The History of QSL Cards
During the early days of radio broadcasting, the ability for a radio to receive distant signals was a source of pride for many. Listeners would mail "reception reports" to radio broadcasting stations in hopes of getting a written letter to officially verify they had heard a distant station. As volume increased and time went on stations started sending post cards instead, containing a brief report that acknowledged reception. Collecting these cards became popular with radio listeners in the 1920s and 1930s.
Amateur radio would soon follow and ham radio operators began exchanging "QSL cards" as well. This tradition gave hams a chance to display some individual creativity and make the contact more personable.
