Hah, that is such a late 2000s style video! I love it. That's genuinely interesting but also kind of frightening at the same time. I'm not sure this effect makes total sense to me, though. Normally, a radio signal is a single (center) frequency that is modulated by either amplitude or frequency shift. How can the sound coming from the arcing between the antenna and the grass be that clear at certain points in the video? If it were FM, I'd expect to hear mostly arcing and some faint audio signal a side effect of constant arcing, so maybe it's using AM? Maybe I'm just trying to find a reason to not believe what I saw.
