[Elecraft] firmware upgrade snafoo

[Don Wilhelm]

Sam,

It is normal for the K3 display to go blank following each piece of a 
firmware load (the red TX light blinks once too).  It should come right 
back again  and proceed on if you just wait.
If one panics and presses buttons, or manually cycle power or does other 
clicking on the K3 Utility window, yes, it can get stuck, and you have 
to do the "Disconnect Power Thing".
Is there any chance that you have a flaky USB to serial adapter?  Try 
using a computer with a real serial port. If that is not possible, try 
another adapter and be certain you have the latest drivers loaded.

I have loaded firmware many many times as a firmware field tester, and 
have never had a problem, except once when I did something stupid during 
the firmware load.  I have always used a real serial port which helps a 
lot too.
Just start the firmware load (use normal mode in K3 Utility and click 
"Send All Firmware to the K3"), then let it run to completion.

73,
Don W3FPR
