West Virginia Residents Fear ‘Quiet Zone’ May be Abolished

 

A national radio quiet zone was established in Green Bank, West Virginia in 1958 to house the world’s largest fully steerable radio telescope – the Robert C. Byrd Green Bank Telescope. The telescope successfully works due to the lack of interference from other transmissions. “Electrosensitives,” flocked to the area for more than 10 years. “Electrosensitives” are people who … [Read more...]

Low-profile Gasket Profiles Offer Snag-free Operation

 

Tech-Etch, Inc. introduces its new low-profile EMI/RFI shielding gasket profiles. These BeCu gaskets are offered in Stick-on, Hook & Stick-on and Clip-on mounting configurations. These gaskets are smooth to touch, require a low closing force, and are ideal for bi-directional applications. The Stick-on mounting configuration offers fast and reliable installation and can be … [Read more...]

Ham Radios Assist Police in Catching Indoor Drug Growing Operations

 

Ham Radio operators can assist police in catching indoor marijuana growers who are causing radio frequency interference. Operators can help by taking a radio and portable antenna into their neighborhood and using the radio to find the location of the often illegal plant being grown. This RFI can produce many different sounds. “It can be pops, it can be a buzzing sound, … [Read more...]

Illegal Radio Stations Cause Airplane Cockpit RF Interference

 

Four Chinese flights landing at Dalian Zhoushuizi International Airport early last month experienced radio interference in the cockpit from illegal “black radio” stations broadcasting nearby. The flights were forced to land despite their unstable communication systems, which were affected by electromagnetic interference. Black radio stations broadcast advertisements for … [Read more...]

Magnetic Resonance System Could Signal Breakthrough in Wireless Charging

 

WiTricity Corp. is developing a wireless charging system called “magnetic resonance wireless power transfer” that could safely transmit electricity to devices over a foot away from the source – even through solid materials, like walls. In light of the explosive popularity of smartphones, wireless charging systems have generated a lot of buzz recently; numerous companies have … [Read more...]

Proposed Ferris Wheel’s EMI Could Affect Aircraft

 

The Federal Aviation Administration released a Notice of Presumed Hazard against a proposed 443-foot high Ferris Wheel on the water front in San Diego, Calif. The FAA believes the structure will cause electromagnetic interference and affect navigation systems in aircraft. In the notice, the FAA stated if the wheel does not exceed 277 feet the government could issue a favorable … [Read more...]

Barrel Balloon Research Suggests Electromagnetic Waves Negatively Affect Earth

 

A NASA-sponsored research team from Dartmouth demonstrated that plasma waves pounding the planet’s radiation belts are responsible for distributing charged particles into the atmosphere. This type of solar activity can fluctuate and disrupt communication systems, GPS satellites, manned space exploration and power grids. The research team frequently studies the Van Allen … [Read more...]

‘Electrosensitives’ Congregate in Wi-Fi Quiet Zone in West Virginia

 

A national radio quiet zone in Green Bank, West Virginia, limits transmissions to protect a government telescope. This telescope, known as the National Radio Astronomy Observatory's Robert C. Byrd Green Bank Telescope, is the world’s largest fully steerable radio telescope. The telescope can pick up radio waves from space that are weak and difficult to identify. “The Federal … [Read more...]
