[Elecraft] K3 / P3 firmware

[Dick Dievendorff]

The newest P3 Owner's manual revision (A5) covers this:

K3 MCU LD Error
If you attempt to download firmware to the K3
while the P3 is turned on, the K3 may become
unresponsive in bootstrap mode (MCU LD displayed
on the K3’s LCD). Clear the condition as follows:
 Turn the P3 off.
 If the P3 is configured to turn on automatically
when power is applied to the K3, disconnect
power from the P3’s rear panel. It’s important
that the P3 remain off throughout the
procedure.
 Disconnect power from the K3’s rear panel.
 Exit the K3 Utility program at your computer.
 Reconnect power to the K3’s rear panel and
turn the K3 on. Be sure the P3 does not come
on with the K3. If it did, repeat the procedure
from the beginning and be sure to unplug the
P3’s power cable. It won’t work to turn the P3
off once it has turned on.
 Restart the K3 Utility at your computer, and
reload the firmware.

  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?
