Sec. 95.637 Modulation
standards.
(a) A GMRS transmitter that transmits
emission types F1D, G1D, or
G3E must not exceed a peak frequency deviation
of plus or minus 5 kHz. A
GMRS transmitter that transmits emission type F3E
must not exceed a peak
frequency deviation of plus or minus 5 kHz. A FRS
unit that transmits
emission type F3E must not exceed a peak frequency
deviation of plus or
minus 2.5 kHz, and the audio frequency response must
not exceed 3.125
kHz .
(b) Each GMRS transmitter,
except a mobile station transmitter with
a power output of 2.5 W or less,
must automatically prevent a greater
than normal audio level from causing
overmodulation. The transmitter
also must include audio frequency low pass
filtering, unless it complies
with the applicable paragraphs of Sec. 95.631
(without filtering.) The
filter must be between the modulation limiter and
the modulated stage of
the transmitter. At any frequency (f in kHz) between
3 and 20 kHz, the
filter must have an attenuation of at least 60
log
greater than the attenuation at 1 kHz. Above 20
kHz, it must have an
attenuation of at least 50 dB greater than the
attenuation at 1 kHz.
(c) When emission type A3E is
transmitted, the modulation must be
greater than 85% but must not exceed
100%. Simultaneous amplitude
modulation and frequency or phase modulation of
a transmitter are not
permitted.
(d) When emission
type A3E is transmitted by a CB transmitter having
a TP of greater than 2.5
W, the CB transmitter must automatically
prevent the modulation from
exceeding 100%.
(e) Each CB transmitter that transmits
emission type H3E, J3E or R3E
must be capable of transmitting the upper
sideband. The capability of
also transmitting the lower sideband is
permitted.

(f) DSRCS-OBUs are governed under subpart L
of this part.
Sec. 95.639 Maximum transmitter
power.
(a) No GMRS transmitter, under any condition of
modulation, shall
exceed:
(1) 50 W Carrier power
(average TP during one unmodulated RF cycle)
when transmitting emission type
A1D, F1D, G1D, A3E, F3E or G3E.
(2) 50 W peak envelope TP
when transmitting emission type H1D, J1D,
R1D, H3E, J3E or
R3E.
(b) No R/C transmitter, under any condition of
modulation, shall
exceed a carrier power or peak envelope TP
(single-sideband only) of:
(1) 4 W in the 26-27 MHz
frequency band, except on channel frequency
27.255
MHz;
(2) 25 W on channel frequency 27.255
MHz;
(3) 0.75 W in the 72-76 MHz
frequency band.
(c) No CB transmitter, under any condition
of modulation, shall
exceed:
(1) 4 W Carrier power
when transmitting emission type A1D or A3E;
(2) 12 W peak
envelope TP when transmitting emission type H1D, J1D,
R1D, H3E, J3E or R3E.
Each CB transmitter which transmits emission type
H3E, J3E or R3E must
automatically prevent the TP from exceeding 12 W
peak envelope TP or the
manufacturer's rated peak envelope TP, whichever
is
less.
(d) No FRS unit, under any condition of modulation,
shall exceed
0.500 W effective radiated power (ERP).
(e) The maximum transmitter output power authorized for LPRS
stations is 100
mW.
(f) In the MICS the following limits
apply:
(1) The maximum EIRP for MICS transmitter stations
is 25 microwatts.
The antenna associated with any MICS transmitter must be
supplied with
the transmitter and shall be considered part of the
transmitter subject
to equipment authorization. Compliance of any MICS
transmitter with the
25 microwatts EIRP limit may be determined by measuring
the radiated
field from the equipment under test at 3 meters and calculating
the
EIRP. The equivalent radiated field strength at 3 meters for 25
microwatts EIRP is 18.2 mV/meter when measured on an open area test
site, or 9.1 mV/meter when measured on a test site equivalent to free
space such as a fully anechoic test chamber. In either case, compliance
is based on measurements using a peak detector function and measured
over an interval of time when transmission is continuous and at its
maximum power level. In lieu of using a peak detector function,
instrumentation techniques set forth in ANSI C63.17-1998, Section
6.1.2.2.1 or Section 6.1.2.2.2 may be used in determining compliance
with the above specifications.
(2) For a transmitter
intended to be implanted in a human body, the
following test fixture must be
used to simulate operation of the implant
under actual operating conditions.
See Sec. 95.605.
(i) For measurement purposes to determine
compliance with emission
limits, the radiating characteristics of an implant
transmitter placed
in a test fixture should approximate those of an implant
transmitter
placed in a human body. An appropriate human torso simulator for
testing
medical implant transmitters consists of a cylindrical Plexiglas
container with a size of 30 cm by 76 cm with a sidewall thickness of
0.635 cm. It must be completely filled with a material that is
sufficiently fluidic that it will flow around the implant without any
voids. The dielectric and conductivity properties of this material must
match the dielectric and conductivity properties of human muscle tissue
at 403.5 MHz. All emissions measurements will be made using the above
specification at a nominal temperature of 20-25[deg]C. Simple saline
solutions do not meet the above criteria. A mounting grid for the
implant inside the container must be provided that permits the radiating
element or elements of the implant to be positioned vertically and
horizontally. The grid should also support any additional implant leads
associated with the therapeutic function in a fixed repeatable manner.
The implant must be mounted 6 cm from the sidewall and centered
vertically within the container. The above fixture shall be placed on a
turntable such that the implant transmitter will be located at a nominal
1.5-meter height above ground and at a 3-meter distance from the
measurement antenna. Radiated emissions measurements shall then be
performed to insure compliance with the applicable technical
specifications.
(ii) A formula for a suitable tissue
substitute material is defined
in the paper ``Simulated Biological Materials
for Electromagnetic
Radiation Absorption Studies'' by G. Hartsgrove, A.
Kraszewski, and A.
Surowiec as published in ``Bioelectromagnetics 8:29-36
(1987)''.
(3) The power radiated in any 300 kHz bandwidth
shall not exceed 25
microwatts EIRP. See Sec. Sec. 95.633(e) and
95.639(g).
(g) The maximum field strength authorized for
WMTS stations in the
608-614 MHz band is 200 mV/m, measured at 3 meters. For
stations in the
1395-1400 MHz and 1427-1429.5 MHz
bands, the maximum field strength is 740 mV/m,
measured at 3
meters.
(h) No MURS unit, under any condition of
modulation, shall exceed 2
Watts transmitter power output.

accessibility.
(a) No control, switch or
other type of adjustment which, when
manipulated, can result in a violation
of the rules shall be accessible
from the transmitter operating panel or
from exterior of the transmitter
enclosure.
(b) An R/C
transmitter which incorporates plug-in frequency
determining modules which
