[Elecraft] sharing K3 RS232 to CAT and Remoterig

[Jorge Diez - CX6VM]

Hello Fred

I lost automatically antenna change because I needed to remove my CAT cable
from K3 to connect remoterig. Of course if I removed remoterig RS232 cable
and connect CAT cable all is OK as I had it before connecting remoterig

That switch A/B is not an option for what I am looking for,  I need both at
the same time

thanks!
Jorge
