These are some of my recordings. Its on GQRX Format. for those who want to parse outside GQRX: It's a raw Float Complex IQ file ( I Q I Q ) and the file name gives the parameters: For example: gqrx_20161202_145551_1691000000_1250000_fc.raw 20161202 is the date of the recording 145551 is the time of recording (UTC) 1691000000 is the center frequency in Hertz (in this case 1691MHz) 1250000 is the sample rate (in this case 1.25Msps) It may also contain a segmentX in the end of the file name. That means that is a smaller segment of the main file (the one without the segment statement in the filename). The format is the same. The gqrx_20161215_163848_1691000000_1250000_fc.raw file has a better SNR (10dB) Have fun! Lucas Teske
