Black Box Radios

This category includes two types of radios:
  • Conventional superheterodyne radios controlled by software, with no front panel human interface.  Signal detection/demodulation is done in hardware/firmware, with "software defined" techniques generally applied only on the last IF.   Examples:
  • Software Defined Radios (SDR).  All signal detection/demodulation is done in software.  Examples I have used include:
    • AFEDRI SDR-Net  (Ethernet capable, network SDR clients support Windows, Linux, MacOS)
    • Flex Radio FLEX-1500, 3000, 5000, and the current 6000 series
    • RFSpace Cloud-IQNetSDR, SDR-IQ, SDR-IP, SDR-14 (network SDR clients support Windows, Linux, MacOS)
    • SDRPlay, 12-bitSDR, 100 kHz - 380 MHz, 430 MHz - 2 GHz,  with support for Windows, Linux, MacOS, Rasberry Pi, and Android
    • Software Radio Laboratory LLC QS1R  (My favorite, receives 7 bands at once, and supports Windows, Linux, and Mac)
My favorite radios support open application programming interfaces and/or front ends that support multiple operating systems.  With the Qt framework, there's really no excuse for single-operating system SDR front ends.
