Jim, I don't see this option in the manual and don't recall seeing it being set when I was reviewing the settings. Can you tell me how to get to it?
Thx,
Alex.
You have 2 clutter settings. STC and RTC.
STC = Sea Clutter. RTC = Rain clutter.
Basically, clutter reduction is a more accurate term. Unfortunately as you increase the clutter reduction you also reduce or eliminate the ability to see targets that are poor reflectors of radar.
This gets back to my suggestion of flipping the auto-settings off except for timing and manually adjusting the gain until you see some speckles or snow on the screen.
Assuming the area is clear in front of your radar array on top of your arch I think you will come back here and tell us you now are able to see all vessels, even very small boats like personal watercraft or flat boats with little freeboard like jon boats. Again, do this with clear, calm, daylight conditions.
I found that once got experience using radar and understood how to interpret what I was seeing on the screen in the best optimal conditions and was able to verify what I was seeing with my eyes I was able to progress to less and less optimal conditions.
This only goes so far. Big whitecaps and small targets like a PWC will eventually become impossible to distinguish at some point. If the PWC is between two waves as the radar sweeps that area the target does not show up. Also the waves themselves become targets. So you turn up the sea clutter settings until you no longer see the waves. At this point small poor reflecting targets disappear.
