Call signs are frequently still used by North American broadcast stations, in addition to amateur radio and other international radio stations that continue to identify by call signs around the world. Each country has a different set of patterns for its own call signs. Many countries have specific conventions for classifying call signs by transmitter characteristics and location. The call sign format for radio and television call signs follows a number of conventions. All call signs begin with a prefix assigned by the International Telecommunications Union. For example, the United States has been assigned the following prefixes: "AAA"–"ALZ", "K", "N", "W". For a complete list, see international call sign allocations. ==Bermuda, Bahamas, and the Caribbean== Pertaining to their status as former or current colonies, all of the British West Indies islands shared the "VS", "ZB"–"ZJ", "ZN"–"ZO", and "ZQ" prefixes. The current, largely post-independence, allocation list is as follows: * Anguilla (in amateur radio "VP2E" prefix) * Antigua and Barbuda (uses "V2" prefix) * Bahamas (has the "C6" prefix) * Barbados (uses "8P") * Bermuda (also uses "VS", in amateur radio normally "VP9") * British Virgin Islands (for amateur radio uses "VP2V") * Cayman Islands ("ZF" for amateur operation, "ZF1" for Grand Cayman, "ZF8" for Little Cayman and "ZF9" for Cayman Brac islands. Visiting reciprocal for all islands is "ZF2")〔(【引用サイトリンク】url=http://caymanhams.org/ )〕 * Dominica (Commonwealth of Dominica, uses "J7") * Grenada (uses "J3") * Jamaica (uses "6Y") * Montserrat (for amateur operation "VP2M" prefix) * St. Kitts and Nevis (uses "V4") * St. Lucia (uses "J6") * St. Vincent and the Grenadines (uses "J8") * Turks and Caicos Islands (typically uses "VP5") 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「Call signs in North America」の詳細全文を読む スポンサード リンク
