N2PK VNA -- as this was a RSGB project I never got my arms around it --
there was a nice 100MHz VNA article in QEX July/Aug 04 by N5EG.

I'm curious. What is it exactly that you're trying to do?

Looking at RF transformers -- I am not happy with the performance of the
tracking generator in my HP3585A.

Hmmm. Okay. I confess that I never much used the tracking generator
since I had available an HP3577 for this kind of stuff.

That was when I was employed. In retirement I use an N2PK VNA.
