It uses five shared VHF channels, and MURS transmitter output is limited to 2 watts under normal operating conditions. Those limits define the service; they do not guarantee a particular communication range.
What does MURS stand for?
MURS stands for Multi-Use Radio Service. The FCC defines it in 47 CFR § 95.2703 as “A two-way, short distance voice or data communication service for facilitating personal or business activities of the general public.” The definition and service rules are in Part 95, Subpart J of the FCC regulations. FCC Part 95 rule amendments (2017)

The FCC’s earlier 2000 description also referred to image communications. Current rules permit voice, data, or image signals, as well as telecommand and telemetry. MURS is therefore not limited to ordinary voice conversations, even though two-way voice is its most familiar use. FCC 00-235 (2000)
What frequencies does MURS use?
MURS uses five shared VHF channels. Users share these frequencies rather than receiving an individually assigned channel:
#1 Best Overall
- MURS radios; RT27V can communicate directly with most brands of MURS radios; if you can't communicate after trying; you can contact us through Amazon email; we provide free firmware
- Commercial walkie talkie; suitable for long distance transmission in open areas; such as farms; logistics transportation; road and bridge construction; rescue organizations and other environments
- The antenna is upgraded; the new version of the antenna is lengthened by 6.5mm; the urban calling distance is extended by 300m
- Detachable antenna two way radios; you can replace high gain antenna or car antenna if you want to get longer transmission distance; very convenient for outdoor work
- Secure walkie-talkies; 5 low traffic channels; 50 CTCSS 105DCS; creates a quiet and secure communication environment
- 151.820 MHz
- 151.880 MHz
- 151.940 MHz
- 154.570 MHz
- 154.600 MHz

What are the main MURS operating rules?
Power and range
A MURS transmitter may not exceed 2 watts output under normal operating conditions. This is a transmitter-power ceiling, not a coverage-distance specification: the regulations do not promise a particular range, and the power limit alone cannot establish how far a given radio will communicate. The limit is set out in 47 CFR § 95.2767. 47 CFR Part 95 (2024 edition)
Rank #2
- MURS radios; RT27V can communicate directly with most brands of MURS radios; if you can't communicate after trying; you can contact us through Amazon email; we provide free firmware
- The antenna is updated; the new antenna is lengthened by 6.5mm; the call distance in the urban area is improved
- The signal wavelength of MURS walkie talkie is longer; it can propagate longer distances; it is suitable for use in outdoor open areas; such as fishing; boating; camping; road cycling
- Sealed design;RT27V walkie talkie is resistant to minor splashes and light rain; suitable for outdoor skiing; hiking; camping; off-roading; boating; hunting and other outdoor activities
- Low-traffic; MURS 5 channels; MURS channels are less crowded than other radios;you and your partner can have a better call experience
Equipment certification
MURS transmitter types must be certified for the service under Subpart J and Part 2. A programmable VHF radio is not automatically a legal MURS radio simply because it can be set to one of the five frequencies; check that the transmitter is FCC-certified for MURS. FCC Part 95 rule amendments (2017)
Repeaters, boosters, and packet operation
Repeaters and signal boosters are prohibited for MURS, including store-and-forward packet operation. Users cannot use those systems to retransmit or boost MURS signals to extend coverage. FCC Part 95 rule amendments (2017)

- Channel Announcement with Voice Alias - Leave radio on belt and know exactly what channel you are communicating on. Customize list of channels by selecting from 16 pre-recorded work functions, such as security, customer service, cashier, etc.
- Rugged design meets military specifications for sealing against dust, wind, shock, vibration and other adverse conditions. Radios also undergo Motorola's exclusive Accelerated Life Testing (ALT) that simulates up to 5 years of field use
- Advanced Voice Activation (VOX) - Enables hands-free operation with or without use of optional accessories.
Antennas and aircraft
For a fixed installation, the highest point of the antenna may be no more than 18.3 m (60 ft) above ground, or 6.10 m (20 ft) above the highest point of the supporting structure. Separate aviation-safety requirements also apply to antenna siting. MURS operation is not authorized aboard aircraft in flight. These limits are specified in the FCC’s Subpart J rules. FCC Part 95 rule amendments (2017)
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Is MURS just another name for a VHF radio?
No. MURS is a defined radio service, not a generic label for handheld VHF equipment. A radio must meet the applicable MURS equipment rules and carry the required FCC certification for its transmitter type; frequency capability or a seller’s description alone does not establish compliance.
