Event Description

The Oak Ridge Amateur Radio Club will be demonstrating how World War II-era military radio communications occurred during the Secret City Festival June 03-04, 2017. 

The event will include communications equipment as used by the US Army in the early days of the Manhattan project when they hit the ground running at

Site-X (Oak Ridge, TN) and Site-Y (Los Alamos, NM).


Radio communications were important from the beginning of the Manhattan project, before telephone and other permanent communications infrastructures were in place. All of the radio equipment is restored and operable and will be used on the air by Amateur (Ham) radio operators during the event.


In addition to the live demonstrations of two-way radio equipment, visitors will also be able to hear replays of historic radio broadcasts from WWII and the Cold War, including the announcement of the existence of Oak Ridge and the Manhattan project.

The replays will be transmitted through original home and military "morale" radios on display at the event, including some replayed from original radio station transcription discs. 


The exhibit will also include additional operating military radio stations including those from WWII, Korea, Vietnam, and the Cold War eras.  These stations will be operated as an FCC-authorized special events station, with a specially assigned call sign for Oak Ridge, N4M, and will communicate with other radio operators around the United States and the world.


Specially designed QSL postcards and certificates will be sent to Amateur radio station operators who make radio contact with the Secret City Festival event stations.
