CShetdy These types of vernier condenser will aid in fine tuning and help to get the most from a FllierfTuner. There are plenty of good ones now available. Choose the best one you can ailord. to Plate New Filter Tuner Wofk Best with Verniers Set Which Has Very Unusual Ability to Separate Stations ;Needs Accurate Control. v By PAUL McGINNIS , A Filter Tuner, If It Is to be tuned well, must b equlpjxd with two , good Tenfier condensers. The vernier moves the condenser slowly, bo ; that the dial can he turned to the proper point. As mnay as three sta- . tlons hate been received and completely separated with a turn ot a half iegree on the tuning dials, and such fine tuning is difficult without some kind ot vernier. . There are in general five different types of Termer, all of which - have merit. In the illustration above, the first consist of three gears, This type puts the Ternier knob "in low gear." so that a complete turn of the vernier will move the dial only a few; degrees. One advantage ' cf this type is that the vernier is always ready to be moved one way or the other, and; the slight play in the gears does not interfere with Cine worlc . The condenser itself Is a problem of Importance. If it Is not built properly It will allow energy to leak i-way, and will be inefficient in bringing in distant stations. In general, each set ot plates should be well insulated, preferably with bakellte, from each other and from all neighboring conductors. . A yearago it was difficult to find condensers which employed a "pigtail," or flexible connection, for the movable plates. Without such connection, the friction bearing must provide contact, and It is Inefficient when worn or dusty. . MAKE SPECIAL DIALS. . Dials are made to give a vernier action on any condenser. Such a " dial is shown in the second Illustration. It will enable you to use . ordinary condensers - which .you may have on hand. You - can - use condensers ; without any kind of vernier, but it takes an unusually steady hand to get the tnost out of such a sharp receiver without some xaechanical aid. The third picture illustrates the lever type of vernier. This gives an excellent control, but in some types the lever should be returned to a neutral position for each new station. If the lever is swung far to the right for instance, when you tune In a new station you may wish to awing the lever Just a little far ther to the right, which would then be Impossible, and you would have to make another adjustment. ' THE CHEAPEST KIND. The fourth illustration shows the least expensive type of vernier. A small rubber wheel is placed so that It will make contact with any dial. By turning the wheel a good adjustment can be obtained at all times. The fifth picture Illustrates the tingle-plate type, which Is sometimes called an electrical vernier to distinguish it from the other types, which r are 'mechanical.? It must be made well if it is not to Grid Leak Will Not Control Filter - CERTAIN "unscrupulous dealers are selling variable grid leaks to take the place of the high resistance used In the Filter Tuner.. 'One reader reports that he saw more than fifty customers purchase such units, which' are worthless In the circuit. The resistance called for In the Filter Tuner circuit' Is about 10,000 ohms, and some of the units which are marked 10,000 to. 100,000 units work well. A variable grid leak Is made to provide a resistance of about 600,000 to something over 2,000,000 ohms, and Is utterly useless for-controlling resistance In the Filter Tuner. - New. units are now appearing on the market which are variable between 6,000 and 25,000, which will give excellent results. . . S!l U ri -''- '.r r,:i' V.' How Impr ove Circuit cause losses In the set, and it has the disadvantage of some of the level types in that It may be giving its maximum amount of capacity when, just - a little more is needed, in which; case a new.; adjustment of tho dial must be made. Radio Step Is Latest Dance Innovation Raymond Bott, of Youngstown, Ohio, after delivering an address at the recent convention ot the American Association of Masters of Dancing in Chicago, introduced "the Radio." It's named that because the dancers follow an imaginary sigzag line down the floor, like the lines of electricity depicted by artists. The movement suggests the old grapevine step which was used be fore the war. Anctner reason wny it is called "the Radio" is because it can be done nicely on about six square feet of floor space so it is uractlcal and pleasing In a small house to radio musict . Stage Door Johnnies Now Radio Romeos -Radio Johnnies do not wait at stage doors "with smiles and bouauets. but they do slip away quietly in the moonlight and drop love missives Into tha nearest mail box addressed to their favorite radio actresses. Then some of them wait and wait until Rose Brown, charming dramatic star with the KGO players, can simply find time to answer and say how nice it was of them to write her. "My radio -friends win nave to be Datient Miss Brown said the Other day. "They have overwhelmed me with letters.". 