Gareth: I see nobody has responded, what you've missed is the retune was needed after the 28th, not before!
Follow the advice I've just given for James.

Robin barker: You haven't made it clear what you are receiving now or what you were getting before the 28th Sept. There are a number of options depending on which way your aerial is pointing.
In any event try a full factory reset/new install with the aerial disconnected, and then repeat with the aerial connected.
You may have do do a manual install because you may pick up transmissions from Wenvoe.
If so, the UHF channels for Mendip are C61,C54,C48,C52,C67 & if you have HD C58.
If you are still missing the Arq A (COM5) MUX on C67, you may get enough signal from Wenvoe, so try C49.

derek gregory: When you say communal aerial
system cabled into the house, do you mean it's supplied by an "association" and you have a feed?
If a full factory reset/new install does not solve your problem (see the Link "Freeview reset procedure" in the yellow box below) then you will need to get onto the owners of the aerial system as it's probably channelised and needs changing. There will be a similar issue in March 2012 if this is the case, and you may have had problems in January and last year during DSO.
As you haven't supplied a postcode, I don't know what other transmitters you nay pickup, so you may need to do a manual retune, if so see the post above to Robin.

Stan Hill: It's probable that you are getting some signals from Wenvoe which is confusing the situation.
Try a full factory reset/new install with the aerial unplugged to completely clear all previous setting and channel.
Then with the aerial reconnected, try a new MANUAL install using UHF channels C61,C54,C48,C52,C67 & if you have HD C58.
The link below in the yellow box "Freeview reset procedure" has some details on the reset.

Brian: same thing applies to you as to Stan. As you haven't given a postcode I can't say how good a signal you should normally get, but try the reset & manual install as detailed above.

Son in Law: you could be getting other transmitters as well. Try the reset & manual install as detail above.

Ryan:
John Gaunt:
Neither of you have given a postcode, so I can't be of specific help.
You both may be getting more than one transmitter or too much signal now power has increased.
So first try a full reset/new install with the aerial unplugged to clear all previous settings and channels (the link "Freeview reset procedure" in the yellow box below has some more details), then reconnect the aerial and do a MANUAL install using Sutton Coldfield UHF channels C43,C46,C42,C45,C39 and if you have HD C40.
Then, if you are still suffering picture breakup etc, if you have any booster/amplifiers in circuit, remove them and see if things improve.

OK, we need to correct some misunderstood information here -
1) The 3 PSB muxes at Oxford are on full power of 100Kw. The 3 COM muxes are on restricted power of 12.5Kw until April 2012.
2) Log periodic aerials DO have gain, usually not as high as some of the "high gain" aerials being used, unless they have built in amplifiers.
3) I would not recommend Jonathan change his aerial at this time due to his situation and variabilty of received signal.
4) You do NOT get "snow" on digital signals.
You either have an adequate quality signal - perfect picture, or not - no picture or pixelation if right on the "cliff edge". This can occur if the signal is weak or suffering interference.
You can also get picture/sound breakup or no apparent signal at a set/box with too strong a signal.
5) The only reliable way to be sure is with a proper signal strength meter.
Jonathan: does it not say what the aerial is on your receipt? You could always ring Oxford aerials and ask what they put in if the information is not there.
If we know, then it'll give an idea of what attenuation is needed and you can then see how stable the situation is over time and with the changing season. In the longer term changing the aerial may be an option.
You are correct to put the attenuator direct into the wall socket, in the middle of flying leads is not a good idea. The other place would be direct into the back of the set/box, perhaps the place for the fixed one you have ordered.
It wouldn't be a bad idea to check the connections at the back of the wall socket and anywhere else there may be connections between the socket and the aerial - did they put new coax in for you as well?

James: Sorry, it doesnt look as though anyone has responded to your query. I'm not clear when you last did a retune, but if it was before the 28th Sept. then you need to do another.
It's best to do a complete factory reset/new install, first with the aerial unplugged to clear all previous settings, then do it again with the aerial reconnected. See My Freeview box has no EPG, is blank on FIVE, ITV3, ITV4, ITV2+1, has no sound or the channel line up is wrong | ukfree.tv - independent free digital TV advice for more information.
If that doesn't solve the problem, remove the booster and try again.
