[Elecraft] K3 Froze

[David Carlson]

My K3 froze up while downloading in The K3 utility program. The LED shows "MCU LD" and the red TX light is blinking under the power switch. I can not turn the power off with the power switch. I have to turn off the power supply. The K3 utility program can not communicate with the K3  so I can't reinstall the firmware code, however the P3 utility program can connect. I have tried turning off the K3 and then turning it back on holding the "shift/lo" button to reset. That does not work. I did download the latest K3 utility program.  

Any suggestions?  Thanks
