I live in the Portland, OR area and I want to get the local channels such as Fox, KOIN, and so on, but I am only getting these 29.1 - 29.7 channels and not getting any of the Portland loc channels. How does this stupid TV work? I have an antenna hooked up to my TV. I scanned for local channels and only found 7 channels which is the 29.1 - 29.7 channels and those aren't the local channels. So confused on how this thing works.
