.SH NAME
|
|
gqrx \- Software Defined Radio GUI application
|
|
.SH 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.
|
|
.PP
|
|
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.
|
|
.PP
|
|
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.
|
|
.PP
|
|
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.
|
|
.PP
|
|
If you don't see your device listed in the drop-down list it could be because:
|
|
.IP \[bu]
|
|
The driver has not been included in a binary distribution
|
|
.IP \[bu]
|
|
The udev rule has not been properly configured
|
|
.IP \[bu]
|
|
Linux kernel driver is blocking access to the device
|
|
.PP
|
|
You can test your device using device specific tools, such as rtl_test,
|
|
airspy_rx, hackrf_transfer, qthid, etc.
|
|
.PP
|
|
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.
