The Radio Amateur Civil Emergency Service (RACES) is a standby radio service provided for in Part 97.407 of the Federal Communications Commission (FCC) rules and regulations governing amateur radio in the United States.〔("Part 97: Amateur Radio Service" ). From American Radio Relay League web site. Retrieved Feb. 15, 2008.〕 The concept of a standby "Radio Amateur Civil Emergency Service" to replace the conventional "Amateur Radio Service" during wartime was developed in 1952 as result of input from the American Radio Relay League and the Department of the Army's Office of Civil Defense. During World War II, the Amateur Radio Service had been silenced and a new War Emergency Radio Service (WERS) had to be created from scratch in a process that took six months. The resulting standby RACES service was designed to provide a quicker and smoother transition in the event the President ever needed to silence the regular Amateur Radio Service again when invoking the War Powers Act of 1941. Despite four wars involving the United States since 1952, this has never happened. ==Activation== When so activated, the Radio Amateur Civil Emergency Service will consist of only those amateur radio operators who have previously registered with State and local governments to provide emergency radio communications for them in times of emergency. Other amateur radio operations might be suspended and operations under the RACES rules might be restricted to certain frequencies within the amateur radio bands. In addition to wartime communications, operations under the RACES rules can provide or supplement communications during emergencies where normal communication systems have sustained damage. It may be used in a wide variety of situations, including natural disasters, technological disasters, nuclear accidents, nuclear attack, terrorist incidents, and bomb threats. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Radio Amateur Civil Emergency Service」の詳細全文を読む スポンサード リンク
