Identify which slice is the TX slice

The DAX Applet shows a live TX assignment indicator that tells you which slice currently holds TX privileges. Use this when you need to confirm the transmit slice before operating digital modes or checking DAX TX audio routing.

Before you start

• AetherSDR must be connected to the radio. The TX assignment indicator requires an active radio connection.
• The DAX Applet must be visible. It is hidden by default.

Steps

1. Click the DAX tray button on the right sidebar to open the DAX Applet.
2. Look at the TX: row at the bottom of the applet.
3. Read the status indicator to the right of the TX: label. It shows either — (no TX slice assigned) or Slice A through Slice H (the slice currently holding TX privileges).

What each control does

Control	Description	Default	Valid states	Setting key
TX assignment indicator	Shows which slice currently has TX privileges. Updates automatically when TX is moved between slices.	—	— or Slice A–Slice H	none

Tips

• The TX indicator updates in real time. If you transfer TX to another slice on the radio, the indicator changes immediately without any manual refresh.
• The RX rows above the TX row show per-channel DAX assignments (DAX 1: through DAX 4:). These indicate which slice is routed to each DAX RX channel and are separate from the TX assignment.
