“Speaking of which, which Baofeng-friendly frequencies are legal for anyone to use?”
The only legal way to use a Baofeng is on amateur (you know, ham) frequencies, and you must be a licensed ham.
Every other transmission on them is illegal.
But that hasn’t appeared to stop anybody.
Gotta catch them transmitting first. Legal to own and listen.
The smart ones will get a voice change app or something, say what they need to say in that, and broadcast that voice... you know if they wanted to do that.

They will work on the various ‘dot’ freqs too, and those are unlicensed.
