Hi Matt,
Can you give me some pointers on what I would have to tweak in the
GMSK code? I read up on MSK but most demodulators I found use
integration of the I and Q phases and then proper slicing. I can see
how that works if I have synchronization, but I don't know how to
achieve that.
Here some

I, too, am about to work with the USRP and Labview. It's for our
Magnetic Resonance Force Microscope (MRFM) project:
http://lists.gnu.org/archive/html/discuss-gnuradio/2005-01/msg00232.html
This device is now run by over 100 Labview VIs that my colleagues have
built over the past 12 years.
Hi all.
I am looking at the possibility of integrating Labview into GNURadio to
demodulate FM. Has anyone out there looked into this?? What I am hoping is
that labview will be able to read the complex stream from the USRP via the
USB port.
What I need to know is
1) Once the IF frequency etc is

appearently not. I just make a simple change
d_next_input += ii; // update for forecast
return ii/DEC; // no work completed so far
Will a 2.x block consume an input stream if it returns 0 output items?
All the other atsc blocks are at least passing data and reporting
various states, but fsd = atsc.field_sync_demux() seems to be hung up.
An upstream block connected to fsd, when also connected to a file sink
only produces 28672
Hi,
Does anyone know why I get this error out of the blue when using the USRP ??
write_internal_ram failed: error sending control message: Protocol error
usrp: failed to load firmware /usr0/local/gr/share/usrp/rev2/usrp_firmware.ihx.
I was working with the USRP just fine. Then suddenly I run it
At BBN we are working on a project involving teams of
cognitively-controlled software radios, funded by the US government.
As part of this, we will be using GNU Radio on NetBSD. Due to the
current implementation of ugen(4) (generic USB devices), reads from
the USRP are not pipelined and transfer r

Can anyone tell me if there is something I can do in the
existing GNU software which will limit the output of a TX daughter board to a
preset maximum? We are using the LFTX daughter boards.
We are running the TX output to an amp that will boost the
signal up to ~8 watts, and are alread

then using the io_signature is pretty straight forward.
You might also need to change the "forecast()" method depending on how
