In October 2007, the Whitehaven, Eskdale Green and Gosforth transmitters switched off their analogue BBC TWO signals and switched on their digital transmitters for the main channels, a process completed locally on 14th November 2012 when all their analogue signals were closed down and replaced with a full digital service.
