VALUE OF .BEAM SYSTEM. TESTS PROVE EFFICIENCY. REDUCING CAPITAL COST. By Telegraph—Press Assn.—Copyright. Received July 3, 5-5 p.m. London, July 2. Signor Marconi, in an address to the Royal Society of Arts on the results of experiments of the ijeam system, declared that tlnsre was comparative economy in the capital cost of the stations equipped with this system. A small amount of electrical power was needed, and the capability of working at a very high speed should make it possible to bring about a substantial reduction in telegraphic rates. Referring to the telephone tests between Britain and Australia, Signor Marconi stated that a wave length of )2 metres was employed, the total power being supplied by valves of 28 kilowatt*. Reflectors were not used at either end. The results were easily a record for the ratio of the distance to the wave length. Sydney being approximately 189,000 wave lengths from Cornwall. He -believed it had been proved conclusively and adequately that rhe designed reflectors would enormously increase the effective strength of the signals, besides increasing the hours in which it was possible to communicate with the most distant countries, thus reducing interference. Referring to the Argentine tests Signor Marconi said he had been advised that the signals were received at Buenos Aires with such regularity and extraordinary strength as to permit a service conducted at arty ipeed. The Argentine authorities wei-L of the opinion that their station should be immediately equipped with the system, which they were confident was capable of handling more than double the traffic in six hours than in twenty-four Iv-nrs with the present super-pewor station. Signor Marconi said he was convinced that by means of these comparatively small ’stations far greater wordage could be transmitted daily between England and the distant Dominions than was possible previously. It was planned to build powerful and expensive stations.
