DX Cluster

Live DX spots streamed via telnet from DX cluster nodes. POTACAT supports up to 3 simultaneous cluster connections.

Setup:

1. Enable DX Cluster in Settings → Spot Sources
2. Enter your callsign (required for cluster login)
3. Choose from 13 preset nodes (W3LPL, VE7CC, DXUSA, NC7J, K1TTT, and more) or add a custom node
4. Optionally add a second and third node for broader coverage

DX Cluster spots appear with a purple left border in the table and purple markers on the map. Location is resolved from the callsign using the bundled cty.dat country database.

DX Command Bar: When DX Cluster is enabled, a command bar appears below the table. Use it to self-spot or spot other stations on the cluster. Enter a callsign, frequency, and optional comment, then click Send.

Spotting on the cluster: The Log dialog includes a “Spot on DX Cluster” checkbox for non-park contacts. Press Ctrl+R for quick re-spotting with template variables.
