A good all round site about sound mirrors is here, even KHF gets a mention. :)

Thanks very much for that Minsterboy - fascinating that the scheme was originally planned to be that wide-ranging!

In Volume Ten - Number Ten of Bygone Kent that came out in Oct 1989, there is a very good 10 page article by D.G. Collyer entitled Testing the Mirrors - Sound Detection of Aircraft Experiments 1923-1936.
While it deals mainly with experiments carried out in the Hythe/Dungeness area, it does have some useful photos and gives an insight into how the mirrors were hoped to work. It does make the comment that "this early warning system was to cover south-eastern England from the Wash to St Alban's Head and planned for 30ft parabolic bowls at the Isle of Grain, Warden Point, Swalecliffe and Reculver, with another 200ft wall at the latter location as part of the Thames Estuary defence".
A 200ft curved wall sound mirror had already been built at Greatstone.

However, on the 23rd September 1935, a letter from the Air Ministry spelt the end of trials with the sound mirrors. It advised that work on the Thames Estuary acoustical mirror systems was to be suspended until the end of March 1936, pending the adoption of an "alternative method for detection" - presumably radar.

I dont think they were all completed?
But it would have been Whitstable/Herne Bay that sort of area.
Maybe it's big horse I'm a Londoner. :{

Where would the ones to the right of the Warden one have been located? Still on the Isle of sheppey or back towards Faversham/Whitstable?
