Hearing data bursts on 173.075 (lojack telemetry).
I have got a recording here: https://docs.google.com/open?id=0B4TfkZEkxmOYUjFrZDNrX0pSTE9BRGIzU09JdDd1UQ
The modulation format is CPFSK / FSK?
1200bd, Binary 0 = 1.5 cycles @ 1800Hz, Binary 1 = 1 cycle @ 1200Hz
Zooming into the audio sample in audacity
Is there any free program / way to decode this or maybe some sort of universal fsk decoder?
