Sherrill „ *(Radio Engineer) Now that the $Bort wavelengths are 'being so rapidly developed, there is much popular interest in the experi- menting that is being done. The re - many of the regular broadcasting sta- tions may be heard on their harmon- ies, or sub -multiples o£ their funda- mental wavelengths. Thus a station broadcasting at 36o teeters, is likely fo radiate also at wavelengths of 18o, 120, 90, 72, 6o me - sults that are being obtained on these waves of zoo meters and below are as- tonishing. Trans -Atlantic traffic is being successfully handled around a 3o meter wavelength with but four or five kilowatts of power, whereas, on the customary high wavelengths it is necessary to use about 200 kilowatts. Broadcasting too, is being develop- ed on these wavelengths. WGY broadcasts around roc) meters, and KKDKA broadcasts regularly, at about 68 meters, the same program is being sent out on its regular wavelength, In addition to . these two stations, ters and so on down the scale. These harmonics are often quite strong and may easily be picked up by the short wave receiver. In Chicago (311.), WBZ of Springfield (Mass), is often heard on its sixth harmonic, or 'on about 55 metiers. ' , It is not necessary to use a special circuit topick up these short waves, but it is necessary to use special care in the construction and arrangement of the parts. The Reinartz and , the Tickler Regenerative are both popu- lar circuits for this work, and other circuits may be used. CROSS WORD Horizontal x; A bivalve mollusk 4. Road or route 7.

A parent WINQHA1V1 �iiftANGRll>dE See Illustration The rec:;iver shown in the illustra tion above uses. the old Tickler Re generative circuit, which , is ' so wel known that the diagram need not be reproduced here. The back .,side of the receiver is shown,; and the coils from left to right are -the tickler, the secondary' and the primary. The tick- ler and primary coils are rotated with respect to the secondary by shafts which, extend through to the: front of the panel. All three of the coils are mounted on binding posts so that they may be 'changed for others when a different band of wavelengths is de- sired. Thus, with the proper assort- ment of coils, this arrangement may be used for the regular broadcasting wavelengths also. The secondary is tuned by a ' 5 plate variable condenser which, in the picture, is hidden from view by the secondary winding. The condenser which may be seen at the extreme right endof the set, is a 23 plate, andis in series with the antenna. For the shorter waves this condenser is unnecessary and may be omitted. With the coils as shown in the il- lustration, the range of the receiver is from 20 to 8o meters. For lower or higher waves, smaller or• larger, sec- ondary coils may be used. It will be unnecessary -go change the primary and tickler coils .over quite a large band of wavelengths. The coils are wound with x6 gauge DCC wire. The winding is double spaced and self supporting -being held together by, eight strips of cellu- loid stuck on with collodion. The coils are purposely mounted in the rear of the set and are controlled' by wooden shafts to .minimize body capacity ef- fects in tuning. During the fist night of f operation, this receiver brought in Austrailian 2DS, and PDX and POY.of Germany. Since then it has picked up station 4AA of New Zealand. All of these stations were in the vicinity of 40 meters. Radio Questions and Answers (Mr. Sherrill will be glad to help you solve your radio problems. Write him _in care of this paper.) W. J. B. says: "I am using a single tube,' g coil spiderveb regenerative. How can I tell when I have the right number of turns on the secondary? I am using 24 gauge wire, would No. 20 be better? The secondary is tuned by. a 23 plate condenser. What tube will give the best results?" Ans.-You can tell when you have enough turns on your secondary by the setting of your 23 plate condenser. Tune your receiver to the station with the highest..wavelength that you want to receive and note the position of your condenser plates. Remove turns from your secondary winding until you get this station best' with the ro- tary'plates almost entirely telescoped within the stationary plates. No. 20 DCC wire will be slightly better than the No., 24. A "soft" detector tube with about 16 volts on the plate will give the most satisfactory results. _o_: ers eomin 'as fasht as theykin come. - If the Grits' an U. F, O.'s both run a M. B. D. asks: --"How Tong should the antenna be when it is used in re- ceiving wavelengths from 20. -:to 8o meters?„ Ans.-The length makes no great difference if the proper size of series condenser is used. About so feet is a. good length for an outside aerial. Good results are often obtained with an antenna which is only xo or 20 feet long, HE'LL HAVE IT OUT YET To the Editur av the Advance=Toimes, Deer Sur,- Mebby ye will excuse me if I am a little late wid me letther this toime, fer, shure, lasht wake was a busy wan wid me, so it wus, It wus loike the fall am the . year wid the farrunzers, whinthey hev tin tings to do at wan toime, trashins, an earn cuttin bees, an fall whate sowin; an apple pickin, an petatie diggin, an takin up turnips, an fall piowin, impleinints to clane an put in the droivin house, fall fairs to attind an wid mebby a pollytickle elickshun Crown in fer good mist ure, so to shpake.

Afther I got away from San- dy, I began to tink over what he had said, an wondherecl cud he mane it. I knew that I had nivir caught him out in a loi in me loife, Sven at elick- shun 'toimes, whin mosht Grits will do arr say annyting that they tink will hilp thin to win. Mebby, sez I to mesilf, Sandy didn't mane it in just the same way that I thought he did at fursht.

If that was his oidea I mane to tell him whin I see him agin that he has another tink corrin to him, as me bye that wus overlays wud say, fer, shure theer isn't a man, Grit, Tory arr U.
