Hi abcd567,

I finally solved the problem by editing:-
sudo nano /etc/modprobe.d/rtl-sdr-blacklist.conf
and add:
blacklist dvb_usb_rtl2832u
save.
Then reboot.
After I check:-
root@orangepizero:~# sudo service dump1090-fa status

It now works. I guess something happen that “/etc/modprobe.d/rtl-sdr-blacklist.conf” has not blacklists the “dvb_usb_rtl2832u”, and causing dump1090-fa not working as normal SDR.
Thank you once again for the previous info you shared to me.
I have had installed so many times of Armbian image as well as Dietpi image for my OrangePi Zero H2+ since yesterday. I guess there are some bugs for the dump1090-fa or piaware during the setup. I have no such problem previously (few months ago).
Regards.
