There were also beacons on some mountains in Wales that operated on the same frequency, so if you heard it you must be too close!

I'm afraid HF radio doesn't work like that. I worked a station on a WS19 (with about 2W AM output) in Belfast back in the 1970s (CCF network) using a WS19 myself in Brighton.
That was on 5330kHz. An easy contact as I recall. Skywave of course. My aerial was a dipole cut for the frequency about 20' above the school playground. A clear example of NVIS progagation, which would have been very common during WWII radio contacts, though little recognised at the time.
