A recent gathering of the Antique Wireless Association, a group of amateur radio historians and collectors, paid tribute to pioneer publisher and radio manufacturer Hugo Gernsback. Among the exhibits of coherers, magnetic and electrolytic detectors, and early microphones, were many pieces of equipment manufactured by the Electro Importing Co., an early Gernsback enterprise. During the luncheon held in his honor, Mr. Gernsback addressed the group by means of a special tape recording. He stressed the need to preserve historical records and artifacts and spoke of his desire to see a museum devoted entirely to communication. Distinguished guests included: Elliott Sivowitch, assistant to curator, and Dr. Bernard Finn, curator of electricity, both of the Smithsonian Institute, and Frank Davis, curator, Ford Science Museum. Baseball fans saw a further innovation in TV engineering used in last year's World Series. Interesting or tricky visual action was recorded and played back later in slow motion - electronically. The technique made use of MVR Corp.'s VDR 250 Videodisc slow-motion recorder, which can record video signals on a magnetic disc. When replayed, action may be slowed or stopped completely, or it may be viewed at medium-slow motion as well as at normal speed. After recording, the machine can be cued for replay in less than half a second.
Research continues in attempts to develop a practical electric auto to meet today's needs. General Motors has installed silver-zinc battery packs, SCR's and specially designed AC motors in its experimental Electrovair II. Performance is reported similar to that of a gasoline-powered Corvair except for cruising range. The electric car must recharge its batteries every 40 to 80 miles, vs a range of 250-300 miles for gasoline-refill range of a standard car. A regular 1966 Corvair chassis is used, but Electrovair II weighs 800 pounds more than its gasoline-powered cousin. Another experimental vehicle being tested by GM is Electrovan, a van truck using tanks of liquid hydrogen and oxygen as an electric fuel cell. Such a power source is still expensive and not yet practical. Commercial Radio to Start in Britain A new popular-music radio service with commercials will be started soon by the government of Great Britain. The new agency will be known as the Popular Music Authority (PMA) and will be financed entirely by advertising revenue. This is in contrast with the practice of the 44-year-old BBC, the government-controlled monopoly that has furnished Britons with commercial-free radio fare until now. PMA will broadcast on broadcast-band channels now used by BBC's Light Programme, one of three BBC services. Chief reason behind the decision was the nagging existence of "pirate" stations which operate transmitters from offshore ships or abandoned gun forts on reefs, selling time and broadcasting modern popular music. These stations are to be outlawed. The new radio service has a precedent, however - the 12-year-old ITA (Independent Television Authority). BBC television is commercial-free, like its radio service, but ITA carries advertising on its channel. More Shortwave Broadcasting For the first time in 4 years, conditions have opened up on the 11-meter shortwave band. Signals are being received on the 25-26 MHz international frequencies, due to increased sunspot activity. Not only will overseas broadcasts be available for SWL's, the 27-MHz Citizens band will undoubtedly be plagued by skip interference. FM listeners in the New York City vicinity can hear Radio Peking, Radio Moscow and Radio Havana without a shortwave receiver. New York's WRFM (105.1 MHz) tapes English-language news and comments from these three Iron-Curtain SW stations for playback to their audience. The excerpts are heard intermittently from 8 to 11 pm nightly. WNYW, WRFM's SW affiliate, returns the courtesy by broadcasting features about the U.S. to its overseas listeners at the same time.
