I received this email from SDRPlay Support:
> The API [http://www.sdrplay.com/docs/SDRplay_SDR_API_Specification.pdf] provides IQ data so you would need something that takes IQ into a demodulator for the standard you are interested in. If you can find that then we provide API documentation so that you can write some software to setup the RSP correctly to get the right IQ stream for your demodulator software.
So, I suppose I need to figure out what demodulator software takes IQ streams.
