Which of the following are typical duties of a Net Control Station?

A Net Control Station (NCS) acts like a traffic cop for an amateur radio net. Their primary duty is to maintain order by calling the net to begin, acknowledging check-ins, and directing the flow of communication between participating stations. This ensures messages are passed efficiently and stations do not talk over one another. While an NCS manages the active session, they do not dictate the regular meeting times (which are usually set by club management or net coordinators), nor do they police the license status of every checking station. Each individual operator is always responsible for ensuring they are operating within the privileges of their own license.
