Although the FCC's Rules governing GMRS (in Title 47 of the Code of Federal Regulations, officially 47 CFR 95 Subpart A and portions of Subpart E) are available on the Web from several sources, including from the Government Printing Office itself, we have found that nowhere (yet, anyway) is available a downloadable compilation of all of the current GMRS-related rules in a single file. The viewable version below includes changes made in the ULS docket, including those adopted by the FCC's Memorandum Opinion and Order on Reconsideration in response to the PRSG Petition for Reconsideration.

A ZIP-compressed file containing the plain-ASCII version of the rules is also available for downloading by clicking here: download hot button

Please feel free to redistribute the PRSG version, although we would appreciate recognition of our effort to serve the GMRS user public. You should also warn others that these Rules do change occasionally. The PRSG will endeavor to keep the most recent version available on our Web site. (These changes sometimes occur in obscure and otherwise non-GMRS-related dockets!)

The PRSG version of the GMRS Rules differs from those available from several other sources in the following respects:

If you wish, you can also peruse the GMRS Rules here on this Web site. Below is the Table of Contents with links to the sections that follow. We also provide copious navigational links to make it easier for you:

In this on line version, we have retained the FCC's sometimes slavish emphasis of certain key words (mobile, radio, etc.) even in those places where the emphasis would seems unnecessary or inappropriate.

If you wish to understand more of the implications of the changes made to the GMRS Rules by the ULS Docket, you may also wish to view an earlier version of these Rules. This earlier version (dated June 11, 1999) is no longer current, but does include a discussion, rule part by rule part, of the changes adopted by the ULS Docket.

Also available on this Web site is the November 10, 1988 Report and Order in FCC Docket 87-265. This was the FCC action that established the current version of the GMRS Rules. (These FCC Rules have actually changed very little since then.)

The significance of this earlier R&O is that it explains in detail the FCC's rationale for the landmark changes adopted in this rulemaking docket. This R&O is available here as a 22 KB ZIP-compressed version (87265RO.ZIP) of an 70 KB straight ASCII text file. You can download this file by clicking here: download hot button

Some final notes: If you find errors in our version of these rules, please let us know. We are also considering including more cross references and possibly even interpretations. Please let us now if you would like these enhancements. You can send your comments and criticisms to the PRSG.

In addition, there are some sections of even the current FCC Rules that are out of date and in need of modification or deletion. On the PRSG Web site, we will post more information about plans to petition the FCC for these changes.

95.3 License required.

Before any station transmits on any channel authorized in the GMRS from any point (a geographical location) within or over the territorial limits of any area where radio services are regulated by the FCC, the responsible party must obtain a license (a written authorization from the FCC for a GMRS system).

Top of Page | Table of Contents | Rules Home Page | PRSG Home Page

95.5 License eligibility.

(a) An individual (one man or one woman) is eligible to obtain, renew and have modified a GMRS system license if that individual is 18 years of age or older and is not a representative of a foreign government.

(b) A non-individual (an entity other than an individual) is ineligible to obtain a new GMRS system license or make a major modification to an existing GMRS system license.

(c) A GMRS system licensed to a non-individual before July 31, 1987, is eligible to renew that licenses and all subsequent licenses based upon it if:

(1) The non-individual is a partnership and each partner is 18 years of age or older; a corporation; an association; a state, territorial, or local government unit; or a legal entity;

95.7 Channel sharing.

(a) Channels or channel pairs (one 462 MHz frequency listed in 95.29(a) of this part and one 467 MHz frequency listed in 95.29(b) of this part) are available to GMRS systems only on a shared basis and will not be assigned for the exclusive use of any licensee. All station operators and GMRS system licensees must cooperate in the selection and use of channels to reduce interference and to make the most effective use of the facilities.

(b) Licensees of GMRS systems suffering or causing harmful interference are expected to cooperate and resolve this problem by mutually satisfactory arrangements. If the licensees are unable to do so, the FCC may impose restrictions including specifying the transmitter power, antenna height, or area or hours of operation of the stations concerned. Further, the use of any frequency at a given geographical location may be denied when, in the judgment of the FCC, its use in that location is not in the public interest; the use of any channel or channel pair may be restricted as to specified geographical areas, maximum power, or other operating conditions (see 95.71(d)).

The transmitter also must include audio frequency low pass filtering, unless it complies with the applicable paragraphs of 95.631 (without filtering). The filter must be between the modulation limiter and the modulated stage of the transmitter. At any frequency (f in kHz) between 3 and 20 kHz, the filter must have an attenuation of at least 60 log10 (f/3) dB greater than the attenuation at 1 kHz. Above 20 kHz, it must have an attenuation of at least 50 dB greater than the attenuation at 1 kHz.
