UK DAB coverage: latest data reveals expansion

Latest Ofcom data reveals how the UK's DAB digital radio network has been expanding, with additional transmitters and power boosts continuing to improve coverage over the past couple of months.

As there is a lag between new transmitters going live and the data being published, listeners may have already noticed some improvements in recent weeks. And new multiplexes and coverage boosts, particularly relating to Lincolnshire and Suffolk were previously announced by the multiplex operator. New sites that have gone live in the last four weeks may not yet appear in the Ofcom data.

The industry is currently working towards the end of a programme of coverage boosts for both BBC National DAB and local DAB multiplexes.

From newly published information, here's the latest list of new transmitters and coverage boosts, plus effective radiated power (ERP) in kilowatts (kW), where available. New sites are also listed with National Grid Reference (NGR).

In some cases a power reduction is noted - as more transmitters are added to a single frequency networks carrying DAB stations, some optimisation is needed in order to avoid interference.
