Click the "Power on" button in the top left corner, just under the "File" menu, to start reception. Choose the wideband FM mode "WFM (mono)" and change the frequency to a value in the FM broadcast band such as 100MHz.
The properties window appears, select the RTL-SDR dongle: It may be that the wrong kernel module has been loaded. If the GUI fails to appear, look carefully at the error messages. Once the packages are installed, connect the RTL-SDR dongle to the computer and then start the gqrx GUI from a terminal:
#Sdr dongle install#
$ sudo apt-get install -t jessie-backports gqrx-sdr rtl-sdr Make sure your local index is updated and then install the necessary packages: $ sudo echo "deb jessie-backports main" > /etc/apt/sources.list If you haven't already enabled backports, you can do so with a command like this: If you are using a Debian jessie system, you can get all the necessary packages from jessie-backports. If you did already connect it, you may need to reboot or rmmod dvb_usb_rtl28xxu. Note: to avoid the wrong kernel module being loaded automatically, it is recoemmended that you don't connect the RTL-SDR dongle before you install the packages. Without this, it is only possible to receive wideband broadcash FM radio and TV channels.įor those who want to try it out with us at MiniDebConf Cambridge, Technofix has UK stock ( online ordering), they are about £26. These typically have a temperature compensated crystal oscillator (TCXO) which is absolutely essential for the reception of narrowband voice and digital signals. It is absolutely essential to buy one of the units that has been explicitly promoted for SDR. Important: Don't buy the cheapest generic RTL TV/radio receivers. The RTL-SDR dongle also benefits from being a small self-contained solution that you can carry around and experiment with or demo just about anywhere. My recommendation is to start with an RTL-SDR dongle due to extremely low cost, this will give you an opportunity to reflect on the opportunities of this technology before putting money into one of the transceivers and their accessories.
#Sdr dongle full#
There are many different types of hardware, ranging from the low-cost RTL-SDR USB dongles to full duplex multi-transceiver systems. We provided a full demo of the Debian Hams gqrx solution at Mini DebConf Vienna ( video) and hope to provide a similar demo at MiniDebConf Cambridge on the coming weekend of 12-13 November. Thanks to the availability of a completely packaged gqrx and GNU Radio solution, you can now get up and running in less than half an hour and spending less than fifty dollars/pounds/euros. It is not exactly a new technology but it has become significantly more accessible due to the increases in desktop computing power (for performing the DSP functions) and simultaneous reduction in the cost of SDR hardware.

Software Defined Radio (SDR) provides many opportunities for both experimentation and solving real-world problems. Quickstart SDR with gqrx, GNU Radio and the RTL-SDR dongle
