[Elecraft] K3 configuration or control software?

[Eric Rosenberg]

Back when I last owned a K3 (2009?), I had a piece of software that would,
among other things plot the SWR of the antenna attached to the radio. 

 

Now that I've picked up K3, I'd love to find the software in question. It's
not the current Elecraft K3 configuration program, the Win4K3Suite, or
N4PY's software packages. 

 

Is anyone familiar with the software I'm thinking about?  

 

Thanks,
