This photograph, taken by The Advocate in 1988, features the 3AR and 3LO radio transmitting station on Sydenham Road, Sydenham. The station's transmitter is a 705-foot (215-metre) steel lattice mast, recognised as one of the tallest radio masts in Australia. The structure was erected in 1938 when radio station 3LO relocated its transmission facilities from the Maidstone-Braybrook area to Sydenham. Although photographed in 1988, the image was later published in a 1989 Advocate article that discussed speculation surrounding the future of the site. By that time, a decision had been made to retain the landmark structure, which remains a prominent feature of the local landscape and an important reminder of the region's broadcasting history.The 3LO transmitter at Sydenham is one of the most important pieces of broadcasting infrastructure in Victoria. It is also one of the most recognised landmarks in Sydenham. The site is officially the ABC Radio Mast and Transmitter Station, Sydenham Road, Sydenham, built in 1938, and it still broadcasts 774 kHz ABC Melbourne (3LO) today6862 - 3AR And 3LO Radio Transmitting Station Sydenham Road Sydenham 1988 Photograph (Advocate 700).JPG3lo radio transmitter, 3ar radio transmitter, sydenham road, sydenham

This telegram was sent from the Royal Netherlands Airways, Sydney, to the manager of ABC Radio Station 2CO, Corowa, New South Wales. This telegram relates to the 1934 London to Melbourne Air Race. The telegram records the Royal Netherlands Airways' thanks to ABC Radio 2CO radio staff for their efforts in broadcasting an emergency message to the residents of Albury after the Dutch airliner ‘Uiver’ became lost at night in bad weather. As requested local radio listeners drove their cars to the Albury racecourse and illuminated an emergency landing ground using their vehicle headlights. This allowed the lost airliner to land safely.This item relates to the London to Melbourne Air Race of 1934, a significant event that shaped Australia's history as it proved travelling to and from Australia could be done within a reasonable time by air, thereby making the country less isolated. Up to that time Australia was three weeks away from Europe by steam ship. The Air Race was dreamt up by the Lord Mayor of Melbourne, Harold Smith, to commemorate the centenary of Victoria's statehood and was sponsored by the Melbourne chocolate manufacturer Sir MacPherson Robertson. The Royal Netherlands Airways entered a Douglas DC2 plane 'Uiver' - the largest aircraft in the race, and the only one to carry passengers as well as crew, to show that a commercial passenger service to Australia was possible. But in the last leg of the race, the Uiver lost its way in an electrical storm over the Riverina town of Albury. Several communication methods were used to land the plane safely, including the signalling of the word "Albury" in Morse code using the town's street lights. Local ABC Radio station 2CO also made a call for locals to light up a makeshift landing strip for the plane at the town's racecourse. The plane landed safely and the next morning with the help of the townspeople who pulled it out of the mud, took off and finished the race in second place. The story of the Uiver points to the importance of communication in its various forms: two-way and broadcast radio, Morse, and light signals. The survival of the Uiver is a reflection of the ingenuity of Australian communications and the solutions that can be found through the sharing of ideas of information. The landing of the Uiver was an important moment in Albury's social history, as residents participated in the rescue of the plane and its passengers, helping the Uiver to continue on its journey and finish second in the Race. When the Uiver crashed in the Syrian Desert in December 1934, Albury residents contributed to a memorial which honoured those who were killed.

