Daniel, if your scanner has a round dome, take the dome off and inspect
it. We're on our 3rd...or is it 4th, I forget....

The water vapor the stupid dome breathes in when the sun goes down makes
it rain inside the dome by morning, a cycle that keeps repeating, filling
the dome with condensate that doesn't drain. The inside parts of the 2KW
dome are made of some cheap zinc potmetal that turns to powder and has
electrolysis with the other, more noble metals like the rusty magnetron
and waveguide parts. The white powder is all over the INSIDE of the
receiver/transmitter compartments in the unsealed zinc box, so its all
over the boards and the unit eventually dies, consuming itself.

I've looked at several other Raymarine radomes on other boats all
wondering why range keeps getting shorter. Same thing on all boats.
Poorly designed, cheap parts that don't belong at sea.

You probably are way overdue for a new crappy Raymarine scanner,
anyway...sorry.

@twister1.libero.it:

Five years ago I bought a radar Raymarine SL72 (Pathfinder Plus). Last
year, as I wanted to have an integrated system, I bought a C120 display
sure that the SL72 scanner would fit the display. Wrong! After several
attempts and inquiries I discovered that my scanner was built 6 (six)
months before Raymarine started making units compatible with the C
series displays (June 2002 vs Dec 2002).
Do you think that this is fair? Does anybody know whether Raymarine
helps to solve unfortunate cases like mine?
I'd like to add something mo before buying the C120 I checked some
Raymarine docs and found that the new display would have been
compatible
with all scanner with a P.N. newer than a certain number. My scanner
had indeed a P.N. GREATER than that and this is why I decided the buy,
but... BUT I later realized that Raymarine is one of the few company in
the world (as far as I know) that DOES NOT use an incremental P.N. but
a
quite odd system. Greater P.N. does not mean newer!

Advice is kindly requested and welcome

Daniel
