[Elecraft] Remotely located KAT500 in the ARRL 10m contest

[ab2tc]

Hi all,

The contest isn't quite over, but the onset of full darkness in CNY has
pretty well closed the band for the day.

I started the contest Friday night with just a G5RV connected to the tuner.
I added two more antennas, resonant dipoles for 10 and 15m Saturday morning.
Once the tuner learned my frequencies I could make an instant change between
the G5RV which required lots of intervention for its raw 12:1 SWR and the
dipole which had less than 1.5:1 across the phone band. The tuner decided to
add 100nH inductance only and it dropped the SWR to 1:0 across most of the
phone band. I had a blast with it and discovered much to my surprise that
the G5RV almost always equaled or exceeded the performance of the dipole.
Both are at similar heights. The ability to do an instant switch between the
two including switching in the tuning elements required for each is
invaluable. The setup here is:

KAT500 located close to the antenna feedlines coming down in the yard. The
only communication with the KAT500 is the serial link via Ethernet serial
server by B&B. No attempt to hook up the aux cable over that distance (100+
feet). With this setup I can control the box from anywhere I can connect to
my LAN.
