4 THE PEOPLE. BARNWELL. S. C. MORE ABOUT VACUUM TUBEASAQETECTOR How a “Three-Electrode” Is Con nected in a Simple Radio Receiving Circuit. Obviously working the tube at a point on the upper ben<l of knee of the characteristic curve would produce the same symmetrical changes in the plate Circuit by symmetrical changes in the grid potential as lt # will if the tube is worked at the lower end of plat* cirmit current and the tub* would not function at a detector. Fig. 10 shows bow a three-electrod« vacuum tube is connected in u simple radio rweivlng circuit. The “B" bat tery furnishing the necessary plat* potential is connected *with its posi tive side through the phones to tbs plate. The filament is heated to the required temperature by the battery “A." The incoming radio-frequency alternating current is applied to the grid and the pegatlv'e side of the fila ment, through the “C” battery. By connecting the negative side of the filament to the midpoint of the “C" battery a positive potential can be applied to the grid by moving the slider on the “C” battery potentiome- ter up, or the grid cap jbe made nega tive with respect to the filament by moving the slider on the “C” battery potentiometer down. In practice a “C” battery is not used to force a three-electrode vac uum tube to function as a detector. kne* of the curve. However, the al ternating current applied to the grid would now produce a large decrease and a small increase of the plate cur rent. the reverse of that shown In Pig. 9.

Since the announcement * that the bureau of standards of the dcpar f - ment of commer 0 * had perfected a method of employing electric light wire* In place of acriala. considerable experiment lug hay been done by vari ous amateurs, some of whom have had good luck while other* succeeded only in blowing a large number of fuses. Engineers of an eastern electric light company have offered the following suggestions to amateurs: “First—Successful results have been obtained so far only with audion bulb nets. Crystal sets receive the signals, •but for some reason they are very weak and indistinct. “Second—No set should be used on this system without air or oil filled condensers, placed in series with either the antenna circuit or the ground circuit—preferably in the antenna circuit. „ “Third—A fuse not heavier than one-half ampere should be used In series and Just ahead of the antenna connection. -“Fourth—An ordinary separate de tachment plug—i. e., one with two blades connecting the two separate halves of the plug—is used. Only one wire is run from this plug, the other .binding screw left undisturbed. This single cohductor wire should be long enough to reach from a handy electric light socket to the table where The Instrument is located and should terminate in the fuse mentioned above. In case an externally connected con denser is used, the circuit should be run from the fu*e to the condenser and from the condenser to the anten na binding poet of the receiving net. “In acts where the condehser la built Into the instrument the connec tion from tho fuse is run directly to the antenna blading post.

SHORT FLASHES The first national radio com pass station on the Great Lakes was recently Installed. Other stations will shortly be in serv ice when the “graveyard’’ of the lakes will have lost ita terrors. It is claimed,that John Hayes Hammond, Jr., and Dr. E. L. Chaffee have invented an appli ance that insures secrecy In wireless. The system is based on principle of producing char acteristic waves to which only especially equipped receivers are responsive. Secretary Hoover’s force of “ether cops’’ may take the form of special government, detect ing stations where aerial com passes could be arranged so as to detect the direction from which interruptions come. By a series of relays, the government station nearest the violating amateur could be notified and the source of trouble stopped. Now the fans in England are having a hard time with their air. According to a report, from England there are' only 8,000 authorized amateur operators In the United Kingdom. The Lon don Dolly Mall state* that the reason for the art's tardy growth la the fact that “bam. pertog and sensei esa restric tions 1a this country prevent wlrelaes amateur* from getting practice.
