A QSL card is a written confirmation of either a two-way radio communication between two amateur radio stations, a one way reception report of a signal from a n AM radio station, FM readio station, a shortwave broadcasting station, or a television station by a third party listener.
Amateur radio operators exchange QSL cards to confirm two-way radio contact between stations.
History of QSL cards.
During the early days of radio broadcasting, the ability for a radio set to receive distant signals was a source of pride for many consumers and hobbyists. 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 the volume of reception reports increased, stations took to sending post cards containing a brief form that acknowledged reception. Collecting these cards became popular with radio listeners in the 1920s and 1930s, and reception reports were often used by early broadcasters to gauge the effectiveness of their transmissions.
When sending QSL cards to the QSL Bureau, cards must be sorted and grouped together.
QSL cards need to be addressed correctly by designating the preferred prefix of the destination Bureau. Only the preferred prefix of the destination Bureau must be printed in the top right hand corner on the front or back of the card.
