I got a new B200, and tried to get an FM receiver working, following the
example from http://www.youtube.com/watch?v=KWeY2yqwVA0. I was able to
get sound out of my speakers, but it came out distorted. An obvious
problem is that the FM stations are spaced incorrectly on the FFT (looks
like 750kHz spacing but should be 800kHz). I randomly choose 100.3 as
the center frequency.
Attached is my flow graph, along with the FFTs. BTW, Also on the FFT of
the demodulated spectrum, I get my 19kHz steerio pilot tone at 45kHz.
Whats going on? Thanks
