Networking with Ham Groups via Ham Radio
Article 7 out of 10
In September 2017, as Hurricane Maria ravaged Puerto Rico and left much of the island without power or cellular service, amateur radio operators activated emergency nets to bridge the communication gap. The Hurricane Watch Net, operating on 14.325 MHz USB and 7.268 MHz LSB, relayed vital weather data and welfare messages to the National Hurricane Center and relief agencies, handling over 5,000 transmissions in the storm’s aftermath, according to ARRL reports from October 2017 ARRL reports on Hurricane Maria. Local ARES groups in the U.S. coordinated with Puerto Rican hams via Winlink and voice nets, facilitating supply requests and family reunifications when official channels were overwhelmed. This real-world activation underscores the power of organized ham radio networks in crises. For operators in areas like Caswell Beach, NC—prone to similar hurricanes—joining or forming such nets builds community resilience. This article outlines strategies for engaging with ham-based groups, from ARES and RACES involvement to frequency coordination. It includes tips on etiquette, drill scheduling, and scaling from local check-ins to national collaborations, all grounded in FCC regulations and ARRL best practices. Whether you’re a new Technician seeking local connections or an experienced Extra aiming to lead, these networks turn individual stations into coordinated assets.
Understanding Ham Radio Nets: The Foundation of Group Communications
A ham radio net is a scheduled gathering of operators on a specific frequency for structured exchanges, often focused on information sharing, training, or emergencies. Nets operate under FCC Part 97, which emphasizes public service and prohibits commercial use while requiring stations to identify every 10 minutes (§97.119) FCC §97.119. They range from informal ragchews to directed nets led by a Net Control Station (NCS) who manages traffic.
In emergencies, nets provide disciplined channels for relaying messages, avoiding the chaos of open frequencies. For instance, during the 2012 High Park Fire in Colorado, which burned 87,000 acres, ARES nets on local VHF repeaters (e.g., 145.145 MHz in Larimer County) coordinated evacuations and resource allocation, as noted in ARRL ARES reports from June 2012 ARRL on High Park Fire. Non-emergency nets build skills, like weekly check-ins that test propagation and gear.
Nets align with band plans from ARRL, which allocate segments for modes like SSB (e.g., 3.800-4.000 MHz on 80m) or FM simplex (146.520 MHz national calling) ARRL Band Plan. Coordination prevents interference, especially on shared resources like repeaters, which require tone access (e.g., CTCSS 100.0 Hz).
Joining Existing Ham Networks: ARES, RACES, and Beyond
The easiest entry is through established groups like the Amateur Radio Emergency Service (ARES) and Radio Amateur Civil Emergency Service (RACES). ARES, sponsored by ARRL, trains volunteers for public service; join via your local Emergency Coordinator (EC) at arrl.org/ares ARRL ARES. In North Carolina, the NC Section ARES handles activations, with weekly nets on repeaters like 146.640 MHz in Raleigh (PL 100.0 Hz) for training NC ARES Nets.
RACES focuses on civil defense, activated by government officials under FCC §97.407 FCC §97.407. It’s integrated with emergency management; in Brunswick County, NC, RACES drills occur on 145.270 MHz (PL 100.0 Hz).
Other networks include the Hurricane Watch Net (HWN) on 14.325 MHz USB, activating for tropical storms and providing real-time reports to WX4NHC at the National Hurricane Center Hurricane Watch Net. The Maritime Mobile Service Net on 14.300 MHz USB supports offshore operators, with daily sessions at 1200 UTC Maritime Mobile Service Net.
To join: Contact your ARRL Section Manager (for NC, Karl Bowman, W4CHX, at nc.arrl.org) NC ARRL Section, attend meetings via clubs like the Brunswick Shores Amateur Radio Club (n4gm.org), which hosts nets on 147.135 MHz (PL 100.0 Hz) Brunswick Shores Club. Membership often requires an FCC license and background check for ARES/RACES.
Forming Your Own Ham Net: Steps and Considerations
If no local net fits, start one. Begin with a purpose—e.g., weekly training or emergency preparedness. FCC §97.1 promotes such organization for advancing skills FCC §97.1.
Steps:
Define Scope: Local (VHF simplex like 146.520 MHz) or regional (HF like 7.268 MHz LSB for NVIS). For NC coastal hams, focus on hurricane prep.
Select Frequency: Use ARRL band plans to avoid conflicts. For VHF, check repeater directories like repeaterbook.com RepeaterBook; request coordination from the North Carolina Repeater Council (ncrepeatercouncil.org) NC Repeater Council. Simplex: 146.520 MHz nationally, or 145.555 MHz locally if clear.
Appoint NCS: Rotate roles; train via ARRL’s Emergency Communications Course (arrl.org/online-courses) ARRL EmComm Course.
Schedule: Weekly, e.g., Thursdays at 1900 local, announced on club sites or ARRL forums.
Promote: List on netfinder.radio NetFinder, or ARRL Net Directory (arrl.org/nets) ARRL Net Directory.
