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.

I can use the TDR just fine on the nano and it works very well.  I shorted a 4' piece of coax and the
TDR graph spiked at 1.21 meter which is 4'.  I'm impressed. But for the life of me, I can't figure how
to use the TDR (Time to Fault) in the software.  ????
