The SCR-510 Radio Set was the primary small unit communications system used during World War Two. This unit could be
mounted in a variety of different vehicles. This system was used for communication over a range of approximately 5 miles. The
BC-620 Radio is a crystal controlled radio that operates in the 20.0 - 27.9 Megacycle range (or Megahertz/MHz today).

CIPHER MACHINE
M-209 Cipher Machine, above photo.
The M-209, originally titled "Converter", was one of the first U.S. Military cryptographic or "code" machines. The M-209-B,
shown above, is complete with the canvas carry case and manual. The M-209 was the U.S. version of the German "Enigma"
cipher machine. It used a simple, but very hard to break, wheel system to change one letter to another. Once the conversion
was completed, the radio operator would "tap" the message out via Morse code or by plain speech. The recipient would then
set the same code into their M-209 and retrieve the message. The U.S. Signal Corps used a large amount of cipher equipment
during World War Two, but very few survive today.
Engine Radio Suppression Boxes, left photo.
These boxes were mounted over the Coil, Distributer and all four Spark Plugs. These boxes added additional radio
suppression for vehicles with radio systems. These boxes were added at the depot level when radio systems were installed,
and not in the factory. This system is believed to have been implemented during the middle of 1943.
