Sec. 78.104  Authorized bandwidth and emission designator.

    (a) The authorized bandwidth permitted to be used by a CARS station

    (b) As an exception to the provision of paragraph (a) of this

bandwidth where a persuasive showing is made that:
    (1) The frequency stability of the transmitting equipment to be used 
will permit compliance with Sec. 78.103(b)(1) and, additionally, will 
permit 99 percent of the total radiated power to be kept within the 
frequency limits of the assigned channel.
    (c) The emission designator shall be specified in terms of the 
necessary bandwidth. (See Sec. 2.201(a) of this chapter.)
