[Elecraft] Firmware upload problem

[Don Wilhelm]

My opinion --
Since Joe W4TV is an authority on microHAM gear, I would say "use it at 
your own peril" if you insist.  Yes, there have been reports of success, 
but Joe says IT IS NOT SUPPORTED!  Please do not complain that you broke 
your K3 with a firmware load when you used the microHAM router., just 
get a good serial port (preferably hardware), follow the steps in the 
K3Utility help file and do a proper reload.

73,
