Eavesdrops

This installation has been realised in collaboration with the Dwingeloo Radio Observatory, which consists of a 25m dish in diameter run by the CAMRAS foundation. This dish is the largest radio telescope for amateurs and is operated by passionate volonteers. Eavesdrops is inspired by waterfall data, which is a visual representation of the strength of different frequencies received by the dish over time. By exchanging interesting creative conversations with Jan working at the observatory, I focus my installation on EME (Earth-Moon-Earth) signals, which consist of 1-minute transmissions from radio amateurs communicating and sharing reports of each other’s signal quality. Those encoded signals sonically consist of an array of different musical notes which are here represented by different water pumps dispensing water on a dish inspired fountain. The shape coincidentally follows the same design principles as a Cassegrain dish.

This installation was shown at the KEMA Lab in Arnhem and on location at the observatory as a prototype.

Special thanks and much appreciation to the CAMRAS foundation and every volonteer who took the time to share their passion and made this project come to light!
