BASIC ABC NETWORK REPRESENTED BY H-R REPRESENTATIVES ABCs in Demand EDITOR: "The ABCs of Radio and Television" in your current issue is a most interesting and helpful outline. It would have permanent value as a brief reference manual. By any chance are you planning to reprint it in the form of a booklet or pamphlet? W. S. Harvey Gray & Rogers Adv. Philadelphia EDITOR: Last night I missed all my favorite NBC radio and television shows reading your very informative and interesting "The ABCs of Radio." This is the story I've been looking for — in one place — for the past four years. Thank you. If reprints are made available I could easily use 25 copies. Robert M. Adams Director of Press and Promotion WRC-WNBW (TV) Washington, D. C. EDITOR: I thought that "The ABCs of Radio and Television" in your March 30 issue was an excellent summary. How about making this available in reprint form? If you do, I'd be glad to order some copies. They would be very useful reading for students. Robert M.

A., Too EDITOR: Congratulations on the ("How to Set Your Sales Talk to Music") article by Phil Davis appearing in B«T Feb 16. It was a pip, and I am going to have it translated to pass along to the lads in the radio department. . . . Bucky Harris, Radio & TV Grant Advertising South America Who's on First? EDITOR: In your issue of March 23 you published a comment by Mr. William S. Halstead on the FM multiplex system announced by Mr. John Bose and myself. Mr. Halstead claims a priority of two and one-half years for the Multiplex Development Corp. and the Crosby Laboratories in the multiplexing of FM signals. From an article in the November, 1950, issue of Electronics describing Mr. Halstead's demonstrations, it is clear that his equipment employed the system of FM multiplexing first used by me on April 22, 1935, when the programs of the NBC Red and Blue networks were transmitted simultaneously on a single carrier from the Empire State Building to Haddonfield, N. L, a distance of 85 miles. The arrangement of apparatus then used was described in my Institute of Radio Engineers paper published in May, 1936, and in my U. S. Patent #2,104,012 issued on Jan. 4, 1938. While the original system as described in these publications multiplexed facsimile from New York to Haddonfield successfully and worked well on aural transmissions according to the standards of the time, it did not meet the rigid cross-modulation requirements or signal-to-noise ratios of present day FM transmission; hence the new system of transmission was devised. This system, while proceeding from Time Buyers can save time by using WJBO's booming Baton Rouge market For instance, population is up more than 250% in the last decade.
