FPV Video Low Band Is Illegal

If you are using the L-band for FPV video in the United States and Europe (and probably many other places), you are probably breaking the law. And not just a little "look the other way" violation like flying FPV without a HAM license.
NOTE: Throughout this video, I refer to the ISM band as ending at 5825 MHz. This is incorrect. It ends at 5875 MHz. I don't know what I was thinking.
