Morse Code is a method of transmitting text ...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.

Telephone Set and Morse Code Key Equipment Telephone Set and Morse ...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 The item has a battery box located behind the Morse key but the original battery has been replaced by two rectangular 1.5 V batteries which were placed in the shelf below the Morse key.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.

Morse code was invented ...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.

... messages in Morse code in a telegraphy system. Keys are used in all ...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.

Morse key, C 1930
... telegraph telegraph key morse code ADMY.PATT No 7681 KEY MORSE SERN ...The Morse telegraph system had its beginnings in 1836 when Samuel Morse, Alfred Vail and Joseph Henry developed an early model of the system. There are a number of variations on the machine but the operating system is very similar in all and the language is a standardised international code which has been in operation since the 1860's. Morse code consists of five elements, dots, dashes, and gaps of one , three and seven units in length. It is still in use to this day and has been applied to other systems of communication such as amateur radio, mobile phones and communication systems for disabled people. This particular telegraph key possibly has post office or naval origins.Morse code was an important invention in world communication systems and this machine therefore has important social and research significance. It is useful as an interpretive item.This instrument sits on a black rectangular base of black bakelite. The mechanism ids held in place by three larger metal screws and two smaller ones on the upright section from the base.The movable part is metal with the attached handle a similar black material as the base.ADMY.PATT No 7681 KEY MORSE SERN PL 23780 Rocker Front contact.

Used at 55 OBU Birdum and Gorrie Wireless telegraphy stations, and sent over 1.5 million weather forecast groups in 15 months. Then used at 57 OBU Alice Springs Airport until April 1946"I bought thie unit in Melbourne in 1944 while training at Point Cook RAAF Signal school as a wireless telegraphist. With my posting to 55OBU (operational base unit) at Birdum and Gorric Wireless telegraphy Stations broadcasting weather forecasts in morse code for the south west Pacific area, it was used continually, sending over a million and a half weather forecast groups over 15 months.

Functional object - Morse Training Key, 1950s
The set consisted of a key battery and buzzer it was used for training potential radio operators in the Morse code. 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.

Equipment - Morse key, Postmaster-General's Department, circa 1920
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
