[Elecraft] KIO2 "Gotcha's" and "Trip Wires"?

[Logan R. Zintsmaster]

My recommendation is to use heat shrink tubing on ALL of the pins,
including those not used. Radio Shack sells a blister pack with an
assortment of sizes that will have the size you need.

The Aux Bus is the one that you need to worry about the most (replied
the voice of experience.)
