[Elecraft] K3 firmware upgrade via Microham MKII

[John Gaynard]

Thanks.  Guess I'll use the serial cable.  Not worth the risk of failure.

No.  

You might get lucky with a complicated set-up;  set Radio to 
"No Radio," use only one CAT port, set the K3 to 38,400 bps and 
set the K3 Utility to "keep speed at 38,400 bps.  However, the 
chance of errors is so high that it is not worth the risk. 

I keep a real serial port/cable handy for firmware updates and 
I've still had intermittent upload failures.
