Cold Weather Snaps Antennas Spring Device Overcomes Dif ficulties; Easily Attached. With the first cold snap a good many fans wonder why their anten nas break. The wires were pulled taut and,firm In the summer or fall, and were well secured. The material was of the hest. Everything was made HJjip-shape for the winter. Yet mys teriously, the wire breaks, just when the best broadcasts are coming in. The answer is simp's and suggests a few easy precautions that will pre vent these troublesome breaks. At' antenna that is put up in the v arm weather sir. Inks, as the days ;rnw colder, until the .tension becomes greater than tTie wire v,ill hear—then] if.^ftops. This accounts for many of . the brtaksfu that seem jmtupl.aln ab’.u. Haiti on Antennar. Win>or is also hard on antennas in many other Ways. Vo storms coat the wire with a covering that may v.algu a great many pounds. Wind pulls at the wire. Snow weighs It down. And then comes the trip out on tile cold, icy ro f to mend the broken wire, with rr.in.b fingers, while the listeners are waiting down' below for the niusie that is cut oft. Fortunately, it is easy 1" put tin end to all these troubles. Some fans leave a little slack in tfleir. antennas, but this Is not desirable. A sagging antenna looks badly, but worse iliau this, the swaying in tlm wind varies the capacity of the antenna and pre vents sharp tuning, if you find your tunning is "fuzzy'’ it will pay you to look over jour antenna and take out any slack that may exist. A spring can he inserted In the an tenna, but if it is in tension it is likely to pull beyond the elastic limit and become permanenUy stretched. A spring strong enough to withstand antenna, strains in tension is usually too strong to give the proper flexi bility. Protecting I»evlr#. After considerable experimenting there has been det doped and put on ■the market a, little spring device that overcomes these difficulties and pre lects an exposed antenna from win ter breakage. This tension atabllator uses a spring of strength and length scientifically calculated for the ordi nal^- antenna. As the spring Is always under compression there is no possibility of its being stretched be yond hs elastic limit. No matter how tightly the spring may be squeezed It ■will always return to Its original shape and will always keep its correct strength. The device is attached to the an tenna in a jiffy, without any tools Whatever. It absorbs shocks and strains, keeps an even tension on the antenna, stabilizes tuning and stops all winter antenna breakages and troubles. The device comes in two sizes, a standard model with spring | of correct length and tension for or-1 binary broadcast reception antennas, I end a special shorter model for the, shorter sending station antennas. Protecting Phone < .m<l l ips. Tho extra string tied between tin two main ends of a telephone coni hM a very definite use and Is not. merely s. hangover from l lie cord covering. The cord, attached to the small ring on the jack, takes the •train off the Ups when the phone cord Is suddenly jerked, either acci dentally or purposely. The tips of tha phone cord are not soldered very strongly, and a good tug will separate them from the ends of the cord, which Is not wire at all, but heavy tinsel. The trick is to pull the string through tha ring or hook so that the short tip cords are hanging loosely. All the strain is thus placed on the string, Which can easily bear it. Frinccton Concert.

In*talla4 In your homo complete. Aoriol oxtra. Eaay paymenU A. HOSPE CO. ■ 1513 DougUit St. - Four-Tube Superdyne Is a “DX” Marvel; Engineer Suggests Improvements By BUI X8TEN BRLNN. This receiver will hot give tlie sain? irsulls as an eight-tube superhet erodyne that lias been correctly con structed. but it may give much better results than many so called super het erodynes. Neither will it pick up sig nals that have encircled the globe a few times and deliver them with loud speaker volume, but it will reach out and coax in remote stations with sur prising regularity. It may be said that the receiver is something of a rc necessary for tne construction of the receiver: Two high grade audio frequency transformers. Two low-loss type or other good condensers. .0005 nil'll. max. Two tuning coils as will be do scribed. Four standard tube sockets and four UV-201A tubes, or the like. Two double circuit jacks and one single circuit jack. Two rheostats, 10-ohm. The coils employed in the receiver are of the so-called low-loss type, which may either he made at home or purchased in almost any radio store. If they are purchased care must be exercised to see that they cover the right wave length range with the condenser specified, often the colls are too large to reach the lower wave lengths, 1. e., their inductances are often too high for the range of waves used tn broadcasting. The colls should also have some degree of rigidity or plane of the wooden block. They may extend clear through the block if this is nut too thick, otherwise half inch depth will suffice. When these holes have been drilled, insert wooden •dowels or brass rods of the proper diameter into them, making these ex tend about 2.5 inches above the sur face of the block. When this winding form has been completed, the tuning coils may be wound upon it. Using about No. 20 double cotton covered wire, start by of the first tube. The last 60 turns of this coil constitute the seconda’ry, or th*e tuning coil L-l. Several Types of Ticklers. Tickler coll I,-l may lake one of several forms. It may be wound In the form of a spiderweb coil, it may be a small aolenold wound upon a bakelite tube, or it may be a coil of similar construction to the tuning coil.

This, however, must he taken with the proviso that a modicum uf skill has been used ill the construction of li and also that this is used while tuning in. The circuit is not perfectly selective because it is an actual receiver, not a elaim til an advertisement, but its selectivity has been found satisfactory for all practical purposes. To say that it la very selective ts not an ex uggeratlon at all. for it is able to sup press 1 he wave lengths not desired and yet bring out the one wanted without sacrificing volume, even when the relative separation between the two. that is, between the desired and lhe Interfering wares, is small. "The. post l ye tried of the type,” stater one builder, yvho has tried many of (lie type and many types, and he sup ports his assertion with an enviable list of call letters and distances. Hist itried Praise. No attempt will be made in this article to hand out the old hue of radio humbug about "clear as a. silter bell.” “perfect quality' and 'abso lutely no distortion at. all.” A brll is about as noisy a thing as could he imagined: and those who make the bell comparison are not really Praia ing anything, they are just rattling something loose. They are doing the same thing when they are making the other two statements quoted. The best radio receiver Is far front per fection when It comes to quality in the absolute, but some are mighty good approximations to the tolerable. The receiver described herewith may be made good or bad with re spect to quality Of the signals. So much depends on the luck the builder has In s»lect ing good part* for his audio frequency amplifier. This re r..,-s especially to the audio frequency transformers, and It must he remem Ir-ied tlmt nil that glitters Is not gold, Imt all that is to he exchanged for gold is made to glitter. There are only half a, dozen makes of transformers that are worthy of a place In any audio frequency ampll flier. Try to find a couple of the six. But finding them Is not all of the quality story. They must he connect o.i correctly into the circuit, and then the circuit must be operated with the correct combination of “A, ' ‘ and ”C” batteries. Quality, in so far as it l.s Independ ent of the transmission. Is largely a matter of parts and operation of the audio frequency portion of the re ceiver. One man expressed sur prise that the quality of the signals as dellyered by an eight tube super heterodyne with one stage of audio w;ia so much superior to the quality delivered by a three-tube circuit hav ing two stages of audio. The five extra radio frequency tubes did not introduce any distortion, while the exira audio did. The first stage of audio did not Introduce any distor tion, while the extra audio dirt. The first stage of audio will give x ei y much better quality than the second stage in any circuit. The reason tyro stages of audio are used Is that It Is the least expensive wav of getting loud speaker volume for weak sig nals, Those who are not In posses slon of a super heterodyne purse must not have too delicate ears. Here's What You Need. Before proceeding with the deserip lion let tia enumerate the parts Which Two fixed condensers, one .000" > mfd. and one .001 mfd. One grid leak. 2 to 5 megohms.
