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-Part 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 acting as an off-air relay of Moel-y-Parc for these transmissions.
