Switchover starts in the Oxford area
This week sees the first stage of the digital television switchover for 415,700 homes in the Oxford area - one year after the only true problem during the whole of the UK pre-switchover process, the Oxford transmitter fire.
From 6am Wednesday 14th September 2011, you must to a perform a "first time installation" retune (sometimes "Factory Reset" or "Shipping Condition") on your Freeview box or television set if you use the Oxford full service Freeview transmitter.
This is because the old low power "multiplex 1" BBC service (on C34) will be replaced by the high power BBCA multiplex on the old analogue Channel 4 frequency, C53. Analogue Channel 4 moves to C63 for two weeks. Also multiplex C will move from C48 to C34 for two weeks as well.
If you use the Ascott under Wychwood (3pm), Charlbury (noon), Guiting Power (9am), Icomb Hill (9am) or Over Norton (9am) relay transmitters from mid-morning on Wednesday 14th September 2011 you will be able to receive the BBC Freeview services (with the exception of HD) for the first time, and you will no longer be able to view BBC TWO on analogue.
You MAY find that old equipment will no longer work - see TVs and boxes that do not support the 8k-mode
Another common problem at switchover is the ten-fold increase in signal from 10kW to 100kW will overload amplifiers and over-the-top aerial installations. If this is the case you will have to remove the booster or amplifier from the system, or perhaps fit an attenuator if you have no amplification.
On Wednesday 28th September 2011 will see the second stage of switchover, which provides the final Freeview configuration, including Freeview HD for all transmitters in this region.
On this date, you will need, once again, to do a "first time installation" as indicated above.
If you are over 75, you should already have been supplied new equipment by the Switchover Help Scheme.
Sam exactly the same problem for us after several a little stability. Who knows what is normal, all I can say is in our case New television, new aerial, new cabling F connects, and still problems. BBC Channels absolute fine. Not even a flicker on the signal strength monitor for ITV, assuming of course they are still on 68 which is not actually clear from the information.

After todays retune ITV1, CH4 & Five have gone completely. Thought it might be the amp, so have taken it out, but no difference. 1.1 miles from tranmitter, clear line of sight. Nothing else in the signal path within the house.
