RADIO Round the World

pun opening call of Radio Vatican is "Taudator Jesu Christus." i * %* N England the number of subscribers to wireless exchanges is increasing steadily all over the country, and this is well on the way to becoming a big industry. The B.B.C. and the Post Office do not agree about wireless exchanges, the former wishing. to control them much more extensively than the latter will accept. There is a good deal of bother over the Sunday programmes. The exchanges naturally want authority to take Continental programmes when the B.B.C. is closed down, notably at lunch-time on Sunday. And the Post Office agrees." This, however, does not please the L.B.C., which nevertheless has acquiesced as long as foreign advertising is eliminated from the transmissions. And there is another complication, Adyertising is. a bugbear’ everywhere. th ue ¢

DEAN INGE is a broadcaster who is utterly regardless of the "mike." There is the famous notice "If you sneeze you will deafen millions" at the side of one of the microphones in the B.B.G. studios, but the Dean disregards it and puts the engineers to confusion. When he wants to cough, he coughs, and the microphone catches . the fuil blast of the nolse! we * TIF B.B.C. has stated officially that the power of the new "5 XX." the long-wave Daventry station, will be about four times that of the’ present outfit, and approximately 100 kw. will be delivered to the aerial. With this power it is anticipated that the new station will completely cover the whole of Great Britain for quite modest sets, during daylight hours. The motto adopted in the building of the plant is: "From Land’s End to John 0’ Groats in Daylight." : & = 2 HE British Radio Manufacturers’ Association look with some concern at the growth of wireless exchanges, which threaten to cut into the wireless trade. Indeed, the feeling in the trade is so strong that in one North Country town a local trader is said to have purposely interfered with the reception on the exchange receiver to. such effect that the exchange had to ask the B.B.C. to let them have a land- Hine link with a control room. * * "7 ALVES are used to heat and. supply hot water for the building housing the transmitting equipment of station WHK, at Cleveland... Phe rectifying and power-amplifier valves behind the transmitting panel are watercooled. From twelve to fifteen gallons of distilled water are kept moving past the plates, and this process ‘heats it io about 120 degrees. From the transmitting panel the water is led to the base-

rat ment of the building, where it passes around another coil, part of the heat heing transferred to a tank that supplies hot-water faucets. The water from the valves then travels through copper coils kept cool by fans. In warm weather, air from these fans is led outside the building, but in winter an auxiliary fan forces the warmed air through a register into the building. It.is only in rare instances that an emergency heater need be employed to keep the building warm. R Bg % So successful has the use of radio equipment been on patrol waggons belonging to the New York police that now there are no less than two hundred cars with receivers and transmitters operating on short wave lengths.

Hl new League of Nations equipment at Prangins includes two powerful shortwave transmitters-one French and one British, the latter haying a power of 20 kw. * * Ey MOS ’N’ ANDY, so well-known to lovers of the screen, are becoming popular as a result of their successes before the microphone. No less than 820 episodes have been broadcast by them, and this is sufficient proof of their appeal to the unseen audiences G Do a ROADCASTING seems in danger of "missing the boat" at the Madrid Conference in August. A communiqu? just issued by the German Ministry of Posts mentions that the coming conference will not concern itself with Ruropean wavelength problems. "The only broadeasting matter to be considered," says the report, "is whether the Wavebands at present reserved for broadcasting in all parts of the world should be widened or contracted, depending upon the needs of more vital radio services." mt % % HE consecration of the religious studio of the new London Broadeasting Palace having been found impossible, owing to the existence of a vaudeville studio underneath, the

officials have overcome the difficulty: by having it dedic: ated. r-) IIERE is a propability that Captain» * Pekersley,, M.LEB., F.TR., now, on a visit to Australia, will be invited by the Commonwealth Government to report on the Ausiralian National Network of broadcast stations, Captain Iickersley was connected with broadcasting during its infancy, when he acted as chief. engineer to the British

Broadcasting Corporation, as it was then called. He joined up with the corporation in 1923, and continued with it until 1929, helping to pilot it through many of its early vicissitudes. % Bg & MALL wooden masts, from 60 to 80 feet high, will be used for the aerial circuit of the Empire wireless station at Daventry. In all there will be seventeen aerials. Eleven of them will be of the reflector type and focused for transmitting beam-like waves in specific directions. Six different wavelengths will eventually be used: 14, 17, 20, 25.6, 32 and 48 metres. % ae Bo (CLAPHAM and Dwyer like an audience in the studio; theirs is the kind of humour that goes down better with a laugh at the back of it. Studio audiences are not always chosen from the artistes’ friends, and, contrary to the critics, the laughter is genuine and spontaneous! . ; * ™ ae THE first television demonstration in a moving railway train was given recently in England to determine|its possibilties in providing entertainm-ge for passengers. It was found that, though there were slight interruptj due to bridges and momentary lk conditions, the reception was. fairly good even when the train reached 60 miles an hour.

hd " HE B.B.C. will receive £1,366,000 in the coming financial year. The amount due under the agreements is £1.516.000, but this is reduced by £150,000-the amount which the B.B.C. agreed to give up as 2 contribution to the Exchequer in the national emergency. as ale th

aad ~~ vFEAT losses in welding are reduced by a new process in which highfrequency electric current is used. his current is like that used in radio. The process depends upon the fact that high-frequency currents are most intense on the surface of a conductor. The plates to be welded are brought together and connected by a wire. A high-frequency current is passed to the plates, accumulating at the outer edges to be welded, which are subject to melting heat. Other parts of the conductor remain cool. Seamless pines will be manufactured by this process. IIF progress of television experiments at the De Forest laboratories in America was temporarily halted recently by a fire which completely destroyed the broadcasting -studio and caused damage to other parts of the plant. A special camera which represented many months’ work and which was said to be the mos} advanced form of television pick-up so, far fleveloped, was completely destroged. Investigation revealed that the re started near a neon gas purifier when the glass bulb covering an are lamp suddenly burst and allowed the heat of -the are to ignite the gases.
