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.
How do you make the display brighter.
The display is very dark compared to mine other vna.
I try the 3,2" display its the same.
Is there a way to make it brighter.

I am sure DiSlord will do it in a near future ;)

Display on V2 module not support brightness ajust. On NanoVNA H4 Hugen add for Backlight LED regulator controlled by DAC.
