Hi all!

There have been very impressive DIY VNA projects around lately, like hforsten, loxodes and xavna which motivated me a lot to do my own little project. Here is the description and first results of my portable 2-Port VNA. Let me know what you think!

For the transformer, you could look at Coilcraft who do all sorts of different designs. They can also supply samples, but you would need to read the small print to see what applies to your country.
