rx tools (an update of some of the rtl stuff using soapysdr\u00a0\u00a0https:\/\/github.com\/rxseger\/rx_tools<\/a><\/p>\n

rx_tools, in theory, is a good prospect, but the code is several years out of date, gives errors on devices, is unsupported – just doesn’t work yet.<\/p>\n

There are many good examples of IQ streaming with rtl_fm and rtl_tcp, but of course they only suppport rtlsdr.<\/p>\n

Prospects<\/h4>\n

pothos sdr : flowgraph\u00a0https:\/\/github.com\/pothosware\/PothosCore\/wiki<\/a><\/p>\n

**luaradio – similar to gnu-radio and looks like will run with macports:\u00a0 https:\/\/github.com\/vsergeev\/luaradio<\/a> This is a flowgraph language like Gnu-radio. But its lightweight. If the device support is ok, then it looks like there are flowgraph modules that would allow tcp data in\/out as well as audio. This is primarily a linux app – but if you ran it on r-pi it could make a good front end for a lot of devices. Also it may run in Mac OS with some audio tweaks. ie., portaudio and pulseaudio.<\/p>\n

**sdrGlut this app runs on mac os and streams iq https:\/\/github.com\/righthalfplane\/SdrGlut<\/a> – I was not able to find a method of external frequency control. It may be added in future releases as this app is in active current development.\u00a0 Also it runs sdrplay rspdx.<\/p>\n

**gnu-radio: Well supported and active development. Not sure about device support for common hobbyist radios like sdrplay, airspyhf, etc.,\u00a0 gnu-radio: http:\/\/play.fallows.ca\/wp\/radio\/software-defined-radio\/gnuradio-ssb-receiver\/<\/a><\/p>\n

**worst-case scenario. Actually build something with soapy-sdr, hamlib, and csdr.<\/p>\n
