Su pcrstat ion at Chicago Soon \\ rigley Building to House Equipment; Tower 28 Miles C hicago, Feb. 6.—A new radio super station, one of the largest and most elaborately equipped In the world, will go on the air from Chicago short ly lo broadcast coast to-coast and In ternatlonal programs, it was an nounced today by the Radiophone Broadcasting corporation, which has been formed by several prominent Chicagoans to operate the station. 'J'he station, to be known as "W1IT, In the W'rigley building,” will possess 8,000 watts power and, inclusive of equipment, will cost more than J”00, lino, according to George K. Carlson, general manager. Carlson Is a for mer commissioner of electricity of < 'hicago. Work on the studios, to occupy MO square feel of floor spare on the - st floor of the Wrlgley building, lias been started and negotiations have been completed for erecting the towers and power plant near Deer field, about 28 miles from Chicago on the Waukegan road. Ex-Mayor President. William Hale Thompson, former mayor of Chicago, is president of the Operating corporation. IT. J. Herr mann, theater owner, vice president: sji. H. Maier, autmoblle man, trens urer, and .1. H. Kiel, secrelarv. “Programs will include entertain ment, religious, patriotic and educa tional features,'' said Thompson. “The slogan of the station will ire, “Boost Chicago.” Every effort will he made to keep the programs of gen eral national interest and arrange ments are being made to procure a staff of nationally known artists and bring performers here from all parts of the country.” Remote Wire Control. Carlson, who will have charge of building and operating the station, Including the studio, explained that the tower location at Deerfield was •elected following tests thSt show transmission Is exceptionally good from that point, and will he operated hv remote control wire from the studio in the Wrigley building. A Spanish bungalow will be built at the foot of the towers to house the power plant and provide living quarters for the operators, ho said. This building will Include a power room, transmitting room, control room, shops, garage, ,<i ■ ‘*ypiion room and psttn, besides the living, dining and sleeping rooms. About 25 men will be Included in the power plant staff. "An idea of the size and complete ness in construction of the plant unit may be gained hy the layman from the fact that 2S miles of copper wire will he. buried in the surrounding area between the towers to form the grounding,” said Carlson. Western Electric equipment, including some newly developed broadcasting nia-: ehinery, will be used. ANTENNAPHONE REPLACES AERIAL The antennaphone Is designed to replace the present outdoor or indoor serial. It is a thin padded disc that is placed directly tinder the telephone without In any way tampering with Hi# telephone or Interfering with its u*e. A wire connected to the anten na phone is carried to the radio re ceiver and attached to the antenna poat. >11 that ii then necessary Is to tune In. Perfect radio reception. It Is claimed, is had by Induction, using the telephone wires as an aerial. Be cause there Is no actual contact be tween the telephone and the antenna phone th»re ts established a ronden ser In series In the serial. The an tennaphone forms one plate of the condenser and the telephone the other. By moving the telephone on end off the antennaphone It ts claimed that the results of a varlatde condenser in the aerial are obtained, v. If the telephone was to he moved half ►-> off the antennaphone it. would lo^fiuivalcnt to shorteijiJrtt the out door aerial. With the use of tho an tennaphone no lightning arrester is "necessary. It is snld that the anten naphone will work any type of set from a crystal to n anper-hctrodyne. RADIO DISPELS SCOTCItMYTH Montreal, Quebec—That olil joke gboilt Scotsmen preferring church services by radio because there Is no i ollectlon plate attached thereto will have to be discarded. A report has been received at headquarters of the I'iinadlan National railways from Wll Ham Stapleton, district paseengci agent »t Saskatoon, that when the Continental Idmlted, the transconti nental passenger train of the system, was approaching Saskatoon last Sun day morning the radio operator on hoard tuned In on a service being broadcast from Westminster Presby terian church in Saskatoon.

