Outside of these areas though, the restrictions are loosened somewhat because it is impossible to reduce radio interference to zero, when even turning on a gas car can emit interference. If a house seems to be using an appliance that is strong enough to interfere with research data, even something like a microwave, they have the authority to tell residents to turn it off. For example, the NRAO drives a van in the area around their Green Bank facility measuring the radio emissions from houses. The closer you get to either Green Bank or Sugar Grove, the more strictly the radio wave restrictions are enforced. It was chosen for the low population density the entire region only has around two thousand residents today. It was established in 1958 to protect the sensitive radio telescopes used at the US Navy Information Operations Command at Sugar Grove and at the National Radio Astronomy Observatory at Green Bank from interference. The National Radio Quiet Zone is a 13,000 square mile rectangle that covers portions of West Virginia and Virginia (and a tiny bit of Maryland).
This puts the observatory in Green Bank, West Virginia in the middle of the National Radio Quiet Zone.
The National Radio Astronomy Observatory in Green Bank wishes to look at those objects in space, but just like you wouldn’t see anything through a telescope with a flashlight pointed down the barrel, Radio Astronomy needs radio silence. They’re even coming down on us from the deepest reaches of space, black holes and galaxies. They come from your cell phone, your microwave, even your iPod. Here at Villanova, there are radio waves everywhere. There is no major residential area, no town center or local governing body there are barely even radio waves. It is not a county or a town or even a village it is a “census-designated place” with a population of 143 people as of the 2010 census.
