Digital radio in the UK is split into national, regional and local services that are combined together on multiplexes. In London there are three local multiplexes that cover Greater London. DRG, under licence from Ofcom, operates the London 3 local multiplex and is responsible for getting service providers (ie. radio stations) onto the multiplex.
The London 3 network consists of 12 transmitters spread across Greater London. From Luton in the North to Guildford in the South; Slough in the West to Maidstone in the East. The map here shows the approximate circumference of the London 3 transmission area. For a more detailed view check out the transmission plot from Arqiva (DRG's transmission provider) that will help you to see if you are within our predicted coverage area.
To check the full list of services available to listeners in any particular area, use the digital radio postcode checker.
DRG cannot guarantee coverage and local geography can make a difference. Listeners on the edges of the coverage area may require a fixed external aerial to improve their your reception.
The Digital Radio Group (London) is owned by four shareholders: Carphone Warehouse, Absolute Radio, UTV and Global Radio. The multiplex is managed on behalf of DRG by Global Radio.
