## P.02 - Editorial

Editorial . . . December, 1950
IN this composite December issue, it is our desire to make known — nationally wide — all about the important transformation of "Australasian Radio World" to "AUSTRALIAN RADIO & ELECTRONICS". Last month you were informed that "Australasian Radio World" had been taken over by a new Company, so we have pleasure in taking this opportunity of introducing ourselves to old friends, and new. For your information our Associate Company — Radio & Electronics (N.Z.) Ltd. — has been producing "R. & E.", a New Zealand monthly magazine since April, 1946, and, for some time, this journal has been imported to Australia, wherein it has enjoyed a highly esteemed reputation for the practical manner in presenting technical and scientific literature to its readers. As the circulation of "R. & E." has increased tremendously here, it was felt that, if the journal was produced in Australia, re-edited to suit Australian conditions (whilst maintaining the same high technical standard), we would be in a more favourable position to solicit local advertising from the Australian Radio and Electrical Industry, and thus be able to produce bigger and better issues, which would be mutually beneficial to all concerned — especially our readers. Also, in taking over the rights of "Australasian Radio World" — an old-established journal — and incorporating it into the new "AUSTRALIAN RADIO & ELECTRONICS" it is now possible for us to publish a combined periodical, retaining the best features of both. As an entree, shall we say, to the new combined "R. & E." our Company has just released on the market here, a new publication known as "THE R. & E. DIGEST OF CIRCUITS" Australian Edition — which, in progressive handbook form, covers everything from the simplest Crystal Sets to Multi-valve Receivers, Audio Amplifiers and Test Equipment. Although it is only "just out" on the bookstalls, we greatly appreciate the commending interest displayed to date. Next month, a new year commences — so does your new journal — wherein many and varied topics will be covered, with special attention being paid to a PRACTICAL experimental TELEVISION PROJECT for home construction, by the production of images on a Cathode-Ray Tube Screen, without the use of costly camera tubes, such as Iconoscope, Emitron, Image Dissector, etc. Our close liaison with New Zealand, and other overseas tie-ups, assures Engineers, Servicemen, Dealers, "Hams" and Hobbyists, that our articles will bring to them the latest developments for the advancement of Radio and Electronic knowledge. In conclusion, we wish to extend our sincere thanks for your past patronage, and trust you will remain one of the new Journal’s ardent followers . . . for we shall be "on the beam" . . . "Looking After Old Friends — And Looking Forward to New". The Editor and Staff of Australian "Radio & Electronics" can offer our readers and advertisers, no better wish at this momentous time, than that they share with us, the old happiness of Yuletide and the achievements of the approaching New Year and the New Era it brings. — LAY W. CRANCH.
