Hi,
It seems that there is a bug in gnuradio 3.1.1 (and up to today latest truck
revision) in the USRP rbf standard file. When trying to change the
interpolation rate dynamically, the output get distorted badly even if the
program restore the started interpolation value. I have an old gnuradio
I've been doing some testing with a new USRP (manufactured 12/2007). My
configuration is an Intel USB interface on a P965-S motherboard. I dual-boot XP
SP2 and Arch Linux. In XP I've used Cygwin and MinGW. I've tried removing all
but the TVRX board (which is mainly what I'm attempting to test),
Hello Everyone - I am doing my best to understand how the TVRx board
works. I have Rev. 3 of the TV board, with MicroTuner module with IF of
~44 MHz.
(Preface - Thanks for your patience, as I am relatively new to GNU radio
and the USRP!)
In my experiment, I have an 80 MHz sine wave at 2 mV pk-pk
Hello folks,
I want to try some working transmitter and receiver GSR package. It seems
most emails in the archive are talking about receiving while I'm interested
in both transmitting and receiving. I prefer to have a system with a
bandwidth of 8 MHz, but I'm willing to settle for 6 MHz if it is t
Hello all,
I want to perform some simple boolean operations on a stream of data.
For example invert the bits from the output of the demodulators or convert
from NRZ to NRZI
I was thinking something like
1) gr_xor_bb, gr_and_bb, gr_or_bb, br_not_bb ...
or
2) maybe gr_boolean("xor") , gr_boolean(
Thank you for the reply. That is the script I use for reading in the data
into MATLAB. I should have made that more clear.

The data format is alternating I and Q single-precision floating point
in whatever endianness your computer is. See the following for how to

Hello,
I'm a student trying to use the USRP with the TVRX board to do a simple FM
stereo receiver. I previously wrote a MATLAB model of a FM transmitter and
receiver, and I wanted to use real data in my model. I've been modifying the
wideband fm example to record data from the TVRX board by basica

I've read that post before. It more or less gave me reassurances on what
I had gathered that had to be done to implement a simple in-line
multiplier in the TX chain. The post tells me what registers are
readback, but not how to read them back. When I came across the post
originally, it pointed m

Hi Dan and Tom,
Thanks for your comments. I'll trying changing the parameters and look
at the log files to see what might be wrong.

As you will see in my original email, the problem is inside of the OFDM
receiver, and I pointed out what that issue is and ho
Does anyone have any UK analog UHF TV sample data? Just before they turn it
off ...
Thanks
