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.

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.

The transmitter isn't currently listed for Planned Engineering, nor has it been recently and there don't appear to be any faults listed. As far as I can tell it's operating normally.
As you haven't given a full postcode, I can't check your normal predicted reception which may be marginal in your location under adverse weather conditions, also depending on aerial location.
Your problems with reception are most likely due to current weather conditions causing some "Tropospheric Ducting" resulting in Interference coming from distant transmitters (in Europe or the UK) which is currently affecting some parts of the south and southwest.

i continue to get very variable reception at WR5 2HZ no 10. It is in the green area for Mendip.
Is there a good reason why COM7 ARQB and SDN are so unreliable. They appear to be broadcast at the same power as BBC and D3+4 which are fine. The aerial is mounted on the lefthand side of house at a height which I believe is the optimum to avoid the trees in the direction of the aerial. Thank you

Paul Jennings: COM7 closed at the end of June, perhaps you mean COM5/ArqA? You're 109km away from Mendip and your postcode is predicted to get better reception of the COM4/5/6 multiplexes and similar reception of the PSB1/2/3 muxes from Malvern (only 11km away approximately to the south-west of you) so it may be worth considering having your aerial turned towards Malvern and rotated from horizontal to vertical polarity, or perhaps fit a new wideband type which will perform better on the lower frequencies used for COM4/5 if you're currently using an older grouped aerial (Mendip was historically Group C/D which only covered the higher frequencies of the UHF band).
