[Elecraft] KRC2 setup for Icom

[Rich]

Does anyone have any experience using the KRC2 with an Icom radio?  This 
is a working KRC2 that was on a K3 at one time.

To start I cannot get the KRC2 to connect to my PC.  I have used 
straight through cable, Null modem Cable and a USB to Serial Cable.  I 
have run the program on an old XP laptop and my Win10 machine.   I have 
even used a "real" comport.  None of those configurations will connect 
to the device.   The DL switch is set properly.

The KRC2 passes all of the manual button press tests.

I have the jumpers set for ICOM on KRC2 board.  The ICOM is sending the 
band voltage to the unit as measured with a Volt meter.

Do you really need the computer to make it work?  I am thinking that is 
mainly for firmware and antenna relay settings

I am just trying to control a 419B bandpass filter.

Any thoughts?
