- Public Emergency Radio of the United States
The Public Emergency Radio of the United States was a communications system conceived during the
cold warera in the 1970s for use in case of a national emergency. The system included radio stations and a transmission network, to be activated when a nuclear attack was expected. The radio system was to broadcast on 167, 179 and 191 kHz in the long wave radio band.
Two transmission towers were built as a radio backbone:
*Cambridge Public Emergency Radio Tower was a 1260 ft. (384m) guyed radio tower at
*Ault Public Emergency Radio Tower was a 1260 ft. (384m) guyed radio tower at
The system was determined to be impractical and never implemented. The fate of the towers built for this system is unknown.
The 160-190 kHz range is currently used for
LowFERunlicensed, low power services.
