I was an early participant in the SAL yahoo group and introduced Dan, AC6LA, to
the group. He has provided a lot of modeling tools.
That said, I lost interest after feeling that the design was too complicated,
not well understood and suffered from a dizzying number of changes. I could be
totally wrong about this, but that was my assessment some time ago and frankly I
haven't kept up.
