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 V2 Plus

Hello Everyone,

I just recieved my NanoVNA V2 Plus5 (info under version menu).
The Invoice says Version: V2 Plus4 Pro (Full Set), was ordered from Tindie

Has anyone gotten this to work with vna_qt.exe, I get an Exception no Error popup.
-Tried running in Admin mode
-Noticed Plus5 it's not listed in supported devices but I think Plus4 is.

Running Windows 10 Enterprise
64-bit version

Any recomendation are welcome.

I use vna_qt and it works fine for me on Windows 10 Home Edition, 64 bit.

My NanoVNA V2 Plus4, which I ordered from Tindie around Sep 2022, says  "NanoVNA V2 Plus4" on the VERSION screen (on the device).

Does vna_qt crash immediately, or after you connect to the NanoVNA?

The vna_qt program I use is said to be v1.1. It is a single file. As a simple check, the length of the vna_qt.exe file I am running is 20479488.
