Black and white photograph, Local photograph. Original of this scan held by Nhill Historical Society, Aeradio Building c1937
This building is still intact at the Nhill Aerodrome. Some of the infrastructure is also in place or can be evidenced by its foundations.The Aeradio building was built on the present aerodrome in 1937. This was one of only sixteen buildings of this type built across Australia and it housed radio communications and guidance equipment. The building and its equipment were part of a comprehensive system of radio towers, signalling and meteorology equipment aimed at providing safer navigation for aircraft travelling throughout Australia. The facility closed in the 1960sThis photo is significant due to it having been taken soon after the building was constructed. It is the earliest known photograph taken on an open to the public day before the receiver aerials were erected.The Aeradio building was built on the present (2012) aerodrome in 1937 or 1938. This was one of only fifteen buildings of this type built across Australia and it housed radio communications and guidance equipment. The building and its equipment were part of a comprehensive system of radio towers lights and signalling equipment aimed at providing safer navigation for aircraft travelling throughout Australia.

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 -

Photograph (item), The Telegraph, James Melrose with aeroplane My Hildegarde, 16 October 1934
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
