The Shortwave Guild shares and demonstrates the development of radio communication from 1900 to 1960. This period saw significant advancements, using both telegraphy and voice as communication methods. These technologies were utilized across various sectors of society, such as maritime navigation, defense, law enforcement, the postal service (telegraphy for telegrams), the railway network, the resistance movement during World War II, the Cold War, and by amateur radio enthusiasts in Denmark and worldwide.
In our radio room, we operate an active amateur radio station broadcasting live to the world using our call sign OZ5NYV. During the first weekend of May, coinciding with Denmark’s occupation and liberation, we use the historic call sign 5P2WW (a call sign from the past). Both call signs are specially designated for the Nyvang Living History Center. Alongside the active radio station, we also explain how radio communication works.
The Shortwave Guild participates in the annual reenactment of the Danish resistance movement around May 5th, when Nyvang is "occupied" and later "liberated." As radio communication played a crucial role in maintaining contact between the Danish resistance and England, we showcase the methods and radios they used. We even have a replica of the most commonly used radio, as many of the originals no longer exist. A group of amateur radio enthusiasts built a few replicas based on wartime schematics, and we are fortunate to have one of these in our possession.
In addition to the radio demonstrations, we offer espionage-themed challenges for children—and adults, if they dare. After all, it takes courage to gather intelligence from the Germans!
We have received considerable assistance from the Experimenterende Danske Radioamatører (EDR – the Danish Amateur Radio Association) and several private contributors who helped us acquire period-specific radios and other equipment from Nyvang's historical era. Without their help, the guild would not exist.
