I have to say, I have had more "fun" and probably spent more time using my NanoVNA 2.2 than any of my other electronic instruments except my main DMM (UT-61e) and perhaps scope. (old Tek 2211) Because the scope is so bulky, probably more than that too.
I still dont have it working 100% properly when connecting up to my computer on Linux, it appears to be a permissions problem, as I can only run it as root, which is a PITA. I'm on Debian 10. I should see if I can run it on my RaspberryPi. Is anybody else having this problem? I shouldnt have to write a udev rule, should I? I have tried a lot of different udev incantations but have not gotten it right.
When not running under sudo the software starts but doesn't see the device, even though its connected, when lauched via sudo it works fine.
