Hi all,
I have several antennas. I cannot distinguish between VERT900 and VERT2450.
There is no figure on the http://www.ettus.com/orderpage.html. Does anyone know
how I can know which antenna is VERT900 which I want to connect to RFX1800?
Thank you,
Jane
hi,
I want to use Rfx 400 and Rfx 2400 daughterboards on a usrp simultaneously
to receive data from another usrp which has the same daughterboards. The
transmit way use 2 daughterboard simultaneously is ok.
but in receiving path i got nothing but gr.fr_fir_ff:using sse. it does not
call the
Dear all,
Please help me understand this output from usrp_rx_cfile.py. I have
attached the plot as the jpeg at the end:
1. I send a file with 1500 bytes of spaces (Space = 0x20 = 0010 in
binary)
2. I use usrp_rx_cfile.py to capture the samples, and focus in on roughly
24600 samples

Hi list,
I would like to install (compile) gnuradio in centos, but i have a lite
problem, always i have the same error.
./configure --enable-all-components --disable-gr-audio-osx
--disable-gr-audio-windows --disable-gr-audio-oss --disable-gcell
I am not sure about this but a similar problem is posted in this link.

I hope this works for you.

there seems to be a bug in the costas loop. As far as I understand, in case of
nonzero carrier offset, each incoming sample should be rotated with a linear
increasing phasor (assuming a constant offset). This is done with the
following code:

Hi all,
Now I'm building some signaling blocks having dual output streams.
But if I try to make dual output streams which have different data type from
input stream, 'Segmentation fault' error is occurred. How can I make dual
outputs which have different data type from input stream?
Thanks in

Thanks for the tip regarding fork(). I'll use popen() instead. :)
Still need to deal with the file_sink issue, though... fork() was only an
idea for later. Will investigate this further.

Thank you Eric,
But I still have a problem. I simply made two blocks.
1) First One

gr_make_io_signature (1, 1, sizeof (gr_complex)),
