Hi Rune;
I've been following your NanoVNA Saver development with much interest, and I support your wise decision to throttle back on adding features so you can focus on making sure you don't have any bugs lurking in what already exists. I've spent most of my time sorting through the firmware posts in search of which is the most bug free, which is getting supported, and is attempting to enhance performance and/or add meaningful features. I'm still not certain I'm on the right path, but I am now concentrating my focus on edy555 as the baseline reference. His 0.1.1 release seems to behave well, but things became unstable when I installed his 0.2.2 release after having tried a 2.1 GHz version (by Cho I think?).
