EDITORIAL

Again and again crops up the matter of the application of the morse code test as a gauge of a person's suitability to be granted an operator's certificate. In this morning's mail is a letter from a radio enthusiast who is undoubtedly a fellow of the type who would make the best possible use of a transmitting licence, and who has seen several years of service as a radio mechanic, with the R.A.A.F. But his doctor has given him strict orders that he is not to tax his nerves by attempting the strenuous concentration necessary to master the code. To some people the morse code comes easily, to others it is a nightmare. Strangely enough, it is not the intelligently dumb or the reckless irresponsibles who have the most difficulty with the code. For fifteen years past I have battled on this particular subject without making any noticeable impression on anyone, except to offend several people with an editorial I wrote for "Wireless Weekly" about ten years ago, when I said something about the morse code test being proof that a person has the mentality of a parrot, rather than proof of his ability to handle a transmitter. There may be justification for a knowledge of morse code by those who use the communication bands, but is there no chance of a relaxation of the Regulation for those who want a licence to operate radio-controlled models? - A. G. HULL.
