Wireless Set FS 6

The Wireless Set FS6 was developed in 1939 as an in-house project, in parallel with the development of the Wireless Set No.101, by Amalgamated Wireless (Australasia) A.W.A. in Sydney. The decision was apparently that a much more powerful set could be produced for very little size or weight penalty. The Australian Army showed little interest, however a considerable number were sold to India and subsequently used by the British in the Burma campaign. When Australia became under threat of invasion in 1942, Norforce (Curtin's Cowboys) was formed to patrol the mostly uninhabited Northern regions of Australia. The Wireless set No.101 had insufficient power and the Wireless Set No.109 was too large and heavy, thus the FS6 was produced to fulfil the requirement of providing communications for the Northern patrols. Ranges up to 30 miles could be archived using a vertical aerial and much greater distances using a horizontal wire aerial.
Power source, external 6 volt lead-acid battery. The high tension is provided by the external vibrator power supply. Frequency coverage, by master oscillator, 4.2 to 6.8 Mc/s. Average output power, 8 watts c.w. and 4 watts voice. Modes, voice (a.m.) and morse (c.w.). Number of valves, 5 in the receiver and 3 in the transmitter. The output valve is the ubiquitous 807.
