Mike,
You do not have to do much at all.
Download the latest KX3 Utility and then update to the latest firmware
and operate.
Then at a more leisurely pace, go to the Elecraft website and review the
KX3 hardware updates available - you do not have to do any of them
unless you want to do it or have a particular problem associated with
those upgrades.
Also review the KX3 Application Notes and do any of those that you would
like. There is one that you should check on before installing
batteries, and that is the one dealing with the battery holder mounting
screws - you may or may not have the problem mentioned.
You might also want to apply some epoxy glue around the input power
jack, especially if you are not using the right angle power plug. The
power jack on very early KX3s were not glued and the power jack could
break away from the board causing intermittent power problems. I did
have that problem with mine.
I have the first KX3 that came off the production line and have not yet
found the need to do any of the hardware upgrades, but I have done some
of the procedures in the application note, not because it was needed,
but I wanted to 'walk' through the procedure for the experience.

I purchased a KX3 when they were first introduced. Then life got in the way
and all non-essentials were put on hold. Now things have improved and I've
been thinking about breaking out my "brand new" KX3. What have I missed in
my absence, and whats the best way to bring this beauty up to speed? Thanks
in advance. Mike Eddy WA7YET
