Beware of cheap underperforming clones

As of 2022 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.

See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

Qt installed and comes up (shotcut) with message: failed to open/home/lawrence/Downloads/NanoVNA/NanoVNA_QT_GUI-x86_64.AppImage
In "help/about' This program uses Qt version 5.14.2.
Open Qt "help/about" This program uses Qt version 5.9.5.
Is this difference the issue? I simply downloaded NanoVNA/NanoVNA_QT_GUI-x86_64.AppImage and click on it.  running from a terminal, I get: NanoVNA_QT_GUI-x86_64.AppImage: command not found
Thanks in advance for you advice

If I am understanding the issue correctly, right click the file and check permissions. I had to check a box to enable it to be executable.
