翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク QRP operation ： ウィキペディア英語版 QRP operation In amateur radio, QRP operation refers to transmitting at reduced power while attempting to maximize one's effective range. The term QRP derives from the standard Q code used in radio communications, where "QRP" and "QRP?" are used to request, "Reduce power", and ask "Should I reduce power?" respectively. The opposite of QRP is QRO, or high-power operation. ==Philosophy== Most amateurs use approximately 100 watts on HF and 50 watts on VHF/UHF , but in some parts of the world, like the U.S., they can use up to 1,500 watts. QRP enthusiasts contend that this is not always necessary, and doing so wastes power, increases the likelihood of causing interference to nearby televisions, radios, and telephones and, for United States' amateurs, is incompatible with FCC Part 97 rule, which states that one must use "the minimum power necessary to carry out the desired communications". The current record for a QRP connection is 1 µW for 1,650 miles on 10-meter band.〔According to Rich Arland, K7YHA (now K7SZ), in World Radio magazine (Feb. 1990, year 19, issue 89, pp. 46–47) http://www.naqcc.info/qrpworks.html〕 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「QRP operation」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.
