   (a)(1) Except as provided in paragraph (a)(2) of this section, base and
   fixed  stations  may not be located within 150 km of any grandfathered
   satellite earth station operating in the 3650–3700 MHz band. The coordinates
   of these stations are available at http://www.fcc.gov/ib/sd/3650/. 

   (2) Base and fixed stations may be located within 150 km of a grandfathered
   satellite earth station provided that the licensee of the satellite earth
   station and the 3650–3700 MHz licensee mutually agree on such operation.

   (3) Any negotiations to enable base or fixed station operations closer than
   150 km to grandfathered satellite earth stations must be conducted in good
   faith by all parties.

   (b) (1) Except as specified in paragraph (b)(2) of this section, base and
   fixed stations may not be located within 80 km of the following Federal
   Government radiolocation facilities:

   Note:  Licensees installing equipment in the 3650–3700 MHz band should
   determine if there are any nearby Federal Government radar systems that
   could  affect their operations. Information regarding the location and
   operational characteristics of the radar systems operating adjacent to this
   band are provided in NTIA TR–99–361.

   (2) Requests for base or fixed station locations closer than 80 km to the
