The Mendip transmitter is listed for Planned Engineering this week with "Possible Pixelation or flickering on some or all channels", so this is most likely what you've been experiencing.
You didn't say which news channel, but the other news channels aren't carried on the same multiplexes (groups of channels) so may not be affected at the same time.

UHF channels 35 & 55 are splitting into wide horizontal bars. The TV program is still there - just split into bands. Other programs other channels are OK. The aerial is in the loft and points towards Bristol. I think I'm off the Mendip transmitter. There is no booster. NP26 5WA Sudbrook (Caldicot).

Peter Robinson:

Is your receptionOK now?
I can only assume that is could have been some "passing" interference as the BBC are normally very good at reporting any problems that affect their channels and I can't find any reports affecting BBC channels on the BBCB HD / PSB3 multiplex on C35 from Mendip, or COM7 HD on C55.

I am currently having no problems either and I'm a bit further away than you. Your aerial pointing rowards Bristol is abour right, it should be compass bearing 171 degrees, that's 9 degrees E of due S at your locale.
You are predicted to to get excellent reception of all multiplexes from Mendip (and also Wenvoe!).

Surely viewers living in the drop out zones should receive a TV License rebate? Improving transmission would be one of the cheapest ways to level up society in 2022.

B Fair: What do you mean by dropout zones? The TV Licence is not a subscription, it only funds the BBC and S4C who make their channels available as widely as possible, i.e. every national BBC channel is broadcast from all 1,100+ transmitters, S4C is broadcast from every transmitter in Wales, BBC Scotland & BBC Alba are broadcast from every transmitter in Scotland, as well as all BBC regions being available on satellite and iPlayer. Viewers in Freeview Lite areas who don't have satellite or cable are still receiving all the channels funded by the licence fee, the commercial channels that aren't available in those areas don't receive a penny of licence fee funding.

B Fair:

If you have been experiencing some breaks in your signals in the last couple of weeks it's because Mendip is currently listed for Planned Engineering with Possible effect on TV reception "Pixelation or flickering on some or all channels".
If it's been going on for longer than that (continuously) please provide a full postcode and we can check your predicted reception. Other than that you may of course have some sort of fault on your aerial installation or cabling, check all your coax connections behind your TV.

I see Mendip is still listed for Planned Engineering, but information on Engineering work isn't automatically coming up on Transmitter pages.

Having problems with Channel 50. I have tried everything to try and get this Channel to work. No other channels are affected. It keeps coming up as no signal. Have checked the aerial, have tried re-tuning, have tried the lot and still nothing. Strange how no other channels are affected.

Melita Davis:

Hi, you say no other channels are affected, 50 (LCN50) is carried on the Local multiplex, do you get the following (also on the Local multiplex) -
LCN7 Bristol TV, LCN52 GREAT! movies classic, LCN61 GREAT! movies +1, LCN68 RealityXtra, LCN207 Tiny Pop ?

If you are not getting any of them then you are not receiving the Local multiplex.
If you are getting any of them, it's possible that LCN50 may actually be in the 800s and your sets memory needs clearing, so unplug the aerial and do an automatic full retune. No channels should be found and this should clear memory.
Plug the aerial back in and do a retune. Hopefully all channels will be correctly restored.
