Radio Round the World

BECAUSE so many professional musicians are out of work, the Danish broadcasting authorities are reported to have banned the, use of gramophone reeoards for hrondenastinge.

"RUNNING water, two armchairs, two small beds, and a radio transmitter and receiver" are reported to form the main equipment of a new telephotographie car which has been put in service by the French Government for providing the Press with a quick photo service dealing with current events, * * Ea A "CRYPTOGRAPHIC" picture transmitter has been evolved by the French inventor, M. Edouard Belin, who claims that he is now able to send messages, drawings, and photographs in a manner which makes them unintelligible except to a listener aware of the "key." The cylinders of the transmitter and receiver are rotated at varying speeds. bid * & N Britain there is no midile course between the high road of legalised listening and the low road of piracy, but in Italy it is now possible to test a new set without a license for a period of ten days. And to prevent abuse of the arrangement the Italian Government decrees that all retailers issuing receivers under this rule must keep a careful check on the dates of issue and return, as customers may suffer from short memories! % % By ENMARK still heads the list among Huropean countries in the number of broadcast listeners per thousand population, the number being 119.5. Sweden comes next, according to the International Broadcasting Union, with 78.99. Britain still holds third place with 77.5 per thousand population, and is followed by Austria with 63.84. and Germany with 56.23. Hungary and Norway come close, and then comes Finland, which has stepped down a place in favour of Norway. = 2 e ""WWHE newspapers of the United States, either individually or cooperatively, must ultimately eontrol broadcasting in all its phases," writes Mr. F. T. Stockbridge, editor of the "American Press." Conflict between newspapers and the wireless have arisen on six points: News broadcasting, which trespasses on the newspaper’s chief function; demands on the papers for free publication of radio programmes as news; diversion of advertising revenue from newspapers to radio; the privilege, forbidden the newspapers, of broadcasting lottery advertising ; the use of radio for questionable advertising which respectable papers refuse; and the imminent possibility of television advertising displays, reducing newspaper display advertising. "It would require a very small

investment on the part of a few '‘newspaper groups," adds Mr. Stockbridge, "to acquire enough key stations to give the Press almost complete control of the situation."

DEVICE by means of which everything said by both parties concerned in a telephone conversation is recorded on a magnetic steel wire in such a manner that it can be reproduced at any subsequent time is the latest advance in communications technique announced by the International Telephone and Telegraph Corporation. The récord so obtained can be preserved as jiong as may be required, but it is also possible to obliterate the message so that the wire can be used over and over again. One of the important applications of the conversation recorder is in connection with long-distance cable and radio telephone calls.
