# Net Control

**Directed-net logging** (Tools → Net) — run a directed net or round-table and
log the whole thing at once, Log4OM-style.

## How it works

- **Roster** (right) — the net's registered stations, stored globally in
  `nets.json` (shared across profiles). Add contacts with a QRZ/HamQTH prefill.
- **On-air** (left) — the active session (in memory): put a station on the air
  (check it in), and log the whole net when done.
- Frequency / band / mode of each logged QSO come from **live CAT** at log time
  (falling back to the last known values if CAT is off).

## Working a net

1. Open / create a net and **Open** it.
2. Double-click a roster station (or use *Put on air*) to put it on the air —
   this starts its QSO (time on).
3. Double-click an on-air row to open the full QSO editor (edit any field).
4. **Log & end** a station to write its QSO to the logbook (time off = now).

## Worked-before

Click a station (on air or in the roster) to see prior contacts with it in the
**worked-before** panel below the on-air column. The panel height is adjustable
(drag its top edge).

> The active session is in-memory only — closing the app mid-net drops
> un-logged on-air stations.
