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.

You have not calibrated properly.  You can tell by the left hand side of the screen it only has CD.

Carefully follow calibration instructions.

Hello,

I think I see a LOGMAG scale of 0dB per division. Maybe just a scale configuration?
