A net (short for network) is an organized, on-air meeting of amateur radio operators, conducted on a specific frequency at a scheduled time. Nets serve many purposes — from casual social gatherings to formal emergency communication drills — and they are an excellent way for new operators to get comfortable on the air in a structured, supportive environment.
Most nets follow a similar structure:
The NCS is responsible for maintaining order, keeping the net on schedule, and ensuring all participants have a chance to be heard.
Many amateur radio clubs hold weekly nets on a local repeater or HF frequency. These are typically informal round-table discussions where members check in, share news, discuss the hobby, and socialize. Social nets are one of the best ways for new operators to practise their on-air skills because the NCS provides structure and prompts.
Traffic nets exist to relay formal written messages (called "traffic" or "radiograms") across the amateur radio network. The National Traffic System (NTS) in the United States, and similar systems in other countries, organizes nets at local, regional, and national levels to move messages from origin to destination.
Messages follow a standard format with a preamble, address, body, and signature. Traffic handling is a skill that ties directly to emergency communications — the same procedures used to pass routine messages in peacetime are used to handle critical messages during disasters.
Emergency communication organizations like ARES (Amateur Radio Emergency Service) in the US, RAYNET in the UK, and similar groups worldwide hold regular practice nets. These nets train operators in the specific procedures used during real emergencies, including formal message handling, resource tracking, and coordination with served agencies.
During an actual emergency, these nets transition from practice to operational use, often running continuously for the duration of the event.
Some nets focus on specific technical topics, modes, or interests. Examples include:
A directed net is tightly controlled by the NCS — all communication goes through the NCS, and stations do not talk directly to each other without permission. Directed nets are used for emergency operations and formal traffic handling, where clear, orderly communication is essential.
An open net allows stations to communicate freely once checked in, with the NCS providing light guidance. Most social nets operate as open nets or a hybrid, where the NCS facilitates discussion but does not strictly control every transmission.
The check-in process varies by net, but the general approach is:
Tips for checking in:
If you are asked or want to serve as Net Control, here are the key responsibilities:
Preparation — Know the net's purpose, script (if any), and format. Have a logging sheet or software ready to record check-ins. Know the frequency and any backup frequencies.
Opening the net — Announce the net name, frequency, purpose, and your callsign. State whether the net is directed or open.
Managing check-ins — Acknowledge each station that checks in. If conditions are poor, ask stations to spell their callsign phonetically. Keep a list of all checked-in stations.
Facilitating the round — In a round-table net, call on each station in order. Give each station a clear invitation to speak ("Next we'll hear from [callsign]") and manage transitions.
Handling traffic — If your net handles traffic, prioritize stations with traffic to pass. Pair them with the appropriate receiving stations.
Timekeeping — Keep the net moving at a reasonable pace. If one station is monopolizing the conversation, politely move to the next station.
Closing the net — Ask for any late check-ins, thank participants, announce the next net time, and formally close the net with the net name and your callsign.
Nets are listed in several places:
Some nets use NetLogger or similar software that allows participants to see who is checked in, track their position in the round, and follow the net in real time on a computer screen. The NCS posts the net session online, and participants connect to it while listening on the radio.
