Rules, Information and Expectations


When you use a Mazama GMRS Repeater Group repeater, please operate within the following rules:

  • Wait for emergency radio messages/conversations to complete before transmitting.

  • Identify radio transmissions with our FCC assigned call letters at intervals as required by FCC rules. If you are a visitor or new local user, please say your call sign at the beginning of the conversation and then again at the end.  In the unlikely event that start to finish is longer than 15 minutes, then every 15 minutes during your conversation.  Remember even if you don't hear traffic, it doesn't mean that the repeater is not being used. (Listen in carrier squelch if in doubt.)

  • If you must call someone during a conversation then wait for the Courtesy Tone and then transmit saying "Break", or "Break, Break".  Those currently using the repeater should immediately yeild to your request to break in to make a call.

  • Monitor radio channels before transmitting to avoid interfering with users of the same channel. If you are listening with CTCSS squelch on your radio, switch it to carrier squelch or "monitor" first to be sure no one else is on the repeater.

  • Extend courteous behavior to other licensees using the GMRS.

  • Please read and follow the FCC Rules and Regulations governing the General Mobile and Family Radio Service.

  • We coordinate repeater operations including input and output tones to prevent mutual interference.  This is why it is important to listen in carrier squelch before transmitting initially.

  • Respect the property rights of others. We ask permission before using repeaters owned by other licensees. We recognize that other licensees are not required to share their repeaters with anyone. GMRS repeaters are private property. Owning a radio capable of repeater operation does not mean we can use any repeater we hear.  We are one is one of few repeater groups that allows use without permission when traffic is infrequent or irregular.  If you wish to become a regular, then we suggest you support our not inexpensive communications efforts.

  • Respect the rights of repeater owners to participate in the Open Repeater Initiative.

  • Please observe and comply with the operating requirements defined by the repeater group or the owner/licensee of the repeater you use.

  • Whenever practical, we enable CTCSS 141.3 Hz on our repeater inputs during regular hours of operation to allow any licensee access to the repeater to report an emergency or seek traveling information. If this tone is unavailable we listen in open squelch to repeater outputs whenever possible. Persons traveling and using 141.3 on GMRS repeaters should always request permission to make a call for assistance.

  • We monitor our own repeater so that it does not cause harmful interference during a period of malfunction and so it can be shut down when malfunctioning or during an attack by unauthorized users. We do our best to manage our repeater systems so that the behavior of our users is consistent with the Code.

  • We acknowledge that GMRS was originally created as base-to-mobile, mobile-to-base, and portable-to-portable, directed-communication radio service. Base-to-base communication was once prohibited, but as of February 1999 the FCC restriction against base-to-base communication was lifted. Nevertheless, GMRS licensees engaged in base-to-base communication shall yield to mobile or portable communication.

  • We try keep radio transmissions on high-level repeaters short to prevent monopolization of a frequency pair over a wide area for extended periods.

  • We properly maintain a GMRS repeater so that it does not retransmit signals received from FRS radios operating on channels adjacent to the repeater input.

  • We respect the occasional public service operation by a local public service team. Some organizations of licensees maintain GMRS radio systems with a specific purpose of assisting public safety agencies and providing a SkyWarn service. GMRS licensees and their communities benefit from the service these organizations provide. Such activities should be kept brief and to the point. Operators should yield to regular GMRS traffic when emergencies are not present. Amateur Radio style network activity on GMRS is discouraged though we have Amateur Radio operators as members.

  • We identify, and report unlicensed users of GMRS to the local PRA GMRS Intruder Interference Committee. Persistent unlicensed use by pirates is reported to the FCC Enforcement Bureau.

  • We respect and comply with the orders of commercial antenna site owners that allow our user group or individuals site access for radio equipment and antennas.

  • We use standard commercial engineering practices when installing and operating GMRS radio systems, particularly systems located at commercial antenna sites. GMRS channels are located in-between commercial and public safety system channels. It is imperative that the equipment we use be maintained to commercial standard and efficiency in order to avoid improper operation and interference to other services.

  • We do not use an automatic Morse Code or voice only identifier when a repeater is not in actual use. ID'ers that identify as beacons do not respect repeater or simplex radio traffic sharing the same frequency. Use of the identifier during regular communication through the repeater is the preferred method of operating identifiers.

  • We NEVER operate GMRS or FRS transceivers in other countries unless permitted by that country's laws. Currently U.S. GMRS radios are not legal in any other country. U.S. Type Approved FRS radios are legal only in Canada. Only Canadian GMRS radios of limited power level are allowed in Canada.

  • GMRS repeater owners have the obligation to coordinate CTCSS and DPL tones in use on their systems. The last repeater owner to put a tone on a system changes the tone whenever a conflict arises. Tones are not left installed in a system to "hold the tone for future use." Tones cannot be reserved for users not eligible to license in GMRS e.g. public safety and disaster organizations. There shall be a current user for each activated repeater tone. If one system changes users, the date the tone was placed on the system is the date the newest licensee with that tone was placed on the system. Licensees are strongly encouraged to keep station records with this information.

  • We encourage users to have their radios programmed for simplex on the repeater output using their assigned tone with options for CTCSS decode active and disabled.  We suggest also an alternate GMRS channel for more private use and FRS common channels if your radio is 5 watts or less.  You may use up 12 channels on your radios but if you have then, it add more versatility to your radios.  (See sample chart)

  • We observe the prohibition of operating GMRS radios North of Line A near the Canadian border on specified GMRS channels.  Those repeater pairs are:  462.650 and 462.700 Mhz.

  • If you operate on a grandfathered GMRS business repeater and you do not hold your own GMRS license and are not eligible under the license of an immediate family member, you do not operate outside the license limitations of the grandfathered system.  You likely can't operate on our repeater(s).

  • We do not interfere with or annoy grandfathered business users licensed for GMRS channels. (None known in our service area)

  • We acknowledge that the FCC expects all licensees to cooperatively resolve operational complaints between GMRS systems.

  • We never operate modified Amateur Radio transceivers in the GMRS, FRS, or MURS.

  • We never camp on a frequency pair with the specific intent to busy out the channel in order to discourage others from using the frequencies or setting up another repeater. GMRS frequencies are a shared resource and licensees do not engage in hostile behaviors to warn others away.

  • We recognize there are incompatible uses of the GMRS. Any single grandfathered licensee or group of GMRS licensees that engages in network-style activity should consider licensing on a business radio frequency so GMRS channels are not monopolized by a single licensee, or organized group of licensees.

  • In the event my repeater is the victim of intentional interference neither I or my users will acknowledge or antagonize the responsible parties
