By PETER MOMBELLO Tube amplilieation, with its persist' Ing noises, has been Mie onfy thing to prevent a radio set from comparing very favorably with n phonograph for clear musie. 'Also, because of these fiolsos. many, indlo fans who are satis fied with the locals have gone hack to the crystal sets to enjoy clear, mitti- ral and faithful reproduction. These pi#*perties of the crystal ac-ount for Its existence In this age of multitube seis. If tlie crystal can he used as a detector, why cannot it bo used as an amplifier (if this term Is appropriate)? As a matter of fact, i( can he used in the latter way, and the'ivst of this article will he devoU'd tn the construc tion of a two-stage amplifier using crystals. The following parts will he needed: Two audio-frequency transformers— one of 10 to 1 ratio and another of C to 1 ratio; two perfectly insulated crystal detector units, two very sensi tive galena crystals, two mica fixed condensers, .00] mfd. capacity; one “B” battery, 22*4 volts; six binding posts and one nidlon panel, 7 by a. All these parts are to he very efficient, and, considering the fact that they can he used over and over again. It is worth while to spend a little more and get good ones the first time. Must Follow Directions. The diagram given with this article must he followed very carefully. Of special importance is the connection after the first amplifying crystal. The wire..that comes from the secondary of the first transformer and goes through the crystal is to he connected to the secondary of the second trans former. If this connection should go to the primary the amplifier would not work, and the sensitivity of the first crystal would he ruined by the bat tery. No baseboard Is to be used. The transformers should he mounted at right angles to each other on the In- a side of the panel. The first crystal should he placed above the first transformer, and the second crystal above the second transformer on the front of, the, panek The connections to both of them should he reversed to give the best volume. The input posts should he on the left and the battery posts and output posts should he on the right. In wiring, use pure soft drawn cop per wire or gohhplated wire. Under no circumstances should you use the tinned bus-bar wire, ns Its surface con ductivity Is very low. Make all con nections direct in straight lines and solder absolutely every connection. When soldering the connections to t^ie crystal detector units make sure that you remove the crystals, as they will he njined by the heat or decomposed by the soldering flux. For the sake of tone quality use fixed condensers hav ing a mica dielectric, and connect these directly on the posts of the transformer as shown in the diagram. Since different transformers vary greatly In their construction, it would he worth while to experiment with the capacity of the two fixed condensers. Although a "B” battery of 22*4 volts is used to force the signals tluarngh- the amplifying transformers, the unit should he built with the greatest of care, as every hit of energy is to be preserved if the amplification is to he successful. Operating Amplifier. In operating this amplifier connect the phone terminals of the set to the primary of the first transformer; then carefully manipulate the first crystal until the greatest volume is obtained. Follow this by manipulating the sec ond crystal for louder results. After a little parctice the two crystals can be worked simultaneously. This amplifier, although It cannot compare with the regular two-stage amplifier using tubes, will he free from the tube noises of the latter amplifier. Under good conditions, a crystal set will do very good work with this unit, and the locals will come in as strong as on the ordinary two-tuhe regenera tive receiver. Although the range of the receiver will not he increased by adding this amplifier, the signals w hich were not audible will he greatly amplified and they will he heard clear ly in the phones without the usual straining of one's ears. If, due to the location of the re ceiver, one of these units fails to <q>- erate a loud speaker, two of^ltem should he constructed. The second amplifier should use one medium ratio transformer and one low ratio transformer. It should he connected in the same way as the first unit, and should he placed after the first unit, with Its Input posts connected to the output posts of the first amplifier. This combination will work very well in any case, and tor the quiet ' satisfaction these amplifiers give they are well worth the trouble of construction.— New York Herald-Tribune. > Where Trouble Comes in Altering Your S. C. Set The trouble in altering the single circuit set lies in getting the tithe to oscillate at the high waves, and also In the loss of volume and distance reception whet^dry cell tithes are used. In trying to overcome these two things the ultra audlon circuit has been sug gested at different times, hut this cir cuit ^n Tfs standard form also has shortcomings, making it little better, if any, than the tuned plate circuity The receiver described herein is an Improved ultra atidinn circuit that fills values and also try shifting It from Its present position to one wherern it is connected from the grid to the neg ittlve or positive filament.