phil: You are not correct in what you state. StevensOnln1 has explained it correctly. Sometimes for obscure reasons tuners can miss a on an auto . If you've experienced those sort of issues (and you have an adequate - which might mean a new to achieve that!) then it often pays to do a factory reset/a complete scan with the aerial unplugged to clear all the stored information from the set and then start again.

Barrie Wreford: The power for COMs 7&8 has not changed since the UHF channel move. It is slightly lower than the other main muxes, but this should not affect your - especially if you can see the transmitter! This is also confirmed by the DigitalUK Coverage Checker Coverage Checker - Detailed View for your location. As others have mentioned previously, sometimes poorer reception on one mux can be due to a possible bad connection somewhere in your system. It would be worth checking through that all the connections, coax & aerial plugs/sockets etc are clean and free from corrosion or damage. I presume you have checked that the aerial hasn't moved in any recent high winds and is pointing correctly. If it's been installed for some considerable time, it could be worth checking the connections at the aerial itself if all else has failed to resolve the problem.

Chris.SE is correct in what he says about checking connections. I lost channel 36 (Com 7) on my lounge television, 33 and 35 (Arq. A and Com 8) worked okay, although the level wasn't fantastic. All other used channels.had reasonable' signal levels.

Problem was caused by a poor connection at the box, after a bit of wiggling channel 36 returned and the signal level on other channels also increased. So the moral of the story is check connections, even if other channels are working fine.

Terry: ITV is on UHF 54 from . ITV West is only available in SD on (the HD version is currently only available on ) so you will get a different if you watch ITV HD on Freeview.

Terry: David is very unlikely to respond to your query as his post is very very old, and his problem appears to be due to having an old band C/D .
In your case it's as StevensOnln1 explains, you will get ITV Central instead. This is because of the way ITV distributes the HD to transmitters - it's separate from the SD channel distribution.

If you've lost ITV3 in the last month it has moved. Its now on PSB2 (/738.0MHz) same as ITV, ITV2 and ITV4.

I was very pleased to see that the software on my TV (Bush Play HD 32" Argos special, bought just before Xmas) now has two options if you go for a full retune - the usual "replace all " and a new "update all channels" which keeps the channels in the order I want, rather than the muddled order they used to come in.

Just to update.

Got an guy from Aerial Express to come round and replace my aerial. Don't know the make or model, but the problem has gone, and I'm getting a strength of 10 where as before it was just one.

So sorted.

Thanks for the guys.

SJ Dunnett: There is no such thing as a . An aerial is a piece of metal which receives radio waves and does not know or care whether they are or digital. The for your postcode shows that you should get a good from the , although you are 52km away so you would be better off having an aerial fitted on the (of maybe in the ) rather than trying to use an indoor aerial.
