Francis Heron:
Towards the end of last week, there was some "Tropospheric Propagation" that sometimes comes with high pressure (less common at this time of year, more frequent in summer) - this causes signals to travel further and so distant transmitters in he UK & Europe can interfere with our own signals.
If your set is setup to "auto-update" if it "sees" any transmitter changes, then it could have tuned itself to signals it no longer can get!
I'd suggest you unplug the aerial and do an automatic retune. This should clear all previous tuning as no channels will be found. Plug the aerial back in and repeat the retune and this should restore all your channels correctly.
If this doesn't work, post back with a few more details about your installation, how old your aerial is, do you have any (amplified) splitters etc., have you made any changes recently? There have been no changes at Emley Moor since the retune event on the 5th February which I assume you carried out. There were no power changes involved with that event.

As per several recent posts on the Emley Moor transmitter page, the listings at the top of the page are wrong. The site owner has not had time to update all the changes resulting from 700MHz Clearance.
In particular please refer to my post Wednesday 5 February 2020 7:48PM on p217 over there.
I have repeated that in several posts recently.
I did suggest you do a Manual tune for the Sheffield muxes as you seem to be picking up some strong signals from Emley. Same would apply for Emley muxes if you want Emley.

If you don't want clear and precise information from independent experts, why come here asking questions in the first place? The information you have got from Freeview is exactly what I've posted here in several recent posts!

Not certain where you are getting C35 from, but it is not transmitted from Sandy Heath.
Sandy Heaths channels are C27, C24, C21, C33, C36, C48, C55, C56 in the order PSBs1-3, COMs4-8.
If C35 is as I suspect a Local multiplex from Cambridge from the Madingley Light transmitter, then you are doing quite well to pick it up. There was a slight power increase on that Local multiplex last week, but it is still low power at 3.2kW.

Well you'll be pleased to know that these are the last of the currently planned retune events for UHF channel moves.
The only retune events you (probably) may have in future is where a broadcaster moves a programme channel from one multiplex to another, or it's replaced by something else. Some sets will do those automatically.

This listings around this site aren't necessarily up-to-date. With all the transmitter changes as a result of the 700MHz clearance, the site owner has not had time to update everything. Whilst the list of channels in "change over time" table here are correct apart from "_local" which doesn't exist, the date is wrong, as are the channel numbers in the top section. Hopefully the site owner will update them at some point, but it's a laborious manual task!

The following post has been copied from the Chesterfield transmitter page.
"I'm a Local TV Aerial Installer and have noticed since the Retune event on the 5th that in certain areas in Dronfield the CBER readings on CH37 (ITV mux) are very bad and on the edge of Pixellation. I have reported this to Freeview.
Regards
Darren."
Also note that at the present time, the site owner has not had the chance to update the list of channels here -
From the 5th Feb.2020 the channels are C39, C42, C45 in the order PSBs 1-3.

Thanks for your info., good luck with getting Freeview to take any notice, many have tried to report various faults to them in the past, but their front facing staff only seem to be able to tell people how to retune and they don't know the difference between "Tropospheric Ducting" and High pressure!
I have copied your post onto the the Dronfield transmitter page as well.
Also note that at the present time, the site owner has not had the chance to update the list of channels here -
From the 5th Feb.2020 the channels are C31, C37, C29, C43, C46, C40 in the order PSBs 1-3, COMs 4-6.

Just to be crystal clear, when I talk about too much signal, I'm talking about what is getting to the set(s), NOT what is being picked up at the aerial.
