Tad,
For Field Day, you may want to add a strap between the KX3 and the
KXPA100 to reduce noise pickup on the cables between them. If running
on batteries, that should be sufficient. If running on a generator, you
COULD connect a heavy wire between the KXPA100 and the ground rod for
the generator (do not drive a separate ground rod because it can cause
an AC hazard). As for lightning protection, the normal Field Day
precaution that I know is to disconnect antennas and turn off the
equipment when that is nearby lightning.
For your mobile installation, I don't think many mobile hams do any
grounding. If you feel you need it, ground to the vehicle with a strap.
A mobile station is "battery powered" and a ground is not normally needed.
Remember that a ground is only for AC safety and lightning protection,
and normally demands that a connection to Mother Earth is needed and
that any extra driver ground rods must all be connected wwith heavy wire
to the Utility Entrance ground rod.
The only equivalent in a generator powered Field Day installation is a
ground rod at the generator. There is no equivalent for mobile operation.

I am planning to use my KX3 and KXPA100 powered by Budipole PowerMini
and LiFEPO4 battery for field day this year and have a question about
grounding. When I am using them both at the home station they are
grounded to each other and every other piece of equipment in the shack
using a ground bar and copper straps. When I use my KX3 by itself
mobile I have never grounded it and never had an issue. Is there
anything special that I need to do do when I hook the KX3 to the KXPA100
while mobile, and what is it? and or what do the rest of you do when
running mobile with a KX3 and KXPA100 for grounding?
