[Elecraft] OT: Software to draw electical block diagrams?

[brucet]

I asked this once an can't find my silly notes.  What was the name of that
software you guys are using to draw electrical block diagrams?  I used it
over a year ago and my machine blew up and I lost it.  Time to get back to
that project but now can't remember its name.

 

Thanks!
