There are no physical signs you’ve entered the National Radio Quiet Zone, a 13,000-square-mile area that covers the eastern half of West Virginia. But the silence gives you a signal. Somewhere around the Virginia-West Virginia state line, the periodic buzzes and pings of our smartphones stopped.
“Zero [service]. Searching,” said photographer John Poole, who traveled with me to the zone.
The ‘Quiet’ Zones
The circle represents the area protected by the West Virginia Radio Astronomy Zoning Act, which is the quietest part of the National Radio Quiet Zone, represented by the square.
Almost every radio station disappeared, too, except for Allegheny Mountain Radio, which broadcasts at a low enough frequency to avoid being banned.
“We didn’t realize the rest of the world was getting connected and staying connected constantly, via phones and computers and all that,” said radio host Caleb Diller, who grew up in Pocahontas County, W.Va. “So we were kinda back in time a little bit. We hadn’t progressed to that.”
The county still hasn’t progressed to constant connectivity. That’s because it sits within a zone designed to protect a sophisticated radio telescope at the National Radio Astronomy Observatory from interference. The Robert C. Byrd Green Bank Telescope is the world’s largest fully steerable radio telescope.
Radio telescopes work by tracking and reading the energy waves that come from stars or gases, but they have to be located in sparsely populated areas to avoid electromagnetic interference.
The Green Bank Telescope looks like a giant dish. It’s as tall as the Washington Monument and large enough to fit 2 acres of land in it.
“It’s a huge collecting area and it’s what allows us to see these incredibly small energies that we’re trying to study,” says Karen O’Neil, who oversees the site. “The types of energies we look at are less than the energy of a single snowflake falling on the earth.”
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.
“Because we’re looking at these very, very faint signals, we need to live in a very, very quiet area. In the same way where if you had an optical telescope, it needs to be high on the mountain away from other light,” O’Neil says.
So a federal quiet zone law and an accompanying state law — the West Virginia Radio Astronomy Zoning Act — combine to keep the area very radio quiet. No interference is allowed.
“We still have communications. I mean, it’s just … older. Dial-up telephones. We still have phone booths,” says Chuck Niday, an engineer for the National Radio Astronomy Observatory and a volunteer at Allegheny Mountain Radio.
Emergency communications are allowed in the zone, as is ham radio, a hobby among a set of West Virginians who chitchat or coordinate plans over their ham radios as they would their cellphones — if they had cellphones.
“Last year the big windstorm we had, we were without power for some days. And without a lot of communications. All the phone lines were down, so we had different spots around the county where we could talk from one end of the county to the other, and maybe relay about a store being open or somewhere having ice,” said Pat Schaffner, a Green Bank native.
To keep the zone protected from signals that could confuse the telescope, Niday and others from the NRAO drive the 20-mile radius around the Green Bank Telescope weekly, policing for possible interference.