This tape is from the first telegram ever sent in Western Australia. This important event occurred on 21 June 1869. At this time the transmitted message was received on paper tape and later transcribed onto a telegram form for delivery. The original tape was presented to the Honourable Frederick Palgrave Barlee, Colonial Secretary of Western Australia, as a souvenir. "FPB" appears on an engraved shield on the lid. James Coats Fleming, the first telegraphist and later Superintendent of Telegraphs, sent the telegram. During 1875, Colonial Secretary Barlee transferred from Perth to Belize and then to Trinidad where he died in 1884. The fate of the case and spool, souvenir of that first telegram, was unknown. In July 1940, the WA Agent-General in London advised the Premier's Department in Western Australia that a Mrs EW Hillyer of Hertfordshire had the spool and case and was willing to sell it for ten guineas ($21). The Postmaster General's Department agree to the purchase and it duly arrived by registered mail. As a communications museum was planned in Melbourne, it was sent there to be included in the collection. Nothing more was heard until early 1980s when the relic arrived at the Post and Telecommunication museum in Perth. The case had been found in an old Melbourne strongroom where it had apparently been placed for safe-keeping and then forgotten. Initial attempts to decode the message on the tape were unsuccessful. Eventually, it was discovered that the Western Australian Telegraph Company, responsible for that first transmission, had devised its own code. A copy was obtained from the Battye Library and the message deciphered.This Morse tape is of historic significance as the first telegram ever sent in Western Australia. The occasion was momentous as the transition point between isolation and ease of connection for business and personal communications. The case is of aesthetic interest for the craftsmanship involved in the engraved text. Further, the tape has research potential owing to the unique information contained within this tape; that is, the code of the Western Australian Telegraph Company. This tape, may in turn be used to decode further messages sent by the Western Australian Telegraph Company. As the first telegraph message sent in Western Australia, this tape is rare. Despite a tumultuous journey from 1869 to the early 1980s, the tape's ceremonial wooden case provides provenance information which supports the tape's historic importance.Small wooden case (.1) holding a length of morse tape (.2) which was the first telegram ever sent in Western Australia .

This was the first press photograph transmitted by radio from England to Australia. On 16 October 1934, South Australian aviator, C J Melrose, was pictured beside his plane at the Mildenhall aerodrome, England, preparing for the start of the Centenary Air Race. Within hours of capture, the image was transmitted from London to Melbourne and then sent via picturegram to Sydney’s press, the greatest distance a photograph had been transmitted over radio. Wirephotos, as they are commonly called, are produced through electrical pulses which travel along telephone or telegraph wires, or radio waves. Like the transmission of Morse dots and dashes, the technology communicates the light and dark portions of an image, to be recorded on a negative or photographic paper at the receiver’s end. Previously, photographs of an event appeared several days after the fact; wirephoto technology enabled visual communication with relative speed. Our consumption and expectation of the immediacy of news and communication continued to grow, an expectation that forms the basis of time-based social media activities such as Snapchat or Facebook and Instagram stories.london to melbourne air race, wirephoto, picturegram, uiver, james melrose

This is a Morse Code key. Morse Code is a method of transmitting text information using short and long signals (‘dots and dashes’). It is named after Samuel Morse, the inventor of the telegraph and was developed in the 1860s. It was used extensively in the 1890s for early radio communication before it was possible to transmit voice and continued to be used in the 20th century along with voice transmission , especially by amateur radio persons. It was also used in military and naval communication but not so much today. It is believed that this Morse Code key belonged to Ted Salamy, a jeweller and the first person in Warrnambool to hold an amateur radio licence (1924 Call Sign A3AJ, the 35th licence issued in Victoria).This Morse Code key is of interest as an object more used in the past, especially by amateur radio persons. It is believed to have been the property of Ted Salamy, the first person in Warrnambool to hold an amateur radio licence. This is a metal Morse Code key with an oval metal base. It has three screws inserted in the base and two more screws attached to the sides of the base. There is a key lever on top of the base and this is adjustable. The hinge on which the key lever sits is missing. The lever has a round black knob at one end. ‘Made in U.S.A. H15.682’ Wm.M. Nye Co Inc.

