640/1240 CONELRAD.
The idea was that all local radio stations in a given area move to these frequencies and power down to maybe a couple hundred watts, and then hand off the program to each other over a loop every 30 seconds. The idea was to confuse enemy bombers and keep them from getting a beam on any one signal.
ICBM’s made CONELRAD obsolete.
Wasn’t the acronym for “Control of Electromagnetic Radiation”? My parents had a ‘63 Mercury Meteor that had the CONELRAD markings on the radio dial.
Hmmm. I didn’t remember the hand off part. I do remember every radio dial had 640 and 1240 marked with a CD triangle and circle.
And had they not, GPS would have.
