Hi @CTxCB @Colorado,
Adding media sources to the game is my domain. We signed an agreement with the BBC last year but looking at the list, Radio Wales was not included in that. As such, this is why it's not currently appearing for those leagues and teams.
I'll reach out to see if it's possible to get them added for FM23. If there are any other media outlets you'd like to see included in the future, drop me a DM on the forums as I'm all ears.
All the best,
Andrew
