QUOTE: 1) What is the persistence of calibration done through
nanovna-saver? I.e., does it persist if the USB cord is disconnected and
the H4 is taken for mobile measurements?
Any cal done within SAVER stays with SAVER. Any cal done on the native
NANOVNA stays with the NANOVNA. They do not cross pathes.

2) Is the calibration done by nanovna-saver dependent on the calibration
done by the H4's internal cal? For instance, say memory #0 on the H4 has a
bad calibration stored. Since this is the default used by the H4 when it
boots up, will it corrupt the calibration done in nanovna-saver. Does
nanovna-saver depend on the calibration state of the H4 to be correct?
The cals done on the native NANOVNA and within SAVER are independent of
eachother.

3) Is is possible to store the calibration done in nanovna-saver to one of
the memory states in the H4? Storing it in memory #0 would allow for a
calibration to be persistent through a power cycle.
The cals between the native NANOVNA and within SAVER are independent.

I use nanovna-saver with my H4 because it aggregates several useful
functions for operating, storing, printing, and exporting measurements. I
am confused about the calibration done from nanovna-saver. I know I can
load and save calibrations on my PC as files. This works and I use it all
the time. I wanted to take the H4 out to the yard and do measurements at
the antenna after I calibrated with nanovna-saver. It seems that it did
not retain the calibration. I don't remember if I had turned the H4 off,
then back on, but the results were different when I then brought out my
laptop and loaded my calibration file. Everything seemed to measuring
correctly, after that. So I have some questions;
1) What is the persistence of calibration done through nanovna-saver?
I.e., does it persist if the USB cord is disconnected and the H4 is taken
for mobile measurements?
