I have a
Raytheon RC530
Chartplotter with Raystar 120
GPS receiver.
I've been getting the dreaded intermittent "No Fix" error for some time, so I replaced the on board
lithium battery in the Raystar 120. Still have the same problem so it appears to be more than the
battery that is causing a problem.
I'm looking for a cheaper replacement than the Raystar 130 with
Seatalk to
Seatalk NG converter at about $400.
I've looked at the Evermore SA-320 and SA-920 but they are not
sold in the U.S.
Are there any other name brands
sold here that have been proven to
work?
Specs would be NEMA 0183 Ver. 2.3 output, RS422, 4800 baud 8, none , 1
Many of the units sold now are NEMA 2000 or they don't list the specs in the owners
manuals that I found online.
Any help would be greatly appreciate, by me and many other Raystar 120 owners with failing receivers.
