Pretty sure that Leuchars was still available
Still at Leuchars when I was an Ops Officer in 1985. There was a survey by HQSTC of Navaids and their utility and we asked if we could decommission it as we couldn't find anyone who used it - the answer was no, just in case there was were any civil users still about.
Makes me wonder what other old equipment is still serviced and radiating around the world "just in case".
