NOTES AND COMMENTS

A new company -is being formed in England, under.., the name "Whdess Pictures, Limited." The firm will bave a capital of £425,000, and busi ness will consist of constructing and selling radio picture receivers. In Great Britain and the States architects are now giving full consideration ■to radio requirements in house building. Fixtures for aerials arc incorporated in plans, which also show locations for receivers and a wiring system which enables loudspeakers to be shifted from room to room and plugged into wall sockets wired to the.set. The Marconi Company has just received the British Broadcasting Corporation "s order for the supply of two high-power broadcasting ■transmitters with an unmodulated aerial energy of 50 kilowatts. These stations will be erected at' Potters Bar, near London, ii. 'pursuance of the British Broadcasting Corporation '<? scheme, for covering the whole of Great Britain with n smaller number ,of broadcasting stations of a higher power than those at present in use. A new broadcasting station is on the air from Sydney. It is the old 2TJW, which was sold some weeks ago to Radio Broadcasting, Ltd. New transmitting apparatus has been installed, and after a few nights and days of testing, 2UW is now definitely on.the air again using the wavelength of 267 metres. Mr. J. M. Prentice is in charge of the announcing) and programmes; to listeners in New Zealand he will need no introduction. He is telling the bod-time stories "qti original lines."

Transmission over long land-lines has been' very thoroughly tried out in the eastern States of Australia within the past few months, mainly in order to find out what may be expected if iclay stations are erected in the inland districts. Over'4ooo miles of trunk lines were used, with varying, butj on the whole, satisfactory, re-. stilts. . Transmissions were made to Sydney from covered transmissions from Orange,. Goulburn, Lismore, Windsor, Newcastle and Grafton in New South Wales, and Richmond, Melbourne* and Dandenong in Victoria, while relays were also arranged in Brisbane, Melbourse and Adelaide;. In some cases speech and solo music came through well, but concerted, instrumental and choral music was choked in transit, in other eases distortion and interference was met with. However, the tests showed that' if. amplification, is correctly carried out at points on route and extraneous noises are'-elim-ii.ated, working over long trunks presents' no diffieultv.
