My Raystar 120 Seatalk GPS antenna is definately duff.
New Raystar 125 is £250 ferchrissake.
Ebay has a pattern GPS ant that gives its output in NMEA and states that some Raymarine stuff can work on either NMEA or Seatalk .Info is somewhere in operating system.
Anyone know how to find out if my blimming RL70CRCPlus will work on NMEA. ?

I believe that the common cause of failure of the 120 is that the battery inside the unit has expired. If you're moderately handy with a soldering iron you could probably replace it - although because the 120 is hardwired you'd have to cut the cable in order to get the unit off the boat (or completely remove the cable back to where it joins your seatalk network, hard work). I can probably find a photo of the innards of a 120 if it'll help you?

I'm pretty sure the 70crc will work on nmea0183. It has nmea0183 input, and you just use the menus to tell it to get its gps position from the nmea input rather than the seatalk1 input

The 70crc manual is probably online somewhere, maybe on Ray's website under legacy products. Though you may not need it - you can just look in the (fairly intuitive) menus to see if you can select nmea as the GPS source

Thanks to all who replied.Have just applied the Dremel grinder to attack :) plastic dome containing the GPS pcb.It contains a Varta CR2032 3v button cell with soldered tags.
Will replace battery tomorrow and see what happens !
 
thanks for info on replacement - just wonfdering if it will still work as my system is set up with seatalk - access to wiring is a nightmare.

dont want spend £20 on new raystar to find it is not thr problem !!

My system is a RL70CL and was apparently set up with Seatalk.Wired new GPS ant. bare wire ends to the little super dooper special "Raymarine" connecter" ie. bit of cheapo chocolate block stuff", reset to default and off it went.
It mentions on Raymarine website that you supposed to set up for NMEA but mine just worked ?

The RL70s and RL80s all work with this antenna, also C70, C80, RC425, Lowrance, Northstar, Navman, you name it, it works except for the old LMS350A!
