Radio broadcast .. (1922-30)

174 Radio Broadcast four hours because nothing will tune-out WDAF's harmonics while they have their alleged frolic, it can be expected that he will be in a different position to most other amateurs, so his feeling should not be taken as a general one. It has often been remarked that the enforced quiet hours have reduced interference from amateur stations. This is a point which I should like to hear more correctly stated. It is true that when this regulation was made, some owners of single circuit receivers got less interference, but the general interference was not altered at all. Too many amateurs are going around confessing that their sets create interference, whereas, quite probably they do not. The spark is the only type of transmitter which I know does create interference serious enough to be noticed. I think that even an IC\V set is harmless. \Vhile in New York last year, I was listening to 2RK on a single-circuit receiver, at a point about a mile distant from him, and I found the tuning quite sharp. From experiments which 1 have made from time to time in the last five years, I am inclined to believe that if interference is encountered from a CW station, the fault is with the receiver. One should never lose sight of this point. As a matter of fact, the improvement in design of receiving sets is so rapid that I think the present compulsory silent period will be lifted in a year or so. H. S. GOWAN, Kitchener, Ont. NOT ALL "APPLAUSE" Goes to broadcasters. This card, done in full colors, hove in the office not long ago "To Begin Wiih, Radio Saved My Life." Editcr, RADIO BROADCAST, Doubleday, Page & Co., Garden City, L. I. DEAR SIR: You asked some time ago for letters telling "What Radio Has Done for Me." Well, to begin with, radio saved my life. This I did not fully realize until after my doctors had explained it all to me, but now I know it to be true. Some two years ago, I found I had serious lung trouble. I tried to fight it "standing up" for a while, but soon my doctors sent me to Asheville, N. C., where I remained in a sanatorium and made no progress. Considering myself a gone goose, and preferring to die among my own family rather than passing out at Asheville, I came home, down and out. I practically gave up, and lost all interest in everything. The combined pleadings of my family and doctors to buck up, did not make any impression on me whatever. One day a strange chap came into my bedroom and began to fool around with some wires and a box on a small table near me. He did not have tnuch to say, and I was in such a state that I thought he had something to do with my funeral. I rather thought that this stranger's presence was only another indication of the complete care my family was taking of me and that this was the real beginning of the end. Then the chap said: "Say old man, try these on your head and see if they fit." I wondered whether people were now having their heads measured for burial. Anyhow he placed the contrivance over my head, and 1 don't think 1 have been before or since so near heaven as I was then. I heard a voice and music and actually believed I was leaving this earth. Making a long story short, I became as interested as a six-year-old. The set was installed on Friday and on Monday, my doctors said to me, " You have made as much improvement in the last three days as we could have expected in a month. From then on, I lived in bed with the phones on. But I did not stay there very long. . . . Not long ago I was out riding with my doctor, who remarked to me that I owed my complete recovery not to his good work especially, but to the beneficial effect of the radio set at the psychological time.

DE.VR SIR: If you have space for the following, I would like to report reception of the following American radio amateurs. I used two valve, detector and one low-frequency valve. If any of them are interested and can verify same, I would be glad of a card. Received on 25 November, 1923, about 10:30 p. M. E. S.

DEAR SIR: The sole fault I have to find with your famous one-tube knock-out reflex receiver is that users frequently run into a faulty fixed or variable crystal and as a result grow dissatisfied. This is borne out by my own experience, for I have had wonderful results, when the crystal "was feeling well" on three different occasions with all conditions other than the crystal the same. So far J have tried several crystals. With one semi-fixed crystal I seemed to get the most satisfactory results — when that was adjusted right and fastened, I could get three to four houis of perfect reception. Then I had all Chicago stations, Detroit, Springfield (Mass), Philadelphia, Fort Worth, Dallas, Northfield, Atlanta, and once, Oakland, Cal., but apparently after that favored spot lost its sensitivity, the set would
