My experience with VHF on digital has been mostly positive. I had to get my rabbit ears up high enough to get the station 22 miles from my house that operates with less than 10 kw of power, but it comes in better now on DT-8 than it did on DT-36. What it seems to go back to is something you may have heard me say about radio that also applies to TV. It's not something people will work at to enjoy. Most people don't understand the limitations of their antennas and aren't willing to do the research and work necessary to put their antenna in a good spot. I'm also not sure that going to all UHF would have turned out the way so many people think. I have a friend in Kansas City, where all TV is UHF (unless you're trying to get a couple of stations from Topeka), and he can't get 3 stations there despite being fairly close to their towers and being able to get other stations on the exact same towers!
KSAT, by the way, is a station I've heard a lot of people say they can't get, even from a few who can get KCWX!