1 " . "Your voice is marvelous,"- tnisw from a Radio Johnny who Is also a miner in Ariama, : Miss Brown's work as "Judy" in the' drama "Daddy-Long-Legs," broadcast from KGO recently, drew forth a deluge of letters. Among them was this: "Dear Judy, please kiss your 'Daddy-Long-Legs' again some time, if it isn't asaing too much. Your voice is the sweetest I have ever heard over radio." Aonarentlv life at sea is more enjoyable when the KGO players, with Rose Brown in the cast, come on the air. Here is what a Radio Johnny, who is a mate on a tramp steamer, has to say,- ''Jumping sword fish!- Half the crew are in love with your little leading lady, Ros Brown Including myself." "We are all head over heels In lova with the sweet voice of Rose Brown," writes a bashful radio operator on the S. 6. Newton, addressing his letter to Station KGO. "The boys are still talking about her." . . " The Weagant system .of' obtaining regenera- iicn by tuning the plate circuit is efficient - be- cause the-" tickler" coil is always in the same , position. ' - ' Tube Must Have Prop er Voltage for Filament ; A-filament of a vacuum tube is heated to a temperature hira enough to emit a stream of electrons which flows to the plate of the tube. The filament has & current rating specified by the manufacturer. In the" case, of the WD-12 and 201-A. tubes, this current rating is one-otiarter of an ampere. To force one-quarter of an ampere through th resistance of the filament requires a potential or voltage of five volts across the filament tsrminals. If more Voltaee is ADnliPd. thn fiinmof will burn out, unless another resistance is included, such as a rheostat. u oci.cn .i. m m i-u uunu ui iiujtL me current now. to tua amount speciuea That memories of days gone bj are awakened in the minds of gray haired. Radio Johnnies s indicated by this letter, addressed to KGO: "When Rose Brown speaks It makes me think of old times gone forever. Have you one of her pic-, tures? I wonder if her picture is as charming as her voice." .' "I'd rather be a radio actres? than anything 1 know," said the de mure little lady to whom every mail brings so much evidence of admiration. "Radio Johnnies are so sincere: they are just e very-day folks like you and I. you see." Old Cells Have Use Dry cells that have done duty as filament current supply can be used as "C" batteries. The power required for this work is so small that tnese otherwise useless dry cells can be used successfully. The filament voltage la supplied by one battery and the plate voltage by another. The first is called the "A" battery and the second the "B" battery. In the first the voltage is usually six, if it is the storage type, but if dry-cell tubes are used lower voltages are employed. -For the - plate circuit a much higher voltage Is required to set up a strong electronic bildge across the space between the filament and plate, and to send a current strong enoueh to energize the circuit. For the detector a battery ot 22 volta is usually employed, although some tubes have a better detector action on a higher plate voltage,- The amplifiers work on 1 still higher voltages, beginning at forty-five and going as high aa one hundred and thirty-five The voltage may be Increased between circuits without adding more battery. In the case ot audiofrequency transformers, the secondary terminals have a. greater poten tial, or voltage, difference than the primary, because of the greater number of turns of wire on thei secondary.. If the primary has one thousand turns and the secondary five thousand, the transformer is said to hate a sten-un ratio of five to one, or a voltage increase ot five to ine. it means mat a cnangiu? current In the primary at twenty volts' pressure will produce a changing current in the secondary at one hundred volts. It is for this reason that amplifying transformers amplify the signal. - If the ratio ot the transformers is too high, the vacuum tubes will he shocked into an inoperative state because of the excessive voltage. This condition of Improper ume. " The only way to correct tha trouble is by lowering the Potential difference across the terminals of the secondary of one or both trans formers. This can be done by d creasmg -the "B" battery Voltage, or by replacing-: the transformer with one of lower step-up ratio, or by shunting the secondary with a variable resistance, which will decrease the potential differ ence. How They Learned ueiore me advent or vacuum tubes, many devices were tried to improve the sensitivity f the crys tal and other similar - detectors, About twenty years ago. Professor It. A. Fessenden, experimenting on this problem at his station at Brant Rock, Massachusetts, discovered the. heterodyne system. Using an aro