Algernon Black: "End situation: Dec 13" shows up on every postcode, except at the Oxford transmitter, where there seems to be a reception change for the SDN mux. No idea why, but it's not a retune event as you mentioned previously.
You could try contacting Digital UK and see what they have to say.

rob: There is no scheduled re-tune for the remainder of this year. Unless there are technical changes to the configuration of the multiplexes you only need to re-tune if a new service is added to an existing mux (and you wish to view it) or a new mux is introduced which you wish to receive. 2014 will see local TV and/or additional HD muxes added to a number of masts, but your existing services are expected to continue on the current frequencies until around 2018 before frequencies could once again be shuffled about.

Thanks to all for the relevant info. I have tried contacting Digital TV and Arquiver all to no avail.
I have now asked my MP to ask Arquiver and OFCOM why Oxford has such poor and unacceptable transmissions, pointing out that the advertisers could be upset that very few people are seeing their ads after they have paid so much money!
If we get no better transmissions I shall write to the newspapers to get people to stop paying their license fees.

We are having a lot of problems tuning our Sony Bravia to the Oxford Freeview channels. One night only BBC and now only ITV and porn channels. Something bad is happening on this transmitter. We have a very good signal.

David Clover: Whats your postcode, it will really help in getting to the cause of the problem.
The same goes for Algernon Black - if you want help, we need to know where you are, to check signal path, etc.

hieu: Firstly, thanks for the postcode (makes life so much easier!).
Secondly - why are you using Oxford? The Digital UK tradeview shows your 73km from the Oxford transmitter (its doesn't even show up on the terrain plot), whereas Sandy Heath and Waltham are much closer, and give a good signal path.
OK - if your are using Oxford, there (according th the R +T investigation) no problems with the transmitter, so I suspect the problems in your house. Check back from the TV - is there a cable loose? If your aerial is in the loft, check that its connected properly, and if you have some sort of distribution system, make sure that verything works properly. If its only the roof, again much the same.
Even if a transmitter is off, unless its some sort of emergency, its seldom very long, and enginnering work tends to mean a reduced signal, rather than nothing at all.

Tim: We have been struggling to maintain a decent reception on most channels for over a month now (previously all were good). Sometimes the HD channels were fine, other times normal digital were better. Finally I have given up and reset factory settings on my Bravia tv. Now i have only about a dozen channels and all are completely unwatchable (due to reception quality, not content).
I have used an aerial and booster in the loft for the past 3 years with no issues and haven't changed anything regarding cables or other electrical/electronics.
