[Elecraft] GND Connection Between KX3 & KXPA100

[Eric Buggee]

     Hi all,

     One additional comment regarding grounding for RF interference, 
extraneous noise & elecrical safety considerations is that the preferred 
method for grounding should be:

     Single point grounding, ie all rig & amplifier ground connections 
should be taken from a single point, (shack grounding buss).

      Relying on "daisy chain" grounding for example: through coax 
cable(s) & their connectors; Rig > Amp > tuner > tground point can be 
the source of intermittent RFI & distortion

     problems that can be difficult to nail.  This approach to grounding 
should NOT be used for the foregoing stated reasons.
