GUEST EDITORIAL

In New York recently the Chairman of the Federal Communications Commission warned amateurs, pointing out that the frequencies between 4 and 25 megacycles are very much in the spotlight. Following on this, "Radio News" (U.S.A.) says "— that brings us to the topic at hand; the conduct of many amateurs who are abusing their privilege to operate. The QRM situation becomes worse each day, yet many 500 watt transmitters can be heard emitting strong DX signals when merely talking cross-town. Such operators are doing little to enhance the art of Amateur Radio. When the chips are down they will only have themselves to blame if they come out on the short end of the deal— Atlantic City is sure to show pressure from foreign representatives who want amateur frequencies reallocated — every amateur should take stock of his own operating practices and make sure he is not open to criticism — it is the personal responsibility of each amateur to look jealously upon the safety of his hobby — there are many interests seeking any type of ammunition which will destroy our hobby." Those words of wisdom may well apply to this side of the Pacific, as those who listen know full well. In this part of the world there are loud-mouthed individuals who are endangering the whole future of amateur radio by spouting anything but the correct atmosphere into their microphones. There can be but one end to such malpractice. When shortwave listeners write in indignation to the Authorities it is more than obvious that the public takes note of the undesirable features of our valued hobby. — D.B.K.
