Where to bye a good quality and accurate 50 Ohm SMA Load ?
Cheers, I had the same issue, placed an order through our business to get SMA calibration kit from kirkbymicrowave. Money spent, nothing arrived, my advice is against. Can anyone post here what happen

Had only issues with "INDUCTOR_MA...' file not able to fit. Thanks for the sample data of the real life scenario where VNA calibration fails. I may add some diagnostics in code to tell why. web.de@gro

Nice to see Maël, you are also working on HamVNA updates. I can relate to your findings, also did many changes for my own use, starting with version ported to Lazarus, to avoid any licensing issues wi

What is the power rating of the 50 Ohm dummy load provided with the nanoVNA?
look on eBay for cheap high power low inductance load resistors for RF.

Metal Detecting with NanoVNA
Who can forbid using NanoVNA as a metal detector? Mind low frequency limit of this device and poor resolution not so good for metal finding using S1. Looking at S2 from Rx coil perpendicular to Tx coi

The necessary dll files are together with exe in the source folder. At least in my repository. I know that I should sign/certify the file for using smooth with Win 10. Will do on the next occasion. As

I find this topic non-trivial.. I usually measure components with S11 only and for displaying impedance and creating equivalent circuit use a copy of HAMVNA originally by Alex VE3NEA, I modified and c
