What is a QSL Card?

QSL card from University Technical College Durham for British Science Week 2025

A QSL card is confirmation of a two-way radio contact (QSO) between amateur radio stations. Traditionally postcard sized, QSL cards are exchanged to confirm contact details and are often collected as souvenirs. Cards and Logbook of the World (LoTW) credits can be used to achieve various awards and are also a great way to show your on-air achievements.

A typical QSL card includes:

  • Sender’s call sign
  • Recipient’s call sign
  • Date and time (UTC)
  • Frequency or band
  • Mode
  • Signal report (RST)
  • Location and operator details

QSL confirmations can be exchanged electronically (for example via Logbook of The World, eQSL or QRZ), or on paper via a QSL bureau or direct mail.
