Bill,

I would assume that you have the LDG interface cable for the Icom.  
Unfortunately, LDG does not make a similar cable for the Elecraft K3.

You could go to a lot of trouble and reverse engineer the LDG cables and 
then adapt them to the K3, but for the time and effort involved, it 
might be more economical to just spring for the KAT3 - it depends on how 
much you value your time and effort.  Yes, creating your own custom K3 
to LDG cable may be a fun exercise, it may or may not be economically 
feasible depending on the value you place on your time and effort.

73,
Don W3FPR
