Radio receiver monitoring and testing apparatus
TL;DR: In this article, an off-frequency monitor is attached to a radio receiver to monitor and test a detected intermediate frequency signal and audio signal from a demodulator portion of the receiver to determine whether a transmitted radio frequency signal is within frequency tolerances and modulation limits and to provide an alarm, either visual or audio, when the limits or tolerances are exceeded.
