Channel 4 Reception

I am in the West of Ireland. We usually have good Channel 4 reception, but for the last 2 days we just have a grainy screen. Could this be anything to do with the looming Analogue/Digital changeover.

Has anyone else experienced recent problems with Channel 4?

Thanks

Fog Maybe ?

Could be - Knock Airport has experienced difficulties over the last couple of days, and I'm not far from the airport. I'll keep my fingers crossed that it's nothing more serious.

Thanks
