Transmitters are not licensed — either for use by Part 15 operators, or by licensed broadcast stations.
In the case of licensed AM/FM broadcast stations, that license is issued to the successful legal entity that applied for it, after proving that their installation complied with the technical details given in its FCC construction permit.
Unlicensed Part 15 AM/FM stations/operators may use either a transmit system certified by its manufacturer under Part 15, or one of their own design and construction.
But in all cases, such operators are responsible to meet Part 15 in the operation of such stations.
