Iona Price: Dont worry, there is a fault causing loss of transmission from Cwm Twrch and Ystalyfera. The BBC are aware that service was lost at 00.56, but no time is shown for expected resumption of service.

Kerry Beck:

It is operated by Arqiva and is nothing to do with this independent website that offers reception advice.
