    Default SDR Radio Console-AirSpy-SDRPlay-Sangean HDT-1x performance comparisons.

    Just received AirSpy SDR RX and connector adaptor and made some crude comparisons
    while still learning the finer adjustments of the AirSpy RX.
    Attached is the SDR Radio Console-AirSpy screen shot FYI.
    Below is a rough comparison of the 3 receivers (connected to APS-13 pointed ssw)
    RDS sensitivity is about equal for the 2 SDR RXs, almost as good as on the HDT-1X.

    SDR Radio Console-AirSpy-SDRPlay-Sangean HDT-1x performance comparisons .
    Receiver - Bandwidth - Images - Selectivity - Sensitivity
    HDT-1X - N/A - None - Less - More
    SDRPlay - 8mhz - More - More - Less
    AirSpy - *9.2mhz - Less - More - Less
    * rolls off on high side.
    SDR Radio Console SW is so much better in many ways than SDR Sharp SW .
    However I now am able to record/playback successfully using SDR Sharp with AirSpy, (but can't figure out how to stop the playback repeat loop)

    Sorry for the delay in commenting but the SDRplay RSP actually achieves close to 70dB dynamic range with an adjacent interferer on the FM band. See https://youtu.be/lOS0oU6FlGc - this is because the SDRplay RSP has programmable high dynamic range continuous time active filters which can be adjusted to sit at low as 200 KHz or as wide as 8 MHz bandwidth.
    the other good news from SDRPlay is we've removed the frequency coverage gap - here is the latest datasheet http://www.sdrplay.com/docs/SDRplay_datasheet_r1p4.pdf
