Hello,
I'm installing the NX-300 as a stand alone unit without connection to other nav systems or to a PC.
My concerns arise from the paragraph on page 6-4 of the manual beginning with this sentence: "The signal ground and the frame ground are separated, however the power line is not isolated."...
The negative terminal of my battery is connected to the engine block (and to seawater through the propshaft) then from the block to the negative DC distribution panel.
The boat also has about 50 ft of copper foil running along the fiberglass hull and connected to an external lead keel. There is no SSB currently installed but I may install an SSB in the future and make use of the copper foil as counterpoise.
The NX-300 will be installed within 3 ft of both the DC distribution panel and an exposed portion of the copper foil.
Shall I connect the ground wire from the wing nut on the back of the receiver along with the black wire from the cable assembly to the negative DC distribution panel? Should I connect the bare wire from the cable assembly to the negative DC distribution panel also?
Thanks,
Pat
