§ 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)
F3E or (G3E) 40
(d) Maximum bandwidths in the following frequency bands must not exceed
the limits set forth below:
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 § 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
(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.