This One-Tube Set Has Record for Short Waves; Schudt Receiver Brings in Australia, New Zealand By W. A. HCIIl'DT, JR. Of late we hear quite a lot of gos sip or the possibilities of the shorter wave lengths. One time we read of an amateur here communicating wfth another in Australia. Again, we read of great distances being covered by broadcasting stations using tiie short wave lengths. For instance, KDKA, operating somewhere around t‘»0 or 70 meters, is easily heard in Europe and With great volume. Even with all this publicity, how many have concrete ideas of how to receive these low wave length sta tions? At tiie present time amateurs are principally interested in the fre quencies between 3.7 ‘and 1.70 meters, since most of the high frequency ex perimenting is done between these wave hands. Those interested in code reception have great radio thrills awaiting them if they decide to listen in on the ultra short waves. Think of being able to listen to from three to five continents in one night. That is real J>X! One may consider this .exaggerated or, t»> use ham slang, “apple sauce,” but it is la-ing done nightly by thousands of amateurs. Of course, the one draw back is the fact that one must first acquaint himself with t lie Interna tional Morse code before he can re ceive this great 1)X. Once the code is mastered, however, you can sit hack in your chair and listen to thy world in tiie true sense of the word/ Plenty of Thrills. For the man who does not care to learn the code There are plenty <»f thrills in listening to the few broad casting stations operating on low wave lengths. As time goes on there T ng.i Diagram lit lop shows wiring of set with ono slags of amplification. At right is schematic diagram of set described with one tube only. are hound to tie marfy more broad casting stations operating on the high frequencies. In fart, many prominent radio experimenters claim that the ul tra-short wave lengths will lie used exclusively by all types of radio sta tions. Many people who read that the amateurs have been Assigned t lie wave hand from frfur to five meters laugh and think It to be one grand Joke. But it is not. The wave length band from four to five meters is broad enough to contain all naval, commer mereial, broadcasting, amateur and transatlantic radio stations without one station interfering with the other. If this small hand Is figured out In kilocycles it will run up Into tile thou sands. The photo allows the front view of the Short Wave Tuner. There are many types of cl rr til In and apparatus that can he euccesn fully used for the reception of these frequencies, yet all are nut aide to bring In the DX signals consistently. The short wave timer we are about to describe js one that has been care fully selected from several really good sets as one of the best. Tills s< t, the model of which contains onl> one tube, has been given a very severe operating test and has pi own lt“ worth In gold. One of the sofa was constructed by K. M. filnser, owner and operator of station 2rtRR, nnd Is In use there. It. Is on this receiver that he listens fo Kurnpo and New Zealand every night.

The panel should be fastened by means of two wood, screws to the wooden baseboard. Then drill all holes for the various instruments. The Inductance coll is mounted on the left side of the set with the variable con denser on the right and one the same plane with the Inductance. X'exf, mount the rheostat In the middle of the panel and slightly shove the plane of the condenser and In ductance. Directly below the rheo stat and near the baseboard Is mount ed the single circuit Jack. The tube socket Is mounted on the baseboard and directly behind the variable condenser. The binding posts, mounted on the rubber strip, me placed at the hack and left hand side of Die set as you face the back of It. We ate now remjy to book it up. Wiring Hints. One end of the primary coll Is con tiecicd to the antenna and the othe: end is connected to the ground bind ing post. Starting from the top end of the I secondary coll run a wire to one end I of the grid condenser. This same wire ia connected to the fixed plates of the variable condenser. The other side of .the variable condenser Is con nected to the mid tap of the second ary inductance and also to the posi tive filament terminal on the tube socket ,our positive filament being In turn connected to both the "A plus" and “FI minus" binding posts. Take the three fixed conden«ers and connect them all In series. Thus we obtain a capacity of about .000165. These condensers are connected In series with the lead running from the Before You Buy a Radio Receiver Here we want you to examine carefully the makes we carry Compare side by side all the types of receivers on the market today.

Kxact connections fol low: From bottom or end of second ary coil connect a lead to one end of the fixed capacity. The other end of the condenser goes directly to the plate terminal of the tube socket, from this same plate terminal a lead is connected to the top prong of the phone jack, the bottom prong of this jack going to the binding post marked "B plus.” It may be easier for the builder to follow the schematic diagram found elsewhere on this page than the word description, hut the latter will be very helpful for the average layman. Audio Circuit. fin much for the one tube set. Since the average amateur station wants a two-tube act, consisting of detector and one stage of audio frequency am-i plificatlon, a few changes must be made to convert this into a two or, three-tube receiver. For simplicity's sake we show the si hematic diagram •if the two-tube set. After the first! stage of audio any number of stagesj (within reason) can be added in the manner. jVlarger panel will also be neces nary. One about 7x12 Inches will do. The addition of a radio frequency choke coil is also necessary. The choke Is constructed as follows: Wind 250 turns of No. 30 DCC magnet wire on a cardboard tube having a diameter of 1 3 4 inches. This choke is con nected in series with the lead running from the plate to the primary of the first audio frequency transformer. Our single circuit jack i>erforce is sub stituted by a double circuit jack and the conventional audio frequency fol lowed. We ate now ready to test the set out. Connect the antenna and ground to the posts marked for them, then the “A" battery, and last of all, the “B" battery to their respective bind ing posts. T\ V. 201 -A tubes were used in the writer s set and it was found of ad vantage to use 45 volts on the plate of the defector tube. Some tubes even worked better as detectors with a« high as 90 volts on the plate. (This, of course, is for code work.l Transformers of very high ratio can be used to good advantage in the audio stages of this set if only code signals are to be received. If the set does not oscillate at first, try increasing the plate voltage. If still it does not oscillate, try Increas ing and decreasing the condensers in series with the plate lead. This set has a wave length rang* of from 40 meters to 130 meters, thus • overing two amateur l>ands (th* hands used most extensively) and many other bands of equal import ance. The Kuropean amateur stations will be found around the wave lengths of so to 1ft7 meters. Most American stations are using the 75 SO meler band. The writer believes that the receiver will prove a worth while experiment in short wave*, especially to amateur radio operators. Th® one that is the subject of this article is now furnish ing thrills for the editor of this maga zine, who is, by the way, a code Jnver and an expert in both Morse and In ternational telegraphy.
