Summary edit
| Description |
WRNY Radio Advertisement, 1928. This was Experimenter Publishing's New York City station. WRNY used several frequencies from 1925 to 1934. In the 1920s, a listing of broadcast stations in a magazine or newspaper would use wavelength instead of frequency to specify a station's location on the radio dial. The advertising logo for WRNY shows both, 326 meters and 920 kilocycles. The public was slow to adopt the new "kilocycle" terminology because they could relate to wavelengths. A radio station's antenna was a one-half wavelength long wire between two masts. The unit kilocycle (kc) was replaced by kilohertz (kHz) in the 1960s.
