The same is when I use rtl_test -p to make the ppm correction.
I have used the SatNOGS image for RPi https://gitlab.com/librespacefoundation/satnogs/satnogs-pi-gen/builds/artifacts/2019091100/raw/deploy/image_2019-09-11-Raspbian-SatNOGS-lite.zip?job=release
I will try write image on other SD card. Maybe there went something wrong.
