Hmm. Putting your postcode into the DigitakUK checker About us | Freeview shows that predicted reception from Kilvey Hill at your location is likely to be variable to poor! (Try it yourself).
Are you able to receive the COMs 4/5 & 6 multiplexes from Kilvey Hill, or could you get them before the retune event?
See Channel listings | Freeview for the channels on those multiplexes if you aren't sure.

The strange thing is that you are 2km from the Pontardawe transmitter which is line-of-sight but there's no predicted coverage from it according to DigitalUK !! But it's not radiating much signal in your direction, and it was off-air briefly this morning.

I'm wondering if when you retuned, you ended up tuned to the wrong UHF channels which won't help.

You need to enter your TV's tuning section and see which UHF channels you are actually tuned to.
For Kilvey Hill it's 21, 24, 27, for the PSB1/BBCA, PSB2/D3&4, PSB3/BBCB HD multiplexes and 25, 22, & 28 for the COMs 4,5 & 6 multiplexes.
For Pontardawe its 33, 36, 48 only as it doesn't have the COM muxes.
(Note aerial rods should be vertical for these two transmitters).

Kilvey Hill will give you the best choice for the Welsh region IF you can get the COM muxes. Otherwise predicted reception from Carmel is better (for the Welsh region) for the 3 PSB muxes (although the aerial rods need to be horizontal). You probably wouldn't get the COMs from Carmel because of interference from Pontardawe which uses the same UHF channels !!
It may pay you to get someone who is very familiar with reception in your area to look at you aerial installation to see which transmitter may give you the most stable reception.

Otherwise the other possible option is to consider going Freesat - a lot of modern TVs have built-in Sat tuners so you only need a Dish and LNB.

Alun Short:

Could you please be a bit more precise about your installation? I'm getting the impression that you have several TVs with each TV having its own aerial. On the other hand you may have one aerial with a splitter (maybe combined with a booster) giving a separate output for each TV.

Does another TV work OK plugged in the place of the TV you are having problems with?
Does the TV you are having problems with work in one of the other places where another TV works?

gareth williams:

There is Planned Engineering at Kilvey Hill this week with "Possible service interruptions".
If you retuned earlier whilst the transmitter was off-air, it will have cleared all your previous tuning.
Repeat a retune, by now the transmitter may be back on air, but there could be further interuptions tomorrow.

Since they people responsible for the "freq" change I've found that i either have lost channels or have to mover around my home to watch some stations. I have two digital Ariel's both have booster boxes. If / when I can get more then six stations the all seem to break up around 18:00 hrs. Some days I can't even get one station.
If you have / give me an asnwer, please DON'T use Techno Babble.

This is an independent help site and we can certainly try to help you with your reception problems, but we do need a full postcode to look at the predicted reception at your location.
It'd be helpful if you could say which way your aerials are pointing (rough compass bearing) and whether the rods on the aerial are horizontal or vertical.

Reception on the Gower peninsular is appalling - only the main BBC channels are reliable.
This is not a temporary weather issue, it has been true for 6 months.
Transmitter power has been reduced and reduced. Its now a postcode lottery.

Dave Jones: The output power has not been reduced at any transmitter, except for short periods of time during planned engineering works or due to a fault, and certainly not lasting for several months. It's far more likely that there is a fault in your aerial system somewhere, perhaps some bad weather over the winter has damaged it. Start by checking for any loose or damaged cables or connections behind your TV, then follow the cable as far as you can safely access back towards the aerial.
