[Elecraft] Extra Protection For KPA500?

[Bob McGraw K4TAX]

With this regard, Jack Brindle is absolutely correct.  The system as 
designed is more than adequate to safely and correctly interface the K3S 
to the KPA500 and then to the KAT500.  If the operator chooses not to 
use the system, as designed and intended, I view they they become a very 
underpaid design engineer with unknown project outcome.  Using another 
computer/micro-controller only adds an additional element for failure.  
There is no way to make the system idiot proof except to remove the 
idiot from the equation.

Just use the cables as required and detailed in the manuals {which one 
must have and read} and then follow the instructions in the manuals.   
Don't give me the crap "well it doesn't operate like bla bla bla".  That 
is correct, it shouldn't and it doesn't.    It is an Elecraft and the 
manual explains how it is to be utilized, and the methods do work.   I 
sit here daily in front of my K3S, KPA500, KAT500 and P3 with joy and a 
smile on my face realizing how efficient the system integration works.  
It is more like having a 500 watt transceiver that covers 160M - 6M and 
works any mode I desire.   Now, that ain't bad!
