StevensOnln1, seems I made a mistake, it is com7 which is T2, com6 is indeed T1 and I do get that on my T1 TV receiver, it is com7 my TV will not pick up unsurprisingly as it is a t2 signal PSB3 BBCB is also T2.
I am doing very well since a further tweak to point more in the direction of the receiver, indeed I think I maybe had a problem with the signal to my recorder being too strong as "I was getting problem receiving signal" so no channels worked, however the from the RF loop trough to my USB DVB stick was working fine. I replaced the cable to that recorder with a poorer quality cable and it started working again.
So things are very good now, single figure bit error level at worst for Sky New sometimes 0 and the other channels are as good as that or better, most have no bit level error.
It is the best it has ever been really, almost perfect, I might be able to get a bit better as the aerial points up a bit but hardly worth the effort.
Only think I can't get is the local mux LNG, I have picked it up before, not sure why I can't get it now, it is much lower power though.
Weather is a bit different today maybe that help, but more the tweaking of the aerial and cables really I suspect.

Yea basically I can't pick up Notts TV ie LNG (local Nottingham?) as it is too low power, I might get it in a very good reception day, I have had it working before.
Then there is also COM8 which I cannot get, I should be according to the power level given here ie 13,400W
however I think that is wrong, I think it should be 1,340W, ie a tenth of the stated power and less than a 1/3 of the 5000 W LNG mux (Notts TV).
But basically I am pretty happy I can get all the channels I want in good quality now. I would not mind having Notts TV though as I live there, there is nothing on com8 I would miss.

Bit more tweaking and I managed to pull in a fairly decent Notts TV (LNG) but only if I switch my TV recorder off, it is that sensitive if I switch it on I lose the picture.
However it could just be a temporary thing as I have had it before and lost it, but the aerial is adjusted a lot better since then so I hope I have it watchable permanently, I now have all the T1 channels on Waltham, touch wood.

I note there a change of ariel type in march 31st to AK from W
What is happening? In particular regard to the power levels of the
signal already in the AK range which are low powered compared to the rest.
I am surprised there are no posts on this.

Well I am not fine, I expect I would lose Sky News and I have. It was moved. I cant get it any
more, there was poor info about it. Yes I have lost com5 I am not sure why I got confuse about
the whole thing.

OK panic over!! I got com5 back and SKY news. I watch Sky news 90% of the time so it would be a
big loss for me! I adjusted the aerial a bit. It is a good picture but it has a higher bit error level on it, it
was 0 before but the picture looks fine.
There are more changes coming those which I mention in an earlier post which may give problems,
I guess I will fined out when it happens. OK for now though.

StevensOnln1, I retuned the whole lot. I have just watched to SKY News which is show about as on
c56 but my TV shows it as on c37 freq 602mHz which is COM8, or rather was! com5 moved to
where com8 was. It is no wonder I get confused with all this!
The info on the freeview site is poor, it does not show what mux the channels are on etc..
This site needs updating too, Sky News is not longer on COM5
I seem to be OK now maybe I can tweak the aerial a bit to optimise signal levels, it is loft aerial.
Also I cant get 55 5STAR+1, 86 More4 1, 95 Freesports, 96 Forces TV, which are supposed to be on
com 8 going by the info above, I can get sky news which is on com8 but shown as on com5 above.
So all very confusing!!

Well I get a good notts TV on just 5kW on LNG channel 26 right at the bottom of the scale.

Freddy, don't know your set up, but you are aware Nottingham aerial are mounted vertically?
(Waltham horizontally).
Also there are almost in line were you are I think? Ie 180 degree between the bearings?
I am in Nottingham and have a loft aerial and have used both.
One of the problem I have had is that as they are almost in line I can pick up signals
"through the back" of the aerial even though they are the wrong orientation ie horizontal v vertical.
One issue is the TV may pick of a weak signal of the wrong orientation and store that and the
ignore the good signal when it gets to it depending one how it works.
As it happens I've lost my HD channels BBC1 HD etc.... but from Waltham, I am not sure why
as I get everything else. I never watch them really so not a big problem for me, my TV can't
pick up HD but my recorder and DVB-T2 stick can but neither pick them up, they used to!!

Another thing I have found is I do not get com6 on my TV, which is fairly old and cannot receive HD signal, I think that is why I can't get it, com6 shows up as as a T2 signal on my recorder which is HD, so I guess that is why I cant get it, I guess the SD channels on com 6 on can't be decoded on a T1 receiver.
I also found one of my shorter cables is not very good and replacing it with an even shorter cable improved things as it is a better quality cable. However I need to make up a longer cable when I have the time as it restricts where I can but the HD recorder it goes to.
OK I've made up a better cable and I have decent pictures on all channels but I think there will be some compromises due to it being in the loft where signals can be reflected, improving one channel usually means another channel gets a bit worse
Anyhow everything is pretty good at the moment. I will see how it goes, maybe I can find a better position to improve all signals however really I should get the outside aerial replaced with a digital one, however things have never really be bad enough for me to make the effort yet!
