Many thanks to SWLing Post contributor and resident shortwave music specialist, Justin Moore, for sharing the following from his blog, Sothis Medias:
Holger Czukay was another musician who was fascinated with the sounds of shortwave listening. He brought his love of radio and communications technology on board with him when he helped to found the influential krautrock band Can in 1968. Shortwave listening continued to inform Czukay’s musical practice in his solo and other collaborative works later in his career. It all got started when he worked at a radio shop as a teenager.
Holger had been born in the Free City of Danzig in 1938, the year before the outbreak of World War II. In the aftermath of the war his family was expelled from the city when the Allies dissolved its status as free city-state and made it become a part of Poland. Growing up in those bleak times his formal primary education was limited, but he made up for it when he found work at a radio repair shop. He had already developed an interest in music and one his ideas was to become a conductor, but fate had other plans for him. Working with the radios day in and day out he developed a fondness for broadcast radio. In particular he found unique aural qualities in the static and grainy washes of the radio waves coming in across the shortwave bands. At the shop he also became familiar with basic electrical repair work and rudimentary engineering. All of this would serve him well when building the studio for Can. In his work with the band he not only played bass and other instruments but acted as the chief audio engineer.
