30 EXPERT PREDICTS - FUTURE OF RADIO Naval Research Director Sees Stabilization of Ap- paratus Coming. everal of Uncle Sam's radio ex- perts and administrators have been persuaded to predict some of the de- rlopments likely to greet us during he new vear, although some of them explain that it fs a very \Hu’l‘nfllnl business to make any predictions con- | cerning radio development. They say the radio art {8 so young in compari son with electrical engineering which it may be called an offshoot, that things take place so rapldly as to render most predictions little bet- ter than mere specula ns.

York York Boston Omaha WASHINGTON ]szzs IMPROVED PLAN ‘ IN DIRECTING WAVES Dr. J. H. Dellinger Suggests De- velopment in Radio Concentrated Beams Is Possible. During 1925 Dr. J. IL Dellinger, director of radlo laboratory,' Bureau of Standards, believes the develop- ment of a practical means of direct- Ing waves In concentrated beams ni desired directions should be accom- plished, including the use of this sy tem at lower frequencies than hereto- fore. This system should also be adapted to the reduction of Interfer- ence. Introducing another element of in- terference reduction, he anticipates improvements in direction finders| and the development of very direc- tional receiving systems. He also! predicts the utilization of radio waves of between 150 and 15 meters on & regular engineering basis, gether with an increased knowledge of the possibilities of these waves and the mode of their propagation. Utilizing the higher frequencies, the perfection of means for relaying and rebroadcasting may be nticl- pated in 1925 and adapted to various services. Broadcasting will no doubt take on & more definite form as a distinct service rather than its origi- nal phases of novelty and pastime, he believes, anticipating higher quality in receiving sets and higher power in broadcasting stations. In- terconnectlion and high power will give greater availability to programs than in the past Touching on the development in receiving setx, Dr. Dellinger believes {that a wider use of highly selective sets can be expected next year and that progress will be made on devices {for using alternating current as a tube supply, although batteries give hard to dis- ;.

CHICAGO, TI1., January 3.—With the arrival of Winter storms throughout the Northern states, rallroads are de- pending more and more on radlo to ald them In dispatching train service When communication by ordinary methods becomes impossible. When all other means fail, radio is practi- cally certain of getting through to the desired points with a minimum amount of delay. Amateur radio scored again re- cently, when G. W. Bergman, owner and operator of station 9CA, at Dwight, 1L, handled Important mes- sages for the Chicago and Alton Rail- roud. Due to the heeavy snow, the railroad telegraph lines were inopera- tive, so Bergman was asked to es- tablish communication between Dwight and Chicago. Statlon 5CA got “on the air’ immediately, but was unable to “raise” any Chicago sta- tlons. He managed finally to relay some messages through 9AZN, the station of A. D. Sanfal, in La Crosse, Wit By this means, Bergman got inte communication with R. H. (e Mathews, central division manager of th American Radio Relay League, who warned local amateurs to listen for Bergman's signals. He also asked the Chicago broadcast stations WEBH, WG nd KYW to have their listeners notify amateurs to get in touch with SCA In a short time. 8CA “raised” 5AAW and 9BE, the stations of W, E Schweitzer and M. H. Romberg, bott of Chicago, and the traffic for the Chicago and Alton was then handled | direct from Dwight to Chicago b means of amateur radio telegrapl attery Charges 6 volt “A” store age batteries.

Balkite Radio Power Units furnish constant uniform voltage to both“A" and “B” circuits, and give your set greater clarity, power and range. The Balkite Battery Charger keeps your “A" storage bat- tery charged. Balkite “B” replaces “B” bat- teries entirely and supplies plate current from the electric lighting circuit. Both are based on the same principle and are entirely good service and are place.

I think this will be solved by the use of the Plezo electrical ef- fact of quariz crystals. This station already has a set controlled by a crystal, using a 20-kilowatt tube. This would be an ideal system for broadcast sta- tions, since the crystal, which always absolutely determines the wave length of the station, can be ground | to fust the right dimensions to cor- | respond to the allotted wave length of that statian. There is no possibil- | ity of that station drifting off tune, T expect, therefore, to see a marked | increase in :he use of quart crystal control for steadying frequencles.” partment of Commerce predicts for 1925 really useful radio reception through the elimination of static and other interference. Development of interconnection, together with some general rise in the power level of stations, he helieves, will be the me- diums for improving broadcast recep- tion, “In radio development during the past year,” said Mr. Davis, “two fac- tors are outstanding—the use of short waves and wire interconnection of stations. Both are of great im- portance. The short wave has found its place in commercial and amateur transoceanic communication and in transmission for rebroadcasting both 2t the home and to places across the seas. In domestic use it is & rival of wire interconnection, both being & means to some end—the furnishing of simultaneous programs to several sta- tions. “1 consider interconnection, in whichever mode effected, almost es- sentlal to the future of broadcasting, it we are to ook at radlo as a means of service to all our people all the time. It ultimately means national programs, natlon-wide utterances, more valuable subject matter and that great happenings in which our people have so vital an interest will be made aveailable to everybody.
