QSL

QSL means either "do you confirm receipt of my transmission" or "I confirm receipt of your transmission". It can also mean "please send me a QSL card".

QSL is a Q-Code.

QSL Cards

A QSL card is a written form of QSL, a confirmation of contact between two parties. Traditionally, amateurs traded QSL cards. These are usually about the same size as a postcard, often elaborately decorated to express individuality, and were mailed from person to person. QSL cards can also be used to confirm one way communication ie, to a listener from a radio station either commercial or amateur.

The minimum information on a QSL card is:

• Callsign of each station
• Time - usually in UTC
• Date
• Frequency of operation
• Mode of operation
• Signal report, usually using the [RST] code.
