For vehicle-to-vehicle operation with external (roof-mount) antennas, MURS should provide one-and-a-half to four times the range possible with GMRS handheld radios also connected to roof-mount antennas.

At MURS frequencies, signals bend over hills better, but GMRS signals are better at bouncing off of surfaces and penetrating into/escaping out of buildings.

GMRS operation requires an FCC license.

GMRS stations may transmit with no more the 5 Watts ERP on the seven “interstitial” frequencies (those shared with the FRS).

There is no limit on the ERP of GMRS stations operating on the primary channels. GMRS vehicular units transmit typically with ten to 50 watts.

GMRS handheld radios have typically two to five watts transmitter power.

For vehicle-to-vehicle operation with external (roof-mount) antennas, MURS should provide three to ten (or more) times the range possible with FRS radios.Ĭompared with GMRS (General Mobile Radio Service) at 460 MHz: FRS radios must employ a non-detachable antenna.

You may connect a MURS radio to an external or exterior antenna.

At MURS frequencies, signals bend over hills better, but FRS signals are better at bouncing off of surfaces and penetrating into/escaping out of buildings.

MURS (at 150 MHz) permits four times more power (2 Watts TPO instead the 0.500 Watts ERP limit for FRS).

Here are some great comparisons courtesy of PRSG.Ĭompared with FRS (Family Radio Service) at 460 MHz: Most everyone has seen the small hand-held walkie-talkies that operate on the FRS (Family Radio Service), the best example of this are the small Motorola Talkabout Radios marketed towards family communication.

While this is not encryption, anyone not operating with the same PL code won’t hear your conversation. There are 38 PL codes available to each of the five MURS frequencies, which makes for a combination of 190 different MURS channels. Can you hear me now?Īnother hidden benefit of MURS frequencies are the PL codes (Private Line codes) or CTCSS (Continuous Tone Coded Squelch System) which are sub-audible tones that allow users to operate on the same channel without hearing chatter directed to other users. The best example of this are the driveway alarms which transmit a signal via MURS when the IR sensor is tripped. The 151 MHz channels can only be operated in narrow band mode.Įach of the five frequencies can not only transmit voice, but also data. The five MURS frequencies are listed below, The 154 MHz channels can be operated on the standard 25 kHz wide band or narrow band mode. The stipulations for MURS use provided by the FCC restrict any transmitter in excess of two watts, but any type of antenna is allowed as long as the tower height (with antenna) is no greater than 60 feet high. All communications must also yield to any emergency communication on the same channel. What’s not to love about MURS? MURS stands for Multi User Radio Service, and is one of the best kept secrets in personal and family radio communications.įormerly available only for business communications, the FCC has kept five MURS frequencies license-free and open for public use since 2000. Handheld radios broadcasting on MURS frequencies can experience a range of two miles to eight miles depending on terrain and obstructions, while MURS Base Stations can reach up to 20 miles.
