Radio spectrum is licensed, and licenses are very expensive.
There are several bands for Amateur radio in US/EU/AU, but it is explicitly forbidden to use any kind of encryption on them. So no one can sell devices that use encryption on those bands.
And I doubt Iran was friendly to amateur radio in the first place. E.g. in USSR it was crazy to think of any non-approved radio.
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?

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.
