Hi All

So I am planning to make an open source, low cost scalar network analyser called the SNA Jr II. It was designed primarily for RF device analysis, you can find some of the details and possible usages here:

and the long story can be found by tracing the designer's blog:

I am making this for use on a variety of projects, its a very useful and cost effective tool considering all that you can do with it. As I mentioned, it was designed with RF in mind, but I though perhaps some of you who are working on cross overs and designing filters for amps and so on may be interested. Even just for general playing around, it's a nice piece of kit.

Most of the parts are commonly available, but I will probably have some PC boards made. If anyone is interested in building one of these, let me know, then I can order a few PC boards at once.
