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.
Hello, I cannot use VNA-QT on a Win 10 PC, the driver is involved, I reinstalled it I changed the USB socket,
but nothing wants to work! I did a test on another Wnd 10 pc and it works? help please
Thank you Roger ON4BK.
Common problem in Windows. Check the Windows Device Manager. If there is
a COM port associated with the VNA, then it should work. If - likely -
no COM port found, check for unknown devices and try to update the
driver (with Windows default settings). Did the trick for me.

Hey Roger
updated windows version 2004 ? this messes up the driver.. it finds a Serial to Uart.. but no com port.
even no Unknown Device...
did try with original Cypress Uart driver.. but no advance..
Didn't find any solution for the moment..
I reverted to version 1909
It worked again..
Strange

Hello JP.
Thanks for the information, Windows 10 (1909) version works fine for NANOVNA-QT.
