Sec.  74.401   Definitions.

   Associated broadcasting station ( s ). The broadcasting station or stations
   with which a remote pickup broadcast station or system is licensed as an
   auxiliary and with which it is principally used.

   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.
