Created by Enrique Telémaco Susini, LOR Radio Argentina was the first national broadcast radio station in Argentina. It operated continuously from 1920 to 1997. == First broadcast == After returning to Argentina from Europe in 1919, the radio pioneer Enrique Telémaco Susini started working on the conversion of an old circus site into the ''Teatro Coliseo'' theater. Together with his friends Miguel Mugica, Cesar Guerrico and Luis Romero Carranza, he started planning for a radio transmission from there, strongly supported by the two Italian owners, Faustino da Rossa and Walter Mocchi.〔(【引用サイトリンク】title=Early History of Radio Broadcasting in Argentina )〕 During 1920, while the group was working on the project, news reached them of Marconi's successful broadcast of a concert in New York that had taken place on May 19. Even though it was somewhat of a disappointment that their broadcast would not be the world's first, the preparations continued at a rapid pace.〔 On August 27, they were finally ready. The theatre was showing the opera Parsifal by Richard Wagner. Susini and his coworkers had set up a 5W transmitter on the roof using a RS-5 Telefunken tube, operating in 350m,〔Revista Telegráfica, May 1923〕 along with a wire antenna connected to the dome on top of a neighboring building. To pick up the sound in the theater, they used a microphone originally designed to aid people with hearing loss.〔〔 Around 8:30 pm, Susini himself took the microphone and inaugurated regular radio broadcast service in Argentina with the words: The transmission continued for about three hours and was received as far as Santos in Brazil, where it was picked up by a ship's radio operator.〔 The number of listeners was limited, since the crystal set radios used at the time were rare and difficult to operate, requiring tedious fine-tuning of a lead glass crystal and installation of a wire antenna several meters long. But the newspaper La Razón published a raving review, and even president Hipólito Yrigoyen commended Susini and his group for their accomplishment.〔 (【引用サイトリンク】title= La primera transmisión radial del mundo se hizo en la Argentina )〕 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「LOR Radio Argentina」の詳細全文を読む スポンサード リンク
