Use this page to make spot callsign text larger or smaller on the panadapter. Adjusting the font size helps when spots are hard to read at a distance or when they overlap other display elements.
AetherSDR must be running. A radio connection is not required to change this setting.
The Spot Settings dialog must be accessible from the panadapter. If spots are not visible, confirm that the IsSpotsEnabled toggle is set to Enabled — see Turn spots on or off.

Spot Lines:

A font size of 16 is the default. Values toward 8 reduce clutter when many spots are visible; values toward 32 help when viewing the panadapter from a distance.
Font size applies to all spots simultaneously. There is no per-spot size override.
Disabling Spot Lines: can significantly reduce visual clutter during contests when a large number of spots are active.
The Spot Settings dialog now respects the current theme. If you have a custom theme applied, the dialog title and Total Spots label will use your theme's text colors.
Toggle buttons (Spots, Memories, Override Colors, Spot Lines) always display "Enabled" regardless of their current state. Check the button's visual highlight to determine the actual state — a highlighted button indicates the feature is enabled.
