Yes.
§ 95.2703 Definitions, MURS.
MURS. A two-way, short distance voice or data communication service for facilitating personal or business activities of the general public.
Users/radios do not need to be registered. Radios, however, -must- have FCC Part 95J approval, which is not very common. You'll need to be using specific MURS radios to be legal.
§ 95.305 Authorization to operate Personal Radio Services stations
Pursuant to
47 U.S.C. 307(e)(1), this rule section authorizes eligible persons to operate part 95 Personal Radio Service stations and part 96 Citizens Broadband Radio Service stations without individual licenses, except as provided in paragraph (a). Such operation must comply with all applicable rules in this part.
(a)
Individual licenses. A valid individual license may be required under this part to operate or use stations in a particular service, certain types of stations, stations transmitting on certain channels or frequency bands, or stations transmitting with power above a certain level. Any such requirements applicable to stations in any of the Personal Radio Services are set forth in the subpart governing that specific service.
See e.g., § 95.1705. Otherwise, the FCC does not require or accept applications for an individual license to operate any type of Personal Radio Service station.
(b)
Operator eligibility. Some of the Personal Radio Services have specific operator eligibility requirements, which are set forth in the subparts governing those services. Otherwise, any person is eligible to operate a Personal Radio Service station, except as stated in
paragraphs (c) and
(d) of this section.
Someone will probably bring this up, and it's good to consider:
MURS is monitored by a lot of hobbyists. There are also a lot of legal users of MURS. MURS is limited to those 5 channels, so common to need to share channels with other users.
Consider the type of traffic you'll be passing over the radio and if a radio service that is wide open to the world is suitable. Consider privacy of students and security.
But, yes, totally legal to use.
