Thank you Ricardian. Another of the RAF's "backrooms", of which many of us had little or no knowledge, now closing down. A very interesting paper by English Heritage, particularly of its early WWII years.
In particular I found the ADGB Ops Room referred to intriguing. Was this the same ADGB of the 20s/30s? The point of that ADGB was that the Air Defence of Great Britain was seen to reside in the bomber which "would always get through" rather than the fighter. RAF Bicester (another subject of an English Heritage study, with many listed pre war and early war time features) was an ADGB station, having Sidestrand and Overstrand Bombers. Perhaps the old name morphed into a new meaning when actual experience showed us that with modern fighters and Command and Control Centres the bomber often did not get through, and if it did would often not manage to hit its assigned target.
If you ever sent or received a signal in the RAF it seems likely that it went through Stanbridge at some point.
