Fliers Talk to Ground From Aloft You Can Listen While Pilots Get Orders and Weather. The flight of regularly scheduled passenger airplanes through the dark of night and the blindness of fog is aided by short-wave radio. The dispatch of these ships of the air is conducted by short-wave radio. The pilots of the ships flying from one area of the country into another where the weather may be vastly different from the region in which they started are constantly being advised by short-wave radio of the exact flying conditions ahead of them. The pilots themselves talk back to the ground stations from which they get orders and advice on flying conditions, and altogether it is a fascinating diversion to sit comfortably in one’s living room following these ships through the night. The new 1935 radios with the allwave features, which you will find on display throughout the city during the radio progress exposition, are the instruments through which you may fly with the mail across the country. How to Get Them This unusual and interesting form of diversion was not possible to the ordinary home before the development of the all-wave sets of today for the standard broadcast receiving set, which is made virtually obsolete by the 1935 models, could not be tuned to either the airplanes in flight or the ground stations which direct them. To intercept their messages which for the most part are in conversation, little code being used, time for them between 50 and 60 meters in the daytime, and between 100 and 130 meters at night. During the twilight hours their messages will be found between 90 and 100 meters. Airplane pilots flying United States mail and passengers are required by law to report their position every twenty minutes. For this reason they have transmitters in their ships as well as receivers. Hear Radio Beam The greater part of their conversation with their control stations has to do with the weather, which, incidentally, is an excellent source of information on weather conditions throughout the country for the radio dialer wiio is interested. Some of the other messages which are transmitted to airplanes have to do with passenger bookings, ordinary dispatching of planes and in some instances the delivery of telegrams to some passenger on the ship. Reservations for airplane passenger space by individuals likewise often are transmitted over the airplane radio from stations to stations and to pilots. Then, of course, there is that interesting directional device, the radio beam, which airplane pilots tune it on their sets when they can’t see the ground over which they are flying or do not care to depend upon their compasses alone. They follow this beam, which is a code signal which grows louder as they come closer to it and fainter as they go off the course. Often one destination will broadcast more than one beam, each having a different code key.' This is true of airports having an exceptionally heavy traffic. How It Works When two ships are approaching the same destination, the ground operator will direct one pilot to take one beam and the other to take a second beam, and thus he safeguards them against possible collision high above the ground. Some murky night before the planes have been ordered down, listen to an airport dispatcher in a couple of ships’* with the use of the beams. You'll find him tense, alert, in constant conversation with the pilots. And woe be unto some other airport dispatcher who tries to “horn in” on the conversation with a bit of gossip while the ticklish business is under way.

Like to Know the Weather? Tune In on Plane Broadcast

Weather conditiqps for almost any part of the country at almost any time of the day or night, are yours for the tuning in, if you have one of the new all-wave radio sets. It’s a mere matter of listening in on the ground-to-airplanes shortwave broadcasts which go on almost constantly in the interest of safe flying. Pilots are kept constantly informed of weather conditions ahead of them as they fly passengers and mail across the country, and they, in turn, inform their ground sta-

Science, Upheld by Money, Lines Up for Profit System Dr. Henry A. Barton Points to Foundations Big Business Made Possible.

B.y Science Service Scientific men line up behind the “profit system” because much of the support of scientific research comes from profitable industries and the endowed foundations that profits have made possible. This is the contention of Dr. Henry A. Barton, writing editorially in the Review of Scientific Instruments, a journal of the American Institute of Physics, just issued. “In the public press, distinguished men of science have recently been quoted in criticism of present political trends as they affect profits,” the writer says. “Whether or not the validity of these criticisms can be assailed on broad social grounds, the factual inspiration for them exists in a serious reduction of the financial prospects of science. It is difficult, that is, to escape the conclusion that scientific research can not for a while expect as much support from profitable industries and endowed foundations as it has had. “Scientific men possessed of a close appreciation of the value of science because of their knowledge of its history are naturally and by no means selfishly concerned. Thus they make efforts to counteract the decline of profits and these may well be supplemented by efforts to gain for science a greater share of what profits remain. The latter would be a step to enhance the direct social value of profits and should meet general approval. “But even if the influence of the whole world of science strongly backed the ‘profit system,’ it is to be feared that present political economic and social trends w’ould not be immediately and perhaps not ultimately influenced very much. What then? It would appear that the only recourse for science in that case is taxes. If the search for knowledge of the physical universe is to go on. the tax yield to scientific institutions must be increased by the same amount as the eventual decrease of the profit yield.” Dr. Barton concludes that colleges and high schools should teach the

tions of conditions over areas over which they happen to be flying. It is required by law that this be done. It is a governmental precaution in the interest of safe aviation. And it is the perfect means for the radio owner who is about to start on a motor trip, for example, to find out whether the sun is shining or there is rain or cold, in the area through which he happens to be traveling. Tune in on aviation broadcast and you’ll find it passing along more weather information than you dreamed was available.

