[Elecraft] KRC2 setup for Icom

[Don Wilhelm]

Rich,

What baud rate are you trying to use?  The KRC2 is limited to 19.2k.
Double check the jumpers for the RS232 port.
Follow the instructions in the manual to download the firmware.
You only need to connect the KRC2 to the computer for firmware, but you 
can connect the serial port on the ICOM through the KRC2 (but the speed 
needs to be limited to 19.2k.

I see Jack Brindle sent a response - he is the designer and therefore 
the expert.
