<p>Hi,<div><br></div><div>I've just got a funcube myself and just this morning support for it made it into the GNURadio trunk. That should make using them lots easier. I am looking forward to seeing the DVB-T support get done because that will make using SDR <i>much</i> cheaper (23USD delivered!).</div>
<div><br></div><div>The question you ask concerns the interface to the decoder... the _ff version has float inputs and outputs and the other takes bytes (actually two-bit symbols) inputs and float outputs. The latter needs a slicer before it but that is conceptually the right thing to do and so the _ff version is deprecated. Hope that helps.</div>

<p>Hi<br>
<br>
Whats the difference between these 2? <br>
<br>
I'm new to Gnuradio & python to be honest; I'm writing my own ap25 listener for the funcube...<br>
<br>
So far, I've got my software tuning, FM decoding, and then sending data into the FSK4 decoder; I can see it fine tuning.. but I don't get anything out of the decoder_bf function.<br>
<br>
Is there any easy way, to debug what its doing?? <br>
<br>
Digging around in code there doesn't seem to be much debugging.<br>
<br>
I did create some network sinks, and forward the output of the FM demod to a a scope inside gnuradio companion.. the signal looks like FSK4 with the funky phase changes.<br>
<br>
