Radio Prague will become Radio Prague International from Sept.1

CZECH REP.   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
