HOOVER EXPLAINS WAVE LENGTH ISSUE { Assignments to Stations Rest on Determining Broad- cast Ranges, He Says. The ultimate question of clearing up the issignment of wave lengths to broadcasting stations lies In the determination of the exact, ctual broadeasting ranges of all the tions now on the air. This, it was ied today, is the belief of Secre- tary of Commerce Hoover, and the de- partment to learn these exact ranges will ask an increased appropriation from Congress for the radio inspec- tion vice When on, of > it is learned over what distances the stations as they are cquipped today can be expected to fgive lequate service, and the extent {10 which increased power will length- | o1 that range, oficials of the depart- ent believe they can assign wave lengths with little fear of interference | between stations. Should the increased appropriation allowed, an extensive studv of wrdcasting ranges will be begun and : data_will be collected for use in 1ing all the stations. It is planned S in this conection a fleet of lab iory trucks similar in design to that now maintained in the Great ke district, which, in the absence of | increased appropriation by the last Congr was bought and equipped ough sacrifices made in the salaries ind other expenses of the radio sec- tion of the department These laboratory trucks are mobile and equipped to determine the causes Il interference, as well as to check field intensities of all broadcast us. Through their use, it wohld to determine the ranges of all the stations now on the air, with power now used and probable ranges hat would result from increased Secretary | | It | i | | | the possible Hoover hopes that ulti- mately the system of broadcasting tations will include just as many plants as con be heard without interfer- from other plants over their en RAI]I[]PUTS TOWN INTO LIMELIGHT |Bound Brook’s Superpower Plant Heard by 20 Mil- lion Fans. s taken th Brook. estimat one of the n in the United made it known spots eports of the transmis new superpowered trans- the Radio Corporation of at Bound Brook, it is esti that upward of 20,000,000 per ve héard the name of the Jer town spoken into tbeir homes jugh loudspeakers and head- nes.

Work is being done cof tinuously on the transmitters to per fect modulation, and it is possible that veral changes will be made before 2.XAR hecomes a regular voice of the air under the WJZ call letters. When the station comes on the air definitely, it is understood that con { tinuous broadeasting from early in the morning until midnight is contem plated by the program department of WJZ. So far, reports that the station has been heard at night have been received from every part of the United | States, and frequent reports have been had that signals sent in the day have heen picked up with good strength from points more than 500 miles from New York City. tion ton i i [ f Rice to Name All-Star Team.

One of the most important charac teristics of a transformer is its abill- ty to change a pulsating direct cur rent into an alternating current. This in change the ting direct current in the plate sircuit of a tube into an alternating current capable of produeing the con- trolling action on the grid where the important characteristic is used vacuum. tube circuits to change from negative to positive val ues of the grid’s operating point its plate circult The manner in which this action | accomplishied may be seen by refer ring to Fig and 2 we have a pulsating current flowing in coll “P” of Fig. 1 which sets up & magnetic field around the coil direction of flow in this coil is indi cated by the arrow.

CALCATERRA, Reproduction Prohibited but is building up to a higher ie. As the current builds up the mag- _|netic field increases in intensity and the magnetic lines of flux expand |outward from coil “B” o that they cut coil “S," the secondary coil as they expand in n outward direction as shown by the arrows between the two colls. This action of the expand- ing lines of flux being cut by the wire in coil “S" produces a current in the circuit into which coil “S” is connect- _|ed. If we connect a special indicating device which can make a graph of ths current flowing in secondary zireuit, as shown by “A” we can {fnd that while the current in the primary circuit is increasing |so that the magnetic lines of fux are expanding outward, the current in the secondary circuit will flow in the direction shown by the arrow in the secondary circuit. ve. Two of the promised radio events of the Winter, the rebroadcasting of European programs and the long range transmission of radio “vision,” probably will be postponed until after the first of the year, it was learned today. Intensive laboratory work has been done in preparation for resumption of radlo rebroadcasting from London by the Radlo Corporation of America, in preparation for demonstrations this month, but it is not likely that the programs would be heard for at least another 30 duvs. The new super- power transmitter at Bound Brook, N J., which makes its debut this week, will be used. It has not yet been decided whether Germany or England will be heard in the first of the international programs, but the chances favor England, whose new super-station at Daventry is now in_use. Plans for the promised demonstra- tion of the transmission of “moving” ictures over a distance of at least 200 miles are sill in the formulative stage and will not be completed until some time in January, or later. Dr. €. Francis Jenkil inventor of the radio vision apparatus, will con duct the experiments and hopes to transmit the photographs of moving objects either between Philadelphia and Washington or Boston and Wash- ington Other interesting radio pected early in 1 tion of the Victor international tests. Current Flow Explained. After the current has reached its maximum value in the “P” circuit and begins to die down, the magnetic lines of flux which the current has ated begin to contract back into the primary coil “P" and in doing |80 they are cut by the secondary coil " while they are going in the op- posite direction as shown in Fig. The current in the plate circuit in Fig. 2 is still flowing In the same di- rection, but it is decreasing In value so that the magnetic lines of flux may be indicated by the arrows, go- ing in the opposite direction between the transformer windings. This change in direction of the magnetic lines produces a change in the di- rection of flow of the current in the secondary circuit as shown by the arrow of direction current flow in Fig. 2. events ex- are the resump- concerts and the Alternating Current in Plate. If we take the curve of the pu | Ing current flowing in the plate cir {cuit as that shown in Fig. 3, the steady or normal plate current shown by the dptted line has no effect on {the current in the secondary circuit lof the transformer because a steady | current does not produce any current lin the secondary winding.
