Read signal history as a scrolling 3D surface

Enable the 3D FFT spectrum view to see signal history rendered as a forward-scrolling 3D surface instead of the traditional 2D waterfall. The surface shows elevation shadows from slice flags and resynchronizes its floor after bandwidth zoom.

Before you start

  • Your AetherSDR must be connected to a FLEX-8600 radio (see [Radio Setup...] in the Settings menu).
  • A panadapter must be visible in the main window showing spectrum and waterfall data.

Steps

  1. Locate the 3D FFT view toggle button on the panadapter — it is labeled with the 3D FFT icon and sits with the other spectrum controls in the SpectrumWidget area.
  2. Click the 3D FFT view toggle button once to enable the 3D surface view. The spectrum display switches from the flat 2D waterfall to a scrolling 3D surface.
  3. To return to the standard 2D view, click the same 3D FFT view toggle button again to disable it.

What each control does

Control Default Behavior Setting key
3D FFT view toggle Disabled Enables/disables the 3D FFT spectrum view showing signal history as a forward-scrolling surface with elevation shadows and smooth-scroll boundaries. None

Tips

  • Slice flags cast cached elevation shadows on the 3D surface, making active slice positions easier to identify at a glance.
  • The 3D surface floor resynchronizes automatically after you change the bandwidth zoom level, preventing a flat or misaligned baseline.
  • The 3D FFT view shares the same panadapter freeze behavior as the 2D waterfall — during transmit (from any client), the display freezes and resumes when transmission ends.
