CubicSDR v0.2.2 has been released (updated)

This article has been updated on 2017-12-07 to reflect the current version of CubicSDR, which is version 0.2.2.  When we initiated coverage of CubicSDR we inadvertently published information on v0.2.0 (which is the version on the CubicSDR website).   However, looking at the GitHub page, we see that version 0.2.2  is available, and has been since May 12, 2017.  Sorry for any confusion this may have caused.   -MacHamRadio 

CubicSDR is a cross-platform Software-Defined Radio application which allows you to navigate the radio spectrum and demodulate any signals you might discover.  It currently includes several common analog demodulation schemes such as AM and FM and will support digital modes in the future.  Many digital decoding applications are available now that can use the analog outputs to process digital signals by “piping” the data from CubicSDR to another program using software like Soundflower, Jack Audio or VBCable.

CubicSDR supports the readily-available RTL-SDR which is an inexpensive SDR device that can be purchased online for about $10 and up.   Search for “RTL2832U” and “820T” or “820T2” on sites such as eBay or Amazon to see what’s available.   Additionally CubicSDR now includes support for SDRPlay, HackRF, BladeRF, AirSpy, NetSDR+, Red Pitaya, Audio Devices (some platform specific at the moment) or any other device with an available SoapySDR support module.
