[Hackrf-dev] FM receive difference between HackRF and RTL-SDR

[Simon IJskes]

The experience sounds the same as my first attempt, under linux, with 
the old osmosdr software, where the magnitude of the signal was 
incorrectly assumed to be unsigned.

After fixing this, it all sounded a whole lot better.

Maybe this is also the case in your setup?
