VHF television services from both BBC and ITV were discontinued in January 1985 as the 405-line TV system was switched off across the UK as a whole.
Moel-y-Parc's UHF channel allocation made it a "Group B" transmitter, but with the roll-out of the UK's first digital TV services in 1998, a "Group W" wideband aerial was needed. The site reverted to being a "Group B" transmitter at

28 January 1963 - 28 October 1965
The ITV 405-line television service commenced with Teledu Cymru / Wales (West and North) on 28 January 1963.
One year later, Wales (West and North) Limited had collapsed financially, and the ITA awarded the franchise to provide the service from 27 January 1964 for the West and North Wales region to Television Wales and West, the holder of the franchise for the South Wales and West of England region.

Until the mid-1960s, it had been common practice for BBC and ITV transmitters to be hosted from different masts. Moel-y-Parc had been engineered to take both services and be capable of the UHF transmission when they arrived. Additionally (and unusually) the BBC's VHF television transmissions were on Band III as were the ITV's transmissions. Having both services on the same mast meant that the region's viewers only needed one aerial.
This was the final BBC VHF television "main station" to be commissioned. The BBC published a technical report on the mast and its aerials.

In coordination with changes to transmission frequencies elsewhere in the UK arising from the clearance of the 700 MHz band for 5G mobile phone use, the following changes were implemented. The local TV "LOC1" multiplex (carrying North Wales TV) was moved from UHF channel 56 to UHF channel 27, and the transmission ERP increased from 2 kW to 3 kW. The "Arqiva A" multiplex was moved from UHF channel 52 to UHF channel 36. The national "COM7" multiplex was moved from UHF channel 32 to UHF channel 55 and the transmission ERP increased from 14 kW to 16 kW.
With the changes on 27 February 2009, the corresponding frequency of each public service multiplex transmitted from Storeton was also changed to the same as that transmitted from Moel-y-Parc, thereby making each site a constituent part of a

. In the past, some English viewers have erected a second aerial for Moel-y-Parc in order to receive a slightly increased choice of viewing, although this practice has declined with the introduction of satellite television and the reduction in schedule variations between different ITV regions. Liverpool is located directly between the
Winter Hill transmitter and Moel-y-Parc. Many homes across Merseyside county obtain an adequate signal through their TV aerial from Moel-y-Parc, even though the aerial is pointing at Winter Hill. With the advent of digital television, this has resulted in television tuners detecting the multiplexes broadcast from Moel-y-Parc on the lower frequencies before those on the higher frequencies from Winter Hill during the scanning/retune operation, and without viewer intervention where software allows region selection or by manual re-ordering, placing the Welsh variants on the allocated Freeview EPG logical channel number entries.

at the weekend, both transmitted on VHF channel 9 from Winter Hill. Pressure for a distinctly Welsh TV station was one of the driving forces behind the construction of the Moel-y-Parc mast, along with the need to deliver television to the more mountainous interior of Wales, which was out of range of English transmitters.
As late as the 1980s, Granada Television continued to claim parts of North Wales as within its editorial coverage area, in competition with HTV Cymru Wales, who had been awarded the franchise for the whole of Wales since 1968. However, after a series of mergers in the 1990s following deregulation of commercial television, Granada and HTV Cymru Wales were subsumed into

, and thus there is no longer commercial competition between the two services. ITV Granada no longer provides any regional news, weather or local interest programmes related to North Wales.

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
