FCC Radio Intelligence Division

Early Fixed DF

From its inception on July 1, 1940 until the end of World War II, the Radio Intelligence Division (RID) of the Federal Communications Commission intercepted hundreds of coded messages sent by German espionage agents all over the world and supplied the cryptographic laboratories of our government with these messages at their specific request.

In performing its patrol of the ether, RID located Nazi agents with their transmitters in the western Hemisphere, Africa, Europe and Asia.  It sent trained radio intelligence engineers to Latin American Republics to help clean out the infestation of German spies in those countries and trained representatives of those countries in radio intelligence techniques at its facility in Laurel, Maryland. 

RID located distressed aircraft lost in the black-out or having cockpit trouble by providing fixes to their radio signals and got them back on course to safe landings.

Another, rather unknown “first” for the RID was the fact that the movie produced about the RID called “Patrolling the Ether” was the first movie to be broadcast on television, March 10, 1944.
