One of the Few Places Left Where Wireless is Regulated

In the remote hills of Virginia and West Virginia, a 13,000-square-mile area is one of the few places in the US where wire-less communications are not allowed.

It's called the Quiet Zone.

Astronomers seeking to learn about the universe by picking up electronic signals from space had a problem with electromagnetic interference caused by radios and whatnot on Earth even before the FCC created the Quiet Zone in 1958. Today, cell phones and other digital devices massively compound the problem - which means the Zone must be constantly patrolled to make sure no one in the area is using unauthorized gear.

The Quiet Zone is home to the National Radio Astronomy Observatory's Green Bank Telescope, a fully steerable 16 million pound Goliath that captures radio waves from space with the precision of a Swiss watch. It's capable of receiving the quietest radio signals in the universe. But it can't do that if there are other devices broadcasting in the same frequencies - even signals too faint to interfere with anything else. The telescope is so sensitive that only diesel-fueled cars are allowed on the property because even spark plugs emit radio frequencies that can wipe out the signals from space. The Zone also provides electromagnetic protection to a secretive Navy research facility at Sugar Grove that monitors communications here on Earth.

Join Ziya Tong for a guided tour of one of the world's most unwired places. And check out the web original article, Electromagnetic Traffic Jam, to find out how the electromagnetic noise generated by cell phones, laptops and all those other gadgets we can't live without are affecting all of us.

Are there any hotels in the area? I think I found the perfect place to get away from work! No laptops, computers, cell phones, radios, television, nothing. How awesome is that? It is a little close to the NSA, but the peace must be like a slice of heaven on earth!

You got the weight wrong. It weighs many times what you listed. Please correct this.

I would like to know if Wesley Sizemore has a email address, whould like to ask him a question about his hat.

Too bad Electro Magnetic Interference in the “optical” range of frequencies can't be enforced as stringently as “radio” in the Quiet Zone to improve optical astonomy - not to mention reduced energy waste needlessly lighting up the night sky.

17,000 pounds?

Probably more like 17,000 tons, or maybe 170,000 pounds.

I mean, look at the size of that thing, and figure that a city bus weighs 35,000 - 60,000 pounds.

Awesome show though.

the weight is 17,000,000 lbs, sizemore mentioned the weight on the green bank telescope video link.

Go and see it and learn more. I lived there and it is awsome!!

Radio communicatons monitoring ("scanning") is my hobby, and I found this to be a very interesting story. I'd like to learn more about how these restrictions (frequency, power, etc.) affect public safety agencies and other potential users of land mobile radio equipment in the National Radio Quiet Zone. That's one big chunk of real estate.

P.S. - I want Wesley Sizemore's job when he retires! He sure seems to have a lot of cool "toys" at his disposal.

I wonder if the FCC will be promoting Broadband over Power Line (BPL) in the radio quiet zone as they stupidly have done elsewhere. Essentially, BPL uses radio frequency signals on your power lines to provide internet access.

Unfortunately, they forgot that the unshielded power lines then become giant antennas broadcasting “radio smog” across the entire radio spectrum, obliterating essential radio communications in many bands and services. Cable, fiber optic and satellite already provide lots of broadband access without causing any radio interference, so BPL isn’t needed.

For more information as to how you can prevent BPL interference in your neighborhood, see

To Antimidas:
Check out Snowshoe Mountain- www.snowshoemtn.com -we stayed there and it was wonderful. Only 15 miles from the telescope and in the "Quiet Zone". One of the most peaceful places on earth and john Denver was right---"Almost Heaven, West Virginia"!

I apologize for this being so completely off the subject. but can anyone tell me the weight of the orion/ares I spacecraft that is planned to carry the first manned team to mars. I am trying to estimate how powerful an ion rocket engine would have to be to propel this craft at 1/10th of a G and the amount of reaction mass necessary for a constant thrust four week round trip as suggested by Robert Heinlein. from my google search I estimated its mass at 125 metric tonnes.

This is a nice little town nearby called Cass. It is a state park and they rent old houses by the day, week or month. There are also hotels nearby in Marlinton, Snow Shoe Ski Resort, Bartow, Boyer and Elkins. Also see the NRAO Green Bank for other local attractions.

Since I have no training in physics or electronics, I was happy to find insight into a possible reason for some force, not a sound or vibration, that seems to be a complete surround for the last 15 yrs. It started out as a pulsating EMF? and got stronger over the years to where it will either keep me awake or awaken me at times. Sometimes it's stronger than other times. It goes through any ear plugs and throughout the house. Drives me crazy! Could someone please tell me if it is from cell towers, GPS, or something else & give a clue as to how I can avoid it? I'm also very sensitive to computers, esp. laptop and the old-fashioned ones. (I use dial-up flat screen.) We live in the countryside, although the city is encroaching. Thank you anyone. K. Fox

For kc4myv: Access to the radio spectrum is a privilege, not a right. Use of the radio spectrum is governed by international and national law.

Kathy,
google "electrohypersensitivity" (EHS)...you're not alone...there are numerous studies on emf/emr non-thermal effects on biological systems.

Hi! thank you EMF sensitive-esplly cellphones & so glad to hear info & Lord knows have been wanted to go SNOWSHOE area & now finding out why!!! Thanks again.

To Kathy and anyone else hearing the hum it's not only sensitivity to electromagnetics. It is The Microwave Auditory Effect except today it's not just buzzes and clicks. It's the pulsed electromagnetics of the new telecommunication towers. Let's hope we can find those quiet zones, not only astronimers need quiet.

wow

All of the people in the surronding area will not agree with how cool this is. Next thing you know we won't be able to listen to the radio driving through that area. It's a joke in my opinion.
