Radio Round the World

OT long ago the Marchese Marconi ‘ spoke to Argentine listeners, sending greetings to the three million Italians in the Argentine and the seventy thousand British there. He spoke from the Board Room in Marconi House over the London-Buenos Aires radio-telephone circuit, and his words were re-broadeast by Radio Excelsior, the new 20 k.w. station built by Marconl’s. In his address the Marchese stated that he helieved Radio Excelsior to be.the most powerful broadcasting station in South America, and its aerial 700 feet high, to be the highest aerial in the world devoted solely to broadcasting. b & O far Bulgaria has only possessed a small radio station of 500 watts, which has been onerated by an amateur organisation, This station is now to be replaced by the three kilowatt transmitter presented to the Queen by the City of Rome. Plans for a mucb more powerful station are under consideration by the government in order to combat the national propaganda of surrounding states. . ITH the advent of a new Director- ‘ General the German Reichsfunk intends to make drastic alterations in its organisation during the next few months. The main aim is to bring all studios under one central contro] and to place the stations completely in the hands of the ruling political party. Aceording to a Berlin report the first step to be taken is that of a thorough ehange of personnel in order to make room for over 1,000 active members of the National Socialist organisation, In adidtion, great efforts are to be made to hurry on the construction of the new Hamburg and Berlin transmitters; the former is due to be opened officially in the antumn. 2 S HE increase in the number of licensed listeners in Switzerland for the month of June last amounted te almost 3.000. * = * ‘AS only non-Jewish composers of strictly Aryan origin are permitted to figure in the German broadcast programmes, the authorities have decided that these regulations must also apply to all musicians, whether dead or alive. Acting on this principle the broadcasting studios have been forbidden to transmit even excerpts from the works of Offenbach. . Ss g ED HE Cracow station, in Poland, has eeased its educational transmissions because it has been found that "very few schools are equipped with receivers." e ® F ULYSSES A. SANABRIA, youthful Chicago television experimenter and inventor, has moved his laboratories from that city to New York City. He demonstrated his latest device in a New York department. store, where the attendance was about 20,000 a day. Images were sent over a wire from the store window on the ground floor to the receiving system on the tenth floor. A carbon dioxide are lamp was used in conjunction with a mechanical scanning system, .and the pictures were shown on a screen six feet high and four feet wide.. There was sound

accompaniment. The pictures were clear, in black and white. Mr. Sanabria believes that television will beeome a2 commercial practicability in about two years, and he further believes that the electrical scanning system will be used. This includes cathode ray tubes for pickup and for the receiving end. a % Ea ° HH new transmitter on the Monie Ceneri, overlooking Lugano, is perhaps the most inaccessible station in the world -to visitors. Not only is: the broadcasting plant situated on ° the summit of a high mountain, but, in addition, it is located in a fortified zone to which entrance without special authority is strictly forbidden. The studios are in the neighbourhood of Lugano, on the borders of the lake of that name. After having tried various wavelengths, such as 680 and 760 metres, which unfortunately caused interference, the station has now temporarily settled on 1.143 metres, % * co) ORB than half the visitors to the Olympia Radio Wxhibition of last year were women though in 1929 the fair sex made not more than 15 per cent. of the total of entrants.
