Such means have been tested and tried out successfully in the Navy, all planes of which are re- quired to carry radio. An added fea- ture of carrying batteries is that illu- mination might be maintained after the engine ceased to function, which is most essential during darkness. The value of radio to aerial mnavi- gation, while perhaps a little slower to be recognized than it was in ma- rine navigation, which pursuit was the first to adopt radio communica- tion, is mnevertheless rapidly being recognized, and both radio and aero- nautical experts in commercial and official circles are indorsing its use. Experiment With Radio. The Department of Commerce aero- nautic branch is rapidly taking over the operation of postal and commer- cial air routes throughout the United States and installing' radio_facilities along them, making possible both communication and radio beacon serv- ice to insure safer mavigation. A re- cent test of radio apparatus on a postal plane for communication use demonstrated that via radio telephony conversations could be maintained for a distance of 150 miles. The plane was flying between New Brunswick, N. J., and Cleveland, Ohio, and the transmitter was located near Belle- fonte, Pa. remotely controlled from the flying field. The special purpose of this transmitter is to furnish weather and other information for fiyers along this route. Another ex- periment was carried out from Had- ley Field, in New Jersey, where the General Electric Co. has recently in- stalled a 1-KW radio beacon. Flight tests indicate that the direction sig- nals from this station are available up to at least 50 miles of the trans- mitter, without the necessity of shield- ing the ignitlon system of the air- plane. Further tests with a naval derfiible are planned. s sort of service transcontinental aerie) " rostes i make it possible for both private and commercial planes to secure weather information, carry on regular radio communication or send emergency messages and also' listen-in to the di- rectional or guiding radio beacons all on the same radio receiving set. Prac- tically all radio work of the depart- ment is now handled by the light- houee service, which also handles the airway illumination system. The Gen- eral Electric Co. has just produced a small and compact aerial radio re- ceiving set weighing but eight pounds, which is being tested out on the com- mercial routes from Boston to New York and by Army, naval and air mail experts. Radio Beacon Service. A recent conference of experts of the International Radiotelegraph’ Con- ference discussed the radio beacon service and the need for a band of frequencies rather than a single chan- nel, as well as use of the 600-meter international distress or SOS chan- nel in aerial navigation as well as in marine for emergency uses. Activities and developments in the several governmental bureaus and de- partments concerned with radio and aviation all indicate a closer and closer affiliation of radio and aero- - nautics, following the similar but now old relationship of these two sciences —communication and navigation—at sea. tios | e LIGHT AFFECTS WAVES. Reception Is Reduced by Day and Clocks Err. ! Wheon using a set in sections of the country where daylight saving is in force, bear in mind the effect of sun- light upon the Hertzian waves. It is extremely detrimental, to say the least. Even in sections where daylight saving i$ not the rule, the days are considerably longer and sunlight ex- tends over into that period of radio program work which in the Winter is unencumbered by the sun's ray It may be 8 o’clock standard time or 8 o'clock by daylight-saving time, but it may not necessarily be 8 o'clock by radio time. The chances are it is more likely to be 6 o'clock, or, as compared with the dead of Winter, when days are short, 4 o'clock. Sunlight will kill about 70 per cent of the energy of radio waves. Remember this when tuning in at too early a radio hour for the sort of programs which one could get with much better results in the Winter. —_— ALUMINUM AUTOS MADE.

There are certain peculiarities about radio that makes this especially true. You know, when a man has trouble | getting from omne place to another in hi is car he doesn’t blame the weather unless he finds that the o voad are in a similar fix. knows there is something wrong with the car and es steps to have the trouble remedied. With his radio he reasons aloug different lines. When nothing comes in through the re- ceiver, ov just a few jumbled and dis torted tunes, he jumps to the conclu- sion that he's run into a poor night of radio and promptly switches off the | set. Now the the chances are 10 to 1 that is something wrong with h veceiver. It has become a habit with | him to blame the ether for every-| thing that goes wrong. so it come natural to him to overlook the possi- | bility of trouble with the set itself. If the outfit fails to produce results | the next evening he probably con that reception still is poor. | Thus, if there is anything vadically wrong with the set, such as the | battery in need of water or a shor in the wiring, the trouble isn't ually will grow wor Regular service would obviate all this. Many radio owners are cheating evenings of good entertainment just bec: they do not have a check on their equip- ment. And. besides, they pay for the extra trouble which neg ways entails, OFFERED IN SUMMER! Outside Interests Held Likely to Make Radioist Forget Quality | of Air Entertainment. Tennis racquets, golf clubs ming suits and new automobiles a way of making the radioist forget what the Summer has to offer him by wayv of ethereal entertainment. Nevertheless, programs are continu- ing to be first-class and varied, with many important features scattered throughout any typical week. Though Summer is considered to be the low- ebb period in radio, it is interesting to mote that a recent week offered the radioist the following outstanding features: First, a concert by a tenor of the Metropolitan Opera ‘Co. over 12 sta- tions. This was followed on Monday by a prominent entertainer and his group of artists over 14 stations, and later by one of the most famous out- door bands in the country. Still later “Rigoletto” was given over 12 stations. Tuesday brought a concert over 19 stations by an orchestra of interna- tional reputation, while on Wednesday listeners heard two other orchestras of nearly equal prominence sent out over 12 and 10 stations, respectively. Thursday programmed an operetta over 14 stations, and a_short while later the New York Philharmonic Orchestra went out over 9 stations. On Saturday there were other out- standing features, including a famous band.. Such a week of radio enter- tainment, figuratively, and perhaps literally, would have had front-page mention but a few. years ago. To- day such enjoyment has become per- haps a bit too commonplace, em.

Out What Remains of the Summer Furniture properly Operating Device to Start Set. With “B" eliminators so widely used, it is surprising how carelessly they are operated Ly the average set owner. There are right and wrong ways of starting a set equipped with an eliminator, as well as speclal cau tions required in switching it off. ! Always plug in the set 50 as to light the filaments before switching on the B eliminator. The purpose of this is to save the set from the damage of an “open circuit voltage,” which 1s created when “B" voltage is applied while the filament circuit is not cper- ating. The damrage is directed chiefly against the transformers. If this rule applies in starting the set, maturally it applies equally well | in shutting it off except for the re- versal of the process. Switch off the eliminator and then pull out the piusg that controls the filament circuit. Many set owners get along without any apparent trouble by ignoring this rule. Only excellent transformers pre- vent trouble, or sometimes it merely is a matter of luck. It's a risk no radioist need take. ELECTRIC BILL FACTOR. Increase. Charged to Radio, May Belong Elsewhere.
