THE THING

In the early 1950s, a Soviet listening device was found in the American 
Embassy in Moscow. This came to the attention of the world when it was 
displayed at the United Nations by the American ambassador in May, 1960. 
It was a cylindrical metal object that had been hidden inside the wooden 
carving of the Great Seal of the United States -- the emblem on the wall 
over the ambassador's desk -- which had been presented to him by the 
Soviets.

The Great Seal features a bald eagle, beneath whose beak the Soviets had 
drilled holes to allow sound to reach the device. At first, Western 
experts were baffled as to how the device, which became known as The 
Thing (illustration omitted here) worked, because it had no batteries or 
electrical circuits. Peter Wright of Britain's MI5 discovered the 
principle by which it operated. MI5 later produced a copy of the device 
(codenamed SATYR) for use by both British and American intelligence.

/How the Thing Worked:/

A radio beam was aimed at the antenna from a source outside the 
building. A sound that struck the diaphragm caused variations in the 
amount of space (and the capacitance) between it and the tuning post 
plaste. These variations altered the charge on the antenna, creating 
modulations in the reflected radio beam. These were picked up and 
interpreted by the receiver.
