T&T: Radar Performance Question

[John Baker]

Wayne,
 
    I would imagine what you would adjust would be the gain(or volume).  If
the radar cannot see thru the rain(attenuation) to begin with, no adjustment
will help.  As you adjust the gain(turn the volume down), you are basically
turning it down to the point that it no longer sees the rain(or anything
else).  If the rain was inpenetrable to begin with, you are just turning down
the gain to where it will not see "anything".....if that makes sense.  To put
it simply, if it cannot see thru the rain with the gain in the normal/default
position, then it still won't be able to see thru it with the gain all the way
down.
 
Trawler on,
John

'Lo All,

I chose a 4KW 48 mile radar simply because I can see thunderstorms
further away and, hopefully, be able to avoid them. Fun to watch
F-15s and other aircraft when at low altitudes, too! Shades of
another lifetime....

Anyway, other than for weather, I believe that a 4 KW 48 mile radar
is overkill. But....weather is a very serious factor on the Gulf of
Mexico and adjoining bays, which is why we have it. Ours is a
Raymarine. Once, in a torrential rain squall on St. Andrews Bay (I
could barely see the bow of the Celestial for short periods of time),
after adjusting for rain and all, the CRT was almost as clear as it
is in clear weather. I was astounded at how well it worked.

YMMV


Take care and be safe.
