Chris, I agree! My issues are, simplified:
1. Auto-retuning of my "smart" TV to unwanted Carmel. I plan to replace the old wideband log-periodic with
a Blake Group-A aerial modified with a larger mesh reflector to supress Carmel (north)
in favour of wanted Huntshaw (south) That will, hopefully, "outsmart" the TV :-)
2. Complexity of registering for, and selecting, streaming options. Why must we register?
All online services want too much personal data. This is unjustifiably intrusive -
and increases online vulnerability !
3. Longterm, obscure plans. Fibre or 5G are unrealistic for many, particularly in rural areas.
As you say, this will probably get bogged down for years to come!

1) Sounds like a plan. I did wonder about you wanting Carmel :o but I didn't looked back to see if you've previously said which way your aerial is pointing as I couldn't remember. Yes that must be irritating if auto retunes get Carmel, doesn't the set have a setting for Region or Postcode? And nowhere to turn off auto-updating?
My LG nearly 7 yrs old now, will sort of auto-update a mux if I select another channel on the mux which is irritating if they've been swapping things about on the COMs depending on which mux is watched first, the new/additional/replacement can end up in the 800s which results in me having to manual retune or edit!
2) Yeah, too many things wanting too much personal info these days, they get the absolute minimum from me and not always 100%.

Michael: Having reviewed your earlier postings, it looks like you may be in Ilfracombe. If you are still at the same postcode, then the Freeview predictor does not even mention Huntshaw Cross as a possibility, not even very poor.
You said previously about the co-channel interference to users of the Ilfracombe relay, caused by Carmel, and which varies by the tide. The ERP of the Ilfracombe relay is -4dB with respect to the former analogue, meaning there was an effective doubling of power at digital switchover, and maybe this was done in effort to compensate the co-channel interference from Carmel.
At 700MHz Clearance on 19/06/19 the Chambercombe relay became co-channel with Huntshaw Cross' COMs. So those in the vicinity with a Huntshaw Cross aerial will have found their COM reception wiped out by the relay! The predictor suggests the Chambercombe relay may be available at your postcode. If this is still where you are, do you get good reception of the Huntshaw Cross COMs?
There are clearly a lot of transmitters whose signal reaches the Ilfracombe area, whether strong enough to be watchable or not strong enough to watch but enough to interfere with another, desired transmitter. Judging by the predictor, there may be four six-mux transmitters in Wales to contend with, filling 21 channels. Post 700MHz Clearance there are only 26 channels left for TV.
The situation is brought about by the fact that the water is flat and without hills which would otherwise act to block unwanted, distant signals, but, further, the tide rubs in the salt by changing over time what's coming over. The other aspect is that the local terrain drops downwards to the water preventing or making difficult reception from a main station, thereby necessitating the presence of relays which require three channels.

There are, of course, 27 channels available for TV post-700MHz Clearance, not 26 as I said. I made it to be 26 by subtracting 21 from 48, then subtracting 1 (to account for C38 not being used).

Yes, he is near Ilfracombe, and I'm pretty sure he already knows most of what you've said ;)
There are several locations along that general costal area that have problems with some transmitters in Wales, one I recall is Carhampton co-channel with Kilvey Hill even the same polarisation!!

Hi all!
Thanks for your postings. As Chris says, I am kinda savvy :-) West of Ilfracombe at 125m elevation; clear view of Swansea. Licenced radio amateur. Degree in computing. Bucketfulls of DTT experience with aerials and interference... We had a local self-help relay, managed by me; discontinued when Carmel switched to our Ilfracombe channels, obliterating it as our feeder. Even before DTT, as the Bristol Channel tide rose and fell,
I had to manually switch between Preseli and Carmel. We had a local self-help relay, managed by me; discontinued when Carmel switched to our Ilfracombe channels. Our ante-deluvian TV obediently stuck with the channels I assigned, initially Preseli and Carmel, later to Huntshaw. Now upgraded (???) to "smart", our TV knows better - and frequently auto-retunes from Huntshaw to Carmel when the tide temporarily delivers a stronger signal and demotes Huntshaw to the 800s (no always the same one). Curent plan-A : install a Group-A yagi with a more efficient mesh reflector. Plan B : dunno. Perchance persuade the XYL that a second dish for 28E might be acceptable after all. My existing ground-mounted dish is on 19E.

Since the problems with this transmitter on 13/06/24 I have had interference and pixelation on BBC1 and BBC2. I have not had this problem before and the other channels are ok. Can you repair this fault please? Thanks

The Carmel transmitter was listed at the beginning of the week for Planned Engineering -
Carmel transmitter: Possible effect on TV reception week commencing 10/06/2024 Pixelation or flickering on some or all channels [DUK].
The work may be continuing and this MAY be the cause of your problem but we need a full postcode to check your predicted reception and check for possible interference.
Have you at anytime whilst you had Pixelation or No signal tried to retune?
If so, please advise, and do NOT try to do so in the interim.
