Here then, is a brief introduction to the Smith chart. But although questions regarding the chart appear in the Amateur Extra License exam, the current Question Pool has a mere 11 questions on the topic, leaving a full appreciation of the tool to the more inquisitive student. Here are some Installation Videos that show the process.The advent of low-cost antenna analyzers and vector network analyzers (VNAs) has resulted in a renewed interest in an 80-year old tool called the Smith chart, a graphical device used to view the characteristics of RF transmission lines, antennas, and matching circuits, and to aid in the design of those systems. The software is not 'signed' which means OSX and Windows are reluctant to allow you to do the install. In order, most recent to oldest available:ġ8.5 (Experimental) Adds a few programming conveniences like 'toLeft' and a 'switch/case' statementġ8.4 Contains custom element library support, RUSE block switches.ġ6.9 Useful when following along older videos.ġ5.1 Useful when following along older videos. SimSmith is updated with little to no fanfair. If you run into something you consider to be a bug, please update SimSmith chances are it has already been reported and fixed. If you are following a video and want to use the SimSmith release closest to that used in the video, look at the top of the screen to see the version of SimSmith being used and then choose between older versions. Under most circumstances, though, you should use the most recent realease available below. Additionaly, each dropbox folder contains a 'pdfs' subdirectory which also contains the up to date manuals as well as legacy manuals for earlier versions.Īt present, several versions of SimSmith are available. After installation, all manuals and release notes are available from within SimSmith starting at 'help' pulldown menu item. Each distribution contains installation packages for Windows, MAC, or Linux as well as the basic '.jar' file executable. SimSmith distributions are available from folders in my dropbox. I try to at least say that something has changed and occasionally say why. Please access the help menu, refering to the 'SimSmith' manual, the 'recent changes', or the 'release notes'.
If you run into this problem I appologize.
These changes can cause considerable angst, particularly when attempting to follow along while watching a video. Changes are made for a variety of reasons: adding functionality, fixing bugs, making things 'consistent' across subsystems, making things 'intuitive' for the user, meeting industry standards and/or expectations, etc. This means that over time, basic operation can change.
