Yep, I know BBC and D1 come from both, but I had a signal from them before Swingate and Creteway Down started, so I'm assuming the usable signal here comes from Dover. We get a weak FM signal from Swingate here, but Classic FM from Dover is better.
Don't think I would get a signal from Creteway Down, KMFM from there isn't usable indoors. I'm in a low part of Lyminge and the hills block a lot of the signal from the Dover and Folkestone direction. I'm not officially in the BBC and D1 coverage area, but the signal is usable near windows and outside.
