Many years ago, as a Senior Signals Officer in the Civil Defence Corps, we were about to set up a mobile radio repeater station very near the USAF Signals facility at Golden Pot, near Alton (as mentioned in Duncan Campbell's piece above). I went over the facility and rang the bell on the gate—after explaining what I wanted the airman fetched the Officer out (we spoke through the gate—no way were they going to open the gate) and I asked him if our little repeater station would interfere with his communications.

His reply was: "Sir, if your frequencies are anywhere near ours, we will come over and sweep up the ashes as soon as you switch on your equipment."
