Swansea Sound is an independent local radio station broadcasting to Swansea and surrounding areas, aimed at a core 40+ demographic. The station, launched in 1974 as the first of its kind in Wales, is owned and operated by UTV Radio alongside its sister station, 96.4 The Wave.
Swansea Sound began broadcasting on 30 September 1974 as the first commercial radio station in Wales, and the first commercial radio station to broadcast bilingually in the English and Welsh languages. Originally, the station broadcast on 1170 AM and 95.1 FM before moving its FM frequency to 96.4 in the early 1980s.
In 1995, the station was split into two separate services - a practice that had been widely adopted within the commercial radio industry in order to avoid relinquishing frequencies - with a new station called 96.4 FM Sound Wave (now 96.4 The Wave) launched on the FM frequency, while Swansea Sound continued to broadcast as normal on 1170 AM.
The station can also be heard on DAB Digital Radio across Swansea & South West Wales, although its medium wave signal can be heard beyond the official transmission area in North Devon and across the Bristol Channel. The transmitter is located Winch Wen, on the side of Kilvey Hill and for technical reasons does not use the same mast on the top of Kilvey Hill as its sister station.
The majority of Swansea Sound's output is produced and broadcast locally from the station's studios in Gowerton (shared with The Wave 96.4 FM). The station also carries UTV Radio's networked show Late Night Love, which is broadcast from the studios of Signal One in Stoke-on-Trent, six nights a week.
Alongside music-led daytime programming, Swansea Sound also airs Welsh language output in the evenings including hourly news bulletins, music and talk. The station also provides live commentary of all Swansea City A.F.C. football matches. Specialist programming includes weekly country music & religious shows and a Sunday morning-phone in.
