Terrific overview, Les. Some other things I’ve found in a similar assembly of test equipment: 1) The tinySA Ultra is a great device but its minimum resolution bandwidth is 200 Hz. This is just about enough to see AM modulation side bands on a carrier - so a real spectrum analyzer ($$) would have down to 10 Hz RBW and would allow a fine grain view. But consider the price differential. For anything a ham needs to do, it’s great. 2) The nanoVNA does need some understanding of its limitations - it is going to struggle with impedances >= 500 ohms or

I hadn't thought of that. Thanks for the information!
This was an excellent presentation. I purchased a TinySA Ultra because of it. -KC1RVK
Thanks. I also purchased a NanoVNA H4 after the presentation
