       NOTE: use rtl_eeprom -s to program your own serial number to the device

       NOTE:  if  you don't specify rtl_xtal/tuner_xtal, the underlying driver
       will use 28.0MHz

       device identifiers in the Ettus documentation.

       hackrf Use this argument without a value

       buffers=<number-of-buffers>
              Default is 32

       Only the first device found may  be  used  at  the  moment  because  of
       libhackrf limitation.

       Transmit  support  has  been verified by using the crc-mmbTools DAB sdr
       transmitter.
