[Elecraft] K3 firmware catastrophe

[Matt Zilmer]

Hi Dick,

You may have tried this, maybe not -

Try powering on the K3 by holding down the POWER switch on the front
panel for about 10 seconds.  You should see MCU LD on the display, and
the display may not be backlighted (look closely).

If you see the MCU LD annunciator, it means the K3 is ready to accept
new firmware.  Start up the K3 Utility and make sure it's connected to
the K3's COM port.  The utility should indicate the K3 is ready to
accept new firmware.

If the MCU LD text didn't appear, it'd be best to email
K3support at elecraft.com, so that they can assist you.  

Luck shouldn't be a factor, but good luck to you anyway.  I've had
this happen a number of times in the last eight years with my K3, and
the method above always worked.  If a firmware load doesn't complete,
the K3 reverts to its bootloader every time.

What I suggested is in the K3 owner's manual.

73,
matt
