GNU Radio is afree softwaredevelopmenttoolkit thatprovides signalprocessingblocks toimplementsoftware-definedradios andsignal-processingsystems. It canbe used withexternal RFhardware tocreatesoftware-definedradios, orwithouthardware in asimulation-likeenvironment. Itis widely usedin hobbyist,academic, andcommercialenvironments tosupport bothwirelesscommunicationsresearch andreal-worldradio systems.
CubicSDR is across-platformSoftware-DefinedRadioapplicationwhich allowsyou to navigatethe radiospectrum anddemodulate anysignals youmight discover. It currentlyincludesseveral commonanalogdemodulationschemes such asAM and FM andwill supportdigital modesin the future. Many digitaldecodingapplicationsare availablenow that canuse the analogoutputs toprocess digitalsignals byβpipingβthe data fromCubicSDR toanother programusing softwarelikeSoundflower,Jack Audio

QRadioLink is aLinux softwaredefined radiotransceiverapplicationusing VOIP forinter-communication,built on top ofGNU radio,which allowsexperimentingwith softwaredefined radiohardware usingdifferentdigital andanalog radiosignals and afriendly userinterface. Itsprimary purposeis educational,but it can alsobe customizedfor low powerdatacommunicationson variousfrequencybands. It canalso be used asan amateurradio SDRtransceiver fordemonstratingradiocommunications
The UniversalRadio Hacker(URH) is acomplete suitefor wirelessprotocolinvestigationwith nativesupport formany commonSoftwareDefined Radios.URH allows easydemodulation ofsignalscombined withan automaticdetection ofmodulationparametersmaking it abreeze toidentify thebits and bytesthat fly overthe air. Asdata often getsencoded beforetransmission,URH offerscustomizabledecodings tocrack evensophisticatedencodings likeCC1101 datawhitening. Whenit comes toprotocol r
