lege, Nashville 5, Tennessee inquiring where he can buy a used light weight FM transmitting antenna and also a used frequency and modulation monitor. If you have these items for sale, or know where they are available, he’d appreciate hearing from you. _N A E B— A new and improved Television Test Film is now available! The new film is a 35mm and 16mm tele¬ vision alignment and resolution test. The conven¬ tional resolution chart has been retained and both films are produced according to rigid standards as specified by the SMPTE Television Engineering Committee. The films are camera originals which completely eliminates the possibility of printer error. The target is illuminated with exceptional care and recent tests on a sample have shown that the density variation per area is less than .05. The film is avail¬ able for immediate delivery through Society Head¬ quarters, 55 W. 42nd St., New York 36, New York. —NAEB— A report entitled Closed Circuit Television In¬ stallations in Educational Institutions has been pre¬ pared by the Joint Council on Educational Television and the Committee on Television of the American Council on Education. The report is dated July, 1958, and gives informa¬ tion on 133 closed circuit systems used by 119 edu¬ cational institutions. Class instruction over these systems ranges from first grade through college post¬ graduate. There is also a report on military closed circuit installations. Single copies are available free through the JCET to educational personnel. Bulk and business orders are 30 cents per copy. —NAEB— The map which fills the back page of this News¬ letter is one prepared as an exhibit to be presented at the FCC hearing on Docket No. 11997 which covers allocations between 25 and 890 me. It shows all non-commercial FM stations in the United States, a total of 164. We hope we didn’t miss anyone. We want to prepare a similar map for educational AM stations showing their coverage and directional patterns as well as a third map showing non-com¬ mercial educational television stations and their class B coverage. We’ll need data from the stations con¬ cerned for these proposed maps so we urge your co¬ operation when you receive our request for this coverage data. —NAEB— The 1959 National Convention of the NAEB will be held October 27-30 at the Sheraton-Cadillac Hotel in Detroit, Michigan. “Tape Recorder Directory—Each year Audio Devices, Inc. publishes a tape recorder directory as one of the issues of their magazine “Audio Record.” They have kindly provided us with some so that we may fill your requests for single copies. Just drop a card to NAEB Headquarters. —NAEB— Best wishes for a Merry Christmas and a Happy and Prosperous New Year! DECEMBER, 1958 5
