Also in W3 and have the same problem as Michael O'Connor.

Only got HD TV two days ago so don't know if this is a new problem.

First two attmpts were unsuccessful and third attempt ended up on page 38. So here goes again:

I'm also in W3 and have the same problem as Michael O'Connor.

This is my first HD TV and I've only been 'experimenting' for the past two days so don't know if it's a new problem.

Thank you for clarifying that.

Is there any reason why W3 should be a bad area for HD?

Peter: Beardsley Way looks like blocks of flats on the Birds Eye view on Bing Maps, are you using a communal system?

If you are, you may find that your building's owner has used a channelised system, which filters and distributes only the that used before HD was added. It would need to be extended for HD, to include as well as all the others. You may find that they're not willing to do this, given it's now less than a year before the whole thing will need to be reconfigured for .

If you have your own aerial, I can't see what the problem would be, as this is a very strong area. See for thoughts on what might be blocking this one frequency.

Thank you for the reply and for going to the trouble of looking me up on the map.

Yes, it's a block of flats with a communal giving good on all the other ( and digital).

When I tried to do a manual retune last night it showed pretty much 100% signal strength on all channels except 31 (which showed 0%).

The aerial system receives regular maintenance, but as you say, I'm not sure if any necessary adjustments have been made for HD (although it has been available for some 2 yrs.).

Until some years ago I used to use an indoor aerial which gave great analogue reception despite being pointed at the . Would it be worth trying this option, or would it not be suitable for digital and HD?

It might work but try, if you can to get the best line of site that you can. There would be no harm in trying.
