G.pugh: Presumably it will come back on once the fault listed in the engineering post above yours has been fixed. This is an independent technical help website, we don't have any more information on faults or engineering work than what is already publicly available.

G.pugh:
Apart from Mynydd Machen, which is now line-fed rather than a relay of Wenvoe, two other transmitters which are relays via Mynydd Machen, are off-air, Wattsville and Pennar.
I suspect with the atrocious winds there have been there'll be a power cut somewhere that's causing this.
The BBC are still reporting them as off-air, but the reports may not yet have been updated and you may have your signals back. If not, do NOT retune as it'll likely just clear your correct tuning.
