[Elecraft] hand/footswitch keying for KX2

[Chris Tate - N6WM]

Greetings to the Elecraft brain trust.  I am in the process of putting a couple of Island expedition kits together.  The KX2 fits the bill in the TOTAL portability grab and go kit department. I have a question for the brain trust while I try and pull an entire parts inventory for my mini kit.

What is the preferred method for hooking up a foot switch or small hand switch to the little guy?  I am trying to remember what I did with the KX3, I think there was an amp cable that I was able to key via an RCA plug.  Is it the same deal with this?  is there another way of doing it?  Want to be able to use a headset/boom mic, sometimes Caribbean beaches can get a bit noise with chatter and such..

Just curious what the solutions are out there.. and I am sure there is probably more than one.
