The Switchdigital local DAB digital radio multiplex for Central Scotland is to receive a power boost later this year in order to combat incoming interference from Northern Ireland.
Switchdigital operates on VHF block 11D in Central Scotland, sharing the same frequency with the national commercial digital multiplex Digital One in
England, Wales and soon Northern Ireland. To avoid interference from Northern Ireland, including the Divis transmitter
above Belfast, multiplex operator Digital One has agreed with Switchdigital a
package of mitigation measures including an undisclosed signal boost at the Darvel
and Briad Hills transmitters. This will ensure that coverage levels of Scottish digital radio services are maintained.
UTV-backed Switchdigital has been on air since July 2001 and broadcasts stations including BBC Radio nan Gaidhael, Capital, Gold, Heart and XFM on DAB across the Central Belt of Scotland.
Arqiva owned Digital One's proposals to extend coverage in Northern Ireland and to mitigate against interference in Central Scotland are currently subject to an Ofcom consultation exercise required by law. The plans are expected to be given the green light in the Spring.
