Yes, github is for programmers only ;-)
I can load and execute NanoVNA V1.0.1 on my Windows 10 x64 laptop. Tried to load a s2p-file but get "Unhandeled exception". Was a standard s2p file as used by Ansoft Designer, so I do not know why it was rejected. So ist there anything special in s2p files used by nanoVNA? Any experience?
