Here are some photos of my station setup for the 2011 CQWW DX CW contest.
I prefer to use two PCs with an interlock to using one computer only. This gives redundancy, in case of problem, and is easier for my brain to manage than trying to remember key strokes and software. My homebrew headphone switch in between the keyboards controls the audio, and I use one paddle that can be switched to the other radio by pressing a foot switch. Not much automation, but it fits my style. I am fortunate to have two computers set up all the time; one for work and the other dedicated to radio.
