Apropos David Sarnofl’s observa- tions that the future of the radio art holds miore in store than past, it is perhaps well to review some of the “‘peaks in the waves of wireless prog- Tess” as set forth In the new edition of the Radlo Bervice Builetin of the Department of Commerce. Its chronology of radio events dur. ing the last century contains no more significant year of accomplishment than 1926.

[ALTER RADIO PROGRAMS SO AS NOT TO INTERFERE | Stations Co-operate to Avoid De- tracting Fans from Features of One Another. “Radlo stations are beginning to | defer to one another. True, they have | done so before in matter of lending | time to sister stations for some spe- | clal broadcast where both share a wave length, but now.ye find them altering their programs d com- | petitfon with some particularly good feature offered by a rival station,” says the February Radio Broadcast Magazine editorially. “Thus it was that WRNY shifted its New York Edison Hour back 30 | minutes to avoid overlapping Eveready Hour of WEAF. And W.J back in the foot ball season, canceled its Broadcast of the popular Yale Princeton game upon learning that the WEAF was to do the job, and made | last'minute arrangements to broad- cast the Army-Notre Dame game Instead. Other instances have occurred “This problem of duplication is not & very serious one at present, for there aren't so many not-to-be-missed features that they cannot all manage to fit themselves nicely into the week without treading on' one another’s | toes.

Thete is still a vast audience not wholly informed . . . . asking what radio has really accomplished. Particularly with regard to the much heralded “lighting socket radio,” there is a demand for more information. People want to know . . . . Is it safe to buy now? Shall we discard our old sets now . . . . or wait? And which sets have passcd out of the experimental stage? A thorough comparative research has produced the answers The answers cannot easily be gleaned from the mass of advertising that assails the radio buyertoday . . . . claims scund alike on paper. But they have been ex- haustivelystudied ina laboratory where every important development of radio, of all makes and sorts, has been tested and weighed and valued. And it 1s on the basis of this comparative research that the Radio Corporation of America has been em- phasizing as the greatest achievement of modern radio receprion—the Radiola 28, eight tube super-heterodyne. And as the greatest achievement in musical reproduction —the RCA Loudspeaker 104. The simple statement of facts which follows will show not only where successful “lighting socket radio” stands today, but why the same performance cannot be expected of the ordinary radio set. It will explain, t00, why a hundred thousand people who have b:;z these instruments would have nothing else, of prie. *“Lighting socket radio” that is not mere “battery elimination” RCA Loudspeaker 104 RCA Loudspeaker 104 was the first to introduce realism in radio reception. It was revolutionary when introduced—and it is sull revolutionary. One of the secrets of its success lies in the discovery of anew basicacoustical principle—and in the use of su- per-power amplifying tubes and power drive from the lighting socket. ‘The power apparatus necessary for the actuation of this loudspeaker also contains all of the basic elements of the battety eliminator. Thus, when connected to Radiola 28, through the medium of an A.C. Package, the power unit in the RCA Loudspeaker 104 eliminates all batteries and provides operation direct from the lighting socket. Whean the Loudspeaker 104 is operated in connection with sets other than Radiolss, the power unit in the speaker supplies “B" battery voltage: that is, it mkes the place of “B” batteries. The Loudspeaker 104 was not designed for reproduc- tion in large halls and assembly rooms. It was iatended for use in apartments and homes. While capable of great volume, it may be operated at any volume: but it should be borne in mind that one of the chief factors contributing to its realism of re- production is theamount of power employed to actuate the instrument. Yet it is decidedly economial in operation. Adopted by the leading phonograph companies It was the first to catch the notes of the entire musical scale, reproducing so faithfully that the great phono- graph companies employ it for phonograph reproduc- tion as well. Remember, RCA Loudspeaker 104 is not just 2 loud- speaker. It is a loudspeaker plus a power amplifier, plus rectifying apparatus for the elimination of bat- teries. Batteries would not provide sufficient energy to operate the Loudspeaker 104 satisfactorily. The power required must be drawn from the lighting socket. And its purpose is not mere volyme, but a remarkable quality of musical reproduction. Combining the finest radio reception with the finest musical reproduction Radiola 28 The term “'super-heterodyne™ has carried an atmos- phere of magic for the past ten yéars. In its original form it was a complex laboratory device, not suited for manipulation and use on the part of thosejnot technically trained. RCA engineers took this complicated device, simpli- fied itand produced one of the most efficient broadcast receivers known to radio. The popularity of the super-heterodyne comes from the following features: First, its great sensitivity. It is so sensitive that radio broadcast reception can be obtained from great dis- tances without any aerial or outdoor wire. A coil wire, called a loop, takes the place of the aerial: or the loop may be replaced by & short length of indoor wire. Thus, the super-heterodyne is particulatly suitable for use in apartment houses where the erection of aerials is impracticable. In the matter of selectivity, the stands supreme. Its abilicy to receive from one station to the exclusion of all others is oo other type of receiver. The ability to do this comes from a novel feature of the super-heterodyne circuit To simplify operation, the super-heterodyne is now provided with uni-control runing mechanism. With the movement of one control, station after station is brought in. Another exclusive feature of the super-heterodyne is its sealed-in construction. Lifc the loop and cover, and note the business-like, clean-cut sppearance of the internal mechanism. It reminds you of a multi- cylinder automobile. This sealed-in construction, known as a “catacomb,” isa com; protection mmemwdehmemkqmmnflm moisture and dust. And to assure the finest possible clarity of voice and music, this Radiola is matched to the grest broad- asting stions. Its transformers, tubes and all points of design that affect tone quality are the product of the same engineers who designed the ‘brosdcasting apparatus. The product of the combined research of RCA, General Electric, and Westinghouse Radiola 28 and RCA Loudspesker 104 are also syn- chronized to one snother—engineered from begin- ning to end in the same laboratories and by the same engineers. With this combination, you have the supreme achievement of radio today. * » > From all these facts, it can easily be seen thar the finest “lighting socket fadio” today is something more than a radio set with battery eliminators. The perfecting of its basic principles of electtical te- production was an important forward step both for radio and for the phonograph. Hasit passed out of the experimental stage > Decidedly, yes—in the Radiola 28 and RCA Loudspeaker 104, for they were far ahead of their time and they have had 2 long and strenuous “road test.” More convincing than words or facts—more impres- sive than a thousand testimonials—is the judgment of your own ears.
