Following the usual routine, these statements have in due course been denied, and counter-statements have been issued. But where there is smoke you usually find fire, and so people gain the impression that there must be something to this frequency modulation business. The talk about frequency modulation has caught many radio engineers "on the hop", and we have been inundated for the back numbers in which the subject was dealt with, but these are no longer available. We have not had time to get a full story ready for this issue, but we plan to cover the whole subject in detail in next month's issue, including the possibilities which the scheme may open up. We do not under-estimate these possibilities, but at the same time we feel sure that they will take a considerable time to reach fruition and there is not quite as much need for a rush as some of our readers seem to feel. First the war has to be completely cleaned up, then the plans have to be laid, and we cannot imagine that frequency modulation will be a completely established service until at least a couple of years after the cessation of hostilities. In the meantime, radio technicians will have ample time to become thoroughly acquainted with the new technique.
