samples to the host.  @code{rtl-sdr} provides drivers for this purpose.

The default Linux driver managing DVB-T dongles as TV devices doesn't work for
SDR purposes and clashes with this package.  Therefore you must prevent the
kernel from loading it automatically by adding the following line to your
system configuration:

@lisp
(kernel-arguments '(\"modprobe.blacklist=dvb_usb_rtl28xxu\"))
@end lisp

To install the rtl-sdr udev rules, you must extend 'udev-service-type' with
this package.  E.g.: @code{(udev-rules-service 'rtl-sdr rtl-sdr)}")
