Hi, all
I just got the USRP and TXRX board and successfully installed and run
the WBFM
program to listen to some local radio station. Now I am trying to figure out
the USRP hardware
beginning from the RF section. But I found that the link about Microtune 49xx
series

Hi, all
This may be a simple question but I can not find any definite answer
from the archive.
In the module interface, there are two RF data differential pairs from
RF board to the USRP board: VINN_A, VINP_A; VINN_B, VINP_B.
If there are two individual RF tuners on the RX board,
Hi, all
I just got my 2 new TV_RX boards from Ettus, but when I installed it
and
run the tvrx_wfm_rcv_gui.py script, the script tells me that it is an unknown
board with ID 0x000c. The release of gnuradio software version is close to 2.5
(I did CVS it from the ftp site), but still far awa
Hi, Matt
Since I intend to use the TV RX tuner both with USRP board and some
of
the in-house boards (the Altera one is a little limited to my project hence
I change that to Xilinx Virtex-2 and make a in-house board), can I have the new
TV RX 2 tuner datasheet (3x8769?) ?

If the IF frequency is 43.75Mhz instead of 5.75Mhz, it is impossible that
AD9862 can be faster enough to do Nyquist sampling (64MSPs for
AD9862). If that is so, how can AD9862 sample the intended signal ?
using bandpass sampling? Matt, can you explain it a little bit more ?

Hi, all
Is there any script which is capable to replay the captured file
generated by the usrp_rx_cfile.py? It is better if I can choose either the
basic TX board (baseband only) or the USRP TVRX board (RF
upconversion). I dare not to try to cook my own script because it seems
that interpol
Hi, all
I am trying to build wxPython (2.6.3.3) on Cygwin. I just wonder
if it is necessary to use configuration option --with-opengl for the
GNURadio. BTW, if someone successfully build wxPython on Cygwin
and could share his experience, that would be great (In the Gnuradio