During the 2022 Idaho wildfires, ad-hoc nets formed on 146.420 MHz simplex coordinated amateur efforts with fire agencies, per ARRL ARES updates from September 2022 ARRL on Idaho Wildfires.
Frequency Coordination: Navigating FCC and Band Plans
Coordination avoids QRM (interference). FCC §97.101 requires courteous operation; no exclusive rights except during emergencies (§97.401) FCC §97.401.
For repeaters: Submit to coordinators like SERA (sera.org) for Southeast, including NC SERA. Process: Propose frequency (e.g., 147.000 MHz output, 147.600 MHz input, PL 88.5 Hz), await approval (months).
Simplex: Stick to calling frequencies—146.520 MHz VHF, 446.000 MHz UHF ARRL Simplex. HF: Nets like SATERN (Salvation Army Team Emergency Radio Network) on 14.265 MHz USB for relief SATERN.
Monitor with scanners or SDRs before claiming. In NC, the Statewide ARES Net uses 3.923 MHz LSB Sundays at 2000 UTC NC Statewide Net.
Net Etiquette: Keeping Things Smooth and Professional
Etiquette ensures efficiency. ARRL’s Operating Manual stresses: Identify fully (§97.119), listen before transmitting, follow NCS directives ARRL Operating Manual.
Tips:
Use phonetics: “Kilo Four Romeo India Charlie Kilo” for K4RICK.
Short transmissions: State callsign, message, end with “over.”
No jargon overload for newbies; explain terms like “QSL” (acknowledgment).
Handle traffic: Priority for emergencies; use formal message formats (ARRL Radiogram) ARRL Radiogram.
In directed nets, wait for NCS cue. Breakers: “Break” for urgent, “Info” for non-priority.
Scheduling Drills: Building Readiness
Drills simulate crises. ARRL’s Simulated Emergency Test (SET) occurs annually, like October 2025, testing plans ARRL SET.
Schedule: Monthly for basics (gear checks), quarterly for scenarios (e.g., power outage sim on battery). Use scripts to standardize.
Example from Klamath County ARES: Weekly nets on 146.980 MHz (PL 123.0 Hz) include roll calls and message passing Klamath ARES Script.
Track participation; debrief post-drill.
Scaling Nets: From Local to National
Start local: Club nets on VHF repeaters, like Cape Fear ARS on 146.820 MHz (PL 100.0 Hz) Cape Fear ARS.
Expand regionally: Link via HF for NVIS (3.900-4.000 MHz) or Echolink for IP bridging.
National: Join networks like the National Traffic System (NTS), with daily cycles on HF for message relay ARRL NTS. Or SHARES (Shared Resources HF Radio Program) for federal interop on allocated freqs like 5.357 MHz USB, requiring registration SHARES.
In the 2024 Southeast floods, ARES nets scaled by relaying via HF to national hubs, per ARRL updates ARRL on Southeast Recovery.
Sample Net Script: Adapted from SC Midlands ARES
Here’s a real script from South Carolina Midlands ARES Training Net (July 2024 version), used on 147.330 MHz (PL tone unspecified) Thursdays at 1900 local SC Midlands Script. Adapt for your group.
Preamble (10 min prior): “This is [Callsign], net control for the [Net Name]. This frequency will be in use starting at [Time]. Please keep it clear. [Callsign] clear.”
Net Start: “QST, QST, QST. This is [Callsign phonetically], net control for the [Net Name]. My name is [Name], located in [City]. This net meets [Schedule] on [Frequency] with [Tone]. The purpose is [Purpose, e.g., training and check-ins]. This is a directed net; all stations check in through net control.”
Roll Call: “Now calling for check-ins. Stations with emergency or priority traffic, come now. [Pause]. Hearing none, now check-ins by call sign suffix: Alpha through India... [List].”
Business: “Any announcements? [Handle]. Now opening for comments or questions. [Manage].”
Close: “This concludes the net. Thanks to all. The frequency is returned to normal use. [Callsign] clear.”
This format keeps things orderly; practice as NCS.
Success Stories from Ham Networks
Real activations inspire. During the 2022 Wisconsin floods, ARES nets on 145.430 MHz coordinated rescues, with operator John Tappero, K7JNT, relaying a 911 call that saved a hiker, as reported by ARRL in September 2022 ARRL on Wisconsin Saves.
In the Philippines after Typhoon Hagupit in 2014, hams activated nets on 7.095 MHz LSB, supporting Red Cross logistics, per ARRL ARES Letter December 2014 ARRL on Hagupit.
These examples show nets’ impact; local groups like DC ARES run weekly training on 145.430 MHz (PL 114.8 Hz) to prepare DC ARES Script.

Super thorough breakdown. The Hurricane Maria example is a perfect illustration of why these networks matter before disaster hits, not after. I've been involved in a few local ARES check-ins and the discipline aspect of directed nets is undertated, it really prevents the chaos that happens on open freqs during emergencies. The script template at the end is genuinely useful for anyone trying to start a new net.
