RADIO  AMATEURS  TO  GET  RETURNS

Election  News  Will  Be  Sent  from  Champaign.

    Several amateur radio operators of Decatur are planning to receive election returns Tuesday night by radio-phone and wireless. These will be sent by station 9-By at Champaign, beginning at seven o'clock. The messages will come on a wavelength of 350 meters.
    The wireless message will come every hour and every half-hour and the operator in Champaign will use the radio-phone every quarter after and every quarter before the hour, repeating what he had sent by wireless telegraphy. Herbert Georges, 845 North Mercer street, expects to take the returns and Dewey Otta will have his wireless outfit set up in Liston's barber shop.
