The "Radio Times"

F irst Issue This Week

T the end of this week the first issue of the "N.Z. Radio Times" will be available. We have great pleasure in introducing to the New Zealand radio enthusiast this new member of the family of radio publications now issued by ourselves. Really we feel quite proud of our "baby," and we are sure when the enthusiast has seen it he will forgive us. It is printed upon good paper, which means that illustrations are reproduced much more clearly than they can be on the rotary press on which the "Radio Record" is printed. Our feature article is a splendid long story of the early days of #roadcasting, told by Mr. L. Spackman, who is one of radio’s earliest associates. Mr. Spackman has a delightful style and readers of his article are assured of a very entertaining and informative hour. Other specials are an interesting interview with Charles Forrest, who was the operator of the first broadcasting station in Wellington. Mr. Forrest’s reminiscences are bright and humorous, the first of a series of articles on "Round New Zealand with the broadeasting ‘B’ Station," treating 1ZR, Auckland, and Mr. F. W. Sellens on "ive Years of Broadcasting." There is an interesting account of the new 200-kilowatt broadcasting station at Prague, and a resume of some points which may quite possibly be asked in the forthcoming Radio Servicemen’s Examination. Discriminating readers: will find the opinions of the radio trade in New Zealand on "What I expect of the Radio Board in the next three years" of more than passing interest. We wrote the principal dealers and distributors asking them this question, and their replies are bristling with interesting and, in many eases, controversial points. As a regular feature the page of "Jottings of Interest to the Beginner" should prove acceptable to most listeners. This is not an introduction to the science of radio, but is an account couched in terms of methods of improyjing reception which the average listener can understand. Of interest to the technical reader will be an account of valves and valve characteristics. In this article the writer presumes the reader has no previous knowledge of valves and explains how amplification takes place. He then goes on to explain the meaning of the more familiar terms mentioned iu valve characteristics and how they are obtained. He then works out a complete set of valve curves and shows the reader what each curve means and how to interpret the. valve performance from the curves. Then he gives the curve and characteristics of an actual valve. By studying this article anyone not at all familiar with valves will be in a position to interpret the average tables and curves. Probably the most interesting feature trom the enthusiast’s point of view will

be a description of the "DX Two,"

& modern two-valve receiver, comprising screen-grid detector and pentode. This set uses reaction, obtaining it in a novel way by a differential condenser used in the screening-grid circuit. The pentode is specially matched to the speaker by a transformer, and those who build the "DX Two" will discover that it is not misnamed. Log Section. "THEN there is the Radio Log Section, This dxers will look forward to with keen interest, and we hope \jhey will not be disappointed. There-‘are the usual dx features, and, in addition, we are starting this month a new fea-ture-"‘Notes and News From the Centres." Dx members are aware that secretaries are being appointed in each of the main centres, and it is their duty to keep the club notified of all doing in their district. This will be done per medium of their page in the "Radio Log," as we are calling the dxers’ section of the "Radio Times." There are many new and amended Q.R.A.’s and names and addresses of additional members to the Dx Club. Radio Digest. BALERS will find the "Radio" Digest" section, which goes out to them only, of great interest and value, Next Month. e SEVERAL interesting features are being planned for the next month’s "Radio ‘Times,’ and announcements will be made upon these in the near future. The technical department has an excellent receiver "up its sleeve," and before long the sketch details will be released. In future issues of the "Times" we intend to have a "Query Corner" somewhat similar to that of the "Radio Record." This will deal with queries in more detail than is possible in the "Radio Record," and will also specialise in difficulties encountered by constructors of "Radio Times" sets. Secure a copy of this month’s "‘Radio Times" at 9d and we are sure you will place your order for a regular supply. In these days we cannot afford to ¢verprint, with the result that those who do not get in early are almost certain to be disappointed. Observe that the publication date of the "Radio Times" will be the first of each month. We apologise for this issue being a little late, but as readers no doubt guess, this has been due to the extra work involved in the production of the 1932 "Radio Guide," but now that is out, we can promise the "Radio Times" regularly by the first of each month.
