The symbol shows the location of the Oxford (Oxfordshire, England) transmitter which serves 410,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Oxford (Oxfordshire, England) mast?

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.

Thanks again jb for the advice, would this not effect my daughters tv running on the same Ariel? Also how would i get rid of these types of interference? Is there anything u can do? Or do i have to go to the expense of freesat?

rob: Some brands of Freeview receivers are more prone than others as far as reacting in an adverse way to any forms of localised interference that may happen to be around, and especially if the source of the interference is located nearby such as possibly from something sited on the other side of a properties separation wall, this being my reason for suggesting that if at all feasible to try the Sony TV up in your daughters bedroom, as you really do have to eliminate the possibility that the problem is associated with where the TV is presently located.
You could of course try your daughters TV on the aerial connection used by the Sony and see how it performs, but as aforementioned, interference affects some TV's more than others when operating "close" to a source of interference and so the test is more valid if the Sony is tested out using daughters aerial outlet point.
If though the problem still occurs then that could suggest that its down to a fault in the TV's tuner, because if the signal level received was totally over the top then its unlikely that your daughters TV would not be affected in some adverse way.
Another point I was wondering about being, as you are not using any form of powered splitter then what arrangement are you using to feed the aerial into the two outlet points?
Another test that I would like you to try is to carry out a signal strength / quality check on your daughters TV whist its on BBC1and making a note of the indications seen, then carrying out a similar check on the ITV1 channel followed by comparing that seen with the indications obtained from the BBC1 mux.
If for any reason the signal cannot be checked in this way on your daughters TV then go into the TV's tuning menu and select "manual tune" and entering C53 (BBC) into the channel box but with this action NOT being followed by pressing search or scan, as on most devices the level that the signal is being received at will appear in the strength / quality bars, on completion of the BBC1 indications carry out a similar check on the ITV1 mux by entering C60 into the box and giving an update on results.

Daughters tv has 64 strength and 99 quality on bbc 54 and 99 on itv. Will try and get Sony upstairs tomorrow. Splitter in loft is just one from screwfix with no power.
cheers

rob : Thanks for the update! I would also appreciate if you could let me have the model number of the Sony in question as I would like to check out the service manual for the set, this being something I should really have requested before now.
