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.

NanoVNA program that works with Windows XP

Hello everybody,
is there a possibility of a version of vna QT that works for Windows XP (SP3)?

Thanks for the attention.

I switch to a PC with Win7, but I have installed vna QT and it works, but I am struggling with the "nanovna saver" program that after launching a window with a black background comes out and after a while it displays script errors for a moment, then closes the window and the program does not start!

I have installed Win7 sp 1 with all visual C ++ files and the USB port of the nanoVNA is seen in the control panel (system).

I don't know what to do anymore, I ask you for help.

Hello everybody, fixed on Win7 SP1 by installing Python 3.7 and pip with numpy, pyserial, pyqt5 and spicy.
Then I installed nanovna-saver version 0.39 and launched
