The only broadcast radio stations in the heart of the Quiet Zone are part of the Allegheny Mountain Radio network with just one station in the AM band, and several low-power FM stations.
The Robert C. Byrd Green Bank Telescope, or GBT, is the world's premiere single-dish radio telescope. It looks like giant dish. It's as tall as the Washington Monument and large enough to fit 2 acres of land in it.
The energy of Wi-Fi or cell signals can confuse or interfere with the telescope's readings — and it can trip the receivers at the government's nearby Sugar Grove research facility, which is also in the zone.
