Readings were all over the screen but then I noticed that Ecal was off. After changing Ecal to on, and firmware check, the unit works well. This could be one thing to check if there are problems with calibration
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.

Is it possible that "no Ecal" causes problems at calibration?
