The Museum of Flight at East Fortune seems to have come in low to avoid radar cover, and delivered its own Radar Room to satisfy some of the needs of those interested in comms:

See vintage radio, radar and avionics equipment. Open Wednesday 10:00-12:00, 13:00-16:00, subject to availability.

Even though it's been there for a few years now, it doesn't merit its own page or further details on their main site, despite having been described in reviews as "packed with early radar equipment from the Second World War":

But if you follow the link to their Interactive Map, it shows you which hut it is located in, near Hangar 1 (Military Aviation) and the west of the Vulcan.

Great piece of initiative. Worth pointing out that one of the staff at East Fortune is a former researcher for the Historic Radar Archive; I imagine he'll have had an enormous input into this.
