Sec.  2.302   Call signs.

   The table which follows indicates the composition and blocks of
   international call signs available for assignment when such call signs are
   required by the rules pertaining to particular classes of stations. When
   stations operating in two or more classes are authorized to the same
   licensee for the same location, the Commission may elect to assign a
   separate call sign to each station in a different class. (In addition to the
   U.S. call sign allocations listed below, call sign blocks AAA through AEZ
   and ALA through ALZ have been assigned to the Department of the Army; call
   sign block AFA through AKZ has been assigned to the Department of the Air
   Force; and call sign block NAA through NZZ has been assigned jointly to the
   Department of the Navy and the U.S. Coast. Guard.
