What is a QSL Card?
QSL cards are a form of post card that is exchanged between radio amateurs to confirm an on-air contact.
These cards normally detail the band or frequency used, the time and date of the contact and other technical information.
Once sent, cards are often used to confirm details for amateur radio awards, competitions, etc.
The cards can also be very decorative and are collected by some as a record of their amateur radio contacts.
It is not compulsory to send a QSL card to confirm a contact and it is considered wasteful to send one for each contact made.
