[Elecraft] k3 MCU flashing TX lockup

[Gary Gregory]

Hi Guy's

I am using a serial cable, not had any problems b4 with downloads. Tried to
download latest Beta when it all went south.

Repeated on/off has not helped so far.

Let me get this correct in my head.

1. turn off linear power supply.
2  wait 10 seconds.
3  Reboot windows xp pro

Should I start the utility 1st?...(I am using latest version) or the radio?

I am seeing the radio come on when I press the button and the led's are
bright. If I keep holding the power button the radio comes on, no backlight
just flashing red tx light and MCU LD on the display.

Thanks guys.
Gary
I just got lost in thought............. It was unfamiliar territory
