It is the purpose of this chapter, among other things, to
maintain the control of the United States over all the channels of
radio transmission; and to provide for the use of such channels,
but not the ownership thereof, by persons for limited periods of
time, under licenses granted by Federal authority, and no such
license shall be construed to create any right, beyond the terms,
conditions, and periods of the license. No person shall use or
operate any apparatus for the transmission of energy or
communications or signals by radio (a) from one place in any State,
Territory, or possession of the United States or in the District of
Columbia to another place in the same State, Territory, possession,
or District; or (b) from any State, Territory, or possession of the
United States, or from the District of Columbia to any other State,
Territory, or possession of the United States; or (c) from any
place in any State, Territory, or possession of the United States,
or in the District of Columbia, to any place in any foreign country
or to any vessel; or (d) within any State when the effects of such
use extend beyond the borders of said State, or when interference
is caused by such use or operation with the transmission of such
energy, communications, or signals from within said State to any
place beyond its borders, or from any place beyond its borders to
any place within said State, or with the transmission or reception
of such energy, communications, or signals from and/or to places
beyond the borders of said State; or (e) upon any vessel or
aircraft of the United States (except as provided in section 303(t)
of this title); or (f) upon any other mobile stations within the
jurisdiction of the United States, except under and in accordance
with this chapter and with a license in that behalf granted under
the provisions of this chapter.
