  • Opensky - RadioReference. com Forums
    Here's a screenshot of a live OpenSky signal in Austin Texas on 935 7 Mhz as viewed through UniScope There's a remarkably clear eye pattern Apparently OpenSky is C4FM at 4800 baud (much like non-simulcast P25) That's 9600 bits per second [ insert evil mad scientist laughter here ]

  • OpenSky decoding??? Anyway to accomplish it yet?
    I have been searching for a way to decode OpenSky but haven't seen anything for this yet? Is anyone working on it? Can it be done with a SDR? Or should I give up and hope Uniden or someone else builds a Scanner that decodes OpenSky, Uniden managed NXDN and nobody thought it would happen
