To check the radioberry driver you can use dmesg command.

pi@pi2:~ $ dmesg |grep radioberry
[    9.223522] radioberry: loading out-of-tree module taints kernel.
[    9.239079] Radioberry: inside radioberry_init function

If you have installed the radioberry driver directly from pa3gsb github repository be sure you switch off the firmware (that simulates the hpsdr protocol) demon. By executing the following commands:

sudo systemctl stop radioberry
sudo systemctl disable radioberry
