AU Rights Rexérved. Regreduction Prehibited. The Fandamentals of Radio Grid Cir- cufts, Part i1, Ta yestorday's article we considered only the most fundamental and sim- {viest of grid circuits, such as are used in the ordihary type of audlio and radio frequency amplifier circuifs. Where & one-stage radio or audio frequency amplifier circuit is used with less than 43 volts B battery in { the plate circulf, such clreufts will give g00d results, and no additional élements need be added to form a complete grid circuit for the ampli- fier unit. The only precaution to be observed is to be sure that the grid return, that is, the end of the coil that goes to the fllament circuit, is conneéctad with the negative A bat | tery lead of the Alament circuit. %] Fiel some form of tuned rvadio fre- quency amplifier circuits it is neces- sary fo provide some mesny of ad- justing the blasing petentia! on the &rid of the radio frequency amplifier tube, s0 as to bring the grid of the tube to the best potential for opera- tion as @ radio frequency amplifier, and also in many casés to control the tendency of the tube to g6 into oscile lation. n The most common meéthoed of ac- complishing this result is to connect 4 potentiometer across the A battery, and to connect the grid return from | the secondary coll of the transformer | or tuning unit with the middlé or| movtable contact of the potentiometer, | as shown in Fig. 1. The potentiome- ter consists of a high-resistance ele- ment. AB, which is connected directly | across the A battery, one end béing connected with the positive terminal | and the other with the negative ter- | minal of the battery, and & movable | member, !, which makes contact with | the resistance element, but is so ad- | justed that it can bé moved from one end to the other of the resistance | element 1 RADIO’S BEST OFFERINGS TONIGHT.

RADIO MONOPOLY CASE __ TO BE HEARD MARCH 18 Federal Trade Commission to Aif Complaint Against Companies in New York. The Federal Trade Commission will | start hearings March 18, at New York, on a complaint against a number of companies alleging conspiracy to re- straln competition and create a mo- nopofy in manufacture, purchase and cale in interstate commerce of radio and other electrical devices and appa- ratus. Defendants named in the compl &ré the General Electric Company, t Anterfcan Telephone and Telegraph | Company, Western Electric Company, | Inc., Westinghouse Electric and Man- | ufacturing Company, International Radio Telegraph Company, Unkted ¥Frui*t Compan Wireless Specialty Apparatus Company and the Radio ! Corporation of America. The complaint also charges in sub- stance that the respondents “have combined and conspired for the pur- pose and with the effect of restrain- ing competition and creating a mono- poly” in domestic and tmnsoceanic radio communication and broadcast- | is. The Commission, in announcing the date for beginning the taking of tes timony in the case, said the hearings would be conducted by Edward L. Smith, of its legal staff. The com- panies, it was added, will be repre- sented by attorness. by int he | “Soft” Tube Best Detector. Two factors which should be con- sidered in buying a vacuum tube are whether it is to be used as a detector or amplifier, and whether it is to be used with a storage battery or dry cells. Some tubes ars “goft” and others “hard.” A “soft” tube is one containing more gas or air. It works best ad a detector, and the “hard” tube as an amplifier. The former requires léss plate voitage, Amplifier tubes do not regenerate as easily as “soft” de. tector tubes. C Battery Connections. The positive side of the C battery connects with the negative terminal of the A battery. The negative side connecte to the one side of the audio transformer secondary and the other terminal of the transformer connects with the grid of the tube, S gl Utility of Radio Bus Wire, Radio bus wire can be eastly bent | with the ald of two 10-penny nails | land a small piece of wood -inch | thick.

The device acts as a poten- tial divider, making it possible to ad- just the grid of the tube to any de- sired potential within the limits of the battery voltage, and varies the adjustment from a direct positive con- nection to a direct negative conmec- tion. In audio frequency amplifier cir- cuits the most common means of ad- justing the negative potential on the S T ] grid is by introducing tery in the grid circuit, ¥ig. a small bat- as shown in The C Battery. In Fig 2 A represents the A bat- tery and C the grid biasing battery ustally referred to as a “C’ battery In this case a small dry cell battery of 415 voits is connected in the grid clreuit with the positive terminal of this new “C battery,” connected with the negative léad of the A battery, and the negative terminal of the C battery connected with the grid re- turn from the secondary winding of the transformer. A study of the characteristic curves of vacuum tubes, twhich show the variation of current flow in the plate circuit of a tube with a variation in the applied plate potential, will read- | ily reveal the necessity for changing the negative potential on tha grid of the tube at its best operating point for amplification. W trom 45 to | 90 volts plate battery is used, the C battery shiould have a value of from volts. With higher plate vol- tages correspondin higher C bat tery voltages up to about 9 volts will be found necessary. CLAIM RECEPTION BETTER. | WSAI, Cincinnati, Improves.
