If you connect one end of a cable shield to ground, you create a
Faraday Shield ( Google it ) and having only one end connected to
ground prevents spurious current loops creating noise. You must of
course have one of the wires connecting the units at ground or 0 (
zero ) volts. That is, neither +ve or -ve with respect to (wrt)
the supply.

Hi all--
?
I'm a noob here with a just completed QCX 40 on the desk and
a QCX 20 just beginning
construction.? I've ordered the GPS kit with the intention of
connecting to the QCX's
via 4-conductor shielded data cable.? The GPS kit
instructions are pretty clear about
NOT connecting the shield to ground on the GPS side, but does
this also mean not to
solder the shield to the ground pin on the QCX side?
?
Many thanks in advance!? I learn a lot of stuff here
everyday.....in a good way. :)
