Gqrx is a software defined radio receiver powered by the
|
||
|
|
GNU Radio SDR framework and the Qt graphical toolkit.
|
||
|
|
Gqrx supports many of the SDR hardware available,
|
||
|
|
including Funcube Dongles, rtl-sdr, HackRF and USRP devices.
|
||
|
|
|
||
|
|
Gqrx has the following features:
|
||
|
|
|
||
|
|
Discover devices attached to the computer.
|
||
|
|
Process I/Q data from the supported devices.
|
||
|
|
Change frequency, gain and apply various corrections (frequency, I/Q balance).
|
||
|
|
AM, SSB, FM-N and FM-W (mono and stereo) demodulators.
|
||
|
|
Special FM mode for NOAA APT.
|
||
|
|
Variable band pass filter.
|
||
|
|
AGC, squelch and noise blankers.
|
||
|
|
FFT plot and waterfall.
|
||
|
|
Record and playback audio to / from WAV file.
|
||
|
|
Spectrum analyzer mode where all signal processing is disabled.
|
||
|
|
|
||
|
|
NOTE:
|
||
|
|
To successfully run gqrx you must build gr-osmosdr with
|
||
|
|
support to your hardware (eg rtl-sdr,uhd) and have installed
|
||
|
|
on your system the latest version of libusb (1.0.19)
|
||
|
|
(you can grab it from slackware current)
|
||
|
|
|
||
|
|
NOTE:
|
||
|
|
If you use a DVB-T dongle keep in mind newer kernels already
|
||
|
|
contains a DVB driver, however, we do not want to use this.
|
||
|
|
The above "modprobe -r dvb_usb_rtl28xxu" command unloads this
|
||
|
|
from the kernel, however for a permanent solution you will
|
||
|
|
need to create the following file in /etc/modprobe.d/:
|
||
|
|
rtl.conf and add this line: blacklist dvb_usb_rtl28xxu
