Oxford sees the end of analogue TV as high power digital starts
If you live in Oxford, High Wycombe or Swindon or in Oxfordshire, you will need to take action on Wednesday morning as high power digital television services bring digital and high definition television to everyone.
Most people need only perform a "full retune" on their Freeview box or TV, but it would be impossible with 415,700 homes covered by the transmitters, for no-one to have a problem.
From Wednesday 28th September 2011 you MUST have a digital television device to watch TV. If you do not have a digital receiver, from Wednesday will have a blank screen.
Do not expect a terrestrial television service from midnight until 6am - or a late as 3pm on relay transmitters (see below for timetable).
Switchover help scheme
If you are over 75, get (or could get) Disability Living Allowance, Attendance Allowance, Constant Attendance Allowance or mobility supplement; or have lived in a care home for six months or more; or are registered blind or partially sighted and need assistance, please see The Switchover Help Scheme.
Cable and satellite
Cable (Virgin Media) and satellite (Sky, Freesat, fSfS) viewers are not affected by the changes. Remember, however, that you may be using analogue TV to watch on a second or third set and it might need a Freeview box.
If you are not on the list, you should scan your box from around 6am.
When you now rescan, you MUST do a "first time installation" or "factory reset" scan (sometimes called "shipping state"), not a simple "add channels". Do the procedure you did on "national retune day", September 30th 2009, see Freeview Retune - list of manuals.
If you live close to the transmitter, you may have to disconnect any "boosters" from your aerial system. The new, more powerful digital signals may overload any amplifiers and result in no reception! When looking for them include a check for distribution amplifiers, loft boxes, set back amplifiers, bypass Amplifiers, hidden masthead amps in a loft space and any dodgy active splitters.
If you had no Freeview service before, you will have the BBC channels digitally from Wednesday 14th September 2011. This is a single multiplex of the BBC channels (radio, television and text) for most people.
However, if you were on the fringes of reception from one of the main Freeview transmitters, you will now get all the Freeview channels.
If you didn't get this limited Freeview service on 14th September 2011 then you may need a new aerial.
If you are served by a public service (relay) transmitter, which are:
...you now need, from around from 6am (unless shown otherwise) on 28th September 2011 to rescan, and you will get a second Multiplex with ITV 1, ITV 2, ITV 1 +1, Channel 4, Channel 5, Channel 4+1, E4 and More4.
The old analogue TV signals provided lots of nations and regions for the public service channels, and these have large areas of overlap.
The old low power digital TV signals were at very low levels and reception of signals from more than one transmitter was a rare event.
All Freeview boxes automatically scan the available broadcast frequencies looking for channels, and they do this from C21 to C69. Older Freeview boxes will, if a duplicate version of a channel is found whilst scanning, such as another BBC Oneregion, placed it in the 800-899 channel range.
Some of the latest Freeview boxes will pick the strongest signals for the "primary" number positions, and some will detect the different regions providing a choice when you perform a "scan for channels".
The 800-899 is easy to access by pressing CH- from 1, and in most programme guides is just a single scroll up.
Briantist:Iv got a freeview box but im not a big fun of them, i aslo have a skybox. Hannington swithces to digital in feb 2012 so until then i still have my ceefax. When that happens i repoint my ariel to oxfordtransmitter and get myself a new tv. Its not just me but i notice other people pointing their ariel to the Hannington transmitter, they all must like their ceefax...!! Digital ceefax/teletext is just not the same... :(
John: you might also be picking up the Mendip MUX for ITV etc.
Without a full postcode, can't tell you how reliable a signal you should be getting from Oxford (or Mendip). Did you get all the MUXes before the switchover?
Boa Gongrui: Double posting on different boards is not helpful. I have replied on the main Oxford board. The DSO at Oxford went ok, The 3 main PSB muxes are now transmitting on full power (100Kw) which means anyone close to the transmitter may now be having overload issues and should try without a booster if they have one.
The 3 COM muxes however, are on restricted power (12.5Kw) until April 2012. This should not be an issue for anyone close to the transmitter as it is only 9dB below the PSBs. Anyone in a fringe or poor signal area may have problems until the power up, but if they has all the muxes before DSO you should have them all now.
In any event, if you've gone to Sky, I don't know why you are posting here.
