Sec. 80.205  Bandwidths.

    (a) An emission designator shows the necessary bandwidth for each 
class of emission of a station except that in ship earth stations it 
shows the occupied or necessary bandwidth, whichever is greater. The 
following table gives the class of emission and corresponding emission 
designator and authorized bandwidth:
