02 THE ELECTRICAL EXPERIMENTER May, 1917 he is glad he wasn't aboard the good ship "Hardship," as they shoot men in %vartime for sleeping on duty. He was right on deck tho, all the time, and the writer could clearly read his calls to 9 ZF and answers to the boys east. The boys of the San Francisco Radio Club also made splendid reports, as did also our College Professors, who are always with us. .4 perfectly legal report was also received from a staid old lawyer in Jacksonville, Fla., who prefaced his letter with the remark that he was not trying for a prize, but being a "Radio-Bug." he just could not keep still. A well known D. D. S. in Elmira, also sent in a very complete report and called it a great night's work. I just compared two interesting letters from one amateur. 79/6. He was diligently stabbing a piece of galena and complaining about his fibrator sticking on his one inch coil. Said he did not get M.S.G. but thought he m'ould report anyway. igi/. He sent me a list of stations he hears, as long as your arm, and Itc is non' sporting a one K.W. and working as a star relay station, 1,000 niiles being as nothing to hint. I heard him from my station— clear, quick sending: prompt businesslike signatures, and abbreviations that went clear over my head. "The world do move!" PRIZE 'WINNERS. Mr. E. B. Duvall and Mr. A. P. Smith are awarded the prize of the Electro Importing Company-—their '.Xauen POZ" Radio Receifiug Set! These young men operate jointly the Radio Station. 3 AK. in Baltimore. Md. This prize is awarded for the quickest delivery of both messages, and particularly in being on the job for the return M.S.G. Xo one but the sending stations east of 9 ZF knew when the east bound M.S.G. was coming thru. If this had been a real emergency call for Government help on 200 meters, these san-e fellows would have landed the message just the same. Congratulations to them. SECOND PRIZE. Mr. W. B. Pope. 4 .A.A, of .Athens, "Geyser" Electric Water Heater The Hot Bath is Ready Continuous Flow of Water as Desired. Always Ready. You only pay for electricity as used. .^11 water that passes through the "Geyser" is thoroughly sterilized. The " Geyser" is perfectly insulated and is absolutely safe, no danger of short circuiting or electric shock. Cold to Hot Water by Merely Turning Handle. Both the water and the current act together and both controlled by the movement of ihf faucet handle. To secure hot water turn handle to the left, for cold water turn to the right, at the center both the water and current are shut off. The Supreme Court has decided that we control the absolute right to the manufacturing of "G/),'ser" Electric Water Heater. Others take warning, as we will prosecute any infringing on same.

Georgia, is awarded the Professional Wave Meter, donated by the Electro Importing Company of New York. It was awarded for long distance reception, prompt business-like delivery, and for perfect indexing, timing and marking both east and westbound messages, received in approved commercial style. From a study of the Q.R.M. map, he was seriously handicapped on both messages, and is heartily congratulated by the writer and all good radio "sports." THIRD PRIZE. Kenneth Briggs of Rochester, N.Y., 8 MG. whom you all remember as almost catching up with C. E. Hughes, the presidential candidate, with a copy of the Relay Message on October 27th, 1916, is awarded the One K.W. Thordarson Transformer, donated again by the Thordarson Transformer Company of Chicago, thru their Mr. Connors. Mr. Briggs is congratulated on his persistency, good receiving, prompt delivery and true American spirit, as he showed not the least jealousy toward several who were working against him. The Q.R.M. map showed marked interference, particularly on westbound messages, and he can thank the Q.R.T. of \V. C. Ballard, ."r.. at Cornell College, 8 NU, for giving him the chance to win this prize. I hope he will perfect his sending apparatus, and line up with the Q.R.M. League. FOURTH PRIZE. Scott High School of Toledo, Ohio, is awarded the William B. Duck's celebrated .-Irlington Tuner: for long distance reception with moderate apparatus ; diligent and persistent listening for the return message and very complete business-like report. Leander L. FIFTH PRIZE. Hoyt of Hayward. Cal., 6 SI, is awarded the Chambers Xo. 74Q tuner for the reception of arc and spark signals. This prize is awarded for the long distance work and incessant effort to line the boys up in that neighborhood to a realization that, for once. California would be put on the Relay Map. Mr. Hoyt, besides, turned in one of the most wonderful and complete reports on everything of importance that happened, from the moment the westbound M.S.G. left New York, until the eastbound message arrived in the same city. The absence of jealousv shows he is a real man an .American—and one from whom we will hear more later on. To satisfy you all. we will publish this report in this magazine, if Mr. Ho\-t's permission to do so may be obtained later. We most earnestly hope Mr. Hoyt will not find as much real cause for worry when listening in on the wave lengths from 6.000 meters uf as he heard during the relay from 600 meters down. California is surely lined up now for good work with such ellows as 6 EA for sending L.D. and 6 SI for detail work. Mr. Hoyt will make a valuable addition to the Q.R.M. League. SIXTH PRIZE. Mr. and Mrs. C. Candler—S you all know and have heard, NH. whom are located in St. Mary's. Ohio, but their "Sigs." do not stay at home. During the Presidential Relay, this station received six hard-earned credits and later stated that their transformer was not working right. They surely proved this during the last relay, as their "Sigs." were everywhere, and if it had not been for this station, lots of stations south and west would never have received the Westbound M.S.G. at all. Some who did not know 8 NH was suoposed to help on relay, reported him as Q.R.M. When you all get your stations arranged so that you can Q.R.M. boys 1.000 miles away, you are sure on the trail of efficient long distance work. This station is awarded the prize of the
May, 1917 THE ELECTRICAL EXPERIMENTER 63 Perfection Radio Laboratory of Clinton, Iowa. One Short /Caxr .Imflifyiiuj Tuner. The writer used a tuner of this make during the last relay and could hear the -Sigs." of 4 CL and 2 PM, very Q.S.A. It is a very small and compact affair and am sure 8 Nil will Imd it a most valuable addition to their station. The owner or maker of this apparatus calls it a "Cow Sucker." It is the most sensitive and reliable receiver the writer has ever used. SEVEXTH PRIZE. O. R. Terry, Stoughton, Wis., is awarded the prize of the Manhattan Electric Supply Company of Chicago. This is a pair of 3,000 Ohm Mcsco phones. They are dandies, and the writer has been using a pair for the last year. Mr. Terry made a creditable report and great record for receiving thru Q.R.M. of the worst kind. EIGHTH PRIZE. The Phoenix Radio Club of Phoenix, Ariz., is awarded the donation of Mr. Philip E. Edelman of St. Paul. -Minn. This is his latest book, "E.vperiinental ll'ireless Station.^," and it is a wonder how so much useful information has been crowded into such a compact space. This book will put .Arizona on the wireless map forever, and the prize is awarded for long distance reception, cooperation in the relay, and real genuine .-\merican patriotism in keeping quiet when necessary. INSTRUCTIONS. The prize winners may obtain these prizes by writing to the above Donees and giving your name and address, and referring to this issue of The Electrical Experimenter. Q.R.M. There is not enough space in this magazine to report all Q.R.M., but some of it was intentional, and the writer does not care to stir up any ill feeling by publishing it. If you are interested in knowing, however, who deliberately Q.R.M.'d the stations in Connecticut and Massachusetts at 10:35 p.m., the night of February 24, 1917, write to 1 IZ—R. T.
