Of the many BBC Local Radio stations which you could hear on MW there are only 6 left: Norfolk, Gloucestershire, Somerset, Derby, Guernsey and Cumbria. As soon as Radio Romania Actualitati shuts down at 22:00 UTC you can hear them with a local program. Later in the night they switch to a relay of BBC Radio 5 live.

Mr. Andy Stevenson, operations engineer at the BBC Technology group was so kind to confirm my report by email. He included a link to a site which shows the antennas in Carlisle: https://tx.mb21.co.uk/gallery/gallerypage.php?txid=1452
