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.
