Not at all. Exchange the DB9F ("computer") and DB9M ("radio")
and it will be easier. The SteppIR controller will connect to
the K3 via the long 2-wire connection and the short leg will
be set up as a connection point for a standard serial cable
from the computer, USB to serial converter, or the CAT cable
from a microHAM Interface.
Just remember to set the K3 "AutoInf=On" so the SteppIR gets
the necessary frequency data when a logging program is not
polling.
