Which piece of information is the minimum to disseminate when closing a net?

• A. Time to re-open
• B. Relevant crypto information
• C. The frequency and mode to re-open it
• D. Net name

Answer: (A)

When ending a radio net, the goal is to keep information minimal while still letting participants reconnect smoothly. The crucial piece to share is the time when the net will reopen. Announcing a reopen time gives everyone a clear cue for when to listen again and join the next round, which keeps the session predictable and coordinated.

Other details aren’t needed to restart the net right away. Crypto information is sensitive and unnecessary for simply reopening; frequency and mode to reopen could reveal operational details that aren’t required for a basic restart and might pose security or interference concerns. The net name is just an identifier and doesn’t help someone actually rejoin the conversation. So the minimum, most effective information to disseminate is the time to reopen.
