NAME

6       gqrx - Software Defined Radio GUI application
7

DESCRIPTION

9       Gqrx  is  a software defined radio (SDR) receiver implemented using GNU
10       Radio and the Qt GUI toolkit. It works with hardware supported  by  gr-
11       osmosdr,  including  Funcube  Dongle, RTL-SDR, Airspy, HackRF, BladeRF,
12       RFSpace, USRP and SoapySDR.
13
14       Gqrx can operate as an AM/FM/SSB receiver with audio output  or  as  an
15       FFT-only  instrument. There are also various hooks for interacting with
16       external applications using network sockets.
17
18       It is strongly recommended to run the volk_profile utility before  run‐
19       ning gqrx. This will detect and enable processor-specific optimisations
20       and will in many cases give a significant performance boost.
21
22       The first time you start gqrx it will open a device configuration  dia‐
23       log.   Supported devices that are connected to the computer are discov‐
24       ered automatically and you can select any  of  them  in  the  drop-down
25       list.
26
27       If  you  don't see your device listed in the drop-down list it could be
28       because:
29
30       •      The driver has not been included in a binary distribution
31
32       •      The udev rule has not been properly configured
33
34       •      Linux kernel driver is blocking access to the device
35
36       You can test your device using device specific tools, such as rtl_test,
37       airspy_rx, hackrf_transfer, qthid, etc.
38
39       Gqrx  supports multiple configurations and sessions if you have several
40       devices or if you want to use the same device under different  configu‐
41       rations. You can load a configuration from the GUI or using the -c com‐
42       mand line argument.
