MODESTO, Calif., September 10.— The annual convention of the ama- teurs of the sixth radio district will be held here November 7, 8 and 9, under the auspices of the Modesto Radio Club. The convention prom- ises to be the largest gathering of amateurs the district ever has seen, according to Frank Flowers, 6ST, president of the Modesto Radio Club and chairman of the convention com- mittee. A feature of the convention will be the award of a novel trophy to the operator of the best amateur sta- tion in the district. This will be a replica of the famous Wouff-Hong, which is to be engraved each year with the call of the winning station. The committee making the award will consist of J. F. Dillon, supervisor of radio of the sixth district, one of the radio inspectors, and three other men appointed by the above two. The idea originated with members of the club, |, iyric soprano, and’ Templeton Moore, Miue. Floren 10 70 11 PAC violin solos ... . WDAF 5 Kansas City L WEAF New York e Y Pitisburgh and Paul 5% .

KFI__ Los Angeles EMPLOYS YARDSTICK IN MEASURING WAVES Technical Editor of QST Investi-| gates Average Radio Motions With Improvised Equifment. HARTFORD, Conn., September 10.— Although the average radio fan has been given to understand that radio waves are intangible things that cannot be detected except by em- ploying a very delicate receiving in- strument, S. Kruse, technical editor of QST, using methods first employed by the famous German experimenter, Heinrich Hertz, in 1888, has suc- ceeded in measuring radio waves with a common yardstick. His in- vestigation was prompted by the De- partment of Commerce ruling by which amateurs are permitted the use of short wave bands below 80 meters. The standard type of wave- meter commonly employed for such measurements has been found inac- curate for measuring the very short waves, in the vicinity of 5 meters, consequently he used an improvised method. This can best be illustrated by comparing the wave motions set up by an oscillator with the curves in a line of rope when one end is fixed and the other moved up and down with a steady motion of the hand. When two parallel wires are con- nected to the oscillator, or trans- mitter, and just the right tuning is obtained, the oscillations passing to and fro will superimpose one upon the other just as the curves in the piece of rope would if a regular mo- tion were maintained, forming what are known as ‘standing waves.” The right point in the tuning can be de- tected by means of a neon-filled tube connected across the ends of the wires opposite the oscillator. The tube lights when the wire system and the oscillator are in resonance. Now if a sliding “jumper,” or piece of copper wire, is connected across the wires, in some places the tube will go out; in others it will light When the places where the tube con- tinues to light have all been located they indicate the points of no volt- age. The distance between them is equal to half a wave length. It is a simple matter then to estimate the length of the wave with a yardstick or other unit of measurement, iTON TICKET DRIVE BEGINS FOR HOSPITAL RADIO Nurses and Volunteers in Cam- paign for Big Benefit Next Sunday. Nurses in Washington's hospitals, volunteers and others are making a concerted drive today to dispose of thousands of the 40,000 tickets for the concert of the combined Army, Navy and Marine Bands at the American League Ball Park, Sunday afternoon. The entire proceeds will be used to purchase radio receiving apparatus for all hospitals, charitable Institu- tions and orphan asylums in the Dis- trict. Hundreds of tckets already have been sold, but there are thousands yet to be disposed of to insure the in- stallation of radio sets in all of the institutions. Peoples Drug Stores, as well as the nurses and volunteers also are selling the tickets. The box seats are on sale at the Mode, 11th and F streets. A number of subscriptions for seats were received yesterday by LeRoy Mark, chairman of the hospital radio fund committee. Those who bought tickets from Mr. Mark follow: Buelah Hanson, $2; Lo L N, $5; M. W. Offutt, § Joseph- Brookbank, Indian Head, Md., $10; Helen A. Baughman, Frederick, Md., $5; Elizabeth W.

How About the Crystal Detector Receiver? It seems that about every so often we radio writers forget that there is a certain class of readers, who have been waiting for information on a particular subject, and who have been waiting for so long that they have about given up hope that such infor- mation will ever be forthcoming. Whereupon, those who have been waiting for that particular informa- tion lose all patience with us and stand up on their hind legs and roar. It is a lucky thing for us, too, that there are such men among our readers, for otherwise we would never know that we are not keeping up to scratch in our knowledge of the likes and dislikes of our readers. If you ever find that I have neglected to write about’ some information you would like to have, let me know about it. In many cases that is the only way in which I can know just what it is that you want. Just recently, one of my little reader friends said: “All these ar- ticles on how to construct three-tube regenerative sets and eight-tube neu- trodyne s and eight-tube super- heterodyne sets are all very fine and I like to read them, but that is as far as I get. I haven't the money to spend on such sets so that aside from information I get from those ar- es they are of no use to me in ening to the programs. Even a one-tube set is a little beyond what 1 can afford to spend. 1 know that a erystal set can be made for a very small sum of money and that the up- keep of such a set is practically nil and I would like to try my hand at building that kind of a set, but you tellows seem to have forgotten that such a thing as a crystal set exists or can be made. How about giving us some information on crystal detec- tor sets and details of construction of a sensitive selective and efficient crystal detector set?” There is no doubt about the - fact that fans who are located within 25 miles of a good broadcasting sta- tion can get the very best quality of reception with the use of a properly constructed crystal detector set. The reproduction obtained with the crys- tal detector is even better than that obtainable with a tube set. The s is very simple to construct, it re- quires no constant replacement of Fig 2 batteries; there is no possibility of burning out a tube with the conse- quent necessity of buying another one. The cost of the parts nec to build it, not including c phones, which must be purchased either ‘case, 1= about half that quired to bulla a one-tube outfit. Before £oiL:s on with the construe- tion of the set it will be well to give a few general facts about crystal de- tector sets, the results that can be expected from them and a general consideration of their good and bad qualities, taking up the various types of circuits which can be used in such sets and the advantages and disad- vantages of each. In the first place, if you are more than 25 miles from a broadcasting station, the use of a crystal set is not recommended. One of the sim- plest crystal detector circuits which can be used with any degree of suc- cess is that shown in Fig. 1. In this circuit a simple two-slider tuning coil is used as the tuning element. While this makes a very simple and inexpensive set, it is not a good one to use in congested districts in which several stations are operating. This type of circuit is not selective and the result will be the reception of two stations at the same time. The tuning qualities of the circuit can be improved to some extent by connecting a variable condenser of about .00625 mfd. (about 13 plates) ucross the coil as shown by the dotted lines, but this will not improve the selectivity of the set to any great extent. A much better arrangement is to use a variocoupler with the stator coil connected in the aerial circuit and the rotor coil connected in the erystal detector circuit as shown in Fig. 2 The inductive coupling in which the relation of the coils with each other can be changed by turning the rotor coil considerably increases the ¢ - tivity of the circuit so that it is pos- sible to tune from one station to an- other. The use of the variable condenser in series with the coil and the vari- able condenser across the secondary or rotor coil increases the selectivity and sensitivity of the circuit, making | it possible to get the maximum effi- ciency from the circuit. A panel and baseboard layout with complete instructions for construct- ing the crystal detector receiver shown in Fig. 2 will be given in to- morrow's issue. Peggy Albion Is Back.
