Yes, I did notice the news was in HD last night on KNDU. I am not sure either if it is actually and HD signal, as the picture quality was not that great. I think it is, but maybe they just haven't worked out all the kinks. I noticed their HD logo in the bottom right corner was on during most of their programming last night, and when Minute To Win It came on, half of the sound track was missing. You could hear the crowd cheering and the sound effects, but could not hear the main characters speaking. It was remedied by the end of the show, but was really odd.
By the way, sure glad Shane Edinger is back as co-anchor. Vast improvement over the previous guy.
Also, for you guys having trouble getting FOX in the Tri-Cities, 11.1 is VHF HI band, so you will need a VHF HI capable antenna, and the signal is coming from the Spout Springs area, some 70 miles away, so it has to be a pretty big one, AND aimed in that direction.
If you are aimed at the Tri-Cities from Walla Walla, you may need a rotator, or two separate antennas. You could have a UHF pointed at the Tri-Cities, and a VHF pointed at Spout Springs, that would get you all of the channels.
