§  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                 ^1 20
   5,925 to 6,425                 ^1 30
   6,425 to 6,525                    25
   10,700 to 12,200             ^1 2 40
   13,200 to 13,250                  25
   21,200 to 23,600               ^1 50

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

   ^2 As 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.
