I have a raytheon pathfinder RL70, a scanner and a gps antenna. I picked these up at a marine
swap meet for next to nothing and my expectations were mainly just to have the stuff in front of me that I could use to learn a little bit about marine radar
. I was able to connect the raytheon scanner unit to the RL70 and did get a nice radar signal on the LCD. However, I would really like to see if I could also get the GPS function to work.
I understand some GPS units have internal batteries that eventually weaken and fail so I opened the GPS antenna unit up and with a little creativity, I was able to replace the 3v button battery
. I did this mainly to give this GPS unit a fighting chance.
The GPS antenna has five wires:
The seatalk cable that I have has three wires:
I tried the obvious and connected the three matching wires; plugged it all in to no avail.
Again, since I'm not currently in a foggy ship channel, there is no real concern but It would be nice to see If I could get the GPS to function.
Any suggestions about how to investigate GPS functionality?
