[Elecraft] K3 / P3 firmware

[Dick Dievendorff]

To stop the K3 Utility, click the red X at the top right, or on the File
menu select "Exit", or click somewhere in the K3 Utility window and then
press Alt-F4 on the keyboard.  Just like any other Windows program.

 

After stopping the K3 Utility, turn the K3 off (remove its power plug), wait
30 seconds, then plug the K3 in again, press the power button, then start
the K3 Utility program again.  It should find the K3.  Then load firmware
with the K3 Utility.  Don't reconnect P3 power until after you've
successfully loaded K3 firmware.

 

I'm about to run out for a symphony tonight (Bach's Brandenburg Concerti!),
but I'll check on my iPhone from time to time.

How do I get the K3 Utility so stop attempting to contact the K3?
I'm sure the MCU is only partially loaded.
Every time I start the K3 Utility it just keeps trying to contact the K3.
P3 is unplugged.

When you power the K3 power on, you should expect to see MCU LD and the tx
red LED blinking because the MCU firmware needs to be completely loaded, and
you probably loaded a partial load earlier.
 
Just start the K3 Utility (but don't let the P3 power on) and load firmware.
The k3 Utility should find the K3 in MCU LD state unless the P3 was turned
on sometime after turning the K3 on.

  Thanks for the quick reply.
I followed that procedure, but when I press K3 power on I get only MCU 
LD and tx red led blinking.
How do I recover from this?

Disconnect p3 power plug. Remove K3 power by pulling its power plug. Stop

K3 utility. Plug k3 power back in and press K3 power on. Do not power on P3.
Start k3 utility and load K3 firmware. Then restore P3 power.

 
Newest P3 manual has this info

  Got new P3 and worked fine.
Went to load new firmware.
Gave error dialog that needed to turn off P3
Turned off P3
Now K3 is in mid stream says MCU LD
K3 Utility is just looping saying "Attempting to contact K3" at various
speeds.
Am I up the creek?
What is my next step to get K3 back?