value of science to provide, by influencing political control, “support for science irrespective of future economic developments.” Marvin Specializes in Lonely Singing Johnny Marvin, the man who owns one-thousandth of the Thousand Islands and a singing voice that wins and holds listeners everywhere, will be found daily on WGY in a quarter hour program. Marvin, now under contract in WGY’s artist service, is also giving two programs weekly for the NBCWEAF network, Friday and Saturday at 9:45 a. m. Ordinarily a network feature singer Marvin has been forced to include at least two network programs in response to the tremendous listener demand. Johnny is definitely a personality singer. He doesn’t claim to be a finished musician but unerringly selects the songs which his listeners enjoy most and he puts them over, with the help of his guitar, in a manner that grips his listener. When he sings he sings to you, not to thousands, and in choosing the so-called lonely songs he directs his appeal especially to the shut-ins and the aged. . . The Marvin schedule on WGY follows: Monday. Tuesday, Thursday and Saturday, 10:45 a. m.; Wednesday, 11:45 a. m., and Friday 9:15 a. m. Radio Set Weighs Under Four Pounds Hu l niied Prexs NEW YORK. Oct. 17.—A police radio designed for patrolmen on beat was introduced here recently. S. J. Levy, inventor, demonstrated the receiver for visiting police officials. Worn on a special belt, the six-tube radio receiver complete with the battery belt and loud speaker weighs just under four pounds, or less than the patrolman'.* revolver.

Table Types Present All New Ideas

Popular Sets Built for Convenience. The greatest advance in radio in recent years, the development of the all-wave sets capable of receiving broadcasts from foreign lands as well as standard broadcasts, has been incorporated into the very popular table model types of cabinets as well as in the large console types. This was done in order to comply with the popular demand for a set that can be moved from room to room with ease and also for a set which would be compact enough to put into a room that could not accommodate another piece of floor furniture. , This year’s table sets, many of which will be on display during the city-wide radio exposition, may be had in the standard broadcast models alone, in which are incorporated the improved receptivity and tone qualities, and in the all-wave models as well. The same high standards of decoration which characterize the console models, however, are embodied in the table sets as well.

Police Flash Crime News Through Air

Emergency Calls Are Yours for Listening in on Radio. Radio is credited with having dona more to help police apprehend criminals than almost any one other modern scientific development. And the manner in which it is used by police departments the country over, opens a chapter of romance and adventure for the owner of an all-wave radio set. that will keep him and his family thrilled Police radios, operating on short wave, broadcast orders to patrolmen cruising about in radio-equipped cars. The moment a crime happens, whether it be robbery or murder, or plain disorderly conduct, and police learn about it, the police radio goes into action. 100 to 200 Meter;, The all-wave set owner can listen in as the authorities broadcast their orders and information about the crime. You’ll find police radio broadcasts somewhere between 100 and 200 meters. Practically all of the larger cities in the country now use radio and many of the state constabularies also use them. Their broadcasts are easy to recognize, because they are specifically about some exciting happening. Often while listening to police broadcasts you actually hear the news of the big crime of the day, while it is in the making, and you can visualize more graphically than any written account can bring it to you Your all-wave set dial shows you just how to find them in the air. They run night and day.

Action Described When you have a police station broadcast tuned in you’ll recognize it first by some such phrase is this: “All cruisers, attention." Then follows an order to be on the lookout for some bandits who have just committed a crime, and a brief story of that crime. Many instances have been reported where bandits have been captured almost instantaneous ly through the aid of police radio. A cruiser car may be very close to the scene at the time the broadcast starts. It has but to dash around the corner and meet the bandits. On such occasions the police radios usually broadcast a complete story of what happens. Police radios also are brought into play for the transmission of police information from one city to another. Recently a station in West Virginia asked another station in Ohio to ask a third station in Michigan to locate a man whose wife was dying, and to send him to her bedside immediately. They located hum.
