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.

NanoVNA V2Plus4 version : git-20210530-412578c

Hi Walt,
Yes, after uploading 2021076 the VERSION screen will report 20210530
but with a Build Time of "Jul 26 2021" which is 20210726. So, all OK.

Cheers
Gary
