Clear all spots and signal-history markers from the panadapter

Remove every DX spot, memory marker, Signal History voice marker, and QRM interference marker from the spectrum display in one action.

Before you start

• Open the SpotHub dialog: Settings > SpotHub...

Steps

1. Click the Display tab.
2. Click Clear All.

All spots from every source (DX cluster, RBN, WSJT-X, SpotCollector, POTA, FreeDV), memory-channel overlays, and Signal History markers (both gold voice markers and red QRM markers) disappear from the panadapter.

Tips

• Clear All is a non-destructive action — it only removes current marker overlays from the spectrum. Connected spot sources (cluster, RBN, etc.) continue running and will repopulate the panadapter as new spots arrive.
• To stop spots reappearing, toggle the master Spots: toggle button to "Disabled" on the Display tab, or disconnect each source on its respective tab.
