# 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.
