Amateur radio nets are scheduled on-air gatherings where licensed operators check in with a designated net control station. They range from informal ragchew gatherings on a local repeater every Tuesday evening to highly structured national emergency communication nets handling formal message traffic. Regardless of format, participating in nets regularly does more to develop operating skills than almost any other single activity. The structure is low-pressure, the community is welcoming, and the practice adds up fast.
Types of Amateur Radio Nets
Traffic Nets
Traffic nets exist to pass formal messages — NTS (National Traffic System) radiograms — between operators and eventually to final delivery. Messages follow a standardized format with preamble, address, text, and signature. Traffic handling teaches precise communication discipline that carries over to every other aspect of operating. The ARRL's National Traffic System connects local nets to regional and national nets, forming a relay chain that can deliver a message from California to Maine via radio. Traffic nets run on both HF and VHF, and most welcome observers who want to learn the procedure before participating.
Emergency Communication Nets
ARES, RACES, and SKYWARN nets run on a scheduled basis specifically to maintain operator readiness for real activations. Weekly or monthly nets confirm that equipment works, operators know the procedure, and Winlink connections are functioning. Most ARES sections require regular check-ins to maintain active member status. These nets are also where you learn how an actual activation would be run — net control procedure, priority traffic, ICS form exchange — without the pressure of a real emergency.
Ragchew Nets
Informal conversational nets where operators check in, exchange signal reports and sometimes traffic, and may engage in brief conversation. These are the most welcoming entry point for new operators. No special knowledge required — just call in when net control takes check-ins, give your callsign and any traffic, and participate in whatever discussion follows. Many local clubs run weekly ragchew nets on their club repeater that have been running continuously for decades.
DX Nets
Organized networks of operators specifically working to facilitate contacts with rare or distant stations. The Maritime Mobile Service Net on 14.300 MHz is a famous example — connecting maritime mobile operators with shore stations worldwide. DX nets often have formal procedures for routing contacts and maintaining schedules across time zones and propagation windows.
Technical and Special Interest Nets
Nets organized around specific interests — satellite operations, digital modes, CW (Morse code) practice nets for operators learning or maintaining their code speed, QRP nets for low-power operators, antenna building discussion nets, and more. The ARRL Net Directory lists over 2,500 active nets organized by type, frequency, and schedule.

The Check-In Procedure: Step by Step
Net procedure varies by net type but the fundamentals are consistent. Most nets open with net control calling for check-ins, and you respond during that window.
On a VHF FM repeater net: When net control says "This net is now open for check-ins," key up and give only your callsign: "Whiskey One Alpha Bravo Charlie." Net control will acknowledge you, possibly ask if you have traffic (a message to pass), and log you in. That's it. Keep it brief — there may be dozens of others waiting to check in.
On an HF SSB net: Similar procedure, but you may need to be more deliberate about frequency discipline. Listen for a clear opening in the net control's cadence. Give your callsign phonetically. If you have traffic, say "with traffic" after your callsign. Net control will call on you specifically to handle it.
On a CW net: Give your callsign in CW at the speed the net is running. Most CW nets run between 15–25 WPM. If you're below that speed, listen-only participation is perfectly appropriate until your code speed develops.
Common mistake: Checking in with more information than net control asked for. When net control says "check-ins only," they mean callsign only — not your name, location, signal report, and weather. Save the conversation for after the net or when invited. Brevity keeps the net moving and is considered good operating practice.
Net Control: How the Other Side Works
Net control is responsible for opening the net, calling for check-ins, acknowledging each station, facilitating traffic exchange, handling priority check-ins, and formally closing the net. Running net control for the first time is intimidating but becomes comfortable quickly. Most clubs maintain a roster of trained net control operators and welcome new volunteers after they've observed several nets as a participant.
A basic net control script for a simple VHF repeater net:
- Open the net with time, frequency, net name, and your callsign
- Call for emergency or priority traffic first (always)
- Call for check-ins by alphabetical suffix, area, or simply "any stations"
- Acknowledge each check-in, note traffic if any
- Handle traffic exchange between appropriate stations
- Close the net with total check-in count and time
NTS Traffic Handling: The Formal System
If you're participating in a traffic net, messages follow a specific format called the NTS radiogram. The format has five components: preamble (message number, precedence, originating station, check, place of origin, time filed, date), address, text, signature, and any end-of-message indicators.
Precedences are ROUTINE, WELFARE, PRIORITY, and EMERGENCY. Emergency traffic goes first, always. Welfare traffic — messages inquiring about the safety of persons in a disaster area — goes next. Most traffic nets handle only routine and welfare traffic in normal operations.
The ARRL's radiogram form is available as a free download and as a printable PDF. Many operators keep a stack in their shack. Completing and passing your first formal NTS radiogram is a satisfying milestone that few new operators achieve but those who do carry the skill for life.
Building Nets Into Your Operating Routine
The operators who improve fastest are those who show up consistently — same net, same frequency, same time each week. A 30-minute check-in to your local club net every Tuesday adds up to 26 hours of structured operating practice per year. That's more than most casual operators spend on air in total. The social dimension also matters: regular net participants know each other, help new operators, and form the social backbone of the local amateur radio community.
Find one local VHF net and one HF net that match your schedule. Check in consistently for 90 days. You'll emerge with a level of operating confidence and community connection that solo contact-hunting rarely produces.
Starting point: The ARRL's W1AW operates several on-air nets including code practice transmissions, bulletins, and operating events. Listening to W1AW's scheduled transmissions is excellent practice even before you're ready to participate in interactive nets. Schedule at arrl.org/w1aw-operating-schedule.
