[Elecraft] KX3 bricked by F/W upgrade attempt

[Bill Frantz]

I remember a problem I had a year or so ago where I was using 
the K3 (Mac) utility to load all the K3 microprocessors' 
firmware. I was failing on loading one of them and restarting it 
did not cure the problem. I got around the problem by loading 
just that specific piece of firmware. I vaguely remember seeing 
a bug fix for the utility that seemed to be my problem, but I 
could have misinterpreted the README. I haven't had the problem since.

Bottom line: Try loading just that piece of firmware. Then load 
the others separately if they aren't up to date.
