I can't find and current or recent faults listed for and there's no current Planned listed.

If there was a Wenvoe fault there would be many posts about it, so this suggests a problem with your own installation.

Have you checked the connections behind your TV? Have you changed anything in your setup at all?

I would check that your 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, unplug connectors check for corrosion or other problems and reconnect them. Flyleads are a common problem, try swapping/changing them. See what strengths and you are getting for the multiplexes (groups of ) shown in your TV's tuning section, that information may indicate issues with your aerial or downlead or possibly any distribution amp/splitter you may have.
Problematic connections, water ingress etc. can seem to affect of just an individual or several multiplexes.

Derek Matravers:

Do you currently have "" on UHF or is it just not tuned - maybe you did a retune when you lost signal (may have been weather conditions a couple of weeks ago) and this cleared the tuning?
Try a Manual tune on UHF C55.

Unfortunately we have those "weather conditions" again right now - Temperature Inversion/Tropospheric Ducting affecting large parts of the UK and disrupting signal for some, so you may have to try that manual retune several times.

I would check that your seems intact and pointing in the correct direction and that your downlead looks undamaged (especially if it is old) and is secure and not flapping in the wind.

Also check all your coax plugs, connections, flyleads etc, 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 you are getting for the multiplexes (groups of ) shown in your TV's tuning section, that information may indicate issues with your aerial or downlead or possibly any distribution amp/splitter you may have..

Problematic connections, water ingress etc. can seem to affect of just AN individual, or several multiplexes.

There are currently or recently no reported faults at , there would be a lot more people posting if there was.

Bernard Tyson: '/

No faults are being reported at that I can find and it's not currently listed for Planned .
(LCN11) is carried on the ArqA .
See https://www.freeview.co.uk/corporate/platform-management/channel-listings-industry-professionals for which channels are carried on which multiplex (groups of channels).
Are you missing any other ArqA channels at all?

It would be worth checking in your TV tuning section that you are correctly tuned to Wenvoe's UHF channels.
When Freeview juggled a lot of channels LCNs towards the end of January and you probably retuned, Wenvoe was listed for Planned Engineering and there may have been weak signals at the time you retuned and some multiplexes may have inadvertently tuned to another - there are several you could up at your locale.

The UHF channels for Wenvoe are , , , , , , , that's in the multiplex order BBCA/PSB1, D3&4/PSB2, BBCB HD/PSB3, SDN/COM4, ArqA/COM5, ArqB/COM6, COM7, Local.
(C means UHF channel).

If you are correctly tuned and still have a problem, I would check that your seems intact and pointing in the correct direction (bearing 227 degrees, pretty much SW for your locale) with the rods (or squashed Xs) horizontal, and that your downlead looks undamaged (especially if it is old) and is secure and not flapping in the wind.

Also check all your coax plugs, connections, flyleads etc, unplug connectors check for corrosion or other problems and reconnect them. Flyleads are a common problem, try swapping/changing them. See what Strengths and (or Error/BER) figures you are getting for the multiplexes (groups of channels) shown in your TV's tuning section, that information may indicate issues with your aerial or downlead or possibly any distribution amp/splitter you may have.

Problematic connections, water ingress etc. can seem to affect of just an individual or several multiplexes.
