Multi-Use Radio Service (MURS) is a short-range, two-way, [[VHF]] radio service for free public use. It is not particularly popular, so it is relatively private.

==Range==

MURS range will vary depending on antenna size and placement.  With an external antenna, ranges of 10 miles or more can be expected however full [[Radio_Propagation|line-of-sight propagation]] is usually not possible due to the relatively low power restriction of 2 watts and even with proper equipment 10 mile ranges are generally not possible.  In general use with hand held radios that do not use additional external antennas MURS radios, base stations and [[motion detectors]] have typical [[walkie talkie]] ranges of about 1-2 miles.  If you are going to rely on MURS equipment it should like all equipment be tested on the ground prior to any disaster or emergency use.

Channels 1-3 use "narrowband" [[Frequency modulation|Frequency Modulation]] (2.5kHz deviation). Channels 4 and 5 use "wideband" FM (5 kHz deviation). MURS falls under part 95 and is not mandated for narrow banding such as those of part 90 in the public service bands by January 2013.

Because previous business band licensees who have maintained their active license remain grandfathered with their existing operating privileges, it is possible to find repeaters or other operations not authorized by Part 95 taking place. These are not necessarily illegal. If legal, such operations may enjoy primary status on their licensed frequency and as such are legally protected from harmful interference by MURS users.
