tonight I am getting a signal that popped up on 35-5 with a test pattern and tone with KRPC TV HOUSTON over the color bars. Anyone have any idea what this is? I did not rescan, this just showed up on 35-5, which must be the real RF channel, not along with 2-1, 2-2 and 2-3. Wondering what this is, and why this would show up without me having rescanned, although the tuner might be reading that it knows that something is being broadcast on RF 35 and just pick up any new subchannel on that signal. I am using a small portable TV to check the broadcast signals.
