Suppose,just supposing,if you bought a motor scooter for peanuts at a
scrap iron yard/junk yard.You took the scooter home and all it needed to
get it running real good is cleaning the spark plug and some fresh
gasoline and change the oil and filter(s).You decide you will once in a
while ride that scooter to work or to the stores or ride it around on
the streets/highways,just for fun.You still would have to get that
scooter registered and pay some money for a license plate for that
scooter.Operating a motor vehicle on public
streets.roads/highways/interstates is not a right,it is a privaledge.

Some radios,using them,even if you screw up,your license can get yanked
away from you.So,get a license (if a license is required for such and
such whatever kind of radio(s) to use that radio and keep the FCC off of
your back.
