[edit | edit source]EDITORIAL.
Of tremendous interest to all radiomen and to the radio trade as a whole are the announcements from both England and America that the use of the walkie-talkie in peacetime is to receive official encouragement. Elsewhere in this issue we give details of the American plan, which sets out to encourage manufacturers to market cheap transmitter-receivers for civilian use. Applications of walkie-talkie will become accepted as just another modern convenience. The wavelengths allotted for use with walkie-talkie may appear startling to those who have not been in close touch with recent radio development. The use of wavelengths below one metre calls for special technique, but there is nothing to be afraid about and we look forward to that not too far distant day (we hope) when we will be running constructional articles telling you how to build and operate your own transmitter for use on this band. It is expected that some sort of licence will be required, but no qualification tests, such as a theory examination or a speed test in morse code as was, and probably will be, required for the licence to operate an experimental transmitter working on the longer wavelengths. It should be clearly understood that there is no question of the walkie-talkie licence replacing the amateur experimental licence, and, if everything turns out as we have every reason to hope, the two classes of transmitting licences will be complementary to each other, co-operating to create even greater interest in technical radio than ever before. The prospects are exceedingly rosy.
