EDITORIAL.
The future of the radio enthusiast who wants to experiment with transmitting appears to be assured. Those who want to own and operate their own transmitters should receive every encouragement and there is every evidence that this will become official policy in the immediate future. There is even a possibility that "hams" will be back on the air before the war is completely cleaned up. Restrictions will be unavoidable, of course. Considerable control will be necessary to prevent the ether being cluttered up, but it must be gratifying to hams to know that their war effort has been fully appreciated. Modern warfare is a matter of the finest of technicalities and it has now been revealed that one of the biggest factors in the winning of the Battle of Britain was the successful application of radiolocation technique, or radar, as we now call it for short. Just how many "hams" were directly connected with the development and application of radar is not known, but it is a pretty safe bet to say that probably 90 per cent gained a lot of their practical knowledge from radio experimenting. Now, with the return of peace, the logic of encouragement is clearly evident. Recently, several committees in the United States have been considering proposals for the allocation of post-war frequencies. It is noteworthy that not one committee has suggested any curtailment of the amateur bands and the only point in doubt concerns just how many additional bands should be handed over to the "ham." One suggestion is to add a "ham" band at around 15 metres and this would appear to be a most excellent one for DX work. A. G. HULL.
