Multi-Slice Operation

AetherSDR supports multiple simultaneous VFOs (slices) on the same panadapter.

Adding a Slice

• Click +RX in the left sidebar menu
• A new slice appears with its own colored VFO marker

Slice Colors

Slice	Color
A	Cyan
B	Magenta
C	Green
D	Yellow

Switching Active Slice

• Click the slice badge on the spectrum to switch focus
• Click the VFO marker line to switch
• The VFO widget updates to show the active slice's controls

TX Assignment

• TX stays on its assigned slice until explicitly moved
• Red TX badge — active TX slice
• Grey TX badge (in VFO widget) — click to move TX to this slice
• Switching active slice does NOT move TX

Closing a Slice

• Click the ✕ button floating beside the VFO widget
• Or right-click on the spectrum → Close Slice
• You cannot close the last remaining slice

Off-Screen Slices

When a slice is panned off-screen, an arrow indicator appears on the FFT edge showing:

• Slice letter and direction
• VFO frequency

• FLEX-6400/6400M: 2 slices
