[Elecraft] K3 and FLDigi

[jsdroyster at nc.rr.com]

Dave suggested the HamLib option in fldigi as follows
Next, in Fldigi in Config\Rig control, choose the Rig tab, then Hamlib. 
In Hamlib, check the box in front of Use Hamlib at the top.  In Rig 
choose Elecraft K3/KX3 (Beta).  In Device, choose your com port. Below 
that, set the Baud rate to 38400.  On the left side, check the box for 
PTT via Hamlib command. 

Alternately, you can elect not to use either Hamlib or rigcat, but simply use VOX in the K3.  This frees the cable for something else, but it does disable frequency tracking.
