Absolutely no need to buy a second calibration kit. The kit supplied with the nanoVNA is good

For meticulous as I am, About the 3rd time I calibrated my NanoVNA 2-3 years ago.. Calibration was funky and the supplied 50 ohm load was, I recall OPEN... Fortunately AMAZON? solved that with a pair of 50 ohm SMA loads for very little money..
I chalked it up to ADOA...Almost Dead on Arrivial.?

Thank you for bringing the Amateur Radio Community, this wonderful item. I have both the NanoVNA H4 and the TinySA Ultra plus quite a collection of adapters, attenuators and a 0-1Ghz LNA? I have used for repairs, and experimentation, and alignments of pass band cavities.