—New York Sun. Plan to Test Radiation Will Prove Worth While do not radiate. _ Jn s< claims seem to Uave Secondary Circuit Connected in Ultra Audion Manner. the hill hotfT In ease o~f oscillation and in distance of reception. A glance at the circuit will show to the fan* that it is a two-circuit tuner with the sec ondary circuit connected in the ultra audion manner. ^ The primary and secondary coils'of the set are the stator and ndoi- re spectively, of an ordinary variocoupler The secondary tuning eomUnser may be the one formerly list'd In ;he aerial circuit of the old single circuit tuner. The other variable condenser has a capacity of .001 mfd. This condenser is included for the purpose of eradi cating the fault of the old standard ultra audion circuit, i. e., uncontrol lable oscillations. The two fixed condensers shown in the secondary circuit must lie good mica condensers that will rmC blow when the B battery Is applied, other wise the tube trsed in the set will he burned mu. The grid condenser and leak are standard It is suggested that the constructor experiment with the grid leak in this set after he ha* learned the tuning. Try varlou* Since the inauguration of ttm anti- squenl campaign a lot of trick circuits are coming out with claims that they some instances the some basis. The best way to settle beyond cavil whether your set radiates ‘or nbtrU to arrange a test with a neighbor, say a block or so away. Agree on a time for the test. Agree on a wave length,.or a series of them, for testing. For instance, have your neighbor listen for KI'KA from 7 to 7 :.'!<> on a night when they are on the air. Tune your set to KDKA. then force regeneration and oscillation to the limit, twisting the dials and producing all the squeals possible: If the neigh bor hears the squealing it’s time for you to get a real, loose coupled radio set or one of the type using radii frequency. Always Keep All Your Parts Well Separated One of tlic* most important things to hear in mind when building a, radio receiver is to keep tin* parts well sep a rated. In -a 'three-circuit receiver which is made up of two variometers and a variocoupler, had squcalFttg and howling sounds will he experienced if the parts arc not well separated! and in order to prevent,.this the two vari ometers should he placed about 12 inches apart and at right angles to each other. The variocoupler in a thiee-eircuit receiver may he placed irfidway between the two variometers. separation of Set From Battery Is Not Harmful In installing a radio receiver in a home, it is often desirable to place the storage, battery a distance away, in order to make it unseen. This can be done without fear of affecting the ac tual results obtainable from tli£ set. The length of wdre between the latter and the baMO'ry is of tittle importance; in fact the wirenets as an additional aerial apd oftep -helps along the regu lar outside antenna. SCHOLAR NOTED TOR HIS ECCENTRICITIES Many Amusing Stories Are Told of Doctor Spooner. The retirement of Wv. Dr. W. A. Spooner, the distinguished English his torian, who has been successively fel low, tutor and warden of New college, Oxford, has caused an outburst of anecdotes In the British press, for Doc tor Spooner’s habit of interchanging letters or syllables, with results that were sometimes very amusing, is fa mous wherever Oxford men are found. Indeed, the fame of “Spoonerisms” eclipsed his very considerable fame as a scholar, much to the ironic amuse ment of the victim himself. There is a good deal of doubt ns to the authenticity of many anecdotes told about Doctor Spooner, but at least the noun “Spoonerism" Is enshrined officially In the New English dictionary: “Spoonerism (f. the name of Rev. W. A. Spooner—1S44). An accidental transposition of the Initial sounds or other parts of two or more w-onls,” and Oxford slang has known the word Joyfully for r»0 years. One of the most famous Spooner isms is said to have been uttered in a sermon which Doctor Spooner’preached at Oxford. "Ah, brethren,’’ he said, “are you never conscious of a half-- warmed fish within the breast?” Who would recognize In that extraordinary sentence a “half-formed wish?" It was Doctor Spooner who, at the conclusion of the Oxford celebration of Queen Victoria’s Jubilees, called for three cheers for “our queer old dean”—an honor which that functionary might well have appreciated in spite of the adjective, hut which did little honor to the “dear old queen” for whom the celebration was held. It was Doctor Spooner also who In bicycling days Is supposed to have dismounted to "boll his Icicle." One student of New college Insisted to his dying day that the warden had rebuked him for ‘ fighting liars” In the quadrangle, and there Is a story that he took his history class severely to task for “hissing all my mystery lec tures." There Is also a tale of an un fortunate graduate whose waste of time led to the accusation that he had "tasted two whole worms.” Doctor Spooner Is said on one occasion to have read out the-first line of the hymn, “Conquering kings their titles take." ns “Kinkering ftongs their titles take” and to have proposed the royal toast, “Gentlemen, the king,” ns “Klngle- men. the gent." to the mild dismay of the assemblage. Being a kind-hearted and philosophic person, the ex-warilen of New college finds a quiet diversion in the gradual multiplication of anecdotes abyut him. nine-tenths of which, needless to say, | are apocryphal, though nope the less amusing for that trifling fact.—From the Living Age. New Refrigeration Idea Freezing with carbon dioxide Is a new method of fish refrigeration being tested at the Atlantic biological sta tion In Canada, according to reports received by the American Chemical society. The use of solid carbon di oxide, it Is asserted, has several ad vantages. The lowering of tempera ture by this means retards spoiling, and the cooling can he controlled with in wfde limits. The carbon dioxide also excludes the air while the pene tration of the Juices of the fish by car bon dioxide gas has an additional pre- servative effect. Weight f<^r weight solid carbon dioxide has twice the cooling power of artificial Ice, and It is believed that the cost of production can he kept down to about the same figure.
