Tom,
I don't believe there are any explicit instructions - BUT -
If you assemble the KAT100-2 and put it into an EC2 enclosure, the
mating of the KPA100 should be fairly obvious. There is a header on the
KAT100-2 board to accept the ribbon cable from the KPA100, a 2 pin
header for the RF input connector and another 2 pin header for the DC
power. (BTW, Elecraft offers a kit to change the KAT100-1 to a KAT100-2
which includes the required headers).
For the external connections, you need only 3 - 1) DC power to the
KPA100 (the KAT100 receives its power from the internal cable from the
KPA100. 2) The control cable is just like that one shown in the manual
for the KAT100, and plugs in just like the normal KAT100 cable (that is
where the KIO2 is required in the QRP K2). 3) Use a short piece of coax
with BNC connectors between the QRP K2 (either the ANT OUT jack or with
the KAT2 installed, the ANT1 jack from the KAT2). The other end of the
coax connects to the AUX RF input jack on the KAT100 rear panel.
That is all there is to it - set the menus just the same as if the
KPA100 was installed internally.
If the KPA100 is installed in the EC2 enclosure without the KAT100, the
situation is only a little different - one must install a BNC input jack
on the EC2 back panel and connect the KPA100 input coax to it (order the
mating header from Elecraft and solder it to the back of the BNC
connector for the easiest installation). The control cable (just like
the one used with the KAT100) plugs between the KIO2 and the KPA100 AUX
I/O, and of course DC to the KPA100 rear panel power jack. That is it,
not really difficult at all.

Don,
I now have all the pieces to do this (remote the KPA100 and KAT100-2). I have
seen many discussions on this subject, and I know there are directions out
there for doing this. Is there any one set of directions that is best in terms
of describing all the steps? I don't necessarily need photos, but I need
something that covers everything that needs to be done.
