Randy,
MCU LD is a normal display by the KX3 when waiting for firmware to be
loaded.
It may be that the KX3 is just sitting there waiting for the computer to
feed it some data.
Because this all started during a firmware update that stopped midstream
for some unknown reason, I would suggest you be suspicious of the
computer, the adapter cable and anything else associated with the serial
connection. You may even want to try reloading the driver for the USB
to serial adapter.
It would be a shame to send the KX3 back to Elecraft only to discover
that there was a problem at the computer end. If you have another
computer (or can borrow one) try loading the USB cable adapter driver
and KX3 Utility on that computer. If you have an XG3 signal generator,
try using the same cable and the XG3 Utility - the cable for the XG3 and
the KX3 are the same.

As I stated. I have read the manua (RTFM)l and tried the EEINT proceedure
stated there. It will NOT respond to a Parameter INIT. It still says "MCU
LD." I have tried all documented solutions to get it back right. I realize
that I would have to recalibrate or load original config file after but I
cannot even get there....
