One of the earliest radio broadcasting events, Lee De Forest's broadcast of the Wilson-Hughes presidential election returns from the De Forest laboratories, Highbridge, New York, November 7, 1916. An estimated 7,000 radio listeners within 200 miles of New York City heard election returns provided by the "New York American" newspaper offices, interspersed with patriotic music. The photo shows chief engineer Charles Logwood operating De Forest's 500 watt transmitter using two of his new high power "Oscillion" triode vacuum tubes "(visible center)" at a plate potential of 1500 volts. In the foreground is the phonograph, which played "The Star-Spangled Banner", "America", "Dixie", "Yankee Doodle" and other patriotic songs between returns.
