7.21 CHASSIS GROUND
This is a thumbscrew for attaching an earth ground to the chassis of the radio. Grounding
is the most important safety enhancement you can make to your shack. Always ground the
FLEX-6000 to your station RF ground using high quality wiring with the length being as short
as possible. Braided wire is considered the best for ground applications. Your station
ground should be a common point where all grounds come together. You will likely be
using a PC and a DC power source so be sure to ground these devices together as well.
