IN THE WORLD OF RADIO RADIO CABINETS BUILT IN RIGA Washington, April IT.—It is almost unbelievable, hut thousands of radio cabinets arc now being shipped from I.atvia to the I'nited Stales, according to a report by Commercial Attache C. .1. Slayer of Riga, to the lumber <li vision of the Department of Com merce. These cabinets are shipped unfinished and unassembled. They are made by schoolboys in the tech nical and industrial school at Riga, who are reported to have shipped several sets last year and are expect ing to increase the shipments to sev eral million sets. New Esperanto Station. Nearly all Europe will be able to glisten In on Esperanto programs when the station being planned by Esperantist* is put into operation. The station will he erected in Switzerland, on the top of one of the hills above Geneva, probably the Salevc. It will broadcast in Esperanto 10 Germany Austria. Switzerland, Italy, France and Spain. The cost of erecting the station, whieb will amount approximately io MS.000, is to be subscribed by the supporters of the international lan guage. Blind Radio Expert. Capt. Ton Fraser, blind member of the British parliament, is a radio ex pert an«l makes receiving sets in his spare time. RADIO v_j I’roirnm for April 18.

( Three Tube Reflex Brings in “DX” Stations ★ ★★ ★★★ ★★★ ★★★ ★★★ ★★★ ★★★ ★★★ New York Couples Dance to Orchestra Music Broadcast From Miami V-— By WILLIAM A, NCHI I)T, Jr. □' IS AVKKIS right at the height of our dancing as one of the local stations signed off for the evening. We concluded that there would be no more dancing that night, at least not through tlie medium of a radio orchestra. How ever, we must have made a mistake, for a slight turning of the dials brought in the familiar strains of a popular fox trot. Surely this was not a DX station; It must he one of the locals that we missed earlier in the night. And so we went on with tho dnnce. At tlie finish of the selection every one present was startled to hear The old familiar voice say: "W-.M-H-K, 'way down in glorious .Miami Beach, Fla.

Of course I here Is nothing wonder ful about such reception, hut when >ou stop to consider the fact that only a three tube set was being used and In the heart of the city, you may agree that pcrhaiis it was rather good reception, at that, to be able to hear the station all over the house.

It nas WHO, Kansas City. Of Course, If Was a Reflex. Now, before we go any further, we might as well confess that three-tube set used was a reflex, employing a crystal detector. In other words, three tul>es doing tile work of four. The set has two stages of radio fre quency amplification and two stages of a lirflo. Undertaking the construction of such a set a few years ago would shock \lie average radio fan. Today, however, the receiver can bo con structed and hooked up in one day, If not in less time. To further simplfy the building and eliminate the difficult winding of the speclnl Inductances we urge th» use of ready-made, specially designed radio frequency transformers. Panel I .ay mil. As in the construction of any other receiver, so it is with this, a card board template should first lie cut the exact size of the panel and then the measurements laid off on this. When the template hns been made fast upon the face of the panel, the markings may be impressed on- it with a center punch. Tlie first variable condenser is mounted two and three-quarters inches in from the left hand side of the panel and three and one half Inches down from the top. Three inches to the right of this variable condenser and two Inches from the bottom of the panel the .10 olnn rheostat Is placed. Next, three inches to (he right of the rheostat, and three and one half liidies from the top i t the panel, mount the second variable condenser.

It Is rather difficult for the average radio fan to pick out a good tube socket from the thousands of various makes which he has to pick from In a large city. However, there is one good plan that holds when purchasing any type or form of radio equipment. Always keep your eyes open when visiting radio dealers. Notice what equipment they use in their own set. Judge front the actual results—If it sounds good, purchase the make of apparatus used in the exhibition set. But that is getting slightly off our subject—we started to tell of the best method to buy radio equipment. In our estimation, the best method is to purchase the products of an old, i well-Knqjvn, reliable manufacturer. There are 10 dr 12 vt>ry well-known companies who put out exceptionally fine radio apparatus. It is not cus tomary for the real business com panies to place poor quality apparatus at the disposal of the country and thereby jeopardize their standing with the radio public. The reflex set described In this ar tide is also put up in the form of a semi finished set. where the apparatus is all mounted on the panel and base hoard, hut not hooked up. In this manner thft fan can construct the out fit by simply wiring it and yet have the satisfaction of saying that he built bis own receh er. -- ' Necessary Apparatus A list of apparatus necessary for the construction of this ideal three tube reflex follows: Two All-American type R-140 tuned K. K. transformers. One All-American type R-70I, a self-tuned R. T. transformer. One 10-ohm rheostat. (hie 10-ohm rheostat. Three tube sockets. One crystal detector. Two All-American audio trans formers. Two .00025 microfarad variable condensers. One hard rubber panel. 7x18 inches. One wooden baseboard. 7x17 Inches. One .0001 microfarad fixed con denser. One .00075 microfarad fixed con denser. sj\ binding posts mounted on a hard ruhher strip. Two separate binding posts for loud speaker of one single jack. Two attractive dials. Necessary Inis bar anil Ingenuili x/ When contpleted, the outfit is op erated with the usual "A " and “R" batteries together with three standard six volt vacuum tubes and a good loud speaker. An antenna of about 50 or f.O feel In length will operate best with the reflex. However, very fine volume and "DX" cun l>e picker! up with an Indoor aerial strung around the pic ture moulding of the room. AI>out *' or 70 feet run arouttd the room in this manner will make a very effi dent system. Interstage coupling between the two tuned TJ. F. transformers js con trolled to some extent by mounting ihe first H. F. transformer in a swivellike martyr. so that it can he adjusted to the position where it will I give the lest results. Adjusting Set. First, tune In some near-by station to maxttnum signal strength. Then, listening in the headphone#, turn off entirely the first rheostat. The signal will probably continue to be heard, owing to coupling between the two couplers. To eliminate this, rotate the first coupler slightly. When a posi tion is finally found where no signal is heard, fasten the first coupler per manently In this position and do not again disturb it. Reduced Fare.
