[Elecraft] KX3 Firmware update trouble

[Bob N3MNT]

Have you tried this.
If you accidentally load an old or incompatible
firmware version and find the KX3 unresponsive,
do the following: (1) Unplug the KX3 from the
power supply. If internal batteries are installed, also
remove one battery. (2) Plug a power supply in (or
reinstall the removed battery). (3) hold the KX3’s
BAND- and ATU TUNE together for about 10
seconds, after which you’ll see the TX LED flash
(you’ll also see MCU LD on the LCD). (4)
Connect the KX3 to a computer and run KX3
Utility, which will load new firmware.
