BEAM WIRELESS PROGRESS.

Thrilling Exposition of Progress.

MARCONI’S CONFIDENCE

By Cable —Press Association —Copyright. Australian and N.Z. Cable Association. (Received April 10, 5.5 p.m.) LONDON, April 9. An interesting exposition of the progress made in beam wireless, was given in the board room at tno Marconi House, in which was hung a page of “The 'rimes” in sections recently transmitted in facsimile, throequartors of a mile by wireless.

Mr Marconi strolled in smoking a cigarette, and invited his guests to im it ato him. Ho explained that the Australian beam system could deal with 150,000 words daily, which was treble the present cablo traffic. Ho would shortly test the shorter wave, lengths to Canada, and Australia, in order to increase the working hours, carrying capacity, and overcome fading. Tho present experiments pointed to the probahlo abolitino, or at any rate, the certain diminution of this, and it was hoped to secure a twentyfour hour Anglo-Australian service by adding one or two wav© lengths.

Mr Marconi said that already they were working double tho number of hours specified in the contract. The present capacity was sufficient for existing business. It was possible to superimpose a telephone channel ©n tho telegraph services, enabling two telegraphic and one telephonic services to work simultanously, thus obviating separate stations and apparatus. For this new development, the apparatus is under construction. The privacy of the Australian telephonic communication, would exceed that of the American, owing to tho extra costliness of the eavesdropping apparatus. Television and facsimile transmission were possible later, thus facilitating long messages, owing to it being unnecessary to spell out each word. This would economise in operational expenses. It is hoped shortly to establish the beam connection with the United States, Argentina, China, Japan, and other countries. Tlie beam system, said Mr Marconi, would not render Rugby obsolescent, as that station fulfilled a definite and different purpose, and broadcasting did not clash with directional wireless. Mr Iveliawny recalled that tho success of tho beam system was preeminently due to Mr Hughes, and to Mr Fisk’s determination not to submit to the weigiit of technical evideneo in 1921 in favour of the relay system. Australia’s smallest townships would soon be linked up with the main beam, obviating all outback isolation. This would also bo applicable to India and other countries. Mr Marconi added that soon tho beam would enable concerts ami speeches to be transmitted between Australia and England, either way, and afterwards broadcasted, listenersin being able to pick up, with crystal sets, anywhere in the world. Picture transmission (when reliably travelling waves were assured), would be as easy between England and Australia, as between places half a mile apart.

FIRST DAY IN AUSTRALIA

BIG SERVICE OPERATING

MELBOURNE, April 9

For tho first day of the Beam wireless, about 3500 words were sent from Australia and twelve hundred from Britain. It is stated that the service is working in a highly satisfactory manner allhough the traffic is heavier than anticipated.
