The box is cleverly designed to give quick access to the parts inside, having a lift-up lid and a pull-down front. The components within appear to be a portable radio, power supply or power converter with batteries and a charger. The attached leather strap makes the equipment easily portable. The portable power supply is significant for representing part of the evolutionary change in communications. The unit connects the use of power and radio for communication with the ability to save the power in power packs or batteries, or to convert the power from one form to another.Power supply, portable, electric; circuits can be Parallel or Series. Batteries (6) fitted into a square wooden box. Box has two catches to secure the lid and two catches to secure the drop-down front. Holes have been drilled around the edges of the lid and the top of the base. Inside the front panel are two copper coils, switches and connectors. Leather carry strap attached.

An emergency position-indicating radio beacon (EPIRB) is a type of emergency locator beacon, a portable, battery-powered radio transmitter used in emergencies to locate airplanes, vessels, and persons in distress and in need of immediate rescue.Since the inception of Cospas-Sarsat in 1982, distress radio beacons have assisted in the rescue of over 28,000 people in more than 7,000 distress situations. In 2010 alone, the system provided information used to rescue 2,388 persons in 641 distress situations.

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 contraption is thought to have been developed in the FCV radio workshops at Surrey Hills. It's basically a STC vehicle radio which has been mounted on a backpack frame and powered by a heavy lead-acid battery. The backpack frame was manufactured at the Altona fire equipment development centre. A considerable number of these radio units were made and distributed to the field.bushfire, radios, forests commission victoria (fcv)
