MURS is another ‘licensed by rule” service which does not require an operator to have a license. The FCC rules for MURS are contained in 47 CFR Part 95 Subpart J.
Permissible Uses
The operator of a MURS station may use it for the purposes listed in this section (§95.2731).
(a) MURS stations may be used to transmit voice, data or image signals.
(b) MURS stations may be used for telecommand and telemetry functions.
Prohibited Uses
MURS stations must not be operated as repeater stations or signal boosters. This prohibition includes store-and-forward packet operation. (§95.2733).
Transmitter Certification
Radios for use on the MURS frequencies must be certified in accordance with §95.2761, which states:
(a) Each MURS transmitter (a transmitter that operates or is intended to operate in MURS) must be certified in accordance with this subpart and part 2 of this chapter.
(b) A grant of equipment certification will not be issued for any MURS transmitter type that fails to comply with all of the applicable rules in this subpart.
(c) A grant of equipment certification will not be issued for MURS transmitters capable of operating under both this subpart (MURS) and under any other subparts of this chapter (except part 15).
This means that radios capable of transmitting on FRS/GMRS and MURS frequencies are allow (i.e., Baofeng and similar radios).
MURS Channels
MURS frequencies do not have a designated channel number, like FRS and GMRS, however the FCC does refer to them as ‘channels’ in §95.2763. The channels are identified by their center frequency as in the table below.
Under the AmRRON Channel 3 Project 151.940 MHz in the MURS frequency.
Power Limits
Power limits are listed in §95.2767 and summarized in the table below.
Bandwidth
Bandwidth is specified in §95.2773 and summarized in the table below.
| Frequency | Power | Bandwidth |
| 151.820 | 2 watts | 11.25 kHz |
| 151.880 | 2 watts | 11.25 kHz |
| 151.940 | 2 watts | 11.25 kHz |
| 154.570 | 2 watts | 20.0 kHz |
| 154.600 | 2 watts | 20.0 kHz |
Repeaters
Repeaters are not allowed on the MURS frequencies.
Communications Plan
Using MURS frequencies, as well as other Personal Radio Services frequencies, in your Communications Plan allows you to diversify your use of the radio spectrum. It does give you more frequencies over which to spread your communications and thereby providing some security through obscurity.
