Default The Great Unofficial Radioreference FRS/GMRS/MURS All-Inclusive Fact Sheet v2.0

Since the old "Fact Sheet" sticky post was a bit out of date I updated the previous content originally written by Darth_vader and reposted it here. I very likely have missed something or have a few typos so please feel free to suggest any edits!

DISCLAIMER: This document is for general informational purposes only. It is not intended as legal advice and should not be construed as such. Legal matters should be referred to a qualified attorney or lawyer. All information is considered current as of the date this post was submitted. Since regulations and practices may change over time, it is advisable to consult an official source such as the FCC for the most up-to-date information.

========== BANDWIDTH ==========

FRS (all channels)
Bandwidth: 12.5 kHz

GMRS
Bandwidth: 25 kHz (Ch 1-7, 15-22)
Bandwidth: 12.5 kHz (Ch 8-14)


========== LICENSING ==========

GMRS
License is required when operating at power levels greater than 2 watts ERP on channels 1-7 and 15-22, or when accessing repeaters.

At the time of this writing, GMRS licensing is handled by the FCC. The fee is $70 and the license is valid for 10 years. A GMRS license covers the holder and the immediate members of his/her family. A GMRS license holder must be aged 18 and up, but the service may be used by his family members of any age. No examination or test/quiz is conducted for GMRS licensing. A part 90/business or HAM radio license does NOT legally grant any privileges to operate GMRS and vice versa.

FRS
No license required when operating type-approved FRS radio within the FRS power limits (2 watts on channels 1-7 & 15-22, 0.5 watts on channels 8-14)

MURS
No license required when operating within MURS power limits (2 watts).


========== TYPE ACCEPTANCE ==========

//TODO: re-write this




========== FINDING TYPE-ACCEPTED TRANSCEIVERS FOR PART-95 USE ==========

The FCC maintain a searchable database of all transceivers certified for part-95 use on
https://apps.fcc.gov/oetcf/eas/repor...ericSearch.cfm

1. Under "Application Information: Application Status:", select Grant Issued.
2. Under "Equipment Information: Rule Parts (up to three):", select "95E" for GMRS, "95B" for FRS or "95J" for MURS and tick "exact match" (selected by default). It's probably best to search each one individually, as this narrows your search and reduces confusion.
3. Under "Formatting Options: Show results in", select "HTML" (default).
4. Specify number of search results to display (default: 10).
5. Select "Start search". It may take several minutes to display if a large number of results is given in step 4.

NOSCRIPT USERS: Temporarily allow "apps.fcc.gov" to use the search page.


========== REPEATERS ==========

Repeaters on GMRS are usually considered to be specifically for the private use of those who operate them, however many individuals and radio clubs operate "open" repeaters intended for public use. Some of these repeaters may require permission from the operators to work them, but not always (although it is considered polite to ask regardless.) A good resource for GMRS repeater information, including non-exhaustive lists of repeaters around the United States is myGMRS.com - GMRS Repeater Directory.


========== OTHER FACTS ==========

//TODO: update this?

FCC RULES
FRS: 47 CFR 95B
GMRS: 47 CFR 95E
MURS: 47 CFR 95J

FRS and GMRS always use FM. MURS may use other modulation formats, but FM is arguably the most commonly used.

GMRS channels 19 and 21 (650 and 700) are not allowed to be used near the Canadian border.

FRS transceivers are allowed to be used in Mexico on channels 1-14, however care must be exercised to avoid transmitting on GMRS 15-22 if a combination transceiver is used there.

It is legal for FRS and GMRS users to communicate with each other. The low maximum power level of FRS devices may cause problems when communicating to a GMRS station over any significant distance.

CTCSS and digital squelch is allowed on all services, and may be required to access repeaters on GMRS.

FRS, GMRS and MURS were originally intended to be used for personal communications within one's group, however there is almost nothing prohibiting deviation from this (see next paragraph). There is no "content police" on F/GM/MURS and in some areas, portions of GMRS and MURS are used as an "alternative" HAM service; the subject matter discussed in them might be similar to what one would find scanning the several HAM bands.

Transmission of music is never allowed on any part-95 band including CB. Morse code is allowed but rarely used for anything other than distress signals or automatic GMRS repeater self-identification. Data transmissions are allowed on MURS but may be restricted on the other services.

Business use of GMRS is generally prohibited, principally due to (expensive) licensing restrictions and its reclassification as a personal-use radio service in the 1980s. Exceptions exist for businesses licensed for GMRS before revision of the service's rule in the 1980s and are operating under the "grandfather" regulation. Many businesses are now using FRS for this purpose as it is free of such restrictions.

Several of your links are mangled or point to nonexistent web sites.

Welp..I realized that the comments can't be edited after two hours, so I'm unable to complete the updated Fact Sheet. Mods - can this post please be unstickied/deleted? I will then make a new post that includes all the intended revisions I was not able to include in this thread.

Or, abandon this idea of building the fact sheet as a forum message and make it a Wiki article instead. You won't have the editing restrictions in the Wiki that you have in the Forums.
