Hi all! Here is one way to get over 'No Signal' problems is the way my daughter used when Divis was off. We were watching Law and Order on Channel 5 and when Divis went down was to watch the remainder of the show via the internet. It looks like some of the muxs are still off air at 12.30am Sunday.

Another good reason to have Freesat as a back up, even if you have good terrestrial reception.
I well remember the major fault at Divis in the late 70's (or was it the early 80's ?) when we had no TV for almost a week. The transmitter was subsequently on low power4 for several months afterwards.
Satellite or cable didn't exist in those days, so it was all very frustrating!
