P.02 - Editorial

Editorial

First of all I want to thank you all for the wonderful reception you have given me and the effective help. Apparently hundreds of my friends, whom I have never had the pleasure of meeting, have shown themselves to be true friends by spreading the news, and it has travelled far and wide at great speed. One big result has been a tremendous increase in my mail and 'phone calls and what with trying to get out a bigger and better issue, and catch up with my correspondence, I have put in the busiest month I can ever remember. It has been good fun, of course, because it has been so successful. I don't think anybody minds working hard when they can easily see that they are progressing. Particularly gratifying has been the response to our offer of a technical query service by return mail, and to our offer of laboratory service, although both of these have added greatly to the amount of work to be done. Additional staff has been obtained, however, and from now on we should have little difficulty in keeping abreast of the work involved. It is with regret that I have to announce that a change has been found unavoidable in connection with our short-wave review. Mr. Alan Graham, who has conducted this section in such fine manner for some time has gone into camp and so will not be able to contribute these notes for future issues. My luck holds, however, and I consider that I have been most fortunate in being able to obtain Mr. L. J. Keast to carry on the work. Mr. Keast has been a prominent short-wave listener for years and a keen contributor to leading journals. We feel sure that Mr. Keast will carry on the short-wave review in grand style. Speaking of changes, you will notice a couple of new features in this issue, a page for letters to the editor, and a Hints and Tips page, contributed by Walter G . Nichols, one of radio's pioneer experimenters, a fine artist and a man with a keen appreciation of the finer points of radio theory and practice. Work in connection with the amplifier championship is way ahead of me at the moment as I have been so busy with other things. Keen interest has been shown however, and that is what matters most. Already I have hod several entries and bookings for seats, also applications for positions on the judging staff, and on the organising committee. These things should be straightened out in the course of the next few days, so if you have anything you want to say about the contest I'd appreciate a letter immediately. It's your contest and I want you to see that you get your share of the work, interest, and enjoyment. — A. G. HULL
