[Elecraft] KX3 Serious Errors in the Manual

Jim is quite correct that a radial or a counterpoise should not be 
referred to as 'ground'.  To do so further confuses the use of "ground" 
by many hams.
At least the English use words to differentiate between "earth" and 
"ground" (but there is still the lack of differentiation for 
counterpoises and radials).

One needs to consider AC grounds, Lightning grounds, and RF Grounds 
separately.  The only two that have a relationship with driven ground 
rods are the AC Ground and Lightning Ground.  RF ground (and RF return 
path with respect to the antenna) is an entirely different 
consideration, and IMHO should not be called "ground" because it rarely 
is a "ground".

There is further confusion about what a "ground" is.  Driven stakes do 
not constitute an RF ground as one example, and a simple driven stake is 
not adequate for lightning protection even though it may provide some 
ESD protection.

Yes, I have given this "rant" several times on this reflector and 
elsewhere.  Do you have your driven ground rods connected to the utility 
entrance ground rod with a large conductor (#6 or larger)? If not, you 
may have created a safety hazard instead of any protection.
