[Discuss-gnuradio] FSK receiver

Dear all,

I have just built a FSK receiver aim to receive Cubesat data with FSK modulation with 9600 baud rate, below is my flow graph.

I have just tested it with usb dongle RTL-SDR, however when I'm using audio sink, I received  OOOOO (overrun I think) continuously .
Does it have anything wrong with my set up ?

samplerate 2M

cut off freq 9600

transition 4800

I really appriciate for any comment on my FSK receiver flowgraph, I am a newbie :)

Thank you and best regard,

Hoang
