[Elecraft] K3 RS232 no data out

[Pete Smith]

Hi Monty - what is odd to me is that in 20 years of computer-aided 
operating, this is my first RS-232 failure, and it wasn't even that 
impressive a storm.  Closest hit was ~1000 feet.  Anyway, it's an 
expensive lesson.  I wonder if making *really* sure of a good common 
ground between radio and computer might also help (?).
