Steve,
I recently took a lighting hit that took out quite a bit of my
equipment. I have a WISP antenna on my tower and I feel it came through
the ethernet to the computer then to all devices connected to the
computer via the usb ports. It took out my I/O card in my K3S, all
three of my Green Heron RT-21's and a USB port on the computer. It also
took out the 4O3A antenna switch was connected to the network via an
ethernet cable.
After a bit of research I am going with Green Heron's GH Everywhere
products. The only thing connected to my operating desk from the towers
will be a single coax cable (which passes through a Polyphaser at the
entrance bulkhead)
I'll be able to control my two stack matches with one of the GH remotes
with the 8 relay card installed. That sounds like what you need. If
you need more than 8 relays, purchase a 2nd remote with another 8 relays.
I was a little hesitant at first, but after setting up one of the
remotes, it wasn't difficult at all. I like the graphic interface on the
computer which can be controlled with a mouse click or hot keys. I will
no longer need the stack match control boxes or RT-21 rotor controls on
my operating desk. My operating desk is now clutter free.
The three RT-21's are being repaired and will be upgraded with Jeff's
wireless cards so I won't need to connect them to the computer with a
USB cable. I'm also installing a couple Select 8 switches at the towers
which will not require control cables, just 12v down the coax.
Wish I had done this a long time ago.

Hey guys,
After a recent lightning event I find that my 20M 3-high stack
controller got zapped. This is an IC based homebrew design that a
friend made for me in the 90's.
I'll be able to swap in the 10M controller as a temporary fix, but
going forward am wondering if there is an easy commercial replacement
available, maybe with a bit more flexibility (more relay outputs).
I currently need to be able to control 7 relays in 7 programmable
different combinations (all involving either 1, 5, or 6 of the relays
to be energized at a time, per the K3LR article from the 90's).
My current control boxes have 7 buttons each of which can direct
access the 7 relay combos. I much prefer this over any rotary control
switch.
Anyway, I know this is a simple task for a little Arduino box and
relay controller - is there anything out there that is (almost) ready
to go?
Thanks,
-Steve K8LX
