翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク National Traffic System ： ウィキペディア英語版 National Traffic System The National Traffic System (NTS) is an organized network of amateur radio operators sponsored by the American Radio Relay League for the purpose of relaying messages throughout the U.S. and Canada.〔ARRL Public Service Communications Manual () 2 March 2010〕 During normal times, these messages are routine greetings ("Happy birthday Aunt Mary") and keep the system well oiled and the operators trained so that everything works when needed. When there is an emergency or disaster NTS works closely with the Amateur Radio Emergency Service to provide emergency communications. The most common type of disaster-related messages are "health and welfare" inquiries and notifications into and out of the area affected by the disaster. In time of disaster, it is easy to expand the system by simply creating additional meeting times for the nets with high volume, or by setting up a specific "trunk line" between two points. ==History== Traffic passing by formal relay (via amateur radio) originates from the founding of the American Radio Relay League. The NTS as it exists today was first outlined by George Hart, W1NJM (died 24 March 2013) in "New National Traffic Plan: ARRL Maps New Traffic Organization for All Amateurs" as part of the September 1949 issue of QST. While traffic passing between amateur radio operators was nothing new, Hart's system extended coverage of traffic capability in a uniform manner across the U.S. and Canada, creating formal section and area nets devoted to handling NTS-organized traffic.〔"National Traffic System Developer George Hart, W1NJM", Retrieved 11 July 2013 from http://www.southgatearc.org/news/march2013/george_hart_w1njm_sk.htm#.Ud4wrOH0HpQ〕 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「National Traffic System」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
