So I just built my first SDR (not without problems) but I'm trying to find the control frequency for blount county. I can pick up sevier county's decently. I've looked at every frequency listed, and tried looking around through the entire 850mhz and 769-780mhz bands and can't find it. There's two towers within 15 miles of my house, and by estimation the sevier county one is 20 away. If anybody happens to know what it is, I'd appreciate it.
