The vacuum tube has often been re- ferred to as the heart of the radio cir- cuit because of its importance in the working of any radio receiver. There are many types of tubes, audio trans- formers, sockets, condensers and other | necessary parts of radlo apparatus, but these are more or less standard- ized pieces of equipment which can be | used in most radio circuits. The true efficiency of a radio receiver or circuit | lies in the proper selection and ar rangement of the colls which go to make up the tuning elements and ra- dio frequency transformers of the sys- m. O Practically avery new cireuit has its foundation on some new adaptation of the inductance coil principle. It may be a new type of tuning element or radio frequency transformer that per- mits of maximum energy transfer from one circult to another; it may be a new arrangement of coils which brings the selectivity of the receiver to a point which permits the reception of distant stations through the most powertul local stations; it may be the application of an entirely new princi- ple of electromagnetic field disposition which eliminates distortion, clears up the signals and brings the quality of reception to the best possible level. Changes Slight in Efficiency. The changes may be nothing more than those of slight arrangement of the colls or they may be revolutionary changes involving entirely new sflml- ples of construction, but in each case a betterment of performance fs the goal which is aimed at. In many cases the changes increase the dyerall efficiency of the set, while in other cases certain qualities are sacrificed to obtain otHer more desirable charac- teristics, One of the first methods of tuning used in radio circuits were the types known as singleslide and double-slide tuning coils. rubber tubing with provisions for varving the number of turns in the circuit by using a slider contact ar- rangement which made a contact be- tween the binding post of the slider rod and any given furn on the coll. i & Figl Fig 2 . The symbol for a singleslide tuner is shown in Fig. 1. As shown it con- sists simply of a coil of wire with a variable feature by means of which the number of turns, and consequent- Iy the value of inductance between points A and B, can be varied by slid- ing the sliding contact which is con- nected with B to different portiens of lhev;;;)lL en another slider arm- is pro- ;Ild';_' wl!h‘&: instruntent; 'fijhg;n n Fig. 2, the two - circul RADIO STORE, g 6 st """ i a23aiapm WE BUY RADIO SETS SPEAKERS 4 AND PARTS ATWA A ROBINSON'S MUSIC These consisted simply of colls wound on cardboard, bakelite or hard Lincoln Radio Exclnu_a 715 9th St. NW, tuped practically {hdependent of each other and provides a method of obtain- ing much closer adjustments of the elrsuits than is pessible by the single- slider arrangement. Later, instead of using sliders for varying the number of turns in a cir- auit, the use of induetance or tap switches came into use. Thess per- formed the same function as the slider, byt they eliminated the construction §iffculties of the eliders end permit- ed a hetter control from the panel. 1t is possible by the use of two indue- tance switches to vary the number of turns in a circuit by one turn at a time by making use of the “tens and units” method of tapping a coil. With the advent of the variable condenser as & tuning instrument, however, the single-turn control gave place to the rough adjustment of ths coil by means FRIDAY, SEPTEMBER. %, 1925, I N of taps taken at every 5 to 10 tur and the use of the variable condenser as tuner to get the finer adjustment. This method of coupling two cir- cuits together with .a single coil is known as conductive coupling. The increase in the number of broadcast. ing stations made it necessary to get greater selectivity and brought indu tive coupling to the fore. This meth will be deseribed in tomorrow's article, | Russia Has 12 Stations. | Twelve broadcasting stations are now operating in Russia, according to an unofficial report made to the De- partment of Commerce. The stations are located at Moscow, Nizhni-Novo- gorod, Eilisot, Erivan, Khiva, Baku, Voronezh and Tiflis.
