DEVELOPMENT IN RADIO MORE THAN SKIN DEEP.

The Pageant of Progress. While radio's pageant of progress may be grasped superficially by even the most casual observer by a glance at the receiver of 1923 and 1924 alongside the complete though compact console of 1930, one who wishes to know the true story of the remarkable progress made in radio in the last six years or so must go beyond the obvious. Development in radio is more than “ skin deep.” The fact that much which is not seen or asked about is highly important is obvious when one considers hadio engineering progress for the last six years expressed in the improved reproduction and in the longer life of 1930 receivers as compared with predecessors. Durability Important. Not onlv “ How does it sound?” and “How does it tune?” are important questions to-day, but " How long will it last?” With quality of reproduction and general operating characteristics well advanced on the road to the ultimate ideal of perfection, thousands of buyers are to-day investing their money in a radio receiver with every intention of using it for years and years. That radio receivers are now better built than ever before is apparent from the fewer service calls, fewer breakdowns. In fact, major trouble with a well-designed and well-manufactured set is a. rare occurrence. Save for the occasional replacement of a va.lve, modern radio has dependability little short of amazing, considering the hundreds of component parts involved, the intricacies of circuit and last, but not least, the human element, both at the factory and in the home. A Longer “ Life.” Just as the average lifetime of a human being has lengthened, decade by decade, according to life insurance statistics, so the life of radio receivers has been iifcreased and assured as the engineering pageant of progress has continued. The engineering staffs of several large concerns—notably the wellknown Rogers—estimate that with a reasonable amount of care their product is gpod for a lifetime. Valves have to be renewed as the years roll by, but, to all intents and purposes, it is certain that the radio set’s days of usefulness are the eoual of its owner’s lifetime. Certain parts of the modern radio set are built with the precision of a clock, yet the housing of the more delicate parts of the receiver and the over-all chassis assembly is construction that brings to mind " built like a battleship.” Improved Design. Improvements In design, which to the buying public may seem relatively unimportant, or even pa»ss unnoticed, have played a highly important role in radio’s development. The combining of perfected details, a majority of them concealed inside the cabinet, has proved of premendous value in simplifying receiver operation and in lengthening the life of the set. It is not difficult to recall the “ bread board ” type of receiver construction universally used by amateur set builders and manufacturers prior to 1924. Discarding all wood in chassis and framework, the complete metallic chassis framework was introduced. The advantages of an all-metal framework are obvious, when one considers the abundance of parts which must be supported and held in place, certain of them in exact relation to one another. One-Piece Chassis. Construction of more substantial radio receivers then took an important step forward with the introduction of the first chassis type construction in which the operating element of the receiver was built into one mechanical unit, the outside casing being used only as a housing. Total shielding also ha 3 been introduced, an innovation which has since become universally used in the building of efficient receivers. To assure stability, both electrically and mechanically, the use of metal as a shield has won a lasting place in radio manufacturing. From long telephone experience radio engineers borrowed the telephone switchboard type of cable wiring which has been used in all receiver designs Since 1924. The advantages of this type of wiring, as learned from telephone work, are many. It allows a fixed system of electrical connections, which, once tested and found satisfactory, can be used as standard with the knowledge that intercircuit actions have been eliminaed in production. As a later expansion upon the complete metal chassis framework engineers introduced the one-piece receiver chassis, mounting on one metal base all apparatus, including power plant equipment.
