I had one once!
So any plans for the application specific top-level blocks ( noaa,
pager, atsc )? I feel these could be moved to the CGRAN, or better yet
there could be a separate top-level folder for projects like this and
some of the GCRAN projects could be merged back into the ma

I've been using many USRP2s for my project. Today one of the USRP2s cannot be
recognized through Ethernet.
Only the green LED on the Ethernet port lights up.
I hooked up the Serial debug port and it says,
ethernet flow control: SYMMETRIC
LANSR:
LINK_GOOD
ethernet flow control: SYMMETRIC
Hi Sreenath,
In the case of BPSK the costas loop is properly locked when the quadrature
component of the signal is close to zero ( ie lpf[data * cos
(2*pi*f_c*t)*sin(2*pi*f_c*t)] = 0). I am not sure how you will implement this
in GRC as you have to call 'advance_loop' in the plls (inherited fro

This is pretty cool stuff. I bet the same modificat
Something to try: byte file source with one byte of 0xff, and the other 9
is 0x00.
grc is attatched, but Gaussian filter is very strongly filtering it and i
really dont understand it very well, which is needed for bandwidth limiting.
But if you dont want any filtering, you could feed file source d

Hi Everybody,
I am using USRP with daugherboard of range 1MHz to 250MHz. I am running
the program with gnu-radio 3.6.0 on Ubuntu 11.10. I am trying to run the
basic fm receiver program as shown in the video.

When you change samples_per_symbol, you aren't changing the sample rate,
but instead the divider of sample rate which gives clock for symbol rate.

Hi,
In fact I have underruns in the transmitter which means according to the
website you gave me, my transmitter is not producing data fast enough. I
guess I need a better computer for that.
Just one more question:
Are sampling rates of 20 and 25 MS/s too much for devices, more
especifically, fo
Hi Tom,
Thanks a lot for your response.
Do you know approximately when this new package will be available?
Cheers,

In the current state of gr-howto (which is also used in gr_modtool), the
SWIG stuff is done pretty intelligently by using the header files as
.i-files, which means there is no need to write a SWIG header for every
block.
One advantage of this was the possibility to add stuff in the .i-file
