Andrew Wilkins: Yes, that's why it says "SDN, ArqA and ArqB restricted to 12.5kW after switchover until further notice." above.

I think I finally fixed my problem today! After reading through a lot of other peoples posts on this site it struck me that we all seem to be having different variations of the same problem so I used a signal meter on the incoming aerial lead which showed 'weak' signal. I then installed a mast amplifier on the aerial pole and the new reading showed 'strong' signal. I turned the amplifier adjusting screw slightly down and now have a 'good' signal and no problems on any channels. I wish I did this months ago - total cost £15 and an hour to install it.
I posted this as it may help others who are struggling with the loss of only some of the channels.

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?

nicola: See here:

Freeview signals: too much of a good thing is bad for you | ukfree.tv - independent free digital TV advice

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.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
