It was built for trade and<br />governmental communications between Japan and European countries. Long wave and large<br />power were needed for long-distance wireless communications in those days. The huge<br />machine-sender, which was one of the biggest ones in the world at that time, was designed by<br />Telefunken and manufactured by AEG of Germany. The transmitting system composed of the<br />induction type HF generator, with output power of 500kW and frequency of 5.814kHz, and the<br />frequency tripler. Its first destination was Warsaw, Poland on April 15th, 1929, and next was Berlin,<br />Germany (Nauen Radio Station) on 22nd. Yokkaichi Receiving Station had already been opened in<br />March 1928, two-way communications through 80,000 - 10,000km distance with European<br />countries became possible by the opening of Yosami Radio Transmitting Station. The YOSAMI<br />came to be known as one of the largest wireless stations in the world.<br /><br />73 de Mauroi Bernardetto IK1WVQik1wvqhttps://www.blogger.com/profile/03601832858440471057noreply@blogger.comtag:blogger.com,1999:blog-8617661313289445510.post-20176179496973443172015-09-14T18:38:52.902+02:002015-09-14T18:38:52.902+02:00Ciao Mauro .
