net operations



in depth

Net operations are a way of managing the communication flow on a frequency in amateur radio. These operations can be set up for a variety of purposes such as weekly club interactions, special event support, or communicating storm conditions. During a net operation, the primary station that is heard is known as the net control station. The net control station is responsible for calling the net to order and directing communications between stations that are checking in.

While participating in a net operation, it is considered standard practice to listen rather than speak unless directed to do so by the net control station. This is unless you need to report an emergency. Some nets are specifically set up for sending messages from one group to another, and these messages are referred to as "traffic."

In formal traffic messaging, the information necessary to track the message is stored in the preamble. Good traffic handling involves passing messages exactly as received to avoid confusion, especially in emergency situations. To ensure that a message is heard correctly, one can ask for a "check" which is the number of words or word equivalents in the text portion of the message. If the other operator confirms the correct number of words, you can be confident that the entire message was received correctly.


RACES and ARES are two different organizations that are related to emergency communications through amateur radio. RACES stands for Radio Amateur Civil Emergency Service and is an FCC Part 97 amateur radio service that is used for civil defense communications during national emergencies. ARES, on the other hand, is the Amateur Radio Emergency Service and is a group of licensed amateur radio operators who have voluntarily registered their equipment and qualifications for communications duty in public service.

According to FCC rules, amateur radio operators are allowed to transmit outside the frequency privileges authorized under their class of amateur license if the situation involves immediate safety of human life or protection of property. However, FCC rules always apply, even in emergency situations, and there are no special rules for emergency communication teams. One common exam question in amateur radio is when you can break FCC rules, and the answer is never, as the rules always apply.
