I did what you suggested , removed the portsavers re-calibrated the standalone VNA,the result was better then before 0.00 db, +0.12 and -0.25 at 50k, 750M and 1500M. Then I calibrated in Nanovna-Saver using 4 segs like you, Before was better, and After was an ideal straight line at 0 dB!

Good job Jos. I initially had problems with Rune's calibration module but after he posted that you needed to start the module from a good calibration on the NanoVNA saved to "SAVE 0" it has always worked well for me. I still use the ideal models because I hate entering numbers that I don't fully understand.
Rune's NanoVNA-saver application has been working great with the NanoVNA-H4 thus far. The screen saver doesn't work because different code is required for the 4" display, and NanoVNA-saver reports the unit as a NanoVNA-H which may mean the hugen will need to change the -H4 identifier in firmware to help developers differentiate it.
