Yes it's annoying. I've used my Channel manager to move my HD channels to 1, 2, 4, 5 but not ITV as it hasn't yet implemented full local regional news - still only 4 main regions (+ STV, UTV & ITV Wales). I've put the SD ones in the 900s so any (manual) retunes don't mess things up.
It's also irritating that doing a basic search I can't quickly find the BBC web pages that covered the changes, there were some but I don't recall where they were. One shouldn't have to rely on other independent websites for the information (and sometimes there can be errors or misinterpretations)!

Annoyingly my TV doesn't have an option to move the channels. The edit channels screen only has the options to lock and delete a channel. Has 'rename' as an option but even that is greyed out

My set doesn't have the option direct (not a Samsung) I have to renumber.
I renumber the SD ones first to clear the LCNs.
So I did 1 to 901, 2 to 902, 4 to 904, 5 to 905, 9 to 909.
Then 101 to 1, 102 to 2, 104 to 4, 105 to 5, 106 to 9. I also did 107 to 8 as 8 is clear - my Local station is on 7, also 23 is too much hassle (2 key presses :o )
PS. Posts sometimes take a while to appear, so wait a minute or two to avoid a double post.

Unfortunately my model doesn't have an option to renumber the channels either :(

Hello. Having interference on Channel 37 from the Oxford transmitter for the last few days. The other 5 muxes are ok. Wondering if this is just me or if anyone else has had issues? If I check the signal via the menu I'm getting a pretty solid 100% quality and 72% strength (about normal for my setup) BUT the the quality reading is blipping every 10 seconds or so down to 70%, even as far as 30%. I suppose that is the issue but I've not had it before. I haven't changed anything in my setup hence asking on here. Thanks for any replies.

Hi Stu. You may have noticed 3 posts before yours that the Oxford transmitter is having Planned Engineering, so that may not be helping the situation as IIRC you are not in the best of locations for reception.
However, that said, the fact that is blipping up and down is a touch odd. Now, there is some very marginal "Tropo" just passing affecting parts of central England, but that should be gone by the end of the day, whether that is contributing to the issues is difficult to say.
Put your full postcode into https://restoretv.uk/post…ure/ if it says Yes, even if you haven't had a postcard from them get in touch with them and request a free filter (0800-1313-800). It could be a new/upgraded phone mast now giving problems.
I assume you've checked your aerial is still pointing correctly, coax ok etc. If you still get sufficient strength with the amp/splitter out of circuit, see if the quality then remains stable. If so, it could still be interference causing the problem and now it's not getting amplified it's not having the same effect., and so hopefully a filter (before the amp/splitter) may cure the issue if it's not the engineering/weather.

Thanks for taking the time to reply Chris.
Had noticed the engineering works and I do know that living south of Cirencester is getting towards the edge of coverage. This is out of the ordinary hence the question really. Could be the atmospheric conditions I guess. Will have to give it a few more days and see if it improves. Didn't know the atmosphere was causing problems again! Where do you find out about the current conditions?
I agree with you - the blipping up and down seems odd and the fact it is only on one mux seems odder still.
I have got a filter (well a distribution amp with a filter included).
My aerial is overdue a check and possible upgrade but normally I get all 6 muxes well enough that there's no interference. Cables are mostly double-screened but there's a few metres of what is probably old single-shielded cable from the aerial to the loft amp (the distribution one mentioned earlier). I know that's not ideal.
Will give it a few days and see if it changes.
Many thanks for your time.

Hi again. How old is your amp/spliiter?
Unless it's very new, the chances are that the filter in it, is what is often termed a 4G/LTE filter for 800MHz. The spec. for it should tell you.
These days you need what's often called a 5G/700MHz filter (sometimes LTE is also mentioned) but 700MHz is the important bit. Such filters will also clobber the 800MHz issue.
If that postcode check for restoretv said YES you should definitely get one.
I didn't think there was any "Tropo" this week but did a precautionary check, it's so marginal and only predicted today over a relatively small area, I'd be surprised if it was having much if any effect except in a few isolated cases. Such things are "predictions" and I wouldn't take it as gospel.
See if things are more stable tomorrow.
