Color Trends & Briels: Color servicing problems are rapidly being reduced, RCA Service Co.’s E. R. Klingeman told NARTB engineering session this week. “Most problems really do not exist,” he stated. “We’re able to go ahead with almost the same ease and facility of black&-white.” He stated that 18,718 servicemen have attended RCA clinics.
He reported that there are very few locations which can’t receive color adequately. Asked how far color can be received, he said he gets it satisfactorily at his farm — 80 mi. from stations.
Noting that RCA is accentuating its final testing of sets at factory, Klingeman said RCA hopes soon to deliver sets that require no more than demagnetizing in more than 50% of cases.

BBC’s development of compatible color on Britain’s 405-line system was attacked this week by Sir Robert Renwick, pres, of Radio & Electronic Component Manufacturers Federation. He charged BBC is spending “vast sums of money” on a system which can only be manufactured for the home market, “making the cost of manufacturing sets for export on 625 lines prohibitive. He called for concentration on European 625-line standards in color development.
Electronics Reports: wireless paging system which uses no radio frequencies, and therefore isn’t subject to FCC licensing, is ready for production and marketing by Philco. As demonstrated this week at NARTB convention in Chicago, tiny “Audipage” will get first large-scale use at Democratic and Republican conventions, when ABC will equip 30 of its roving commentators and floor men with the receivers, so that they may receive instructions directly from control points without use of connecting wires or cables.
Audipage is a 3-transistor magnetic receiver, the size of a cigarette lighter, powered by tiny mercury cell. It will operate only within the restrictions of a single wire “loop” strung around the perimeter of an area. An entire building can be included in a loop, which is connected to an ordinary amplifier. By magnetic audio induction, the oneounce receiver picks up signals anywhere within the wire loop. Only frequencies involved in system are audio frequencies. Philco will market the device for paging systems in public buildings, hospitals, theatres, factories, TV-radio stations, etc., where conventional intercom systems are impractical. Price for each Audipage unit, with hearing-aid type earplug, will be $100-$150.
At Chicago demonstration, fidelity of Audipage was extremely good, with the single bell-wire loop strung around room, and connected across speaker terminals of TV set, and later to output terminals of 20-watt amplifier. Volume was high, and the tiny receivers even were equipped with tone control. No transmitting equipment is required, other than a conventional audio amplifier.

Third transistor price cut in 14 months was announced this week by GE, which reduced prices 22-53% on 5 types of high frequency transistors used in portable radios. New prices range from $1.50-$1.80 to manufacturers. Company also announced prices of 10 new audio amplifier transistors for home radios and hi-fi equipment, ranging from $1.40-$2.35 each.
Heavy foreign interest in closed-circuit TV is reported by Dage TV div. of Thompson Products, which this week announced appointment of C. 0. Brandes Inc., Cleveland, 0., to handle export sales in Europe, Africa and South America.
