§  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.
