[Elecraft] K3 comatose

[Ken K3IU]

Have you tried the Help menu item in the K3 Utility Program? Here is one 
thing is suggests...
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


  Forcing the K3 into "firmware load required" mode

To force the K3 into a state that it requires a firmware download,

    * Unplug the K3 from its power supply for at least 5 seconds.
    * Plug the power supply back in.
    * Press and hold the K3's power switch in for about 10 seconds until
      the red TX LED begins to flash.
    * Click "Check Versions Now" on the Firmware page.
    * Click "Send All New Firmware".

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
