UK Free TV shows the coverage area for a radio transmitter as a coloured overlay (orange for FM, other colours for DAB) on the grey map. We have computed the coverage by combining the terrain with the official radiation pattern. A single click will select the transmitter to view the coverage for a single site, and a double click goes to a page showing full details. Click on the buttons in the right-hand corner of the map to choose from different frequencies (or multiplexes for DAB).

John Ricketts: The BBC national mux will be in Bude by the end of 2015, the Cornwall mux will be there by September 2016. There are no precise dates unfortunately, but Ofcom have now approved the Expansion Plan proposals so this gives the green light to the local DAB transmitter build-out :

Dr N H Chamberlain:
I'm afraid you'll need to provide a full postcode for us to provide you further guidance on that. There are a number of transmitters providing coverage of the "SE Wales" multiplex carrying BBC Radio Cymru on Block 12C: 227.360 MHz which is operated by NOW Digital.
