[Elecraft] KX3 has died

Sun Dec 9 22:11:06 EST 2018

OK -- time for a confession.  I'm updating using a MAC.  I don't think that
has anything to do with the problem.  It has worked perfectly for four
years.  Doesn't say that something couldn't have died.  But the MCU LD and
flashing Tx LED on the KX3 says there is a firmware error and I don't think
a failed interface cable or computer would cause that.

I'm not a computer guru.  It will be interesting to see how this plays
out.  Thanks to all for helping.  This is a knowledgeable and friendly
group to deal with.
