[Elecraft] Re. K3 Frozen update

[W5UN]

This is not a cabling issue, and no procedure listed in the manual 
works. I cannot get the radio to come on at all except to get the 
flashing red TX LED and the unbacklighted "MCU LD" indication when 
powered up. I have tried the Parameter Initialization procedure 
listed on page 61 of the manual, and I have tried holding the power 
button down for ten seconds while powering up. Neither of these 
yields any different results. Looks like I'm out of a K3 until I can 
call Elecraft tomorrow.



My K3 is frozen after attempting to load the latest firmware. The red 
TX LED is blinking and the display reads "MCU LD" with no back 
lighting.  No buttons respond, and removing and reapplying power 
brings back the same frozen state. I have searched previous emails on 
this reflector, and have found no workable solutions. Any ideas?

The K3 communicated OK with the computer prior to attempting the 
firmware update.
