Sec. 101.809  Bandwidth and emission limitations.

    (a) Stations in this service operating on frequencies in the 27.23-
27.28 MHz band will be authorized to employ only amplitude modulated or 
frequency modulated emission for radiotelephony. The authorization to 
use such emissions will be construed to include authority to employ 
unmodulated emission only for temporary or short periods necessary for

equipment testing incident to the construction and maintenance of the 
station.
    (b) Stations in the service operating on frequencies above 940 MHz 
may be authorized to use amplitude modulated, frequency modulated or 
pulse type of emission for radiotelephony and television. In addition, 
the use of unmodulated emission may be authorized in appropriate cases.
    (c) The maximum bandwidths which will normally be authorized for 
single channel operation on frequencies below 500 MHz in this service 
must not exceed the limits set forth below:

------------------------------------------------------------------------
                                                           Authorized   
                   Type of emission                     bandwidth (kHz) 
------------------------------------------------------------------------
A3E..................................................                  8
F3E or (G3E).........................................                 40
------------------------------------------------------------------------

    (d) Maximum bandwidths in the following frequency bands must not 
exceed the limits set forth below:

------------------------------------------------------------------------
                                                            Maximum     
                 Frequency band (MHz)                      authorized   
                                                        bandwidth (MHz) 
------------------------------------------------------------------------
3,700 to 4,200.......................................                 20
5,925 to 6,425.......................................                 30
6,425 to 6,525.......................................                 25
10,700 to 12,200.....................................                 40
13,200 to 13,250.....................................                 25
22,000 to 23,600.....................................                100
------------------------------------------------------------------------

    (e) The bandwidths authorized on frequencies above 500 MHz must be 
appropriate to the type of operation in any particular case. An 
application requesting such authorization must fully describe the 
modulation, emission, and bandwidth desired and must specify the 
bandwidth to be occupied.
