[Elecraft] Help -- stuck in MCU LD

[Grant Youngman]

Yes, It's the Mac version.

It fails.  Every time.  Usually, but not always, once I restart  
everything, I can use the "test comm" page to check, and get a good  
test.  Then when I try loading firmware, it fails.

11:47:29 K3 is running main program. RS232 38400 bps.  -- after this  
message the yellow led is on solid
11:47:29 New firmware is available for your K3
11:47:34 K3 is not responding. -- after hitting "send all new firmware"
