The symbol shows the location of the Oxford (Oxfordshire, England) transmitter which serves 410,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

In Swindon,from Oxford, MUXes C53 & C55 have zero Signal Srength this month. Why?
Your listings give C53 STILL @ 100kW.

Well that's it, my freesat dish and box arrive monday. I'm tired of being messed around by freeview. Transmitter catches fire in summer and takes months to fix, now half the channels are broadcast at low power and i just find out that is linked to London switch over schedule.but i expect yet another excuse for poor receeption once that happens. Can't get Dave or Yesterday or USA on Freesat, but at least I KNOW I can't get them, rather than the 'some days yes some days no' situation with freeview.

Andrew. I can fully understand you switching, I got freesat a while back too and it is certainly more reliable. The only downside is not all freeview channels are on freesat so I ended up keeping freeview as well.
Not wishing to teach my grandmother to suck eggs but have you tested your freeview signal strength with a meter? I had your problems and a meter showed me that my reception was weak. A mast amplifier cured it and all the previously bad channels are now fine. It maybe your signal strength is too high (unlikely by the sound of it) and remedies are available for that too.
It could be worth a try as, even if you get a perfect meter reading first time, at least you will know it's not your end causing the problem.

I note ITV 3 and associated channels were freezing last night between 10 and 11, as was said above it wouldn't hurt someone to put up a message as use to happen, 'Please do not adjust your set, we are experiencing technical problems at present' or such like.

Robert: You have to remember that the cause of varying reception qualities is not necessarily always because of anything being done at the transmitter, but more the case of normal changes in atmospheric conditions causing the signal to drop to a level approaching the threshold for reception in the receiving equipment being used, hence picture break up etc.
Of course it does have to be admitted that the other factor that does play a large part in the problem is that these normally occurring changes referred to always show up much more in cases where the signal being received is from a lower powered transmission source, i.e: the weaker the signal strength the more vulnerable it is to be affected by all sorts of problems even although the transmission power is still the same, this being why ad-hoc captions are not really appropriate as the intermittency of the problem is caused by nature and not man, the latter in most cases being unaware its occurring.

According to recently updated digital uk postcode checker
SDN mux C62 now apparently using the higher bandwith, slightly less robust FEC 3/4. And C62 will change to C50 in 2013

We are in kidlington and use a booster to split the aerial to 2 freeview boxes. Since the switchover we have a picture like a dvd skipping on all channels and sometimes the boxes will not record due to weak signal esp if both are on. We have turned the booster off but get no signal at all. My box tends to be the one that has the most problems my parents box seems to get priority. Any ideas?

I suggest that the problem is that your receivers are being overloaded due to too high a signal level.
If there is a variable control on the booster, try turning it right down.

thanks Dave
It isnt variable and turning of the power to it gives us nothing, do you suggest getting a variable booster

nicola: At about four miles from the transmitter, there is quite a possibility that you could remove the power booster and replace it with a non-powered splitter.
If you still have issues with reception (like you have now) then you might need an attenuator as well.
If I were you, I'd try disconnecting booster and connecting the incoming aerial lead to one of the feeds to one of the Freeview boxes. Then try the same with the other box and see what you get.
