Andy:
Thanks guys for all the info, much appreciated.

There are no wind turbines local to us and yes the system has been completed renewed, renewed with the best I could afford.

We have only lived here in this house for two months, having said that we have lived in this village for years and have only move to the top of the hill, down at our old house we had two aerials, one to Winter Hill and one to Moel y Parc, we use the Moel y Parc for BBC One as it was week at our old house from Winter Hill.

Even though here at the new house we have only one aerial pointing to Winter Hill we still get the Moel y Parc transmissions which are up in the 800s.

I have checked the info and the signal is 92% and the quality is 90% and we are tuned to Winter Hill transmitter.

Is the there to much signal?

Thanks for the info regarding engineering work but this has been ongoing for two months now!

we do have great line of sight to both Winter Hill and Moel y Parc, you can see both masts from this house at night with there long reaching red lights climbing into the air.

I really don't know what else I can have done, there is another Transmitter local to us at Elton but it is only a relay, we purchased a new Freeview full HD smart TV 6 weeks ago to enjoy HD but you cant enjoy much when the TV is sounding like it does and the picture is blocking.

Not sure this is of any help but BBC Three is defo the worst affected channel

Andy: Unfortunately, you can have too much signal, and here is a whole page about it:

Freeview signals: too much of a good thing is bad for you

92% is really high - my Sony PVR was on 93% with very occasional breakup, but a lot of tuners are less forgiving, sich as Panasonics. 75% is more than fine.

I hate to break it to you, but your problem sounds like the signal strength was too high for your equipment (what is it?), and that possibly caused the breakup of the picture. Getting high quality cable, a new aerial and F fittings may have actually made the problem worse (the booster would certainly have done). Remember that you can actually see the transmitters - so your signal was always going to be good, looking at the terrain plot and Digital UK's page. I suspect that your old house was lower down with perhaps low signal strength, and so you thought that the new house had the same problem.

The Moel channels in the 800's is what TV's ect do when they find an alternative transmitter, and you can actually use them if you like. However, they might not be strong enough to record from. Dave Lindsay and myself both have Sony PVR's which have robust but sensitive tuners. They can actually pull in signals from a whole host of transmitters, but at such little strength that nothing records, and it took a 12db filter for this problem to mostly fix itself in my case.

I bought some of these things: 12dB Coax Plug Inline ATTENUATOR: Amazon.co.uk: Electronics

Really cheap, and they work. Your best buying a mixture of different strengths, and trying one that works. If you need more, then you can put them in series. They actually fit togeather, and all you need is an extra aerial lead at one end so there is not strain on any sockets. There are variable ones, but it didn't work for me.

This might no be the answer, but you've got very little to lose by buying perhaps eight pounds worth of attentuators and giving it a go.

Hi. I'm in line of sight to the Rosneath transmitter, which is across the Clyde Estuary. Aerial on the roof. Not too sure how many splits are in the feed as we are in a block of 10 flats and there are 3 aerials on the roof. We have 4 aerial sockets in the flat, and I have been assured that there is a splitter/booster which splits our signal into these 4. On our main TV, I can receive most Freeview channels, apart from C54 and C60. These latter two have a signal strength of about 40-50% but a bit error rate of 2000+ making the picture unwatchable. Other channels have 45-75% strength and 0 bit error rate with a good picture. I've checked for interference (washing machine, fridge, central heating etc) but nothing seems to affect the results. The TV in the bedroom can pick up C60 no problem but as it isn't HD can't receive C54. Any thoughts?

Andy: get back the people who fitted the equipment you have paid for expensive equipment so you should expect it to work. If I had done the job I don't leave till it's right and don't take payment till the job is finished.

Tim H: You should carry out a test on the outlet socket used by your main TV by temporarily connecting the bedroom TV into it and selecting channel 60.

If the bedroom TV has a signal checking facility? check the strength of C60 whilst its still connected into the bedroom outlet, and use this for comparisons purposes against the indication obtained when its connected into the main sets outlet.

Of course, if your main TV is moveable? you could always try the test in reverse.

I can't get a signal on the tv or the bt box. We have bt internet and broadband
tonight.
I've tried unplugging everything and replugging it but no change.

Sharon: The most common answer to the issue of no channels being received is where a signal amplifier (booster) is being used and it failing or its power being turned off. This situation includes a communal aerial system, such as found in a block of flats.

Guys thanks again for the info.

I called the guy back and explained what had been happening and also explained that I had sort help from this web site, anyway he has fitted a 12dB attenuator, he reassures me this should do the trick.

He also informed me that the reading on his meter was 90dB at the aerial, this don't mean much to me but he said this was very high!

Had TV on now for 2 hours and haven't seen any signs of the picture breaking up or horrid noises, fingers crossed!

I never thought for one min that we would be getting to much signal, we live so far away from the Winter Hill transmitter I automatically thought it would be week, after reading MikeB reply and link it got me thinking!

Anyway so far so good! cheers guys for all your help, really appreciate it.

Andy: All I can say is if he has 90 dbuv at the aerial there is no need for an amplifier, with that amount of signal you could use an 8 way splitter and get great signal on all points.
