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¶
- 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.
- 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.
- 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.
