Mike: Many thanks for the update as is always interesting to know the result of anything tried, even although if it might well be in a negative sense! Just a pity you didn't have a normal Freeview box to try out on your aerial (box connected to your TV via a scart lead) as although I know you were using the PC's-TV tuner to judge against the tuner / receiver in the TV its not really the best of devices to use for comparisons, albeit that it might well be OK for the purpose intended.
I think though that the latter comment you made in the update is best policy, as although you will always get someone finding fault with something, it wasn't exactly easy to read anything other than derogatory comments about that particular model of TV, albeit on the face of it nothing would seem amiss, especially with it having an M &S tag on it.

hi, im soooooo confused :-(
i live in far cotton northampton and should get all sandy channels.
i can today get bbca, d3+4 & sdn on ch 31.
this website states sdn should be transmitted at only 20,000 watts, i dont understand that i can get this but i cant get arqa or arqb which are supposed to be transmitted at 180,000 & 170,000 watts?
also i have gold but it isnt listed?
can anyone explain please?

barclay: The only thing I can see that could be the issue is that ArqA and ArqB are on Group B channels (higher up frequencies).
Have you had your Group A aerial replaced with a wideband one (or a second aerial fitted for higher frequencies)?
I'm not saying that this is the problem, but it is an observation of a possibility.
Have you tried manually tuning in these channels? Does the bar show any signal whatsoever?

hi dave,
thanks for the reply, i had a good wideband in the loft but couldnt get sdn so ive just connected up the old ariel outside so you are probably right, i cant spend the money on replacing it as we are moving soon.
thanks

Why is it that I am unable to receive certain Freeview channels in Northampton NN3 that friends living in Wootton NN4 take for granted? Why? When considering BT Vision - out of the 72 Freeview channels available, there are apparently 53 channels I can't get. It does make Digital TV look a bit of a joke ! How can I progress ?

Dawn Bonham: Around 8% of the population can only get the Public Service Broadcaster (PSB) services because the commercial broadcasters don't wish to install transmitters to cover them.
However, I'm not convinced that this affects you as there are no small transmitters in your area that only carry the PSBs.
In order to give a more precise answer, an exact location is required. As too is the transmitter from which you are receiving your signal. If the transmitter is unknown, then the direction of the aerial along with the location should allow it to be worked out.
If it is the commercial channels that you are missing, then perhaps you are receiving from Oxford transmitter. I say this because its commercial services are on low power until 18th April. This is so as to avoid interference with another transmitter that has yet to switch over to digital and is therefore using the same frequencies until then.

Harry : Apologies, the database flag for SDN being on low power had been removed by accident. I have restored the information, see above.
