I/Q Raw Recording
Audio Sample

FSKFrequency-Shift Keying signal, seems to be 3 or 8 tones. The baudBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. rate is very slow. The frequency shift is either intentional or this is doppler shifted, like a satellite? Due to the strength of the signal, I think this would be more local.


Decoding Software[edit]

Found using SDR# and RTL-SDR dongle, 6 inch telescopic antenna by the side of the window, this signal is very strong.
