Radio broadcast .. (1922-30)

'32 RADIO BROADCAST service of this most important apparatus which otherwise would have been greatly retarded owing to the badly tangled patent situation among the American radio concerns themselves, and it resulted in the American radio services being freed from the handicaps which would otherwise have greatly retarded the forward march of progress in the development of the radio art in the United States. The Navy in other ways gave its best advice and cooperation to the newly formed Radio Corporation of America for reasons which are obvious from the foregoing. The cross-licensing on the part of the American Telegraph and Telephone Company, General Electric Company and Radio Corporation of America, together with our extensive and efficient manufacturing facilities for radio apparatus, and our extensive and widely separated chain of shore radio stations, has placed the United States in an unassailable position as regards all matters pertaining to radio, the immense value of which from the point of view of our humanitarian efforts, the national defense, our commercial interests and the nation's prestige throughout the world will undoubtedly be more fully realized as time goes on and further developments are made in the radio art. Subsequent to the arrangements having been mutually made between the above companies, the Westinghouse Manufacturing and Electric Company and the Tropical Radio Company were also taken into the agreement. It may be stated that, as a direct result of the conference of April 7, 1919, American radio became the most powerful in the world, whereas prior to that time the British Marconi Company must have felt that their hold on the world in this respect was secure. The really important feature, however, is that, as a result of that conference, all of the radio interests of the United States were for the first time placed entirely in the hands of American citizens. The Navy pointed out to the newly formed Radio Corporation that it should be to their interest to have connections with South America, in order to extend the allAmerican chain of high power stations, in the interest of the advance of trade and cooperation between North and South America. The British, Germans, and French had secured concessions in South America which made this situation a very difficult one to handle, but through able management a compromise was effected, and, as a result, the Radio Corporation has entered into an arrangement with the British, Germans, and French in South America, while yet keeping control of the advantages already gained as outlined in this article. We are now entering upon the era of radiotelephony, the future developments in which and the results therefrom no one can foresee. The possibilities for good or for evil are so tremendous that it obviously is of primary importance that we guard our pre-eminent position in the radio world and maintain the lead which we now enjoy. Radio Personalities in R. A. HEISING The Man Who Solved the Problem of Sound Modulation by Radio By EDGAR H. FELIX, A. I. R. E. SiLDOM does an inventor perfect his discovery and later realize its importance. The process is usually reversed and of four steps: first, the germ of an idea, second, a crude model; third, the acclamation of his discovery to the world; and fourth — if he ever reaches that stage — the long and difficult process of perfecting the idea. In this Reginald A. Heising, the inventor of the modulation system which makes broadcast music a practical possibility to-day, is the exception among a hundred great inventors. His discovery removed what had long been
