BEAM WIRELESS.

FLANS FOR STATION. LONDON, July 10. The "Daily Telegraph" understands that the sub-committee of the Cabinet dealing with wireless is discussing with the Marconi Company the question of erecting a beam station in England to communicate with a similar station in Australia. It is believed that the plan under', negotiation proposes that the Marconi Company should erect the station, which the Government will take over subsequently if its operation proves successful. — (A. and N.Z. Cable.) Lecturing before tlie Society of Arts on recent experiments in short wave directional wireless, Signor Marconi predicted the substitution of the short wave beam for the present long wave systems. In the inter-Empire scheme the beam's possibilities were infinite, as the range was unlimited and it was economical because les3 power and equipment are needed. "In a beam test on May 30 I spoke easily to Mr. E. T. Fisk, managing director of the Amalgamated Wireless (Australasia) Ltd., at his house in Sydney from Poldhu, Cornwall," he said. In conversations from Poldhu to my yacht off West Africa, the beam provced superior to the Carnarvon broadcast messages. When speaking to Sydney with the beam in the mornings we send westdard, fleeing from the sun, across the Atlantic, across America, and across the Pacific, a distance of 12,219 nautical miles. In the evenings the reverse process obtains, going 9351 miles across Asia to Australia. "The Australian conversation constitutes a record for the ratio of distance to wave length, namely, 159,000 wave lengths." M Godfrey chairman of the Marconi Co., supports Signor Marconi regarding beam wireless. "The beam," he says, "opens ranges previously commercially impossible, ow- j ing t the huge outlay. The beam is ideal for wireless telephony. "My company is not building further high power stations. In future the power will not exceed 25 kilowatts. An era of immense magnitude is opening." Questions are being asked what will happen to the 600,00) super-power station building at Rugby, which is already out of date.
