A radio net is three or more radio stations communicating with each other on a common channel or frequency. A net is essentially a moderated conference call conducted over two way radio, typically in half duplex operating conditions. The use of half duplex operation requires a very particular set of operating procedures to be followed in order to avoid inefficiencies and chaos. Nets operate either on schedule or continuously (continuous watch). Nets operating on schedule handle traffic only at definite, prearranged times and in accordance with a prearranged schedule of intercommunication. Nets operating continuously are prepared to handle traffic at any time; they maintain operators on duty at all stations in the net at all times. When practicable, messages relating to schedules will be transmitted by a means of signal communication other than radio. Net operations:
allow participants to conduct ordered conferences among participants who usually have common information needs or related functions to perform
are characterized by adherence to standard formats and procedures, and
are responsive to a common supervisory station, called the "net control station", which permits access to the net and maintains net operational discipline.

A net manager is the person who supervises the creation and operation of a net over multiple sessions. This person will specify the format, date, time, participants, and the net control script. The net manager will also choose the Net Control Station for each net, and may occasionally take on that function, especially in smaller organizations.

Maritime mobile nets serve the needs of seagoing vessels.

When boats or ships are in distress, they will operate a maritime broadcast communications net to communicate among the vessel in distress and all the other vessels, aircraft, and shore stations assisting in the distress response.
