When the Shortwave band is closed or there are no active stations, I often scour the internet for new stations to add to my saved list on the Denon Network Player. I came across a new station the other day and have been listening to it since.
It is a former independent commercial radio station called "Celtica Radio". This station has an interesting history: http://www.celticaradio.com/aboutus.html and a long list of experienced presenters. As I understand it, Celtica plays only music from established and new artists that is out of the jurisdiction of the Performing Rights Society, or Phonographic Performance Ltd.
Have a listen and see whether you agree with my assessment: It is a professional sounding station with an obvious UK sound, but with a definite Welsh flavour. You can find links to listen here: http://www.celticaradio.com/index.html
Many UK stations on the air do not succeed in sounding like they are in any way local, being the output of large commercial enterprises. Celtica sounds to me like a station that would deliver that elusive local feel to the target audience in Bridgend and Wales in general.
