Gary Faulkner: I assume that "U21" means UHF channel 21 is HD services from Sandy Heath which are available at your location.
I am surprised that the TV has not stored all services from one multiplex.
What you do depends on the design of the TV; what it will allow. You may find the Crystal Palace ITV1 HD in your 800s and you may just swap the two. Or you may delete the main ITV1 HD and manually add the CP one which is on C30.

Technical questions please.
1) When looping the aerial feed through a HDD/DVD recorder to a good quality digibox, does the signal to the digibox get amplified or reduced and by how many dB. I seem to have read somewhere that a + 3 db could occur?.
2) By what % does a 12 dB attenuator reduce the signal . By 90%?
3) With a 2 way passive splitter, is the signal split 50/50 assuming minimal down line coax cable
Tks.

Hi JB38
Thanks for reply.
When on analogue the signal was so poor I fitted a motorised aerial direction box.
At one time it was so bad I had to aim at
Chelmsford, I think, and watch Anglia so unless something remarkable has happened to
improve recption I don't think it can be too strong. My nieghbours at the side and behind
had the same trouble so we seem to be in a dead spot. I took the box back and swopped it
but the new one is the same.Is there any difference between a cheap box and a dearer one.Will try with indoor aerial and let you know
Dave

Hi,
I've lost the band of channels that includes film four, itv 4, yesterday etc. I've tried re-tuning my freeview box but they haven't returned. My signal is from the Crystal Palace transmitted. Can someone help me, in layman's terms, please? I not so good when it comes to technology.
Thanks for any replies,
Pam

David Taylor: Yes, try the set top or wire test, as now you are experiencing the same symptoms with your new box its definitely inclined to suggest instability in the tuner, and that can only really happen when the RF being fed into its tuner is intense to the extent that its causing self oscillation to occur, the audio/visual symptoms you describe being a classic one.
That said though, if it is instability, then what's seen should stop instantly if you pull the aerial out.
By the way, the only boxes that use what could be considered as higher grade tuners are Humax devices, as a huge range of boxes (about 15 or so) seen in places like Argos etc are all based on variations of Vestel (Turkey) chassis, the ironical thing being that its boxes with the more sensitive tuners that are first to suffer from RF overloading, boxes that are on the deaf side generally coping better in this type of situation, that being why some people with more than one box in their house finds that stations can be picked up one box and not the other, all down purely to the differing sensitivities involved.

Pam. Try a manual scan on channel 28 and see what happens.

For pvr's and HD recorders the top brands are humax and Panasonic and it would be wise to stick on these 2 brands only if in doubt as the other brands can be aerial quality /strength specific and may not be suitable at this time under varying condition's

Pam: What's the make and model?
If it's a Grundig GDB2 or GDB3, for example, then I wouldn't expect it to work with these channels from Crystal Palace as there is a known issue.

Pam: Sorry, I meant Goodmans GDB2 and GDB3 rather than Grundig. They both begin with a G!

jb38: My television signal comes from a block of flats across the road, going underground and then fed into the houses opposite!
I have no idea what is there, I just plug the aerial in from a wall socket.
TBH All seems well, but hopefully tomorrow will be the first evening I will be able to check everything since Wednesday.
