[CA11] Radar gain control

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Matt,

Indeed the design of the filtering within the radar processing is to reduce the clutter within the closer range ... as you can see quite clearly in your photos. No changes to any of the radar sensitivity settings (gain, rain, sea clutter, color gain) or modes (Harbor, Coastal, Offshore, Weather, Bird) would be expected to cause speckling of the inner portion of the radar plot in the manner seen with the outer portion of the plot.
