Sec.  74.32   Operation in the 17.8–19.7 GHz band.

   (a) To minimize or avoid harmful interference to Government Satellite Earth
   Stations located in the Denver, Colorado and Washington, DC areas, any
   application for a new station license to operate in the 17.8–19.7 GHz band,
   or for modification of an existing station license in this band which would
   change the frequency, power, emission, modulation, polarization, antenna
   height or directivity, or location of such a station, must be coordinated
   with the Federal Government by the Commission before an authorization will
   be issued, if the station or proposed station is located in whole or in part
   within any of the areas defined by the following rectangles or circles:

   Denver, CO Area

   (b) Within a radius of 178 km of 38 °48'00" N. Lat./76 °52'00" W. Long.

   (c)  In  addition,  no application seeking authority to operate in the
   17.8–19.7 GHz band will be accepted for filing if the proposed station is
   located within 20 km of the following coordinates:
