I have NanoVNA-App-1.1.206 up and running on Windows 10 20H2 with a NanoVNA-H
and DiSlord Firmware v1.0.39.
Everything seems to work and I have also uploaded firmware. However, the data
that is produced differs from what I see on the NanoVNA screen and also on
NanoVNA Saver.
As one example, the lowest VSWR on my 440 MHz ground plane antenna shows as
448 MHz on the NanoVNA-H and NanoVNA Saver. NanoVNA-App shows the lowest VSWR
around 452 MHz. Similar differences were seen with a 17 meter antenna.
NanoVNA Saver was not run until after the problem was noticed and NanoVNA-App
was shut down first.
I've tried many things without success. The frequency settings match between
the NanoVNA and NanoVNA-App. I have turned the NanoVNA on and off several
times and also let the system create a new NanoVNA-App.ini file.
Thanks for any help.

You have to make sure you have selected the right source for the calibration data.
There is a dropdown box to select None VNA or APP. Pick VNA if you want to use the calibrated NanoVNA. Use APP if you want to calibrate in the program.
