Hi, I have upgraded to this latest version. Haven't had time yet to test for stray lines, but I did notice a minor issue when inputting a frequency. In any of the modes (start, stop, center and span)

Hi David, As Herb mentioned, it will be helpful if you submit an issue report at Hugen's NanoVNA-H master for NanoVNA-H or F303 branch for NanoVNA-H4. A detail description with operating procedure to

Hi Kurt, Are the small stray lines from measurement curves or from markers? Did you notice any pattern that causes these stray lines? Did you see this with edy555's firmware? All the above information

Hi Herb I did several test to 900MHz with the NanoVNA-Saver both with 500 point and 100Points with NanoVNA precalibrated and uncalibrated same good results The calibration kit was HP85033C and a sweep

Hi Keen Thank you I did update the H4 and used is for a couple of hours. It look good. Only in rare cases there is small straylines, e.g. just one yellow one, and it disappear very quickly. So to
