= { . 38.—The Honeycomb Coil. } EXPERT ADVICE ON RADIO H { BY A. HYATT VERRILL, Expert on Radlo Technology. Honeycomb ooils ace very useful Instruments either for a crystal set r a tube sef. They may be used s an inductance or tuning coil with » single circuit set, as coupled coils, as ticklers or as loading coils. More- over, they are not at all difficult to make. For various length wave re- ception you may use several coils of different sizes, switching or plugging in the one desired, or if you prefer vyou may make a tapped coil to re- celve waves of any length. To make a honeycomb coil which will have a capacity up to about 2,000 meters is a very simple matter and if you work carefully and neatly the result will be a coil as efficient and as good in apperance as one bought ready made. The materials required are: Cotton or silk covered copper wire No. 24 <ize; a_formica or similar composi- tion tube 1 inch in diameter and 1% :nches long; two formica, bakelite or other compogition discs, 6 inches in F STTTTTEST NN aiameter and % inch thick; two discs of %-inch wood of exactly the right size to fit snugly inside the tube, and @ ten point switch and the necessary binding posts, base or panel and crews for mounting. SCWith vour compasses or dividers draw a circle 1 inch in diameter on each of the two discs and then with the dividers mark off nine points equidistant from one another around the circumference of the discs. With a pencil and straight edge. draw lines from each of these po'n:-_(n the center of the discs and then with the Qividers mark points % inch distant from each of these radiating lines and through these draw parallel lines as shown in figure 1. Now, with a fine hack saw. cut away the portions of the dises between the lines so as o leave nine spokes or arms. each i inch wide, as indicated in dgure 1. Sealing Wax Used. Fasten the wooden discs in the ends of the tube by means of very small screws or brads, with the heads well countersunk. Cover the heads with v y ce o f the sealing wax. Next place one o large composition discs on one ;‘\‘1 tof be and, centering it by means Setue circle you have of the one-inch upon it. fasten to the wooden draw “Mhe end of the tube with dis screws, as shown in figure ¥ Repeat the operation with the oth- er composition disc. being sure to have the spokes or arms of the discs |come exactly in line. With a pencil ;number the spokes from 1 to 9 on one |@isc and mark those on the other to icorrespond, placing the numbers at the inner ends of the arms and on | the outer surfaces of the discs. Then bore two small holes through arm close to the tube and the other close {%o the outer end of the arm, as in {A. B., figure 1. Thread one end of the wire through the inner hole, A, leaving about six inches free, and fasten it to the arm on the inner side by means of sealing wax. Then commence to wind the lcoil by carrying the wire from No. 1 arm on one disc up over No. § arm on the other, then down and around the tube, over the wire where you started, then over No. 2 or the first \disc, up and over No. 7 on the oposite disc and so on until the winding R e y OUTLAW RADIO CALL. (Station on Swan Island Has Strange Position. Off Honduras, in the Caribbean, lies (a little piece of land called Swan iIsiand, where Americans have lived for many vears, although the nation- ality or ownership of the island has never been decided. On_ this “island ‘without a country” the United Fruit Company has a commercial radio sta- tion and uses the call “U S, which, however. is not a United States call, | But an outlaw call chosen by the com- pany In 1909. Although Italy owns the three letter calls from U P A to U Z 2, “U S does not come within |the control of that country any more than does the island itself. It the island came into the posses- ston of the United States the station would lose its identifyimg call, as all United States calls_begin with the letter & or W. RECENT NAVY TRANSFERS. Lieut.

The first tap should be taken at the sixth layer, by making a twisted loop in the ire over one arm. as in figure 4, and then con- tinuing with the winding. Make taps at the sixth, eighth, tenth, twelfth, seventeenth, twenty-second, twenty- seventh, thirty-seventh and forty- seventh’ turns and keep on winding on layers until sixty layers have been wound on. Then carry the wire to the No. 1 arm, run it through the small hole at the end of the arm and fasten with sealing wax, leaving a free end about six inches long. The coil should now appear somewhat as | in figure 5. The next step is tof solder wire to each of the tap loops and then finish the coil by wrapping it with Tirro or other good grade ad- hesive tape, with a sirip of strong cotton or linen cloth soaked in shellac and drawn tightly areund while the shellac the coil is still “tacky.” 1.8 L | | Finally. mount the coll on a suitable | base or panel by means of upright supports attached to the ends of the coil at the bare centers of the com- | position discs as shown in figue 6.

The other end wire is led to a binding post and | a wire is also led from the switch | arm post to another binding post, fig- | ure 7. Should you prefer several coils of | different wave lenghts, instead of the ! tapped coll you can make them in! ting the taps. Where these honey-| comb coils are to be used in place of a loose-coupled or vario-coupled ductance both coils should be ta but in this case four taps taken | at every five layers and three more | at every succeeding ten lavers will| do for the primary coil. Almost an standard circuit may be used with honeycomb coils, but if used as a tickler the tuned plate circuit, figure | 8. will be found very satisfactory. In this, the honeycomb coil takes the place of a variometer and will give | a far wider variation in wave lengths | than the latter instrument. In case you wish to use honeycomb | coils of various sizes, to be plugged! in and out, a very neat and satisfac- tory arrangement is to connect the end wires of the coil to binding posts mounted directly on the bars central portion of one of the ends. Then It is merely necessary to con nect these binding posts to the regu-| lar aerial and ground posts with your detector by short pleces of wire.
