6 gqrx - Software Defined Radio GUI application
7
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.
