Radio broadcast .. (1922-30)

898 Radio Broadcast DR. S. PARKES CADMAN Pastor, Central Congregational Church, — Brooklyn " The scope of my Sunday broadcasting has been greatly extended. . . . Thousands of letters of appreciation come to me from the Eastern States. And when I visit the cities, towns, or villages throughout this vast region I not only meet people who listen regularly to my sermons but who are familiar with my voice. " We are coming to understand more fully the possibilities and limitation of broadcasting. It is a fascinating problem which well repays study and analysis. If one uses the radio merely to preach special doctrinal views he will fail. On the other hand, if he uses radio to broadcast the great basic principles of religion and of the welfare of the world, he finds in it an agency of unprecedented value." © New York Times. now that large water-cooled triodes could effectively replace the arcs, and nowthis change is actually going to take place. Four 20kilowatt triodes operating in conjunction with each other to feed power into the antenna will replace a 3OO-kilowatt arc and will permit more satisfactory and reliable communication, according to the engineers responsible for the new installation. But from our standpoint, the beauty of this new triode outfit to replace the arc is due to the absence of "mush". The oscillating vacuum tube is practically free of those spurious oscillations which are responsible for the great interference which the arc causes, and for this alone the radio listeners are truly grateful that the Government is to scrap its antiquated arc transmitters and to keep in line with the march of radio. Hoover Not For a Radio SalesTax RECENTLY a Washington dispatch, which at once received wide publicity, stated that in an interview Secretary Hoover had proposed a two per cent, sales tax to support radio broadcasting. Such a proposal at once brings up all sorts of difficult questions, such as, how to enforce the collection of the tax, and still more difficult, how equitably to distribute it. So it seemed that the eminent engineer-Secretary was becoming more of a theorist than an engineer. The truth was, however, that the Secretary did not make the suggestion attributed to him, neither was he in favor of agitation in behali of such legislation. We believe that a sales tax or a licensing scheme is not the way that the cost of broadcasting is to be met in America. We have yet to find it. Interesting Things Interestingly Said \A7ILLIAM A. BRADY (New York City; * » theatrical producer, speaking about the recent broadcasting by stars of the Metropolitan Opera Company, and others): "Radio constitutes the greatest menace the theatre has ever faced, and so far as I know, the theatre is doing nothing whatever about it. I am seated now in a room with a group of people and we are listening free of charge to a concert which I can only describe as gorgeous. Why should any one be foolish enough to go to a theatre under such circumstances? The trouble is not with those who sit at home and hear McCormack and Bori; the fault is entirely with men who control the theatre. "We engage these various artists and pay them to work for us. Why should they be permitted to ruin our business by giving free radio entertainments on the side?" P\AVID SARNOFF (New York City; vice*-^ president and general manager, Radio Corporation of America, speaking about coming events in radio): "Within a reasonably short period of time it will be possible for people in New York or London, or people in the United States and England to converse with each other by radio telephony across the ocean. . . . We know how to build sending machines that will send messages and carry the human voice. We also know how to build receiving apparatus which will receive these waves on the other side. We know how to perform stunts in radio photography and the like, but we don't know much about what happens between the send
