I mean who can stop you from transmitting anything you want at any frequency? Licenses etc only matter when the rule of law is a thing.

It's trivially easy to watch the entire radio frequency range at once and triangulate the location of any transmission. If someone more powerful than you wants to stop you, they can.
Just curious what if the transmitter hops freq around? What is the tech to track these?
It's (scarily) available in the commercial sector[1][2] from space if you have the need to purchase their services.
Suffice to say, military and intelligence agencies are probably a few generations ahead of this and you won't find them commenting on strategic capabilities on HN.

Parent was asking about jamming protection (frequency-hopping, encryption) devices.
Once you transmitted, you’re exposed so the authority can find you sooner or later
Well yes but you could of course choose not to stay at the location you transmit from.
