BBC National DAB
BBC National DAB is a digital audio broadcasting multiplex in the UK, for a number of radio stations which have UK wide coverage. The multiplex is owned and operated by the BBC and is transmitted from a number of transmitter sites across the country; it only carries BBC radio stations.
As of the end of 2017, more than 97% of the UK's population are within reach of the multiplex following the completion of the switching on of a fourth set of new transmitters over the previous two years which had seen the reach increase from 93%. Any further expansion of DAB radio is awaiting a decision by government on any possible digital radio switchover.

"Pop-up" services

The first to broadcast was BBC Radio 5 Live Olympics Extra in 2012, then BBC Radio 2 Eurovision launched for the first time in 2014, and was joined by BBC [Radio 2 Country], BBC Music Jazz in 2015 and BBC Radio 2 50s in April 2016.
