The Liverpool multiplex is changing frequency block from 11B to 10C tomorrow resulting in a number of stations being off-air for a few hours.
BBC Radio Merseyside, Smooth North West, Capital Liverpool, Heart North West, Radio City, Radio City 2, Radio City 3, Radio City Talk, heat, Kisstory and Absolute 90s will all fall silent on Tuesday afternoon and return officially on the new frequency on Wednesday.
The change is to allow extra transmitters to be turned on without interfering with other multiplexes in the area. The two new Liverpool transmitters will expand DAB coverage from 82% to 98% of households in the area.
The retune is part of a programme of essential work which will immediately switch-on one new digital transmitter at Moel-y-Parc, expanding local DAB digital radio coverage in Liverpool for over 160,000 listeners towards the South West of Liverpool followed by a second transmitter in May at Winter Hill that will add a further 200,000 listeners towards the North West of Liverpool.
