As you may have guessed, I'm a bit of a fan of television and have spent some time
browsing TV relevant sites and I've picked up some info. As with all internet sites
there's the possibility that it might be wildly wrong, but it seemed plausible. I think
there might be some technical people here too, so they can correct and supplement
this info (please

)
I understand that the current analogue signal can interfere with the regular terrestrial
one and is not yet being broadcast at full power. Once the switchoff happens it will
be, and presumably the stronger signal will be picked up by everyone who has the
necessary equipment and who is in the line of sight of a transmitter (I think there's
some technical geewhizzery that can help with this too).
Certainly can't pretend to understand it - I live in South London and my parents in North
and yet according to the coverage reports we're both receiving our signal from the same
transmitter... (Crystal palace).
Each of the digital channels is broadcast within a multiplex and so if you are having
trouble with several channels it is worth noting this as that might give you a clue as to
which multiplex you're having problems with. This might be fixable by adjusting your
aerial or you may have to buy a new one. Wikipedia has updated info on all the
multiplexes (it will also explain why UKTV History is switched off Freeview at 6pm).
Apart from Wikipedia I recommend these websites for information specifically about
Freeview and connection troubleshooting:

Anyway, since this is the bushcraft subforum I thought I'd try and put a bushcraft slant
on things by searching for 'bushcraft digital' and I found this, which certainly puts a fresh
perspective on not being able to see things