The telegraphs were originally a separate department in NSW and became part of the post office in 1893. After federation the use of telegrams increased until it peaked in the 1940s. The last telegram was transmitted in Australia in 1983. Social telegrams were encouraged and special pictorial forms and envelopes were designed. A special form and envelope in purple was used when conveying condolence details during World War 2.Brown paper envelope with window to show address TELEGRAMpost office, bentleigh, telegram

They sphygmograph was devised as an improved device to measure blood pressure, and was a marked improvement on the first machine of its type. The sphygmomanometer was considered cumbersome and the Dudgeon sphygmograph was smaller, and once placed into its box, could be carried in a pocket. The Dudgeon sphygmograph was introduced in 1881. It was strapped tot he wrist with a metal strip that moved a stylus. This transmitted a record of the pulse onto smoked paper, creating a record of blood pressure.The sphygmograph is housed in a purple-lined, leather bound case with a metal hinge and clasp located halfway up the case. It is constructed from chrome and comprises several moving parts including wires, knobs and handles. A black fabric strap with a metal attachment is also present, used to attach to the patient's wrist.blood pressure, dudgeon, pocket-sized, portable

A telegraph or Morse key, sends a series of electrical signals down a telegraph line or via radio frequencies; the signals are interpreted as Morse code, a binary form of language constructed of 'dots and dashes', combinations of which correspond to letters of the alphabet. The motion of the key acts to complete an electrical circuit between the sender and receiver, producing a short pulse 'dot' or longer 'dash,' the space between the code indicates a broken current or wave.Device used to transmit telegraphic messages in Morse code through the manipulation of electric signals. The metal 'key' sits in a central bracket on which it moves up and down aided by a spring, controlled by an operator pushing the black Bakelite knob on the protruding end of the device. The motion presses the key onto a circular metal disc, completing the circuit and sending an electrical pulse to the receiver. The apparatus is secured to a wooden base with wires attached to the terminals; a cut out section of the base suggests wires may have entered through this area, attaching to a battery.Printed ink on base: "PMG"telegraph, telegraphist, morse code, mechanisation

This photograph, taken by The Advocate in 1999, features one of the buildings of the former 3LO Radio Transmitting Station located on Ashley Street, Maidstone. Radio station 3LO commenced broadcasting on 13 October 1924, with its first transmission featuring an outside broadcast of the opera La Bohème from Melbourne's His Majesty's Theatre, including a performance by Dame Nellie Melba. The station was named after London's famous radio station, 2LO. The transmission facilities were established at the Ashley Street site in the early 1920s. The station originally operated from a powerful transmitting tower and associated equipment buildings located near the Maribyrnong River. The site was chosen because radio transmission technology of the period required transmitters to be located close to their audience. In 1932, when the Australian Broadcasting Commission was established, control of 3LO passed to the national broadcaster, making the station one of the foundations of the ABC radio network. In 1938, 3LO's transmission operations were moved from Maidstone to a new site at Sydenham (then often described as St Albans or Delahey), where broadcasting infrastructure for ABC Melbourne remains today.The photograph documents a surviving element of this historically significant site and provides a record of its appearance at the end of the twentieth century.7729 - 3LO Transmitter Station Building Ashley Street Maidstone 1999 Photograph (Advocate 559.2).JPG3lo, ashley street, maidstone

A telegraph key or Morse key is a specialised electrical switch used by a trained operator to transmit text messages in Morse code in a telegraphy system. Keys are used in all forms of electrical telegraph systems, including landline (also called wire) telegraphy and radio (also called wireless) telegraphy. An operator uses the telegraph key to send electrical pulses of two different lengths: short pulses, called dots or dits, and longer pulses, called dashes or dahs. These pulses encode the letters and other characters that spell out the message.Metal device with black knob mounted on a wooden base. A plaque with printed text is also attached to the base.Printed: GIVE A SERIES OF DASHES INSTEAD / OF A STEADY EXPOSURE WHEN CALL- / ING FOR LIGHT, OR SHOWING LIGHT. / USE THE PLUG IN No. 1 / SOCKET AS LONG AS THE / LIGHT IS GOOD ENOUGH. / THEN CHANGE TO No. 2 THIS WILL / LENGTHEN THE LIFE OF BOTH BULB / AND BATTERY.morse code, communication, telegraph key, messages, pulses
