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.

I live at postcode CF320PJ (Ogmore by sea) and have always received a good signal from the Kilvay Hill transmitter (my arial is obviously pointed at this transmitter) Recently, after getting interferance, I retuned the TVs but now find that I am receiving BBC south west not wales. Any ideas welcome

Carl Lewis:
You should never retune when you have interference or loss of signal due to that, or Planned Engineering or transmitter faults that cause pixellation or no signal. In most instances this just clears the correct tuning of the affected multiplexes and you end up with nothing or tuned to the wrong (more distant) transmitter.
If you are correctly tuned, do NOT retune it serves no purpose.
The only instance where a retune may be suggested (usually advised by an on-screen pop-up) is where a commercial operator changes one of their channels on one of the COM multiplexes. If you happen to be in an "awkward" reception area then a manual retune on the UHF channel(s) for the affected multiplex(es) is usually the best suggestion.
Your predicted reception at your locale is not the best, although it could depend on where you are within your postcode as it could be variable, even poor or good! for some multiplexes.
This is because you might receive signals from other more distant transmitters (and there are several in parts of Devon, Cornwall, also parts of S.Wales) that use the same frequencies and in normal conditions it wouldn't be a problem. Matters will be made worse in weather conditions that enable the TV signals to travel a lot further than normal - we have had such conditions of late. When there is very strong "Tropospheric Ducting" even signals from Europe can be received (see How does good weather affect my television? | Help receiving TV and radio and the links on those pages for a simplistic explanation). Not all multiplexes will be affected at the same time or for the same lengths of time. A lot of aerials have "side-lobes" which can receive signals from directions other than the one the aerial is pointing.
Checking that your aerial is intact with no missing elements, is pointing in the correct direction (bearing 314 degrees - NW at your locale) with the rods (or squashed Xs) vertical.
The best thing to do will be to do a Manual retune for Kilvey Hill as follows - first, unplug the aerial and do a full automatic retune. This should clear all previous (and incorrect) tuning.
Plug the aerial back in, and in the TV's tuning section, do a manual for each UHF channel -
For Kilvey Hill it's C21, C24, C27, for the PSB1/BBCA, PSB2/D3&4, PSB3/BBCB HD multiplexes and C25, C22, & C28 for the COM4/SDN, COM5/ArqA & COM6/ArqB multiplexes, also C34 for the Local (Swansea) multiplex.
(C means UHF channel).
You may have to repeat that procedure a few times whilst/if interfering conditions persist over the weekend which some predictions suggest.

Susan Rees :
Apart from the Planned Engineering which will not help (and they never provide details of the work or duration) I'm afraid it's down to current weather conditions -
They have been causing Tropospheric Ducting affecting much of the south coast and southern parts of the country on Saturday and now extending into the Midlands and North of the country through Sunday including East Anglia, now currently affecting Wales and England. This causes interfering signals from distant transmitters in Europe or the UK to affect reception of your wanted signals. This can periodically last, seconds, minutes and sometimes much longer - Do NOT Retune.
There is nothing you can do about this apart from wait for conditions to change, or use online streaming if available.
IF you did retune, you'd be best manually retuning the UHF channels for your transmitter, as detailed in the top section of this page.
