Morrow’s Conelrad monitor was a six-tube superhet that covered the broadcast band from 550 to 1750 kHz. When the monitored station’s carrier was interrupted, the CM-3 sounded a penetrating alarm but did not interfere with the amateur’s transmitter. It was powered by 117 VAC.
Available in "russet mahogany," "African ivory," or gray hammertone.
