SHORT WAVE TRANSMISSION

HIGH SPEED INDIAN TESTS

SUCCEED. 130-150 WORDS A MINUTE. IBy Cable - Press Assn. — Copyright! (Received 26, 10.10 a.m.) London, Aug. 25. Despite temporary disorganisation of the aerial test due to a lizard crawling into a feeder tube in the receiving apparatus, Marconi’s short wave beam stations at Grimsby and Skegness for high-speed communication to India successfully passed the seven days’ Post Office test. The average speed was 130 to 150 words a minute, with 18 to 21 hours daily capacity and a circuit of 180,000 daily in each direction. The stations are only required under Government contract to de spatch and receive simultaneously 100 words a minute during a daily average of 12 hours. Mr. Kellaway said the Indian beam stations had been able to work continuously at high speed during ths monsoon period, a remarkable testimony to the system’s freedom from atmospherics. The Empire now possessed the most complete and most up-to-date service in the world. Although the Indian stations were erected, communication between Britain and the dominions thereby would not be completed before the end of 1928, when telephone subscribers in England should be able to speak to any part of the dominions. The beam stations enabling Canada and Australia to communicate direct were nearing completion and Marconi’s will open within three weeks commercial beam telegraphic services from England to South America, and England to the United States. The Gnmsby-Indian transmitting installation occupies the same room as the Australian, which works a single wave length alternatively directed easterly and westerly during different parts of the day, while th* Indian one allows the use of the second wave length, transmission being always in one direction. Hie Indian aerial system has five and the Australian three masts.—(A. and N.Z.)
