Van Eck's research paper has no references pre-1965, which I presumed he would have used had it available. Can you 
provide a reference to the original research from the 1950s?


/The Ultimate Spy Book/, H. Keith Melton, London, 1996. p. 84. /[Excerpt]/


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.
