Seven U. S. radio stations last week were broadcasting pictures. Two were operating regularly, four irregularly. The last were testing out their frequencies. The stations: WGY, Schenectady, N. Y. (General Electric); KDKA, East Pittsburgh, Pa. (Westinghouse); WRNY, New York (Experimenter Publishing Co.); 3XK, Washington (Jenkins Laboratories); 2XAL, New York (Experimenter Publishing Co.) ; 1XAY, Lexington, Mass. (Donald R. Lafflin); 4XA, Memphis, Tenn. (Wrec., Inc.); 9XAA, Chicago (Chicago Federation of Labor).
These stations, one or another, are sending out still photographs, moving pictures. They are reproducing scenes enacted directly before their broadcasting machines, in grey silhouet and in complete shade tones.
