Editorial

Post-war plans are popular topics for discussions, so let us not forget the place of radio. War-time radio has been responsible for tremendous developments which am not yet fully appreciated by all of us. Every plane in the bomber squadron keeps in constant touch with every other plane, as well as with its base; even the fighter pilots take their instructions by radio. Practically every unit of a modern mechanised army has its own transmitter and receiver. Tanks keep in constant touch with each other by radio, even the infantry battalions carry radio. All of which goes to indicate how radio can be applied to postwar conditions. Imagine the time which can be saved if all taxi-cabs carry radio and keep in touch with headquarters; if fleets of delivery trucks from the big stores are so equipped; as well as the fire brigades, ambulances, and the road patrols. Imagine the possibilities of radio transmitting as a hobby for the hundred thousand men who have been taught the theory and code in their army, navy or air force training. There is room on the air for at least fifty thousand radio "hams" and every prospect of them receiving official encouragement in recognition of the service they have given. In broadcasting there is ample room for development too, especially in the direction of television, and super high-fidelity sound on short-wave or with frequency modulation. Encouraged under the control of a man of wide vision and progressive ideals there is no limit to the possibilities of post-war radio development. Our only fear is that radio may be left in the grip of the P.M.G's Department, at the mercy of some old-fashioned official who sees in radio only a competitor to the telegraph and the telephone.
