K-3: attempted loading 5.35 with wrong K3 Utility in error

[Elecraft mailing list]

Didn't realize that the K-3 utility I had was outdated. Started firmware download. Got message that MSU failed. The utility attempted to reload the firmware. Unsuccessful again.


So I closed the utility, downloaded proper version.


But now K-3 will not turn on completely. At power on, transmit light blinks continuously (red!) and message on screen MCU LD. But there is no communication through the com port, although K-3 Utility shows comport open.


I cannot turn K-3 off with power switch. I had to resort to unplugging at AC outlet.


Tried to reinitialize parameters, but unable to do so because even though I'm holding down the SHIFT/LO knob, when I turn power on, the blinking transmit light occurs and MCU LD message appears.


The utility does show comport open, but unable to connect.


Help greatly appreciated.

See the K3 Utility help file - it discusses recovery from a failed
upload (your problem).
