Radio Round the World

1. + atries; Denmark has the largest ratio of } wireless licenses to total population. 4During 1930 the number of licexses rose A-from 308,927 -to’ 420,000. This pheno:: Pun latest.scheme in "wired wire-, less" distribution of programmes throughout hotels, hospitals and similar _ establishments, comes from America, j -and consists in using a low-powered ‘transmitter in combination with a stan‘dard receiving set. The incoming’ sigpals are first amplified by the central yeceiver, and are then re-transmitted on ‘a: shorter wavelength:so:'as to feed a ‘ pumber of shortwave receivers located’ ‘in each of the rooms. * \ g +B. CHART recently issued by the International Broadcasting Union rez: meals" the fact that of all European coun- " . ;gnenal increase is thought to be due t6. the enterprise of the broadcasting authorities in determining and taking F » into account the tastes of listeners in ‘+ the matter of the composition of Dro: grammes, % & r DURING a recent murder trial in Los. Angeles, the judge was annoyed to \ discover, through a chance remark by a friend, that someone was evidently bringing 2 microphone into the court-|-room and broadeasting the proceedings. An investigation led to the disclosure that a local radio station was broadcasting the trial by dramatising the transcript and making it appear as if a microphone were in the court-room. © &; | conference of judges was held to discugs the matter, and action will probably , hie taken against those responsible. m {OUR years ago by, ren son of its then high power of : k.w., ranked foremost among the European transmitters. Now its yoiee can only be faintly heard amid the,ronr of its more powerful neighbours, which have sprung up allround. It has there: fore been decided to build a new: ‘and greater Radio-Vienna which will hayea power of 100. k.w., so that once mor€*its voice will be heard above the radio chatter of Europe. The new statiow will be erected about twenty-five. mniles from Vienna, so that it will not ‘dnterfere with foreign station receptign in the Austrian capital. ; % tt * PARis will shortly possess ofe of the most powerful stations in Europe. A new transmitter with a power rating of 120 kilowatts has been erected on the outskirts of the city. +: Apart from this huge increase in power, the new station has an aerial system which employs three masts over 600ft., high. The transmitting plant is ready for operation, and will be brought into service as soon as the sanction of the Post Office authorities is obtained for the establishment of lines to link ‘up the transmitting plant with the studios in Paris. The wave-length employed is 1725 metres,

"J+ $ssannounced from Paris that two . interesting radio discoveries are en- _ gaging, ¢he attention of experts. The first,is 2 triode valve capable of dealing with a power of 150 k.w. The filament consists of eight parallel strands of wire, "If necessary, the valve can be dismantled. The second discovery is in »" conne¢tidn with the radio transmission of. pliotogfaphs, and is credited:to M. Beliny the: famous inventor, M..Belin’s syste’ ‘insures that all photographs transiiiitted | over his apparatus are "gerambled" so that’ only those’ ‘Dossessing recéiving gear previously synchron--ised: with-the-transmitter are"dble-to receive’ Dletuires. % * pat tatest developments in receiving ‘sets were displayed on over 400 ‘stands. at the National- Radio! Exhibi"tot. ield recently in London. -Over 5000 different types’ of receivers, ranging from a diminutive portable to a massive radio gramophone ten feet high, were on view. The gallery of the main hall was this year. entirely ° deYoted..to sound-proof rooms in which prospective purchasers could, test the range.and quality of the various sets on exhibition. On an upper storey a ‘dance floor flooded with colour by means of a new lighting system was prepared for the of visitors. % me . % M R. O. H. CALDWELL, a former member of the'U.S. Federal Radio ‘Gomnrission, appears to devote his time td: discovering ‘novel uses for radio. ] Here is"his‘latest: "At least 50 per ent. more eggs+will be produced for ~market » if the ‘poultry farmer. offers fe fo; his hens the, same opportunity to heir, good: radio programmes that he "extends to his family. The secret in gétting the most out of the hens by the radio. system is to turn on the. proal-""¢ 4 ‘"-easts early in the day and keep them ‘-goifig until chicken bedtime. This : dnethod increases the average hen-hour production and brings a new spirit of "sénvi¢e. to the chicken coop.

The KDKA broadcasts have brought cheer to the "nvembers of many famous expeditions, including that of Admiral Richard. B. "Byrd, with base established. at Little Xmerica, Antarctica, and that of Cap¢fiin Bob Bartlett and his expedition on the Greenland seas. : News items, mes‘gages and musical entertainment are in"cluded in this special service,
