I have an Acer touchscreen computer which has Freeview built in, for which I use a dedicated ariel which is ointed towards London.

For the past few months it has worked fine. However, recently I have been unable to get ITV1, CH4 or 5 because of a "weak signal". ITV2, 3 & 4 and all other channels still worked fine.

On Monday evening I decided to retune this and was surprised when ITV1 - Tyne Tees came up as a found channel. I live in the London/Anglia region. Anyway, following the retune I was able to watch all channels that evening no problem.

Last night, Tuesday, I switched on and ITV1 was again blank because of a weak signal - All other channels were fine. Another retune and once again only ITV1 Tyne Tees came up on the found channel list, but once completed I was again able to watch this channel with no problems. No doubt tonight I will be experiencing problems again.

Does anyone have any suggestions or know why the found list is showing Tyne Tees when I live in Southern England. I also noticed that lst night's returne brought up BBC1 North East & BBC2 North West! However the local news at 10pm on BBC1 was from London! Could it be to do with the hot weather?

Thanks in advance
