digital switch over has your area switched and is there any major difference, as usual west midlands is last just wondered what all fuss was about
freeview round my area is pretty pants, its hard to get a decent signal but some of my neighbours have a good signal, even with a new aerial i struggle which will probably be down to the trees etc
my question is once the digital switchover is done will they increase the signal strengh that my local station currently outputs?
No, there will be no change in strength of signal,

No, there will be no change in strength of signal, there will be more bandwidth available for HD broadcast, more channels and some spectrum to sell off for other uses.
You have to remember that there is no difference in the aerial required for analogue or digital broadcast. The difference is that analogue is more forgiving of poor signal. With digital broadcast, if there is a missing part of the signal its much more noticeable.
The first thing you'll likely notice is a distinct drop in picture quality on most channels. Its amazing how poor a freeview digital picture looks in comparison to a good analog picture (regardless of stb). Even the main BBC channels, which use relatively high bitrates, are inferior to a good analog picture.
Most areas that run both analog and digital signals tended to run the digital service on a very reduced power level. When analog is switched off these areas usually dramatically increase the transmitted power level of the digital signal.
Whilst what you mention about aerials is true enough you have to remember that there are some area's where the frequency has switched significantly into a new frequency group. If your in one of these areas and had a group aerial installed (rather than wideband) then you may require a new aerial. Afaik, these areas are likely to be fed by local relay transmitters rather than the main regional transmitters.
We had switch over on 17th and had to do a re-tune but wont get freeview hd until end of the month.
