[Elecraft] KX3 has died

[Dave Sublette]

It is not looking good, folks.  The RS232 adapter which drives the KX3 is
not flashing any more as it usually does.  The KX3 Utility returns "KX3 not
responding" when I test the link.  All cables are properly connected.  It's
been working perfectly until earlier this evening.

I think it is due for a trip back to Elecraft.  I will call them tomorrow.

Thanks for the help.  I did find the Help column and the troubleshooting ,
etc....

I had already done all of those steps and got nothing but the "not
responding" error.

I'll let everyone know what happens.

73,

Dave, K4TO
