In this section, “amateur radio” means the use of a radio frequency spectrum for purposes of noncommercial exchange of messages, wireless experimentation, self–training, private recreation, radiosport, contesting, or emergency communication by a duly authorized person interested in radioelectric practice with a purely personal aim and without pecuniary interest. This section applies to all counties and municipalities. It is the intent of the General Assembly to codify the provisions of 47 C.F.R. § 97.15 concerning the Federal Communications Commission’s preemption of local ordinances regulating amateur radio station antenna structures. A county or municipal ordinance regulating amateur radio station antenna structures: may not preclude amateur radio communications; shall reasonably accommodate amateur radio communications; and shall constitute the minimum practicable regulation to accomplish the legitimate purpose of the ordinance.
