4S6TMP.com — Customizable printable QSL cards for amateur radio
QSL cards are physical confirmation cards sent by amateur radio operators to confirm two-way radio contact (QSO). The term "QSL" comes from the Q-code meaning "I confirm receipt of your transmission." QSL cards are a cherished tradition in amateur radio, often collected and displayed.
Standard QSL card dimensions are 5.5 inches × 3.5 inches (140mm × 89mm), the same as a postcard. This size fits in standard photo albums and postcard holders. The front typically shows the operator's callsign, QSO details, and often a photo or design representing the station or location.
For digital QSLs (eQSL), the card can be saved as an image and uploaded to eQSL.cc, QRZ, or emailed directly to the other operator. Many operators appreciate both physical and digital QSLs.
