[Elecraft] Elecraft K3s, etc. bonding, question for K9YC.

[Dave Cole]

Jim,

In looking at your slides, slide 105, (thanks for sharing the 
presentation BTW), it strikes me that the coax cable braid running 
between radio/amp/tuner/antenna panel, would act as a bonding 
connection, so I would not need to add a large wire between those items. 
  Is this correct?  If not, why not?

73, and thanks,
Dave (NK7Z)
