QSL Cards

QSL cards are physical postcards exchanged between amateur radio operators to confirm a radio contact, or "QSO," they've made. Each card typically features details like the date, time, location, and signal information of the contact, serving as a tangible record of their communication. They're often collectible and serve as a way to verify and celebrate successful radio connections across distances worldwide. QSL cards hold cultural significance within the amateur radio community, symbolizing a shared passion for communication and international connection.
