What is the connection between a museum and a landfill? The museum is dominated by order, the landfill by chaos. But both are something like the ultimate cultural disposal zone. Here we have a "spark gas crystal radio" Type E 170 of the Society for Wireless Telegraphy in Berlin. A precursor of the first tube devices, a true rarity! Only the German Museum owns a second specimen. Thirty years ago, it was found in a landfill near Munich, badly damaged. The device was then passed to the Transmitter and Radio Technology Museum Königs Wusterhausen to be returned to functioning condition and ready for exhibition. To do so, plenty of research was required. And during the restoration work, only original parts were used. Some buttons even had to be re-manufactured. Nowadays, the radio largely corresponds to its original condition. And it is functional. These kinds of devices were built for mobile use during World War I but later also for the main broadcasting station of the German Reichspost on Funkerberg hill in Königs Wusterhausen.
