  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:
   Type of emission Authorized 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 Authorized
   Frequency band (MHz) Bandwidth (MHz)
   3,700 to 4,200                  ^120
   5,925 to 6,425                  ^130
   6,425 to 6,525                    25
   10,700 to 12,200              ^1,240
   13,200 to 13,250                  25
   21,200 to 23,600                ^150

   ^1The  maximum  bandwidth  that will be authorized for each particular
   frequency in this band is detailed in the appropriate frequency table in
    Sec. 101.147.

   ^2As  of  March 1, 2005, no new LTTS operators will be licensed in the
   11.7–12.2 GHz band. LTTS operators authorized prior to March 1, 2005 may
   continue to operate in 11.7–12.2 GHz band until their license expires; no
   existing LTTS licensees will be renewed in the 11.7–12.2 GHz band.

   (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.
