TELEVISION PROGRESS

NEW YORK - SYDNEY TESTS. A series of remarkable experiments in long-distance radio transmission of speech and television have been in progress during the past few weeks by Amalgamated Wireless at Sydney, in conjunction with the General Electric Company of America. At one stage of the experiments the American engineers, working from Schenectady. New York, placed a diagram before a televisor at the transmitting station. The diagram was “televised” and the output of the televisor w'as fed into the short-wave transmitter 2XA7, which sent it forth to the world in the same way as an ordinary radio signal. Amalgamated Wireless’ engineers picked up the signals at La Perouse on the special Aus-tralian-designed and manufactured transmitter 2ME, which rebroadcast the signals. The New York station picked them up again, passed them through the television receiver, and the diagram that was televised was reflected on to a screen after it had travelled to Sydney and back in a fraction of a second.

A further experiment carried out involved the use of a “talkie” apparatus. While an A.W.A. engineer in Sydney and a G.E. engineer in New York were chatting over the wireless telephone a “talkie” film was mads of their combined voices. The film was run through a projector to reproduce the conversation. The output of the projector was fed into the New York transmitter, broadcast, and picked up in Sydney by Amalgamated Wireless. The engineer who had taken pa»t in the conversation thus heard his own voice, together with that of his American co-operator.

Tests of many kinds are continually being made by Amalgamated Wireless in conjunction w’ith radio organisations in other parts of the world. It is all part of the research that is being carried on by AW.A. into various phases of radio phenomena.
