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.
Not a really serious post - just picked up a TinySA after recently receiving a NanoVNA.. another amazing little device for relative peanuts that can be lost in a pocket!
Which one is measuring which? :)
I just got one as well, yet another cool device! Did a short review and
