[Elecraft] K3 - stuck at MCU LD we upgrading software

[N2TK, Tony]

Hi Bill,
I did that. Also had to go into K3 Utility and turn off the port then turn
it back on. Then things loaded fine.
No idea why it happened. First time I had a problem changing firmware with
either K3. All my Ham stuff is tied into a work station that has battery
backup so that should not have been the issue. But who knows. 
Back in business.
73,
N2TK, Tony

Unplug the radio from power. Unplug the USB cable  

Re-boot computer plug in USB and then power up the radio. It should start
the FW load.
