Morse Code is a method of transmitting text information using short and long signals (‘dots and dashes’). ...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.

Remains of webbing carry straps on back (see photo). ... Key Equipment Telephone Set and Morse Code Key ...Metal box with hinged lid containing Morse code equipment – batteries, bell, transmission key. Remains of webbing carry straps on back (see photo). This item has been modified from the original design. The item has a battery box located behind the Morse key but the original battery has been replaced by two rectangular 1.5 V batteries which were placed in the shelf below the Morse key. That shelf was initially intended to store the audio telephone hand piece which is no longer with the device. Hence, the final use of the item was as a Morse key only.Stencilled on outside lid (see photo): TELE SET D M (3 or 4 other indecipherable faint letters/numbers; likely "D.

Instrument Morse Code Key Set ...The battery powered set, which dates from the second half of the twentieth century, comprises two main components, the electronic keyer with a single lever for tapping, and a transmitter (?), both connected by a keying cable. Morse code was invented in the 1830s by American, Samuel Finely Breese by using electrical signals to quickly transmit information over a long range. In the early 1890s Italian inventor, Guglielmo Marconi improved the technology to the point where it became an essential device used for commercial and government purposes. The first practical applications were demonstrated with maritime messaging, where this simple mode of communication was seen as a timely replacement for the historic practice of signaling by flags, lights and foghorns. Cape Schanck has an earlier Morse code key, which is original to the lightstation (CSLS 0035), and Cape Otway has another early example although its provenance to the lightstation has not been formally verified (COLS 0074). The Morse code set has first level contributory significance for its historical value as an earlier communications device that has since been made redundant by more sophisticated technologies.Morse code key set.

... Lucas Morse Code Key...Morse Code Key - 10 Volt...Bushfire Radios Forests Commission Victoria (FCV) Morse Code Key - 10 Volt Lucas Morse Code Key ...After the 1939 bushfires, the Forests Commission Victoria invested heavily in a radically new communications network. After suffering some inevitable delays due to the war, radio VL3AA switched into full operation in October 1945 proudly beaming out 200 watts across the State. But by today’s standards, the technology was primitive and the reception poor unless the user was on a high point somewhere. The radio signal was "line-of-sight" and bounced between fire towers and relay transmitters across the mountains back to the District offices. The advent of solid-state electronics in the 1960s replaced the more delicate valve sets which enabled greater use of vehicle mounted radios. The Commission continued to research, develop and build new radios at its many workshops around Victoria. The network was supported by a large team of skilled radio technicians. The more secure and versatile State Mobile Radio (SMR) digital trunk system came into operation in about 1995. Upgraded Tait Radios were purchased in 2014 after recommendations of the 2009 Bushfires Royal Commission. But it was the convergence of separate technologies such as 5G mobile phones, high-capacity and light-weight lithium batteries, Wi-Fi, the ever-expanding internet, cloud data storage, digital cameras, GPS, personal organisers and hundreds of supporting Apps into powerful smartphones and tablets which revolutionised bushfire communications from the mid-2000s.

It was manufactured by blue point in the 1950s. The company was founded in the Sydney suburb of Erksville in 1936 by a German immigrant, Frederick Boyd Dirks who named his company F Dirks. The company produced Bakelite products such as ashtrays single strip heaters, and Morse key components, In 1946 the company named was changed to Blue Point products Pty Ltd. The name was inspired by the name “Blau Punkt” a German electrical supplier. in 1973 the company was purchased by Gerard Industries which was known for its line o Clipsal products, An item made in Australia for training purposes of new radio operators and is significant in that it is part of Australia's social history and shows the development of Australian electrical manufacturing.
