They used to broadcast it into Europe during the Cold War on 648 kHz MW using an absolutely ridiculous 500 kW transmitter and an aerial system that developed 2 MW directionally. This got shut down in the early '10s then was taken over recently by none other than the famous offshore radio pirates Radio Caroline who use it on a much more modest 1 kW. They still have their pirate radio ship but I think its transmitters got smashed up by the government in the '80s so they relay to the old BBC World Service site over 4G.

You can still hear the World Service on 198 kHz longwave after 0100 BST in much of Europe, they even shut down Radio 4 with the national anthem just before like it's the '50s or something. It's a delightful anachronism.
