CB QSL Cards
Based on this collection of QSL "trading cards", there was a significant number of Decatur folks who took their CB (Citizen's Band) Radio hobby very seriously.
(For those who might need a little primer on what these photos represent....... a QSL card is a written confirmation of either a two-way radiocommunication between two amateur radio stations or a one-way reception of a signal from an AM radio, FM radio, television or shortwave broadcasting station. It can also confirm the reception of a two-way radiocommunication by a third party listener.)
