    Quickest Way to get a HackRF up and running on OS X (El Capitan)

    This is the quickest way I've found to get the HackRF One up and running on OS X El Capitan. Most of this can be ran unattended, overnight. Just make sure that you turn off any power saving mode during the install process. It took me for ever to compile gcc5 because I kept on letting my computer...

    $30 sdr rx

    I'm surprised the RTL-SDR hasn't shown up here yet. It's a DVB-T USB dongle that has a nifty feature, the receiver IC can be set to send the I/Q streams raw over USB to the host computer. There's a GNURadio driver for it. It only has an 8-bit A/D but can run up to about 2.8Msamples/sec...

    GNURadio to DSD

    DSD wants to read from /dev/audio, or from a file written to with DSD. Is there a method of getting a stream [presumably demodulated audio, if DSD is used to reading from a soundcard] from GNURadio into DSD, preferably in real time?

    Gnuradio Debugging

    Hey, all. I am developing a block in Gnuradio (using GRC). My block is just eating up memory and I can not figure out why. Does anyone out there know a way I could use gdb (or any debugger) to step through the runtime process and watch the memory get allocated? Thanks in advance.
