Thank you very much, Simon. I actually sent my post from the office and was not aware we had had a thunderstorm in the area on Saturday. The ITV channels were working last night (as they will do from time to time, to be more precise), and sometimes the E4 channels are the only ones affected and/or a number of 'minor' channels approx. between ch. 150 and 250 and approx. above ch. 530 on Sky. However, we have sort of learned to live with it, so it is not a major problem.
