On 6 October 2017 Prof. Nishihara joined a visit to Yosami Radio Transmission Station Memorium Museum in Kariya city, which was organized by IEEE LMAG-Tokyo. The transmitter is actually a big generator rotated by a DC motor at 1360 rpm. The DC was generated by a DC generator rotated by an induction motor driven by the commercial power supply. Generated 5.814 kHz was tripled to 17.442 kHz and fed to the gigantic antenna system of eight 250m-high steel towers. Now only one tower shortened to 25m remains. The station was established in 1929 and used for communication with Europe and submarines.