to generate hlgh-freQiencey oscillations, Fessenden succeeded In lowering the resistance of the aerial ana tuning circuits by coup ling the locally generated wave to the incoming one, which had the effect Of boosting the Incoming sig nal. sharpening the tuning and in creasing the sensitivity of the de tector. The present system of heterodu ing Is practically the same as that developed by Fessenden, the only difference being in the source of current, which is now produced by the vacuum tube oscillator instead ot the arc. i All regenerative circuits, as well as the super-heterodyne, make use IMPORTANT BECAUSE IT INCREASES. .' ORIGINAL CURRENT RECEIVED 1 ".The plate circuit of the detector tube Is the source of tbV local cur rent that Increases the volnme of the original signal received froartha secondary through the aerial and primary circuit. In tlmpla fdmv without auxiliary circuits for producing regeneration, the plate circuit consists of the "B" battery, telephone receivers, plate and filament.? While some tubes produce thei battery Its proper place it tha jow. potential end ot the circuit, wit! the trsnsformer or telephones Between the two. - . -. With the exception or u Weagant circuit, or modifications of It. where the plate coil is artfanJ. the plate circuit throufh a condta ser, a fixed condenser, .cqj micro farads capacity should be aauntea across the telephones or trans former - primary. This condenser provides a bypass for me rasio frequency current that would ha choked back otherwise by the coil windings of the telephones or trans former. . - - - - POSITION OF TICKLER. . la . the . case ot the . ordinary solenoid or tube -wound coll' the tickler should be next to the "low potential, or filament end. Nd'di. ference in regeneration occurs.' but the freedom ot the grid end ot the secondary from absorb tloa itlteta increases the efficiency. 1 - In a variometer tuned plate cir cult there ara advantages cot- obtained In the tickler system. 'The plate circuit can be brought lata resonance with the secondary ty tuning, which maies It more Selective. A combined tickler and-va riometer effect can be had by-1 ing a third coll, of about five tons, in close Inductive relation to thai secondary, as an ordinary tickler and connected m series wlth;th, variometer. This arrangement ha the advantage ot each system, pro ducing great volume ot regesra tion and a more selective circuit. It the set is built along the Uses suggested, with low loss aerial, pri mary and secondary. It will -pro ducevolume with selectivity, bct& for local stations and distant ones. best detector action at high volt ages, it will be found that the average run ot tubes detects best at voltages not exceeding twenty-two and one-half. Where a higher vo'.i- aga is used, louder signals may bo produced, but they will not have te same quality. The operatoi should work? rather toward tho other extreme, reducing the de tector voltage to a minimum value, even twelve volts tot being too low in many cases. Filament temperatures nave a great Influence on the behavior of the plate, current. This current passes over a bridge ot electrons made by the. bombardment from the filament and, unless the rheo stat is adjusted to a correct value, either too much or too little cur rent will pass through the plate Cir cuit. A point on the rheostat wiu be found beyond which no increase in signal strength will occur. HOW TO ADJUST RHEOSTAT. This point of filament adjust jneut should be found with the re generative control at tero, for It can -be determined only when the tube Is used aa a simple detector, Of the two systems for producing regeneration, tickler and vario meter, the former is preferable be cause It produces a stronger feed back action. This accounts In part for the success "and popularity of the One Knob, honeycomb, and other tickler feed-back-circuits In connecting a regenerative coll in the plate circuit, one terminal, of it must go to the plate, and the other to the telephones or trans former, binding post, with the B battery at the base of the circuit. This arrangement is best because it gives the coil its. proper place at the high . potential end, and the ; 3 j t i Soldering Is Easy If Cleanliness Is Made the Watchword ' i of this system. - It is tho basic prin ratio in amplifying circuits la indi- ciple behind the present system ot cated by. distortion and great voi- i u.wuv-- The chref essential in doing a good Job of soldering is first to get' the surfaces perfectly clean; ' The touch of a finger, may coat, them with oil sufficient to prerent th solder from taking a firm hold.

Flux is a Latin word which means flow, and tbe soldering flux is the medium that causes the anlder to flow smoothly over th narts.

For solder in itself is not strong, and It is only that thin layer which actually ilea between the parte ana with them forms an amalgamation, that binds them together.
