[Elecraft] K3 Utility Reload issues

[Jim McDonald]

I have a microKEYER II but rather than disconnecting the K3 from it I use a
DB9 A/B switch for firmware updates.  The K3/P3 is connected to the switch,
and the A position is connected to the MKII and the B position is connected
to a serial port on the computer (really a COM port on an Edgeport/4).

That way no time is spent re-cabling, and it's just a flip of the switch.  I
flip to the serial port on the Edgeport every time I use the K3 or P3
utility, which is fairly often as I like to save a new configuration file
after I change a menu selection.

I found a Belkin DB9 switch on eBay.

Please carefully go through the steps listed in K3 Utility Help,
Troubleshooting, MCU Load Failure.

If you are using a different COM port than you were using before, be careful
that you've selected the correct new COM port

I tried to download latest K3 utility version 1.12.10.10 and ended up with
dead radio.  I tried the help advise and their recommendations ending with
still  nothing working.  I disconnected MicroHAM  keyer and the power  to
K3, connected radio direct to computer with  RS 232 outlet direct to COM
port, turned power off to radio, reapplied power and tried to reload
software and still only flashing TX LED with MCU LD showing without back lit
screen.  Any suggestion appreciated.
