it is also possible to receive the ITV Central (West) service from The Wrekin Transmitter. Unlike what was once the case for ITV Granada, these areas were never included in ITV Central's editorial coverage area for regional news, weather, or local interest programmes. Reception difficulties The Moel-y-Parc transmitter service area has always suffered from out of area reception from a number of adjacent transmitters or relays with overlapping coverage, or intermittent extended coverage due to atmospheric conditions, namely the transmissions from Llanddona, Storeton, Fenton, Sutton Coldfield and The Wrekin B. During the time of analogue television, parts of Greater Manchester were subject at times to co-channel interference from Moel-y-Parc because the Saddleworth relay of Winter Hill transmitted on the same frequencies, UHF channels 42, 45, 49 and 52, although mitigated by transmissions from Moel-y-Parc being horizontally polarized and those from Saddleworth being vertically polarized. Parts of the North East Wales coast where reception of Moel-y-Parc is obscured by the Clwyd Hills were served by relays of Moel-y-Parc at Bagillt, Flint, and Holywell. Following analog to digital television switchover, these relays were closed, and the Welsh regional variants of multiplexes PSB1, PSB2, and PSB3 are now broadcast to this area from Storeton, with Storeton being line-fed these multiplexes by fibre optic cable. There are nineteen other Moel-y-Parc relays broadcasting the Welsh regional variants of multiplexes PSB1, PSB2, and PSB3 received off-air from Moel-y-Parc. Digital switchover problems By December 2009, more than 6,000 complaints concerning interference from the Moel-y-Parc television transmitter had been received following the changeover from analog to digital television in the Ofcom designated "Granada" (viz. North West England) region. Many residents in Wirral and west Cheshire found the Welsh variants of television services with regional content, namely BBC One Wales and BBC Two Wales from BBC Wales and ITV Wales on the Freeview logical channel numbers displayed at the start of the EPG listing, instead of BBC One North West, BBC Two, and ITV Granada. Digital UK, the organisation responsible for the switchover, responded by telling consumers to retune their systems manually. This problem arises because the multiplexes transmitted from Moel-y-Parc with the Welsh regional content are on lower frequencies than those of the multiplexes transmitted from Winter Hill with the North West regional content. Thus when the TV tuner scans the UHF spectrum searching each UHF channel for the presence of a signal for a DVB multiplex, it
