+# DX Cluster and Spots
+
+## Servers
+
+Add multiple cluster servers (Settings). They auto-reconnect; one is the
+**master** used for sending commands. The Cluster tab and the Main-view cluster
+pane share the same live feed.
+
+## Filter sidebar
+
+A show/hide **filter sidebar** (shared by the Cluster tab and the Main pane):
+
+- **Callsign** search, **hide worked**, **group duplicates**.
+- Filter by **band / mode / status / source**.
+
+## Per-spot status and tuning
+
+Each spot is coloured by **status** relative to your log:
+
+- **new** (entity never worked), **new-band**, **new-slot**, **worked**.
+
+Click a spot to **tune the rig** (fills the callsign into the entry strip). A
+multi-band **Band Map** shows panadapter-style strips per band.
+
+**POTA** spots are tagged with their park reference (via `api.pota.app`).
+
+## Sending a spot
+
+Use the **Send Spot** window to announce a DX spot on the master cluster:
+callsign + frequency + a message. The frequency defaults to the **live CAT
+frequency** (full resolution, including sub-kHz).
+
+## Spot alerts
+
+**Tools → Alert management** — Log4OM-style alert rules on **call / country /
+band / mode / spotter**, with **sound**, **visual** and **e-mail** notification.
+Active alerts appear as a discreet bell in the entry strip; click it for the
+list. Alerts are kept briefly and only shown when active.
+
+See also: [[Maps and Antennas]] for turning the beam to a spot.
