This is turning out to be a big year of gear
failures for me
My boat is 11 years old and has been in use for about 9 of those; I guess it must just be that a lot of items of gear
are reaching their sell-by dates.
The latest problem -- just when I'm in the middle of solving others -- is that my Raymarined network is losing GPS
data intermittently. I have a Raystar 125 mounted to the pushpit. This feeds GPS
data to an older Raymarine
network consisting of RL80CRC+ at the nav table, RL70RC+ at the helm
, and the other usual gear.
I recently connected the NMEA
output from the RL80CRC+ to my Icom
in order to have position and time data for the DSC
functions. This has been working fine for the last couple of months so I doubt any connection to the problem.
Now occasionally the system will lose GPS data and sound and alarm
: "Lost Fix". This tends to occur on startup of the system and tends to go away after half an hour or so.
Does this sound like a bad connection? Or do the Raystar GPS receivers
fail in this manner? Should I replace it? Then what with -- if I want the new receiver to be compatible with a new network (which will presumably be NMEA2000)?
I guess the main thing I need to know is whether or not there is a failure mode of these GPS receivers
which is not a simple dead failure like most electronc gear, or whether this kind of behavior can be a bad GPS receiver. If they never fail like that, then I guess I need to be looking for a bad connection or worse -- some kind of other failure in the network.
As always I will be very grateful for pearls of wisdom from those more knowledgeable and/or more experienced than I.
