Moved the TV a bit and how I have good Sky on the TV and a worse one on the monitor/TV.
So it is all very fickle, it's like trying to get a good signal on a FM radio, a bit of a black art.
But right at this very moment I have a good clear picture on every channel, probably the best it has ever been!!!
Maybe a change in the weather occurred, it was raining, perhaps all the thunder has stopped?

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.

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.

The output power (ERP) of a transmitter largely determines the transmission distance, but obstructions between the transmitter and receiving aerial can seriously affect recption. Tall building, hills and mountains all have an effect.
Waltham has different ERP for the PSB muxes from those of the COM muxes, a common variation found at many full service transmitters. Lower power reduces the signal strength, I suspect you are equating 'strength' with 'robustness', which is not correct.
That you now have satisfactory reception from Waltham suggests you have elminated whatever was causing the problem.
A word of warning if you consider bringing the Nottingham transmitter back into your system, you can ruin your reception of all channels if you don't do the connection correctly. I would strongly recommend use of a UHF switch with two inputs and one output such as this at
Two Way F Plug Aerial Switch | Maplin (others are available), do *not* use a simple splitter/combiner as that will make signal reception much poorer! The F-type connectors are poften preferred nowadays and can be fitted to most good quality coaxial cable as used for UHF TV aerials or satellite LNB feeds.

Thanks Mike, I thoght they might have boosted the power on the higher frequency muxes as I believed those signals do not travel so well, however after a careful look one on the low frequency signals is also high powered so it is indeed as you say the PSB one which are boosted, presumably because public service broadcasts are considered more important, no least because you actually pay for them!
I have no need to connect the Nottingham transmitter now because I get all the muxes with no bit level errors apart form COM6 which has an error level of typically 80, however there are no visible problems on the picture,
the only way I knew there were any errors was by looking at the signal info. Furthermore I am pretty sure the reception on that mux is even worse on Nottingham!
I think in the past I have managed to connect two aerial successfully just by twisting the cores and shielding together. That was before I had a booster in the loft, I found I could pick up some signals on my external aerial ( which was not wide band) which I could not get on the loft aerial.
I seem to remember the tuning on that was rather tricky, I vaguely remember having to unplug the aerial at the right time to avoid picking up the wrong signal! (I don't think I had the ability to selectively tune specific channels) separately.
Also it is much better on Waltham as I can simply lay the aerial on the insulation and get all the muxes (the signal is horizontal unlike Nottingham whcih is horizontal). The Nottingham one is precariously mounted high in the loft, if it was as low as the Waltham one I would probably lose a few muxes, it is also rather obtrusive in my small loft so I plan on removing it completely.
I could get a better signal if I moved the Waltham aerial higher, but there is not point really as there would be no visible improvement and it would be obtrusive.
Note I combined the two aerials, I didn't switch between the two, and they were pointing at different tranmitters.
At one point I did try having both aerials pointing at the same transmitter to 'double' the signal strength but that was the failure a professional aerial fitter told me it would be!! ( I still gave it a go though lol). I thought if I got the cable lengths exactly the same it might work but it was completely hopeless, couldn't get anything at all.

Twisting cores and sheilding together is *not* the correct way to connect three pieces of coaxial cable together - the impedance mismatch causes horrendous problems. You say the tuning was rather tricky - I'm not surprised as the tuners will have been compromised by the grossly incorrect cable joins.
Pointing two aerials at the same transmitter does *not* double the signal strength, it could in fact ruin reception of several channels! Aerials and the cabling of them do not work the way you seem to think. As you found out eventually!
I strongly suggest you borrow a decent book from the Library about how RF system work with particular attention to impedance matching, standing waves and lead lengths.
