Sony moved True Entertainment and some of their other channels to Local multiplexes, see Digital UK | Channel listings . In your location you should be able to get that along with the local Bristol TV channel on LCN 7 see Coverage Checker - Detailed View . If you haven't got that eithe,r you may not be receiving the Local multiplex on UHF30. Have you got a wideband/Group T orr Group K aerial? If you have an old group C/D aerial this may be why you are not getting it. As long as you don't have Cable or Satellite you can get free help with a new aerial, ring the Freeview Advice line 0808-100-0288 see Important changes to Freeview TV signals | Freeview also see the FAQs on that page in case they may help.

If you are talking Freeview - those channels were moved by Sony to local multiplexes, see Digital UK | Channel listings If you receive the Manchester local multiplex then maybe you just need to retune. do this by unplugging the aerial and doing an automatic tune to clear all previous channels then plug the aerial back in and do the same again.
If you are not in the Manchester area, and also don't get a local channel on LCN7, then you won't get those and some other channels that are on local multiplexes.

I'm not sure that the radiation pattern has been changed recently. In any event that will be taken into account by the coverage checker. Because of the 700Mhz clearance see Digital UK | 700MHz clearance and the number of transmitters using a smaller number of UHF channels, then this will affect reception of some channels from some transmitters in some locations but again this will be taken into account by the coverage checker, maybe you need to enter your house number to get a more accurate prediction.
It's also possible you might have some very local issues affecting reception - a tall building, trees, nearby water tanks or solar panels, other nearby metal objects etc can all affect reception of signals.
Although it could depend on which Wideband aerial you've got, generally the Group K will have better gain at the low end of the UHF channels.
If you enable Pro Mode by the coverage map at the top of the page, you should be able to look at the pattern for each multiplex (click in the list), but again, as already mentioned this should be taken into account by the coverage checker.
If you have any devices with RF outputs, I would set them above UHF56.

That is deplorable. This is not the first time that I've heard of cases of people with issues since the Mendip retune not getting the aerial help they should have. I suggest you ring them 0808-100-0288 request/demand if necessary to speak to a manager and ask what they are going to do after failing to comply with their obligations and at the very least get a written admission and apology.

Quote "Those figures are only for guidance"
Precisely. So why, when the guidance for another transmitter is not as good as the one they are currently using, would anyone want to suggest or recommend that someone go the the trouble, inconvenience and probable expensive of making a change that is unlikely to result in any improvement! I find your remarks bizarre to say the least.
And of course I know that they don't take account of very local variables, and unless you know the precise location and maybe have done measurements, you certainly won't know if another transmitter will produce a better result when predictions indicate otherwise. You seem to think that you are the only one with more than 50 years experience as an engineer, and I'm getting a little fed up of some of your lectures as if I know nothing. If I make an error, fine, correct me, but stop trying to make out I'm ignorant.

You'd best ask the BBC, they're unlikely to see your comments here ;)

The only assumption I made was it's probably the digital cliff edge, some of the reasons for which may in part be addressed by the questions posed by nobody.

Your partial postcode doesn't indicate which transmitter you may be receiving. A full postcode is needed to give any more constructive comment. There maybe several transmitters receivable at your location and if you are tuned to the "wrong one" and so the signal may be marginal which could possibly lead to this sort of issue.

Some people having similar issues receiving Saorview and Freeview are wondering if they are now suffering 4G interference since recent channel changes.

According to Gold's website "If you have an older DAB radio (without the DAB plus feature) you may not be able to find us and you will need to purchase one of the latest digital radio's with the DAB+ logo. "
It seems they have changed recently, according to Wikipedia "In September 2019, many of the local-level DAB transmissions of Gold were turned over to the new service Smooth Country, requiring listeners in affected areas to migrate to the national DAB+ transmission of Gold. Gold continues to broadcast on DAB in the East Midlands, where Smooth Country took the place of Chill."
The DAB+ broadcasts are on the Digital One national multiplex. If you have a DAB+ radio it may be that you need to reposition your radio or aerial if in range of a transmitter. It seems that the DAB transmissions only continue on the Nottingham/Derby/Leicester DAB transmitters.
