I'm way behind on the learning curve. I had read about that Vector
Network Analyzer last year. it looked too complicated for me to build.
And, in my ignorance, I thought that system was what the MFJ used.

The Smith Chart plots from his VNA data really impresses me. I could
possible get interested in building something like that for VHF, if I
understood it.

Software would do that.

No it wouldn't, unless you could figure out some way to get vector
magnitude
and phase from the two channels.

Hi All,

I have since researched the archives to find my reference:

What can be done, what has been done, and what might be inferred is
revealed at this page.
