[Elecraft] Recovering from failure of KX3 firmware rev. 1.79 load ("ERR DSE", etc., shown on KX3 LCD)

[Wayne Burdick]

If you see "ERR DSE" on the KX3's LCD after attempting to load rev. 1.79 firmware, and/or KX3 Utility reports a load failure, try the following:

1.  Tap the KX3's DISP button enough times for the ERR messages to go away.
 
2.  On the KX3 Utility Firmware tab, View Menu, check “Advanced Mode”.  Check boxes should appear in the Firmware Revisions group.  

3.  Check "Load DSP" but not "Load MCU."  Click “Send Checked Items to KX3”.
 
The DSP should now load.

If you still have difficulty, contact customer support. Note that we're also going to update KX3 Utility tomorrow to a more recent version that results in a cleaner load process.
