RADIO DIGEST March 31, 1923 «.S. STATION HEARD ALL OVERENGLAND ONE MAIL BRINGS FORTYTWO LETTERS British Fans Acknowledge Reception of Special Program Broadcast by WOR NEWARK, N. J. — The remarkable ease with which British Radiophans receive the broadcasting: stations in this country duringperiods when their own local stations are shut down was emphasized by the recent test made by station WOR. at Newark, N. J., in giving a special midnight program. In a single mail last week the operators of the station received forty-two letters from fans scattered all over England. Incidentally, the test shows how thoroughly the British public have gone in for Radio, because in order to hear the program they all had to stay up until 5 o'clock in the morning. Even the most "died-in-the-wool" distance bug in this country would scarcely stay up that late for a record. Gets Humorous Letters By a strange coincidence, the fan who reported receiving WOR on a loud speaker was N. G. Baguley, of 23 The Park, Newark, England. He wrote a lengthy letter describing his set, which consisted of three stages of Radio-frequency amplification, a detector and two stages of audio. All of the letters emphasized the clarity of the announcers voice — J. E. K., who in private life is Miss J. E. Koewnig. In this respect some of the letters were really funny. One from a fan in Woking, just outside of London, wrote: "Dear Sirs (and Madame your Mistress of Ceremonies whose clarity of speech is wonderful)." Another from Margate was addressed to "The Lady Announcer of WOR." The letters give an insight to the transmission of the new broadcast stations in England, as all of them were unanimous in declaring that the modulation of all the American stations heard by them was far superior to the local stations. WEIRD SIGNALS SAID TO COME FROM MARS French War Ministry Conducts Investigation of Mysterious Noises PARIS. — The war ministry is investigating mysterious Radio signals heard March 19, which some Radio experts suggest came from Mars. The Eiffel tower, which is the most powerful station in the vicinity, did not utter the peculiar noises and no other French station emitted them, it is said. Astronomers say they do not believe another planet was signaling the earth, but they professed ignorance of the origin of the weird Radio noises. Experts agree that it was not static.

OWNS ETHER (Continued from page 1) that the broadcasters learn co-operation as have the amateurs, and this was something lacking by a majority of the plants today. W. A. Wheeler, of the Department of Agriculture, said he thought the agriculture depaartment of second importance only to mobile forces, after Hoover had advanced a new theory that the ether was government property. Sets Will Be Cheaper Major Armstrong expressed himself as a believer that Radio sets would be at a minimum in price to everyone within a year, so increasing the listeners in of the broadcasting stations. He urged that the wave lengths be regulated as speedily as possible. L. E. Whittemore, of the Bureau of Navigation, coincided with Mr. Armstrong in his views and said he believed the summer months would not experience the slump in Radio interest as was shown last year. C. Francis Jenkins, inventor of Radio pictures, asked consideration of the conference for his new device when fixing the wave lengths. A suggestion for the elimination of all spark transmitters was presented by Harold J. Powers of the Amrad. However, this issue was greeted as impracticable by quite a number of the conferees. Wave Iiengrth. Big Issue The prime questions of the conference are understood to be the re-distribution of wave lengths and elimination of interference, especially in the interest of broadcasters and Radio receiving set owners. A new survey of the wave bands assigned tentatively lastryear to different services by the committee will be made with regard to any vital changes which may have taken place during the last twelve month. Secretary Hoover is anxious to aid every service without handicapping any, particularly the mobile services such as ships and planes. There are a number of. wave bands which it is hoped can be reassigned or transferred so as to improve general conditions. Looking Ahead The First Prize Flewelling Set, designed and made by Mr. Lawrence M. Blakely, student at Georgia Institute of Technology, Atlanta, Ga., will appear in the next issue of the Digest.
