Storeton transmitting station

above sea level. Construction of the mast was completed in 1980.[4] As of 2009, the TV transmitter serves approximately 45,000 homes.[5]

History

The Storeton site was not an original

Capital North West and Wales with studios in Gwersyllt
, Wrecsam, are also broadcast from the site.

Although located in

OFCOM documentation[7] the transmitter is listed as Storeton Wales for this purpose. Parts of those areas were previously poorly served with Welsh television services from Moel-y-Parc due to local geography, as natural landforms such as hills can block radio waves from being received, resulting in poor quality radio and television reception or even none at all, depending on the frequencies being used.[8]

The final switchover date for Storeton as part of the Winter Hill transmitter group was 2 December 2009. The official date for Storeton joining the Moel-y-Parc transmitter group with the addition of the three Wales public service multiplexes was 25 November 2009, although there were subsequent changes for those multiplex transmissions on 2 December 2009 with limited publicity.[9]

Since the transition from analogue TV to digital TV broadcasts, the Storeton site is not a relay of either Winter Hill or Moel-y-Parc because it does not receive its signals over the air from the main transmitter sites but is "line-fed" the ten multiplexes by fibre optic cable.[10]

The frequency assignments for the Storeton multiplexes (most recent changes were on 12 August 2020) are taken from the UK Digital "700 MHZ Clearance Events - Granada region" document (page 5, "The Storeton Transmitter").[13]

The frequency assignments for the Storeton Wales multiplexes (most recent changes were on 27 February 2019) are taken from the UK Digital "700 MHZ Clearance Events - Wales region" document (page 34, "Storeton Wales", relay of the Moel-y-Parc transmitter).[14]

With the changes on 27 February 2009 for the Storeton Wales multiplexes, when the corresponding frequency of each multiplex became the same as that transmitted from Moel-y-Parc, also accompanied by an increase in effective radiated power from 2.0 kW to 3.0 kw, the Storeton Wales transmissions each became a constituent part of a single-frequency network (SFN), resulting in a significant improvement in reception quality at locations where signals were being received from both sites but where neither was consistently adequate.
