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.

Broken input

I can calibrate my Nano Vna V2 but results are still totally random. I think I was too lose while soldering and broke the input IC. What is the name of that IC. I think I saw a thread about changing it. Can I have link. And has anyone really done it.

If it is possible, I have to buy some overvoltage ESD diodes for the input.

Those diodes with an easy name are very small, it will be hit and miss operation to solder them.
A new Nano V2 costs 200@£$, it was an expensive mistake.

Luckily, I have a plain Nano Vna too, so there is no rush.
