Now I am in a situation where the K3 is stuck.  When I power it on, the LCD
panel is dark.  The red XMIT LED blinks and I am unable to establish
communications with the radio.  This is true after multiple power cycles
with minutes in between.

 

Have you tried the procedure "Forcing a Firmware Download" on page 44? It involves holding the power switch for 10 seconds. I presume this wipes out everything in the memory so you can start afresh.

If that fails, try a different computer or serial port.
