   (a) The definitions of terms used in part 97 are:

   (1) Amateur operator. A person named in an amateur operator/primary license
   station grant on the ULS consolidated licensee database to be the control
   operator of an amateur station.

   (2) Amateur radio services. The amateur service, the amateur-satellite
   service and the radio amateur civil emergency service.

   (4)  Amateur  service. A radiocommunication service for the purpose of
   self-training, intercommunication and technical investigations carried out
   by amateurs, that is, duly authorized persons interested in radio technique
   solely with a personal aim and without pecuniary interest.

   (5) Amateur station. A station in an amateur radio service consisting of the
   apparatus necessary for carrying on radiocommunications.

   (6) Automatic control. The use of devices and procedures for control of a
   station when it is transmitting so that compliance with the FCC Rules is
   achieved without the control operator being present at a control point.

   (7)  Auxiliary  station.  An  amateur station, other than in a message
   forwarding system, that is transmitting communications point-to-point within
   a system of cooperating amateur stations.

   (8) Bandwidth. The width of a frequency band outside of which the mean power
   of the transmitted signal is attenuated at least 26 dB below the mean power
   of the transmitted signal within the band.

   (9) Beacon. An amateur station transmitting communications for the purposes
   of observation of propagation and reception or other related experimental
   activities.

   (10) Broadcasting. Transmissions intended for reception by the general
   public, either direct or relayed.

   (11) Call sign system. The method used to select a call sign for amateur
   station over-the-air identification purposes. The call sign systems are:

   (i) Sequential call sign system. The call sign is selected by the FCC from
   an  alphabetized  list  corresponding  to the geographic region of the
   licensee's mailing address and operator class. The call sign is shown on the
   license. The FCC will issue public announcements detailing the procedures of
   the sequential call sign system.

   (ii) Vanity call sign system. The call sign is selected by the FCC from a
   list of call signs requested by the licensee. The call sign is shown on the

   (iii) Special event call sign system. The call sign is selected by the
   station licensee from a list of call signs shown on a common data base
   coordinated, maintained and disseminated by the amateur station special
   event call sign data base coordinators. The call sign must have the single
   letter prefix K, N or W, followed by a single numeral 0 through 9, followed
   by a single letter A through W or Y or Z (for example K1A). The special
   event  call sign is substituted for the call sign shown on the station
   license grant while the station is transmitting. The FCC will issue public

   system.
