Rob, just found this site TETRA and television interference from the national research-based TETRA Airwave safety campaign which says that interference from Tetra is more likely to be on Channel 60 (analogue in this 2005 case).
How far are you from the Police Tetra transmitter?
If you are in north west Kidlington, is your aerial pointing at the police transmitter when pointing to Oxford TV transmitter? If so, pointing the aerial a few degrees off will help.
If not too far away then any mismatch in the coax caused by breaks or unterminated spitters/ coax etc could allow this intermittent signal in. It is a harmonic of the radiated Tetra transmission so you would have to be reasonably close.
If you put in a Tetra filter it MUST be on the input side of any distribution amplifier, if you use one. Putting on the output or at the tv will not work as the distribution amp is reasonably wide-band and likely to have already amplified the interfering signal.
Incidentally, 4G causes interference on CH 59 as shown here

pikpilot: Yes indeed! but the filter referred to has a blocking effect on any channel over C60 as 790mhz as mentioned in the write up is halfway between C60 and C61.
I will also agree that Tetra interference had a far greater effect on the reception of analogue transmissions over that of DTT, but dependant on how close the transmission source is to a receiving aerial the form of interference it does create (picture break up) is usually of an intermittent nature.

Hi JB38 / Pickpilot
I am probably within 1/4 of a mile of the tetra station i think and i think it is new, emailed airwave the people who run them and they have emailed back saying that they are looking into it. Just purchased a tetra filter off ebay, says it will be here for Tuesday or before so will try that. The police station is near by and the Thames Valley police HQ has a massive tower which my Ariel pretty much points straight at, being this close to it, it is difficult to avoid.
If this does not cure it i think i will have to buy another TV, really dont get how its only affecting the Sony Bravia and Sony hdd / dvd player and seemingly only in one position. Scared however i will buy a TV it have the same issue and i can then not return it.
Again Thanks for all the help.

Rob : If, as was previously mentioned you manage to test the Sony out on your daughters aerial connection and with the result of this action being a reasonably glitch free C60, then interference from a Tetra transmitter cannot be involved as it would affect the TV no matter where it was installed in your property, however it would though be inclined to point to the source of the problem as being most likely connected with the equipment used by your next door neighbour, as the test you previously carried out using a temporary fly lead bypassing the under floor section of your cable still resulted in the problem being seen until you moved the TV away from the wall.
By the way, I feel it unlikely that any other device that you may decide to purchase would be affected in a similar way to that of the Sony.

Hi JB38,
why do you think that another new set would not be effected? I suppose i should stay away from Sony if i do by a new set. The Bravia is 5 to 6 years old, are tv's better shielded these days?
thanks
Rob

So, I have a tetra filter on the way but really i am not holding out any hope with that one. Going to take all of the gadgets from the tv today, Sony PS3 and hhd player and set top box and put them down the other end of the room to see it any of them are the problem. Then that's the end of me trying to get to the bottom of this, if it is next door there is not much i can do and to be honest i don't think it is, i have a 1930's house with solid walls so i doubt any signal could get through that.
The only other thing it can be is a fault on the Sony tuner around channel 60, The TV is under 5 years old so have contacted Sony as i am sure they used to come with a 5 year warranty.
Don't think the Ariel can be at fault as the picture is perfect on the Alba 300HD i have borrowed also i set the Ariel through my HHD recorder as the TV does not have a Quality meter (why the F not seeing its the most important) and all is looking good at 70 to 80 signal and 100 quality on all channels.
Thanks again all for your help.
Will keep you up to date
Regards
Rob

Hi All ,
Another update, unplugged all of the other gadgets and still and glitching. So i have moved the TV to the other end of the room with the fly lead and there we go it has not glitched once and i have been watching it for the last 45 mins. This defiantly means that the interference must be entering the TV from the back of the set from next door.
I have spoken to them and they have turned off there phone for a couple of days and that does not seem to have helped. They have a virgin cable and he has noticed the picture quality is not great on his TV, however it is all installed under there floor so moving it is not an option.
So the question now is what can i do to shield against the signal from entering the back of the TV as i don't think there is an option to change anything next door.
Again thanks for all your help.
Kind Regards
Rob.

Rob : Why should the TV tuner have a fault on that one RF channel? You could try checking it out on another aerial, just to make sure.
Considering how much you've spent on various filters, perhaps its time to call in a professional? The TV sounds fine overall (and although a Sony might have a five year warrenty via redemption, normally you only get a one year warrenty with a TV, unless the store gave you a five year warranty), so I suspect that its the feed from your aerial, with possibly interference from next door. Dont assume that a brick wall will stop intereference (its certainly does not stop noise, as I've found to my cost) - just check out which wifi networks your laptop can pick up, and you'll see what I mean.

Here's a little experiment you could try if you're reasonably handy with tools. Find a piece of plywood or hardboard that is larger than your TV set when stood on the floor behind it. Then lay some aluminium foil on the face of that board. probably best to glue it on with a little contact adhesive so it doesn't fall off. Then stand that against the wall, foil away from the TV, where you suspect the 'interference' is coming through. Then check your TV channels that have been causing annoyance.
Have they improved? If so then you have probably discovered where the problem originates, but more checks would be needed to identify the source.
(There is another check but that requires rather more 'DIY engineering' and connection to an Earth point. You could look up 'Faraday Cage' in a search engine. But if you try anything like that do, do, please be very careful of any electrical connections unless you are proficient with mains voltage electricity!).
