Mike: The AFC (automatic frequency control) range in your Sony's tuner should be able to cope with plus or minus offsets on a frequency if its a device that's been manufactured within the last 4 years or so, these plus or minus offsets having been made to keep the correct 8mhz spacing between adjacent channels and to avoid any possibility of interference being caused, and with this not necessarily being caused to another channel within the same station but another station located within RF range, albeit that in Rowridges case the use of Ch22 (COM5/ArqA) necessitated it to also have a positive offset on its frequency.

Channel 30 still off. All other channels OK. Why?

If you're using mythtv and find you're missing epg data on some of the channels such as yesterday you'll find you have a missing networkid, full details here

Hi
Would appreciate very much suggestions/help as to why the following is happening. I have a Sony Bravia with built in Freeview tuner and recently on about 4 channels e.g Sky News and Dave etc and keep being told thet are not tuned. However have 2 Freeview boxes in use in rooms upstairs and no problems at all....I should point out all 3 are using same aerial and it is only a recent problem. Look forward to hearing from anybody [please.
Cheers

Harri Ackone: The most likely and most ideal solution is probably to switch your aerial from horizontal to vertical.
See the postings here from and in response to Brian Smith:
ITV 3 | ukfree.tv - independent free digital TV advice
As for why one might be unable to cope with the difference in signal levels where others will can, not all are the same. There are differing factors:
1. The sensitivity/tolerance of the components in the tuner.
2. The loss in the cable and connectors from the point that the signals are distributed.
You could try swapping your receivers from different aerial points, as a test. Before you move any, observe the signal strength (where they give such information) and see if the signal is shown as being stronger at another outlet.
If the Sony fairs better in another room, then maybe a bit of attenuation will lower signal levels and provide a more stable result.

Hi Dave Lindsay
Thanks for your feedbach it's very much appreciated but I don't think I'll be heading up to my roof to alter my aerial to vertical especially as I get vertigo!!!
This afternoon the missing channels returned a classic case of sods law methinks.
Would also appreciate an explanation in simple terms how one achieves this.."a bit of attenuation will lower signal levels and provide a more stable result"
Regards

Harri Ackone: I would like to clarify my last sentence of my earlier posting. There is no guarantee that attenuating will work. It is a try it and see sort of thing.
An attenuator reduces signal levels and an amplifier increases them. If you have an amplifier which splits the feed from your aerial to different rooms and it has a variable control on it and it is accessible, then you should try reducing the level of amplification before introducing an attenuator.
An attenuator connects in line with the aerial lead. Variable ones are available for £3 or £4 online from souces such as eBay and Amazon. One such example is here:
1-20dB variable digital tv aerial signal attenuator | eBay
The problem is that the signals that you are having difficulty with are weaker horizontally than the Public Service channels (BBC, ITV1, C4, C5 etc). Vertically they are the same. So you have a marked difference in strength.
Resolution of a picture with digital signals works or it doesn't work. There is a threshold known as the "cliff edge". So a slight change in signal (which happens all the time) has meant that the services are viewable again. Therefore, I wouldn't be surprised if it goes again.
Therefore, for reliable reception you need sufficient signal so that the natural slight changes do not leave you without enough (at some times).

Are we going to have fewer birds around the Solent after everyone's turned their aerials to vertical and they don't have anywhere to sit?
I was thinking of having mine turned just so I don't hear it shaking down the chimney when one of the fat pigeons lands.
