R E HAYCOCK WIRELESS WONDERS LISTENING AT LA PEROUSE, , SYDNEY WORLD’S RADIO CENTRE Overlooking Botany Bay. on the j heights of La Perouse a: Sydney, j stands the most important and largest wireless receiving station in the southern hemisphere. Of the most modern design, the equipment incorporates the latest ideas in commercial receiving i apparatus. From a network of stations through- j out the' world, traffic is received there. ; Messages from ships’ stations in the Pacific and Indian Oceans, and from the coastal radio stations on the southwestern seaboard of Australia. A wireless telephony service is also maintained between La Perouse and the trawlers operating off the Australian coast. La Perouse is also the terminal of j the wireless telephony service between i Great Britain and 22 European counj tries and Australia, and will be the i i Sydney switching terminal for the ■ ; wireless telephone service from Great ! j Britain ana Europe to New Zealand. The latest news of the world is also j received there from the Rugby high- ; i power station, while reception is 1 effected of broadcast programmes i Transmitted from English, American and Continental high-power broadcasting stations. SHORT-WAVE RANGE The enormous ranges at present • attained by short-wave working is demonstrated by the reception at La Perouse of experimental communications from short-wave stations in Britain and Europe, the United States, Canada, Africa, Asia and the Dutch East Indies. La Perouse maintains communica- i -tion with all the short-wave stations j in the Pacific, including Rabaul, Suva, \ Noumea, and San Francisco. Effective j communication is also kept up with ships’ stations, equipped with shortwave apparatus, crossing the Pacific ! and Indian Oceans. The system of centralising wireless j activities, developed by Mr. E. T. Fisk. Managing Director of Amalgamated j Wireless, has resulted in the establishment of three large centres —the transmitting centre at Pennant Hills, • Sydney, the receiving centre a-t La Perouse, and the control centre at AW A Headquarters in the City of j Sydney. Under the old system it would have been necessary to have a separate site for each of the nine commercial services at present operated by Amalgamated Wireless from Sydney. Operators are located at only La Perouse and headquarters, the staff at Pennant. Hills transmitting station comprising radio engineers alone. The operating efficiency of all the | services has been greatly improved by the system of centralisation, apart from the economy both in equipment and personnel. The visitor at La Perouse receiving . station sees only a small building and a few masts, but the operator inside the building sees one of the wonders i of modern science—a receiving station I with gigantic electrical “ears.” able ! to detect the smallest vibration, aqd to read, instantly, its messages, i whether it has travelled one or 10,000 : miles. With headphones clamped to his ears, each operator sits before a type- j writer, with a Morse keyboard at the ; side. This is a simple, unpretentiouslooking instrument, but a depression j of the key actuates a transmitter at Pennant Hills, some 16 miles away. While listening to a message from a ;

ship, the operator can. simultaneousl*seud a message to it, or to another vessel by the Pennant Hills marine transmitter. Another operator is in touch with far away Noumea. Others are ev changing traffic with ships, with New Guinea, or w ith coastal radio stations Others again are listening in to th» latest Press news from England ami the Continent, or are receiving messages from experimental short-wave stations in Europe, America and the East. Day and night messages are flashed from all parts of the globe to be picked up by the ever-watchine operators in Sydney. The touch of a keyboard, the depression of a switch immediately puts the transmission of messages into action. Altogether nine services are operated from the La Perouse station. Messages from Rabaul, the Fiji s t a . tions, and the beam station at Bravbrook. Victoria. received at L, Perouse, are automatically relaved i 0 A.W.A. headquarters, Sydney. PRINCIPLES AND EXPERIMENTS The electro-magnetic principles discovered by Oersted and Faraday a century ago. the experiments 0 f Joseph Henry, and the discoveries of (hat great "electric king," Lord Kelvin. the mathematical predictions of that brilliant physicist, James Clark Maxwell, and tile laboratory work of Henrich Hertz in ISS6, verifying Maxwell's deductions, were milestones in the evolution of wireless telegraph;' even though many of these scientists were not at the time aware of the uses to which their discoveries were to be applied. Branley, Lodge and Popoff, noted scientists, were* also instrumental in. advancing experimental wireless. It remained for Marconi, however, t hen a youth of 21, in 1595, to devise a practical scheme of communication without the use of wires. A stroke of genius resulted in a new science which was destined to have a greater effect on human activities than any invention—except probably printing—of the preceding 19 centuries. Australia today is in the forefront of wireless progress, and much of this is due to the experiments carried out by Mr. Fisk, the managing director of Amalgamated Wireless, during the past IS years. IYA MUSICAL COMMITTEE A meeting of the IYA .Musical and Dramatic Committee was held at the Auckland studio of the Radio Broadcasting Company last Friday evening, the Rev. A. B. Chappell presiding. A motion of sympathy with the relatives of the late Mr. Christopher Smith was passed, all members standing. The chairman expressed the feelings of the committee and said that the loss to the community at large was very great and that listeners had lost a great musician and a great friend. The question of the company's subsidy to the various musical societies was again brought forward and it was reported that the Aeolian Orchestra was willing to fall into line on the terms of the committee's recommendation. Other societies had yet to bring forward their decisions. The closing date of the first section of the song-writing competition, namely, for the poem suitable to be set to music, was fixed for September 26 next, and the judges were appointed, subject to their consent.
