    Hi John,
    I am still very much enjoying linsmith. I thought you might be
    interested in my latest antenna project where I used linsmith to help me
    get the matching components sorted out. I did up a quick webpage with
    the antenna build details and a plug for linsmith!

    http://ve7it.cowlug.org/6m-five-eigths.html

    The slider controls for adjusting components in the matching system is
    just magical to watch on the animated smith chart. The math doesn't lie!

    3 days of fumbling with guesses for the matching network were quickly
    solved using linsmith.

    cheers

      Hi Lawrence...

      Great to hear from you again! And of your continuing use of linSmith.

      There are are some clouds on the horizon though (like the ones that
      are really forming outside there's a large storm coming). Debian will
      discontinue its support (rightly, I think) because of the old gnome
      libraries which are still in use in the latest version. I suspect
      other distros will follow.

      So, I've basically re-written large parts of linSmith to not use those
      libraries, use a newer version of the graphics canvas, and streamlined
      some other issues. And ported to Gtk-3, which was long overdue. It's
      working, but I'm trying to debug a somewhat exotic value problem which
      appeared in the process. Strangely, I can't seem to debug near the
      point of the segfault. Either it doesn't happen anymore, or it happens
      at a different place.

      I doubt a simple merge will be possible with all the changes.

      Anyways, I just wanted to give you a heads-up that I haven't given up
      on the project.

      Cheers,

      John
