Sec.  23.13   Types of emission.

   

   Stations in the international fixed public radiocommunication services
   may  be authorized to use any of the types of emission or combinations
   thereof,  described  in  part  2 of this chapter, as well as new types
   which  may  be  developed:  Provided,  That  harmful  interference  to
   adjacent  operations is not caused thereby, And provided further, That
   the intelligence to be transmitted will use the bandwidth requested to
   a degree of efficiency compatible with the current state of the art. A
   determination  of  the  possibilities  of interference will be made as
   outlined  in  Sec. 23.20. In certain cases frequencies or emissions may be
   authorized  on  a  temporary  basis  to determine if interference will
   occur.  During normal operations, emissions shall be centered about an
   assigned  frequency.  Non-centered emissions may be employed for short
   periods  of  time  as  needed  to  avoid  interfering  signals or meet
   fluctuating  traffic loading: Provided, That the occupied bandwidth of
   these  emissions  be  contained  within  the authorized bandwidth, And
   provided  further,  That  prior  to  any  such  use, the Commission be
   notified of the reference frequency or frequencies proposed to be used
   in lieu of the assigned frequency.
