[Elecraft] Using KAT500 With Antenna Switch

[Ian Kahn - Ham]

Thanks, everyone, for the feedback. Perhaps a bit of extra explanation 
is order, so I make sure I'm getting/understanding the right info:

 1. My father-in-law and I share the same shack, each with our own
    complete setups.  Since we both have transceivers, tuners, amps,
    etc., running more coax into the shack is to be avoided.  It just
    gets too messy, and we want to avoid any possibility of
    interference, other than what we already know about.
 2. I use the Hexx-Beam on 20-10; I use the dipole on 40-80.  I don't
    use the dipole above 40m, but it is capable of 80-10m operation.

So, if I understand the comments correctly, as long as I switch antennas 
at the remote switch before injecting RF into the path, the KAT 500 
should be able to detect which antenna I'm on and use stored-memory 
settings, thus resulting in a quick tuning cycle, after the initial 
tuning setups.

If I am misunderstanding the comments, someone please correct me.  
Whatever the answer is won't put me off my purchase; I just want to make 
sure I have a correct understanding of what will be going on.

Thanks and 73,

--Ian
