I just found this very nice Java application written by Ward, AE6TY. He calls it SimSmith. You'll need Java loaded on your computer to run it.
http://www.ae6ty.com/Smith_Charts.html I've had some email conversations with the author, and he's been quite responsive to questions. There are two pieces of documentation on this page. I strongly suggest printing and studying them to understand the user interface. SimSmith models loss in lines. Ward says that he is continuing to work on SimSmith, and that an updated version with a new user interface is close to release. I was able to import an antenna measurement I'd made at the shack end of a known length of feedline using my Ten Tec VNA as an S2P file, and transpose it with SimSmith to obtain the impedance at the antenna. I can now use that transposed data to design a matching network. I was also able to import SWR data from EZNEC (lastz.txt) and design a matching network for it. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
