This is not at all true in the US: it is not "technically illegal" to own transmit-capable equipment without a license.

It is true that transmissions are regulated by law in every country, and the particular license you need will be determined by frequency band and power. In the US, there are some cases ("Part 15") where no license is required.

Yeah, GMRS band is actually pretty permissive as long as you stay under the power limit(5W?).

as noted above "part 15" rules actually allow low-power transmission along a multitude of bands. In some bands you are restricted to only a few mw of power, others like the scientific bands allow more.
