Radio transmitters on medium and short wave were in operation near the small town of Hörby in southern Sweden for several decades. This book tells the story of a large medium wave transmitter and three generations of powerful short wave transmitters in Hörby. One episode is the transfer of the output stage of the medium-wave transmitter to the Funkerberg Museum in Königs Wusterhausen, Germany. In the decades in which broadcasting was carried out on a large scale on long, medium and short wave, transmitter sites were established whose names themselves came to symbolise broadcasting. These included Königs Wusterhausen in Germany and Hörby in Sweden. Other examples of world-famous broadcasting locations were Allouis in France, Beromünster in Switzerland, Brasov in Romania, Droitwich in the UK, Kalundborg in Denmark and Liblice in the Czech Republic. In radio broadcasting at that time, each station had to hold its own assigned frequency and had to cover a large area, which in many cases extended far beyond national borders.
