    Authorized bandwidth. The occupied or necessary bandwidth, whichever 
is greater, authorized to be used by a station.
    Automatic relay station. A remote pickup broadcast base station 
which is actuated by automatic means and is used to relay transmissions 
between remote pickup broadcast base and mobile stations, between remote 
pickup broadcast mobile stations and from remote pickup broadcast mobile 
stations to broadcasting stations. (Automatic operation is not operation 
by remote control.)
    Carrier power. The average power at the output terminals of a 
transmitter (other than a transmitter having a suppressed, reduced or 
controlled carrier) during one radio frequency cycle under conditions of 
no modulation.
    Mean power. The power at the output terminals of a transmitter 
during normal operation, averaged over a time sufficiently long compared 
with the period of the lowest frequency encountered in the modulation. A 
time of 1/10 second during which the mean power is greatest will be 
selected normally.
    Necessary bandwidth. For a given class of emission, the minimum 
value of the occupied bandwidth sufficient to ensure the transmission of 
information at the rate and with the quality required for the system 
employed, under specified conditions. Emissions useful for the good 
functioning of the receiving equipment, as for example, the emission 
corresponding to the carrier of reduced carrier systems, shall be 
included in the necessary bandwidth.
    Occupied bandwidth. The frequency bandwidth such that, below its 
lower and above its upper frequency limits, the mean powers radiated are 
each equal to 0.5 percent of the total mean power radiated by a given 
emission.
    Operational communications. Communications concerning the technical 
and programming operation of a broadcast station and its auxiliaries.
    Remote control operation. Operation of a base station by a properly 
designated person on duty at a control position from which the 
transmitter is not visible but that position is equipped with suitable 
controls so that essential functions can be performed therefrom.
    Remote pickup broadcast base station. A remote pickup broadcast 
station authorized for operation at a specified location.
    Remote pickup broadcast mobile station. A remote pickup broadcast 
station authorized for use while in motion or during halts at 
unspecified locations. (As used in this subpart, mobile stations include 
hand-carried, pack-carried and other portable transmitters.)
    Remote pickup broadcast stations. A term used in this subpart to 
include both remote pickup broadcast base stations and remote pickup 
broadcast mobile stations.
    Remote pickup mobile repeater unit. A vehicular receiver-transmitter 
repeater used to provide extended communications range for a low-power 
hand-carried or pack-carried transmitter.
    Station. As used in this subpart, each remote pickup broadcast 
transmitter, and its associated accessory equipment necessary to the 
radio communication function, constitutes a separate station.
    Studio. Any room or series of rooms equipped for the regular 
production of broadcast programs of various kinds. A broadcasting booth 
at a stadium, convention hall, church, or other similar place is not 
considered to be a studio.
    Systems. A complete remote pickup broadcast facility consisting of 
one or more mobile stations and/or one or more base stations authorized 
pursuant to a single license.
