The three letters – QSL – constitute one of the codes originally developed in the days of the telegraph. All codes consisted of three letters beginning with “Q”. Later some of these “Q” codes were adopted by radio-telegraphists and radio listeners. QSL means “contact confirmed” or “reception confirmed”.
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. After curtailing our shortwave transmissions as of February 1, 2011 we will continue issuing QSL cards for reception via the Internet.
August 21, 1968 – a turning point in this country’s history. The invasion of Czechoslovakia by Warsaw Pact soldiers crushed hopes of life in a freer society.
Please share your memories of that time with us. When and how did you first learn about the invasion? How did the media in your country report on it? Did you by any chance directly experience those events in Czechoslovakia or by the country’s borders?
Send us your recollections, photographs and other materials. Next year Radio Prague will be commemorating the 50th anniversary of the events of August 1968 with a special project. Become part of it.

Many thanks to SWLing Post reader, Zach, who writes:
[W]hile going through an SDR recording I’d made on Saturday, I listened to the Radio Prague program via WRMI on 5850 and was surprised to hear it was the last edition of their Mailbox program. They cited the loss of shortwave broadcasting and the movement of commenting from snail- and e-mail to Facebook as the reason for discontinuing the service.
I posted a recording of the Mailbox segment as received here on the Gulf coast of Alabama with SDRuno and an SDRplay receiver if anyone is interested:
