[Elecraft] KX3 COM Port Not Working

[Don Wilhelm]

Do you see the COM port listed in the Device Manager listing without any 
exclamation mark?  If not, then your computer and the FTDI driver needs 
to be addressed first.  You can download the driver from the Elecraft 
website, although in my experience, Windows 7 or Windows 10 will load 
the correct driver.

Once you have the COM port that is assigned to the USB adapter, then set 
K3Utility (KX3Utility) to use whichever port is assigned.  If you change 
the USB plug, expect the assigned COM port to change.

Test Communications in the Utility applications should reveal connection 
or no connection.
