    Yeah, growing up there were people with illegal high power CB radios that would bleed into the TV signals near me. And I don’t even know if they’re close to the same band.

      Doesn’t need to be in the same band due to harmonics and power. If you keep splitting the 11m band (CB) into “fractional-frequencies”, you are going to get a cross-over somehow, especially if the fundamental is at super-high power.

      Using a piano as an example, if you play a C2 at 62.41Hz it still expresses harmonics at C3 (130.81Hz), G3 (196.22Hz) and C4 (261.63Hz) and at least in theory, to infinity and beyond! Each harmonic away from the fundamental will be expressed in decreasing levels of power. (It’s like 1/3 power per, I think. The proper math is out there though.)
