The primary role for both services is to support the emergency management community (responders, relief, and recovery agencies) with communications during times of emergency and disaster when normal communications are unavailable or overwhelmed with use. Amateur radio works when other methods fail as it does not rely on wires and communication facilities of common carriers. Amateurs have a wide range of frequencies and modes available to deliver routine, welfare, emergency and tactical messages. Amateur operators are licensed and authorized to communicate internationally into and out of places where disaster has struck. The radio services provide Herkimer County with a reserve of operators and technicians that are trained and equipped in the art of radio communications. For more detailed information about ARES and RACES see the ARRL Public Service Communications Manual.

Herkimer County ARES/RACES owns and maintains three Very High Frequency (VHF) repeaters. The N2ZWO/1 repeater is tuned to 145.110 MHz using a minus offset and a PL Tone of 167.9. This repeater is interfaced with a weather receiver that automatically broadcasts severe weather alerts for the local area when the alerts are issued by the National Weather Service Albany. Also, a telephone autopatch system is available on this repeater for authorized users. The repeater is located in southern Herkimer County. The second, N2ZWO/2 VHF repeater is tuned to 147.045. It uses a plus offset and a PL Tone of 167.9. It is located north of the Mohawk Valley. The third repeater, N2ZWO/3  is located at the 911 center in Herkimer. Each of the repeaters is provided with an emergency power source for use when commercial power fails. The repeaters have received frequency coordination through UNYREPCO.

Herkimer County ARES/RACES owns and maintains an Automatic Position Reporting System (APRS) wide area node N2ZWO-10. The APRS system includes the use of the Global Position System (GPS) satellites and a nationwide network of amateur VHF and HF radios, computers, and maps used to digitally transmit messages, weather events and real time positions. Also transmitted are the real time positions of people, vehicles, aircraft and satellites. Members of Herkimer County ARES/RACES own personal APRS equipment and actively participate in the network activities. An active APRS station is even included along with other amateur radio equipment aboard the International Space Station.

Installed at the Herkimer County Communications Center in the Office of Emergency Services is an all mode ARES/RACES communications station. This station includes VHF, UHF, and HF voice radios. A computer and VHF radio provide APRS and Packet radio communications. Included in the equipment are a Kenwood D700A, a Yaesu 920, and an Alinco DR140. Digital communications are also possible on VHF and HF frequencies using "Fldigi" software. Using Fldigi enables real time messaging using message formats from the Incident Command System and Red Cross.

Members of Herkimer County ARES/RACES actively train throughout the year. Training nets are held every Monday evening at 7:00 p.m. on the 145.110 MHz repeater. (Alternate frequencies are 147.090/ 147.045/ and 146.580 simplex.) The New York State RACES training net is held each Sunday morning at 9:00 a.m. on 3.993.5 mhz. The annual ARRL "Field Day" is held on the fourth weekend of June. During that weekend extensive training in setting up remote temporary communications stations is provided through a nationwide competition of ARES organizations. Each fall the annual Simulated Emergency Test (SET) is run to test the response readiness of ARES groups throughout the U.S. ARES/RACES members provide communications for various parades, bike and foot races, and at Halloween for the NY State Police "Pumpkin Patrol". During the patrol NY State Thruway Bridges are watched for any signs of mischief that might endanger travelers on the interstate highway. Each event provides further skill training for ARES/RACES personnel.

"SKYWARN" is a network of community weather spotters serving the National Weather Service. An important part of weather forecasting is the inclusion and use of data supplied by trained weather observers. Herkimer County ARES/RACES participates in the National Weather Service Skywarn program through the direction of the Albany Office of the NWS. Skywarn spotter training is provided annually by instructors from the Albany Office of the NWS. An amateur radio station is installed at the Albany forecast office. During severe weather events local Skywarn spotters are activated. Information concerning rainfall/snowfall amounts, wind speeds, hail size, storm damages, etc. are forwarded to the Albany meteorologists. Skywarn activities have become a very important part of ARES activities in the county.

Herkimer County ARES/RACES is officially an integral part of the Fort Herkimer Amateur Radio Association, Inc. The corporation attained 501(c)3 public charity status in March 2020. Meetings are held on the 2nd Wednesday of the month at the Herkimer County communications center.
