Over the summer all freeview channels both standard and HD were fine from Blackhill.
In the last few weeks standard freeview is fine but HD has quality that jumps erratically sometimes even down to zero.

Thanks for the response Briantist.
The quality of my Freeview HD reception is now very good again.
Over the period where the quality was poor the weather was bad with lots of heavy rain and wind. The weather then improved and the quality was better.
On Thursday 8th Dec 2011 when the high winds hit the country the quality was bad again.
My aerial is in the loft but the weather does look like the most likely reason for my quality problems.

BigDave: I live approx 25 miles (Lenzie) from Blackhill transmitter with line of site on a good day. I have a Panasonic FreeviewHD TV. During the period mentioned about variable HD reception the signal strength on my set has remained at maximum even through the very poor weather of late. No problems with picture or sound quality on the HD or SD channels since TV purchased a year ago.

Jean: This could possibly be suggestive of a serious problem having developed with your TV's operating system, pity you hadn't mentioned the brand / model involved as it might have been possible to have checked this out.
The only thing you can really do is to leave the set unplugged from the mains supply for about 5 minutes or so before powering it up again when hopefully it might come back on with whatever showing in English, if it does immediately carry out a factory re-set, this maybe called "default setting" depending on the brand of set.

BigDave: Jean the position of the menu items on screen will be the same whatever the language. Look out your English manual to find what each item is and work from that. Good luck

Thanks BigDave for information on your Freeview HD reception during the bad weather.
I know now its definitely not the transmitter but I still think its the weather. It must be affecting my particular signal path in some way.
