IQQuadrature signals form the basis of complex RF signal modulation and demodulation, both in hardware and in software, as well as in complex signal analysis. at http://www.filedropper.com/gqrx201601080528581370665001500000fc

19june2017- Sounds like the NOAA-17 APT Satellite. Do you have a longer mp3 of this? I use "WXtoIMG" for decoding. 73, N6SPP
