South East Wales, to improve signal in areas such as the coastline of SE Wales, where the signal of the SE Wales multiplex from Wenvoe is weak due to hills and cliffs. Kiss 101 on FM is also broadcast to South Wales from the Mendip transmitting station, on a frequency of 101.00MHz. A strong 40kW directional beam towards SE Wales delivers a strong indoor signal with stereo audio available in SE Wales. The signal from the station for Kiss 101 also penetrates the Welsh Valleys and the Brecon Beacons. Heart & BBC Radio Somerset, on 102.60MHz and 95.50MHz respectively, also deliver stereo reception to SE Wales, albeit a bit weaker than Kiss 101. D1 National, SDL National & Somerset digital radio multiplexes can also be heard. Visibility at night The Mendip transmitting station is clearly visible on a cloudy or clear night from SE Wales, such as in Penarth, Vale of Glamorgan. Radio Mendip broadcasts FM (analogue VHF) radio for BBC Radio Somerset and the Severn Estuary regional service Kiss 101. Mendip also transmits high power Digital Audio Broadcasting (DAB) signals for the Digital One, Sound Digital and BBC National DAB multiplexes, using a directional antenna for the South East Wales local DAB multiplex to improve coverage in parts of the Vale of Glamorgan and Cardiff that are in the shadow of the Wenvoe Transmitting Station. An additional DAB multiplex, MuxCo Somerset, was awarded a licence in 2008 to broadcast local and national services to Somerset, and began transmission in 2014. The MuxCo Somerset multiplex is also receivable in South East Wales (Cardiff & The Vale). Output Radio Analogue Kiss 101 is a strong directional beam towards South Wales and the Brecon Beacons. Digital South East Wales digital radio is broadcast as the Mendip site is well placed to provide coverage to the area and the coastline of Wales.
