Which companies have run the Channel 3 services in the Llanddona transmitter area
Not quite sure why you've posted on the Caernarfon transmitter page, it's a very very low power relay, miles from you and your postcode is not predicted to get any signals from it. You are predicted to get good signals from the Trefor relay.
By the way, this is an independent technical helpsite, we are not the broadcasters or transmitter engineering.
If you are getting signals from Trefor, your aerial should be pointing fractionally west of NW (bearing 307 degrees) with its rods (or squashed Xs) vertical. There is also predicted good signals from Preseli however they may be more subject to changes in some weather conditions, a reliable local aerial installer may know (the aerial would be pointing fractionally west of due S). There's also predicted reception from Blaenplwyf but those signals would be poor/variable/or none depending on multiplex (groups of channels).
None of the transmitters mentioned have had/got any reported faults recently that I can find. With the recent weather conditions it's possible Trefor may have suffered brief power outages.
I would check with your neighbours if they are receiving Freeview OK because there's a possibility the weather may have done damage to your aerial installation.
I would check that your aerial seems intact and pointing in the correct direction and that your downlead looks undamaged (especially if it is old). Also check all your coax plugs, connections, flyleads etc, especially if you've changed anything in your installation recently, unplug connectors check for corrosion or other problems and reconnect them. Flyleads are a common problem, try swapping/changing them. See what signal strengths and quality you are getting for the multiplexes (groups of channels) shown in your TV's tuning section.
The correct UHF channel tuning for Trefor is C32, C34, C35 (C means channel) for the 3 PSB multiplexes.
If you have changed anything in your setup, make sure you don't have any HDMI leads near unscreened/poorly screened flyleads/aerial leads as HDMI has been known to cause interference.
