VHF-UHF Mountaintoppers, Rovers Asked to Observe Radio Quiet Zones

The National Radio Astronomy Observatory (NRAO) at Green Bank, West, Virginia, has asked that hams notify the facility if they plan to operate within 10 miles of either the Green Bank Telescope (GBT) or the Sugar Grove Research Station in Sugar Grove, West Virginia. The internationally renowned scientific research facilities are within both state and federal radio quiet zones. The West Virginia Radio Astronomy Zoning Act (WVRAZ) and the National Radio Quiet Zone (NRQZ) were established to minimize possible harmful interference to the Green Bank and Sugar Grove facilities. They are the only quiet zones of their type onEarth, and they offer the best protection of any US observatory from many forms of man-made radio frequency interference.

“Simply put, NRQZ coordination is required for all new or modified, permanent, fixed, licensed transmitters inside the NRQZ, as specified for federal transmitters by NTIA manual Section 8.3.9 and for non-federal transmitters by the FCC in 47 CFR Section 1.924,” the Green Bank NRAO said in an explanatory statement, “Only In Silence Can You Hear The Voice Of The Universe.”
