As part of some GNU Radio infrastructure work, the Coverity static
analyses is running again. Thanks guys!

This is a great way to find places the code needs some work and a good
way to start contributing to the project. Go ahead and take a look!

Hi all,
I just found I can't use the iwconfig tap0 rate 20M to setup the bandwidth
of the tap0. The error message is :
Error for wireless request "Set Bit Rate" (8B20) :
SET failed on device tap0 ; Operation not supported.
But in their video , it can be set in this way. May I know how t
Hi Luca,
Nice to see your progress so far. Once you have the
DAB receiver audio listening in place, I would
suggest to have an audio synchronization for continuous
playback without any buffer overflow or under-runs.
DAB+ audio super frame length is 120ms according to DAB+
standard (ETSI TS 102 5
Hi ben,
I love this topic of how to match hardware clocks just as much as you
do, but I personally think that solving the two-clock problem between an
SDR receiver and an audio device might be just a tiny bit out of scope
of a GSoC project on a broadcast standard implementation. Also, it's not

I'm creating a Python block that calculates a custom FFT. I need to ensure
that I get at least 1024 data points for every input to the block.
>From my reading, it looks like I should just be able to do this with the
forecast() function in the Python block. So I've done this:

I may have just answered it. I change the sync_block to a basic_block and
it seems to be working.

I don't have a view whether an audio synchronizer (is that the right
term?) is appropriate for GSoC, but it's a problem that's biting me
right now. I'm doing a multi-channel nbfm receiver with a polyphase
channelizer that feeds a bunch of power squelch/nbfm demod blocks, with
the audio streams

Hi Benny --
As I mentioned in another message, I'm struggling with the RF-audio
interface now. Do you have any example code for your suggestion that I
might play with (in my mind, the idea would be an "audio synchronizer"

I have a rather complicated GR application. I create (Python, w/out grc)
multiple top_blocks, each containing dozens of blocks. To make things even
more complicated, the flowgraphs are created in stages - using runtime
reconfiguration to add more blocks.
Everything works fine until I reach so

I'm trying to implement a Python block that will take a signal (complex64

So something with an input array of 1,024 complex elements and an output
