[Elecraft] k3 ERR DSE

[John McBee]

I was getting this error from the kxr3 menu when changing from ATU port 
to BNC port I have gotten this error a few times since I have installed 
the kxr3.  But all usually works.  The book said to try to reload the 
dsp 1 firmware and dsp2 firmware, so I opened up the k3 utility and 
tried to reload all firmware.  The k3 errored out on loading firmware 
and display said MCU LD and lost com port communications.   I could not 
turn off k3 by pwr button so turned off pwr supply, now can't get the 
rig to reset buy holding the shift-lo button in while pwr up k3.  So 
can't load new firmware yet.  Any suggestions..  I will keep looking in 
manual for a reset option.

Thanks
John
