[Elecraft] What Guage Wire for PS?

[Stuart Rohre]

The RIG should be the central point where DC return, earth ground, and
antenna shield or second conductor meet.  A star ground situation. The DC
path, should NOT travel over or depend on the other two.  That is an
invitation to RF feedback problems.  The earth ground would typically not be
needed in many portable operations, unless you were dealing with a long and
high antenna that develops static charge.
