Open Source HDSDR Alternatives

    HDSDR is described as 'freeware Software Defined Radio (SDR) program for Microsoft Windows 2000/XP/Vista/7/8/8.1/10'. There are more than 10 alternatives to HDSDR for various platforms. The best alternative is Gqrx, which is both free and Open Source. Other great apps like HDSDR are CubicSDR (Free, Open Source), GNU Radio (Free, Open Source), SDRangel (Free, Open Source) and inspectrum (Free, Open Source).
