ciao Claudio.
finche' ha trasmesso (1992) era 17442 Hz.

The Yosami Radio Transmitting Station using Very Low Frequency (17.442kHz) was
completed in March 1929 at Yosami village (Kariya city) near Nagoya. It was built for trade and
governmental communications between Japan and European countries. Long wave and large
power were needed for long-distance wireless communications in those days. The huge
machine-sender, which was one of the biggest ones in the world at that time, was designed by
Telefunken and manufactured by AEG of Germany. The transmitting system composed of the
induction type HF generator, with output power of 500kW and frequency of 5.814kHz, and the
frequency tripler. Its first destination was Warsaw, Poland on April 15th, 1929, and next was Berlin,
Germany (Nauen Radio Station) on 22nd. Yokkaichi Receiving Station had already been opened in
March 1928, two-way communications through 80,000 - 10,000km distance with European
countries became possible by the opening of Yosami Radio Transmitting Station. The YOSAMI
came to be known as one of the largest wireless stations in the world.
