[Elecraft] Best way of running 100W?

I did exactly this with my K2/100. I put my KPA100 in an EC2 enclosure with
a KAT100 and bought the battery option, KAT2 ATU and KIO2 for my base K2. It
allows me to (as Ron pointed out - the no screwdriver option) unplug a
couple of cables and take my K2 portable in 30 seconds. Plug the cables back
in and I'm running QRO from the shack again.

Lyle Johnson, KK7P, has a detailed explanation on his website on how to
accomplish this: http://www.kk7p.com/k2kpa100.html

I opted to buy a KIO2 module for my basic K2 so that the split would require
a minimal amount of work and just seemed cleaner to me than having to
manufacture a custom cable from the K2 to the EC2 enclosure. (The custom
cable is need to bring the AUXBUS signals from the K2 over to the KPA100.
Using the KIO2 simply requires using the existing cable you built with the
KAT100, provided you have one). Lyle shows you how to do it both ways.
Toward the bottom of that page, he details how to make the split with a KIO2
module in the K2. YMMV.

As Ron pointed out, this is not an Elecraft mod nor do they support it. But
many, including myself, have made this modification and been very happy with
it.

Don't hesitate to ask questions about it - it really is pretty simple, looks
good and for me, makes it a no-brainer to go from shack to portable in
seconds.
