A simple net consists of which components?

• A. Control stations and 2 or more substations
• B. A single station
• C. Two control stations only
• D. Substations only

Answer: (A)

In a radio net, a net control station acts as the traffic manager, calling stations, authorizing turns to transmit, and relaying messages to keep communications orderly. A simple net needs at least one control station to coordinate traffic and two or more participating stations (substations) to actually relay and exchange messages. With only a single station, there’s nothing to coordinate or relay, so it’s not a net. With only control stations, there are no participants to talk to. With substations but no control, there’s no one to manage the flow of traffic. Therefore, the minimal and correct setup is a control station plus two or more substations.
