We define general purpose SDR software as programs that allow the RTL-SDR to work like a normal wideband radio receiver.SDR# (Windows) (Free)
SDR#(pronounced “SDR Sharp”) is the most popular free RTL-SDR compatiblesoftware in use at the moment. It is relatively simple to use comparedto other SDR software and has a simple set up procedure. We have a fulloverview of the installation procedure on our Quick Start Page
SDR# is a simple to use program that also has some advanced features. It has a useful modular plugin type architecture, and many plugins have already been developed
by third party developers. The basic SDR# download without any thirdparty plugins includes a standard FFT display and waterfall, a frequencymanager, recording plugin and a digital noise reduction plugin. SDR#also decodes RDS signals from broadcast FM.HDSDR (Windows) (Free)
HDSDRis based on the old WinRAD SDR program. HDSDR supports the RTL-SDRthrough use of an ExtIO.dll module. To install HDSDR, download theprogram from the link on the main HDSDR page, then to use the RTL-SDRyou will need to download the ExtIO_RTL2832.dll file an place it intothe HDSDR folder. When opening HDSDR, select the newly copiedExtIO_RTL2832.dll. The other dlls that come with HDSDR will not workwith the RTL-SDR, even though they have RTL-SDR in their filename. Theofficial installation instructions can be found here
Alongwith a FFT display and waterfall, HDSDR has some extra advancedfeatures. Users will also find an Audio FFT and waterfall display on thebottom of the screen. The output audio can also be bandpass filtered bydragging the filter borders on the display. Bandpass filtering theaudio can really help clean up a noisy signal. The audio processing alsosupports placing of notch filters either manually or automatically.There are also noise reduction and noise blanker features and anautomatic frequency centering algorithm which will automatically centerthe signal, so you don’t need to click exactly in the center of asignal. Traditional ham radio users will also enjoy the S-units signalstrength meter and the built in frequency manager.SDR-RADIO.COM V2 (Windows) (Free)
SDR-RADIO.COMV2 is a popular SDR program with many advanced features. As such is it afair amount more difficult to learn and use compared to SDR# and HDSDR.Be sure you install version 2 and not V1.5 as only V2 has RTL-SDRsupport.
Once sdr-radio is installed, to get it working with theRTL-SDR you will need to compile or download three .dll files(SDRSourceRTL2832U.dll, rtlsdr.dll and libusb-1.0.dll) and place theminto the sdr-radio folder. To compile your own dlls see the instructions here
, otherwise download the dlls directly from the bottom of this link
.If the dlls were placed in the correct folder you will be able to addyour RTL-SDR as a receiver by clicking on the +Definitions button, andthen finding and adding the RTL SDR (USB) option under the search dropdown menu.
Like HDSDR, not only does sdr-radio have a RF FFTsignal and waterfall display, but also an optional audio spectrum FFTand waterfall display. Built in are also several DSP features like anoise blanker, noise reduction filter, notch filter and squelch options.The EMNS noise reduction filter is particularly good at automaticallycleaning up and clarifying voice signals.
To add to the featurelist, sdr-radio also has built in PSK, RTTY and RDS decoders, and alsocomes with a satellite tracker. Furthermore, sdr-radio has an excellentremote server which will allow you to easily set up and connect to aremote RTL-SDR server over a network or the internet. Finally, sdr-radiois capable of listening to up to 6 signals in the same chunk of visiblespectrum at a time.Linrad (Windows/Linux/Mac) (Free) (Related Post)
Linradis a free advanced SDR program with a steeper learning curve comparedto most other SDR programs. Many users prefer to use Linrad as it can beset up to have a very high amount of information density on the screenand it also has an advantage with receiving signals with the E4000 tuneras it can be made it run in a special linearity mode whichsignificantly improves the dynamic range.
Linradalso has some very advanced features not found in most other SDRreceivers. It has multi-frequency interval I/Q correction, a verypowerful “smart” noise blanker, multicast output, weak signal optimizedwaterfall, settings to aid in taking performance measurements, two RFchannel input, superior AGC and an adaptable automatic frequencycontroller (AFC). Linrad is probably the software most superior in termsof actual signal processing performance.
To install Linrad onWindows first download and run the setup-dll installer, and thendownload and extract the actual Linrad program. You will need to gothrough a text based set up
at the very beginning.GQRX (Mac/Linux) (Free)
GQRXis a free simple to use SDR receiver which runs on Linux and Macsystems. It is similar to SDR# in terms of features and simplicity ofuse. GQRX comes with a standard FFT spectrum and waterfall display and anumber of common filter settings.CubicSDR (Linux/Windows/Mac) (Free)
A new cross platform SDR receiver which is based on the liquid-dsp libraries.Studio1 (Windows) (Paid)
Studio1is a non-free commercial SDR receiver with advanced DSP capabilities,and is claimed to have the lowest CPU usage of any general purpose SDRsoftware. Studio1 supports the RTL-SDR through use of an ExtIO.dllmodule.
Studio1’s main selling point is that it claims that itsspur/alias free dynamic range is greater than 130 dB compared to the 70dB that most free SDR software programs have (spurious free dynamicrange influences the capability of the receiver to resolve small signalsin presence of in-band strong signals). It also claims that it has avery efficient DSP engine that can run well on older Pentium 4 machines.ShinySDR (GNU Radio) (Free) (Related Post)
ShinySDRis an SDR application built in GNU Radio with a web based interface. Itis currently in a usable state, but is still undergoing majordevelopment. Since ShinySDR is controlled via a web interface it caneasily be controlled over a network or the internet. It also has aplugin type development feature which allows demodulators to be easilywritten and integrated.
The current main technical advantage toShinySDR is that it has a persistent waterfall, meaning that thewaterfall can be moved, zoomed and re-tuned without loss of any historylike in other SDR software.WebRadio (Linux) (Free) (Related Post)
WebRadiois a Linux based application that is attempting to build an open sourcesystem for the RTL-SDR and other software defined radios similar to theclosed source WebSDR . The WebSDR system allows for multiple publicusers to connect to a radio over the internet and tune to variousfrequencies.

Sodirais a Windows application that is capable of decoding AM and FM+RDSradio as well as DRM/DRM+ and time signals DCF77/HBG. It supports theuse of the RTL-SDR through use of the ExtIO_RTL2832.dll module. The sameExtIO_RTL2832.dll module that is used with HDSDR and whose download islinked to in this HDSDR tutorial
can be used with Sodira. Just place the dll in the same folder asSodira, and then under Configuration->Receiver select the dll fileand then click on HW Init + Start to activate the RTL-SDR.SDR Touch (Android) (Trial/Paid) (Related Post)
