I pick up KXII 12.1, 12.2, 12.3 from 62 miles away, with a good UHF antenna and preamp.; tower is across the border in S. Okla. 12.1 (CBS-HD) is as least as good, or better, to my eyes, than CBS from Dallas HD LIL on my Vip622. FOX HD is also sharp, but for now has backed off temporarily from 16:9 to 4:3 - but still in 720p. The 12.2 (MyTv) is 480i and 4:3, but the picture looks fine to me for an SD picture.
I have a Vip622 (HDMI input), HDTV tuner card in my PC, and a Samsung DTB-H260F HD receiver feeding a Component input on my Samsung DLP. KXII 12.1, 12.2, 12.3 looks great to me on all three receivers. PC HDTV tuner is viewed on a Samsung 22-inch 16:9 5ms LCD monitor (1680x1050). KXII channels are beautiful on this setup.
The good news is that the KXII signals practically never have any breakup - as long as you get a good signal like I do. I can't say the same for E* Dallas HD LIL, where NBC and FOX (in particular) have many problems with the picture breaking up.
Sometimes, I will A/B CBS HD Dallas and KXII CBS HD. When Dallas LIL HD is breaking up, CBS at KXII is nearly always perfect. I use these comparisons to report problems to E*. I also get NBC HD and CW from another Okla. OTA station, KTEN 10.1 and 10.2. Also a more stable picture than E* Dallas NBC LIL HD. CW is morse code to me. Don't care about the channel being there.
I am not as fussy as many about picture quality, I guess. But, if you sat in my house and watched KXII on my Samsung DLP or PC LCD, I doubt you would complain about the picture quality. The station engineer explained the new setup to me, but it was way over my head. Am going to have lunch with the engineer and tour the station. Maybe I will then understand the technology better.
You'all come. Bring your own chips and drinks. Think positively. Maybe you can cram 5 pounds of candy in a 3-pound sack. And it all tastes good.
