[Elecraft] K3 not communicating with PC

[Roger Dallimore]

Hi all,

I can't work out why my K3 has stopped communicating with my PC. Besides 
the K3 utility I'm using HRD. Up to now I've used the KUSB which has 
worked fine, it was bought with K3 #191 at the same time.  I reinstalled 
the drivers checked Baud rate (38400), swapped ports etc but still no go.

I then tried a standard RS232 instead, but still it does not work.   

What am I missing here? Any help would be appreciated (my email is set 
to digest mode).
