At last I've got to the 'bottom' of the problem, literally.
I think I've mentioned the occasional interuptions to my satellite reception before, but tonight I have photographic proof of the cause.
This is the normal view of the satellite dish, at roughly the angle the signal is received from.
But, add a smallish Trowie to the equation, and my X-Files suddenly stop, and "No Signal" is displayed on the dreaded blue screen.
Ducking for cover now,,,,
