Re: [Discuss-gnuradio] Streaming Funcube Dongle Pro+ over UDP

[Iain Young, G7III]

Different parts of the flow graph can have different sample rates.

You need to use the rational resampler so it's output matches what
your soundcard expects.

You may also need a complex to real somewhere. There are plenty of
examples for a FM receiver on the web.
