Hi Martin!

First: Depending on your mechanical/electrical skills, you dont need 
either the KIO2 nor an EC2. - Yes, all what you would need from an extra 
EC2 would be the two side panels, the tilt standup, the feet. AND the 
2D-fasteners! -Stingy as I am, I ordered my KAT100-2 without an EC2 and 
build it myself from 1.5mm aluminium from my local supplier, the 
fasteners were made from an 6x6mm u-shaped brass profile and the paint 
was mixed at 'Bauhaus' - 1/4 gallon, enough to paint homemade EC2s for 
the rest of my life;-). But, if i would have thought before about the 
time needed - i *would* have ordered the EC2!!

KIO2: Well, if you could manage to get the needed signals from the 
controlboard to your external amp/tuner, no KIO would be needed. But you 
should look for an shielded calble if you won't risk to get spurious 
emissions from the control logic into your receiver. And, if you also 
can get the ttl-Interfacesignals to the KPA you would also profit from 
the build-in RS232 inside the KPA.

- The philosophy why the elecraft guys probably won't recommend this is 
just that if you have an extra KIO inside your K2 you can use it 
independent from your external KPA/KAT.

My own approach is quite similar to yours: K2 with no KIO and KAT100 in 
(selfmade) EC2 whitch will also be housing for a later planned KPA100. 
For me, serial I/O will just be needed when I am at home, not for field 
use, so I dont need the KIO2.
