Radio Round the World

STUDENT at the Tungchi Engineering University, Shanghai, a Mr, Wang Fu-shih, says he has invented a portable television transmitter, which sends messages with complete secrecy. [°: is reported that the Belgrade Government has now definitely passed an order to the Marconi Company for a 40 kilowatt station to be built as early as possible. The entire broadcasting system is to be reorganised to bring it on a level with neigh_bouring States. OLDING that "wireless has become such a normal necessity of life that it has to be regarded just as essential as electric light," a Kosice, Czechoslovakia, court ordered a shopkeeper to remove the cause of interference to radio reception against which a resident complained. A MAN at Portland, Oregon, has built a wireless receiver for his bicycle, stringing the aerial between the handlebars. An interesting feature of the set is the manner in which the wire wheel-spokes, rotating between copper discs, serve as variable condensers, and tune the set into various stations, according to the speed of the cycle. HE postmaster at Tacoma, Colorado, claims that W9GNK has the poorest site in the world for radio transmission. It is situated at the bottom of a canyon 900 feet wide and 1000 feet deep, 300 feet from a 10,000 horse-power hydro-electric generating plant, and surrounded by tall pines, between two of which the aerial is suspended. On the east side of the canyon the wall goes up 6000 feet more. (TUNIS-KASBAH, a Morocean military transmitter, is on the air for ten minutes a day only to transmit meteorological information. It is reported that it is to be converted into a 60-kilowatt station. and will be connected by cable with the other local radio stations, EXPERIMENTS are being made in Sing Sing prison (New York) with a low-powered five metre transmitter and receivers for the use of warders when on their rounds. The receivers are carried like a military pack and their total weight is only six pounds. By this means it is hoped that warders will always be in totich with the chief warder’s office. HE Soviet is now considering the construction of a 1,000 kilowatt transmitter, having regard to the success achieved by the 500 k.w. station recently built at Moscow-Noghinsk, In addition to this super, Russia already possesses five others rated at 100 kilowatts, and fifty-six of power ranging from 2 to 25 kilowatts. In that country the State is the sole supplier of wireless receivers of which, according to the latest statistics, there are already three million in use. They are turned out at the rate of 600,000 sets per annum. The policy to be adopted in future will be that of erecting more powerful transmitters with a view to the making of simpler and less’ expensive ~ receivers, Bv doing so the State hopes to increase the production to some one and a-half million yearly. ,
