I have been working on Crystal filters using old Ex Mod xtals HC6/U from 1960's.
Matching sets using NanoVna and software from the Web, I have taken a few
screen shots, from my Win10 system running NanoVna_saver V0.3.7 & NanoVna V2_2.
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.
