Hi guys，
Could anybody can help me for these problems？
1、I varied Tx_amplitude from 0.1 to 1 and measured the output with a
spectrum analyzer. But the changes are very little. The output is almost the
same when Tx_amplitude is 0.1 and 1. How can I reduce the transmit power to
a very little
Hi Josh,
Thanks for replying.
I tried what you told me to do. I added %includeusrp2/usrp2.h and maked
the directory. However, I receive this error;
usrp2.cc: In function ‘PyObject* _wrap_usrp2_start_rx_streaming(PyObject*,
PyObject*, PyObject*)’:
usrp2.cc:7970: error: ‘time_spec_t’ was not
Thank you for the hint. Installation was successful with gnuradio 3.3.1.

1. Change tx-gain if you are using tunnel.py. The default value is set to
the mid value. Use -h to find out more.
2. Spectrum analyzer would help you to observe. I believe you can also
calculate based on your settings. Maybe someone can point out where in the
code the bandwidth relationship is

Anyone on this list know anything about coherent de-dispersion
filtering, and how it's supposed to work?
I've had one implemented for years, and still don't really know whether
it works or not, looking for
clueage about how to test it. Maybe there's *somebody* who knows
something about 'em?
Hi,
I am trying to get USRP2 with RFX2400 daughterboard working on Ubuntu
9.10 (karmic). I have followed the instructions here
(http://gnuradio.org/redmine/wiki/1/UbuntuInstall).
I installed the firmware and FPGA code on the SD card from

Looks like it continues to consume cpu, but at a lower rate than normal.
When it wedges, you should be able to attach to it with gdb.
Run gdb on /usr/bin/python,
