steve hooper: I think that the likely answer is yes.

The problem you have is probably due to the difference in strength of the Commercial channels relative to the Public Service ones. The Commercial channels are, after all, 50kW horizontally, which is stronger than some smaller main stations.

The higher power signals could be acting to desensitise your receiver making it more difficult to pick up the (relatively speaking) weaker ones.

You "may" be able to attenuate (all signals) and find a sweet spot where all will work fine, without the need to adjust your aerial. A variable attenuator allows adjustment, and these are usually (up to) 20dB. If you do try this, 20dB might not be enough, judging by your close proximity to the transmitter. You may need another attenuator, say 18dB or 24dB, and have this connected inline with the variable one.

See: Freeview signals: too much of a good thing is bad for you | ukfree.tv - independent free digital TV advice

Attenuators are available for a few pounds from sources such as eBay and Amazon.

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.

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
