The expression “QSL card” or just “QSL” gradually came to be used among radio-amateurs and then more broadly as radio began to develop as a mass medium. Radio stations were keen to know how well and how far away their programmes could be heard and began to send their listeners “QSL cards” in return for reception reports. The card would include letters making up the “call sign” of the station – the system still used in the United States – or the broadcasting company’s logo or some other illustration. The card would also include a text stating the frequency and the transmitter output power, and a confirmation of when the listener heard the station.
Domestic broadcasters do not tend to use QSL cards these days, but their popularity remains among radio stations broadcasting internationally. They are still keen to know how well they can be heard in the parts of the world to which they broadcast. In the era of shortwave broadcasts Radio Prague sent out QSL cards for reception reports received. Today we also send QSL cards to those who listen to us on the internet.
For 83 years now listeners of Czech Radio’s external service broadcasts have been accustomed to hearing our specific call-sign. Both the call sign and the station’s name have changed over the years. Another small change is now in the pipeline. As of September 1, Radio Prague will become Radio Prague International. Use our audio slider for a walk down memory lane…
