For the last few months, intermittent loss of reception of BBC channels only. Based in Cambridge, roof aerial. Channel 27 stations affected on two Freeview TVs (Sony Bravias). Signal strength is 100%, signal quality <10 - 20%. Have tried turning off various appliances to check for local interference, no change. Usually experience channel interference early morning, late at night, (including yesterday and this morning) but not every day. All other channels are fine.
Can you advise / help?

Fran: Your 100% signal strength is a bit of a giveaway. Your signal strength is far too high. Search 'Too Much of a good thing' on this site for more info.

Last night (i.e. 20th. July 2015) we ended up with blank screens on BBC1 & 2, plus severe pixelation on several oothers. But this morning, during a check-through, all seemed OK. Thank you. We only wish Freeview gave a clear message if the fault lay with themselves - otherwise one spends the evening checking & rechecking aerial cables & plugs. And the BBC News channel does seemed to have turned up elsewhere than the usual 130 channel. We live in NN18 8PT, with a loft aerial. (using Youview via TalkTalk). Now I know this opportunity exists, I shall report any further change.

Getting blocks on my screen on all hd channels you should boost your transmitter up .
I have a perfect aerial on my roof and my neighbours have the same issue so do my mates at the other side of town so it's you that's at fault so soft it out ...

David : This is a website independent of any broadcaster. It would be useful to know the name of the town as others may be experiencing the same problem and then we know whether this is related to one locality. It is possible that a fault could affect one side of a transmitter, which is why location is important.
If you are referring to the main HD multiplex, PSB3 aka "BBC B" -- which carries HD variants of BBC One, BBC Two, BBC Three, CBBC, ITV and Channel 4 -- then I'm sure that the BBC will be very interested to hear of a widespread issue. If this is due to a fault at the transmitter, only once notified can they move to fix it.
