 By December 2009, more than 6,000 complaints over interference from Moel-y-Parc had been received following the changeover to digital in the Granada TV region.Many residents in Wirral and west Cheshire only found Welsh channels including BBC Wales and S4C at the top of their channel listings (instead of BBC North West and Channel 4).Digital UK, the organisation responsible for the switchover responded by telling consumers to retune their systems manually.
