Am I correct that you could home in on BBC Radio 2 long wave at Daventry from halfway across the Atlantic, getting you to within 80 miles of London ? Did you have the kit to give the direction ?
The former Radio 2 Long Wave transmitter using 1500m/200khz (now Radio 4 198khz) is at Droitwich. Daventry, closed in the nineties, was Short Wave for the Empire/World Service. Dav's claim to fame is that it provided the signals for proving the concept of radar in experiments carried out barely a mile from where I sit now.
