Editorial

To some outsiders it is difficult to understand the inspiration which motivates the radio enthusiast. Business acquaintances are amazed at the circulation of "Australasian Radio World." They cannot see why it sells so well at a time when radio parts are difficult to obtain, set construction is controlled and, generally, conditions are adverse for the experimenter. At the moment our sales are more than double the figure they were in 1939, and our subscribers number four times as many. What is the reason? You know the reason as well as I do. Radio is interesting. Reading about circuit developments is instructive and enjoyable. With simple equipment and a few "junk" parts it is possible to carry out practical experimenting which has excitement, even thrills for the keen radioman. Routine repairs of broken-down sets is not hum-drum work. In most cases it calls for the skill of the fictional detective, tracking down the trouble by careful analysis of clues which point the way. Sometimes the puzzle is quite baffling and the alert radioman pursues a most enjoyable hunt to locate the culprit component. Considering the practical angles only, the hard-headed realists have long pointed out that you can buy a radio set almost as cheaply as you can build one. But have you ever known anyone to derive so much enjoyment from a factory-built set as he gets from one built with his own hands, adjusted to suit his own taste and inside which he can visualize each component "doing its stuff" as the signal passes from aerial to speaker? The more we think of it, the greater is our faith in the future of the technical radio enthusiast.
