# DX Cluster and Spots
## Servers
Add multiple cluster servers (Settings). They auto-reconnect; one is the
**master** used for sending commands. A quiet node is not treated as a dead one
— silence keeps its session, login and filters. 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**, plus **NEW POTA** and
**NEW COUNTY** chips.
## Per-spot status and tuning
Each spot is coloured by **status** relative to your log:
- **new** (entity never worked), **new-band**, **new-mode**, **new-slot**,
**worked**.
- Settings → General → **Group digital modes as one (DXCC-style)** makes
FT8/FT4/RTTY/PSK count as a single Digital mode for the colouring and the
matrix badges, matching how DXCC counts.
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 — its CW / data
/ phone sub-bands use their own colour-blind-checked hues, and **Ctrl+↑ /
Ctrl+↓** jumps to the next spot above/below the current frequency and tunes it.
**POTA** spots are tagged with their park reference (via `api.pota.app`).
The entry strip's band matrix can also show the **ClubLog Most Wanted rank**
(Settings → General): an `MW #rank` pill next to the entity name, personalised
to your callsign, refreshed daily.
## 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.
## External spot sources
A **DXHunter** remote-call UDP packet fills the callsign, and when it carries
`<FREQ>` and `<MODE>` it also tunes whichever CAT backend is active. See
[[Settings and Data]] for the UDP configuration.
See also: [[Maps and Antennas]] for turning the beam to a spot.
