DX Cluster Startup Commands overview

Define custom commands that AetherSDR sends to a DX cluster or Reverse Beacon Network (RBN) immediately after each login and automatic reconnect. This lets you apply your preferred filter, announcements, or operational settings (e.g., set/dx or set/wwv) without manually typing them each time.

How it works

When AetherSDR connects (or reconnects) to a DX cluster or RBN node, it sends every line in the corresponding command list, one per line, immediately after the login handshake completes. The same commands are replayed after every automatic reconnection triggered by a network drop.

Two independent command sets are stored and managed:

• DX Cluster — commands sent to the cluster configured on the DX Cluster tab in SpotHub (DxClusterStartupCommands AppSettings key).
• RBN — commands sent to the Reverse Beacon Network tab in SpotHub (RbnStartupCommands AppSettings key).

What each control does

Control	Default	Valid range / Notes	AppSettings key
Command editor (multi-line plain text editor)	(empty)	One command per line. Blank lines are ignored. No limit on number of lines.	DxClusterStartupCommands (main tab) / RbnStartupCommands (RBN tab)

Opening the dialog

Open Settings > SpotHub..., then click Edit Startup Commands on either:

• The DX Cluster tab — to edit the main cluster command set.
• The RBN tab — to edit the RBN command set.

Tips

• Commands are sent in the order they appear in the editor, top to bottom.
• Typical startup commands include set/dx (enable DX spots), set/announce (enable announcements), or set/filter to limit spot types. Check your cluster's help (help) for available commands.
• If a command requires a response from the cluster (e.g., a status confirmation), AetherSDR does not wait — it sends all lines immediately. For time-sensitive sequences, keep them short.
• Changes take effect on the next connection or reconnect; they are not sent to an already-connected session.
• The dialog now uses the active theme's color palette. Backgrounds, text colors, and accent colors adapt automatically to the current UI theme selection.
