Frank,
The USB to serial port may have changed (computer problem).
Remove the USB end of the KXUSB and reboot the computer. When the
computer boot process has finished, plug in the USB connector and see
which COM port is assigned to it.
If you cannot tell, open Device Manager - then remove the USB cable
again - which COM port goes away? The plug it back in and see which COM
port is assigned.
Use that COM port number in KX3 Utility and it should recognize the KX3.
Most problem of this nature are due to the computer, and not the radio.
If that does not solve the problem, then look in the manual or the KX3
Utility Help file for "Forcing a Firmware Load" - try those steps,
reload the firmware and all should be well.
73,

Folks, I just updated my firmware on my KX3 all went well.
I removed the Elecraft cable and then a few minutes later I reconnected the
cable back to the radio.
Now I when I start the Elecraft KX3 Utility and “test the communications”
button, It says KX3 not responding.
