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.

This is a set of 26 photographs of Royal Australian Survey Corps (RA Svy) personnel from Central Comd Fd Svy Unit (Adelaide) on Aerodist survey operation - Project C4 in Eastern Arnhem Land, Northern Territory in 1967 (photos .4P to .26P) and in Western Arnhem Land, Northern Territory in 1968 (photos .1P to .3P). Photos of personnel were taken either at the operations base at Numbulwar or the main base at Gove (Nhulunbuy). RA Svy conducted nineteen Aerodist operations for 12 years from 1964 to 1975. Aerodist MRC2 was a tellurometer-based system adapted for aircraft to accurately measure distances between non-intervisible ground survey stations, using the aircraft as an intermediate station. Lower order geodetic results could be achieved by survey network trilateration. The measured distances between stations formed survey networks from which each station’s latitude and longitude was computed. Aerodist MRC2 was RA Svy’s major horizontal control survey tool for mainly medium scale topographic mapping (scale 1:100,000 Class A being spatially accurate to within 50 metres) in PNG, northern NT, north-west WA, Kalimantan Barat (West) Indonesia, Sumatra Indonesia, Gulf of Carpentaria and Cape York, QLD. In 1967, the Aerodist MRC2 Master equipment was installed in the aircraft featured in this set of photos, Executive Air Services’ (Essendon VIC) Grand Aero Commander VH-EXX. It was the same aircraft type and company contracted to Division of National Mapping for Aerodist MRC2 surveys. From July to October 1967 the aircraft was attached to Central Comd Fd Svy Unit (Adelaide - Major Don Ridge) on Project C4 eastern-Arnhem Land NT, where 317 Aerodist lines measuring 17,300 line miles were successfully completed. This was the most productive Aerodist project thus far. The most common helicopter used by RA Svy up to 1972 was the civilian Bell 47G-2 and the Sioux Light Observation Helicopters (LOH), the Australian Army’s equivalent featured in this photo set. These light observation helicopters had a limiting load carrying capacity of up to about 500 pounds. By comparison, one Aerodist team including two people weighed up to 1,500 pounds. In 1968, after completion of the Kimberley Aerodist Operation project, the Aerodist system in VH-EXX was immediately deployed to western-Arnhem Land NT for Central Comd Fd Svy Unit (Adelaide - Major Don Ridge) to complete the mapping control across northern NT from mid-July to October. The Aerodist MRC2 Remote antenna seen in Photos .24P to .26P is mounted on a 20 foot pole tower. The antenna direction was controlled by wires/ropes to the two arms under the dish at right angles. The antenna elevation could be changed to the vertical for aircraft height checks as seen in photo .25P. Source: Royal Australian Survey Corps – Aerodist Years 1964-1975 by Peter Jensen.

This Favag Timer apparatus was a part of the first electronic control system -(1960's), in Victoria), which worked using telephone stepping selectors to convey a change in voltage providing a regulated pulse from the control centre(Mount Beauty) to the remote Power Stations opening and closing (stop/start) of various devices at the Power Station and a return signal confirmed the action taken. Testing of this unit was carried out using a "dummy" device at the remote Power Station so as not to disrupt the power plant's operation. This timer was one of many electrical apparatus connected to the large SEC Victoria Hydro Scheme's electrical power producing generators. These generators are powered by the hydro force of "stored" water at a higher altitude. The establishment of both the NSW and Victorian Hydro Schemes was achieved from the early 1900's to the 1960's. At this point in time the need for additional power sources to quench both an industrial and domestic demand for electricity was purely an economic and not and environmental (carbon reduction) factor. This hydro scheme was instigated by "the Government of the day" as a bold move and was the major force of the World War II refugee and "technical" workforce,inclusion of skilled and unskilled, migration into the Australian environment. Although this mass "invasion" of workers with families was thought of in some circles as intrusive, the expansion of population post war years and its integration into the Australian rural sector, produced the multi- lingual multi-cultural diversity of later years.This Favag Timer was one of the crucial pieces of equipment that made it possible for the Mount Beauty Terminal Station to control the operations of these Power Stations; McKay, Clover, West Kiewa Power Stations and the Dederang Terminal Station.This aluminium and anodised "FAVAG" (pulse) timer is fastened to a base structure which comes with its own metal cover that is fastened by two metal hooks. From the top of these hooks runs a thick leather "carry" strap.The instrument, itself, a small "micro motor" at one end tape feeding spool on the other. Aluminium metal structures offer a preventative barrier against any electronic spikes from static electricity sources. There are two toggle switches to the bottom right hand side and twelve coloured "pin" connection points.There is a sliding access sleeve which exposes a circuit board.with various leads fastened on each side. In front of one of this slide are two "screw in" fuses, spare fuses are in a small envelope taped above. Circuit diagrams are etched white on black background on the top face of the main structure. At the base of the back section is a two pronged input terminal. There is a fine black rubber layer (cushioning) for the mian top cover.On the cover fastened with two rivets "FAVAG" underneath in small print "Fabrique d'appareils electriques S.A." underneathe "NEUCHATEL-SUISSE". on one end is a "STATE ELECTRICITY COMMISSION OF VICTORIA" metal label screwed on.The back label has manufacturers' type and model number.sec vic kiewa hydro scheme, alternate energy supplies, alpine population growth
