Sec. 101.109  Bandwidth.

    (a) Each authorization issued pursuant to these rules will show, as 
the emission designator, a symbol representing the class of emission 
which must be prefixed by a number specifying the necessary bandwidth. 
This figure does not necessarily indicate the bandwidth actually 
occupied by the emission at any instant. In those cases where part 2 of 
this chapter does not provide a formula for the computation of the 
necessary bandwidth, the occupied bandwidth may be used in the emission 
designator.
    (b) Stations in this service will be authorized any type of 
emission, method of modulation, and transmission characteristic, 
consistent with efficient use of the spectrum and good engineering 
practice, except that Type B, damped-wave emission will not be 
authorized.
    (c) The maximum bandwidth which will be authorized per frequency 
assigned is set out in the table that follows. Regardless of the maximum 
authorized bandwidth specified for each frequency band, the Commission 
reserves the right to issue a license for less than the maximum 
bandwidth if it appears that a lesser bandwidth would be sufficient to 
support an applicant's intended communications.
