Rob: Being located at only 4.7 miles away from the Oxford transmitter and with a clear line-of-sight from same then I would be inclined to carry out a test on the ITV1 mux using either a non-powered set top aerial or alternatively a short length of wire (about 6 feet or so) connected into the TV's aerial socket, because if the signal received on C60 is indeed grossly excessive then it should be possible to obtain a reasonable picture of sorts using an improvised aerial, this of course being done purely for test purposes.

As far as your main aerial is concerned, something such as a Log 36 would be ideal for your situation as this has an element of protection against 4G transmissions, that is should you ever be affected by same.

Rob : I would also follow David Pinfold's advice as far as temporarily bypassing any powered splitters should you be using same? although before doing so I would try a test by connecting the attenuator between the aerial and the input to the distribution amplifier just in case the high signal level being received is triggering instability in the amplifiers circuitry.

Thanks again for the advice, no powered splitters at all or amplifiers on the system. Also my daughter had no issues with her tv in her room which come from the same Ariel. Only seems to be an issue on the Sony but only recently. Really confusing, if i turn the signal down with an attenuator in the back of the tv to get around 75 % on the effected channels i then loose bbc 1 and quest and lots of other channels. The interference seems to be ok when you first turn over to the effected channels but then starts to get blocky again.

Jb38 just plugged in unpowered set top Ariel as suggested and 100 % on the effected channels still. However like i say how do i turn this signal down without effecting the other channels

Have also noticed the signal on one of the effected channel go's from high to nothing then straight back on. Is this the signal clipping because its too high? So confused on this one.

thanks for the help so far but more required unfortunately.

regards
Rob

I would say yes this is probably signal clipping. Just one suggestion take your daughters TV down to where your sony is just to see how that works. I know it is unlikely but there may be a fault with your sony tv if it has been working ok til now.

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?
