A net is a regularly scheduled on-air meeting with other amateur radio operators. These “Nets” (as in “networks”) are moderated by a station referred to as “Net Control”. Nets can allow operators to learn procedures for emergencies, be an informal round table or be topical, covering specific interests shared by a group.

Some local nets are operated on a simplex frequency to ensure that the local operators can communicate between themselves without relying on a remote repeater that might not be available in the aftermath of a disaster. This would also allow communications in a local area without being subjected to interference from communications from outside the local area. Other local nets use a local repeater due to topographic or other obstacles to simplex operations.
