For a dependable, trustworthy radio broadcast receiver, one that will work consistently night In and night out Without fuss or bother, the writer believes It Is difficult to find one more desirable than a straight three-dia- l tuned set constructed with efficient condensers and tuning coils and equipped with standard accessories. The sensitiveness, selectivity and volume of an outfit of this type can be practically guaranteed Ih advance, and the builder can be assured that he Is not spending his money on some one's notion of a freakishly "different" receiver of undetermined worth. When he has finished the wiring and connected the batteries he will hear broadcasting, and hear It well. The writer recently completed such a receiver, Incorporating In it the acceptable Innovation of a few new tuning Inductances, and enjoyed an Instant satisfaction from It that was unusual. lie had previously made a number of popularly exploited radiofrequency sets of different design, and had spent whole evenings of patient adjustment on each In an effort to obtain good results. This orthodox, unpretentious outfit, boasting nothing more radical than some straight-lin- e frequency condensers and some different R. F. coils, produced such Immediate results In the form of many and loud stations that lie thinks peof ple who want receivers should be told about It. Parts Required. The average constructor will have no difficulty In assembling the set with the aid of ordinary hand tools. The parts required are a panel 7 by 24 Inches, of any good Insulating material ; a half-incthick wood baseboard of the same dimensions, three Gen-wl- n Lemnls colls, three .00035 mfd. straight-lin- e frequency condensers, three dinls to Jit same, one six, and one tliirty-ohrheostat, one double and one single circuit telephone Jack, five standard tube sockets, grid condenser and leak, two transformers, one battery switch, one binding post strip and the usual busbar and other incidentals. The set is most conveniently assembled In two units, the panel and the baseboard. The sockets for the R. F. tubes occupy the space between the variable condensers and a little to the rear of them. The detector socket is up In the extreme upper right corner of the baseboard, and Is followed by the A. F. transformers and tubes winding along the back edge of the board. The second A. F. tube Is In the upper left section, Its P" post going conveniently to the telephone Jack In the lower left corner of the panel. Similarly, the right-hanJack connects to the adjacent detector socket. This lay-okeeps all the connections very short and In their logical order. About 90 per cent of the wiring involved In the construction of this receiver can and should be done on the baseboard Instruments before the panel Is screwed Into position. The constructor Is advised against assembling the parts first and wiring afterward, as the presence of the protruding variable condensers will make the Installation of many of the wires exceedingly difficult. No binding posts are provided for the C battery, as this unit Is most easily connected by means of short lengths of flexible cord. The other battery connections are standard and are easily followed. The Wiring. The' wiring of the R. F. and A. F. stages is more or less orthodox in nature. The three variable 'condensers are connected directly across the respective secondaries of the Lemnls coils, with stationary plates going to the grids of the tubes and rotary plates to the filament circuit. The feature of this receiver, outside of its general effectiveness. Is the type of tuning units employed. Each one consists of a secondprimary and a ary, the wire being wound according to the lemniscate principle. Tills form confines the electromagnetic field and neutralizes the tendency toward oscillation. Tlie extraordinary length of the lemniscate curve reduces the resistance otherwise encountered in small diameter coils. The wire used Is No. 26 enameled, high capacity being avoided by a system of spared windOver all, a coil is just three ing. inches long and two and across (lie loops; the small diameter of the latter is one Inch.

Receiver, flux of each section of these coils assume by virtue of the peculiar winding scheme are such that the coils as units have completely confined magnetic fleldSi Tills property precludes the necessity of mounting the coils at particular angles in a receiver In order to prevent interstage coupling. The absence of Interaction also gives each coil a fixed and definite Inductance value. Tlie last mentioned fact Is responsible for a very desirable effect, namely, the almost exact of tlie three variable condenser readings, from 200 meters right up to 600. Different aerlnl lengths seem to have little Influence on the first condenser reading, the variation at three different locations being not more than one point on a 100-unscale.

Radio Digest Chicago Fan DX Champ; Makes Daylight Record What Is believed to be a record for daylight reception was hung up by KFI, Los Angelea, when a football game, broadcast from a remote control In the Los Angeles coliseum, was received la Chicago, commencing at 2 :35 p. m. Central time. With two grid contests scheduled, the whistle blew for the first game at 12:30 p. m.t Pacific time, and It was reception of this game that brought a Chicago radio fan Into prominence as a daylight DX champ. Undoubted proof that this daylight transmission and reception is not freakish is found In the fact that 5,000 students of the University of Iowa heard an entire Iowa-U- . S. C. game In Los Angeles and broadcast from KFI. Hundreds of letters and telegrams on both days Indicated that daylight reception of KFI in the Central and Midwest states Is general. Daylight reception over great distances on extremely short waves Is not unusual, but KFI was on Its normal wave length of 407 meters for both games. Learn How to Solder Before Building Set This business of soldering radio sets Is eusy once you get the knack of It If possible to use an electric Iron It will be found that soldering becomes still more child's play. And don't use anything but rosin core solder. You dont have to bother about applying the flux before tlie solder for Its already In it. Just see that the two things to he soldered are clean; then get your iron hot and touch It to the metal for a few seconds to get It hot. Now touch your iron to the solder, retaining some of It at the tip of the iron, touch the tip of the iron to the place to be soldered and the solder will run'off the iron, making the Joint and its all over. Burnt Tubes Useful Use your burnt-ou- t tubes as a battery connector. Break the glass, sol der leads from the battery to thr wires Inside the brass shell and fir tlie shell with sealing wax. Now connect the battery leads from the wiring of tlie set to a socket arranged con veniently on the hark of the cabinet It Is a simple matter then to "plug lq. of many other!
