Start and close a session

Take a net live so stations can check in, and close it when the net is over. Starting and closing are owner actions, enforced server-side.

Prerequisites

Steps

Step 1: Start the session

Open the net and choose Start Net. There is nothing to fill in.

The session takes a snapshot of the definition as it stands right now — its ways in included, copied by value — and renders from that snapshot for its whole life. Editing the net's connection list afterwards does not move a session that is already running, which is what lets you fix a typo in the net without repainting a net that is on the air.

Starting no longer asks for an operating frequency. A net can be reachable several ways at once, or in no radio way at all, so there is no single frequency for a session to hold — each way in carries its own.

The session is now live. It appears in the active-now hero and is publicly readable.

Step 2: Retune a way in mid-net

If you QSY, use the frequency control on the session. Pick which way in moved — the picker appears only when the net has more than one way that can be retuned — enter the new frequency in MHz, and choose Set frequency. Ways with no frequency of their own, such as EchoLink or a DMR talkgroup, are not offered and cannot be retuned.

The change propagates to every connected viewer within about two seconds, and it moves that one way in and no other. It does not edit the net definition.

Only the net control station can retune. Anyone else gets HTTP 403 and no event is recorded.

Step 3: Close the session

Choose Close Net. NetRoll appends a close event, moves the session to closed, and stops accepting mutations.

The on-screen summary renders from the folded event log, so it reflects the session exactly as it ran.

Verify

After close, the session shows its summary, and the roster is frozen — attempting a check-in or an edit is refused. The session no longer appears in the active-now hero.

If you drop out

You don't have to close a session for it to end cleanly. If net control's heartbeat stops, the session pauses rather than ending, another qualified operator can claim control, and an abandoned session auto-closes after 15 minutes. See hand off net control and the session lifecycle.
