Program of publicity for the west- ern region served by the Burling- ton system was launched Friday night and will be continued on the first and third Friday of every month on “Burlington” nights at WOAW station, Omaha. The pro- gram will continue until February 1 or possibly later, according to information received by J. A. Leary of Casper, district freight and pas- senger agent. Dr. G. E. Condra, director of the conservation and survey department of the University of Nebraska will personally conduct his invisible nudience over the Burlington with trips of 10-minute periods and two yeriods a night, until radio fans ave been carried over the wes! territory.

Because winter storms mean heavy etrains on aerial and ground installations, now is the time to make a thorough inspection of the outdos wiring system. See if the guy-wires holling the aerial masts and the aerial wires in place are all taut and tight.

Be- tween the primary and the. ordi- ary sécondary coils of @ set this transfer of energy through the air is essential in most receivers, but not so in the Filter Tuner. When energy is passed directly from the primary to the secondary coils by induction, other pulses of energy as well as that from the sta- tion desired are received. This makes for interference and sharp t ning is difficult. If the coll of a filter circuit is used to effect this transfer of energy, however, it can be split into two parts so that there is no direct transfer of energy to the secondary by induction. Transfer by induction can take Place between two coils only when they are parallel to each other. ‘When two coils are turned at right angles to each other they ere at Use Proper Socket When using special tubes which require special sockets it is best rather difficult to handle.

BETTER PARTS DEMANDED BY BUILDERS Coil designers are departing from the tube wound type of inductance by using a self-supporting form of winding with-an air core. Another type that has just appeared on the market has the tube cut away leav- ing only a lattice to hold the coil in position, while another uses a corrugated form. These improve ments in coil construction are a healthy indication, and show that the manufacturers are recognizing the change that has come about in fandom through the educating in- fluences of the radio editors. Heretofore, the majority of the radio public were without the technical knowledge that would en- able them to buy intelligently, and were compelled to accept the state- ments of advertise: t their face value, No inference is made here that the advertisers were not stat- ing the truth, but the ignorance of the average radio buyer was a temptation for exaggerated claims that seemed difficult to resist ip many ceses. This new-found knowledge of the fans is a gilt-edged security against further attempts at exploitation, and is certain to be reflected in a more stable condition of the indus- try as a whole. The new condition gives to the :qualified manufactur: ers a long sought opportunity, and to the others a hint to secure com- petent technical advice. It gives to the fans a joyful confidence that at last they are in a position to judge for themselves. them The field of induction about a coil is be- form indicated by the arrows. on the fields of the two coils oppose each other and no induction takes The Air Slogans WLAK—Bellows Falls, Vt—“The Maple Sugor State.” WLAX—Greencastle, Ind. “The Greencastle Community Station.” WLW—Cincinnatl, O. “The Sta- tion With a Soul.” WMAF—Dartmouth, Mass. “The Voice frpm Way.

Vernier Rheostat Is Best for Detector For detector filament control a rheostat with a vernier adjustment is advisable. The temperature of the filament determines the fine variation will bring the tube to an operating point of greatest efficiency. In some circuits, re generation is controlled by the fila-_¢ ment rheostat, and a wire rheo* at offers too coarse an adjust: ment. The rheostats using cafbon com- position packs as a resistance are capable of giving fine variations, but many of these are so construct- ed that when the carbon becomes hot it sticks and changes its re sistance with the amount of heat. | This type of rheostat should not be operated, therefore, above the specified current rate. Set Improves Health. A radio prescription 1s putting 8. R. Helms, of Monroe, N. C., back on his feet after an Invalidism ot over fourteen months. Writing to WGY recently, he said: “I am one patient that an M. D. prescribed a radio outfit for,.and it was the greatest prescription he ever made, as it has done me more good than specialists and sanatoriums. I sin- cerely wish that every shut-in could. have a radio set.” Best Hour Is Eleven, At this time of year the best time for receiving distant stations is from about eleven o'clock in the evening until two or three in the morning. A marked change # the intensity of pulses from distant sta- tions can be noticed about eleven o'clock, Two Batteries Needed All but the cheapest kind of radio sets must be used with two bat- teries, supplying two different vol tages, One battery is used to light the tubes, the other furnisnes a higher voltage to actuate the phones or loud aker. The first is called the “A” battery and the second is “B” battery. How to Use Vernier. » Use a vernifer control where tun ing is so sharp that it is difficult with ordinary dials. A vernier will enable you to move the dials slowly and adjust the set to its finest balance.
