I broke down and bought an HD TIVO today and an outdoor antenna that I mounted in my attic. Here are the results from my house in Kennewick near Sunset Elementary:
11-1 KFFX-DT (FOX) No signal.
19-1 KEPR-DT (CBS) Strong digital signal, SD with lots of analog video noise that looks like it's in the source. No macroblocking unlike the DirectTV feed. Toss up as to which I'd rather watch, I hope they get this fixed.
25-1 KNDU-DT (NBC) Strong digital signal, HD looks really really good. No macroblocking, Guide information is wrong except during prime time, often says 'SIGN OFF'. Once the guide starts working right, I'll never have to watch the DirectTV feed again, hopefully.
31-1 KTNU-DT (PBS) Strong digital signal, HD looks really really good. I'll actually start watching PBS again.
42-1 KVEW-DT (ABC) Strong digital signal, SD looks really good. No need to ever watch the DirectTV feed again, hopefully.
