit that detects an abnormality, an alarm is output under an AND condition of an OR output of a squelch signal obtained from the first receiver, a squelch signal obtained from the second receiver, and the abnormal signal. A receiver failure detection circuit characterized in that:
