The National Radio Quiet Zone

The National Radio Quiet Zone is a 13,000 square mile of West Virginia where all EM noise is kept out. Recently the man in charge of keeping the zone quiet went as far as replacing an electric blanket for a couple that lives in the zone because its wires were worn down and creating radio noise (Source, WIRED Magazine, Feb 2004). Having just saw an article on the Quiet Zone I thought some at ATS may not be aware of it.

The Zone openly is to helps support a National Radio Telescope that requires no ground noice to function. However, the telescope is toward the edge of the quiet zone and I think it entirely possible that other governments radioscopes or devices lay within the quiet zone.

More information and a map of the zone can been found here...

Very interesting. Obviously you cannot prevent radio waves from interfering but you can limit the amount of radio energy in the area.
