The remains of the mid-20th century Cooling Radio Station, visible as a partially demolished building and associated low earthworks at TQ 7730 7675, were surveyed in August 2010 by English Heritage's Archaeological Survey and Investigation team as part of the Hoo Peninsula Historic Landscape Project. Now demolished antenna arrays associated with the radio station were transcribed from historic aerial photographs. Cooling Radio Station was constructed in 1938 to house a Multiple Unit Steerable Antenna (MUSA) system which utilised a two-mile long antenna array. The MUSA array was the last major technological development in the short-wave communication era and represented the ultimate short-wave receiving system. It is believed that only two other stations using the MUSA system were built in the world. Cooling Radio Station was unique as it was controlled by an electrical phase-shifting system. In total, the receiving equipment at Cooling utilised 1,079 valves making it both complicated and expensive. The MUSA system was probably the most complex radio ever built and gave valuable service between the 1940s and 1960s. During the last stage of short-wave transatlantic communication, prior to the rise of satellites, an experimental short-wave receiving system was constructed at Cooling. The Multiple Direction Universally Steerable Aerial System (MEDUSA) had the potential to be the next major development in global shortwave communication. Cooling Radio Station closed in 1965.
