There is considerable talk about the causes and cures. In the latest issue of "Radio and Hobbies," my one-time protege, John Moyle, makes no apology for saying that "there is a lack of drive and imagination among far too many radio firms." Some advertisers are saying that there is a falling off of interest in technical radio. I can assure them that this reckoning is quite wrong. Our subscription list was never longer, our sales more than 300 per cent, greater than pre-war. The fact is that these readers are thirsting for something interesting, something new. Technical journalists are doing their best to quench this thirst, but it is a hopeless task when component manufacturers won't produce any new lines, or even good ones. What inducement is there for anyone to build new receivers when the finished article will have little or no advantage over the many sets already littering the workshop? Fortunately, there are one or two firms still active. For example, see details of the new Aegis tuning unit in this issue. In last month's issue we started to deal with the subject of what is wrong with the radio set business, and we have had many letters of congratulation on this effort. We hope to follow up in next month's issue. It has been thoroughly confirmed that a great many set designers are impractical in their outlook, and out of touch with their public. Many of them would learn a lot if they put in a few months on the bench in a radio repair department. — A. G. HULL.
