Radio doings (Dec 1930-Jun1932)

Page Twenty-two RADIO DOINGS March, 1931 DX PRIZE CONTEXT Here is another RADIO DOINGS DX Contest with a Grand Prize well worth working for. A great nine-tube super-heterodyne receiver will he awarded to the winner — complete with tubes; all ready to plug in and amaze you with the kind of performance you have always wanted in a radio. So much sensitivity that you cannot use all of it, even on the quietest winter night, real 10 kilocycle selectivity, a wallop that will rattle the windows if youVe careless with the vol Grand Prize . . . Angelas Super-heterodyne ume control, and a tonal fidelity that will probably make your present set blush with shame. Possibly the fortunate DX enthusiast who wins this prize may intend to use it as a secondary set in the home or give to a poor relation, but we rather imagine it will speedily take first place in his (or her) affections. For while this super-heterodyne retails for only $69.50 it does not have to take a back seat in favor of any of the high-priced receivers from the standpoint of performance. The Angelus super is manufactured in Los Angeles by Davison-Haynes Manufacturing Company, and it is through the courtesy of that company that we are able to offer one of these receivers as the Grand Prize in our March Contest. Now for the details of the Contest. The time will be Saturday night, March 14th from 8 p. m. until 1 a. m. Five hours of intensive DX-ing. The contest is open to everybody everywhere. The idea is to log as many DX stations during this time as possible, listening to each one long enough to identify it and logging the name of the musical selection heard or exact words of the announcer or other speaker. List the time heard, the call letters, frequency, and name of selection or other identifying information. Logs must be mailed not later than Monday, March 16. The winner will be announced and log published in our next issue. In judging the logs, all things will be considered as heretofore. The prize winner will not necessarily have the longest log. It is only fair that contestants in isolated sections, removed from local interference should be handicapped. Bringing in 50 stations in one location with set A may well be a greater accomplishment than logging 65 stations in another location with set B, etc. The judges will try to take all of these things into consideration, therefore it is important that you give the address where you operated your set, and make and model of receiver used. You will find the new RADIO DOINGS CALL BOOK (blue cover) invaluable in this contest. * * * KMTR to Move and Install New Transmitter Mr. Frank Doherty, owner of radio station KMTR, recently returned from Washington, where he presented a case before the Federal Radio Commission in connection with KMTR's application for removal to a new site, the installation of a new transmitter and an increase in power. Permission to move the station and install new equipment was granted, while the power increase application is still under consideration. KMTR is to move to Cahuenga and Romaine in Hollywood, the site of the old Buster Keaton studio, where a new 1000 watt RCA screen-grid transmitter, crystal controlled and with 100 per cent modulation is to be installed. The station will operate with 500 watts power, however, unless the increase is granted. The difficulty of securing a power increase is due to the fact that California is slightly over its quota in the commission's unit system of rating. Very elaborate and modern broadcast studios are to be built in the grounds of the United Artists film studios, for the bigger and better KMTR. * * * KTBI Sold to Auburn-Fuller Company Radio station KTBI has been sold to the owners of KFVD, all that is lacking being the approval of the Federal Radio Commission. The new owners also have requested permission to use all of the time on the 1300 kilocycle channel not used by the sharing station KGEF. KTBI is assigned to use half-time, and KGEF half-time. This purchase gives the Auburn-Fuller people 1000 watts and probably a good split with Shuler on the time division. * * * Mexican Stations Interfere With KWKH "Old Man" Henderson will have to direct his invectives henceforth at Mexican and Cuban stations for interfering with the broadcasting by Station KWKH, of Shreveport, La., as a report of Dr. C. B. Jolliffe, Chief Engineer of the Federal Radio Commission, has reported that they, and not stations in this country, are largely responsible for interfering with KWKH. Henderson has made an unsuccessful application to have the power of his station increased to 30,000 watts in order to overcome this interference, which he blamed, however on United States stations. Dr. Jolliffe's analysis of the complaints "show that the cause is in general outside the jurisdiction of the Federal Radio Commission and not due to improper allocation."
