A house across the street from the Green Bank Observatory operated a Wi-Fi network with the SSID "Screw you NRAO," an unsubtle middle finger from a resident who had grown tired of being told to turn things off. The Green Bank health clinic had Wi-Fi too. So did the senior center. "We're not supposed to," John Simmons, the Pocahontas County director of senior programs, told a Wired reporter, "but I think all that stuff about the noise levels is fabricated." In 2019, the Green Bank Interference Protection Group was detecting roughly 175 active hotspots within two miles of the observatory. The federal radio quiet zone is still on the books. Compliance, especially among locals who have lived inside its boundaries for generations, has become increasingly negotiable.

The Federal Communications Commission created the U.S. National Radio Quiet Zone in 1958 to protect the radio telescopes at Green Bank, West Virginia, and the antennas at Sugar Grove Station - then a U.S. Navy facility. The zone covers about 13,000 square miles centered on Green ...

Beginning in the 2000s, Green Bank attracted national attention as a refuge for people who claimed to suffer from electromagnetic hypersensitivity - a condition in which sufferers report headaches, fatigue, and other symptoms they attribute to ambient radio waves. Some moved to P...

The original protocol was that observatory staff would identify a source of interference, knock on the door, and ask the owner to turn it off. Compliance was usually voluntary. As consumer electro...
