[Elecraft] Elecraft KX3 Utility for OS X Revision 1.14.4.11

[KE0AFG via Elecraft]

Are you using the Elecraft USB to serial cable?  - yes, the KXUSB supplied
with the radio

Can the utility find the serial port in the "Port" tab? - yes, it shows
"usbserial-A703096P"

Is the plug all the way into the jack on the KX3? - tried several times, it
appears ok. 

Are you using the correct jack? (Getting desparte here.) - it worked
previously.
  
   After selecting the usbserial port and trying "Test Communications"
button - error msg "Connected device does not appear to be and Elecraft KX3"

went to page 25 of user manual, under "Forcing a Firmware Download", I did
the following;

Forcing a Firmware Download
If you accidentally load an old or incompatible
firmware version and find the KX3 unresponsive,
do the following: (1) Unplug the KX3 from th
e
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


now my KX3 has a flashing red TX light and "MCU LD" on the screen. How to I
get it back to a working radio?

Thanks,

Terry, KE0AFG
