Our Mission

The Arizona GMRS Repeater Club's Emergency Services Group strives to enhance the communications capabilities of anyone in need of reliable and consistent communications services in the event of catastrophic failure of systems and structure. We accomplish this by providing personnel to serve as auxiliary communications operators, who may be activated to provide communications and assistance to those in need in and around the Maricopa County area.
Emergency Services Group

AGRC Emergency Services Group

One of our primary goals is to support public safety agencies during a major emergency. We will work in cooperation with public and private organizations, including emergency management, police, fire, EMS, and CERT Teams. We will provide the assistance using our communications equipment or in other ways, as needed.

An additional mission is to assist the public in communicating with emergency services when normal, day to day, methods of contact are inoperative or overloaded. The public telephone system and the cell phone systems are a combined intersystem and rely on established infrastructure. There have been many instances in which this infrastructure has been damaged by natural disasters, by error, or in some cases, by intentional action. Following our emergency procedures and in cooperation with other agencies, we intend to provide a vital alternate link to 911 call centers or police and fire departments, when needed by the public.

The AGRC also provides resources to educate and inform the public about emergency communications and the use of alternate methods to contact emergency services.

Although our organization, the AGRC, is primarily for GMRS two-way radio operations, we are, in fact, a hybrid of GMRS and Amateur (Ham) radio operators. Many of our members are both licensed GMRS and Ham radio operators. This allows us to use the capabilities of both radio services, as needed.


ESG Capabilities

Those with training and experience in the military, law enforcement, fire/EMS, search and rescue, or CERT, including those who are retired, are encouraged to use their skills in the ESG. Currently, there are those with this type of experience and training in the ESG and more are welcome.

Members should provide information on their previous training, which will be included in their training record and updated with additional training. There are minimum training requirements in Incident Command System basics and communications, which include online FEMA Training courses: IS-100, IS-200, IS-700, IS-800.

Additional training will also be provided in communications, net operations and other subjects, as it becomes available.

Valley-Wide  Repeater Coverage

The club maintains a GMRS repeater on the White Tanks mountains with an elevation of about 4000' ASL which dominates a vast majority of the metro area and other parts of the county. Additionally, several members of AGRC have established repeaters around the valley, and have volunteered them for emergency useage as well, however, these ancilary repeaters do not utilize a specific emergency CTCSS tone as does the 550 machine does.e .





The ESG maintains a uniform and standardized channel plan that includes simplex frequencies for tactical and talk around use, which is in   compliance with APCO Project 25 standards. All ESG team members are required to maintain this channel map in all radios utilized for ESG activities


GIS Stuffs Basic GIS systems are in place, many of which are rudimentary programs such as USB GPS devices attached to laptop computers running over the counter programs such as Google Earth Pro, Microsoft Maps, Delorme Street Atlas and others. Not all ESG team members carry  this functionality, and it`s availability as a resource cannot be guaranteed.





The ESG team member is required to maintain current training in various ICS/NIMS courses such as IS-100, 200, 700 and 800. Regular training and exercises that conform to this structure are conducted, and ESG team membmers are required to attend on a regular basis.





Several ESG team members maintain additional equipment, such as solar, generators, and the like. This equipment is listed, but not always available. Situational dependency and mission requirements outline what is needed and from there, resource availability can be determined.




Emergency communications is an area with a challenging environment and unique situations for radio operators to volunteer in public service. We act as a trained reserve that activates when we are called. It is not just a hobby, it is a relevant activity. The ESG involves not only one organization, but working and being involved with many others, as well. If you would like to apply your abilities, increase your knowledge and use your communication skills in an organized team effort, then ESG may be for you.
