Denver Post, December 13, 1920, page 11:


Jazz,  Yodeling  and  Orchestra  Music  Hurled  Over  Snow-Capped  Rockies  and  Across  Frosted  Plains.


    High over the snow-clad Rockies and across frosty plains sped the dreamy strains of the "Blue Danube" waltz Sunday night from time wireless telephone station at Fitzsimons General hospital at Aurora, while an audience scattered over half the continent "listened in."
    If you had the right kind of "ears" the music was heard as tho you were it the room where the phonograph was playing into the radiophone transmitter. If you didn't, the music in the air--all around you, in fact--was unheard.
    The concert lasted for an hour and a half, and approximately 150 amateur wireless stations in Denver caught the melodies. Scores of stations in other parts of the state, and in Kansas, Wyoming and other points within a radius of several hundred miles were given the benefit of the weird, ethereal harmony.
    Jazz, yodeling songs and orchestra music were sent into the air during the concert, which was given by Lieut. W. L. Winner, instructor in charge of the radio department of the army hospital's educational service.
    "Hello, hello, 6-W-V, 6-W-V talking--Fitzsimons hospital, Denver, Colo., speaking into the wireless phone. "We will now try a new reproducer. Hello, Mr. Buckwalter, will you please call me and let me know how it sounds? Stand by, please, for the next number."
    The sweet yodeling of the old melody "Sleep, Baby, Sleep," was then transmitted thru the cold night air. The selection scarcely had finished when the regular telephone rang, and H. H. Buckwalter of 713 Lincoln street reported an unusually clear tone to the music. A fox trot, more jazz, and "Anything Is Nice if It Comes From Dixie" were heard next.
    As the concert closed, the "applause" came in from various sections of the west in a clashing of "buzzes" in the wireless telegraph receiver, to be interrupted now and then by central on Catalina Island calling her sweetie in Los Angeles over the wireless phone.
    Dr. L. G. Van Slyke, a dentist in Hyattville, Wyo., who has a private station of his own, E. M. Eagleton of Boulder and Paul Willis of Wichita, Kan., are among those who "listened in."
    Tuesday night Lieutenant Winner, who formerly was in charge of wireless instruction at General Hospital No. 2, at Fort McHenry, Md., will give another concert, the features of which will be singing by a quartet of soldiers and steel guitar playing. Thursday night he will give another concert, and Friday night his "wireless orchestra" will supply music for a dance at Manual Training High school. A loud-speaking horn, or "Magnavox," will be used at the high school to amplify the sound of the music, which will be 8,000 times louder than it is as heard over a regular telephone, Winner states.
    There are twenty-three students in the wireless school at Aurora, and two of them--C. J. Hovelin and Faunce Reed--will be graduated in about six weeks.
