[Elecraft] DX Doubler/K3 issue

[Joe Subich, W4TV]

Bonding the chassis of each transceiver to DXDoubler is 
recommended by TopTen Systems but their application note 
also says that bonding alone may not always be enough. 

I've always recommended bonding every piece of equipment 
(including the computer) to a single common reference 
(ground) point, generally the same point at which all 
feedlines enter the shack.
