I am also one of the "few radio enthusiasts" who would do this, and in fact, the first thing I did when I got my first tinySA was look at close-in performance.? I was hopeful, but it won't do SSB transmitter IMD tests.? But I have another SA that will, and the tinySA will do so much amazing stuff, including LOTS of things that my bigger, much more expensive SA won't do, or won't easily do, so the tinySA is well worth the price..? I currently own 3 tinySAs, and I'm thinking about getting another one to keep in the car.? (You never know when you might need a spectrum analyzer, you know.)
I believe that the close-in performance of the tinySA can be improved somewhat, but haven't had the time to do experiment with it, and even with the improvements I have in mind, it still won't do SSB transmitter IMD tests.? Nonetheless, a fine piece of equipment.? Everybody should have one (or several).
