Yo Gary,
many thanks for your feedback.

I have pointed out before that version 1.13 is way out of date. 1.51 is

Yes, I know. But my issue is, that this update seems to be possible only
with u-center which is available only for MS. My ZED-F9P is on a hat on
top of a RaspberryPi running Debian Linux. Some hints saying use "wine".
But wine is not running on ARM native. Needs an emulation. I will test
but probably u-center will not run over 2 emulation layers. I am
wondering that U-blox does not support at least an update tool running
on Linux.
You needed many lines to duplicate one line of example code! KISS.
I'm reluctant to admit it, but your example code is smarter :-)
I realised that it depends also on the fact which GNSS are enabled or
disabled.
Really? MON-SPAN is raw data. What did you change that affected
things?
Using a spectrum analyser it will send out a frequency spectrum and will
analyse the reflected power from the antenna. This is typically shown as
smith diagram where one can see how good or bad an antenna is at a given
frequency range. Unfortunately my spectrum analyser does not cover this
frequency range, otherwise I would test it already.
But in this case the GNSS receiver ( it's not a transceiver ) can only
receive and analyse signals coming from some satellites if they are there.
Below there are 2 examples from the L1 band:
rfspectrum_x002 shows the spectrum with all GNSS enabled which can
handle ZED-F9P, which is GPS, SBAS, Galileo, Beidou, QZSS and Glonass
rfspectrum_x001 has everthing disabled except GPS. Unfortunately at
least one GNSS must be enabled.
Kind regards
Hans
