OK seem like I spoke too soon,,,, I seem to be missing COM4 ie ITV 3 etc..
I didn't notice before as I don't really watch anything on that much.
What I think I will try is to see if I can can connect in the old aerial and selectively tune in that mux with both connected. I think I had two connect aerial working together before.
Also my PVR missed the BBC mux at the very least
So its not all sorted yet,

Fiddled with the old aerial to try and get the missing mux but ended up losing the lot lol.
Back on nottingham on my normal aerial, Sky news is fine atm, however there is a mux with poor/no reception it is the ITV3 one I was hoping to pull in so it is poor on both aerials it seems.
However I have sky back on my main aerial, i could pretty much watch that 24/7 and often do so I am pretty happy, just had a tiny bot of noise on sky.
I am in the unfortunate position that the i am pretty much in a straight lline between the two transmitters.
Maybe if I tilt my aerial to 45 degrees and take the reflector off I can pick up both at the same time lol.
Might have a go at building that log periodic for a laugh :)

Made a new connector for the old aerial pointed it at waltham retuned seem to have pretty
much every thing 140 channel on my HD freeview recorder. Might be missing some local mux
but it might be off air.
Seems to be best ever I have channel 10 mux (itv3 ) which was previously missing.
Results :-
m1 95% 0 bit error psb1 c49
m2 92% 0 bit error psb2 c54
m3 hd psb3 c58 (on HD recorder signal strength 90% signal quality 79) BER 0 (bit error rate?)
m4 93% 0 bit error (itv3) com4 c29
m5 90%% 0 bit error (11 pick) com5 c56
m6 92% 50~100 bit error (18 4 music) com6 c57
lng missing
m7 missing (HD?)

Well I am fine on Waltham tramsmitter, I have every channel without noise.
I suspect if I switched back to nottingham I would get the same (will try later).
But I might as well stick with Waltham, it's easier to deal with I can just lay the aerial on top of the insulation
in the loft. Its much harder mounting a vertical.

Just an update, I have been fine on Walthan for a while now so I will be sticking with it.
I have not got round to retesting the Nottingham one, but I imagine the recent interference has gone now.
Waltham is still better than Nottingham was.
I was using Nottingham because I thought it was a stronger signal, however Waltham transmits at two different power levels, so they (wolfbane site) may have used the lower power to give the signal strength.
But in the final analysis I now get all the channel pretty much perfect, and that was never the case with Nottingham, I always had some problems on at least one mux, ableit a mux I rarely watched.

Interesting Daniel, I have been having interference problems recently which is one of the reasons I tried Waltham (i was on Nottingham as i live there)
The problems have clear up the last few days, but I wonder if that is just due to the weather and if the will return when it goes back to bad reception weather, which is presumable high pressure?
One other thing a new local channel for Nottingham went live today but I can't get it on waltham but I did get its test broadcasts when I was on Nottingham, however I am not too fussed about it, I might try reconnecting the aerial which points to notttngham to pick it up from there when I have some time to waste.

Anita: What sort of interference is it Anita? It could possible be 4G which are new transmissions for mobile phones which can interfere,
Is you aerial and outside the those or in the loft? Outside I assume.
The thing is I had a lot of problems with interference last week but they seem to have gone this week it might be they are trying to squeeze in these signal and have moved from my area to yours.
You can tell if it is 4G as the blocks tend to have a checked pattern inside them,

Just put your post code in. I might help if you gave the first 3 digits of your postcode so other can see what you get, the signal strength (Field dBV/m) is what you look at.
Here are the results for my postcode NG7

IT is interesting I could be getting a stronger signal from Sutton apparently!!!
I only recently started using Waltham as I was getting interference from my usual Nottingham tranmitter
I basically had similar problems to what you describe but that was a few days ago, they seem to have gone now though. But I ended up switching to Waltham as it is better for me, so I can't be sure if the problems I had on notttingham have gone as I have not re-tested.
My aerial is in the loft so I can play around with it.
I assume yours is outside so that limits your actions unless you call someone out.
Check what cabling you have, but basically that has not changed has it?
"but the tv wouldnt let me" I am not sure what that mean? Do you mean it could not pick the signal up?
When you do a scan if it can't find the signal you lose the whole mux. Ie the 'bunches' of channels listed above.

If you look at my previous recent posts (long rambling ones lol) you can see the problem I had with Nottingham.
Also Anita do you have a 4G filter? That might help, but probably not much if you are missing a mux.
It could be the rain affected you aerial and cabling.
I don't see other people reporting problems on Sutton here but them they didnt on Nottingham either.
If your aerial is outside I don't that there is much you can do yourself really.
As I said it could be they are trying to see where they can squeeze 4G transmissions in without causing interference, but that is guess work somewhat.
But it would help if we knew your expected signal strength, but then it used to be fine and the strength will not have changed so maybe not so much of a help really.

Anita this is the page for the Sutton Transmitter, note no one else is reporting problems there, but few know of this site and when I had probs on Nottingham no one else reported them there.
As you can see the BBC channels are all on the one 'mux', lose that and you lose the lot on BBC, however you won't lose them all untill you do a retune and it can't find the signal, then the signal will not be stored at all and it will not be found again until you do a retune and finds it.
If you do not retune it will still remember it but you will get poor reception or no picture, but as I say if you retune and it can't find it it will be lost from the channel listing untill a good retune.

lol I've been busy, was looking at a video on how to make a log periodic on youtube, interesting stuff.
Anyway I was still having problems. I believe it is due to interference from other stuff like mobile phone or police or other digital transmissions, sometime I can see a checked patten.
Anyway I connected my spare aerial and laid it on the loft insulation and pointed it in the general direction of waltham to see what the signal was like from there. It was connected up to my PC /TV monitor as I didn't want to have to retune my TV to avoid losing a signal.
Anyway when I got down stair was I was very surprised to see Sky TV displayed on my monitor!!
I was thinking how can that be? I have not retuned it yet!!
I Had a check and all the other channels were there too I was wondering if it had an inbuilt receiver.
Then I checked the signal frequencies and found they were indeed from Waltham.
So I really do not know what happened there, does it have some clever software inside to find the channels?
Did it remember an old tuning from before I bought it? It i have never tuned it to Waltham, unless somehow my initial tuning picked up waltham and magically avoided Nottingham. Rather baffling!!
It is possible it picked up the signal through the back of the aerial after it missed to nottingham Sky Tv muc totally
But my main TV is now tuned to Waltham and I have all the channels with not interference or problems.
So problem solved for me!!!
But my advice for anyone with problems from the Nottingham transmitter is to try Waltham, it worked for me even though it is supposed to be a weaker signal.
I have also discovered I can get all the channels on my DVB-T USB stick, I have never been able to do that before so I am over then money as I can easily record to my PC as opposed to my slows cumbersome PVR type thing.
So problem solved for me, indeed better than ever, from my experience I would suggest the Nottingham transmitter is best avoided. I can get Waltham in the loft on a basic aerial (albeit with a booster) so I expect most can, not tried without a booster yet.
