FantomZorbin... thanks for your #8811. I did notice, driving by in Street View, there was a large "Land Acquired by .." board by the old Guardroom. Oh well, that's an inevitable fate for a large collection of Seco Huts, and another bit of my past disappeared under a bulldozer blade [along with Strubby, Eastern Radar, Locking, Bracknell, Bentley Priory [well, parts of it], Uxbridge, West Drayton].
Danny42C ... I don't think we got to use data from the Nodding height finders on the Course, but obviously the Southern Radar people on the main Ops Floor did. We did our training in Cabins on the upper level, overlooking their 'reality', with a mix of real radar data and simulator input returns, IIRC. Of course, the T82 at Watton et al didn't need supplementary devices, with it's in-built stacked beam array providing height information [although we were limited to 5000 ft vertical separation when using height-finder data].
