Why are they switching analogue off?

[QUOTE="rolfw, post: 406564, member: 175057"] OK sorry, but it was beginning to sound that way. :) The digital signals are modulated onto a carrier wave. Whether the neighbouring analogue channels are there or not, makes no difference to being able to find the digital multiplexes, they are transmitted on their own carrier waves, what is received at the user end is a digital datastream. As far as I know and I'm not theoretically knowledgable, a carrier wave is neither analogue nor digital until it is modulated. I'd be interested to hear whether that is actually the case. :) [/QUOTE]
