SpotHub

The SpotHub dialog is the central control for connecting to DX spot sources, including a traditional DX cluster, the Reverse Beacon Network (RBN), WSJT-X, SpotCollector, POTA, and FreeDV.

Startup Commands Editor

The Cluster and RBN tabs each have a Startup Commands... button that opens a dialog for editing commands sent automatically after every login. Each source stores its commands independently.

Editing startup commands

  1. Click Startup Commands... on either the Cluster or RBN tab.
  2. Enter one command per line (e.g. SET/NAME, SET/QTH, ACCEPT/SPOT).
  3. Click OK to save, or Cancel to discard changes.

Commands take effect on the next connection or reconnection to the cluster.
