I have a 1998 Furuno
model 1832 green-screen radar
with a 24" radome that has been flawless until my most recent trip when it would intermittently fail to display any targets. With 2200 hours, I initially thought it was time to replace the magnetron. Rather than a gradual loss of sensitivity, however, it appears instead to be either on or off. One variable may be the cold weather
we were sailing in when it malfunctioned, with it restoring itself once the weather
warmed up a bit.
Anybody know if this sounds symptomatic of a failing magnetron or possibly in the wiring
? I read that Furuno
is no longer supporting this model, and don't know if purchasing
a new magnetron or antenna
wire is even an option. It has otherwise been an excellent unit so I am hesitant to bail on it.
Thanks for any info.
