Sec.  90.249   Control stations.

   Control stations associated with land mobile stations under this part shall
   be authorized to operate subject to the following:

   (a) Frequencies for control stations. (1) Control stations may be authorized
   to operate on frequencies available for use by operational fixed stations.

   (2) A control station associated with mobile relay station(s) may, at the
   option of the applicant, be assigned the frequency of the associated mobile
   station. In the Industrial/Business Pool, on frequencies designated with an
   “LR” in the coordinator column of the frequency table in  Sec. 90.35(b)(3), such
   a control station may be assigned any mobile service station frequency
   available for assignment to mobile stations. Such operation is on a
   secondary basis to use of the frequency for regular mobile service
   communications.

   (3) Control and fixed stations in the Public Safety Pool may be authorized
   on a temporary basis to operate on frequencies available for base and mobile
   stations between 152 and 450 MHz, where there is an adequate showing that
   such operations cannot be conducted on frequencies allocated for assignment
   to operational fixed stations. Such operation will not be authorized
   initially or renewed for periods in excess of one year. Any such
   authorization shall be subject to immediate termination if harmful
   interference is caused to stations in the mobile service, or if the
   particular frequency is required for mobile service operations in the area
   concerned.

   (b) [Reserved]

   (c) A base station which is used intermittently as a control station for one
   or more associated mobile relay stations of the same licensee shall operate
   only on the mobile service frequency assigned to the associated mobile relay
   station when operating as a base station and on the mobile service frequency
   assigned to the associated mobile station when operating as a control
   station. Authority for such dual classification and use must be shown on the
   station authorization. When operating as a control station, the licensee
   must meet all control station requirements. In the Industrial/Business Pool,
   on frequencies designated with an “LR” in the coordinator column of the
   frequency table in  Sec. 90.35(b)(3), base stations used intermittently as
   control stations shall operate only on a mobile service frequency which is
   available for assignment to base stations.
