Q: What is a QSL card?
A: Well, a QSL card is an official verification (confirmation) from a radio station that you have heard it. The term "QSL" is one of many "Q Codes" which were introduced in the early 1900's by the British government - these Q Codes were simply abbreviations, QSL meaning "I acknowledge receipt".
To get a QSL card you would normally send the station a "Reception Report", which is a report containing details of what you heard, for example, the date and time of the broadcast, the frequency you heard the station on, a summary of the content and a rating of their signal, i.e. signal strength, interference, noise, propagation disturbance (fading) and an overall rating.
In return for this information (which is useful to the station engineers) the station would issue a QSL card. MANY stations issued QSLs and a lot still do so, but most operate on shortwave.
Below are some of the QSL cards which I've received over my years of listening to radio from all over the world. I hope you enjoy them and perhaps they might stir some old memories in some of you!
