NAME

       gqrx - Software Defined Radio GUI application

DESCRIPTION

       Gqrx is a software defined radio (SDR) receiver implemented using GNU Radio and the Qt GUI
       toolkit. It works with hardware supported by gr-osmosdr, including  Funcube  Dongle,  RTL-
       SDR, Airspy, HackRF, BladeRF, RFSpace, USRP and SoapySDR.

       Gqrx  can operate as an AM/FM/SSB receiver with audio output or as an FFT-only instrument.
       There are also various hooks for interacting  with  external  applications  using  network
       sockets.

       It  is strongly recommended to run the volk_profile utility before running gqrx. This will
       detect and  enable  processor-specific  optimisations  and  will  in  many  cases  give  a
       significant performance boost.

       The  first  time  you  start  gqrx  it will open a device configuration dialog.  Supported
       devices that are connected to the computer are discovered automatically and you can select
       any of them in the drop-down list.

       If you don't see your device listed in the drop-down list it could be because:

       •      The driver has not been included in a binary distribution

       •      The udev rule has not been properly configured

       •      Linux kernel driver is blocking access to the device

       You  can  test  your  device  using  device  specific  tools, such as rtl_test, airspy_rx,
       hackrf_transfer, qthid, etc.

       Gqrx supports multiple configurations and sessions if you have several devices or  if  you
       want  to  use the same device under different configurations. You can load a configuration
       from the GUI or using the -c command line argument.
