(Copyright, 1925, by Stevenson Radio Syndicate) SWEDEN NOW TUNES IN Reported That 11,000 Receiving Sets Sold in January. Bv Time* Special WASHINGTON, March 19.—1 tis reported that in Gothensburg, Sweden, alone, there were sold during January about 11,000 crystal receiving sets, 30,000 headsets, together with a large quantity of other parts of all kinds, the total sales amounting to almost 1,000,000 crowns, Trade Commissioner T. O. Klath informs the Department of Commerce. About 4,000 radio licenses have been taken oufcr W orth Knowing Radio frequency and regen&ration seldom work together for £he simple reason that the set becomes unstable and extremely hard to handle. Adding only one stage of radia frequency to an ordinary regenerative set is a pure waste of time, as the regeneration action is fully as good as one stage of radio.

Short Cuts Things to Know in Building and Operating a Receiver,

SO TALK through your receiving set, leave the set turned on, with loudspeaker connected, put the phone tips on the P and B terminals of the first audio transformer and use the phone as you would a telephone transmitter. • • • Neutroformers should be at an angle of exactly 57.3 degrees to the panel. To get this inclination, measure and cut out of paper the correct angle and adjust the position of the neutroformer to it. • • • If you want a C battery in the audio unit, connect the F posts on the transformers, run the negative C to this wire and hook the positive side 6t the C to the negative A battery line. • • • To restore weak 199 tubes, apply six volts for 38 seconds, then drop suddenly to 4ft volts for eight seconds. For 201A tubes, use volts 30 seconds, then eight volts 10 seconds. Cool in the Ice box. • • • If your ground wire runs under the carpet, you soon will notice extra wear where the wire raises the carpet. To avoid this substitute brass ribbon for tho round wier.

Faculty to Consist of Leading Agricultural Experts of United States —Examinations to Be Held for Enrolled Students. Hu XEA Service CHICAGO. March 19.—A national radio farm school, larger than any that has been attempted, is to take the air Monday, March 23. through five broadcasting stations in the United States. The school is the project oT the Blue Valley C-eamery Institute, which has been launched of late for the development of American agriculture. It is to be directed by C. M. Long, chief of the farm service of the institute, and is to have a faculty consisting of some of the most prominent agricultural authorities in the United States. Beginning at 1 o’clock in the afternoon of March 23. classes will be' held five days a week, in the form of lectures on important farm topics. Farmers and others with receiving sets may listen in without any further requirement on their part, but registration of their names with the institute conducting these classes will bring them copies of the lectures and related pamphlets. For Mid-West Examinations will be held for the enrolled students and certificates will be Issued to those who qualify. Although the Middle West is the territory at which these lectures will be directed, the list of broadcasting stations and their ranges points to the probability that farmers in all parts of the United States and Canada will be able to listen in. These stations are WOC, Davenport, Iowa: WMAQ, Chicago: WHK, Cleveland; KFQV, Omaha, Neb., and WDAY. Fargo N. D. They will be linked together at 1 every afternoon during '.he five days the farm course is broadcast each week. The central broadcasting point will be Chicago. Schedule The lectures will be apportioned as follows: Mondays, course on hogs, under direction of John M. Eward of the lowa State Agricultural College. Tuesdays, poultry, directed by Prof. A. O. Phillilps, head of the poultry department of Purdue versityWednesdays, dairying, to be given by a number of prominent authorities on this subject. Thursdays, legumes, including alfalfa and soybeans. An authority on each of these farm products has been chosen to conduct the course. Friday will be “question box’’ day, when the various problems of the farmer-students will be answered. EXTRA LOUDSPEAKERS Extensions Can Be Made Without Cutting Strength. Radio fans often hesitate about running a wire from their receiving set to a loudspeaker In another part of a house, because they fear that the extra resistance of the wire cuts down the strength of the signals. Actually, however, there is already so much resistance In the loudspeaker circuit that even several hundred ohms of added resistance will have little effect on reproduction. Test for Short Cirruits. Here is an idea which will 3ave net builders many a tube. After the set is •wired, tesc for short circuit by hooking your A battery to the plus B and minus B posts on the set. If the tubes light your wiring is wrong somewhere and must be corrected or the more powerful voltage of the B batteries would burn them out.

FANS GROW THIN i DOING EXERCISES DAILYBY RADIO Morning Exercises Sent Out in All Parts of „ Country,. Hu XEA Srrvit't NEW XGRK, March 19—With spring comes the return of daily morning setting-up exercises by radio. This year the stunt is more popular than ever.

Health Standard Raised It is a serious effort to raise the standard of health among life insurance policy holders. For it means more in the pockets of the organization fostering the scheme. This is true in the ease of station WEAF in New York, which, with stations WCAP in Washington and WEEI in Boston, is broadcasting daily morning calisthenics for the Metropolitan Life Insurance Company. Three separate classes are maintained each morning, each lasting twenty minutes. ' The first class begins at 6:45, the second at 7:05 and the third at 7:25. The famous chimes of the Metropolitan tower In New York are used to wake up the sleepyheads. “Reduction’* Classes Broadcasting station WLW, at Cincinnati, starts its morning “reduction” class at 8. Station WOR, at Newark. N. J., has been one of the first broadcasters to take up this form of “entertainment.” And many others throughout the country are doing likewise. Music, of the marchy, jazzy sort, accompanies the exercises. Pupils of WLW may write in asking for certain corrective exercises, which are accommodatingly given over the air all “attending” the classes. Since Jan. 5, when these classes were started, the studio has gained some 200 pupils daily, it is estimated. LONG DISTANCE RECORD New System of Transmission Under Construction.

W. Meekins reports to the department of commerce. ThlS will require three additional towers, which are now in the course of erection. The new beam circuit which will be operated by the Marconi organization in conjunction with the British Postoffice will permit messages being sent from England t® Drummondsville and thence relayed ti> Australia. Only One Borough Thirty-five thousand radio receivers were counted recently in the] Borough of Queens, New York City.
