Thanks for all you help. I've given up on Sandy Heath till Sept'11. Switched aerial to Waltham and now get 104 channels. Think missing Mux D though. Just pleased to get my sport back.
Plenty enit!!
I'll still monitor this site though.
I've read somewhere boosters amplify the interference and can make things worse, is that right?

JohnB: Yes, that is correct, amplifiers usually make things worse for digital reception.

perhaps a silly question but is the freeview signal in kettering running at maximum power now that analogue has been totally switched off... is the picture quality at maximum aswell.....my freeview picture quality is very good but even more quality is always welcome.

ray bayes: The signal strength and picture quality are quite unrelated - see How digital television works | ukfree.tv - independent free digital TV advice .

Bought a Panasonic tv with inbuilt freeview in December, since when have rarely switched on the Virgin box. Yesterday removed the Virgin box and installed a freeview+ recorder. The Teknika tv with inbuilt freeview we bought on 1st April for the bedroom now receives 0 signal! We tried it in the kitchen, where the Samsung tv with inbuilt freeview works fine.
Any idea what's gone wrong? Neither of us are particularly good at this kind of thing.
Many thanks.

Lou - Did the Teknika previously work? If so try again same place. Remember to connect the aerial lead!
Have you retuned it?
Does it recognise any channels?

MJ - If you have any amplifiers try without them. Signals can be TOO strong.
Do you have more than one set/ariel? If so, all same or various?
What do neighbours experience?

Rather annoyed here. I can't store the multiplex with Film4, Yesterday etc channels on it because that mux is identified as "Cambs & Beds." instead of "Cambs & Beds.." (two dots instead of one). My box doesn't like one transmitter having two different identifiers and there is no manual tune option, so that multiplex is now off limits to me. The signal quality is fine, as I can watch it on my old box. I've read another account like mine on Digital Spy, so I know I'm not alone. Most will probably think the signal quality isn't good enough and that's why they can't receive channels on the multiplex, but it's more likely due to the identifier typo. My old box didn't care, but my new one does, so that silly type needs fixing NOW.
Who should I tell? Can you pass this info on?
Cheers.
