Beware of cheap underperforming clones

As of 2023 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.

Saving calibration to a file - NanoVNA V2 Plus 4


Michał Frątczak 2023/10/08 04:29

I have a bunch of calibrations saved to 0-5 memory slots.
These CALs are for different HF bands and for a specific piece of coax that is now installed to antenna on mast.
Is it possible to somehow save these calibrations for later use? Maybe one of PC apps like NanoVNA saver can do this ?
I would like to be able to measure my antenna from time to time, but obviously I won't be able to recalibrate for this specific COAX.

Hi, the VNA View (NanoVNA-QT) software can save calibration files:

You can find the "Save" option under the "Calibration" menu.
Thanks
