+# Contest Logging
+
+**Contest tab.** Pick a contest and an exchange, and OpsLog handles the rest.
+
+## Setup
+
+- **Contest** — from the built-in ADIF `CONTEST_ID` list.
+- **Exchange** — a **running serial** (auto-incrementing) or a **fixed exchange**.
+- **Window** — start / end times; QSOs outside are flagged.
+
+## While operating
+
+- OpsLog auto-fills `CONTEST_ID` and the **sent / received serials** (`STX` /
+  `SRX`).
+- **Dupe** detection flags a call already worked in the contest.
+- A live **scoreboard** tracks your progress.
+
+## Export
+
+Export the contest log to **Cabrillo** for submission (Recent QSOs → export), or
+to ADIF. See [[Import and Export ADIF]].
+
+## Tip
+
+Use **Bulk edit field** (right-click in Recent QSOs) to fix a contest field
+across many QSOs at once — e.g. set `CONTEST_ID` or an exchange string on an
+imported batch.
