Not only did the plate

The plate circuit of the tube is connected to a circuit containing an inductance 1. and a capacity C, which together form a tuned circuit, between the points X and Y. 1, adjusting the value of the variable lohdenser. the natural period ot t ,e tuned circuit between X and Y ■ n be made the same as the frequency of the alternator furbishing the alternating grid potential applied tn the grid circuit at T-T. When tills idition is reached, the tuned circuit k tween X and Y becomes an infinite impedance in the external plate circuit. The potential variations be-l.-.een X and Y are now maximum and :.re exact amplified reproductions of lie potential variations applied to the gid circuit by the alternator. When a three-electrode vacuum lt.be is used ns a source of undamped alternating current, it is not excited by an alternator connected to the grid circuit. Instead some of the output us the plate circuit is coupled back to the grid circuit, thus making the tube self-exciting. Fig. XXXVII shows lew this is accomplished. in place of the alternator that was connected across the grid circuit at T-T to externally excite the tube by i pplying an alternating current to the grid circuit, tiiere is an inductance 1. The two coils forming the inductance I and I, are placed close together so that the potential variations that exist between X and Y will be transZ2ZBT \L-J2 t ~T * W% ? r 'I I 'rrred from L to the grin circuit through the medium of the coil 1, hith has replaced the alternator.

The grid potential variations imI'ressed across the terminals T-T by 1 >e coll 1 have the same effect in the i'ate circuit as a potential K (when ’'is the amplification factor of the ' 1 >e) times as great applied directly 1 the plate circuit.

The amplitude of the oscillations will neither increase nor decrease. Should the potential variations in the plate circuit be greater than the potential operating in the tuned circuit, between die points X and Y, then the oscillations in the tuned circuit will increase In amplitude until the tube becomes saturated. At tills point the upper uud lower bends of the characteristic curve keep the amplitude of tlie plate circuit oscillations from further increasing ns die amplitude of die grid circuit oscillations ure increased. SOME TRUTHS ABOUT STATIC It Exists In All Seasons and Can Be Reduced by Several Known Processes. In an exceedingly interesting article In Kadlo Merchandising, John Walker Harrington discusses the question of summer static. “What are the facts of static?” he asks. "Static consists of strays or of certain electrical disturbances which must be counteracted if we would have perfect transmission. It furnishes a means of relieving the tedium of success, Just as engine troubles keep the automobilist from drifting into the calm of a smug complacency. It is not well for a radioist to be too sure of himself, and static is an antidote to inflation, which Is Just as good in winter as it is in summer. There is static when there in snow and rain—and plenty of it when the

thunder rolls. As there is usually more lightning In the hot months than In the cold ones, we are likely to have a little more static in warm weather. “Tlie reduction of static is a process which has its own technique and is ns iqucli a part of the game as the meeting of storm conditions is an essential factor in navigation. By making more use of tlie three-electrode bulb, by tuning receiving instruments more sharply, by employing directional receiving antennae so that the loop is turned toward the point from which tlie message is coming, static may be, and is. reduced and even eliminated. The amateur knows it thoroughly well, and the dealer knows it. It has merely become the custom to speak in awestruck tones about this condition as though everybody would be deeply offended. if it were not regarded as something to lie dreaded and feared.”

TIPS TO RADIOISTS 'Die Buffalo News says: “By throwing a kiss by wireless a Buffalo girl will christen the new broadcasting apparatus." Who warts to be kissed in linear? A Freehold (N. J.) paper suggests that some genius arrange a radio set for the farmer's plow handles, so he may be entertained while covering the many weary miles of furrows. 'The radio presents great possibilities In tjie way of travelless honeymoons. In their little nests the newlyweds can hear tlie roar of Niagara, the waves beating on the seashore or the clerk in a $lO a day hotel quoting rates. An appropriation of $68,000 has been asked of tlie city of Chicago to purchase a further supply of radio apparatus for its police department. Chicago claims to be the first city to apply radio to police purposes, and it has found this crime-detecting utility a great success. Recognizing the popular demand for radio outfits, plans for tlie construction of a new apartment house in St. Louis, Mo., call for the installation of n large receiving set pn the roof, which will be connected witli each turn on a switch and iiear radio concerts and programs. An estimate based on manufacturers’ reports show that more than $5,000,000 a week is being spent on radio equipment in the United States. Since the new art became popular in Canada the increase in sales lias increased 100 per cent each month since December, the month of April showing an estimated increase of several thousand per cent in sales over December, 1919. The unemployment problem of engineers and electrical technicians has been solved by the radio boom, according to a report Issued by the Federated American Engineering Societies. Since January 1 the society has placed in employment more than - 900 engineers, and is continuing its placement the rate of 20 a day. Electrical and mechanical engineers benefit mostly by the growth of the new Industry,
