[Elecraft] OT: Software to do block/wiring diagram?

[Bruce Thompson]

Sorry for the off topic post but I know the knowledge is out on this list.

 

I'm looking for some software that I can use to create block diagrams for
electronic setups.  Station wiring is just one example.  I would like it to
be able to show things like grounds and pull up resistors too but it doesn't
need to be able to do full schematic capture or PC board layout.  Willing to
pay a few bucks if that helps.  Any suggestions?
