Radio Round the World

A POWER of at least 110 kw. will. be used for Budapest’s new broadcasting station. It is proposed to pro-: vide for any remaining "dead" areas’ by the use of 19 kw. relay stations. * "| m PORTUGAL, having no broadcasting Stations to maintain; has gencrously decreed that its people may listen-in-to other countries-free of tax, provided their aerials do not cross roads ang other public property. eR * A SPECIAL license to establish a 100-watt shortwave station ias been granted to a prominent motion picture company in Hollywood. It is to'be used for directing aeroplanes fea--turing in an aviation picture now in the course of production. Xe _* oe . ; HE Paris central fire station is now in possession of a transmitting .set which enables it to advise all fire stations in the neighbourhood of any diangerous fire, as well as the Prefecture of Police, in order that a force of police may be sent to the spot. . . e = ok S an example of the growing tendency toward an alliance of gramo phone and radio interests, it is significant that the German Radio Exhibition, which takes place from August 22 to 31, will this year for the first time be held in counection with tha Talking Machine and Record Pxhibition. % a Bd Sa result of an official inquiry it has been established that there are 2228 schools in France provided with wireless sets, without counting private sets owned by the masters, which are often used for the benefit of the pupils. It is universally admitted that useful additional instruction can be given in an interesting manner by this means. %& 3h * MIS year’s National Radio Exhiltion at London. will commence on September 19. The introduction of demonstration rooms, which was the most successful innovation of last year's show, will be repeated. Demonstrations will also be permitted on the stands, with loudspeakers connected to a common output. * : = O prevent digging up the streets over a considerable area, a frame radio aerial. and an instrument resembling a portable wireless set are being used in London to locate underground water mains. When the aeriai is directly above the pipe the instrument transmits a buzz which is heard by the operator through earphones. x * x . . ° NEw ZEALAND listeners whose entertainment is marred by electrical Interference will be interested to learn that a device for locating the source of such disturbances has been per-

fected by two American engineers. ‘The instrument has the appearance of an ordinary portable receiver, and includes an oscillograph . which _ records the wave-form of the intruding signal. The. inventors hope to supply an ‘interference detector ‘to ‘every munit 4 ot uuthority in the United States. "f *. [m, * ROUBLE has arisen’ in Americaconcerning. the inclusion ofa state. ' ment in the census "forms: "IIave’ you a radio?’ If radio sets are included, remark those protesting, why not pianos, yacuum-cleanets, washingmachines, and a number of other do--mestic appliances whose manufacturers would welcome statistics? It is understood that radio was piloted through the census’ mesh by infinence not un-. connected with the’ Radio Manufacturers’ Association. © , ¥ % * A SPECIAL de luxe trans-Continental _ train with every compartmeni, drawing-room and club car equipped | with radio loudspeakers -left New York" recently with a contingent of executives _ of the electrical industry on their way ° to a convention in San Francisco. ‘To ensure continuous entertainment during the trip a special receiving equipment and an extensive switchboard was installed and operated by an expert engineer. In addition to the radio apparatus an electric gramophone and.. complete supply of records was plaeod_ on the train. , a * RECENTLY an attempt was made to persuade the British Broadcasting Company to include talks on spiritualism in their programmes. Despite a definite refusal to accede to such a request, those interested are making «a further endeavour, this time in connection with spiritual healing througa organised prayer. It is alleged that a committee of distinguished physicians and surgeons ‘on’ the other side" has been active for some time past, and has decided on a plan of campaign for 1 general toning up of the health ol humanity through stimulating praycm by wireless! RE a z THE larzest: studio of the Budapest brou jyysting station is reputed to be one of tne most perfect in the world. | The walls are of marble, with draperies which may be adjusted to suit any item of a programme with precision. The conductor’s. box has a triple glass front, mat*tit absolutely soundproof. Thus he e#i conduct and watch his fuil ovehestra, but can bear their perform-. ance only as a listener does-by means y of « ‘loud-speaker or headphones. ‘The producer has a little office adjoining the conductor’s box, and controls a signalboard in the studio which makes verbal instructions for the most part unneces- ' sary,
