CONELRAD (Control of Electromagnetic Radiation) is a former method of emergency broadcasting to the public of the United States in the event of enemy attack during the Cold War. It was intended to allow continuous broadcast of civil defense information to the public using radio or TV stations, while rapidly switching the transmitter stations to make the broadcasts unsuitable for Soviet bombers that might attempt to home in on the signals (as was done during World War II, when German radio stations, based in or near cities, were used as beacons by pilots of bombers).
U.S. president Harry S. Truman established CONELRAD in 1951. After the development of intercontinental ballistic missiles reduced the likelihood of a bomber attack, CONELRAD was replaced by the Emergency Broadcast System on August 5, 1963, which was later replaced with the Emergency Alert System on January 1, 1997; all have been administered by the Federal Communications Commission (FCC).
Unlike its successors, the EBS and EAS, CONELRAD was never intended to be used for severe weather warnings or local civil emergencies.
Conelrad was an American heavy metal duo from Pittsburgh, Pennsylvania. The group, consisting of Jeff Gretz (of From Autumn to Ashes and Zao) and Adam McGregor (formerly of Creation Is Crucifixion), formed in early 2001. They played at Mr. Roboto Project in 2003, and released a 7-inch record and a CD. In mid-2005, the duo went on a break. Sporadic activity since then has seen only two performances and the release of a 7-inch EP.
Their style has been described as a mixture of Carcass and Lightning Bolt, and features spoken word as well as shrieks; Pittsburgh Live referred to the band's music as "experimental lunacy".
