WCAP LISTS LAST PROGRAM TONIGHT ‘Will Sing Swan Song With Variety of Offerings. Navy Band to Play. WCAP, the Chesapeake & Potomac Telephone Co.’s radio station, will sing its “swan song” tonight. Before departing from the broad ting field, however, the station will return to the air early tomorrow morning for its final participation in the “Tower Health Exercises.” The closing program tonight fea- tures the concert of the United States Navy Band on the Walter Reed Hos- pital grounds. It is rather fitting that this band should head the fare- well program, as Lieut. Charles Ben- ter and his musicians have played often at this station. There will be other artists on the program who fre- quently have appeared before WCAP's microphone. Among them are “Kin” Carroll, Irma Calcert, Mme. Henriette Coquelet, Margaret Bowie Grant and George McC: Col. C. Fred Cook wi 9:30 o'clock on the reunion plans of the Blue Ridge Division. An hour earlier there will be another of the series of scientific talks prepared by cience Service. me Wonders of X-Rays” is the topic. From New York WCAP will draw the weekly concert of the Anglo Per- slans. As its “signing off” attracti the station has scheduled a spec i program by George McCauley, tenor banjoist; Lee O'Haire, banjoist and vocalist, and George trumpeter. A play by play account of the Washington base ball team's final game of the present series in Chi- cago will be broadcast by WRC, be- zinning at 3 o'clock. At the close of the game, there will be a piano re- | cital by George F. Ross, a talk by | Mary E. Turner on “Sea Food Cook- ery,” and book reviews by Mss. Nina Reed.

All Rights Reserved. The Grid Leak’s Function. In the course of the operation of a tube as a detector there is a con- stant piling up of negative charges on the grid element of the tube. This tends, if the charge becomes suffi- clently large, to prevent negative electrons from the filament reaching the place and making the tube in- operative. While the grid condenser is necessary to serve the function of keeping the grid of the tube at its proper negative bias to obtain rectifi- cation, it is also necessary to provide some means whereby the excessive negative charges may be drained off from the grid. This is done by connecting a grid leak across the grid condenser so as to provide a leakage path through which the negative electrons can be conducted back to the filament and thus leave the grid at its proper operating point. Tn some cases the grid leak is con- nected directly between the grid of the tube and the filament circuit. The grid leak is merely a very high resistance, varying in practice from ahout 1 to 10 megohms—that is, from 1,000,000 to 10,000,000 ohms. The Old-fashioned Grid Leak. The old-fashione® grid leaks con- sisted merely of pencil lines drawn between two binding post terminals on a strip of fiber, cardboard or bake- lite, The resistance of such a leak could be increased by:drawing more lines between the terminals, thus pro- viding additional paths, or by eras- ing some of the lines. At best, the value of the resistance could be guessed at only in a very géneral way. . Soon the value of having grid leaks of known values led to the manufacture and adoption of measured resistances. The value of the grid leak is not an allimportant item in satisfactory operation of a receiver, in that a receiver will operate pretty well with #rid leaks of any value between 1 and 10 megohms. Most efficient opera- tion, however, cannot be expected un- )Jess some care is taken in the selec- of this important item of a radio This to Your Radio Set! receiver. To begin with, use only grid leaks of approved manufacture. Cheap grid leaks will not keep their resistance values constant, but will change with weather conditions and age. Difference in Values. TFor reception of local stations no perceptible difference will be noted with grid leaks of different values, although most efficient operation is obtained with a grid leak of com- paratively low resistance, usually be- tween one and three megohms. For distance reception a grid leak of hg»:her value is usually more desir- able. The reason for this is that the nega- tive electrons accumulate much faster when the powerful impulses of local stations are being received and therefore a better path of low resistance must be provided to allow the charges to leak off rapidly. ‘When receiving the weak signals of far-off stations, however, the elec- trons do not accumulate so rapidly and a higher resistance is therefore required to check the leakage to the proper value. . For such -purposes when receiving distant stations a grid leak of from 4 to 10 megohms will be found more efficient. The difference in price between a good grid I and a poor one is very small. * It -is foolish to take a chance on inefficient operation merely, to save'a tew cents. “VACATION" TERMS ENDED Justices Siddons. and Bailey Sit Next on D.

Further evidence that the confuston in the ether will not reach an entirely uncontrollable state wus given today in a statement issued by the National Association of Broadcasters that more than 160 of the leading stations in the country have submitted signed pledges that they will not jump their wave lengths, but will await Federal legislation controlling their transmis- sions and , gning broadcasting frequencies. Other statements are belng received {n every mail, as all stations have been asked to signify their intentions under the present unregulated system of broadcasting. Situation Welt In Hand. ‘The association sees the “situation well in hand, and no need to fear any kind of chaos due to the operations of those now in the field.” Despite these statements, com- plaints are being received of interfer- ence with the signals of several of the leading powerful stations of the coun- through the operation of other plants on pirated wave lengths. Many it is understood, have com- of the heterodyning of the waves of Station WJZ, interference that is particularly noticeable in the Middle West. Other interference is re- ported with the signals of WLW of Cincinnati. Among the statlons that have issued statements that they will not jump their present wavé lengths are WOK Chicago; WMAK, Lockport, N. Y. WDOD, Chattanooga; KI'WB, THoll wood; WIOD, Miami Beach: WPG, Atlantic City; KFWI, San Francisco, and WBAL, Baltimore, all of which have been assigned very low wave lengths and have for several mmllh‘ endeavored to be placed in more fa' vorable bands. WOK, which s operated at Home- wood, Ill, has been particularly anxious to change its wave length, but declared that ““we do not contem: plate altering our wave length or in- creasing our power."” Although recently having boosted its power to 5,000 watts, giving it a greatly increased range, WPG plans no move from the wave igned to it. Those stations that have for more than a year broadcast their programs on the highly favorable bands known as ‘“class B,” of course, will not change their present frequencies.
