Subject: [Elecraft] K-3: attempted loading 5.35 with wrong K3 Utility in
error

Didn't realize that the K-3 utility I had was outdated.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.


73,
