Re: As I only live a few miles from The Hill...
I lived in Devon in my youth and met a very nice bloke in the pub one night who'd moved just up the coast from the Bude area. He said the GCHQ station was "Paid for by the Yanks". He'd applied for a job there and didn't get it. He thought probably because his grandfather had briefly joined the communist party. Told me that there was a secret HF listening station further into Cornwall. I now know this was Penhale Sands.
