Small GUI control panel for remote control of Gqrx (https://www.gqrx.dk/) for fast sweeps through the spectrum. (That might be helpful, if you plan to abuse Gqrx for spectrum analysis instead of software radio stuff.)
Gqrx-sweep controls Gqrx's frequency by sending commands via telnet.
- Open Gqrx as you normally would.
- Enable 'Remote control via TCP' by clicking the icon with the two PCs in the main toolbar. (The main toolbar toggles with 'ctrl'+'T')
- 'Configure remote control settings' by clicking the icon with the tools in the main toolbar. Make sure Gqrx's remote control settings (port, host) match gqrx-sweep's configuration in the config.ini . By default, the port is 7356 and the host is 127.0.0.1 .
- Open gqrx_sweep.py with python. ('python gqrx_sweep.py') A small GUI should open where you can enter the frequency of your choice.
- You can set a frequency by entering the number or using the slider, and you can use the 'frequency sweep' function to automatically sweep through the spectrum.
gqrx-sweep is a Python application based on PyQt5 for the GUI.
- You need the Python package pyqt5 installed.
- The other packages should already be installed with a standard installation: os, sys, configparser, telnetlib, time
