I have had my Nano VNA now for about 10 months and I think I have now exhausted everything I can do with it.
A year ago I could not tell you what the letters "VNA" even mean (I did know what nano means).
But ideas pop up and I have to pull the Nano VNA out again and try something new.

I've done so much that I now have way too many slides for a one our talk, or even a two hour talk.
But I have divided this PPT into two parts:
Part I The Basics - I try not to get too deep into the weeds
Part II Advanced - much more in depth stuff, and stuff on antenna impedance and matching

I've given "live" Zoom talks now to over a dozen clubs, throughout the USA and two in Europe.
This has been a learning experience for me in many ways.
So I want to thank those kind enough to offer suggestions (and point out errors).
You know who you are.

So perhaps this is not a complete story yet, but I hope this contains some slides for useful discussions.
If you do spot an error please let me know (off list at k3euibarry@...)

Please use this resource any way you feel appropriate.
I hope I did not violate any image copyright laws as I put these slides together.

And here is last weekend's ZOOM talk on Nano VNA Part II (Under the Hood Advanced stuff)

This is about as far as I can understand - right at my envelope of understanding.

Watch this video if you have time on Nano VNA "advanced"

This was recorded by a ham radio club in Portugal.



I've played with this Nano VNA "tool" now for about 10 months. What a journey.


Last Friday evening I gave a talk on the Part II Nano VNA to a Portugese Amateur Radio Club (in English).

This was way beyond the 6th or even 9th grade approach.

I was stretching my envelope of understanding as I prepared this talk, and then gave it in a bit over one hour.

I think this is as far as I can take this topic.

The learning for me took place over months of "playing" with this Nano VNA tool.

TU for this way-cool gift.


Enjoy if you care to watch this video, with lots of questions and discussions by the participants, some in Portugese.

Barry,
Many Thanks, I will distribute this to our Club since many have shown interest in the Nano VNA but have avoided purchasing since so many "fake" units are marketed and we are assisting in providing reliable "Real" sources.
This Fields Day antenna setup was a fantastic "proving" ground and my Nano was a busy beaver.
Best Regards.

Barry, Can't thank you enough. You did an excellent job putting this together.... finally, something I can understand.

Hi Barry,

This was really amazing, thank you so much for putting it together. I've been going through while waiting for my -F to get here from China and it's been really helpful. The "grampy pushing swing" analogy helped me probably more than anything else to understand that concept in my >20 years as a ham.

I do have one request: Could you post the "answers" to the "which of these has the lowest SWR/which is resonant/etc" for the questions on the Smith charts? I'm sure when you present this you go through it but I'm not sure if I got the correct answers.

Thanks again.
