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.

[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 radio transmission licence for the Capital North West and Wales service from both the Storeton transmitter on 97.1 MHz and the Wrecsam-Rhos transmitter on 103.4 MHz, filed under "Capital Wrexham and Chester", was awarded to Marcher Radio Group Limited (a subsidiary of Global Radio Limited and is valid until 4 September 2027[11] The coverage area of the transmission can be seen on the Ofcom "Wrexham and Deeside FM Measured Coverage Area" document (page 5).

[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.
