[Elecraft] KPA500 AUX input

[Guy Olinger K2AV]

I think where you are getting to is dumping the burden of
understanding every possible piece of peripheral gear on Elecraft.
(And blaming them if they don't, or give you some errant advice?)

It's fine if they want to answer, but in the end, making ANY
transceiver, a K3 or a Yaesu 5000, or ..., work with a given PC and a
given operating system and drivers and peripheral gear is the OWNER'S
problem.

Elecraft is responsible for what programs they distribute and drivers
for stuff they sell, but after that, it's *US* that have the controls.

Personally I want Elecraft spending their time on THEIR stuff.
Debugging other manufacturer's software and hardware is on the road
that leads to commercial failure.  The street sign on that road is
"NOBODY WINS LANE".

73, Guy.
