RichHope that helps,Hi Hoang,Yes it's a problem with your design. You have 2 Msps feeding into an audio sink that probably goes up to 48 ksps. You need to change your sample rate from 2 Msps to a rate your sound card supports. I would target one of the default rates you can select from the audio sink. You can use polyphase arbitrary resampler block with the proper resampling ratio 2M/48k entered leaving the taps blank and the other parameters to default.On Fri, Aug 28, 2015 at 2:19 PM, Hoang Nguyen Tran <address@hidden> wrote:_______________________________________________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 2Mcut off freq 9600transition 4800
I really appriciate for any comment on my FSK receiver flowgraph, I am a newbie :)
Thank you and best regard,Hoang
