DEVELOPMENT OF THE AM BROADCAST BAND
Herewith the stories of dial-jumping, ‘The Chaos of 1926’ and the fickleness of the Feds. Many of the earliest .pdfs below deal with channel assignments in wavelengths rather than frequencies; you’ll find wavelength conversion tables below as well as news copy detailing the change in lexicon through the
Much of the early dial confusion and interference resulted from the lack of frequency-control (as tubes warmed up, stations ‘wandered’) and in some cases from the Libertarian desire to move one’s station to a “clear spot on the dial” rather than stay on their assigned (and over-crowded) wavelengths. The massive mess finally resulted in stiff Federal legislation. And the radios themselves; particular those known as “squealers” had to be replaced en masse.
TIME-SHARING was an ill-fated third idea to reduce congestion when it was seen that each market had fewer assigned frequencies than it had allocated station licenses. Time-sharing worked for a short while, but as stations grew successful they pushed hard for full-time authority on their channel.
