And you know this how?
Because the program* I run each evening flagged up certain channels as "no signal being received."
*All right, I confess.
We expats who fled to the land of sun (that's a joke) and low taxation (even more of a joke) and exceptionally cheap excellent food and good wine (and luckily that's not a joke at all) expect to lose most TV channels on what is referred to as "SKY" but is actually "Astra SES" in the next two months. So as the dread date approaches, I run through the spectrum of all channels (except God and Allah channels) now and then and see what's happening. Interestingly, since the channels which went off reappeared again, my receiver is taking longer to lock up on them than before they went off.
