Why am I still intermitently getting a "splintered" picture with squeaks on the sound with ITV3 from Hannington?
This used to happen while the old sytem was running but we were told that this would stop when digital was turned up to full power.

KMJ Derby. Thank you for your reply. I regret to say that I am not a technician and have no means of measuring signal strength or quality.
The problem only seems to happen with high atmos. pressure and there has been some improvement since switchover.

jb38 & Dave Lindsay: thanks for your help. The next time I have time to spare I will search for the signal strength.
Meanwhile: postcode is RG291PH, the TV is a Sony Bravia KDL-26V40xx and the aerial is routed through a Sony RDR HXD995.

Dave Lindsay and jb38. Thanks for your help.
My aerial points around 285 so should be good for Hannington. I already have an aerial booster. I usually notice the problem when watching recordings so see no point in re-wiring.
I have the TV manual but missed the tiny reference to signal strength on P27. So I used the DVD and went throuygh all channels. I either got red "no signal" or I got green with signal strength 90+% and quality good or better. This was with below standard atmos. pressure.
Have now repeated using the TV. BBC1 gives orange - signal strength high and ITV3/C41 gives a black 75% bar with signal strength "good".
Now that pressure is up, I got a slight flecking on ITV3 so I checked again and got the same result but the bar wavered slightly as I watched.
I would welcome any further comments but I still consider this to be a shortcoming of digital TV.

jb38. Thanks for the reply. Regrettably the booster is buried under many inches of insulation in the loft. I had to change it a year or so ago and have found the instruction leaflet. All it says is "Commtel Easy Install" and the only numbers refer to the connection diagram. Pretty useless.
I am fairly high up, AE is on the chimney and there are no trees nearby. Surely, if I have on obstruction in my signal path, won't it affect all or most of the signals?

jb38. Thanks for all that. Looks as if i will have to live with it. Moving the aerial involves two men and scaffolding due to 'Elf & Safety.
(For info. one daughter once lived in the shadow of the Crystal Pal. mast but couldn't get a signal from it!).

jb38: thanks for your comments earlier this month.
Your comment that it could be trees etc in the signal path is, I think, now proved as the arrival of the snow hanging on the trees everywhere has made ITV3 almost useless. I even had a few "flecks" on BBC2.
This morning I did a complete retune on both boxes (which seems to make no difference) and hope all will return to normal now that the thaw has arrived.
Thanks again for your help.

What is happening with the Hannington transmissions?
The last 2 or 3 days, in spite of low pressure, ITV3 is barely useable and now I am getting flecks and squeaks on BBC1, BBC2, ITV1 and BBC4.
This HD service seems to be getting worse.

Over the past two months my TV has deteriorated. ITV3 is unwatchable and BBC! is painful to watch.
I have all the symptoms listed in the at800.tv website of 4G interference but I am not in a 4G area.
Today I bought an 800Mcs filter but it has not made any difference.
Sony UK Technical Support (who are, of course in the US and 5 hours away) seem unable to solve this.
I appear to be the only house affected.
My postcode is RG29 1PH and tuned to Hannington.
I keep asking: what has changed in the last 2 months?

Did nobody consider the effects of high preesure when digital TV was invented?
