The other "talk" that goes with the Nano VNA Analyzer is one on

Antenna Tuners: When do you need one, and how do they work?

I'd be happy to do that at some future date.

> Barry - thank you very, very much for your presentation to our club meeting, and the slide package you forwarded. It was such a delight to have you at our club meeting; there was a natural kinship we felt with you.  Your enthusiasm and thorough knowledge of the NANO VNA, and your professionalism as a teacher developed over many years were a big hit with us.  I have seen nothing but the highest praise for your presentation.  As a custom, we owe you our official club coffee mug as a small token of our appreciation so please send me a note with your mailing address; and we will get it out to you.   Happy Holidays and please stay safe.

> Licensed in 1958 (KN3EUI) as a teenager, my knowledge of electronics was nil back then, but I could memorize hundreds of questions and answers to pass FCC tests. It took me decades to really understand radio concepts, which I would now like to share with others. I am a retired physics teacher/professor with a background in astrophysics. I now love to tinker with sound card digital modes and build and test antennas. I am the net manager of the Pennsylvania NBEMS (EMCOMM) net and active in ARES/RACES in Chester County PA.
