Re: Turn up the wick!
Nope, the old DTV powers were roughly 17dB down on analogue. Post DSO powers are typically 6-10dB down (pretty much on all sites) - that was the whole point of DSO - switch off the high power analogue and you free up spectrum to increase digital powers.
Also, directly comparing analogue radiated powers with digital to establish coverage areas is not a good idea. Digital can work with much lower strengths than analogue. If you need proof of this just look at the radiated powers in the analogue system for analogue sound, and NICAM digital sound. The NICAM carrier powers were around 1/10 of the analogue power, yet NICAM could still give solid reception when both vision and analogue audio were very noisey and starting to fail.
However, as another poster has pointed out, the biggest problem for some people now will be too much signal, overloading all those cheap and nasty freview boxes. This is particulary so for those who have installed high gain "digital" aerials and amplifiers. It's been a problem in other parts of the country, and it's effect is for some channel to be missing completely and is difficult for people to diagnose correctly. At least with analogue, overloading was fairly self evident from floating pictures in the background.
