I will be giving an interesting, grass roots level presentation at Flea Market on April 13 @ 8:00am.
I have been working on understanding the NanoVNA for Antenna testing and have some interesting things to show and tell.   I guarantee that everyone will learn something.  
Do you know what a Calibration does and how to tell if you are in or out of calibration?  How about using software to talk to you NanoVNA? 
I will have a live demo of testing a sample antenna and show what happens when some parameters are changed.     
See you there.   Pat Spencer VE6PDS
UPDATE: I have posted the slides from this presentation to the website.  See https://caraham.org/Presentations
