woe AN elaborately fitted research laboratory is maintained by the B.B.C. at London. HE receiving aerials for the transAtlantie wireless telephone service are situated in Fifeshire and are about GOOft. long. ON EB U.S.A. firm boasts that by means of radio advertisements it sold between February and April sixty thousand pairs of silk stockings. ‘THE Duke of York was present at a Scout camp at New Romney, August 9, when part of a sing-song by the boys was relayed from London. [ Great Britain there are twentytwo stations, but the revenue is more than £1,000,000 per annum from two and a half million listeners. MOVING Coil Loudspeakers are known in the country of their origin (U.8.A.) as Dynamic Speakers, a name applied by the patentees. HE Norwegian railway authorities are installing a regular train telephone service, using a wavelength of S4 metres, on certain railway lines. [ Czecho-Slovakia the sole operating right is held by a commerciallyconstituted company, in which, however, the Government holds a major interest.

f UNIQUE radio store in Oregon (U.8.A.) is built as an exact duplieation of a radio receiving set. It is equipped with dummy switches, knobs, and dials. [t appears that even the B.B.C. cannot satisfy all. A "Bored by the B.B.C." campaign has been inaugurated, and deputations wait on Parliament complaining about Government control. [TURING 1927 transmission from all the B.B.C. stations covered over 68,000 hours. Entertainment naturally formed the bulk of all programmes, but there was a strong and growing demand for other features, REAT financial difficulties have beset the career of the "Radio Belgique" Company of Belgium, since its inauguration a number of years ago. A licence is payable but no part of this is available to the company. ANY more stations will be necessary before the companies can provide services that will enable Australian listeners in all or in most settled parts to obtain service reasonably free from distortion or interference.

‘THE Lille station, France, recently broadcast a "balloon" transmis: sion, the impressions of a voyage in the air being relayed to the station and rebroadcast. SEVERAL of the few amateur stations in the Kenya Colony (Africa) have been heard in England, despite their low power. Wireless transmitters are now found on almost every conceivable portion of the globe. PERMISSION has been given for the broadcasting this year of the Cenotaph service from Whitehall on Armistice Day. A permanent underground cable has been installed between the Cenotaph and a secluded control point a little distance away. HE Munich station (Germany) recently scrapped its metal masts and replaced them with wooden masts, 190 feet high. This has improved the range of the station by removing a certain amount of absorption which had previously hampered reception. [LITTLE has been heard here of the Dynamic Speaker, but it has been manufactured and sold in huge quantities in the States for the past two years. The patentees are producing

1000 units per day. Others have now eee licensed to manufacture the prouct. T is pleasing to see that, in recent international amateur tests’ New Zealander (3AR). secuared fitt?, place against a very large field. He was surpassed only by an Englishman, a Belgian, a Porta Rician, and an Australian. The winner, 5BY, is often heard in Australia. RAZIL is not the best type of country from the physical aspect for broadcasting, possessing as it does, its principal cities along its extensive coastline, with a hinterland largely uninhabited, but its broadcasting stations are nevertheless relatively numerous, though generally of low power. F the Huropean broadcasting systems, that of Spain approaches most nearly to the standard of American competition and freedom from regulations. Commercial consolidation is, however, at work, and a Government inquiry into the whole subject was begun in 1927. Nor long ago, the New York Police Department brought 110 wireless direction-finding sets at a cost of about £3000. It is now announced that these are to be sold by auction, experiments having proved that the sets are too tricky for the average policeman to handle.

It has been recently intimated. that the Government were to take over the service, (THE second annual American Radio Trade Show, held last month in Chicago, was quite a brisk affair. It occupied 30,000 square feet and 25 floors of rooms, 155ft. of these being used: for demonstrations. Exhibitors numpered 205, of which 48 were setmakers, 43 of whom showed "Mains" sets. Moving coil loud-speakers were predominant. JN Switzerland a number of Stationey belonging to local companies, opel ated until recently without interdependence. A union has now _ been formed which includes all station except for the time being, one. License revenue is available for their support. but the nature of the country and the distribution of its people. make the situation of broadcasting exceptional.
