[Elecraft] K3 / P3 firmware

[Dick Dievendorff]

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?

Start k3 utility and load K3 firmware. Then restore P3 power.
