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.

problem with firmware update for nanovna v2

Scott KF7GGN 2021/09/10 16:38

Hello, I am new to the forum. I have a NanoVNA V2 that was bought from Amazon, so probably one of the cheap clones that are discussed on the website. I experienced a problem when attempting to flash a firmware upgrade. Upon switching on the unit while holding down the left JOG button and releasing, the white screen remains frozen. Is there a way to fix this issue?

Thank you in  advance for any help.

Hi Scott,

I made the update with the NanoVNA-QT software without problems. No buttons have to be pressed with this method.
