[Boatanchors] Morrow CM-1 CONELRAD Radio

[GRANT YOUNGMAN]

There’s nothing required to activate the relay than the station you are monitoring going off the air.  I suppose you can test by tuning to a station, and then disconnecting the antenna.

The idea was you tune to a strong non-Conelrad station.  If that station dropped carrier, the CM-1 alarm would sound.  You then had to tune to one of the two marked Conelrad frequencies (640/1240 KHz as I dimly remember), where actually emergency broadcasts would occur.
