THE WIRELESS WORLD.

RADIO NEWS AND I NOTES. Not less than twenty-five per cent, of the population of Czecho-Slovakia are wireless listeners, the number being 284,432. The proportion of crystal set users is estimated, to be sixty-seven per cent. This year the National Radio Exhibition at Olympia, London, will be opened on September 19, and will elose on September 27. A novel feature, and a very successful one, will be repeated this year in the shape of demonstration rooms, and it is expected that some twenty-two will be required. This is evidently for the tuning in of outside stations and/or of reproduction on gramophone records. A super power station is being established at Budapest, over 100 kilowatts to be the energy used. To supply dead areas a number of 19 kilowatt stations will also be supplied. The provision of a mechanical millItary band for drilling and marching purposes is the latest task to be entrusted to the Radio Corporation of America. According to a Washing ton correspondent, says the “Wireless World,” the apparatus is to bo tried cut on the 3rd: Battalion of the U S. 12th Infantry. The entire “band” will bo carried on a truck and the music will be supplied from suitable amplified gramophone records. For the first time in the history of American radio, a tax is to be levied on wireless receivers, South Carolina 'being the State to introduce this daring experiment. The tax amounts to approximately two shillings annually on re.ewers valued at fifty dollars, with proportionate increases according to value, ’t is stated that the proceeds will bo devoted to hospitals. A few weeks ago there was an announcement in the news cablegrams that the Marchese Marconi had, from his yacht, the Electra, and whilst in the Mediterranean, switched on the power at the opening of a show in Sydney. This was hailed as a proof that electrical energy could be transferred a long distance by wireless. Marconi himself has disclaimed these extravagant reports. the matter is that an ordinary wireless signal was used to trip a fairly delicate relay or similar type of apparatus, which, in turn, merely made the necessary connection to switch on the power in Sydney.
