Sarah C: Hopefully it will be better come switchover next month.
Judging by the Digital UK predictor, you may be affected (before switchover only) by the Dover transmitter. So it's not forced to be a lowering of signal level from Bluebell, but the Dover signal is carrying a little further to affect your reception.
This won't be a problem after switchover because Bluebell and Dover don't share any frequencies.
Plus there is the fact that you're at the bottom of a 40m drop, but the transmitter is only 1.3 miles away. The higher power signal will hopefully get around the fact that you are at the bottom of a drop (and unable to "see" the transmitter):

charlotte harvey: I am not sure that the post code you've given is right.
If you are in Portreath, then you may have your aerial directed to the Portreath relay "filler-in" transmitter. This does not broadcast the Commercial multiplexes (which carry Viva, 4Music and other channels; it is used by Public Service Broadcasters only.
The reason for this is because the Commercial broadcasters' primary motivation is profit. They don't consider it worthwhile to pay for transmission equipment to be installed at Portreath and over 1,000 similar sites nationwide.
If you confirm your location, we may be able to assess the likelihood of receiving the Commercial channels from another transmitter. This will obviously require another aerial.

Colin Drinkwater: Those you have are those broadcast by the Tenbury Wells transmitter.
You "may" be able to receive from Sutton Coldfield at your location to give you the full complement of Freeview channels.

Dr W Thatcher: The answer to the question may depend on what transmitter(s) they are using.
The West Runton transmitter broadcasts Anglia regional programming, but does not carry the Commercial channels such as ITV3 or Film 4.
Those south of The Wash, along the North Norfolk coast, may have two aerials which were installed for analogue so that BBC Two and Channel 4 could be received from Belmont (the Yorkshire region transmitter) and BBC One and ITV could be received from a local relay. This allowed reception of Anglia regional programming. However, depending on the set-up, this may cause difficulty with reception of some digital services and may therefore require adjustment.
As well as answering the question, what transmitter(s) are they using, can you say whether they have more than one aerial connected (diplexed) together because this will likely have a bearing?

Trevor Wilson: Because there are fewer ITV1 HD regions than there are for ITV1. See ITV1+1, ITV1HD, BBC One HD regional services on Freeview | ukfree.tv - independent free digital TV advice

Mrs Morris: What's the model number of the Sony? This may help us find the user manual so as to be more specific in suggesting a fix.
The problem is because it is picking up signals from one of the transmitters in Wales, probably Moel-y-Parc.
Could you describe what Sony instructed you to do?

Jeff: Perhaps the signal level is on the high side, verging on being excessive at times.

It might be worth fitting an attenuator. These are available for £3 or £4 from various online sources.

Ted Hopper: Attenuation is probably the only thing you can try.
There is the possibility that some of the problem is interference from another transmitter which attenuation won't fix and which polarising your aerial vertically will probably help.

Gary: It could be that the signal is now on the high side and that a little attenuation may help you. See:

Sarah C: If your receiver has manual tuning, then you should go to the manual tuning function and tune to UHF channel 42.
When you do this, it may add the Pick TV and other programme channels broadcast on C42. Or it may give an indication that the signal strength is just under that needed to resolve a picture, in which case all you can do is try again at another time.
What has probably happened is that the signal strength has dropped under that which is needed to resolve a picture. The first thing NOT to do in such circumstances is do a full retune, as all that is achieved is the loss of the services from the receiver's memory. All you can do is try selecting the affected services (Pick TV etc) to see if they have returned. If they have not returned, you could have brought up the signal strength screen to see if there is a signal there, albeit it too low. As you have wiped the memory, you can't do this.
