[CA] [CA11] Pathfinder Gain Setting

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Evan,

Q1. if the auto tune setting is what is to be expected in this case
A1. Auto tune should not be used by any person other than a radar technician,

Q2. Is it normal to not see echoes in this type of environment until the gain is cranked up above 80%.
A2. If the sea clutter setting has been configured too high, then the performance which you have describe will occur. Should the problem persist after reducing the sea clutter setting, then it would indicate a problem within the radar transducer's circuitry. As you have suggested, Raymarine can no longer service radar transducers which were designed for use with hsb/hsb2/SL Pathfinder Series Radar Displays, nor are replacements available.
