Just as a guide there has definitely been no issues with Beckley. All channels working perfectly here in Banbury

Thanks David, might try that, really tricky one, like i say if i turn the signal down with the attenuator i then don't have enough signal for the other channels which are not effected. When did this signal get so strong. Don't understand it and why is it only on the one mux

rob: I suspected that might be the case! and which could suggest that your problem is possibly down to other than a grossly excessive signal level but more one caused by RF instability occurring in the system, and going by what you have reported possibly even occurring from within the Sony's tuner! .
I would therefore like you to try another few tests but purely concentrating on C60, as I have a feeling that the excessive level being indicated using the set top aerial is not fully from the transmitter but possibly from some source of localised interference, and so I would like to know the answers to the following.
Is your Sony TV positioned next to a wall of an adjoining property? and if it is and the set top aerial is similarly positioned then move it (the aerial) away from the wall as far as you can manage, also try positioning the set top aerial near to (or on) the floor level.
If that said does not apply or has not made any difference, then try a short piece of wire (about 12") connected into the TV's aerial socket whilst on C60, if nothing is seen then hold the end of the wire and see if this makes any difference?
If your Sony TV is free standing and is not mounted on a wall, then if at all possible I would like you to try it out on your daughters aerial socket
You should also try carrying out a factory reset on the TV followed by retuning it via a "first time installation".
The tests requested might all appear to be unconnected but they all help to build up a picture as to the possible reason for your problem, as I have my doubts that its purely being caused by an excessive signal level being received, because if it was the set top aerial test should have partially resolved the problem.

Jb, yes the tv is next to a wall of an adjoining property, plugged the set top Ariel in and moved as far from the wall and still has100% signal showing on the signal meter. Also put it onto the floor and still 100%. How does that work?
why is the interference only effecting the one mux?

The signal is 100% with the set top, but still some interference but that could be cars, could this mean an Ariel replacement is required? Really confusing me.

Does seem like less interference on set top Ariel. Still blipping but not as bad, still driving me mad, do i need a high pass filter?

Update, started again with set top Ariel and really breaking up so back on main Ariel again. Might be some local interference but why only on channel 60 tv stations?

rob: I wonder if this could be due to the presence of a 4G base station operating in the 800MHz band (C61 upwards). It might be worth enquirying with at800 to see if this could be a possibility:

Cheers David, have checked already but they say there is nothing online in my area at the moment. Could it be from the police headquarters or a baby monitor or something as we have new neighbors with a baby, there seems to be no pattern to it, but all on channel 60 only nothing else.

rob: If indeed your problem is being caused by some form of localised interference then its likely to be a harmonic of whatever is causing the problems fundamental operating frequency and not something actually transmitting on C60, as harmonics (especially from a transmitter device located nearby) can in many instances be just as bad, although harmonic signal interference usually falls off rapidly as you move away from the source, this being why I suggested moving the set top aerial away from the TV and also trying a test by connecting the Sony TV into your daughters aerial socket which I believe to be upstairs?
Another possible source of interference is from "some" types of broadband powerline adaptors, as they can introduce harmonics into the ring mains wiring system.
Tetra interference is another possible source, as the first harmonic from a Tetra base station (on high 395 Mhz) as used by the Police / Fire services etc is close enough to C60 to cause problems.
