[Elecraft] auto-disconnect antenna relays? (KAT100 related)

[Chris Kantarjiev]

I've just replaced the 1N5711 SWR diodes in my KAT100 for the Nth time. It's annoying, but I guess 
it's not annoying enough to cause me to disconnect my antennas every time I turn off the radio!

Here in "northern" California, we don't have many thunderstorms, but apparently we get enough wind 
static to damage these diodes once every year or so. I really wish there was an idiot-proof way to 
disconnect the antennas without any intervention on my part!

A small box that was powered from my 12v distribution panel and has two suitable relays in it would 
be welcome. I guess I could make it myself, but I wonder if anyone else has already done so, in a 
way that integrates cleanly to the KAT100 outputs? I wouldn't want them in the KAT2, since I operate 
from battery at times. But when I'm running the KAT100, I am using more power than I have battery ...

(Does the K3 have such relays in the output circuitry?)
