Re: Authorized Distributor with 6mo Warranty?
I, also, bought the AURSINC unit and am quite happy with it. I don't regret paying a little more as at the time of purchase, they were the only ones I saw that were shielded.

Re: The Male Calibration Kit for AliExpress
Hello Kurt, Thank you for the detailed analysis. I do not want to tune the nanoVNA to a competitor of a HP VNA. I just want to make the best out of it with little effort, finding the weak spots and

Re: Measuring ferrite beads #test-jig
