It’s also a federal offense to jam a frequency. I understand that legality is not the point of the post

This part bothered me. It starts out saying “these things are legal to own” and then explicitly says to do something illegal.

Legality ≠ morality, but you should be clear when mixing legal and not legal things.

It’s morally correct to smash a brick into a fascist government funded kidnapper’s face. It’s still illegal.
