Appendix G – FCC MURS Rules
For information on using the TS4000 under the FCC’s unlicensed MURS rules
see the Licensing – Unlicensed Operation section above.
Notes:
1) The rules for MURS first went into effect on November 13, 2000.
2) The FCC may change, add, restrict or modify these rules in the future.
3) A number of changes to the MURS rules were made in October of 2002.
The following is a copy of the FCC Rules that pertain to MURS operation.
FCC Rules – 2005 Code of the Federal Regulations Part 95 of Title 47
Revised as of October 1, 2005
95.401 (CB Rule 1) What are the Citizens Band Radio Services?
The Citizens Band Radio Services are:
* * * * *
(f) The Multi-Use Radio Service (MURS)--a private, two-way, short distance voice or
data communications service for personal or business activities of the general public.
The rules for this service are contained in subpart J of this part.
95.601 Basis and purpose.
* * * The Personal Radio Services are the GMRS (General Mobile Radio Service)-subpart A,
the Family Radio Service (FRS)-subpart B, the R/C(Radio Control Radio Service)-subpart C,
the CB (Citizens Band Radio Service)-subpart D, the Low Power Radio Service (LPRS)-subpart
G, the Wireless Medical Telemetry Service (WMTS)-subpart H, the Medical Implants
Communication Service (MICS)-subpart I, and the Multi-Use Radio Service (MURS)--subpart J.
95.603 Certification required.
(g) Each Multi-Use Radio Service transmitter (a transmitter that operates or is
intended to operate in the MURS) must be certificated in accordance with Subpart J of Part
2 of this chapter, Provided however, that those radio units certificated as of November
12, 2002 need not be recertificated.
95.605 Certification procedures.
Any entity may request certification for its transmitter when the transmitter is used
in the GMRS, FRS, R/C, CB, IVDS, LPRS, MURS, or MICS following the procedures in part 2 of
this chapter. * * *
95.631 Emission types.
(j) A MURS transmitter must transmit only A1D, A2B, A2D, A3E, F2B, F1D, F2D, F3E, G3E.
Emission types A3E, F3E and G3E include selective calling or tone-operated squelch tones
to establish or continue voice communications. MURS transmitters are prohibited from
transmitting in the continuous carrier mode.
95.632 MURS transmitter frequencies.
(a) The MURS transmitter channel frequencies are 151.820MHz, 151.880MHz, 151.940MHz,
154.570MHz, 154.600MHz.
(b) The authorized bandwidth is 11.25kHz on frequencies 151.820MHz, 151.880MHz and
151.940MHz. The authorized bandwidth is 20.0kHz on frequencies 154.570MHz and 154.600MHz.
(c) MURS transmitters must maintain a frequency stability of 5.0 ppm, or 2.0 ppm if
designed to operate with a 6.25kHz bandwidth.
95.633 Emission bandwidth.
(f) The authorized bandwidth for any emission type transmitted by a MURS transmitter
is specified as follows:
(1) Emissions on frequencies 151.820MHz, 151.880MHz and 151.940MHz are limited to
11.25KHz.
(2) Emissions on frequencies 154.570MHz and 154.600MHz are limited to 20.0KHz.
(3) Provided, however, that all A3E emissions are limited to 8KHz.
