Technical equipment on board the original Cheeta was relatively primitive and
largely home built by William Petersen, a bicycle mechanic and amateur radio enthusiast.
He built the original FM transmitter, largely from an old taxi radio, as well as the
antenna installed on board the ship.
Cheeta 2 had more sophisticated, Siemens professional equipment on board, including 4 reel to reel Lyrec tape recorders and a mixer to play back pre-recorded programmes.
Later when facilities were built on board for live programming they were equipped with 4 Garrard turntables (2 in the studio and 2 in the control room) with Ortofon Pick ups on a special arm, which kept the pick-up in the track even in windy conditions.
Landbased studios in Malmo were equipped with Ampex, Lyrec and Movic tape recorders; Garrard turntables with Ortofon Pick Ups; Neumann, Sennheiser, Pearl and Bauer Microphones.
