[Gregg W6IZT]

AutoInf=On? I just scanned thru menu and config. Where do I find this
parameter?

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.
