[Elecraft] COM port not working

[Don Wilhelm]

Gary,

If other attempts (checking computer, ports, cables, etc.)  fail, 
contact K3support at elecraft.com and they can give you a couple of points 
to measure in the K3.  Should the K3 be the fault, and if you are 
capable of SMD IC replacement, then they can send you the RS-232 to 
TTL/CMOS converter IC and you can replace it.  If you are not capable, 
you may be able to exchange the KIO3 board.

73,
