It is 17 sec data dump from FM radio channel. Taken using cheap, $15, Realtek RTL2832U(?) based device. I used famous SniffUSB 2.0 sniffer to capture it, as I usually do. Then I made simple Python script to extract that data to one file. There is maybe 5 sec "empty" before channel was tuned since sniffer was started before Realtek Windows FM application. This can be seen easily when examine dump using Audacity or some other tool. Could someone try to decode out voice from it? I think GNU Radio is way to go... After all I wonder if that device could be used as cheap replacement for famous USRP software radio... Even partly for some limited modulations. For my eyes it looks like DVB-T demodulator ADC is used to sample IF frequency from the tuner chip. And those raw ADC samples are passed to the computer for decoding. I have newer before seen such is possible for any other DVB-T demodulator. Antti Palosaari
