I've written a general purpose RF circuit simulation suite (https://sites.google.com/site/circuitmason/
) that I'm sharing for free. My code implements a complete GUI path from schematic to simulation to layout; I think it is well documented with several examples. I think a lot of amateurs could use this in their projects, and colleges and high schools could use a tool like this to augment their programs. Simulation using free software plus an existing computer infrastructure is a lot cheaper than equipping an RF lab, and provides many of the same benefits.
I have a long history of volunteer tutoring high school and GED students, and I would love to continue to help inspire future engineers on a larger scale, so any comments about how to make this better suited for an educational experience would be appreciated. Of course my first step is just trying to get the software out there.
